So far there's just one Vega eGPU setup in our table: This one. I haven't seen 4K results for eGPU Vega anywhere.

Got my Vega64 Liquid today, thrown it into my eGFX 350 with a new powersupply... as soon as 3D stuff comes up it tends to have freezes for several seconds (Steam with TerraTech) apps like "Maps" tend to crash the system with no response at all. Could it be due to Power supply shortages and stuff or is the driver just very premature?

I tested a bit, as soon as I start other apps the same freeze happens and the Fan/Pump kicks in full throttle, any suggestions if those "bios power setting switch" could help?

Within Console I find at least 3 "gpuRestart2017-08-31-165..." files all with some partly readable information afterwards it looks like a memory dump which is not human readable...

I am not sure if Apple officially supports Vega10 yet.

Meantime, can you please try the following (to eliminate insufficient power for GPU):

- attach your laptop's power supply so your eGPU box does not provide the power to the laptop (and ensure that there is nothing else power consuming is attached to eGPU box)

- What is the power supply you are using? is there any possibility to try a a bigger power supply?

Sure it somehow looks like not being fully supported yet. GeekBench gives me an "AMD Radeon HD Vega10 XT prototype compute engine" my internal RX460 is called like this "AMD Radeon Pro 460 Compute Engine" through GeekBench. Interesting wise "Vorschau" I think its called preview in the English version dosen't open up an window at all. Within System Information I see the following:

AMD RX xxx:

 

  Chipsatz-Modell: AMD RX xxx

  Typ: GPU

  Bus: PCIe

  PCIe-Lane-Breite: x16

  VRAM (gesamt): 8 GB

  Hersteller: AMD (0x1002)

  Geräte-ID: 0x687f

  Versions-ID: 0x00c0

  Automatischer Wechsel der Grafikmodi: Unterstützt

  gMux-Version: 4.0.29 [3.2.8]

  Metal: Unterstützt, Funktionsset OSX_GPUFamily1 v2

 

  Displays:

DELL U2412M:

  Auflösung: 1920 x 1200

  Framepuffertiefe: 30-Bit Farbe (ARGB2101010)

  Display-Seriennummer: 19K*****ML

During the tests my MBP 2016 15Inch was powered through the LG5K Ultrafine. After having crashes there I switched over to an 87W Power Supply without any changes in behavior. As the new PowerSupply within my eGFX350 I am using an SST-SX600-G, which according to manufacturers data sheet information is capable of 50 amps on the 12V rail and have two 6+2Pin Connectors. Voltage regulation is said to be within 120mV of ripple peak to peak. Within their document they also claim it could support two GTX1080 or one TitanX.

 

Update: 

i tested a bit around, opening up my 350. the pump noise was kind of heavy so I tried to find the spot to somehow dampen it down a bit. During this I noticed. "Maps" is creating a 100% load for the Vega64 and as soon as the last red load digit lights up I can hear a sound which I remember from big inverter units when they are heavily under load. For me this was a bit of an concern due this usally is a sign of overload for those systems. Through this I now flipped the DIP-Switch which is located near the end of the card and reloaded the system. now if the system hits 100% this noise is significantly lower and at the same time the GPU doesn't spin up the pump as quickly.. maybe this is this power saver / efficiency mode which some talked about on twitter? Will keep testing lets see if I can crash it again with this setting, if not I think you might be exactly right about it being an power delivery error crashing the card an some screwing up the driver through this

As i suggested in the other vega thread in this forum section, where nobody post and read, you should have waited a bit before get vega!

Especially for an eGPU use! Well i wish you good luck!

I know that this purchase was quite early especially regarding how fresh eGPU support is and Vega too. But still I hoped that due to the oncoming iMac with Vega support had already progressed a good bit further. Previous to the Vega64 Liquid I successfully ran an RX580 8G for about two weeks now.

At the same time I'm not sure if the liquid version was a good choice due to the pump being quite loud or lets say audible in contrast to standard fan noise. Every reconnect/boot of the eGPU it goes full throttle to calm down after a few seconds. The noise it does while doing this doesn't sound that appealing.

using an oscilloscope I checked the 12V rail during a test with unigine Heaven benchmark and you really can see how the noise level on this rail increases with load from several 10-20mV noise up to about 500mV absolut maximum during full load.

 

btw. I ran an 4K Dell Monitor just a few moments ago with the RX580 sucessfully on 30Hz (DP1.1) and 60Hz (DP1.2) but with the Vega I'm not getting any signal at all no matter which DP protocol version I select within the monitor. I haven't tested HDMI due to the fact that this monitor is only capable of 30Hz @ 4k using HDMI

As i wrote and state again, Vega is a powerful compute architecture, but lack driver and feature support at the moment to be used mainly as eGPU. The die architecture is too much advanced for the drivers and developers to follow behind. AMD do not have the same driver/developer market shares than Nvidia to allow quick improvement at day lunch i.e cuda support, you need to wait a bit.

Maybe some liquid Vega suffer the same issue that the Fury had, the 1st batch had a bad and loud pump. You need to asses if the pump is loud during normal operations, at boot it is normal, could be some pump/fan speed check or lack of control at boot by the bios. Otherwise the watercooling system itself is really well done, featuring even a liquid tank for long lasting AIO cooler capability. You can change the fan by buying a mini 4pin to normal 4pin PWM adapter and then use another branded fan. 

Your SFX 600Watt is maybe not enough, not because of the current rating of 50A, but because of the small factor psu, since in my opinion the psu will be fully loaded even if the current capabilities should be fine. You need to assay again with normal branded psu with at least 400Watt of power delivery, 500Watt would be the nice spot. Removing the peak consumption from the equation, Vega draw on average 400Watt from the psu. That's why you notice so much ripple on the 12v rail, the switching rates or the capacitance of the SFX psu are not strong enough to provide a stable voltage/current delivery.

My R9 [email protected]@1.3v that draw as much as Vega and it bow my 1000Watt psu during summer, the psu heat up quickly. I have noticed that if i do not clean my psu an let it overheat, i got strong degradation on the R9 290 vrm t° and gpu performances.

About Vega and Apple, still it is not clear which is the agreement between both companies. And it is maybe this hidden agreement that driven the disastrous lunch. You need to wait that Apple release support with optimized drivers and OS to fully use Vega on Mac and as eGPU. This is maybe the reason you couldn't get the DP ports working as they should. Since this forum is mainly Apple based, it would be nice if someone poke Apple asking some information about.

The issues you’re experiencing in 10.13b are similar to what I encountered last fall when the RX 480 first came out. There was no official driver support for Polaris 10 cards atm but kext editing would allow them to work partially in 10.12b. OpenGL apps were crashing, only one port output, and no audio passthrough.

The drivers are still under development. eGPU functionality works with an RX Vega is a great sign Apple is going to support multiple GPUs for its official external graphics solution. Clamshell mode works intermittently is another good sign.

In my opinion, don’t buy an RX Vega now. Wait until the end of the year when the iMac Pro launches. The drivers will be mature by then and supply for these cards would be back to a normal level.

I fiddled around a bit and got Heaven to run with the enclosures (Got 2x 3GFX350 here, one with Vega64 Liquid and now third PSU LianLi 750W SFX-L PE-750B and one with the RX580 and the standard PSU) One box is used by me the other one by one of my colleges. Tested both with heaven haven (in fact I used his card the last two weeks till his box arrived and my card popped up) Both were tested using an Dell 24Inch 1920x1200 connected via DisplayPort. The RX580 achieves 36,2 fps average with 79 max and 8,9 min while. The Vega64 achieves 54,3 fps average with 111,9 max and 9,7 min while. Both with the Preset Custom, Quality:ULTRA, Tesselation: Extreme settings. 

 

And now on to your comments from earlier today:

I have big hopes in Vega and the possibility to spend the money now but not in some month due to time frame fixed funds. This is why I bought it now an had hopes it may work after the near perfect results I got with the RX580 using. Real plug and play without any bugs, even the system hangs and reboots after sleep got less using the eGPU. 

I followed your suggestion and replaced the PSU with a new one. So its now 750W ([email protected]) from Lian Li instead of 600W ([email protected]) from Silverstone at the same time this is an SFX-L PSU its about 30mm longer than the old one. Looking into this PSU I can see a bigger amount of caps inside so it could be that the rails are more stable due to more capacity. I'll try to check the exact voltage levels tomorrow. Under heavier load (last load digit bright) I still hear some hiss noise from the PSU but it is way more quiet than before. At the same time the frequency of this hiss noise occuring is about twice from the old one, so maybe its pulsing more frequently to deal with this load..?  This supply now got two dedicated 8 Pin connectors on board which both end in two 6+2 connectors. At the moment I got one of these 8Pin used maybe switching to use both 8 pin connectors at the PSU still could reduce this behavior through lower line impedance? on the other hand I thought about using some capacitors I got laying around to stabilize the 12V rail if necessary, still I am not sure if the PSU will be fine with additional capacity like this..... (I got some toys here in the office to poke around a bit if it would help?? [oscilloscope, power analyzer, logic analyzer])

Do you know if the pump is located on the PCB Board or integrated in the radiator? From noise I would say it is located on the Vega PCB it self. Together with the new PSU it got way more quiet. It spools up more smoothly and doesn't get that loud at all. But the heat being dissipated through this system is really enormous without getting that loud. During heaven the card got up to about 60-65 degrees, which seems quite ok for me?

Regarding apple and AMD/Vega my hopes still rely on apple using the kind of same "developer beta builds" to test their iMac units although reading their specs it looked to me like the Vega inside the iMac being an 56 model, which hopefully will not create those problems I saw with an RX570 not working at all within the enclosure while the other two at least showed up correctly.

Noise issues aside, is your setup now more stable with the bigger power supply? do you experience any hangs or crashes?

if I understood correctly, you are only using Vega64 with MacOS, not Bootcamp?

Here you got a picture of the liquid version of Vega, from GamerNexus review. As you can see the pump sit on top of the gpu, with his integrated copper plate (i hope) and fins where the liquid flow. The stuff on the right is the liquid tank to balance the liquid evaporation, since the card run quite hot. The blue stuff is the vrm watercooling plate, then on the bottom right you have the pump and fan header, with his PWM mini 4pin.

The power supply should feed directly the card with his PCI-e 2* 8pin, if you need to power the box pcb board, use another molex or whatsoever. But reserve the 2* 8pin to the gpu, to allow the psu to balance the load and focus delivering current on the PCI-e combined 12v rails, without middleman pcb that could raise the impedance as you said. There is no issue for the current to flow through the psu cables, but if 40A pass through something else before it could bring some issues. The power draw of Vega through the PCI-e is quite low, used only for the accessory vrm, so do not bother to feed too much the box pcb and PCI-e.

Normally you should not heard any clicking/switching sound from the psu, the psu should only get hotter and the fans should spin at higher rates to keep the psu cool. During heavy load there is a normal voltage drop from the 12.xV idle voltage. So it is normal if the rail drop bellow 12v, i think it is acceptable until it drop lower than 11.5V. But i have not a big experience into SFX psu, my small Lite-on 300Watt had also this switching sound, so i do not know if it is a normal feature.

I do not think it is worth touching the internal psu circuit, avoid if you can and if you have not the knowledge to do so. Because not only the caps and transistor are important, but also the main transformer is crucial for high current delivery. So it is better to keep the psu as it is. Just for the sake try with even powerful model if you have one under hand. Just for the science sake of testing different psu model, especially with a full desktop grade psu.

The heat dissipated is obviously humongous, especially on this liquid version. Your t° are quite good i would say, you can download GPU-Z to check both gpu and HBM memory t°, i think it got an update that work with Vega. Another tool used is WattTool, you can check for it on OCN forum, quite useful to downvolt the card to get better thermals for almost the same performances.

If you have a current clamp, by the way, clamp it to both 12v positive wires of the 2*8pin. Have fun reading how much current this baby take! ^^

Yup OSX only atm. Killed my BootCamp partition some days ago. It wasn’t playing that nice with those spontaneous reboots and having a windows partition which due to some weird stuff getting boot priority every time and having to shutdown...boot menu...OS X boot every time when this happened. Switched most productivity based applications to parallels (NX, VisualStudio with Realtime EtherCat extensions etc.)

Thx for the pic! Still Wimpzilla this layout looks a bit weird to me having the pump so close to the actual cooler where you want the best heat conduction possible between liquid (is it water in there?) and cooler core...

the Sonnet unit is wired quiet simple, it just uses the 24 pin ATX to power it self and the PCI-E slot, everything else gets connected directly from the PSU. In my case it is as i said a single 8 pin to 8 wire cable which splits into two 6+2 connectors on the opposite side. I just saw a video from jayztwocents (or how he is written correctly) where he used two of these cables instead of using both connectors, maybe it helps.. don’t know yet will try out tomorrow. you can see the cable with the old psu here

IMG 5657

My thoughts about the 12V rail where more in the sense of adding caps on these split of additional 6+2 connectors. This would place them quite close to the card itself, which from experience with XL4005 units should be far enough away from the switching circuit itself to not influence it too much.

those current clamps are really more like a rough guessing toy 😛 but to connect the good unit (WT1800 Yokogawa) i would have to splice the wires and this is not exactly what i would like to do 😉

Thanks I’ll check if those tools run natively on OSX(atm. I don’t have an bootcamp installation running), currently Beta 9 is installing (16 minutes left) maybe some stuff already changed through this update (at least it was a 3 GB download, which lets me hope that there where more than just cosmetic changes...)

Well you seems way more skilled than me in electronics if you can handle these nice toys. A basic current clamp, what is that! 😉 To use you awesome testing tool you could split a bit the cables from the 6+2pin connector, should not be a huge mess, at least if the probe is small enough.

I checked the Silver Stone 600Watt SFX have only one 6 pin output that split in 2 connectors as you said. The Lian-Li 750Watt have 2* 6pin output for the PCI-e like common desktop psu. The best for power hungry gpu is to have 2 separate PCI-e 6pin output from the psu and use them both to connect the gpu. If you can try also with a normal branded desktop psu to compare with the SFX one.

Adding capacitors to provide higher capacitance should solve in part the ripple issue, but in my opinion, the main transformer is the real culprit in these SFX psu, maybe it is smaller for the dimensions sake of the psu.

You are right the pump is on top of the cold plate, the pump do not like when the water t° goes above i would say 50/60°. That's why i think AMD engineers added a tank to ensure that the pump would not begin to overheat if the liquid would evaporate. It is a standard way to build AIO watercoolers, inside there is a mix of water and glycol to avoid corrosion and growth inside the loop. You can check on youtube how these AIO are build to get an idea. The ones used for the cpu are taller, so there is much space between the cold plate and the pump itself.

What could possibly help you with the air flow, is to put a push/pull fan configuration on the radiator, if the box board can host another fan without being too loud. I see you have the space to fit another fan to have both side of the radiator with airflow.

VEGA64 works fine with Dev Beta 9

Still listed as VEGA 10 Prototype but functionally fine.

Initial set of geekbenches seem to be slightly better scored.

This is a great news. Is is stable? Does games, FinalCut, valley works without graphic corruption and crash?

can't confirm that, my score was nearly spot on with beta 8 ( https://browser.geekbench.com/v4/compute/1067375) vs beta 9 ( https://browser.geekbench.com/v4/compute/1070547) but the internal values seem to vary quite much, some got worse quite a bit other improved more than 10%

i'am no real pro either in this field ^^ just a mechanical engineer with interest in power measurement (usually inverters, brushless motors, robots). The WT1800 probe sadly is a huge temperature controlled current shunt resistor mounted inside of the about 3 rack units high measurement unit ( http://tmi.yokogawa.com/de/products/digitale-leistungsanalysatoren/digitale-leistungsanalysatoren/wt1800-high-performance-power-analyzer/ ) nice for big stuff but pita for quick measurements...

I'll try the other way of connecting in a few minutes (will update here as soon as I have done this) 

Update: switched to the dual cable instead of the Y-splitter thing which was supplied with both psu units. Noise profile lowered again a bit, current switching noise is still there but seems to help a bit.

yep correctly those bearings, seals and stuff don't like this high temperatures that much. I googled a bit about those custom water loops, would be really nice to use something like a dual or tripple 120mm radiator instead of the small one and an decoupled pump but this would be more something for a "homebuilt" than an workstation in the office.

i'am a bit curious about doing this push pull configuration as long as the temperatures stay that low (60ish) I would prefer low noise instead of lower temps but way higher noise levels. Maybe I can organize that we buy an air-cooled which a transform into an custom liquid cooled thing but within this case I have no idea how to fit those without cutting out huge parts of the top plate and still having issues to mount everything (tubing inside but case needs to go on last from the top)

Well you seems way more skilled than me in electronics if you can handle these nice toys. A basic current clamp, what is that! 😉 To use you awesome testing tool you could split a bit the cables from the 6+2pin connector, should not be a huge mess, at least if the probe is small enough.

I checked the Silver Stone 600Watt SFX have only one 6 pin output that split in 2 connectors as you said. The Lian-Li 750Watt have 2* 6pin output for the PCI-e like common desktop psu. The best for power hungry gpu is to have 2 separate PCI-e 6pin output from the psu and use them both to connect the gpu. If you can try also with a normal branded desktop psu to compare with the SFX one.

Adding capacitors to provide higher capacitance should solve in part the ripple issue, but in my opinion, the main transformer is the real culprit in these SFX psu, maybe it is smaller for the dimensions sake of the psu.

You are right the pump is on top of the cold plate, the pump do not like when the water t° goes above i would say 50/60°. That's why i think AMD engineers added a tank to ensure that the pump would not begin to overheat if the liquid would evaporate. It is a standard way to build AIO watercoolers, inside there is a mix of water and glycol to avoid corrosion and growth inside the loop. You can check on youtube how these AIO are build to get an idea. The ones used for the cpu are taller, so there is much space between the cold plate and the pump itself.

What could possibly help you with the air flow, is to put a push/pull fan configuration on the radiator, if the box board can host another fan without being too loud. I see you have the space to fit another fan to have both side of the radiator with airflow.

i'am no real pro either in this field ^^ just a mechanical engineer with interest in power measurement (usually inverters, brushless motors, robots). The WT1800 probe sadly is a huge temperature controlled current shunt resistor mounted inside of the about 3 rack units high measurement unit ( http://tmi.yokogawa.com/de/products/digitale-leistungsanalysatoren/digitale-leistungsanalysatoren/wt1800-high-performance-power-analyzer/ ) nice for big stuff but pita for quick measurements...

I'll try the other way of connecting in a few minutes (will update here as soon as I have done this) 

Update: switched to the dual cable instead of the Y-splitter thing which was supplied with both psu units. Noise profile lowered again a bit, current switching noise is still there but seems to help a bit.

yep correctly those bearings, seals and stuff don't like this high temperatures that much. I googled a bit about those custom water loops, would be really nice to use something like a dual or tripple 120mm radiator instead of the small one and an decoupled pump but this would be more something for a "homebuilt" than an workstation in the office.

i'am a bit curious about doing this push pull configuration as long as the temperatures stay that low (60ish) I would prefer low noise instead of lower temps but way higher noise levels. Maybe I can organize that we buy an air-cooled which a transform into an custom liquid cooled thing but within this case I have no idea how to fit those without cutting out huge parts of the top plate and still having issues to mount everything (tubing inside but case needs to go on last from the top)

Ok so the issue is with AA, indeed your first bench was quite low considering I get higher score with RX 580, but this one without AA is pretty good.

as soon as Vega is stable on macOS I will upgrade!

thanks for the update, I really hope Vega drivers are ok with final High Sierra release

A single radiator is enough usually for the gpu alone. These are All In One systems, after that as you said, you enter into the world of homebuilt watercooling loops, where the pump/tank is a separate unit inside the system. What sit on the cpu/gpu are only the copper block where the liquid flow. If you want to build a watercooling for your workstation let me know, but usually you do that because you want a nice overclock on your cpu/gpu or run the workstation nearly silent at stock. Again i would advice homebuilt watercooling only on full desktop workstation, not on portables solutions.

As always i point out all the DIY mods one can apply to the build, but i think if you are not an enthusiast that want to overclock the card, the actual airflow is enough. The watercooled vega have lower throttling gpu t°, so if you go over 70° at this point the push/pull is a solution, as increasing the fan/pump speed. To keep the gpu full throttle the gpu/HBM t° should not exceed 70° if i remember well.

So after powering the gpu decently, now you have to wait the drivers and OS updates. If you have some spare time test under windows, running the card full throttle to assess that the whole setup is indeed stable. You should not have trouble letting the eGPU setup computing, but always keep eyes on t°, especially with closed enclosure and long computing runs, to alleviate the power/t° pressure on the psu.

Last thing is to ask @Goalque if he had the same transistor switching noise when the psu is under high loads, maybe is a normal features on these small SFX psu.

Thanks for your help guys. I toyed a bit around with the two units, the RX580 really runs completely smooth. Tried running "Borderlands 2" which tends to crash on the Vega shortly after Login, "BioShock 2" boots up but has a lot of texture glitches and boxed graphics instead of rounded "drops"

Temperatures stayed within the 60 to 65 degree range all the time with the Vega64 (but I am still on the "softer bios setting"

 

If there is something I shall test let me know but somehow e-mail notification about new posts is not working...(and I can't save an email address within the profile here)

I have the 2016 MBP 15" custom... I just purchased the XFX Radeon Vega RX 64 and the Mantiz-02 is arriving in two days... Other then the Ethernet Driver that needs to be installed, this setup should be plug n play under High Sierra Public Beta 9?

What apps are you guys using with this setup that seem to be working well?

Wow!

I’m considering picking a 64 up for gaming and other stuff. My setup is an MBP 2016 and a Node. I have a RX 480 which works well but kinda sucks at 4K.

I'm excited for my setup... Hopefully it isn't too much work to get this baby going... This MBP GPU sure does struggle.

Sorry to say that but Veg 64 seems too much for eGPU PSU at least for now without software optimization. It is better to stay with Vega 56

Yeah, I tried running High Sierra from the internal SSD of the Mantiz... The system recognized the RX 64, but the system kept freezing... The only time it didn't freeze is when I was running GPU tests... Would the PCU cause the system to freeze like that or the drivers?

So is it safe to say we need to hold off on the Vega 64 right now? I was planning to sell my 1080ti as it's borderline useless for Mac pro apps right now (e.g. Final Cut keeps crashing etc.) and purchase a Vega64... but now I'm having second thoughts.

@nelga which eGPU enclosure are you using? If the PSU is not 600W+, the RX Vega 56 is a better choice.

I'm trying to find out what eGPU to use with my iMac 5k (Late 2014) for rendering/playback of apps like DaVinci Resolve and FCPX. Would this be a RX Vega 56 or a GTX1080? I am currently running OSX 10.12.6. Thank you.

Hey I'm using the Mantiz Venus. Do you know if this is only bottleneck or cause of issues?

Do you know what the performance difference between the 64 and 56 in this enclosure?

Thanks for your help!!

The latest betas seem to have fixed some issues. Geekbench up from 150k ish to late 180s 🙂 It's comparible with all scores in Windows now, including Cinebench (up from 120 to 155)

Also the GPU crashes have gone from Chrome, Archicad etc. However, there seems to be a lot of GPU activity at idle and it's running hotter. Can anyone else confirm this?

I fiddled around a bit and got Heaven to run with the enclosures (Got 2x 3GFX350 here, one with Vega64 Liquid and now third PSU LianLi 750W SFX-L PE-750B and one with the RX580 and the standard PSU) One box is used by me the other one by one of my colleges. Tested both with heaven haven (in fact I used his card the last two weeks till his box arrived and my card popped up) Both were tested using an Dell 24Inch 1920x1200 connected via DisplayPort. The RX580 achieves 36,2 fps average with 79 max and 8,9 min while. The Vega64 achieves 54,3 fps average with 111,9 max and 9,7 min while. Both with the Preset Custom, Quality:ULTRA, Tesselation: Extreme settings. 

 

And now on to your comments from earlier today:

I have big hopes in Vega and the possibility to spend the money now but not in some month due to time frame fixed funds. This is why I bought it now an had hopes it may work after the near perfect results I got with the RX580 using. Real plug and play without any bugs, even the system hangs and reboots after sleep got less using the eGPU. 

I followed your suggestion and replaced the PSU with a new one. So its now 750W ([email protected]) from Lian Li instead of 600W ([email protected]) from Silverstone at the same time this is an SFX-L PSU its about 30mm longer than the old one. Looking into this PSU I can see a bigger amount of caps inside so it could be that the rails are more stable due to more capacity. I'll try to check the exact voltage levels tomorrow. Under heavier load (last load digit bright) I still hear some hiss noise from the PSU but it is way more quiet than before. At the same time the frequency of this hiss noise occuring is about twice from the old one, so maybe its pulsing more frequently to deal with this load..?  This supply now got two dedicated 8 Pin connectors on board which both end in two 6+2 connectors. At the moment I got one of these 8Pin used maybe switching to use both 8 pin connectors at the PSU still could reduce this behavior through lower line impedance? on the other hand I thought about using some capacitors I got laying around to stabilize the 12V rail if necessary, still I am not sure if the PSU will be fine with additional capacity like this..... (I got some toys here in the office to poke around a bit if it would help?? [oscilloscope, power analyzer, logic analyzer])

Do you know if the pump is located on the PCB Board or integrated in the radiator? From noise I would say it is located on the Vega PCB it self. Together with the new PSU it got way more quiet. It spools up more smoothly and doesn't get that loud at all. But the heat being dissipated through this system is really enormous without getting that loud. During heaven the card got up to about 60-65 degrees, which seems quite ok for me?

Regarding apple and AMD/Vega my hopes still rely on apple using the kind of same "developer beta builds" to test their iMac units although reading their specs it looked to me like the Vega inside the iMac being an 56 model, which hopefully will not create those problems I saw with an RX570 not working at all within the enclosure while the other two at least showed up correctly. 

Does the SFX-L fits good into the Sonnet Breakaway? i want to use a Vega Frontier Edition Liquid but i'm not sure what is the best choose for a quiet PSU.
