For Vega64/56: please try the following workaround:

- Open Wattman

- Adjust manually clocks and voltages for P7 (highest performance state) to P6 values (1538MHz, 1.15V - or whatever values are for P6 on your card)

- double check that P6=P7

- click "Apply"

By doing so you will lose few percent of performance (not noticeable in real world applications), but it reduces peak power/max power

If you are still unable to achieve 100% stability under load, play with Power Limit settings (reduce the Power Limit by 10% at a time - and dont forget to click apply!)

This is a temporary workaround; work on Vega optimization is in progress.

eGFX vendors like Mantiz and others should directly work with AMD to ensure that their enclosures will work with upcoming AMD drivers

So it is not advised to use a Vega 64 with the PSU that comes with the Venus? What if you undervolt the Vega 64? Would it still spike above the maximum capacity of the PSU?

according to the high peak current reach to 650W, we don't suggest to use Vega 64. Actually None of eGPU can drive Vega 64 for the time being unless, we increase to 750W PSU for that. ( Cost )

Do you plan to offer a user upgradeable power supply that we can swap out with out voiding warranty support?

we work with AMD directly, we even have beta driver ( None WHQL one ) and it is pity that the peak current is still high.

I wish I could, but any changes of the HW will impact to the Intel Cert. it is a very long and costly process...

Yes, I realize this, but this occurs when the Vega 64 is on stock settings and on load, no? What if it would be undervolted, would it still reach 650W?

Can someone enlighten me on this subject? I'm currently in doubt whether I should go for a 56 or 64.

56. 

or wait for any eGPU vendor use their POWER supply  to be 650-700W.

Guys and when people want using Venus with Vega64, what buy second PSU (for example seasonic 1000w) and this second PSU connect to in house into electric and connect only into graphic card on two 8pins? This will not work?

LAPTOP = HP Spectre x360 13 Dark Ash Silver (i7-8565U, 16GB DDR4, 512GB SSD)
EGPU = Mantiz Venus MZ-02 Space Grey + PSU Corsair SF600 600W 80 Plus Gold
GPU = PowerColor AMD Radeon RX Vega 64 8GB HBM2
DISPLAY = Samsung C27FG73 | ROUTER = NETGEAR Nighthawk X4S R7800
KEYBOARD = Logitech G810 Orion Spectrum | MOUSE = Logitech G305 Recoil Black
CHAIR = DXRacer Racing OH/RV001/N
PHONE = OnePlus 6T MidnightBlack (8GB LPDDR4X, 256GB UFS2.1)

@PepeCZ, DO NOT run the eGPU with 2 PSUs! You can use an ATX 1000W to power both the TB3 board (24-pin plug) and the RX Vega 2x 8-pin plugs. Don't connect anything to the stock SFX PSU of the Mantiz Venus if you are using a different PSU.

Correct! One larger power supply will solve the problem; definitely no need to use 2 power supplies.

Looks interesting (albeit pricey!) It is rated at 66A on single 12V rail (me mucho likes single rail power supplies :), and it seems to be the most powerful SFX PSU which could be also used for upgrades on Sonnet 350W and Akitio (all use SFX).

What I am not sure is the peak current (on 12V rail) - not specified on their website. Well, Amazon does have return policy - give it a try.

When AMD does declare official XConnect support for Vega (and trust me guys, this will happen!), that excess power supply capacity will let you to play with power limits and clocks on your Vega, squeezing every drop of performance

The limits look like they are the following, I would love to test this setup do you have a Vega 64 you would be willing to donate for testing 🙂 in all seriousness here is the limits on that power supply - not a bad deal I think.

Over-power protection
The power supply will be shutdown and latch off when output power over 110% ~ 160% of rated DC output.

Over current protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V outputs from exceeding the values shown in the following Table. If the current limits are exceeded the power supply shall shutdown and latch off.

Voltage

Over Current Limit (Iout limit)

+12V

70A minimum; 90A maximum

+5V

20A minimum; 45A maximum

+3.3V

20A minimum; 45A maximum

this is the issue, 5V 20A Min and 3.3V Min 20A, this is normal in a Motherboard, we are not a Motherboard, we sometimes 5V & 3.3V are Zero, which will also cause the PSU the " Unbalance Situation" ( 12V too high and 5V zero ) PSU will go to the protection mode which means : Shut down .

2nd, A PSU swap is not recommended, because it is not fully tested, including the safety, stability and performance. ( On/off, Power Delivery, Current stability....DC-DC....etc ) so, change it with your own risk. Currently we only suggest to use 56 in Vega series.

from the spec point of view, 12V Min 0.15  66A seems Okay for Vega 64 but Min 0.15 maybe still too long for Vega....

2nd, 5V Min 20A , Mantiz Venus Mainboard will not giving 5V at least 20A, we can be zero A and same as 3.3V, so the PSU may be shot down.

5v min == 0.2

3.3v min == 0.1

I personally do not have a Vega (too much price gouging going on to get one) I have a 1080TI however I was looking at the Vega due to OSX High Sierra support and nVidia not having support for egpu's in High Sierra currently*

 

*I understand High Sierra is still beta however based on nVidia's time table in the past on releasing drivers "I" do not expect anytime this year for the 1080TI to be supported natively in High Sierra with out hacks. (Nothing wrong with hacks just not for my production work computer)

@MyMantiz_John,

I don't know if this will help, but I would like to share with you that I just recently acquired an new iMac w/ RX 580 8GB. and because I did not sell yet the Vega 64, I decided to give it a try with the iMac/Mantiz and I got surprised that I was able to play for hours without any problems at full settings @ 4K the same games that previously were shooting down the Mantiz with the MacBook Pro (late 2016). So, why same hardware works flawless with the iMac and not with the MacBook Pro, it is clear that we are missing something, right?

it is so nice that your iMac work well with Mantiz Venus. Enjoy it....It perhaps that iMac ( I guess ) there's no iGPU, but only dGPU. 

also, Itsage did a very useful steps to guide PPL in MBP 15 & 13" by Using rEFIND & Apple_set_oc.efi. I had tested it with many cards including the Vega, playing games, benchmarking, it is very stable, even accurate the internal display. So, MBP I will say there's no issue to work with Mantiz at all, we just need to have patience to comply the processes.

@Mymantiz_John,

 

Mantiz Venus is a solid eGPU to work with MBP. I tested win10/Macosx (using ITSage guide) with GTX 960, RX 480 and GTX 1080 and all good and the only exception so far is the Vega 64. But, my question is still open: why the Vega64 is not shutting down the Mantiz Venus when you use it with the iMac?. I brought this more to see if this can help to somebody in this community to figure it out and make the perfect combination to work sooner(Vega64/Mantiz Venus/MBP)

One thing I noticed with my setup is that Vega Rx 64 works great if the MacBook is fully charged. Try to use the MacBook charger before connecting Venus in case the battery is not at 100%

My guess is when there's no active power delivery from the enclosure to the host, the Mantiz Venus' 550W PSU can feed the majority of its juice to the RX Vega 64.

@AngelRC,

Thanks for your advice. One of my hypothesis (in my lacking knowledge world) was that the thunderbolt 3 on the iMac was not using the power capability of the Mantiz, so it can dispose more watts for the GPU, but then I realized that the PSU should keep independents between powering GPU and charging MBP.

Are you on High Sierra or Sierra?

Are you using Internal or External bootcamp?

Which version of win10?

Thanks

I am not sure who are you working with - please PM me directly

Our ODM works directly with AMD, I should not say " we " as above.

What we heard  the driver modification is ongoing. We hope that AMD can solve the high power consumption &  peak current  issue by no hurting performance way!!!. Cross Finger!!

I tried High Sierra with a Mac Mini 2012 and a Thunderbolt 3 Adaptor running Vega 64 on Venus with  3 4K displays + HTC Vive with no issues. I was able to calibrate de room for Vive with Steam Room Calibration. At this moment I couldn't go further than that. But The important thing is that the HTC Vive basic software + hardware works event with 3 4K displays active... This is terrific counting that Mac Mini 2012 has Thunderbolt 1!  

For the MacBook Pro 2016 I'm using W10 Pro Creator Update running in a 150GB partition located in the internal SSD. Venus connected to bottom left port. Again running 3 4K + HTC Vive..

I believe that with the current drivers for macOS and Windows we are not squezing all the juice of Vega 64.. 2 cents that we will see an increase of performance with mature drivers and optimised software/games for High Sierra and Win 10!

I guess everyone is waiting for the firmware 🙁 Would that be a certification problem? If so you can just call it beta testing and make it available for us thru pm @Mymantiz_John

FW had been released! Please check our blog post:

@zwubel, your before performance statically allocated 5Gbps of the 32Gbps input to the TB3 controller for the peripheral devices (SATA, USB 3.1 G1, LAN). So you lost 15.6% of your bandwidth (5/32*100).  

Your after (new Mantiz Venus firmware) sees you recoup that 15.6% of bandwidth and are now getting full 16Gbps-TB3 H2D bandwidth. This is  64% the performance of 32Gbps-TB3 as shown here.  It's more than the half we expect. Of course a 4-lane TB3 system would let you recoup the remaining bandwidth.

Regaining bandwidth is good, but how about USB device functionality? Does USB  work well when GPU is loaded?

Yes, Well. Tested. And also if anyone is suffering from the Full Bandwidth, we had the FW to be H2D 16xxMiB/s to fix it. That's from Intel's best suggestion so far. 

it is about to fix the CUDA H2D, AMD anything related?

@nando4: thanks for the explanation!

@all: does anyone also have problems with DXVA2 video playback? This has nothing to do with the firmware upgrade, it's a preexisting condition if you will. I have spent a lot of time trying to figure out why Media Player Classic Home Cinema (MPC HC) with madVR does not seem to yield anywhere near the same performance as it used to (same monitor, same GPU: nVidia GTX 960). I thought it was (at least in part) related to the slower 2-lane TB3 connection, but now I just noticed that neither MPC HC nor the VLC player are able to use any video hardware decoding from my GTX 960 (they both either crash or freeze when it's used). I'm just wondering whether anyone else uses the Mantiz Venus with an nVidia GPU to decode videos with or without having problems. When I disconnect the Venus and use the iGPU in my i7-7500u, everything works well. If noone is experiencing these issues, could someone maybe just try it with VLC? All you need to do is make sure that under Tools -> Preferences -> Input & Codecs -> Use GPU acceleration is set to DXVA. If I set it like this and open a file, VLC immediately crashes. If I set it to off, the video plays fine (albeit with high CPU utilization, of course). Any help would be appreciated!

Could you try Potplayer to see this DXVA?
