Does this issue with the Ethernet/USB appear for you only when you have heavy GPU load? Asking as for me (2017 15" Spectre) the wired ethernet is considerably more responsive than WiFi.

Also, are you using the Omen Accelerator app (and did you change perhaps any network settings there)?

WiFi:

It is mostly happening during heavy GPU load. Which is a problem playing, for example, Pro Evolution Soccer 2018 online. Ethernet becomes laggy and I get kicked off, affecting my online trust rating! Also sound crackling on DAC. I did check the settings in the network accelerator part of the Omen software. I tried off, custom & auto. When custom the game was set to "High".

Could the high quality 40 Gbps 2m active cable I bought, be a contributor?

Thanks for replying.

Still no reply on HP support forums but the workaround, works.

Bump.

The powered USB hub + TB3 Ethernet adapter cable is the workaround. Not as elegant as the advert though. I even tried different TB3 cables. Stock and a 2m active cable - same issue.

I half suspect the 4K display is saturating the TB3 controller and/or using GPU overclocking utils is causing the port lag. I was hopping some HP boffin (ie beyond level 1)  would reply here so I don't need invest any more time or money.

Certainly not working as advertised but I'm still happy.

Please see my egpu fix post - it's common.

 

Let me know if that fixes your issue

Thanks for taking the time... by fix you mean the below I assume? Been there already and set USB suspend to disabled. Wouldn't explain Ethernet lag though.. I am at work right now but will default power plan to High and disable USB suspend exactly as per your instructions. It would be nice to return the USB hub and go back to the elegant one cable solution. I still feel 4K+ 4 USB ports + Ethernet is too much for TB3 but I hope I'm wrong. 

Select High Performance for your NUC

Select Change Plan Setting

Select Change advanced power settings

Select the + sign next to USB settings

Select the + sign next to USB selective suspend setting

Select Setting: Enabled, change to DISABLED

That should fix your issue, please confirm that it does.

To avoid any confusion - I'm not a support engineer (L1 or other 🙂 ). I work on AR/VR/3D scanning and just find the Accelerator extremely useful for that area - and, well, gaming, too. The Omen devices fall under the higher (specialist) support tiers just like the Spectre, so I would encourage everyone to use the phone line in case of any difficulties (the HP support forum is more of a community/informal approach). If they can't answer straight-away they will call you back, no email-bouncing or extensive hold-call sessions etc - it's one of the perks of having Omen hardware.

No, I'm quoting myself from the HP support forums, in italics. Really appreciate your help. I am a heritage HP & HPE employee (now Micro Focus) to boot 😉

Will be resetting my power profile and only changing USB suspend settings when I get home.. sadly a few hours to go yet.

Hi guys, based on this experience  https://egpu.io/forums/builds/brief-experience-with-the-razer-blade-stealth-and-devil-box/

I think it will work.

 

On other hand I just ordered HP OMEN Accelerator for myself to use it with my new Razer Blade Stealth. Give me a week to receive it, unpack and test. I will give you more feedback for sure:)

Hi guys, it took me more time than I awaited but finally I deployed my RBS2017 together with HP OMEN Accelerator.

1. Power delivery is perfect = 65wats as should be, battery recharge is faster than original charger (which is 45W).

2. RBS2017 has 4 lines to PCIE and proper thunderbolt driver. My D2H is 2600MiB/s with nVidia 980.

3. RBS2017 has all issues (mouse flickers, USB DAC crackling) with all USBs as mentioned above by @Gordon Fitzsimmons. To retest this I connected OMEN to colleagues Alienware 15R3 and there were no issues. Based on this, it looks more than the issue with something inside of our ultrabooks and not with the OMEN itself...

Did that work?  Ethernet is also over USB so that could fix both issues...

Make sure:
a) that you fully connected the SATA plug (I know it's trivial, but...)
b) that you haven't accidentally damaged/pulled the ribbon cable connecting to the Omen motherboard

 

Sure enough. That was the problem. It must have been caught on something in previous attempts to fix. I obviously would have noticed the cable not attached earlier. God damn that thing is flimsy. I'll have to take the whole thing apart to fix it as well. It looks like every screw to get the shell apart and power box out.

Commenting on the Ethernet issues, I have noticed vastly improved game play in Rocket League on my Spectre 360 since going to wired ethernet. 

this goes for all eGPU's., but the negative of this set up is everything comes thru 1 flimsy cable, if jostled it causes computer freeze and I'm rebooting. I feel like I'm carrying a baby over flames trying to play on my couch.

Hello everyone,

I have a HP Spectre x360 Convertible 13-ac0XX (Mid 2017) too and also an HP Accelerator Enclosure. I'm not using the wired ethernet port at all, but only the usb ports for mouse, keyboard and a usb headset and can confirm these disconnects and stutterings when under load. It is enough to just "upgrade your character within the main menu in Dead by Daylight" so get these problems. When I connect the devices to an USB-Hub directly to the notebook, no problems at all.

Deactivating the usb suspend to sleep option within the power plan profile did not solve the problem. Any other ideas?

//Update:
Updated from BIOS F31 to F34. Problem still persist.

Thanks for all the comments chaps. Only had to time to alter the working USB hub + TB3 Ethernet config tonight. I have tried resetting the power profile to high and disabling USB suspend. I have also jiggled the SATA cable and made sure its in place. Looks very sensitive at the mobo end so didn't want to completely unplug and plug in.

My conclusion is that this box is not up to full USB port population + Ethernet on its own. The stuttering still happens - though not as badly - when playing a game at 1440p. I don't have confidence in the intended single TB3 cable solution. I'm bad enough at PES as it is, so don't want to get chucked off games on top of this, due to high latency.

Since I got £100 off the Omen Accelerator I am not too fussed. It works perfectly with the USB hub + TB3 Ethernet and I have an extra charging port now. Would love to know the root cause though. Don't think my old colleagues at HP Inc have followed up my support post. Shame. 

Cheers

/after thought: loose cable, we are talking about the SATA HDD cable? Not some other cable I haven't seen?

By the way ... the ethernet card in my hp omen accelerator is recognized as a cdrom and not as a network card. I deactivated the card, because the system tries to open the "empty drive"regular and prompts me with a "cant be opened"-Message.

Hi all,

So I'm considering finally getting myself an eGPU enclosure from my 2016 HP ZBook Studio G3 (Xeon E3-1505M, Intel graphics + Nvidia Quadro m1000m, 512GB NVMe M.2 boot drive + 1TB SATA M.2 Drive), and would like some input as to whether to go with the Omen Accelerator or a Node.

Currently, I'm using the ZBook (at home) with an HP 150W Thunderbolt 3 Dock, with my monitor (Asus PB278-Q), Ethernet, and peripherals all connect to the dock without issues, and with a 10TB NAS on my home network.

My question is whether there is any benefit to spending the additional ~$30 on the Omen compared to the Node (to be used with an Asus GTX980 Strix for the foreseeable future) as far as compatibility, stability, and, most of all, silence goes?

Also, would daisy-chaining which ever enclosure I end up going with after the TB3 dock degrade performance in any way? The Thunderbolt Bridge on the ZBook is x4, so at least the full bandwidth is available...

Thanks-in-advance, and sorry if I posted this in the wrong forum...

Cheers,

-4

I had this issue too, the cdrom bit is a red herring - locate the random USB Mass Storage device in Device Manager and uninstall that - that should give it a kick and recognise it properly.

Thanks, that helped. Uninstalled the "USB Mass Storage Device" under the "USB-Devices" tree in Device Manager and the wrongly cdrom device, clicked redetect and now I have my ethernet card. 🙂

Another update to the usb ports on the enclosure. I attached my USB-C Hub to the omen and attached there to usb devices (mouse & keyboard). With that setup I'm not getting any lags or stuttering. Will try to connect the usb headset and the xbox 360 wireless receiver to it to test devices with more power consumption. But maybe the problem only persists to the usb a ports.

I never had the two side-by-side, but I had the strong impression that (especially under load) the Node was considerably louder. YMMV. The construction of the Omen makes it easier to customize for a super-silent option (as it uses standard power supply, a 120mm fan and a larger case).

As for daisy chaining - yes, there will be consequences. TB3 is not a zero-lag endless bandwidth subspace channel as sometimes people perceive it to be 🙂 I'm not sure on the exact level of the performance impact (will depend on your use-cases, too), but latency will certainly suffer which is never a good thing for the GPU. I previously used a HP TB3 dock but have switched to the Omen Accelerator and effectively using it as a dock (with a combination of a powered USB3 hub).

As I said before = this issue is probably related to the performance of the laptop too. When I switched my RBS to heavy-duty/heavy performance Alienware 15R3 there were no problems with USBs at all.

I'm definitely aware that there will be some performance loss due to daisy-chaining, but with my current setup (laptop kept closed on a shelf under my desk with only the dock cable plugged in) I'm kind of dependent on the power button of the TB3 dock... 😛

As for the potential performance loss if used together with the dock, though, would it be comparable to using just an enclosure with built-in USB/Ethernet ports, like the Omen or Mantiz Venus, as I've read in a few places that enclosures with additional ports preform slightly worse, and you lose more, the more ports you use, or would you lose even more bandwidth just because it's a separate device?

If you want top non-laggy performance with this box go with a USB hub and main device Ethernet. x360 mid 2017 + Omen Accel + 1060 here. Excellent results. I wouldn't touch the Omen's ports with a barge pole for gaming.

Well then would the Sonnet Breakaway be a good option? It doesn't have any of the extra ports like the Omen, which are clearly just a waste, but seems to have better cooling (120mm fan) and a 350W SFX power supply which could (theoretically) be easily swapped out by hand for something like a 550W if you wanted to chuck a more power-hungry GPU in there.

FWIW The Omen also has a 120mm fan, and a decent full-size PSU will always be at an advantage in terms of cooling, power and, consequently, noise.

Another thing to consider is price = In Czech/Slovak republic is OMEN at 250EUR, SONNET at 350EUR...

@kUMters: The price difference is actually the opposite here. Right now, on Amazon, the Omen is selling for almost $100 more than the Sonnet.

 

@4chip4: Does the Omen have a full-sized ATX PSU, or is it also SFX? I find it quite odd that even though the Omen has a PSU rated at 150W more than the Sonnet, they both only support a 300W GPU... Does an Ethernet port, one hard drive, and a few USBs really require that much power?

It does look like the Omen has a slightly higher-quality PSU, though, with an 80+ Bronze rating as opposed to just 80+, though at the current price difference between the two you could get a 450W 80+ Gold SFX PSU from Corsair or Silverstone for the Sonnet and still cost less than the Omen.

 

Again, I'm just making assumptions based on what I've read/can see and have no personal experience, so suggestions are all welcome!

Difference is that a bigget PSU will also allow for USB-PD to be provided to the laptop (up to ~60w?) in addition to running a 300W GPU. It's very important if you have only one USB-C port and that's also the charging port.

The Omen has a full-size ATX 500W PSU ( see my previous post for details). The Omen has a max of 60W power-over-TB3, 5 USB ports + hard drive, so it can add up. The GPU rail itself is 400+W so you can theoretically go over 300W if your load is otherwise not high, but having a bit of headroom is always a good thing stability-wise (the 300W is a "no matter what, 300W will work" as opposed to "430W might work, but then you must not use features A B or C").

Now, if you DO want power-delivery, and you need to go considerably over 300W, it's still going to be easier/cheaper to get a bigger ATX PSU than SFX, that's the upside of the box being so big. If you don't need/use power-delivery, there is probably a bit of headroom in there for a stronger GPU (though then the TB3 link might prove a bigger limitation).

Thanks!

Since the ZBook Studio has a dedicated DC jack (it's charge/TB3 dock is 150W), I'm not sure it even supports USB-PD, so that's not an issue for me at all.

I guess right now it's really a decision between the Omen and the Sonnet, and considering that the Omen uses a full ATX PSU, I'm now seriously leaning in that direction... If only it wasn't so damned large... And out of stock everywhere... 😛

Hi guys,

Are there limitation on which GTX 1070 you can put on the Omen accelerator?

Just ordered mine and an HP Spectre so need to order a graphics card...

Any input?

The only concern is the cooler width. If the cooler is double-slot, the GPU should fit just fine.

Thanks you for reply

So the ASUS STRIX-GTX1070-O8G-Gaming Nvidia Geforce GTX 1070 Graphics Card Should fit inside the omen accelerator?

From Asus website:
Note
To have the best cooling performance, ASUS STRIX-GTX1070-O8G-GAMING extends the fansink to 2 slots. Please double check you Chassis and Motherboard dimension prior to purchase to make sure it fits in your system!

Should fit fine. As @itsage says, it's the 3-4 slot ones (usually liquid/hybrid cooled xx80 cards) that wouldn't fit. I think dual slot 1070s are almost the "default" cards the Omen Accelerator is shown with (I believe the HP "recommended" setups are actually 1060 and 1070 cards).

The Omen has a full-size ATX 500W PSU ( see my previous post for details). The Omen has a max of 60W power-over-TB3, 5 USB ports + hard drive, so it can add up. The GPU rail itself is 400+W so you can theoretically go over 300W if your load is otherwise not high, but having a bit of headroom is always a good thing stability-wise (the 300W is a "no matter what, 300W will work" as opposed to "430W might work, but then you must not use features A B or C").

Now, if you DO want power-delivery, and you need to go considerably over 300W, it's still going to be easier/cheaper to get a bigger ATX PSU than SFX, that's the upside of the box being so big. If you don't need/use power-delivery, there is probably a bit of headroom in there for a stronger GPU (though then the TB3 link might prove a bigger limitation).

Have a closer look at Omen's PSU. GPU does not get 400W - there multiple 12V rails... 🙁

I’m close to completing the OMEN Accelerator review. The PSU is its weak link. No other Thunderbolt 3 eGPU enclosure has an ATX power supply. The multi-rail 12V is capped at 420W. Power Delivery at 60W and other overheads, 350W to the GPU would be best case scenario.

Thanks for investigating this. 1170 will be the next upgrade. As long as I can play PES in 4K i don't mind. Stuck at 1440p with the 1060 currently.

What about the ports itsage? Is it me, my x360 or HP Inc?
