nMP - HP Omen Accelerator - TB3/TB2 adapter - won't start up

Hi all,

I just got a HP Omen Accelerator which won't power up when connected to my nMP.

Connected to another Windows laptop with native TB3 interface everything works well. Device turns on, card is powered up and is recognized by Windows, etc. etc., as soon as the TB3 cable is attached.

Connected to my nMP however, nothing happens - looks like it is not initiated properly. Neither on most current High Sierra, nor on Windows 10 via external hard-drive.

Setup: Mac Pro 2013, 32gb, HP Omen Accelerator, old AMD card (will be replaced by a new one soon), Thunderbolt 2 cable, Apple TB3 TB2 adapter ( MMEL2ZM/A)

How can I power up the eGPU with my nMP?

Any advice is much appreciated!

Thanks

Christian

Are you plugged into bus 0?  The 2 immediately above the HDMI port.

I had the same problem but with the Omen Accelerator and a Macbook late 2014 connected with the Apple Thunderbolt 2<->3 Adapter.

The Omen Accelerator never turned on no matter how it was connected or which cables where used.

I assume the Omen I got was delivered with an older firmware, not the latest 25.25. But I have no access to a Windows computer with TB3 ports at the moment to verify this.

Have you checked the firmware of your Omen on the Windows Laptop?

Hi Flint, yes I am. None of the six ports worked out...

Thanks

Yes, successfully updated the firmware yesterday via a TB3 notebook.

Also powered the nMP off for 20 seconds, did a NVRAM / PRAM reset.

Tried an NVIDIA 1070 today

Didn't help.

Any further ideas? 

Cheers

What does the Thunderbolt tree in System Information look like? Does the light in front of the OMEN Accelerator power on when connected?

It says no device connected. 

The eGPU case is not powered on. Red light stays off. 

Unless I connect it to a native TB3 port, then the whole box starts up.

Could it be that the Omen accelerator needs too much power over the Thunderbolt port to be activated, due to the vast amount of interfaces it provides (eg. network, 4x USB)?

Apple states on their Thunderbolt information site, that the Apple Thunderbolt 3<->2 adapter only supports one powered Thunderbolt 2 device on a USB-C equipped Mac.

All working Omen Accelerator builds I have seen to date uses a native TB3 connection, or am I wrong?

If possible, I’d say check the Thunderbolt 2 cable and Apple TB3-to-TB2 adapter to make sure they both work.

Thunderbolt 2 cable - tested - works

MMEL2ZM/A adapter - tested - unsuccessful:

- Booted the nMP in target disk mode and connected via adapter & tb2 cable to windows laptop. Adapter is found in device manager, but no disk is shown in disk manager. After some time windows shows "Unknown USB Device (Port Reset Failed)"

- Connected laptop to Sonnet Echo Express SE II box via adapter & tb2 cable. Device does not power up

Once I connect the nMP to the Sonnet box tb2 to tb2 the Sonnet powers up.

I did disconnect - wait - reconnect a few times of course to test.

Something related to the adapter, good guess itsage. Or a windows driver issue. The adapter is brand new. Somehow I feel this is a design / protocol issue, not a necessarily a hw defect. Unfortunately, I do not have a second adapter to test...

Cheers

Christian

Edit: Also, connecting to an LG 34'' TB display did not work. Though the right source is selected the display still shows "no signal".

I know it *CAN* work with the TB2 to TB3 adapter, I have an Omen Accelerator plugged into a Macbook Air right now via the TB2 adapter. I have noted that it won't BOOT that way, I have to leave it unplugged and plug it in once the Apple logo shows.

Punk, I did try what you described with another MBP with Thunderbolt 1. Behaves the same as the nMP in every test.

But also: Once connected the MBP to the LG34“ TB display via TB cable it did not work. So maybe the LG display is not much of an indicator for the underlying issue. 

 

Slowly running out of options. I ordered another tb2/3 adapter just do make sure...

A few news: Switched to the Sonnet Breakaway box. Everything else stayed the same. The powers on and the card gets detected. Running into a different issue (different thread) here, but my takeaways is: The HP Omen Accelerator just does not work on TB2.

Thanks for your help so far!

Could you please check the firmware you have on Omen Accelerator

I have troubles using it with adapter

It shows as 25.25 in System Information.

So you are saying that the Omen Accelerator can work with a TB3->TB2 for an older mac?
You just plug it in after the system boots?

I have the same problem. Omen accelerator does not start. It just flashes and then stops. I tried with MacBook Pro 2015 High Sierra 10.13.2 and MacBook Air mid 2012 High Sierra 10.13.3 through TB3 to TB2. I installed NVIDIA web driver and NVDAEGPUSupport. The System Information says "No device connected".

I also tried a boot process with FileVault enabled and disabled using a guide in the forum. But none of them works.

I also tried with a paperclip to start Omen accelerator and repeated the boot process, but I have no luck 🙁

@punk.kaos: could you describe your process and your system (macOS version, drivers, cables...)?

Yep, I'm using it on a 13in 2017 Macbook air no problem at all. I'm typing this on it right now!

I plugin the minute I see the apple logo, it starts up with the login screen on the external monitor and I go to town.

I have the Omen on a TB2/TB3 adapter plugged into the only TB2 port on the 2017 Macbook air

I've activated it two ways. Usually I plug in right as I see the apple logo at boot. Or I can plug in after boot, and log out after the "EGPU detected" box pops up. and log back in.

My cable is an Apple branded TB2 cable. I'm running 10.13.3, I have automate-egpu.kext installed because I have a Radeon RX560 in the enclosure which isn't natively supported. 

Other than that I didn't have to do anything special. It just worked. 

 

I WILL note, just incase you're on the new beta, the RX560 comes up black screen. The enclosure still works, but the CARD doesn't. Since you can use whatever card you like this might not be an issue for you.

Hello all

Phew... kind of frustrating to get this Omen thing to work.  🙁  
MacBook Pro Retina Mid 2015 connected via Thunderbolt 2 with the official Thunderbolt wire 2m from Apple and their Thunderbolt 3 Adapter to the Omen Case. The card is Asus ROG 1060 6G STRIX. OS is on Sierra 10.13.3.

My Omen does not even turn on. I did try several Build guides (including the script of Benjamin Dobell) and drivers here but nothing turns on this magic machine. I can't get it awake. Now I will try to decrypt my drive and fire up BootCamp and look for Magic in Windows 10. 

Id did see a few members here having an Omen Running. Are there some more or did I just chose the wrong hardware?

Hey @markus, did you manage to make it "running" ? I got a macbook pro 2015 as well and trying to run it on windows 10 boot camp, and my external graphic card is GTx 1060. The Demon box connected visa T2 cable to T3-2 adapter -> demon box and its not even switching =(((((( Btw, is it important to install a hard drive inside or as long as there is a graphics it should start ?

I'm looking into this now to test on an old 2014 13" macbook pro in bootcamp - does anyone have it working in Windows?

Does it behave differently if you connect the Omen Accelerator to another Thunderbolt 3 device in the chain? Apple Adapter -> Thunderbolt 3 device -> Omen Accelerator. The simplest device would be something like the Sonnet Echo Express SEL. This might not work if the eGPU must be the first Thunderbolt 3 device in the chain (the Intel Thunderbolt software in Windows may complain).

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

So is it working since the last firmware updates? I can not update at the moment, i have no win with tb3 here in my circle of friends. I think about to sell the Omen if it will not work, i bought the very expensive adaptor and want to use CUDA Rendering on my iMac. Would be great.

Cheers!

Hi, I bought an HP Omen Accelerator. The fact is that I have tried it on a friend's computer and it works and it is in the latest version, but it does not work for me. Macbook Pro 2012, with TH3-> TH2 adapter.
How to make it work?
Thank you!

@torete As others have shared the OMEN Accelerator doesn’t work very well with older Thunderbolt hosts. We found the Apple Thunderbolt 3/USB-C to Thunderbolt adapter is the only one to work reliably. Also to get useful responses, you should provide as much information as possible on your setup.
