EPYCD8-2T Serious issues

Hi mates. I think that my EPYCD8-2T failed on me (at the worst moment, of course).

My plight started 2 days ago, when I added the fourth GPU. The board did not boot properly (no screen output), and after the usual 30/40 secs, the power draw skyrocketed at almost 300W. No ssh server running, so the OS was not booted. BMC unreachable. All the fans at flank speed.
I couldn't see the Dr.Debug display, since they intelligently placed it under the fourth GPU, so I detached that GPU. No success, but at least now I could see the display. Pretty useless, since it displayed the vastest amount of codes, and ended up with a countdown from 90 to 01 (see the video, it starts at 0:19).
I detached all the GPUs save one, the all of them. No success. Lower power consumption but still high (>200W) after 30/45s from boot.

I noticed another strange thing, which makes me suspect that the board is indeed broken. While powered off, it always absorbed 7-8W, probably because of the BMC (a normal pc draws 1-2W on the average). Now it draws 20-22W, which is almost impossible even considering the BMC. Furthermore, the heatsink over the 10Gb NICs is so hot that you can hold your finger on it for just an instant. It was NOT so before.

Of course I cleared the cmos and even replaced the cmos battery. No success.

Any clue?? :-/

I understand you had a 12 V pci-e cable connected as a 12V Power Connector graphics ?

Thanks for your reply. Yes, if you mean the 6-pin PCI-express connector, I connected it even before purchasing the fourth graphics card, specifically not to forget it..

1. Have you figured out this yet? Its May, and your post dates back from Feb.... I may be late...
2. Have you pulled everything (except of course what's required to boot a system) and proceeded by elimination?
3. Have you contacted Asrock? When I had a freak occurrence with my Freenas server (supermicro hardware), I contacted them and they figured out pretty quick what was going on. $48USD shipping back & forth, 10 days, and the mainboard was back fully Q&A checked. Its been rock solid for 7 years now.

Sounds like you definitely have an electrical issue somewhere ..

Point 2: Yes.

The board stopped working altogether during the subsequent weeks. Returned to the vendor. I took an Intel board as replacement since I was in a hurry for having a working system. Also, I reluctantly returned the epyc 7282 to amazon.

It's a shame. The epyc had stellar performance with a low power draw. My experience with Asrock has been dismal, but maybe I have been just unlucky.

Thats too bad, at least if you got it sorted out....

I myself try to avoid manufacturers who's bread & butter are gaming components. Gamers and us are two different crowds with different needs... I only buy Supermicro, quality wise, I've had board running for 12 years without a huiccup and when I had problems, they charged nothing for a series of tests on a H8DCL-iF (I only had to pay shipping to them from Canada).

My problem with supermicro was that I needed a board capable of supporting four GPUs, and the only epyc rome board that could do that was the Asrock one. Indeed, I'd want to give epyc another try, and Asrock has even released the beefed up version of that board (ROMED8), but I just don't want to buy another Asrock product.

Since there are so few boards with four mechanical 16X slots no matter the epyc monstrous number of pcie lanes, it seems that AMD wants you to buy a threadripper for workstation use. For me, it is a non-option. I need RDIMM support and low power consumption, and the TR provides neither.
