ASRock Rack EPYCD8 Series Make For Great Value AMD EPYC Motherboards With Rome Support

[Michael]

On geizhals.de
ASUS KPNA-U16 353€
Supermicro H11SSL-i 370€

But I think with both mobos you have to ensure to get the second revision with 32 MB BIOS/UEFI flash.

Unfortunately the ASUS board doesn't support Rome. The Supermicro does support Rome only as a "Rev 2" model, similar to ASRock Rack. Unfortunately the ones at $399 USD at least from US retailers appears to be Rev 1 still.

(I had been searching for several weeks to figure out the best value Rome motherboard, so far it still is the ASRock Rack EPYCD8 AFAIK.)

I am waiting for a 2p board to support Rome before moving on from my 4x6378 opteron system. These seem to be taking a long time to be available from most manufacturers.

In terms of real-world use though, are there many ROCm users with EPYC + Vega consumer cards? Just as I assumed from the original comment, the focus was on loading it up with multiple cards for ROCm tests. So just wasn't sure if there was a lot of EPYC + consumer card usage as well as how well ROCm works these days when multiple cards are not the same model?

It does if it is Rev. 2. The ASUS support page however seems not updated yet. And even if you have the first revision with 16 MB BIOS flash, a computerbase.de user contacted ASUS support and they offered that he could send in the (socketed) BIOS flash chip and they would flash a version which supports Rome (but no longer Naples).

The Supermicro mobos that Newegg sold as bundle with Epyc 7002 CPUs definitely were Rev. 2. The ones sold individually however, at least until recently, were still Rev. 1 indeed. So if you are in the US the best value would have been the Newegg bundle.

[Update:]
I would like to inform you that I was recently able to establish a validated TLS connection by adding an s in the URL: https:// instead of http://
This was previously impossible.

BE CAREFUL!!!

ASRock does not offer TLS encrypted downloads when you have to update your UEFI/BIOS!!!

You have to live with the risk that you become victim of a MITM-attack slipping you a compromised UEFI/BIOS stealing your IP!

I can‘t recommend any of these until this fundamental fail will get fixed. TLS is really just the completely essential minimum security for file transfer.

Fair point - I wasn't thinking about it as multi-GPU focus, will go back and check.

I think ROCM usage is mostly either (consumer CPU + consumer GPU) or (server CPU + Instinct GPU), but the ROCm behaviour should be similar other than premium features like XGMI links, large BAR support, server-type cooling and full FP64 speed. I believe single GPU perf should be similar other than FP64.

The market sweet spot for Epyc is to reduce socket use in the datacenters typically, so 1P is going to be pretty popular, but the 2P layouts do exist. In fact HPE markets their Epyc line exactly that way "2P performance in a 1P format"

Dell only has (2) 2P form factors and both are rack mount formats.

You can replace that entire 4 socket system with a single EPYC and likely save on your power bill while having twice the threads. Unless I suppose you need the memory support that dual CPU sockets gets you.

Although I think a dual socket EPYC with 3 TB of RAM is going to cost in the hundred-thousand dollar range in which case why would you build your own.

In case this is still relevant: I just came across a report on STH forums from someone who confirmed with superbiiz.com that they sell the Supermicro H11SSL-NC Rev. 2. That post is dated 8th October.

I recently picked up a new Supermicro chassis in preparation for a future upgrade to Epyc. I purchased from an official Supermicro reseller and inquired as to when ATX form-factor H12 boards would hit the market. It sounds like Supermicro is targeting ~December to drop the new boards which will include PCIEv4.
