Anyway, if you're running the machine all the time (like a server), or fine with the long boot, then EMR with Gigabyte is a superb solution! I'm happy you like it :)

My Q2SR build boots fairly quickly:
  • BIOS logo (Gigabyte) appears at ~30 seconds
  • Windows loading animation starts at ~1 minute
  • Desktop is ready by ~1m 40s.
Hope this helps!

Hi. I'm new to the board and I've been researching a few weeks to build a new system. This seems like just the right people to talk to. If there's somewhere else I should look, please feel free to point me in the right direction.

I have an old dual Xeon E5-2699 V3 system that I built using either QS or ES CPUs. It's been too long, I don't remember which. I am planning to something similar, but in doing research, I've discovered that there are likely a lot of compatibility issues with newer mobos and ES CPU's after reading through this VERY long thread. I've tried to do my own research, but now I'd just like to see if there are some simple answers from the experts.

I want a dual CPU machine for CPU AI inference and is at least PCIe 4.0. I was planning on using a Supermicro X12D or X13D, but I'm open to other suggestions. It looks like Gigabyte MD72 and MD73 may offer more flexibility in ES CPU offerings. I'd like advice on a dual proc board and a couple of ES CPUs with something like 48+ cores that are compatible with that board with minimal tweaking/hacking. Maybe that's a pipe dream, but I think you guys will know. I'd consider EPYC options as well though I know it isn't in the scope of this thread.

I see listing like this Gigabyte MS73-HB1 Motherboard＋2x Intel Xeon Platinum 8480 ES CPU LGA 4677 | eBay and if I can just buy an MS73 board and drop in any old ES CPU, I can do it for a fair amount cheaper, but I don't think it is that easy. Am I wrong?

it is that easy (with gigabyte c741 mobos)

not any, ask before buying.
there are single socket only models who don't work in pairs(retail not, ES not)
e.g. QYFU

there are no EPYC ES compared to Xeon 3rd/4th/5th Gen ES. only prod.units or QS(called so but not same)
you can receive a Vendor locked EPYC ( once ran on Dell/Lenovo, ever runs in Dell/Lenovo but nowhere else )

gigabyte MS03/MS33/MS73 run's a stepping D0 (E5 is final) with latest BIOS,
so NO, not same flexibility.
on EPYC platform AMD's AGESA is 100% involved and must be used by gigabyte, if AMD don't want, it don't work.

Is Gigabyte the preferred (highest compatibility) brand for running dual ES CPUs? The MS73 boards look like they are running $800-1000 USD. Know anywhere to get a better deal? I was finding the Supermicros for as low as $600.

I see pretty good deals on 8468 QYFQ and 8480 QYFS. Will those work in an MS73?

How about 8460H QY36? Would that work in a X13? Or a MS73?
Click to expand...
it is funny. there is only one unusable SPR ES at ebay and even not the cheapest, and you want buy it.
if you look at the listing: " Intel Xeon Platinum 8460H QY36 56Core 1.7GHz LGA4677 Sapphire Rapids ES Processor "
Platinum 8460H is a 40 core

There's a pair for $200. That's a good deal from what I've seen. And it's stateside and they take returns and 100%seller. I would have jumped on it if they work.


Edit: And if they had the requisite core count.

the QY36 come out of engineering servers with Debug BIOS, you never get any BIOS with support of those early samples.

has there ever been any investigation or information how it is that china has massive amounts of these motherboards, cpu's and ssd's for sale, where they come from, and how there is almost no supply in the west?

well isn't that highly suspect? without bios, maybe they replaced the bios chip with a 'special' version containing CCP HW backdoor?

i expected you talked about ES motherboards. you get them without BIOS chips. useless. with good friends you can get the BIOS(not legal)
the rule/term if you get ES parts from Intel/AMD:
if ES parts are no required anymore, they have returned or destroyed (make unusable)
