one Optane....Interesting, but I don't get it? Where to look? What is the issue?

no, we have PMEM 100, PMEM 200 and PMEM 300OK. Optane was ddr4 right?
sorry i don't know.I right understood that 8259CL have "old" memory controller of Skylake-SP family or may be another not know me problem?
Thanks. I understand this. I have six modules and think now how found support it CPU for good price))sorry i don't know.
'C' confidential SKU for select customers. you get no info about those.
Skylake ES. you have cascade lake now. this gen was not alive the time your BIOS was build.because my understanding is only the 2.0b supports ES CPUs
Platinum ES 8260-QQ89 is stepping A0 50655I notice in Supermicro's page for the -F - It says BIOS 3.0a/3.2 is required for 2nd gen Scalable.
update to 3.8 first. imho the QQ89 should work with BIOS 4.5 but not sure.Do you know if I need a special ES BIOS mod or specific version? If it helps, this is the eBay listing: Intel Xeon Platinum 8260 ES QQ89 24C 2.4GHz 3.1/3.9GHz 35.75MB 165W LGA3647 DDR4 | eBay - 4.5 is the latest available on Supermicro's site.
i am not sure but you may have to stay on BIOS 3.x after upgrading to it for security reasons.If I get stuck with neither my new or old CPU working, what would be the best way to recover? Is there a way I can backup my current BIOS before I do anything?
QQ89 is working with at least BIOS 3.0c - stepping A0 is used by Production units and QS as well.I want to have a bit of a plan before I take an action that might require a lot of time to undo. I have 2 of these servers to upgrade, both identical.
that is the most usual case fro ebay seller from china.Makes me think Q03J and Q03Z were coming from a single source even though there were many sellers.
OC on W790 is limited to memory, QYK8 runs already at max. 4Ghz shortly before fused per core current limit.Well I purchased a QYK8 from ebay (at least that's what the picture shows) and I already have 8x32gb DDR5 4800 from my abandoned Epyc build. Now I am curious what people think I should do motherboard wise. I was thinking either the Gigabyte MS03-CE0 or the Asus W790E-Sage?
Awesome, I appreciate the info on the PCIe lanes, that is a bigger reason to go with the Gigabyte anyway. Sadly I've corrupted a few OS installs messing with BCLK overclocking in the past hah. I'm going to pick the Gigabyte. Thanks again for all of your help!OC on W790 is limited to memory, QYK8 runs already at max. 4Ghz shortly before fused per core current limit.
And BCLK OC affects PCIe USB/Sata too and gives trouble with new PCIe GPU Cards.
On Gigabyte C741 you can use latest BIOS and you do have all PCIe lanes/outputs available.
if i had know Gigabyte is an option for you i would have hint to a look to the Emerald Rapids SP stepping A0 ES like Q2SR,Q2SP,Q30G,Q30H,Q2T7.Awesome, I appreciate the info on the PCIe lanes, that is a bigger reason to go with the Gigabyte anyway.

Ah bummer, I shouldn't have made it seem like I had the W790. But having said that, I don't know if I would know how to order from goofish/taobao hah. Are there any advantages of Emerald Rapids over Sapphire?if i had know Gigabyte is an option for you i would have hint to a look to the Emerald Rapids SP stepping A0 ES like Q2SR,Q2SP,Q30G,Q30H,Q2T7.
all have 4Ghz turbo(half of the core count) but you need a BIOS tweak because without they take over 6 minutes to POST.
e.g. Q2SR 64C 350W crrently only goofish/taobao for ¥2000 (+ ship/tax etc)
LOL. you can run (jedec)5600 memory with Q2SR and Q30H. they have only 2 chiplets in XCC configuration, and much much more L3 cache.Are there any advantages of Emerald Rapids over Sapphire?
