Reading through this thread, I came under the impression that W790 Sage BIOS beyond the first loses features (RAM overclocking, unless I misunderstood) and compatibility with ES CPUs. If that isn't true, then I have no need to downgrade the BIOS.
RAM OC was available for SPR-SP ES by mistake.
keep in mind that there is no intented compatibility with SPR-SP, they run because there are SPR-WS stepping D0 ES.
if you downgrade to have RAM OC you loose security, if you agree to this have fun.
processors sometimes break, even more so when they're overclocked. That's usually not a problem; you have a warranty. ES aren't manufactured with the same care as retail processors, so expect a much higher failure rate. I'll never understand why people aren't happy to have a cheap CPU but instead do everything they can to destroy it.
My intent wasn't to overclock the CPU, but to potentially have the RAM go at its listed speed (mine are Hynix hmcg78agbra188n, 5600mbps ) as opposed to the base speed. Also, I'm completely unaware of what security flaws the older BIOS would have compared to the more recent BIOS. At the very least, I wasn't intending to use the system for anything that I would understand put it at risk nor was I going to use it for downloading files on less-than-reputable sites.
That dude is just ranting, ignore him. Stay on the lowest bios that works for you. Most likely you are going to use it for your non-enterprise use cases and you would be just fine. If you are using an engineering sample processor staying on a lower bios just make sense. Given that you are using an Intel confidential CPU to begin with, those security fixes in the upper bios aren't really your major concern right now. So yeah just ignore that other dude and stay on the initial bios that was released.
to get that 5600 you have to OC the memory controller. Sapphire Rapids = only 4800
why do they provide new BIOS ? microcode (not D0 ES) fixed bugs, found vulnerabilites in Intel ME, UEFI (logofail)
He’s not ranting. Memory controller is part of the CPU . By forcing it work outside of the specified parameters you are overclocking it. I do run 9480 D0 with memory overclock but I have a tray of 4 spare processors in case I fry one or two. When I will only have two left I will stop playing this game and will run memory at 4800 as intended. Frying memory controller on SPR-SP D0 is not unheard of.

that's what I was commenting on. And you need to always know what you're doing when over clocking. With more power comes more responsibility.I'd rather have more power and more responsibility, than not. But to each their own!
you forgot OC memory needs more TDP stolen from the cores, that's no problem only with 'X' SKUs.
you get responsibility only by a windows tweak (idle promote/demote threshold)
Nope I forgot nothing, and again, I'd rather have more power and more responsibility -- both.
No, I may have seen it but not posted in it. Link?
EDIT: My phone is clearly listing and recommended me the reddit link to local llama “texasdude11” who I have seen on YouTube

Not a fan of asrock? I’m not worried about out having it rack mounted. Purely after advice as it’s half the price and wanting to know what I’m getting for my money. I’ve been using the search and there any many gigabyte/asus builds but no real comparison or what one is substantially more expensive.
Thanks
Totally different use cases. ASUS board is expensive but can run pretty cheap ES variants of Sapphire Rapids like the famous QYFS 8480 D0. This processor can be purchased for like $100-$200 now. ASRock Rack on the other hand is cheaper but it will not work with these cheap processors so you will have to buy much more expensive QS or retail variants. QS 8480 sometimes can be bought for like $900 and it will give about the same performance as QYFS on ASUS. So choose your poison
correct. i have one again, because it was cheap.BMC destroys BIOS chip, update BMC FW first or you need new chip,
BIOS support is rare, you have to beg and plead for non Beta BIOS with 5th gen support, they have but not on they're page.
many other ASRock Rack motherboard did'nt get any BIOS updates after years, even not solved the known AMI vulnerabilities.
Good to hear your opinion, I didn't know that about their BIOS support! Shame as they on paper at least have nice features etc.
