I've had two of these for a couple months. Also skeptical about the seller's claims about them working if they're just dropped into one of those dell servers - he told me the same thing. I'm pretty sure they required some unreleased firmware, like you mentioned. If we could get hold of that firmware image, perhaps we could figure it out - even better if we had a complete running system. I have the same thing as you with the RIVE - 39 multiplier, 42 turbo boost single core. I can get it pulling 275W TDP and it start hitting 92C even with good water cooling - suspect my CPU water block can't dissipate that much heat. IDK. Windows reports 46x all cores. I'll try booting into Linux soon and see what I get there. at 3.6Ghz @ 1v vcore, I get normal Ivy Bridge temps and performance. Running it right now at 'sane' values until we figure out how to get it working to its full potential. The firmware is likely setting some MSRs to enable the full clock speed? I don't fully know what it would be setting or what's holding it back. I'm reaching out to some firmware engineers I know since I only know about older AMD processors (K8 / Fam10h). *Edit* also the seller was incorrect. The processor has a stepping of M1 which is Ivy Bridge-EP-10 (if that's what he meant by 'STEP'). It's a 10 core die, 25MB L3 chip with 4 cores disabled.
