I'm still holding onto my 6900k and strix x99 board for a render node. The cpu doesn't get above 4.4 without going past 1.4v, so I may take advantage of my tuning plan warranty and send it in, maybe get a better chip. Or might be a worse chip...
Or sell it and get a 9900k, but then I wouldn't be able to add two GPUs at x16. That said, I don't think GPU rendering really saturates GPU lanes, so x8 might be fine. Decisions

Need help in understanding adaptive voltage.
I have my cpu oc'ed, and now I guess i should (?) adjust adaptive voltage.
When I change voltage to adaptive in bios, the VCCSA field disappears and there's only SA Offset left.
How should I adjust it so I'll get the value I want?
And should I overall use adaptive voltage as a must?

Adaptive voltage is neat if you want additional power-savings in idle, but it's in no way a must.
For VCCSA you will have to see where its default value ranges at, then add the offset on top of that. You could read out the default value with HWiNFO and monitor accordingly.
Usually default is ~0.9V.

Yeah you'd have to go back several pages to see voltages used mostly on auto

Conservatively, I'd think 1.2v cache and +100mV VCCU would probably safe 24/7, even under protracted heavy use. For the more adventurous 1.3v cache and as much as +250mV VCCU might be acceptable. Again though, I haven't had enough samples nor done enough testing over a long enough period of time for any of that to be taken as gospel.

When you say +100mv for Vccu what is that in real absolute terms or values? Reason I ask is I can’t tell if my board is over volting it or not..
Thanks

Wondering if someone could help me understand whats happening. I have a RVE10, I've had it since very shortly after launch, a month ago one of my USB3 ports died on the board and now just 2 days ago one of my sata ports died. I have booted with bios defaults just incase it was something I messed up in bios and it didn't fix the issue so it seems clear my board is slowly dying. My question is, is this just hardware failing? Or is there one of the voltages that could have fried it ?
Lastly if it does completely die, is it worth trying to get my hands on another x99 board to salvage the system or just moving to z390 and a 9900k ?
