That’s which bios position? Normal, OC, LN2? Assume it has 3 like the 3090

Anyone care to push it to LN2 bios and send like 1.3 nvvdd on stock cooler? Should be perfectly safe

That's the ln2 bios. Only one I've tried so far.

I haven't used the classified tool yet but 1.3v is a little high for me. I only did 1.3 once and experimented between 1.15 and 1.2v a little bit and it degraded my 2080 Ti KPE. It would run stock but literally any core OC was unstable on one card. It would be stable enough for a 3dmark run so it wasn't a huge deal but it went from me being able to run pretty much any game at +100 to pretty much anything past +30 crashed within half an hour. The other KPE that I never pushed past 1.15v still holds up at +100 in games which iirc was like 2130 mhz.

Interesting. Not sure how anyone is hitting the PL at stock bios then. Even Luumi seems to have seen negligible improvements with even a small amount of core voltage (1.18 nvvdd PLL 5)

I wonder if what we are seeing with the 3090 Ti is a vrm capable of powering the 40 series and so it barely breaks a sweat here. Surely twin 12VHPWR are overkill. May explain him saying the xoc bios isn’t needed. I’ll send it this week so if you aren’t comfortable pushing more voltage just wait and let me take one for the team lol

I've still got headroom on the ln2 bios and it isn't doing anything funky where is hitting pl on some rail but not the board limit. That said, my 3090 KPE would hit about 480w and putting it to 1.15v would send it above 520w. But maybe you're right and the VRM can keep it it efficient enough where it doesn't need much more voltage.

i'll tinker with it this week. you've seen the Luumi vid i assume? stock he was able to get it to 15800ish PR just w px1 sliders no classified. with classified it was slightly worse. did it need even more nvvdd? hard to know from his video but it is not hard to know from my own testing :)

Yeah. That's the way my 3090 KPE was too. I could never get a higher score with any more nvvdd. I think fbvdd helped with memory but that was it.

Wasn't able to get more than ~105 offset on the GPU using PX1 so I pushed through 1.25V on nvvdd on the classy tool just to see if it helped.  Didn't crash immediately, but the heat quickly got out of control and was dropping clocks.  So tanked the score on PR.  Was power limited on that run win the LN2 bios.  If I could control the heat better may be some benefit.  But also likely a better balance for voltage.

I was able to get +120 on the core but I think my memory above like +600 was making my score go down which isn't great. I was getting really bad artifacts at like +750.

makes sense. more cores = more heat. prob be cheaper to get a portable AC unit from target and send them SLI before i refill LN2 later this month

Luumi was running like +1515 mem before it crashed so he must have one of those good bin special deliveries from Vince

Memory I think I could push +1000, but anything higher caused a hard crash of the system. Still have a lot more playing around to do. I'm trying to convince myself that since there's no waterblock, I can just spend the money on a floor AC unit for it.
