Even at -30c i had trouble with 1420 at only 1.21v,out of 4 i had 1 went 1385 for just a bench or two but 1340 was ok for games.

I played some vantage last week testing that tweek was ok

DCII's @1.40ish H70 cooled / 3930k H100 cooled close window added 40c air into the mix
Was good for 1437 in sli max temps 59c


single card i pushed to 1.45v good for 1475



Have a card and RIVE mounted for dice but i cant get any this weekend..
I hope i can hit 50k single next time
