Mhm but isn't that rule for on water? I only have 1 card on water currently.
With how the air one is performing to how the water one used to perform on air, I'd say the cards are close to equal, and that 800/linked/1200 should pass fine @ 1200mV. (Which was the JohnK800 rule IIRC)
I had the PSU give out on me last night I believe. I was at about 760/linked/1250 with 1188mV, and in the part of New Calico where the rockets are going through the asteroid field the whole system just shut off instantly. Kinda cool but scary at the same time. I get the feeling when they're both on water doing 800+ that I'll need to use my Silencer Pro Gold 800W for the second card.
I'm still not sure though why others were getting 40-41k at these clocks though.. That confuses the hell out of me.
