To be honest i never experienced this "cold lock" and i dont know if it exist in the first place. I guess some cards might have it but i boot when the card is @-28c at first so there is no problem there. I have Gainward GS and so far no "cold lock" for me. Dont know for sure about other brands. Shamino also using some brand that dont have this issue. Actualy i have never seen the card that had "cold lock" so this might be a mith :cool:Quote:
But do we know this actually works for the cold lock issue?
By the way i'm using PNY 6800GT versioin2 Vmoded bios on my card so you might be in luck with this "cold lock" issue Uclajd
Very sweet, thanks for the info. I think you are right, the "cold lock" is probably just throttling in action.Quote:

Amazing, even with a ghetto'd raddy and fan (needs a shroud desperately), my load (UT 2004) temps dropped from 80C+ to ~46C.
My stock air max was about 407 stable, although with the Vantec cooling card it did auto detect to 427 once. So I flashed to 1.5, and played UT at 450 for over an hour (didn't change it to 450 in BIOS yet, as I need to do more stability testing, but it didn't throttle once under UT 2004 load).
One thing I realized, is that power is a huge issue. I had this thing sharing a 12v lead, big mistake. :eek: They need their own dedicated lead, chain everything else to the other line (I know that some 6800 manufacturers recommend this). I think the 1.5v flash really helps, since I doubt the card is actually getting that much juice. And now with my temps way under 50c, the card loves it.
And for those "experts" who say nobody needs a 500W+ PSU, they are full of it! :bs:
I am seriously thinking getting a SFF PSU just to run my drives. :mad:
Next project: Peltier. :D
