    Ok so I'm flashed my eVga 6800 nu to 1.5 volts.... If I could've done 300 volts I would've but 1.5 is all I could do :)

    Anyways, right off the bat my 2d temperatures were WAY up... 64c IDLE!!!

    Obviously I didn't run my 2d overclocked but just for the hell of it I ran my 2d at 350 / 750.... I noticed 5C drop in temperature.... By the time I got to 410/850 the drop in temperature was 20 !!! 20 degrees Celsius ladies and gentleman.... On 1.5 volts...

    Needless to say that when I game the temp doesn't go much over 68C....

    So volt away, but increase your 2d and 3d clocks by a lot if you do....

    Running stable at 410/415 is pretty cool **** eh? Especially when you have all vertex processors and pipelines enabled....

    i have a softmodded 6800nu and run at 410/850 too but at 1.4 volts with no problems.

    Meltdown, ;)

    These processors were not made to run at 1.5v that is why even the 6800U is not at 1.5v. It will limit the life of your card by how much is anyone's guess. I know of a 5900NU that crapped out in one year due to being at 1.5v, of course I know of a few that did not.

    Thats a mad voltage to be at 24/7. My card ran at 440/950 at stock. After i enabled all the pipes i can still run at 425/920 without a volt mod, although i do have 2.2ns memory, which helps :) My card runs at 41c idle and 46c load...........happy

    Danger! I know a guy which uses 1.5vGPU in combo with an AC....he gets 500/1330 on his golden sample GT......only for tmeporary use..

    Your are killing the card....max you should do is 1.4vGPU, but still your temps are waaay too high, and that's only 2d.....

    How can I kill the card?

    It's really spooky. If it's at 325/700 I can see that the temperature is 68 idle...

    I up the speeds to 410/700 and it drops to 40 C magically.... 40C is a very safe temperature from what I'm told....

    Besides, in one year this card will be crap.... Why should I save it for the future? With every day and second it loses value... I want that card to sweat every frame it can give me :)

    1.5 is plenty safe .... There has to be a very logical explanation for needing to run higher clocks at higher voltages in order to keep the temperature down.... However at 40C idle I have nothing to worry about. And if it dies... at least I know I made that bastard card work for every fps it could give me...

    Trust me, if I could go 220 v on the core I would.
