Yo

Whats the word on the street about the max safe voltage for these cards?

Afterburner lets them go up to 1162mv

Cheers

as long as you can keep everything cool at that Voltage (VRMs, Core, ETC....)

that voltage is fine

but in saying that....

more voltage doesn't always = bigger OC

i mean i can get 860Mhz core on both of my 480s @1.1v...

and 900 core on one of them (wish they both did this)

but i can only get 820 Mhz core on 1.2v!!!!

heat isn't a issue since they are still only running at 68 Deg C at 1.2v 820 Mhz core....

they just don't like the extra volts....

Been running 1006 @ 1.13v on both my 450 GTS (Sonic Platinums) in SLi without a hitch... really thinking I am going to try for a little more... keep in mind though that (nearly all if not all) these cards stock coolers do not make any contact to the vrms, that said, it may be a good idea to come up with an aftermarket cooling solution.

Part of the problem I ran into was that the HS sits ontop of the board, and under load for any amount of time would just get too darn stuffy and overtemp the vr's causing all sorts of stability issues upto and including crashes.

In SLi I could not pull it off due to air restriction on the stock coolers, but now im on water, and with core temps out of the equation, these little cards do amazing things @ the $. thinking.gif
