GTX460 recommended V's @ 850/2000?

post #1 of 16
Thread Starter 
As the title reads. As of right now I'm running 850/1700/2000 and was wondering whether my .975v were enough for that overclock. I'd also like to reach 900/1800/2100 eventually, what voltage should I use for that?

Cooling is stock.

I stayed at stock on mine at that clock, but I have a normal card, not a SE.

Same here. I kept it at stock voltages for 850 core. I recently upped it to 1.050V for 880 core.

You can tell if your voltage is enough by either playing games and looking for artifacts or running something like 3DMark11, Unigine Heaven, or Crysis benchmark tool and also looking for artifacts in those programs. I would guess that you are actually not stable at 850 at just .975v.

Once you determine what voltage it takes to make 850 stable then you will have a better idea of what it will take to make 900MHz stable but I would guess that you will require near max voltage which is 1.087 I believe.

I'm actually completely stable at 850... I ran Furmark @ .950v and 885/2000 yesterday night and I still had no artifacts or crashing. The only thing that annoys me is the GPU load that goes up and down in games, but that happened @ stock clocks, too. No big deal.

I would also use something that better simulates actual games in addition to just Furmark. The 3 programs I listed above are all pretty good and are all available for free online. There are also some cool demos here, I don't know if I would call all of these stability test but they should be somewhat useful. Just use something in addition to Furmark.

You have the exact same clocks as me and I run my cards at default voltages. Works flawlessly.
Note: only stock cooling aswell.

Whoa, you guy have some bad overclocking cards. One of mine runs at .975V and the other one can run at 1V.
