G53SW - GTX 460M Overclock

I have my 460 oc to 800/1600/1600 and have had no problems running FurMark but while playing a game like Dungeon Defenders the gpu will randomly throttles itself to 250 or lower. I then need to restart to get the gpu running correctly. Sometimes I can go a few hours without it happening, other times 30 minutes. Never had any artifacting or any graphical error just the throttling. My temps max out at 78-81. I'm guessing my oc is not stable? Any ideas if it could be the vram oc or the gpu overclock that might be causing it? For now its only happened while playing Dungeon Defenders and not in other games like Crysis 2 or Deus EX HR, but I'm thinking that's just because I haven't really played those games much more then 30min at a time on this laptop.

On another note, what kind of temp differences are people seeing while overvolting the 460?

 

Hi,
Probably you need a bit of overvolt to stay stable. I've got an increase about 2-3c going from stock to 1.0v.

Or you could try to lower memory clock speed.
Try as an example 810/1500. If you're fine, you may try 1550 but not 1600 since we know it's not stable on your end.

If you're not stable again, try 800/1500 and see how it does.
Probably with 1.0v vbios you'll be able to reach even 830-840.

 

Thanks! You wouldn't by any chance have a link to the best vbios for that would you? I have skimmed through the gtx 460m overvolting thread but saw that they have a few different vbios?

 

i have a 460m in a g73 OC'ed to 800/1600/1480

so it could be your ram that is too high

You see different vbios because each bios is provided by the user itself, and Saltius takes his time to mod it
Althought theres an how to for DIY. Althought another laptop vbios would work, its highly adviced to use your own one, and youll need to use nvflash to dump it correctly.

 

Did you guys repaste or something?

When I try 800-1600-1400 it idles at around 50-51 degrees and furmark was reaching 88 degrees. I stopped furmark on the fear that it was going higher

it was all running stable, no artifacts, but it was getting nowhere near your guys temps.

 

Furmark is no more needed for gpu stability. It just put the gpu to excessive stress and heat.
Thats because fermi architecture has a power limiter built in the vbios which blocks the card from overheating and burning.

Mind you: under furmark at 850/1670/1600 I was reaching 93c, which is higher than your 88c by a good margin.
The temps were taking about is under gaming mainly, having 84c as the higher temp reported when I had the g53sw.

If under furmark u reach 88c I'll guess that in gaming you'll be fine at 80-81c.

 

88c wasnt the highest it got, I stopped it during the process cause I didnt want it to get higher.

so far in gaming, the highest it goes (crysis 2 / dirt 3 1080p high-ultra settings) gets around 84-85

the overclock didnt do anything to the temps from the original

So as long as I dont flash the bios or anything, the original bios will keep my graphics card from overheating if I overclock during long hours?

 

I setup my G53sw gtx460m up to 815 1250 1650 and runing 3d mark2011 and betterfield3 in ultal 1080P model is stable, no black screen or error occurs during game playing. And the highest temp is 80c.

 

^ whats your fps on BF3 @ 1080p and ultra. Cant be over 30 right o.0?

 

Impossible,thats for sure. Maybe a mix of medium with textures on ultra makes sense, but it struggles anyway.

 

yeah thats what I thought too
