You need to keep an eye on the VRM temps.

They basically feed the GPU and memory with voltage, keeping it solid and stable. They can get very hot and if too hot will cause instability (and reduce the life of the components).

@ gurusan, thanks! rep+

@ munaim1, couldn't find anything after a quick search, but you can do this yourself! Download this then get your bios and you can add volt and so on! I did it to mine
Cheers!

its worth it! In crysis it helped a lot, you can go from 25fps to 30fps in the hardest places! So I think its worth it! Also gives me 10fps extra in GTA IV some places, so go for it

I would either get watercooling, or buy a 5870!

Try your fan at 40-50%. For me 40% the noise is minimal and the temps never go above 65c under load.

It's not worth it to OC any 4870 card right now, you won't really get any "real" performance boosts. Maybe a few fps but do you really need that? You get a hotter card and create so much noise from the 60% fan speed.

If you want to OC that card, you'd better go out and get yourself a good aftermarket cooler. IMO OC'ing a 4870 HD card will only give you higher benching scores, no real profitable gains in gaming.

I notice a difference going from stock speeds to 875/1150 in CoD4.

I'm under water though so really don't worry about temps or fan speeds. 25C idle and 30-32C load
