I've been running mine for a few weeks now on the ASUS bios (790/925 i think), everything is fine except when i load the crysis demo it starts making funny noises!

Even during the intro videos, it makes this high-pitched squealing noise, stops when the screen changes (in the intro screens) then starts again. It is constantly going whilst navigating the in-game menu until it crashes (yes the menu crashes it).

Now i'm not really fussed cos i don't play crysis (i only have the demo), but i'm a little perplexed none-the-less.

I'm running Cat 8.7 on XP Home SP3.
I get the exact same. Well mine happens in Furmark, and other 3D apps. Some apps do it some don't. Seems to be the way in which the app stresses the card. quite annoying.
