Overclocking a laptop is stupid, but I did it anyway. I'm not sharing how I did it or the clocks I achieved as I don't want anybody that doesn't know what they're doing to do put in my numbers without working up to them and blowing up their system.
I can't recall the clocks on this anyway, but during my OC I accidentally did a run in the middle of the process on a single card and scored in the 7300's for a single gs.
I stopped pushing the dual cards once I reached 11,026 as it was my goal to reach 11k in 3dMark05. I didn't have any issues overclocking the SLI setup.Read all about it here.
I can say however that I achieved much higher mem speeds than the guys overclocing the Dell with the 7900gs, but I didn't overvolt the gpu so I wasn't able to push the main clock as high as they claim.
I've been playing Oblivion and F.E.A.R. on stock settings at 1920 x 1200 and it plays well, so there's really no reason to overclock this platform.
