    Confused, Geforce 460m not clocked right?

    Howdy everyone. I was investigating why Skyrim and SWTOR are running just a bit slower than my buddies, and discovered my Geforce 460m isn't clocking correctly.

    From what I've seen posted, the speed should be 625MHz core by default with a VDDC of 1.0V. The max I am seeing is a 570MHz core with a VDDC of 0.9V. In the discussions with other people having this problem I've seen no solution. Playing with drivers, power managment and so on had no effect.

    Am I missing something here? Any help is appreciated!

    Hi,

    460m is downclocked by Dell. You can easily change the stock settings (eg nvidia inspector).

    Alright, so I found mention of a new dell VBIOS and applied it to the video card. Now everything looks clocked correctly!

    Unfortunately, the GPU Temp hit 91C during SWTOR, and it began throttling a bit. I've cleaned everything out but it still seems to run about 15C hotter. This may just be normal, and I'll have to attempt a reseat/repaste of the GPU. Idle at min clocks (50/67/101) I get about 46C.

    Anyone else using a Geforce 460m at 675MHz in an M15X with the stock 260m cooler? What are your temps idle and under load?

    Oh, and I noticed my fans aren't running at max speed either when the throttling occurs. Anyone know how I might force them to rev up?

    Thanks!

    Well, I've got a 560m with the stock 260 cooler. My idle temps are between 37-40c. Highest I've recorded during gaming is 72c

    I'd say that your temperatures are higher than they should. But I don't know if the 460m just runs hotter.

    Can you post where you found the vbios? I am having the same issues. My default clock is 575 where it should be 625. Thanks.
