Are you using any monitoring or other programs that are keeping your GPU in the 3D gaming performance state? If you're not sure, then have all your programs closed, and just use GPUz to monitor your clocks. I don't imagine that the vBIOS has been designed to NOT clock down, so I'm figuring you've got something open that is preventing it down clocking. If that doesn't work, then i'd uninstall the graphics driver, then use a program called Display Driver Uninstaller (Display Driver Uninstaller Download version 12.7.1.0) to remove any traces of the graphics driver, then reinstall 337.50 drivers (using your modified inf like you normally do).

Good that you managed to flash & run the new vBIOS well. How do your temps look? (I'm just curious, it's nothing to do with your card not downclocking issue).

What program you use for monitoring real current frequency and voltage? Just use Nvidia Inspector and you can see after benchmark that frequency and voltage will reduce.

Thanx guys. I was only running MSI AB to oc and monitor. I also have HWINFO for fan control.

Turns out that I forgot to reinstall the drivers (too excited about getting the modded bios and getting down to some oc'ing )

After cleaning out the old drivers (thanx for that link Robbo) and reinstalling, everything looks like it's working like it should.

So far I'm up to 987mhz core and 2124mhz mem. Temps only went up 2c (70c max) after a 20 min run of Unigen, so pretty happy about that. Thanx to Klem also for suggesting Nvidia Inspector. I like it a lot. Seems lighter than AB.

I didn't realize how much more challenging OC'ing on a laptop would be. On my desktop everything is water cooled, including the motherboard chipset, so I just crank-away! LOL Very much different that this air-cooled, closed-quarters environment.

EDIT: I'm assuming that all of those MSI 680M vBIOS files are for the 4GB version, as there is no mention of a 2GB MSI 680M, and your existing vBIOS (80.04.33.00.24) on your 4GB card is the same version number as those listed, so I reckon they're for the 4GB version of the card. If you flash it, let us know how it goes.

OK, so I flashed the MSI 1.025v bios like you suggested. Everything went great. OC'ed it to 936mhz, ran 3DMark 11 and everything looked good. But upon finishing the test, the card will not throttle back to 2d clocks and voltages. It just stays at 771mhz, 1.025v. Is this a known quirk? Or am I not setting something correctly?

I'm running the 337.50 beta drivers.

Thanx

GPUz says Dell (1028) because you have a Dell or Alienware laptop, and GPUz will always report it as such regardless of whether it's an MSI/Clevo/or Dell card. (It reads the 'slot info' - [made up term!], not the GPU itself). You definitely need to flash a 4GB version of the 680M (not a 2GB version). I would flash one of the 4 MSI vBIOS's if your card is working fine at the moment in your laptop - that way you're just using a modified version of the vBIOS that you currently have. You can choose stock voltage, 1V, 1.025V, or 1.05V versions. Depending on your temperatures, choose accordingly.

EDIT: I'm assuming that all of those MSI 680M vBIOS files are for the 4GB version, as there is no mention of a 2GB MSI 680M, and your existing vBIOS (80.04.33.00.24) on your 4GB card is the same version number as those listed, so I reckon they're for the 4GB version of the card. If you flash it, let us know how it goes.

Yep, you're correct. I exported the bios with KBT and it's reporting MSI (1462). Feel a little better about getting the correct modded bios now.

Hey all. I've modded many bios before with NiBitor and NVFlash, but right now it seems that KBT is the only tool that will work on the GTX680m. Has anyone here used it? If so, have you had success with it? Is it relatively intuitive? I'd like to try my hand and modding the bios on my card.

Thanx

Hello all!

Been tinkering with PCs since 1999. Done numerous desktop hard mods (mb volt mods, gpu resistor and vr mods, the dreaded "pencil" mod LOL) and built my own custom water cooling systems. BUT...I've never owned a lappy till about 2 weeks ago when my buddy's M17X R3 blew the gpu and he sold it to me for peanuts. Just got the MSI GTX 680m and Googled my way here trying to get maself edumacated ;-) before trying anything crazy.

Looking forward to leaching info off the knowlegable folks here to OC this lappy into a beast. :-)

Cool!

I've oc'ed it to the possible max in AB right now (+135 core) and after letting Unigen run for about 30 mins straight, the max temp held between 63c-67c. Idles at 30c-33c (sometimes dipping into the high 20c's). In the game I'm playing now, Dead Space 3 (yeah, yeah, I know), temps don't even hit 50c; usually haning between 40c-45c.

I did do the copper shim mod with ICD7 (again, yeah, I know) and used some Fujipoly X; so the decent temps may be due to that.

Thanx for the quick reply.

Hi all. Quick question: I purchased a GTX 680m on Ebay that said it was the 2gb version. When I got it, it turns out to be the 4gb version, BONUS. ;-)

However, in GPUZ, the vendor says "Dell (1028)", BUT the bios version says it's "80.04.33.00.24", which according to the mod bios list on the first page of this thread is an MSI bios????

So if I was to try one of those modded bios, which one should I choose? And the original post mentions the GTX 680m 2gb bios, but not the 4gb. Would a the bios be the same for both version?

Thanx
