nVIDIA mobile Kepler 6xx MASTER overclocking guide. Workaround for max clocks/OC stability.

Did you use option of clean install driver?

 

Mobius 1, great guide! Here's the result from my Y500: http://forum.notebookreview.com/ideapad-essential/700135-y500-gt650m-overclock.html#post8987802

 

Glad that you're able to do it

What other things that you have to change (system power profile etc?) to break the limit?

 

I did but I might try again...

 

What GPU do you have?

 

Huh, I thought I had it in my signature x). GT650M with GDDR5.

Update: Huh, so I manually downloaded and flashed the latest BIOS:
http://www.dell.com/support/drivers...-17r-se-7720?driverId=GH4PH&fileId=2970873797
And so far it seems to be boosting again. I'll see if there are any major drops, otherwise I probably won't push it because I don't like the noise and I have the i5 version with a 90W adapter (which I love because it's so light, just in this case it "might" get unstable).

 

I've been unable to clock the GPU core of my GT650M with 2GB GDDR5 higher than 1000Mhz. I used clean install with my Nvidia drivers. Clocking higher than 1000Mhz will cause BSOD...
Anybody idea? Is it the Dell, or the bios of the 650?

 

(copypasta'd so maybe someone in this thread can help me)

Okay, maybe it is just me, but every time I setup a value for nvidia inspector I it gets 'locked' into that value, and doesn't change unless I use a different value for an underclocked state. This is all fine, however, if I restart/turn off/ close the laptop it then goes to 135/405 and stays there. Not even using my nvidia inspector .bat works to restore the overclocked state.

Here is what I'm using for my overclocked .bat

And my underclocked .bat

here is a screen of my y500 after the clock speeds/memory speed has been 'locked' (also, using latest driver) Not to mention, trying to put the clocks on 1110/2900 and applying them from nvidia inspector simply puts the slider back down to 405/800.

I can't get this to work on my MSI GE60 (GTX 660M) :/ . When I run the bat file nothing happens (the Turbo button which shows the GPU being enabled lights up for a second) and if I start Nvidia Inspector and set the values manually the sliders just jump back to where they were. I'm using the latest Nvidia Inspector and the latest GPU driver (310.70 WHQL).
Any ideas on whats wrong?

 

Can someone attach both MSI 680M unlocked VBIOS(s)?
