There are people who have overclocked 650 single and 650 sli. requires an unlocked bios. the unlocked bios you can find in this forum. as for the overclocking a search for y500 sli overclock should get you the information your looking for.

I've only had success overclocking on the 310.90 drivers so far.

I'm running 1100mhz on the core at the moment without any issue and only a minimal increase in GPU temp.

This gave me another +3500 P score in Vantage and I saw a noticeable improvement gaming.

Looks like it will go higher, I'll likely play with it more this weekend and toy with the memory clocks.

Hey guys, even after flashing the unlocked V1.05 Bios, I still can't go past stock clocks on my GT650M SLI? Anyone have any idea on why this would be?

What are you using to overclock and what nvidia drivers?

I've only had success with the 310.90 drivers and Nvidia Inspector

Using Nvidia Inspector now and 310.90 drivers. However, I am only able to overclock one video card? How do I get the clocks up on the second card?

there is menue at the bottom where you can choose the second card, if your doing it with a batch file, the parameter which changes is the first one, ex. setClockOffset "which GPU",parameter2,parameter3 / 0=main GPU 1=additional GPU

Overclocking support is coming soon. I found a solution to do the BIOS mod for the second card. Please refer to one of the top popular threads and stay tuned. Use driver 310.90 with nvidia inspector batch files in the main time.

Overclocking is not worth it compared to using older drivers. Specially with SLI. You may get equal performance in the end because of driver optimizations. Keep that in mind.

svl7 didn't modify vbios of modded v1.05, you have to try modded v2.02. See his thread for details.

not true man when i bump my clock speed up by 250 and memory clock up by 500 i get bigger fps improvements than the driver optimizations

Did you face any throttling when doing benchmarks like msi kombustor?

650M SLI Overclocking can be true,through using nVidia Inspector on the drive of 310.90.post-12300-14494994995455_thumb.jpg

It could work but only to 924Mhz. I tried it. Seems something wrong with the bios and needs to be unlocked.

Guys. You can overclock the video card even without the modded bios. What drivers are you running wuzongh? If you run the 310 drivers you'll be able to overclock to at least 1150/2300
