How many of you have been unable to get the maximum performance of your system? Experienced nvidia driver crashes when playing on SLI?
A lot have tried:
- Different/older drivers
- Modded BIOS and vBIOS
- Undervolting CPU and/or GPU
- Physical cooling mods
- Underclocking the Core clocks of the GPU
- Setting the TDR delay limit to a higher value
- Different Nvidia Control Panel settings
- Different OS's
I think I finally have the solution for you.
Download Nvidia Inspector - I use version 1.9.7.2 even though there are newer ones (it's the only one that lets me force P-states)
Open up Overclocking and choose your second GPU
Set the Memory Clock offset so that your effective Memory Clock equals your RAM clock. i.e My RAM runs at1600MHz and my default GPU memory clock is 2700MHz, so i put the offset at -1100MHz.
Apply Clocks and Voltage
The app would need to be started every time you want to play though, so please be careful of that. You can make a shortcut of the clocks using the program and then just start the program and execute the Clocks shortcut before playing.
I had been struggling with playing CS:GO on SLI for 1.5-2 years maybe. I had resorted to playing with SLI off, but always knew I could get more FPS if I just managed to get SLI to work. And now it does. Enjoy your 300 FPS, guys.
My hardware:
Lenovo y510p Laptop
Matte LCD screen (overclocked to 80Hz, if you're an owner of the glossy screen, you can OC to 100Hz)
i7-4700MQ
2xGT755m (I don't know if this will work for the gt750 guys, but doesn't hurt to try)
Software configuration:
Win 8.1 64-bit
Nvidia 364.72 driver (without GeForce Experience and PhysX)
Nvidia Control Panel settings are default
ThrottleStop 7.00 (A handy little program that disables CPU throttling when gaming, it has no part in the fix though, you can use it to get maximum performance out of your system, recommended to laptop users)
