NVIDIA GeForce GTX 460 - 2GB can't be overclocked?

post #1 of 15
Thread Starter 
I've been trying to overclock my video card, but running SC2 only on High preset will cause blips on my screen running at 780/1560/2000 with MSI Afterburner (default 700/1400/1800). I've seen posts and videos where people have theirs well over 800/1600/2100. Am I doing something wrong?

I currently have my CPU overclocked at 3582 (170.6 x 21 - btw if anyone has any better commendations I'm happy to learn about how I can make the CPU overclocking better) and here are the rest of the specs:

Processor: Intel® Core™ i5 760 Processor (4x 2.80GHz/8MB L3 Cache)
Processor Cooling: Liquid CPU Cooling System Standard 120mm Fan
Memory: 8 GB [2 GB X4] DDR3-1333
Video Card: NVIDIA GeForce GTX 460 - 2GB
Motherboard: MSI P55M-SD40
Motherboard USB / SATA Interface Internal USB 3.0 PCI-E x1 Expansion Card
Power Supply: 700 Watt -- Power Supply - SLI Ready
Primary Hard Drive: 1 TB HARD DRIVE -- 16M Cache, 7200 RPM, 3.0Gb/s

My card gets to 900 core at 1.087 volts, like many other people. Have you bumped the voltage at all?

I can't change the voltage using MSI Afterburner.

Ah, got it. Going to test 900/1800/2000. When I ran the TechPowerUp GPUTool's test for stability there were a whole lot of errors.

You'll probably need 1.087 volts for 900 core, most people do.

I just encountered another problem. Occasionally the Nvidia Driver wiill "has stopped working" error message me and will reset to default. Does that mean I overclocked it too high?

it means its unstable. drop the clocks a bit or increase the voltage further. i think 1.087 is the max with the stock bios so you needa flash a custom bios onto it.
