GTX 770 Downclock?

[draptak]

How can I downclock the GPU's Shader speed and Memory speed?

Asus tweak doesn't provide shader speed options.

Im getting system crashes when playing a game.

I think that the card speed are set higher than the speed the motherboard currently set at.

Does anybody have an idea what I should downgrade my memory speed to ? According to Asus tweak, the default memory clock is 7010 MHz.

I have no idea how to match it to my Motherboard.

Thanks



Specs:
MoBo: AsusTEK P5QL/EPU
CPU: Intel® Core™2 Quad Processor Q9400 at 2.66 GHz
GPU: GTX 770 2GB DirectCU II
Memory RAM: 6GB
OS: Windows 7 64-bit
PSU: Corsair CX750M

download msi afterburner, and use that to manually set clockspeeds ect.

Memory/core speed on the video card have zero relation to the memory/cpu speed on the motherboard, in the same way that the type of memory on the video card has no bearing on the type of memory on the motherboard.

If you are having problems with games it could be one of several things,

1. Defective card.

2. bad driver.

3. Bad slot on the motherboard.

4. Incompatibility between the card and the motherboard (if this is it, it requires a bios update from the motherboard manufacturer).

5. Bad power supply.

Hope it isn't faulty, I only got it brand new.

Is there a way to find out if my GPU is defective without going to a PC repair store?
