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

I don't think the GTX 700's have a separate shader clock (at least not one that's alterable, anyway), that was a feature of older GPU architectures. If Asus Tweak does not have GPU clock, memory clock, and core voltage as adjustable settings, try MSI Afterburner or EVGA Precision X.

Video card clock frequency has absolutely nothing to do with your motherboard. Your motherboard doesn't even have a "speed," per se. All your motherboard needs is a PCIe 16x slot to be compatible with any PCIe video card of virtually any age.

Assuming your GTX 770 is not stable at its factory settings, then it is defective and Asus owes you a new one under warranty. Stability at stock clocks is a guarantee.

Thanks for the information. Do you think I should reset my BIOS by taking out the battery?
Or is this possibly a bottleneck problem?
thanks

There's an awful lot of possible reasons why you might crash when you play a game, including possibly a problem with your video card.

Resetting your BIOS is one option, although you should be able to do that simply by going into your BIOS and choosing the "Load Defaults" option (or whatever your mobo calls it). Pulling the CMOS battery is a slightly more extreme step to try if the aforementioned doesn't work.

Personally, the first thing I'd do is a clean install/update of my video drivers.
