Unstable computer at 500 1300 (nVidia 7800gt)

post #1 of 7
Thread Starter 
I just received my eVGA 7800GT that I bought used on eBay. I'm willing to start overclocking it. I tried to put the settings at 500 and 1300 but my computer was always crashing...

I'd like to find the max stable clocks of my card. Any tips regarding this?

And is it normal that my computer crashes at only 500 1300? Could it mean the previous owner oced it too much or something?

1300 seems way too high for the mem clock on that card. I have mine right now at 502/1180. Try using coolbits 2.0 and 'detect optimal settings'.

1300 on the Memory is to high.

Download Coolbits Open it up and it will edit your VC registry.

Next right click on your desktop-->settings-->advanced-->7800gt--> clock frequency--->3D overclock--> Detec optimal settings

It also reaches 78 celcius during intense fps gaming... (FEAR multiplayer) is this kind of high? The threshold in at 115 celcius...

Yes thats too high, cool bits says 115, but you shouldnt go over 80 C.

78 C is perfectly fine, you dont have to worry until over 90 C or so, and even then its not "bad". 1300 memory is more than likely what caused the instability. I'm still running mine at stock 470/1100 but I'd say go to 500/1200 and see if it works there. The sweetspot for many 7800GT's seems to be around 490/1180.

Also, your power supply might be struggling. That powerful of a card might need more than a 420w.
