View Full Version : Infinite Loop with 8600GT

CPU: AMD ATHLON 64 X2 4400+
RAM: 2GB DDR2 667Mhz, 1GB DDR2 800Mhz
VIDEO: ASUS NVIDIA 8600GT TOP (http://www.asus.com/products.aspx?l1=2&l2=6&l3=514&l4=0&model=1678&modelmenu=1)

Stock speeds:

Core - 600Mhz
Shared - 1458MHz
Memory - 2016MHz

I've got the infinite loop problem when I try to overclock my video card (I should mention it's rock-solid at stock speeds). It doesn't really matter if I overclock it by 10 or 100Mhz - it still locks up the computer after ~10min. of gameplay. Idle temp is 48-50C, ~75C (660Mhz core/1603Mhz shader) at high load, so I'm assuming temperature is not the problem. I've bought an Enermax NoiseTaker II 480W yesterday, replacing my 400W Codegen PSU, which unfortunately didn't fix the problem. I've tried various drivers, different OC software like nTune, RivaTuner, Asus' SmartDoctor, but to no avail. I tried swapping RAM sticks, disconnecting drivers, playing with the BIOS settings and nothing really helped.

You guys are my last hope. :)

i wonder if its a voltage issue to the card....i remeber flashing the bios on a few cards that i have edited the bios with nibit to give just a tad more voltage and it stablized and even let me oc farther....just a thought

I would definetely try that. I'm not an expert, so would you guide me through the first step as for what software I could use to flash the BIOS, how to edit the voltage, etc.

Thank you.

ОК, I got it. What voltages are safe to select here? And what about the Exact Mode? It looks like 1,32V is the highest voltage rating I can select, but is it safe?
