8800GT overclocking help.

post #1 of 19
Thread Starter 
I'm using a Duo-Orb cooler. My temps are at 45c and my 8800GT is at 670/1800/1022 in rivatuner. Load temps are 49c. 51c in Crysis. Basically amazing temps, but when I go anywhere past 670 the display driver stops functioning. The card has room for WELL past 670. Even the new drivers don't work. The .19's.

What are my options? I know Nvidia's Vista drivers are EXTREMELY senstive. Are there modded drivers that are good that work with OC's? Omega didn't work.

What brand is the 8800GT? I found my EVGA GT clocks better than my Galaxy one.

Its EVGA 512MB. Replaced the stock cooler with a duo.

Drop your Shader down first, then you can work on the core.

Trying 700/1750. But if I drop it I'll lose performance. Shader is more important right?

Memory is I think, but very few people can actually pull more than 1000 on the memory.

I've never had problems until 1050 on Rivatuner with memory. I have it on 1030 now, with no issues or heat problems.

670 to 700 with down to 1700 on shader wasn't stable. I guess 670 and 1800 is my max overclock? but the temps are so good I thought I could go so much higher.

Temperature isn't always the concern for Video cards. Cards are limited by their own unique overclockability just like CPUs.

I was hoping I wouldn't have a crippled GPU. Since my e2180 won't EVER get past 3.1Ghz stable. I guess my 8800GT is the same at such a low clock. Ah well. :/
