Howdy. I've been toying around with my MSI Ti4200, and my max stable overclock seems much lower than most everyone elses. I have the stock cooler on it and I am only able to hit 280 core. Memory seems to OC fine, but the core is horrible. The model is TD8X...it has 128MB of memory and 8x agp. My case has excellent cooling. Any ideas on what the problem could be? A solution would be much appreciated.
