I just overclocked my OEM GeForce 4MX (440) using Graphiccelerator. I only upped the CPU clock about 7% (from 270 to 290 MHz) and the memory clock about 15% (from 200 to 230) but I have not installed any sort of additional cooling. The result is noticeable to me when playing MOHAA on-line but more objectively, using "timedemo" on Q3 Arena running a demo I recorded some time ago yielded about a 12% improvement in frame rates. Any of you overclocking experts out there have an opinion as to whether I am running too fast for no additional cooling? I read in an article that they were able to crank the GF4MX-440 up to 295 MHz (CPU) without additional cooling. One thing was very puzzling though: They list the CPU speed on the card they used as 270 MHz which matches mine. The memory speed on their card was supposedly 400 MHz while mine was 200 MHz. Could other cards using the same core chipset really vary so much in terms of the memory speed?
