Just built my new gamer and decided to use an AMD 4200+ Athlon X2 cpu that I found on sale. My Codemasters auto racing games go into "hyper speed" and are unplayable. Searched some forums and found that this seems to be a common problem with the X2 cores. Most of the fixes that I have read suggest that you disable one core, I would rather replace my cpu with a single core than disable one core. I checked the direct X and the bios and everything seems to be working correctly. Any suggestions would be greatly appreciated. Thanks.
