I want to tweak my ram for better performance. I have 2x 256 of crucial pc2100. I know you have to change some timings in the bios and I always see people mention their settings (ie. 2-2-2) and I have no clue which timings they're talking about and if lower or higher number is better (ie. 2-2-2 vs 2.5-2-2). In my bios (kg7 raid) I have nearly 10 different tweakable timings, which ones are you all talking about / which ones do I change?
