I admit I never really knew a ton about RAM. I just knew it was the thing that would either allow me to overclock more or would stop me from being able to, and that it should be stable to prevent BSOD's and other issues with stability. So I have 2 GB of 1066 MHZ RAM and am just looking to get my system to run at 7x400 for 2.8 GHz with the system in my specs. Which configuration gives the best performance? A: Ram at stock settings, 1066 MHZ 5-5-5-15 B: Ram at 800 MHZ with tweaked timings whatever they can be lowered to C: Ram at higher than 1066 MHZ with same or looser timings. I read a rather detailed "bible" about RAM but it was lengthy and a bit confusing. If my FSB is at 400 MHz, does my RAM perform the same at 800 MHZ 5-5-5-15 vs 1066 5-5-5-15 or is the 1066 better?
