I am using a Old system which is 4 years old and it assembled PC. I have a DDR2 1GB 667MHz and another 2GB 333MHz. Before I was using 1GB RAM on XP and now using Win7 and I removed 1GB RAM and put 2GB for Win7. I am using Asus P5GC-MX 1333 mobo with Intel Pentium D925 and a PSU 400W. As processor can run much higher speed than what I am getting 185.2MHz. So First of all I am using a Intel stock cooler. I don't want to spend money in upgrading Cooler or CPU etc. So can anybody help if I can increase CPU speed because I think I am running my CPU at very low speed.
I have to change the setting in the BIOS from Auto to Manual and I lowered the CPU FSB from 200 to 185 because I was getting BSOD when I was running windows. I think my RAM 2gb 333MHz is the problem . What if I use 1GB 667MHz RAM on win7 ? What about the speed if I use the 1GB RAM is it recommended to use 1GB to run applications and the OS?
 
At a FSB of 200MHz, and w/ the lowest DRAM multiplier available being 2.66 on the 200 MCH strap, the effective DRAM frequency = DDR2-533MHz. So you shouldn't have a problem running that RAM at the default 200MHz FSB. The DDR2-667 (PC2-5300) can be run on the 3.33 DRAM multiplier at the default 200MHz FSB. Since that board only utilizes 2 x DIMM slots, populate both w/ the 1GB of DDR2-533 and the 2GB of DDR2-667 in single-channel, but make sure the DRAM multiplier is set to 2.66.
