I'm hoping that somebody can help me clear up a few things. I've got a P4 2.53 on a Asus P4PE mobo with 512mb of Mushkin PC2700. I've tinkered with overclocking the cpu by adjusting the FSB in the bios, which works just fine. When I looked into overclocking memory, the best that I can tell is that it's pretty much tied into the FSB as well. That got me curious. If the FSB on my mobo default is 133, has my 333mhz ram only been running at 266mhz ( 2x fsb)? I know that there are other factors to consider with memory ( cas latency, etc), so I've only succeeded in really confusing myself. Somebody help me!!!!!!
