I always hear that a 1:1 ratio is the best, but I have a different kind of old school build and I'm getting better fps in Heaven benchmark with 3:4. The CPU is the bottle neck on my machine. I keep RAM timings tight in either case and the system is stable with 4 gb of DDR2 667 at 3-3-3-10. What would you suggest? Should I not worry about a 1:1 ratio and just get the RAM as fast as possible, because I can even go 3:5???

ASRock P4I945GC w/ Pentium 4 Prescott 3.4 OC ~3.76 Liquid Cooled. (Low to Mid voltage)
4gb DDR2 667 @ 295mhz 3-3-3-10, 3:4
Geforce GTX 560 OC w/ 2gb (Async)
120gb Kingston HyperX SSD

Thanks for your time.

PS, does anyone know of a sock 478 board that has BIOS allowing for vcore increase??? I can't find one, only sock 775. Yes, I will build an up to date machine eventually, but I wanted to learn everything about OCing using the die hard P4. Thanks again.
