Hello folks,

I'm still fairly new at the overclocking, I have had it up to 2400GHz with a 1:1 Ratio. But i'm not quite sure what effect its having on my ram. I'm guessing that as the E4300 has a rated FSB of 800 and an actual of 200 that on a Ratio of 1:1 my ram is running at 1064 is this accurate? And if it is would changing to something like 3:4 Ratio have a big effect on performance?

The big question is if the RAMs holding stable at 1064MHz (assuming im right about the calculations above?) is the 1:1 Ratio Better? And if it is is it worth the calculated risk?

Thanks in advance for your answers folks!

if you are running the cpu at stock speed with 1:1 ratio, the ram is running at 200mhz, half what its rated for. you can overclock the cpu fsb up to 400mhz, and at 1:1 ratio, the ram would be running at 400mhz as well, which is its rated speed. such a high increase however would require careful steps to make sure the cpu will be stable and if your mobo will handle the fsb increase. if you were running the cpu at 2.4ghz with 1:1 ratio, the ram was at 266-267= ddr2 533

So is a ratio of 1:1 preferable over other ratios? if yes, why? From what i've seen it appears that the MHz in this case 400MHz controls the rate of speed that the processor talks to the ram. And the timings work within the ram so (and im not sure about this) if I was to keep the ram at 400MHz and lower the timings I will improve performance, is this right?

Thanks!
