Higher Fsb or multi?

post #1 of 4
Thread Starter 
I know loweing the multiplier increases the ram speeds while u increase the fsb. question is this would it be better to use higher fsb or higher multi? The reason im asking is this i finally hit a wall on my proc it seems no matter what i do i cannot reach 3.0 oh well. right now im at 2.94 with dfi ultra-d the best speed i can get with low temps i can push it to 2.96 but crazy temps. so im wondering since i bought a new ram pc4400 its rated to go 277 and with my current oc Fsb 268 x11@ 2.94g, dram 200 (1:1) at 268mhz so im under clocking the ram speeds. i can try this settings to increase my ram. fsb 294 x10 multi @ 2.94, dram 200 (1:1) @ 294mhz. if i do use this settings what are the pros and cons to it?

If your ram is stable, then there's no cons. Your ram is running quicker and your CPU speed is the same.

Well last night i tried running memtest test #5 with no errors (5 loops) @310mhz how many loops should i run to know if this is really stable? and having a faster ram is better than having a faster fsb?

I wouldn't bother with memtest, it's never found any errors for me. If you've got a game like Quake 4 or CoD2, run that. Normally picks up any instability with the ram nice and quick and it's much more fun than watching memtest. Found that those 2 games, in particular are great for testing system stability.

The AMDs no longer have an FSB, they have HTT. On a system that has an FSB, you raise ram speed by increasing the FSB (or HT on AMD systems). Lowering the CPU multiplier only affects CPU speed, nothing else.
