Higher FSB / RAM better than higher multi?

post #1 of 7
Thread Starter 
I am curious as to what is the better situation...a higher multiplier with a lower FSB/RAM speed, or a lower multi with a higher FSB/RAM speed...this x6800 seems to like the lower multi (stock 11) with higher fsb, at lower vcore.

Higher FSB. That way your RAM & Chipset are running at the higher speed, if you have capable ram that is.....

I have 450FSB x 8, RAM 1:1 900mhz

The FSB is the communications frequency between the entire system. The higher the FSB the faster the system is. With a higher multi, the FSB isn't pushed as far as it should be.

Overall, Intel systems will benefit greatly from higher FSB and ideally a 1:1 ratio between the cpu and ram.

unfortunatly, I can find no settinh in my bios to allow me to change the ram speed ratio to FSB...if I change one, the other automatically changes to stay at a 3:2...

I do seem to notice better system performance with my multi at stock, and my fsb at 300 mHz and ram speed at 900 mHz, vs multi up and FSB at stock.

Plus I can run with lower voltages.

All I will say here is that Intel processors suffer from deprived bandwidth in comparison to AMD processors with the same installed memory modules (by up to almost 3.5GB/s)

I would suggest that you use a lower multiplier and a greater bus speed to help compensate in memory bandwidth

Your choice though

Even though greater bandwidth does dramatically help with cache errors, where the cache is not great enough to store all the required data.

what about a small increase in multi, like to 12 instead of 11, and then raising the FSB?

edit.....I think I will stick to stock multi, as I have gotten a lot better results recently with ramming the fsb..

from my understanding is best to get the CPU as clock speed as you can but if you can get 3.0GHZ at 200FSB vs a 400FSB you would be best to get the 400FSB and the lower multiplier. don't really worry about what multiplier number you use as the multiplier in itself isn't that big of a deal
