Which is better performance?

[yellowb]

Well, I was able to get my E6600 overclocked to a FSB of 378. What would be a better performer between these two scenarios. The E6600 at 378 FSB and 3.4 GHz with DDR2-756, or changing the multiplier to 8 and run at 400 FSB and 3.2 GHz with DDR2-800? Not sure if having the extra processor speed is more valueable, or having the full capacity of the memory. Thanks.

CPU speed rules in most all situations, having said that, I don't hink you'd be able to distinguish the difference in any typical usage.

Here @ my E6400 7X450 was better than 8X400, so I would say you'd better go for the lower multi... This is because the ram is running on higher speeds, and your frond side bus is much higher.

On my machine it's only half a second faster, but whit 50 MHz less... So it would be about a second faster in SuperPi 1M if I would also bring it up to 3.2 MHz with the X7 multi.

So what I'm trying to say is: Look at what speed your cpu stays cool enough for you, and then you can play around with the multi, en the memory dividers... just test what's fastest... and keep that one...

But if it's only for normal use, I don't think you will have much afford of the lower multi...

CPU frequency will have bigger impact than the memory frequency and or timings. Just to be sure you should bench both settings as see for yourself which is better and stable.
