Clockrate question

post #1 of 6
Thread Starter 
should I do a 2000 FSB (500) with an x8 multiplier or an x9 with 1800 FSB (450)

I run my ram in syc mode so at 500 FSB RAM runs at 1.0ghz and its stable at 1hr with x8 multi

or should i use my higher multi?

I'd say put the higher memory speeds to use. But that's just me, it makes sense though.

well I can run an 8X multi and my CPU can only be at 4.0 GHZ because i dont get a .5 multi


OR i can run at 4.35ghz with x9 multi but my RAM sits at a lower 966 mhz

However you get your processor to the highest clock speed gets my vote.

I've never seen any appreciable app performance differences (synthetic memory bandwidth tests would be a different story, but I'm talking real-world here) between any conceivable combinations of fsb*multi which result in the same processor clock speeds. In other words, 8*300 = 6*400 in 99.9% of whatever you would be doing, and differences, if any, would be small. And even if you kept 1:1 on the memory, you'd still have = performance in like 98% of cases, with differences, if any, being small.

Memory speeds/latencies, in general, don't affect your real world performance much at all either, not with intel architecture(s), and especially not in benchmarks that are not specifically testing your memory numbers. That is to say, as long as you aren't using something like a 1:2 mem:fsb ratio or something ridiculous like that. As long as you're within 30% of 1:1, your exact mem speed ain't gonna mean ****.

One thing that ALWAYS makes a difference though is raw clock speed on your processor. So that's why I say do whatever it takes to get that the highest, and whatever memory concessions you have to make (if any) will be well worth it.

Just my $.02 based on my experiences ...

I would choose 9x ... try to keep fsb as closed as possible to the default, just my thought
