    Question 1:1 or 5:4 for intel

    Hi i'm new to this forum.

    I was wondering what kind of overall performance difference(benchmarking and real time apps, and also gaming) will i get if i ran 280 (3-4-4-8) fsb 1:1 as opposed to 224 (2-2-2-6) 5:4 on an Intel platform?

    I currently have a pair of BH-5 and i'm considering getting a pair of PC4200 if i there is a significant performance gain.

    Synchronous busses tend to be a lot quicker, but there are circumstances in which there are not.

    I would think in your case, 1:1 would be pretty good.

    thanks for the quick reply. Is it true that games tend to perform better ie higher fps with tight ram timings?

    I've been reading around and some sites say it is and some say it isnt. Anyone able to compare for me please?

    It really does depend! More mhz give you more data throughput, but tigher timings gives you less latency.

    It's a juggling act IMO.

    My suggestion is try both ways and see which proves the best...

    its all about finding the balance, on an aggresively overclocked rig 5:4 is better than 1:1 cause the mhz/fsb gain/loss becomes more favourable mhz wise.

    Mate, if you already have BH-5 running 2-2-2-6 @ 224, then I really doubt it's worth the expense of going to PC4200. Here's the Hexus review that compares the performance of some highish latency PC4000 with some low latency PC3200. The difference in real world benchmarks is sod all. Save your money for an upgrade to an X800 or 6800, SCSI hard disk or whatever.

    intel is fine with an asynchronous bus, it's amd32 that dies on its ass

    Well i was asking mainly because i am able to get the PC4200 cheap and sell BH-5 to gain a little extra cash for maybe some other upgrade.

    You guys still think its worth doing it?

    You MIGHT gain in some applications like 3dMark2003 and definitely lose in some apps like 3dMark2001.
    Speaking from experience, low-latency usually gives overall better (snappier) feeling to system.

    At high FSB's 1:1 with relaxed timings vs 5:4 with tight timings, 5:4 wins most benchmarks.

    Now if you were at a much lower bus speed where 1:1 w/tight timings was possible vs 5:4 tight timings it would be a much close match with 1:1 probably winning.

    Keep what you have. BH-5's are the shiznit. You'll regret getting rid of them, especially if you upgrade to a 939 pin mobo and can only reach in the 220FSB range... you'll want those low latency mods back.

    haha...thanks. I think i'll keep them. Now need to get better cooling for my ram as i'm running them 3.2V 24/7
