Thread: fsb & multiple settings confusion

    hello everyone,
    I have been browsing the forums for a few weeks now since I made my switch of allegiance from intel to amd.(steep learning curve )
    I have avoiding asking newbie questions by searching and reading as much as I can on the subject of FSB and MULTIPLYER settings.
    I have have my fsb at 168(2 over default) and mutiplyer set at 13(default) giving me a speed of 2184.This has run and passed benchmarks etc with no problems whatsoever.
    The problem is that this morning I put my Fsb up to 170 and kept the multiplyer the same(hoping for 2210) and I got the system failed memory test message.
    Reset the cmos and rebooted setting the fsb to 170 and the multiplyer to 12.5 and I still got the memory test failed message.(even though this should be 2125 less than my stable settings from before)

    I have my memory timings set at optimal so I haven't overclocked the ram.
    What am I missing?

    What do you mean optimal?
    You could try to slack the timing to get more fsb (upper the numbers) .
    I think the best is to put the multiplier real low (like 8) and see what max fsb you can get... but i doubt your memory will let you overclock that much, you are already at max fsb(333 mem), what brand is it?

    Hope that helps! :cheers:

    Lock AGP/PCI to 66/33 mhz and lower the multi to 10. Set the divider to 1:1 and it will do 200fsb easy, then take it from there. You will be limited by the 2700 RAM.

    in the bios you have options for memory timings etc.
    I have these set to optimal(rather than aggressive).
    My memory is crucial.

    From what Iíve read here and else ware. Youíll get better performance if you run both the fsb and memory at the same speeds. You may have to set the memory timings manually rather than optimal just depends.
    For example at 333MHz mineís set at 2-2-2-6 but to get to 400MHz I set it to 2-3-3-7 and if I chose optimal it would set the latency to 3 and it wouldnít boot. Forcing me to reset cmos. You got to play around with it some times to see what works best for you.
    Note: You donít want to have to reset cmos too many times as you can corrupt your Windows installation.

    Tried that and it still gives me"system failed memory test"
    I have Fsb set to 200 and multiplyer at 11 now and it seems stable.
    As soon as I take any of the other settings off auto or optimal it fails memory test.
    on optimal my memory settings are 7-3-3-2.5(t).When I changed it 2(t) and set the memory at 100% it failed memory test again.
    I am getting a bit bored of taking the computer casing off all the time and Mrs Satan knows that I am doing somrthing wrong by the look on my face.
    If I am a failure in front of her on my chosen hobby then I am afraid she might leave me and marry an I.T professional;)

    nope I haven't tried changing voltages yet.
    I am not sure I have seen an option for it only vcore.
    Will that help or am I just gonna fry bits of my new machine?

    Well seein' some temps would help but in ya BIOS under Power BIOS Features (assumin' that the ASUS BIOS is similar to the EPoX one), it won't hurt to up the CPU voltage to 1.75v and the DIMM voltage to 2.75v.

    Are ya usin' the standard retail AMD cooler? :?:
