    Well as you can see the details on my rig are below and I usually get cpu temps that rest between 29-32 deg. I havn't touched much in my bios exept for the multiplier which is resting on 11x and the CPU external freq is @ 200 MHZ, apart from that is pretty much untouched, any suggestions/methods on how to crank it up further? (trying to keep it as stable as possible).

    try to raise the FSB little by little until you see your system isn't stable you you put it a little lower. Don't forget to check the temps also, you don't want your cpu to fry :hammer:

    Dude with your HSF combo (SP-97+Vantec Tornado) you definitely have a lot more headroom to OC. Go for it!

    I would suggest not raising the FSB much higher than 210 though, since your memory PC-3200 works at 400MHz. Try the following:

    - Your Barton is definitely unlocked since you have been able to lower the multiplier so I would first try raising the multiplier to 11.5x200MHz to get to 2.3GHz. Raise Vcore to 1.70V and check for stability using Prime95. It should run without reporting errors for at least a couple of hours. If CPU temps peak at less then 50C during Prime95 torture test you should be just fine.

    -If you want to be more agressive try raising the FSB in the smallest steps you can. When Prime95 reports errors after less than an hour, leave the FSB a couple of settings back to ensure stability.

    Note: You could also try relaxing memory timings a bit or raising memory voltage when working above 200MHz

    Hope that hepls!

    Go for 11x220, don't listen to him.

    Your system is just about guaranteed to do it. You will need to increase vcore and vdimm when necessary.

    No sense in raising stupid multiplier when you have spent money on a decent system that you can get more out of.

    It is clear that if your components can handle it raising FSB is the better choice that's obvious.

    I just meant that if you want to ensure stability without pushing the memory a balanced combination of raising FSB and multiplier is a more conservative way of OCing. I only suggested it because he seemed more concerned with stability.

    You should also note that the total processor speed calculated by multiplying the FSB x multiplier.
    CPU speed will represent how much information the CPU can produce wheras FSB represents like someone once put it the width of the highway on which the information is distributed. Having a super high FSB is therefore not necessarily the best way to OC.

    That's the reason I suggested raising the multiplier to 11.5 and then start raising FSB until he reaches the unstable point. That way the processor is reaching a certain speed without straining memory too much. PC-3200 memory does have a headroom to work at higher than 400MHz speeds, I agree, but telling him that raising the multiplier is stupid and it's not. Only raising multiplier without raising FSB is stupid, but balancing the clock speed while raising FSB from 166 to 205 or higher with a 11.5 multiplier isn't.

    I still recommend 11x220, most PC3200 memory can do this. It WILL be faster than using a higher multiplier and lower bus speed, and just as stable. 220 isn't really pushing it that far when you consider this:

    I guess I stand corrected as far as the memory goes, but what FSB/DRAM ratio are you using to set those timimgs?
    Are you setting it 5/5 or 6/6 or do you have it with a different ratio, because PC-2700 is specified as 333MHz memory, so if you had them on 5/5 or 6/6 that would mean your memory is at 440MHz.

    And by the way what's you memory voltage at? I have PC-3200 Kingston Hyper X and the lowest I have reached with a stable system are 2.0-3-2-9. If I set 2.0-2-2-9 it won't boot. I have only gone as high as 2.7V on memory though.

    That is the frequency of the memory. That's 1:1.

    Its not mine but its at 3.45v or so.

    DDR333 2.5-3-3-7 @ DDR542 2-2-2-5
