    yeah i went frm 1.525 to 1.535 but no change do i need to go higher? ive seen a person get 3.8Ghz on stock voltages, y cant i?

    Not all processors were made equal, including ones that are the exact same model. My athlon64 goes from 2.2 to 2.5 before I can't go higher. I'd recommend increasing the voltage a little more.

    3.8ghz on stock volts? I highly doubt it, even on sub-zero cooling.

    Dont reference things to what you "saw" someone hit.

    No proof there. Just a picture of cpuz at 4.3 which doesnt mean much.

    no, but i know the guy in real life, and ive seen that comp running there, so dont say im wrong, anyway, apart from the voltages what else could this be?

    There are many factors you have to take in to consideration. It might not be your CPU that's limiting your overclock. Maybe your motherboard just can't handle such a high FSB. Or maybe you should loosen timings/ clock speed of your memory. Maybe your N/B chipset is overheating. Lots of things could be happening.

    ok, temps are 39C full load and 30C on idle on teh cpu, and 30C on n/b idle 32C n/b load, so i dont think thats it, the timmings are at 2.5-3-3-6 which are default for 200MHz, wehn the memory is only @ 194MHz and i dont thinks its the mobo...

    When I overclock my computer, i increase the PCI-e voltage and that allows me to reach higher FSB clocks. Is there such thing as an AGP voltage?

    yep, itz currently at 1.50v (well it was the last time i checked) and the pci/agp has a lock at 33/66

    Well if you know the guy in real life I would imagine he would be a great person to ask as to how to overclock it. If you've already asked him, what did he have to say on that matter?

    up the voltages like u, ive been at school when ive been asking u these questions, im now home so...

    ok i increased the voltage frm 1.525v to 1.550 and bumped it up 2 3.4Ghz, it worked! yes, but the temps were going frm 39C at 3.3 to 48C at 3.4. So i decreased the voltage by 1 stage which put it at 1.535, success! but the temps were the same, i droped it down to stock voltages again, and....No luck, crashed in first test of p95 so.... i think 48C is to hot 4 me, ill just leave it untill i get water, then 4GHz HERE WE COME!!!!!!!!!!!!!

    anyway, thx 4 ur help guys, u guys are great, as always...

    Also "burning in" your cpu might help too, i guess it did for me ===>

    Still at 1.525 stock voltage and the only thing holding me back is my ram :/

    Well burning in components like cpu and ram means working them at 100% continuesly over a certain period, a full day or so...

    For example, my ram wouldn't even do CAS 2 at DDR200 when i first got it even if i pushed the Vddr at my mobo's max which is 2.8v.
    After a few days burnin it now runs at 2-3-3-5 at DDR213 error free with 2.65v.

    Edit: some ram chips respond to burnin and voltage increase more than others, mine, TCCD based chips r well known for responding to both burnin and high voltages, up to 3.2v at which my ram can do DDR250 (Unfortunately my mobo can only give up to 2.8v :( ).
    While others don't respond as much....

    well give me a program that will work the cpu and ram at the same time at 100% (or give 1 program 4 each if u have 2) cos p95 only works the cpu at 50%

    Then u r not setting it to work properly.....
    Prime95 for the cpu and Memtest86 for the memory, both programs utilise 100% of each respectively if your run the appropriate tests.
    It should be pretty straight forward tho, just run the torture test in Prime95 and leave it alone.

    which one is the one i use for p95? and on memtest (the window version) i got 1024 memory, do i run 2x memtest programs (512mb on each) or how much on each test? thx
