    Default I have a GA-P35-DS3L (rev. 2.0)What can I achieve with overclocking a Q9550

    What are the FSB limits on a GA P35 with a quad core. I seem to not be able to post with a fsb at 470 with my FSB V+3 and MCH V+3 the CPU multiplier at set at 6x for testing, the memory is set at 2-2 it OCZ 1066MHZ and there is no posting at that FSB

    check the other recent 775 cpu post.
    For long term overclocks.
    p 35 set, some asus boards and quads seemed ok at 2000-2080 fsb.
    Gigabyte ep45 ud3 and 775 quads seem to go to the 480-510cpu ref(1920-2040 fsb) range
    45 ds3 dont seem to do as well.
    35 dsl (without the designed 400mhz cpu ref ) seem to go lower.
    Either way Q9550 /any quad 775 500(2000 fsb) is the usual reliable maximum posted here.
    Current Systems:

    Asrock p67 Extreme6.............. Gigabyte EP-45 UD3 ...................... Gigabyte 73 PVM S2
    Intel i5 2500k 4.8ghz................ Intel Q8400 3.8ghz......................... Intel D820 2.8ghz
    Zalman 10x cooler.................... Coolermaster V8............................ HP cooler
    8GB Gskill ripjaw ddr3.............. 4GB Gskill PI ddr2.......................... 4GB samsung ddr2
    60GB ssd/500GB HDD .............. WD 1TB hdd.................................... Seagate 160GB hdd
    GTX 460 1GB x2 SLI ................. Msi 9600GT 512MB(died) ........... Onboard gx
    Win7 64 ,750w psu(ocz)............ Win7 64 ,520w psu,seasonic...... Win XP pro ,400w psu

    HEC 6A34 case . ....................... Jeantec R2 case............................ Packard Bell case

    hoping to upgrade to http://www.thinkgeek.com/stuff/41/habicase.shtml

    Can you post the full settings you are trying that fail, link to a template to give us your settings is in my signature.

    Also please tell us what BIOS you are using, and provide a link to your memory or the model #

    You mean Performance Enhance = Turbo? If so this tightens internal memory timings you cannot access, and tightens up a few NB timings.
