    :lol: Hey I jst overclocked my A64 FX-51 to GR8 exetent ie to from 2.2Ghz to 2.8Ghz by raising HTT bus and increasing processor multiplier .
    Its amazing and fantastic. But my friend GR8prash has got an Opteron processor on ASUS SK8N(I Have GIGABYTE GA-K8NNXP-940). both are based on nF3 150 and loads of OC feature.

    BUT HE SAYS THAT HIS OPTERON CAN BEAT MY A64 FX-51 IN ANY BENCHMARK. :evil: IS THAT TRUE????

    This boy is telling a lie A64 FX-51 is not his. He has a AMD64 FX-53 on MSI K8N NEO2 PLATINUM. And the PC he overclocked is of his boss!!

    and yes I am tru MY OPTERON has 3 HTT bus Links instead of his boss AMD64 FX-51's one.

    moreover u have ECC reg. RAM which is slower where as I have unbuffered RAM which helps in overclocking to higher extent. again i win due 2 higher HT link BUS speed ie 1000MHZ than 600MHZ of urs

    HT BUS speed rarely matters as while OC u have to decrease it to 600Mhz or even less. whereas OC opteron is much easier as instead of decreasing HT bus speed all u have to do is raise HT bus voltage. moreover with 3 HT BUS 4 different controllers my opteron can easily beat out ur FX-53 as there is a separate HT bus 4 handling AGP BUS(ie GRAPHICS), Another one for storage and the third one is for RAM

    First of all I disabled 'cool n quiet' from BIOS. I increased
    HT(HyperTransport) Bus frequency from 200Mhz to 216Mhz,
    at the same time I increased CPU multilplier from 11x to 13x
    thus resulting speed was 2808Mhz(~2.8Ghz). Before OC(overclocking)
    I checked the system's performance. MY boss's PC configuration is
    as follws :
    AMD ATHLON 64 FX-51
    ASUS SK8N
    2*512MB CRUCIAL BALLASTIX ECC REG. CL2.5 PC3200 DDR SDRAM
    ASUS V9950/TD/256 GOLDEN SAMPLE
    2* SEAGATE 80GB (7200 RPM) SATA HDD IN RAID0 CONFIGURATION
    SONY DVD-WRITER DRU700
    ANTEC PERFORMANCE PLUS 660 AMG

    As I pushed the PC to a whopping 2.8Ghz(ie 27.27% OC). More OC
    was certainly possible but due to lack of a dedicated chipset
    cooler(only heatsink was there on ASUS board) and a CPU cooler
    from a reputed company, I had 2 limit my OC. As a working PCI/AGP
    lock was present (although nForce3 150 refernce board carried a
    working PCI/AGP lock but most boards based on this chipset didn't
    featured it 4 sum reason but ASUS and Gigabyte did carried) OC was
    a breeze on this PC. I increased the RAM frequency as well 4 system
    stability (RAM sticks are superb and remained always cool). After
    overclocking CPU it was now the turn of GFX card
    A the GFX card based on GeForce 5900XT had a 256-bit memory intrface
    OC it was a breeze.
    I pushed it from 475/895Mhz stock sppeds to 512/1000Mhz. It became even
    better than a GeForce 5950XT(clocked at stock speeds). ASUS SmartDoctor
    enabled me to keep an eye on temperature and it was the ony tool I used
    4 OC. ASUS must be praised 4 its brilliant cooling solutions on cards.

    Benchmark details are:

    Stock speed CPU SiSoft Sandra 2004 pro OC CPU
    9125 CPU Dryhstone 11566
    3448 CPU Whetstone 4388
    16321 Multimedia CPU Integer 20772

    No need to increase Vcore & VDimm ?
    What about chipset cooling ?
    :roll:



    Doesntthe 940Pin Athlon FX require ECC DDR too?? :roll:


    How was that done? wasnt your RAM running synchronous with the Bus?
    are there options to increase RAm speed by small steps of1-5MHz inthe BIOS? or is there a FSB/RAM Ratio option in the BIOS?



    I dont think there even exists a chipset called 5950 XT,does it?

    Why dont you twogreat overclockers post screenshots of your achievements? Otherwise it is hard to believe your claims.
    Also, what cooling did you use for your overclocking?
