I'ts upgrade time for me! I ordered a DFI LanParty UT nF3 250Gb, AMD Athlon 64 2800+ NewCastle, Zalman CNPS-7000B Cu. Last week I received all the parts. Last weekend put it all together.

Big thanks to the guides at:

The 2502 MHz OC is stable. While the 2601 would bring out errors in Prime95 after 4+ minutes (temp was max 64C @ 2601MHz). I suppose that 2601 MHz could be easily reached with watercooling or something like the Thermalright XP-120.

The magical setting I'm using is: Dram Frequency Set at 166(MHz)(5/06). Which means that when my HTT is 278. It gets multiplied by: 278*(5/6) so the FSB becomes 227.
I'm afraid my TwinMOS ram doesn't want to go any higher than 230MHz (even at 3.1V), it's still quite a nice clock - 460MHz maximum :)
Maybe one day I'll buy something like the OCZ PC3200 Platinum Rev2 and push it to 600MHz..

I have a question, what should my LDT/FSB frequency ratio be? 2.5x, 3x or 4x? It muliplies the HTT by this ratio, unsure how this works.

Looks like my next upgrade will be a new SATA HD (as quiet as possible!) and a graphics card. Not coming anytime soon though.

    The inside of my computer is messy.., but who cares as long as its stable. :rolleyes:

    HTT = HyperTransport technology. On socket 754, I think it runs double-pumped to the FSB - so around 400MHz. I am, however, not sure. 400MHz is probably a safe value to put it at or close to, but it also might be quad-pumped, which would be 800MHz. Anyone got more insight?

    my hTT is running at 800Mhz default...

    good choice on the heatsink. IF i wasnt using a Zalman reserator id use that

    so quad-pumped then. Set the multiplier aiming for around 800MHz.

    Nice rig Nive11en, and nice overclock :rockon:

    Thank You guys, I'll be going for a 3x HTT multiplier then.
    I wish my ram could clock higher though. Seems these Athlons are nice overclockers then? From 1800MHz to 2500MHz with not much problems. This weekend I'll try decreasing the voltage though and see how the stability is, might go down to 2450MHz just to feel safer, or have the feeling that my CPU is gonna live those few days longer due to smaller clock :p

    kk guys, since we have read all of our manuals like good boys, and review sites all round the world, HTT is the competing gimmick against Hyperthreading. Our mobos say that HyperTransport can flow from 1 gigahert to 2 gigaherts, at least on the ABitkv8 pro i own.
    timing wise, the adjustable multiplier is a factor of the fsb
    so using the default 5x on my mobo yields 200x5=1000 mhz speed used mostly for northbride to southbridge communication.

    thanks for telling to reduce ram mhz, and then oc further, im sure i can get up on some clocks with dual intake and exhaust fans

    can you tell me your voltages 911?

    heh well, i did up a bit of my own ocing, heres the setup on all air cooling

    CPU - A64 2800+ 1.8 GHz @ 2.35GHz (PR @ 3500+)
    RAM - PC 3200 @ 333/200 x 260 = 433MHz 3-3-3-8 timings
    HT - 260 x 4 = 1040MHz
    FSB - 260/200MHz

    CPU 1.7/1.5 volts
    NB 1.65/1.55 volts (max)
    SB 2.65/2.5 vlots (max)
    stock volt RAM, AGP, HT

    vid core 345/275
    vid RAM 297/270

    Sandra RAM 3267/3266
    Sandra CPU Arithmetic 10641/3830/4877
    Sandra CPU Multimedia 22253/24006

    3DMark2K - 20K
    3DMark2K1SE - 17K
    3DMark2K3 - 4.7K
    Source Stress - 87fps
    1M superpi - 39 sec

    Nive11en I have almost the same setup with you.

    A64 2800 @ 2511 1.475x113% with Thermalright XP120 + Titan Alu Fan
    DFI LP UT nf3 with Zalman NB 47J and mosfet heatsinks everywhere
    Corsair PC3500 (bh5) 250MHZ 2-2-2-6 3.2v

    The Cpu doesn't get over 284 HTT nomather what, even with the multi at 8x.
    What version is your A64?
    Can you please post an cbid screenshot?
    Here is mine
