Hypertransport Ratio Settings

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

Will be getting an nforce 939.

I'm hip to locking the pci/agp, setting the memory slower and bringing the
bus speed up.

But what's the hypertransport ratio?

    It multiplies the HTT buss speed by that amount. ie: 200 x 5 = 1000 htt
    ie: 250 x 4 =1000 htt.
    if you overclock you will need to lower the mul to keep the htt below or close
    to 1000

    Setting the memory slower;;;I thought that if you have for example an athlon
    64 3800+,2,4Ghz(12X200)
    and pc4300 memory(266x2=533)you can set:9x266=2,4ghz and set the HT
    multiplier to 4x(4x266=1066,close to 5x200=1000).

    It's pc2700 Corsair Value Select. I know I can get it to 175.

    cpu will be a 1.8 Ghz.

    Plan:

    270 x 4 = 1080
    or
    270 x 3 = 810
    memory at 133 = 174
    1.8 cpu = 2.43

    Yes you could, and HT speed really doesn't effect performance, even HT @
    3x here should be fine.

    Thats the CPU multiplier,not the HTT multiplier.

    The only problem I see is how the memory bus reacts to the system bus of
    270. Are you sure you can keep it down to 174? And I don't see how you
    came up with 174 for the memory bus either. Assuming it overclocks with
    the system bus and raising it by 70 would put the memory bus at 203. If it
    holds it's base speed at 233 system bus then the memory bus would be 170.
    And I doubt there's a chance in hell it will hold it's base speed at 266,
    but I don't know. When I set the system bus to 233, the ram bus increases
    from base by 33, but I have an older board. Hope yours will do it, but I
    sure wouldn't count on it. I don't recall if I even have a 100MHz setting
    for the ram, but that would get you going for sure. Good luck, but I think
    you'll have to replace the ram to get where you want to go.

    That's why he's using the 133MHz ratio. With a multiplier of 9, the 133MHz
    (2:3) ratio has a memory divider of ceiling(9 / (2/3)) = 14, which gives
    (for a system clock of 270MHz) the RAM speed 270 * 9 / 14 = 173.6MHz.
