P4 800 FSB: 3Ghz >3,6 Ghz

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

Using only the multiplication factor, my P4 system 3.0 Ghz - 800 Mhz
FSB now runs at 3.6 Ghz on an Asus P4P800-E Deluxe - EAY - 865PE.
The voltage was upped to 1.55 V to compensate mild power drainage.
The RAM (400 Mhz) was downed to compensate the multiplication factor
and thus clocks at 400 Mhz again...
There's & Coolmaster Gear ventilator on the processor,.. a ventilator
on the chipset and a ventilator pulling fresh air in from the
front,... processor temperature stays below 50 celcius and chipset
temp below 45 degrees during XP stability test.

Any comments?

    Hi,
    what do you mean by "the multiplication factor"

    Nice overclock :)

    I assume by "multiplication factor", you mean you altered only the CPU
    multipler?! But this can't be, since all P4 800's are multipler locked!
    The only way to OC to 3.6GHz is to increase the FSB. So, like the others,
    I'm confused.

    Huh? There's no relatioship between the CPU multipler and memory. The CPU
    FSB * the multipler determine the CPU "speed". In your case, that P4 3.0GHz
    is 200MHz FSB * 15 (stock). To run it 3.6GHz (OC), you'd need to change the
    FSB to 240MHz (240 * 15 = 3600 = 3.6GHz), and perhaps more vCore (1.55v?).
    If the memory is PC3200 (400MHz DDR), and is not overclockable (not likely
    to 240MHz!), then you should be running w/ a 5:4 CPU/DRAM ratio (240 / 5 * 4
    = 192MHz), or in Asus terms, DIMM Freq = Auto), which is perhaps what you
    mean by "downed to compensate..."?! Yes, your memory would be underclocked
    under this situation.

    Beyond that, I'm not sure what comments you are seeking.

    I'm not an expert in overclocking,.. but want to find out if my pc
    builder did a good job.
    Is "multiplication factor" a wrong traduction into english? With that
    i suppose it must be "multiplier"

    This is what's confusing them. When you say "Using only the multiplication
    factor" it implies to them that the 15/1 (the "multiplier") was changed to
    something else; but it wasn't and, as people have noted, can't be changed
    on P4s.

    This is where the overclock was done: increasing the FSB clock from the
    standard 200MHz to 240MHz. I.E. Using the non changeable 15x CPU multiplier
    shown above, it was originally 15x200 for 3,000 MHz and is now 15x240 for
    3,600 MHz.


    > CHIPSET1:
    > Speed: 2 x 192 MHz (348 MHz date rate)

    This is your memory clock from the ratio below. 4/5 of 240=192

    Technically this is not being used to 'overclock'. It's being used to keep
    the memory at a speed that will work with the CPU overclock and is actually
    under clocking the memory by a small amount [((192/200)-1)*100 = -4%].

    Thank you for your expertise. You've helped me understanding a bit
    more how the overclocking was done. anyway.. the system runs smooth a
    teperature still is below 40° celsius. Seems a good job done...

    Well, if the memory could handle 480MHz that would be better but odds are
    it can't, which is why the 4/5 ratio is there.

    I have now the same setup mobo+cpu.
    Running at 3780 on a daily basis for stability purposes, but at 3900
    for benches and testing...
    Temps goes from 27 idle to 36 at 100% for 24/7 @3780 ( on WC ).

    I have the same problem that you do with memories.
    My GEIL ULTRA PC3500 can't do 1:1 at 260, but allows me to run at 5:4
    with 2-2-2-5 timmings.
    Trying to find the best place to get some GEIL GOLD PC4000 for 1:1.
    Nice rig you got there...
