    I know this memory is rated at CAS 5, but did you try CAS 4 ever? That's why Chikes scores are a lot higher.

    And since you are under 800Mhz anyway, you might be able to run 444-12, but try lower tRD first 6 or 7, then CAS 4. All of that may require more memory and or MCH voltage though, up to you on if you want better performance or not, and again the memory might not do it anyway but it's worth trying. If you do try CAS 4, set tRD 8 or so first, then try CAS 4, then lower tRD if CAS 4 works with high tRD

    No I ram with the same memory multi and timings, and also left tRD auto which set it yo 9, but still had a bit better memory performance, see post #129 and post #132 but that's expected P45 has better memory performance than P3xm X38 and X48.
    At 666 he may do CAS 4 but higher I am not sure, but better leave it 5 higher than this.

    He may be able to lower tRD to 7 I think.

    One of the main problems is that this board does not have MCH OverVoltage control.

    Ahh ya, I didn't even think of the chipset's being different, that will make a good amount of difference in performance or benchmarks.

    So, ya scratch all I mentioned above too, I forgot there's no MCH voltage control!

    Hey guys, I'm back lol....yeah, tRD is already at 7. The latest BIOS setting screenshots are on the previous page along w/the latest Intel Burn Test and Maxxmem/Realtemp numbers. It's too bad I can't max my RAM out at 800mhz because of this board (yet). 710mhz is the highest I've been able to get it based on FSB of 355.

    I tried raising the cpu voltage to 1.356v (vs 1.34375v used so far) to up FSB to 366 last night with auto PCI but it crashed and loaded default settings. Tried it with 100 and then 101 PCI but still crashed so no 366FSB yet even w/1.356v. Should I try any higher voltage before hitting the 1.36v barrier or look at other settings?

    Perhaps loosen timings just a bit to help with an FSB of 366 or higher?

    UPDATE: Leaving everything else alone, I'm trying an FSB of 377mhz w/cpu voltage of 1.34375v. It's booted up stable this way w/PCI set to 101 but fails Intel Burn Test after 2 passes so far...

    Hey check out this link...it says the RAM has an EPP mode that will auto configure timings for OC'ing ram.
    http://www.ocztechnology.com/ocz-ddr...l-channel.html
    And this next link shows they OC'd the ram to 1100mhz. Am I being too conservative w/ram timings? Should I set Timings mode to 'Auto' in BIOS perhaps?

    The PCI is not the problem, try 360.
    Rumor is E7200s don't like a too high voltage, but while your idle voltage is up to 1.3625v you should be OK.
    Mine need very little,compared to the E7500 that needed 1.425v or so in BIOS to run 1.825GHz this one needs only 1.35v, (1.312v under load) for 3.85GHz.

    Quit showing off your manly E7200 scores Chike!! Just kidding haha....When testing the 377FSB gflops hit 23.xx for 2 runs before crashing which was encouraging but I'll back FSB down and will try 360 though I'll be in and out today.
    Should I loosen memory timings the higher I push the FSB? Should I keep voltage around 1.34v for now? I don't want to push voltage to the limit just for an extra ghz so if it's better to stay a certain margin under 1.36v, that's fine...

    UPDATE: 360mhz FSB only booted and passed IBT with PCI Frequency set to [Auto] in BIOS. Will not POST with PCI set from 101-103.

    There will be no more this is my final OC

    377 or 366?

    The memory is still under it's rated frequency it should be fine like that, set tRD to 8, just to make sure it's not in the way, later you can try lowering it again.
    What is the voltage level under load now?

    What's the score?

    377 with PCI set to auto...366 wouldn't work so I tried bypassing it. Forgot to capture scores on that one since it failed...

    I'll have to double check, I've been playing w/different voltage, spd and fsb settings to find a happy medium. I'll report back soon...


    What's the score?
    I think this is the correct one, I did alot of captures last night...

    Everyone makes it's own limits, but i ran IBT with even over 85c.
    Up to you, but IMO 75c is quite safe.
    BTW were are you located? I mean on this planet.... if you are from this planet.

    Here's the latest 360FSB run: Running PCI on auto (101-103 crashes), 2:00/1:1 spd, tRD=8, cpu voltage in bios=1.35v, 1.31v at idle (CPU-Z)
