    changing those mentioned settings doesnt even post ;p (i changed them through the bios) also made an awkward hardware related noise, i think ill stop while i'm ahead before i fry my ram.

    other than those suggested options stability is the best as its going to get (ram wise)? unless i blow 500fsb which i dont really want to do since my temps are already 67c after prime 95.

    Lowering your tRD would affect performance the most, 10 is pretty high too I would try 9 for sure.

    I would also lower your MCH Core voltage (Try 1.20-1.24), 1.36 is way too much, also set Performance Enhance to Standard

    for some reason when i set it to 9 in the bios (each channel) it wont post even while running it standard, so i just went back to the working setup, probably my rams clocking capability is awful..

    well update, its been stable at those settings posted on the first page since i put them in, i think ill walk away with my cookies now..

    thanks for trying to get the memory straightened out, but it seems that my memory isnt good enough to even alter a single thing on. as for the mch core, ill probably drop it back down to the normal voltage.. 1.20 from my last e8400 4ghz should be okay even though the fsb speed is higher right?

    For mch Core 1.20 and 1.24 didnt pass half a second of prime 95 large ;p 1.26 worked but i went to 1.28. ty for the heads up lol. was it even bad for the mobo that it was running at 1.36?

    Yes I spam posts with this.
    trd 9 at 490(1960 fsb) was fairly easy , it took a bit opf tweaking to get it at 2000 fsb.

    1880-1900 fsb which is what you are using with a 8.5 multiplier for 4 ghz.you should be able to get away with a much lower mchv.what that is you will have to determne for yourself.Probably 1.28 or less.
    do use a memory bandwith test programme and expect 10gb/s read and 10-11 gb/s copy/write as a maximum.

    Something like 480-490 cpu ref with multiplier at 8.5 ,mch v below 1.4, cpu v at around 1.4-1.43v and memory at 2.2v or below on a 2:00D multiplier should give reasonable performance

    2:00D.. erm i'm using 333mhz mch ref in the bios.. am i an idiot for not using 400mhz 2:00D? and thanks for that post kick, now i have a very very good guide on how to get 500 fsb, :]. (and my ram will notttt run higher than like 1080) so 2:40D is out of the question :/

    These settings were stable enough for my Q9550 to pass 24 h of Prime95 small FFT's, 24 h of large FFT's and 20 passes of Linx with max memory.

    thats a nice oc, and yeah.. those temps are like whoa.. lol.. but theres no way im going past 1.4v :/ especially for such a little ram speed boost, like 20mhz lol :/ (cause thats all i want now, i got 4ghz stable sadly at 1.32 mch core i believe.. or 1.34) any other less voltages fails and freezes the computer sometimes.. that cant happen because its my server. the specs that i posted on the first page minus like .010-.020 mch core is the specs im running.

    You need to adjust your MCH ref then if you find you have to use too much MCH voltage, that or you need to move to "D" multi's

    the mch ref is already calibrated for what i had originally 1.36, now im running 1.34 with the same mch ref so far so good, lsdmeasap could you tell me whats the difference between the "B" multis and the "D" multis? (if anything)
