    i don't think anybody will know for sure until the overclocking starts on each CPU.
    i myself would pick the newest batch available.

    however, if you can spend more for an E8400, then try getting an E0 stepping of this CPU.
    it's almost guaranteed that you will get a very decent overclocking with low vcore voltage.

    when the CPU FSB is increased from the default 333MHz to 400MHz the board's BIOS is usually smart enough to up the vcore for you.
    however, the CPU may not require such a high vcore voltage to run at that clock speed, if you want to, you can try manually setting the vcore voltage (that best suite your and CPU needs)

    1st attempt at high FSB overclocking.

    E8400 @ 580 FSB (boot direct from BIOS into Vista).

    [​IMG]

    BIOS...
    vcore 1.20v
    PLL 1.54v
    CPU GTLref 65%
    vtt 1.24v
    nb 1.34v
    NB GTLref 60%
    sb 1.20v
    CPU clock skew Delayed 200PS.



    it seems like without RAID and dual graphic cards setups the max FSB within Windows could be 600 MHz or even a little higher.
    the room temps was too high to continue overclocking anyway.

    @ 585 FSB

    the board's FSB seems to max out for now at 590 MHz, this could be due to too many hardware devices attached to it.
    i believe the CPU itself still having some FSB left to overclock more.

    [hobo]eclipse,

    just for your info. the particular 2x2GB PC2-8500 PK you're having with you, is a quite good overclocker RAM kit,
    i already tried overclocking a PC2-8500 PI which is i assume it use same memory module parts with your RAM,
    the one that i tried won't get pass 1080MHz and still stable, and nothing at all will help by increasing voltages.

    i don't know, mine are rated at 2.1V default for 1066. these respond well at +0.25v to get them at 2.05v +\-. i've never gave them a try undervolting them but arent the PI's rated at 1.9v?

    nope the PC2-8500 PI one has same voltage spec as yours, DDR2-1066 2.0-2.1v,
    when i tested it i use 1.96-2.0v for 1066-1080MHz and it wouldn't overclock more than 1100MHz or so. but it would only stable as much as 1080 MHz.
    tried vdimm upto 2.3v wouldn't help. this may have some to do with motherboard, as well as the particular RAM modules itself.


    on my post above #135, that one was using the PC2-8500 PI serie RAM kit,
    since this particular RAM kit wouldn't overclock well i didn't want to buy another kit at the time,
    i thought it could be even more worse if i would run this memory 4x 2GB.

    Wow this is a very very good Quad-Core overclocking achievement without using an extreme cooling system.

    if i'm not mistaken, this's on air, with Gigabyte EP45-DQ6 (which seems to be a very good motherboard indeed) and Thermalright's IFX14 cooler.

    [​IMG]


    he was also get in to a 4.6GHz with below 1.38v vcore.
    an amazing overclock on this Q9650 chip, and a very good CPU's temp too.

    523 FSB (and x9 CPU multi too) with this Quad, this's like 650 FSB on a Dual CPU, no?
    i think, besides he is very lucky to have owned such a good motherboard and a really golden Q9650 CPU,
    the guy knows what he is doing with his hardware and his overclocking so well. i really admire his achievement.


    =======================


    Wow he just went to 534x9...


    [​IMG]


    this's really positively impressed me on how good his motherboard is.

    he didn’t want to stop, lol. both his motherboard and CPU are very impressive.

    545x9

    it's indeed an overclocking with Air cooling.



    it's funny to me that how come some of the members over at XS forums did not believe the guy really achieved all of the overclocks the he was sharing to them on the thread.

    i guess it's supposed to piss those people off quite a bit if they keep getting different achievements during overclocking the same Q9650 chip.
    personally, i have no doubt that all the overclocks that belongs to NapalmV5 were real from the beginning i found them.

    well i just think the Q9650 is one of the Intel's newest Quad and these overclock results are pretty unique and amazing.

    600Mhz - on air - Jeez... :w00t: Your temps are just outstanding!

    ...and your memory is holding you back??? Whoa...

    swimtech,
    actually, 625x6, 600x7.5 on air, but, it's for max screenshot only.
    i have another RAM kit on a system my kid is using at different living place. i believe, with the RAM kit i can do 650 FSB.

    I love that mobo Panging tho I'm not as crazy as you;) Sorry to bump an old thread but I'm extemely impressed by this board and cpu. I never dreamed of taking a quad that far on air

    sweet clocks dipstick, wicked 100$ boards these UD3* series are! I have the R rev 1.1 mobo. 90 buks around xmas.
    enywayz, long story short, i bout a month ago got "defective" X3360, wouldn't do a damn thing for me in the FSB area, n when i say nothing, i mean nothing, 350 FSB was a problem.
    tryed for a week straight, it was a C1 stepping with a 1.25 VID, pretty disappointing, was hoping for a E0 Xeon. Like i said it was a pooper n i got it RMA'd. Love the egg.

    So when the new chip arrived i was disappointed once again when i seen SLAWZ and 1.25 VID on the box spec,
    same C1 chip i thought, debated even opening the thing, but i did and was treated. upon first boot bios recognized the VID as 1.225v which is a great sign.
    so far things have been a lot better with this chip. Boots no sweat at 4.0 471 fsb, nb/RAM unstable for now but im oc'd out from my week of hair pulling with the pooper chip.

    went for a low volt OC, only voltage set in bios at first was RAM to 2.08 and ICH core at 1.2 and I/O at 1.57, did this because i am running 3*Seagate 320GB in a raid0.

    was able to get to 410*8.5, 2.66*410 RAM with all stock volts except ones mentioned above.

    now at 420*8.5, 2.66*420 RAM, all that was needed was to bump the vcore to 1.25 and MCH to 1.16v

    at 425 my RAM is getting up there and im not sure yet what is unstable, haven't fooked wit it enough but when i get the urge n find out i believe that will be a key for my big fsb stability aswell.
    like i said im oc'd out for now and summer is rolling in. plus will be fun to not oc to max in the first month or so, lol, o and these clocks perform something wicked in themselves!

    pack date on this thing is 04/02/2009, im takin that as feb 04, 2009 is that right? the one returned had a dec 31, 2008 date, but i cant recall the date format. i should have pic'd the box side.
    first two cores temp sensors seems to be stuk at 37 for idle, which is not uncommon for the C1 step, core 3-4 i believe reflect more of an accurate idle temp along with the main cpu temp sensor.
    they all come in line under load though which is a good thing for sure.

    good thing about this OC is i still am using all of the power saving features in the bios. with big OC (4.0) i was idling consuming 20A and 30W to the CPU according to everest.
    with 90-100A and 150-170W under big linpack load, temps also become a problem for me up there, as im running a noctua fan that maxes out at 1300rpm,
    i need a 4pin intel spec PWM fan that goes up to about 2500 RPM

    That's an astounding difference on those processors hobo - and the voltage you got for that 3.57Ghz clock - killer!

    Sweet sample there dipstick - it's gotta feel really good to get so far over 4Ghz with a $100 board!

    You guys have tweaked me to get off my keester and see what this Q9400 I have loligagging along at 3.4Ghz at 1.25v (bios) will do. She came with a 1.2v VID too...

    Maybe even Panging will take a look here. Wonder what he's got going lately...

    Edit: BTW [hobo]eclipse, I noticed Gigabyte has a new bios 6c available for our EX38-DS4 boards in the last couple days...
