    If you pace yourself just right, we will still be here after killing our gulftowns with too much voltage .

    Cooling was changed from MUGEN∞2(SCMG-2000) to Megahalems.  It and grease changed from AS-05 to Thermal Elixer.

    206×21=4322MHz Vcore 1.2250V(BIOS)

    but seriously thats a great OC,good job
    Yeah, I'd like to have these temps 24/7, but just 4,2GHz are that hot at load with 23°C ambient in my living room.

    This is not too hot, but also is great for 24/7 use, unless you are using some kind of "exotic"-cooling on this run. What kind of cooling are you using?
    My kind of exotic cooling (Not mine, just picked up at google!!!):
    Wintergarten Haus1.jpg

    Putting the pc in there, open all windows and doors, hope for good temps outside - it had 11°C then - and let the machine run!

    I have a good friend from america who didn't know my radiator, maybe you also don't know - so here it is:

    I have 9 x 120's on it!

    At 4.5, got 11+ hrs prime and linx max mem, but with indigo tim and 23C ambients and 2rads to keep load temps in mid 70's. If load gets in high 80s = bsod.

    At 4.6, I can get prime only few hours, and linx 20 run max mem, but with 15C ambients (outside temps). Inside temps = bsod.
    My aim was to run the computer as fast as it can do...due to the fact, that the pcie-clock is limited by Gigabyte at 103.5 MHz I can't go further. There's a Solder mod, but I don't have the heart to do that. Except this fact, the board is impressive and easy to handle to! I now know, that it is possible to run 4,6 GHz, but I don't need it!

    It takes a really good CPU-batch (+ good MB, RAM and cooling too) to get it Prime-stable at @4.6GHZ+.
    It is the ultimate 24/7 OC on the current platform, I guess.
    I know people running 4,8 on Chiller and one who ran 5GHz primestable with LN2!!!

    @emertX: You got a really nice cpu there, low voltage but also quite hot. If you you do the PCIe mod on your GB, I think you'll find that its easier to get 4.6+ stable with slightly less vcore at 104+ on the pci. Thats my experience atleast.

    Yes, max bootable/stable bclk now is 232 (228 before mod). Think i need cold to get further.

    Could you explain and tell with which voltages you got 4,7GHz primestable? Edit:
    Just saw, you just took 4 Threads...Mine is with 8 Threads.

    @5GHZ Primestable is great, but LN2 won't work for 24/7 you know.

    That 9x120 looks good. Sniper got the same batch# as you, and I remember he was talking about low-voltages but extra heat on this batch#.
    I see 9x120 got the heat under control on that hot CPU, good job . With this kind of "exotic"-cooling, you should go for @4.7GHZ now, ... go go ..

    The mod is probably easy if your good at soldering, think hicoockie said he used 1 min to do it. For me it was not that easy, but got it in the end.

    In normal room temp (22-24 degrees) with 2 360 rads with 1200/1400 rpm fans my W3520 can do ~3640 HT on and ~3750 without HT and still be under 80 degrees in RealTemp for Linx/Prime.

    24/7 I'm running at 4515 1.328vcore 1.3vtt and fans turned down to ~700 rpm.

    Seems to be the same as mine, but I'm using 1,34Vtt and 1,29V Vcore @ 4,5

    Do you still have the board?
    Could you take a photo from the solder?

    Do you Giga owners find your board undervolts much?
    1.2 in bios gives me 1.152 in CPU-Z.

    @vaio: Yes, that is typicall for GB.

    Oh man...if I will gain that much with the mod??? My board is primestable @ 19x226 with 8 threads, so it is very good, and I do not want to damage it due to some points in 3dmark...

    Up to page 66 of this epic novel

    Seemingly solid at.

    200 x 19 HT on.....1.212v in bios (1.168 in Windows).
    Makes for a decent lil cruncher.

    In sig

    Running nice and conservative 3.8 at the moment.

    200 x 19 HT on/Turbo off.
    1.212v bios.....1.168 in Windows......temp max 70c under crunchy load-in a closed room with no window.



    Acts up at anything over 3.8 so leaving her be for now.
    Voltages need tweaking a little to go higher (if she can) but right now she seems rock solid so leaving her be.
