    How is this overclock?

    CPU: e6600
    MoBo: Abit IP35
    RAM: Geil Ultra low latency (4-4-4-12 PC6400)
    GFX: 8600GT (don't game much)
    CPU cooler: Tuniq tower
    Case: P182

    FSB: 1480
    CPU: 370*9 = 3330MHz
    RAM: 4-4-4-12 @370MHz
    ambient temp: 26
    idle temps: core 0: 25 1: 28
    orthos temps: coe 0: 45 1: 45
    system temp: 38
    orthos stable 6 hours

    I'm not sure how much more I can safely push it. I felt comfortable up to this point so thought I'd seek some advice before going further. My cores are at different temps at idle but the same under pretty much any load, is this ok as I reseated the heatsink once to get from 47 under load to 45 and it's a motherboard out jobby to reseat it and I'd really prefer not to do that.

    Re: How is this overclock?

    Orthos stable at 380*9 for 15 mins so far, touching on 49C though so that might be my limit without putting my fans on higher than medium!

    Edit: Shame I can't undervolt on this motherboard though!

    Re: How is this overclock?

    The important part is how much voltage your putting through you cpu and north-bridge and that board will go higher than 380, my quad gt could do 425x8 with my E6400.

    Stock on the CPU, all bridges and RAM.

    What I'm worried about is the lopsided idle temp and the 48C peak temp.

    Re: How is this overclock?

    Temps looks OK for me considering that Tuniq doesn't have the best finish of the base by default. You may consider lapping the thing, but do make sure to keep the base flat. Mounting of such big heatsink may not always result in proper contact on all CPU surface. Also thermal grease type can influence the temps and changing to something like Arctic Silver can drop couple degrees. I personally use Liquid Metal Pro compound, but that thing conducts electricity and should be applied/used with extreme caution not to burn the hole thing down But still it's the best heat conductor

    Re: How is this overclock?

    That's stock vCore, not auto? If so you have probably acheived the greatest overclock of all time Get over to xtremesystems and let them know

    Manually set to the minimum the board will allow on vcore.

    cpu-z reads 1.264v.

    I have no idea how to lap a heatsink. Could it be possible I've mounted it wrong? I use AS5.

    Edit: It's not orthos stable at 380 (BSOD), but is at 370. I think I'll leave it there as it's fast enough for me and the temps are ok.

    For reference hot hot is it safe to run these?

    Re: How is this overclock?

    Those temps look ok to me on full load...in this weather my e6600 at 3.6ghz with a Ultra 120 touches 54C on full load and its just fine

    Re: How is this overclock?

    Just google for heatsink lapping - there are plenty of reviews. Just prepare small piece of glass (without sharp edges) and smal grit sandpaper and lots of patients

    To check the mount you have to remove the heatsink and see the thermal grease on the CPU - does it have any thick layer places (sorry for my english ). Also c2d processors are famous for being concaved and badly sometimes so it's impossible to get really good contact unless you'd lapp the processor (voids warranty !).

    Re: How is this overclock?

    OK, I think I'll avoid lapping but I have a few questions:

    Is it better for the heatsink fan to blow towards the back or the top of the case (I have a 120mm fan at the back and another at the top?

    Speedfan warns me when the CPU hits 50C, should I stop at 50C?

    How tight should I turn the screws on the heatsink?

    Cheers guys.

    Screw the heatsink till it will be very hard to turn the thumbscrews by hand. Do it cris-cross (or how that should be spelled) in several attempts. Check installation flash video of Zalman VF-900 on their website. It's good reference.
    Maximal operating temperature for this CPU is 60C.

    Re: How is this overclock?

    Redone the thermal paste using the line method. There's still a 3 degree difference between the cores at idle but is this a problem when under heavy load they are the same?

    Edit: Both cores are 43C under orthos blend two threads full load.

    Edit 2:

    It doesn't seem that special. 3330MHz seems to be well below the 3.6GHz a lot of people get :s

    Re: How is this overclock?

    Upped the voltage up 1 notch and it appears to be orthos stable (only 2 hours though) at 380MHz.

    Peak temp is 47C but it is a bit cooler in my room now (24C rather than 25C).

    Fantastic little chips these C2D's, very glad I didn't got for the E6750 or Q6600 (out of budget anyway) now

    Most people need a good healthy voltage increase for 3.6, yours is a very good OC with no vCore bump

    Well I've had to bump it up 1 notch to get 3.42GHz orthos stable

    I deserve this luck after having pitiful AMD 63 3500+ and AMD X2 3800+ with pitiful overclocks
