    Default GA-EP45DS3P and E8600 settings tips?

    Ok guys my first post here scarry lol
    Serious hoping for some help or advice how to clock this beast stable with my system at 4 Ghz...

    System spec...

    E8600
    GA-EP45DS3P (F7)
    Corsair CMPSU-620HX 620Watt, ATX/EPS12V
    E8800GT 512 MB MSI
    4 x 1 gb OCZ2P800R22GK
    Scythe "Infinity/Mugen" 5Heat Pipes CPU Cooler
    Temps Idle 38/35 (Mobo/CPU) Full load Core 56/56 )OCCT 1 (hour stable)
    Vista 32 bit SP1

    Ok stable at 3950 Mhz but had a blue screen stop at 4000 Mhz
    Have a large experience with hardware and software but a newbie with overclocking have done some modest clocking with the GA-P35DS3 and a E6850 which my son now has only without the OCZ memory which I have now :-)
    Timing on the P35 where 4-4-4-12

    OK hoping for some tips to run stable at 4 Ghz

    Bios settings below thanks for the help in advance...

    you'll need to put the vcore up to 1.3-1.45V (start at about 1.4 and then if you can boot you can lower it to reduce heat)... Push up the MCH voltage to between 1.2-1.4V and manually set the DRAM voltage to at least 1.9V (i believe thats the rated voltage, but it'll be on the sticker)... put the MCH strap at 333MHz for 400MHz FSB (should give you better stability). I'd probably put the timings as follows:
    Advanced Timing Control
    tRRD............................................:4 or 5
    tWTR.......................................... :8-10
    tWR.............................................:6
    tRFC............................................:b etween 50 and 60

    tRTP...........................................:Au to
    Command Rate (CMD) ....................:2

    also set the static tRead up to somewhere between 7 and 11.

    That should give you a bit more stability. If you can get it stable with those settings, you might even be able to run that memory at higher frequency, so you an probably up the multiplier to 2.4 for 960MHz.

    Do you get the BSOD at 400MHz when you start doing a burn test or something or is it just straight after you boot into Windows? Can you check your temps at 395 and post the average core and chipset temps?

    Ahh nothing to be scared of! So you can get 3.9 fine almost but not 4Ghz right?

    I see you have speedstep on that is likely why you have issues. When you PC is idle with that on, the CPU multiplier gets downclocked as well as the Voltage which was likely causing you issues. Should be off for sure when you overclock, and especially with that much of a overclock.

    Try this >>>

This for sure needs to be manually set for 2 reasons, auto may give to much or not enough, and without it set you could not be getting enough, or you could be frying the ram. If it is 1.9-2.1 (2.2 EVP) then set to 2.1 and then later you can see if 2.0 will work. 1.9 likely will not with 4GB To use 4-4-4-15 you will for sure have to set 2.1 or 2.2V

    Thanks much appreciated going to do a test.
    Was indeed testing with 400 x 10 at vcore 1.25000V and memory at 2.10000V (memory advise is between 1.8 and 2.1)
    FSB was set at 960 indeed via the auto function and timings 5-7-7-18...
    Boot went fine into the system but after 15 mins (OCCT) I got the blue stopp... temps core where around 59 full load...

    OCCT show the VCORE use during the test and it never go beyound the 1.20000v

    45nm chip has a max of 1.365V Vcore I believe...

    Memory worked fine on the P35 mobo :-) with timings 4-4-4-12 and FSB of 400 x9 for the E6850 stable :-)

    During the last test a ripple of 10%

    try dropping the vcore just a little bit (like 1.23 or 1.24V), if it boots, it should reduce the heat and electrical resistance within the CPU (which sounds like the problem, i think the hottest i ever saw my CPU when doing burn-ins at 3.85GHz was about 60-62 before it crashed). you'll wanna try and find the lowest core voltage you can boot and run stable with. btw, OCCT shows your vcore as no more than 1.2V because of the extra resistance caused by a hot CPU, which is refered to as CPU droop

    if you're running your memory at its rated frequency, you can probably leave the memory a bit lower, just to reduce the heat generated. did you up the MCH a little bit?

    Yeah that Vcore max is correct but what you set in the BIOS is not what you get in windows, about .1 less. Check your Vdroop with CPU-z and you will see the difference

    Well I see you may need 2.2 or at least it is warrantied for your ram, but yeah 2.1 is cooler and is likely all that is needed

    Use 402 or so, not 400 FSB exactly as it is right on the strap

    Ok guys thanks really appreciated but with manual ram settings the system won't boot so after 3 tries back to the default speed settings...

    However with Vcore 1.3 (to high I think) and all settings but ram on auto (960) in Vista see screenshots...















    Thanks again for all the help hope the screenshots are helpfull for you guys...
    Ok note adjusted memory and via cpuz now at 1.23V so going to test OCCT...

    Ok after 30 mins OCCT at 4.02Ghz the screen just freeze in Vista...

    New test at 3.99 Ghz 1 hour of OCCT system is stable ok going to test a bit more any ideas guys?

    Disable and uninstall EasyTune. Feel happy to get almost 4.0GHz with such a stuff onboard :) Now You must dig only in Bios; Set vcore at least to about 1.4V (1.45 would be better when You have reliable CPU cooling- just watch the temps) and go!

    Thanks guys found the problem during a Bios reset the b Channel advanced memory settings where changed and set for a strange reason reverted back to Auto settings.

    Memory now running at 4-4-4-15 and 2.0V (2.00D) :-)
    E8600 at 3.99 Ghz lol
    No lockups so going to do a bit more testing temp mobo/cpu 36/38 Idle full load core 56/56 actually going to decrease the vcore :-) running in bios now At 1.197500V stable... now a lot of tweaking to do appreciated all the responses :-)
    If you guys have any tips please be so kind to share them :-)
