    Default GA-EP45-UD3R voltage advice with q6600

    So I have this gigabyte board and a q6600, with a box listed core of 1.35v. I can run solid at 3.2ghz at 1.3125 in bios and most everything else auto except for ram which I have at 2.1volts. I'm trying to get 3.6ghz, and can get into windows and run prime but it gives a BSOD and memory dump after a few minutes into it.

    In bios for 3.6ghz I have it set at...
    1.475 vcore
    1.590 cpu pll
    1.300 mch core
    2.100 vdimm

    Rest of the voltages are auto. At this point I've been trying to read from various different websites and forums the more "typical" tweaks people needed to get things running right as I have been out of the overclocking world for some time. Any help would be greatly appreciated.

    thanks,

    Tellerve

    Please post your full specs, and a link to your ram. And please also check in CPU-z And see what voltage setting 1.475 in the BIOS is actually giving you in windows.

    Without your specs I cannot advise much more, but after you give me them I can give you a full set of optimal ranges for 3.4-3.6. BTW, what cooler are you using?

    Newegg.com - Patriot Viper 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

    That's my ram, I have a q6600 g0 stepping batch L814B720 that has listed on the sticker on the box Core 1.35V. I have two of these in RAID 0; Newegg.com - Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - Internal Hard Drives

    An Arctic Cooling Freezer Pro 7 on the cpu, and a Asus EAH3450 graphics card, and a samsung dvdrw, and a Antec Truepower 430w power supply that I've had for a bit but haven't actually used in awhile. It was a warranty replacement for an older one and has barely been used.

    I have this bracket showing up tomorrow. I was going to get the 1283 heatsink from them but my order got messed up somehow and so I'm thinking I might just use this with the Artic Cooling FP7. Also looking into lapping them both tomorrow.
    Newegg.com - XIGMATEK ACK-I7751 Retention Bracket - CPU Fans & Heatsinks

    I'll check to see what it shows up in cpu-z in just a bit an edit this post with the info.

    thanks,

    Tellerve

    EDIT:

    In Bios for 3.6ghz (400x9)
    pci express is 100mhz
    dram is turbo for performance enhance
    gmch is auto
    spd is 2.00b =800mhz ram
    Vcore is 1.475
    pll is 1.59
    mch is 1.26
    vdimm is 2.1

    Inside windows cpu-z reads 1.456v, and I recall it going to 1.44 at times when it was running Prime. BTW, these settings caused a BSOD and memory dump in windows vista 64bit after a few minutes. Temps were unlikely a factor as it is f'n freezing in my apartment as the heater is out and I live in NYC, but maybe they had something to do with it. IDLE at 31-31-28-28 or thereabouts.

    Yeah, the ram is that shiny and green. It is pretty ram for sure, not sure how great it is, but it was cheap and at least supposedly good :).

    That looks like some nice ram, is the heatsinks that shiny/colorful in reality?


    OK, you may or may not need some CPU Voltage, but without seeing all your other settings I cant say for sure. But I can tell you a few you listed will cause issues.

    So........

    This is what I would suggest as optimal ranges for your setup at 3.6 >>>>

    Ok, so

    401mhz x9 at
    100mhz pci express
    standard dram at 2.00D for 802mhz at 4,4,4,12
    advanced ram timings at 4,6,6,52,5,2
    channel settings at 9 and 800mhz
    voltage settings for cpu in bios
    1.48125v core
    1.3v cpu termination
    1.59v cpu pll
    0.848v cpu reference
    MCH
    1.26v mch core
    1.57v ICH i/o
    1.2v ICH core
    DRAM
    2.1v

    Any other voltages were set to auto. Also turned off the sleep states and such of the chip like you mentioned. Hopefully I'll be able to get those back on though as I enjoyed having my computer be able to do that. We'll see. Off to test it, and hopefully not loose my raid array again.

    edit: BSOD in Prime in a few minutes. :(

    Really? Less voltage? Huh, ok, well I'll try it. Hopefully this weekend I'm going to get some sandpaper and lap both the HS and cpu as I just got the crossbar bracket and want to get that done before I use it.

    Tellerve

    EDIT: Sigh, BSOD in Prime after a few minutes, maybe a bit longer, but still not very long. I should also mention that sometimes when I change bios settings that when it saves and reboots it sometimes cycles the boot. It beeps tries to get started and then stops. If I unplug the power for a 5 count or so and replug it in it can boot up again and works fine. I had figured this might be not enough voltage at 3.6, but after being at 3.6 and going back to 3.2 it will happened as well. Strange.

    Yes, Less is better. And with P45 less can often be needed when more would be the obvious answer, especially with Vtt as it affects other settings, and MCH less can be needed sometimes too when you would think more would help depending on the strap and multi used

    A double reboot is normal when changing certain things in the BIOS, triple always means incorrect settings were uses.

    If you still have issues please post your full settings again that you are now using and I will advise

    Well starting the computer, going into BIOS and switching to my saved 3.6ghz bios loadout and changing the voltages to the following, otherwise the same as above:

    1.4875 cpu vcore
    1.260 cpu termination
    1.5 cpu pll
    0.823 cpu reference
    1.22 mch core
    1.57 ich i/0
    1.2 ich core
    2.1 dram voltage

    It tried to restart and did 5 boot start/power ups before I unplugged the power and waited a bit before plugging it back in. After doing that and hitting power it did one boot loop before starting up into windows. I'll now throw some Prime, or if I really want to see a BSOD Intel Burntest. Will report on how quickly it came in an edit.

    EDIT: LOL, BSOD page fault in non-paged area in less than a minute with Intel Burntest
