Problem with Q6600 O/C

Alright ladies and gents, before I start to say anything I wanna state that I know how to O/C and the basics of whats needed to be done and such. Now my problem is that when trying to overclock my Q6600 to 3.0Ghz either my second core always fails or the CPU runs way to hot to be stable. Whats even more annoying and weirder is that my CPU is G0 Stepping and apparently they are the best model of the Q6600 to O/C and dont over heat easily and take less power to supply CPU when o/cing.

Now my specs for my computer are:

CPU:Q6600 G0 Stepping
GPU: XFX 8800GT Alpha Dog Edition
MOBO: P5K-E Wifi-AP Edition
PS: OCZ 600W StealthXStream Power supply
HD: 500G Western Digital
Heatsink: Arctic Freezer Pro 7
OS: Windows XP SP2

Now here are my settings in the BIOS:

C1E Support- Disabled
Max CPU1D Value limit- Disabled
Vanderpool technology- Disabled
CPU TM function- Enabled
Execute Disable bit- Enabled
PECI- Enabled

Ratio CMOS Setting- x9
FSB Frequency- 333
PCIE Frequency- 100
DRAM Frequency- 667
DRAM Timing control- 4-4-4-15

CPU Spread Spectrum- Disabled
PCIE Spread Spectrum- Disabled

CPU Voltage- 1.3125V
CPU GTL Voltage Reference- .63x
DRAM Voltage- 2.00V
FSB Termination Voltage- 1.20V
North Bridge Voltage- 1.40V
North Bridge GTL Voltage Reference- .63x
South Bridge Voltage- 1.05V

Honestly any advise or legitimate geusses are welcomed at this point since ive fooled around with the voltages of the CPU, FSB term, NBV, and DRAMV but the results are either over heating or not enough power for core#2. Which also brings me say that I believe my second core is apparently a "bum" core. Not sure exactly what the is suppose to mean but I can see it isn't good since its the only core that always fails when running FTTs on Prime. At those settings right now my idle temps are 38-38-34-35. I honestly have no idea what else to say since ive been doing trail and error for the past couple of days from 3-4 hours a day...yet the results are always the same. I also should mention that usually when Core#2 errors up, it errors up either as soon as I run the test, 30s after I run the test, or a 1-2 minutes after running the test. So you see no solid results so far. Please help me :(. Thanks in advance.

  1. Really not one person can help me here or some helpful and useful advice at least?
  2. dude knowing from experience the arctic freezer 7 pro is crappy for overclocking the Q6600, step up to something better as the proc will heat up to fast, also, raising of voltage may be in order. When i had my freezer 7 on my Q6600 i only got 2.9ghz however when i stepped up to the thermalright 120 ultra extreme i managed to get 3.6ghz@1.43vlts
  3. oh, and ALWAYS keep ur memory and fsb linked preferably at 1:1 or it will severely limit ur oc, when mine was unlinked i could only get 3.25ghz@1.47vlts and as u can see after i linked them at 1:1 i got a higher clock at lower voltage
  4. THANK YOU! Finally man. Awesome will do change than. Ya I read that 1:1 ratio is the key to keeping the cpu alive longer and getting more out of it. Once agian, thanks again pal.
  5. anyday dude
  6. just make sure with ur mem linked that u don't overclock ur mem to the point that u think the cpu has crapped out, if thats the case raise the multi, or raise mem voltage, or lossed timings :)
  7. lossen*
  8. Ratio CMOS Setting- x9
    FSB Frequency- 333
    PCIE Frequency- 100
    DRAM Frequency- 667
    DRAM Timing control- 4-4-4-15

    Try dropping your multi to x8, FSB=1600 RAM=800
    That will give 1:1 (400x8= 3.2Ghz)
  9. Can you disable Core#2 in the BIOS and run Prime and see if you continue receiving errors?

    Specs from OCZ website
  11. Will try the x8 multiplier in a bit and see what happens than. Um I looked all over the place to see if I can disable the core but nothing. Will keep an eye out. Brb in a bit.
  12. its your memory or cpu voltage or both

    voltage should be 1.39-1.42 for 3-3.2 and 1.45-1.47 for 3.4-3.6 -- voltage is too low too

    first crank your ram down and increase the ram voltage 5-5-5 and 2v for 2g and 2.05v for 4gb

    then crank up your cpu

    you talk about being too hot and you have 30-34c - too hot is 80c????

    you say you know how to oc? but you do not change your voltage?

    i have seen q6600 that would not even boot hardly at defult voltage of 1.3-1.33 and you have to crank up the voltage just to get the cpu stable at stock speeds -- yet i never seen one q6600 that would not run 3.4ghz in intel chipset mobo with voltage set properly

    key to stablity is the correct voltage
  13. The problem is that when having the voltage at 1.335 my idle temps are 45-44-42-42 and full load go pass 72 than the computer just reboots itself...which im geussing is because the cpu got too hot. Ive fooled around with the NB, SB, RAMV, and cpuv like nuts but still cant find the perfect v for stability and cool temperatures at load. I tried 8x and 400FSB but when the Windowsxp loading screen just came up the computer rebooted itself so that was a no show. Ill try to up the voltage even more, probably what dragonsprayer said, thank god I have the whole day off today so im gonna try to get this bad boy to work with me xD. Will post results as soon as I can. Thanks agian guys.
  14. First you need to get the temps under control, CPU not over 65 under load. I would first try reinstalling the CPU heat sink. What type of thermal compound did you use? If AS5, try reinstalling using the following guide:
  15. Ok after so many hours yesterday of taking everyones advice im basically still where i started. I looked all over where I live, Ottawa(Canada), and no one sells a freaking thermalright Ultra 120 -_-. So that was a no go and than i tried up the voltage as dragon said....I wasn't suprised with the results at all, obviously a no go. So Ill try reinstalling the Heat sink and yes I did use AS5. Will try later on tomorrow, ridicously tired after a 12 hour shift >.<. Thanks agian. Thanks for the link Foes.
