Q6600 refuses to overclock!

post #1 of 3
Thread Starter 
Howdy guys and gals!

Although I've got about 25 years of experience with computers, I'm new to the hobby of overclocking. I had toyed around many-many years ago with much older processors, but now I remember nothing. So, although I don't know the "hows" of it, I can understand whatever info, guides or buzzwords you through at me. Why all this intro? Well...

I've got two PCs. I'm leaving my "current" one untouched (a core i7 2600K), but I want to overclock my previous one. So... Hardware first:

Gigabyte X48-DS5 with 8fc BIOS (if I remember correctly its version - the latest one I could find "officially").
Intel Core 2 Quad Q6600 (Kentsfield) (Revision G0), running at full load un-overclocked at 55C-60C with a Hyper 212 EVO I just added (I live in Greece, so that's with a 35C ambient due to the wonderful Greek summer sun - oh, how I'd like some snow!)
GPU: GTX280
RAM: Mushkin DDR2 PC2-6400 (Model 991593 (996593).

Here, let me add that I bought this RAM specifically to be able to overclock my PC, as it'd got great reviews (when I bought it, some years ago), but was struck seeing that whatever I did it couldn't run at its advertised 1066 speed, but only at 800MHz.

Now, I've followed a bunch of guides and I mixed and matched info I found here and elsewhere, trying to push a bit my CPU (and maybe set my RAM straight). No go. Whatever I do, after one reboot, where it shows its new speed, it re-reboots reverting to its default values. Everytime.

What I did (copied and mixed from the guides/info I found):

"CPU Enhanced Halt (C1E)" to "Disabled"
"CPU Thermal Monitor 2 (TM2)" to "Enabled"
"CPU EIST Function" to "Disabled"
"ACPI Suspend Type" to "S1(POS)" (for now...)
"HPET Support" to "Enabled"
"HPET Mode" to whichever OS type you're running - "32-bit" if an x86 version, "64-bit" if an x64 version...


"Robust Graphics Booster" to "Auto"
"CPU Clock Ratio" to "9" (Also tried 8 with 300MHz CPU, witch should give THE SAME speed as my CPUs default. No go: rebooted again and reverted to the defaults).
"Fine CPU Clock Ratio" to "0" (I don't have that setting)
"PCI Express Frequency (Mhz)" to "100" (not auto...)
"CPU Host Clock Control" to "Enabled"
"CPU Host Frequency (Mhz)" to "266" (played with different numbers - toying with speeds from 2,4GHz to 3,2GHz - no go, none of them, nada, zilch).
"C.I.A.2" to "Disabled"
"Performance Enhance" to "Standard"
"System Memory Multiplier (SPD)" to "XXX" (where "xxx" = "whatever gave me 800MHz RAM speed depending on the speed I set on the CPU")
"Load-Line Calibration" to "Disabled"
"CPU Vcore" to "1.325V" should be good...
"DRAM Voltage" (I added up to "+0.2V", I'm afraid to push it more)


Aaaand I also did the following someone, somewhere said would help:

Go to main BIOS page, and do a - screen should 'flicker' once; go to "PnP/PCI Configurations" page, and you should show a new item - something like "PCIe Timing blah blah" - can't recall exact wording - will be 'defaulted to "32", and have "64" & "128" settings available - 'bump' to "64"...


Playing around with different speeds, adding a bit to the CPU voltage and/or the +0.05 / +0.2V to RAM I mentioned... Nothing. I always see ONE restart with overclocked values and right where it tries to "test the memory", during boot, exactly after the POST mentions the speed of the CPU, it restarts back to its default values.

And the strange - and infuriating - thing is seeing gazillions of posts mentioning how awesomelly overclockable both q6600 and this Gigabyte mobo is. What am I doing wrong?!

And, apart from all this, does anyone have any ideas if there's any way to get some more juice out of this PC in other ways? Can I also push or mod the GPU in some way? Would I get some more resources if I disabled the onboard Azalia sound system and used a Phillips Seismic Edge I've got lying around?

Any help would be greatly appreciated.

Thanks in advance for any comment and info.

Does your board offer any auto overclocking features?
From memory, I believe the Q6600 G0 SLACR version was a better overclocker anyway.

I owned one previously and the only way i could get it to overclock and boot properly was to enable the Auto OC feature i had on my ASUS mobo at the time.

Reset everything to default and only change the FSB. Most Q6600 can do 3.0Ghz on default voltages so try there. Heat will be your main problem and you may not get much more out of it as your heatsink is decent but not one of the better ones.
