Help Overclock Q6600/GA-P35-DS3L

[Storx]

Ok, I am a bit of new still to oveclocking but i have successfully done it on my prior computer for over 4 years of stable computing tell it died when the cpu fan failed. But anyways for the life of me i cant get my new PC to budge any on overclocking it.

This is the Setup:
Q6600
GA-P35-DS3L
PQI DDR2-800 2Gb
EVGA 8800GT SC
Case: Antec 900
CPU Cooler: ZeroTherm Nirvana NV120 Premium Black Edition

Here some pictures i snapped after playing some WOW for a few hours.....when i started looking into the bios...

These were taken after a few hours of gaming i was cursious to see what my systems temps were running at....

This one is a picture of the stock Bios settings....

The thing is i cant adjust the FSB at all without it restarting twice and defaulting back to stock... Am i missing something

The Values i was trying to reach was 3.0Ghz
CPU Clock Ratio: 9X
CPU Host Freq: 333Mhz
PCI Express: 100Mhz
System OC: Standard
Memory Freq: 667 (DDR-2 333x2=666)
System Volt: Auto

Perhaps turn off Speedstep? It's called something like EIST...

Also set voltages to manual, perhaps the auto voltage is over-volting the memory.

I have this board and chip and got 3ghz out of it no problems.

Keep voltage at auto, it works great. Mine automatically raised mine to 1.33V

CPU Host Clock control needs to be "enabled"
CPU Host Frequency 333

System Memory Multiplier - Change this until the number on the right reads around 900-1000, depending on what you think your RAM modules can handle in terms of overclocking.

Ideally you would purchase some nice 1333Mhz ram so your system memory multiplier can be set to maximum.

hmm.. i wandering what it is.. my cooling is doing well im seeing maybe 39C at game load full HD graphics....
I did some fiddling and if i enable CPU host and set the freq to 266 it works fine.. the minute i move it to 267 it will not boot... its driving me crazy....

I've got the same board as well, only with a P4 631 3GHz that I'm getting 5GHz stable with. Quite a nice board.

First: Lock your PCI-E frequency down to 100MHz. Disable SpeedStep/EIST.

Here comes the wash, rinse, repeat section. Push your FSB up 5MHz. Restart, boot into Windows, shut down, push your FSB up 5MHz... you get the picture.

The moment it refuses to boot at the setting you try (e.g. 291MHz) ramp the CPU voltage up by a notch or two. See to cooling when you start mucking about with the voltages. This point cannot be stressed enough. Once you've ramped the voltage, and it's booting stable, run 3DMark, then run Prime95 for 2~8 hours.

This is how I got a P4 631 3.0GHz at 200MHz (1.35V) up to 5.01 GHz at 334MHz (1.54V). I'm going to install my second radiator soon and try for 6GHz.

The refusing to boot over 267 is probably either voltage or your PCI-E frequency not being locked down.

If tweaking the CPU voltage doesn't work or stops working, change your RAM multiplier to bring the frequencies down OR loosen your latencies. You can also overvolt the RAM.

Hope this helps.

I wish you luck, 5ghz stable is incredible, even for higherclocked netburst-based CPUs

ok.. i fiddled around with it... and i have come to conclusion that its my memory that is causing it to not post... well i think....I can leave everything stock and change the multiplier on the memory and i tried every single setting and the only setting it will boot up on is in Auto... unless there is a feature im missing that is preventing me from overclocking or underclocking my memory... its pretty gay cause i used PQI memory on my old PC and was able to overclock the crap out of it and never had one problem....maybe they have gone down since then in stability....

see what the recommended timings (4-4-4-12, 5-5-5-15, etc) for your RAM are...You may need to manually adjust those if you undo the "auto" for the RAM speed and run asyncronous.

 

[Mugz]

Maybe give the RAM about 0.3V extra juice, if you haven't already done so.

well today i spent countless hours playing with it and finally got it to start moving the FSB.... I had to adjust the voltage .3V for the memory... and i also had to increase the timming from 5-5-5-15 to 5-5-5-18 and i was able to walk the FSB up from 266 to 268 before it wouldnt post anymore.. but when i checked this the memory was really warm so i back it back down to stock and going to leave it here... for now..

So i purchased Some Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model BL2KIT12864AA804

I plan on swapping the memory out got it for a good deal 1gbx2 for 39.99.....
Hopely i can get some better results out of this memory... has anyone had any use with this memory.. what timing are you running..
