Basic Guide For Overclocking Q6600 on Asus P5K-E (and similar) Motherboards

Ok make sure you have the DRAM Command Rate set @ 2T (might be 2N if you have a latter BIOS) if that fails...

set your FSB to Northbridge Strap to 333mhz and readjust your DRAM Frequency so it is @ or under 400mhz (might display as DDR2 Rate In which case under 800mhz)
 
well Asus boards tend to be most stable on the 333mhz strap, if your board runs a 400mhz strap you could try that to get 800mhz on the RAM...

best way is to I guess run some quick tests and see what gets you best results I am not sure tbh...

Alternativly you might consider overclocking a little would increase base FSB speed and therefore RAM and CPU speed.. Not sure what CPU u have? but on a stock cooler and Q6600 you can get to 3Ghz easy normally just by upping FSB to 320 :)

Q6600, no 400mhz strap for me, 333mhz is max, set the FSB to 320 so RAM showed as DDR2-768, however with 4-4-4-12 2.1v I got a "NTLDR is corrupt" error when trying to boot, booting on timings set to 5-5-5-15 (still 2.1v) was fine and the CPU showed as 2880mhz which is a start I guess. Could it be the board? G35 chipset etc??

edit: I'll push it further when I have proper cooling cos can't be dealing with this stock cooler, it's the loudest thing my system and now I've OCed slightly it's even louder!! Notice you have your fans at 3500 rpm at that overclock, you'll lose your hearing with that racket lol!!

Try with 2 sticks I guess it could be the Northbridge on the board not being up to it?

Well 24/7 i run a 3.825Ghz clock and my fans even @ 100% load (folding at home) run at around 1400RPM which is not to loud at all certainly quiter than the G/Fs 2 year old AMD system that sits next to it
 
blend is good for testing overall system stability but to make sure you want to run a good few hours of Small FFTs as well.. this will really stress the CPU and will load it to the max, you will note that your temps will be high on a small FFTs run as well..

But overclock looks good :)

If your feeling brave you might consider looking at the base of your heatsink / the surface of the CPU as you have some variance in coretemps there.. a bit of lapping would probably see 45/46c across the board and give you some more headroom.. :)

Glad you found the guide usefull feel free to post about anything you think needs more explaining etc..
 
just keep on increasing the FSB and running through the prime95 test cycles.. once it fails you will need to add more vcore... keep an eye on temps and make sure you keep your RAM under it rated frequency
