So I decided to OC my 6600! As it stands I've simply set the FSB to 400 for a 3.6Ghz clock speed and left everything else as normal. A screenshot of CPU-Z is below, can anyone with more know how tell me if the settings seem about right? The core voltage and FSB seem to be fluctuating slightly, although as I type this the CV is sitting steady at 1.416V. The multiplyer seems to be changing from 6x to 9x changing the clock from 2.4 to 3.6.. Any idea's how I can stop this? Think there is a setting in the BIOS I was meant to tick.. going to go try that now and see what happens, just noticed that screeny is showing 2.4 so I'll change it in a bit. Temps seem fine too.. Although I havent put any strain on the system yet other than re-doing the Vista score thing (putting each core at around 90% usage and the temps to around 55c).. They're idling at 35ish. Any thoughts?

Disabled one setting and set a static multiplier to 9x and the following cpu-z was the result. the FSB is dropping to 1599.9/8 from time to time obviously taking the CPU speed with it, but at least the multiplier is solid now. -- Edit -- Think I spoke to soon. My system stopped so I hard reset and decided to set a solid core voltage of 1.4. BSOD on boot, so I tried a few voltages around that sort of area all resulting in no boots. Ive gone back to auto settings (e.g. no OC) and the system has booted, so clearly something is wrong with the settings causing instability. Any thoughts, at this stage I dont know what to look at to help stability.

Ew, you're using vista Anyway I have my fsb at 1350 with a bus speed at 340 c.volt at 1.376 giving me 3,1ghz yes not a fantastic oc, but it's stable for me on my E6600. I need my computer to run 24/7 if I want it to without suddenly rebooting. Educate yourself Give an internet to NFOHump!

You have multipler roller coaster due to Power Saving features. Disable the SpeedStep / EIST thingy in BIOS.

lol yeah.. Oddly enough its the only legal license I have and I wanted to use it to keep away from all this M$ illegal version bullshit.

They were already turned off, I think it was due to the MOBO's auto OC'ing options having 2 possible multipliers set (6 and 9) so it kept skipping between the two as needed.

Anywho, one of the BSODs indicated a page fault in a non-paged area. Then it dawned on me, my memory setup was set to 1:1 so with every FSB overclock the RAM FSB was going up too. I've set it to static at 400Mhz and now things seem to be a little more stable, Vcore set back to auto (so its skipping from 1.4 to 1.425).

You don't mention what kind of memory you're using but I'm guessing it's pc6400 (or better) so running an FSB of 400 shouldn't cause any problems there. Your voltage fluctuations are being caused by another bios feature called C1E which you should disable. It's a power saving function which interferes with overclocking. Lastly, you should start from lower values in terms of both fsb and voltage to determine the limits of your system. If a particular fsb/voltage combination doesn't pass the stability test then just pumping more voltage through the system won't solve the issue. It could well be that you've reached the limit of your cpu/board.

Nice OC, btw what do you use for cooling to have only 19°C for the cpu temp?

I have a Q6600 done with the standard overclock. 3.2ghz, 8x multiplier, 400fsb. Runs fantastic... at 36°C under load.
