Issues with overclocking the Q6600, changes do not apply.

post #1 of 15
Thread Starter 
So I tried changing my bus speed from 36xx-400 and my my multiplier from 8-9. Everytime I save and exit the bios settings my computers tries to reboot and fails 2 times, then on the third time it gets running (my asumption is that it tries to automatically find a comfortable voltage since I have auto voltage turned on) and then when I check Cpu Z or real temp my fsb is at default speed but then when I go back to the bios its set at the speed I set it. Anyone know whats wrong ?

Sounds like the BIOS is resetting from a failed overclock. Some boards do that, if they fail to boot XX times they start up in a "failsafe" mode.

Auto voltage is very unreliable, you have a heavily unstable overclock, control the voltage.

Also, by the sounds of it, you've jumped from 2.4GHz to 3.6 in a single step, that's unlikely to work unless you have significant OC'ing knowledge or previous experience of the board and chip.

What revision is your Q6600, that will help determine what voltage you can expect to be using. If it's a B3, I'm sorry for you, max v-core is 1.55, but mine took 1.4volts to get stable at 3GHz, if it's a G0, max recommended is 1.45v, but they require a lot less voltage for high clocks.

One thing I learned earlier is to increase voltages BEFORE performing the overclocking. You need to make sure you can run a system at higher voltage before making it even less stable from overclocking.

Another thing that can happen is that some RAM just doesn't like to be messed with, and will get cranky and crash on you. I had several overclocking adventures cut short by ram that really didn't want to be run at anything other than 1066Mhz (it was 1333Mhz ram, go figure). In this case you may want to loosen up your memory timings by hand. Start with their standard spec and add 2-3 to each timing to be safe.

Lastly, a lot of beginner overclockers neglect to increase the MCH (northbridge) voltage. Usually a .1-.2 volt increase is enough to get you running stable. My MCH is stock 1.1V, I put in 4 sticks of ram so it needed 1.2V, then I OC'ed my cpu and it needs about 1.28V.

Just some tips from the new guy at overclocking.net smile.gif

I did not try to go to 3.6 in a single step, max was trying to get to 3.2. Anyway I will go slower now, first to 2.8 and so on. I have the B3 revision, as far as I want to go is 3.4 in the end.

That's cool, may be useful to look at the voltage you had at 3.2 on auto settings if that was stable.

What are the rest of your settings in the BIOS?

The max I could get was 2800, and Im not sure if the voltages even apply as they should, even if I leave everything on manual.
All my settings are at default (the +01v etc settings for raising the north bridge and such voltages, I will tinker later with that, post 3ghz I asume) but im not even sure if the cpu voltage I set applies, it always overrides and am not sure why.

9x310 is as far as it lets me go... after I change the 310 to 315 nothing works..., if I keep it set to auto it fails, if I crank up the cpu voltage to as far as 1.4 it still does not work (which is strange since with 9x310 the voltage defaults to 1.3444, then I tried increasing the dram voltage, fsb voltage and north birdge (at least I think that was the option for it) by +0.1v but still nothing. I have a B3 revision, dont know how high I can set the voltages.
