im trying to overclock my Q6600 CPU. i couldnt do it before because the bios needed updated so i updated the bios to the latest version and booted up i entered bios and attempted to change the fsb speed. I worked out what to put the fsb to by doing this 1500(fsb) divided by 4(cores)=375(bus) times 8(multiplier) to get 3ghz. I saved the changes and restarted, i entered bios and made sure it was done and sure enough it said 3ghz i then ented windows and started CPU-Z and got this: http://img337.imageshack.us/img337/5919/q6600.png

i repeated the process several times and even changed the bios to an earlier version but still no luck. PLEASE HELP

also i cant get the ram speed to change. i dont have c1e or speed step enabled

this is a repost to try and get more answers

Have you tried overclocking it at less than 3GHZ?
Sometimes it may be to much of an overclock and the motherboard can keep running at stock even if you changed it.
Try starting at around 2.5Ghz and keep going up

 

[JY]

yeah iv tried that. iv tried everything i tried disabling all of the cpus features like executable bit etc. it overclocks fine with a pentium 4 in it but it just doesnt work with the q6600 for some reason even though its officially supported

Have you tried loading and applications as it may be in idle clocks ( lower than the OC) have you changed the voltage that is going to the chip as it you don't the cpu will be unstable.

 

[JY]

yeah i have raised the voltage from 1.24 to 1.31. i cant run intel burn because it just makes the pc turn off.

 

[L3gacy]

What kind of temps do you get?

that's way to low for a 3GHZ OC there's your problem you need to bump it to 1.45, then try again 1.5 is the max safe and and I say safe a bit dubiously as 24/7 1.5 on air is not what you want also get real temp

And report back with what you get.

the problem is that the bios isnt actually changing the values so i cant run any kind of tests because it is at 2.4ghz and i CANNOT change it and i dont know why. its as if the bios cant control the hardware for whatever reason

 

[JY]

like 30-40 celcius

What VID is the CPU - as i see it is a B3 revision. 30-40 C idle for B3 is pretty cool. Something is not right - can you post pics of the BIOS changes and the Vcores.

 

[JY]

do you mean i picture of my actual bios menu?

This is totally untrue, unless you have one of the worst Q6600 ever made.

I used to have a very similar board and sometimes it did the same thing. Do a hard reset of the Bios by pulling out the bios battery and also disconnect the power supply from the motherboard and leave it like this for at least 30 seconds. Then reconnect everything and try it again, but dont OC on the first boot, wait until the second at least.

 

[Vipervlv]

Yes, or at least rewrite the avaible options that you could change.

 

[JY]

didnt think of that. ill try

 

[JY]

ok im uploading pics to image shack. give it a couple of mins, super slow upload speed

 

[JY]

it seems to have only uploaded 2 but cpu vid is 1.224 and everything else it auto

 

[Vipervlv]

1.325 Vcore is pretty high for first try for overclock especially when you CPU VID is 1.22 - it is 0.1 high. Change the voltage of the memory and the other stuff to default values - lowest. You could try to star overclock from low end - lower the DDR frequncy to 667 and start rising the FSB to see whather you are making something at all, and keeping the Vcore at around 1.24 or 1.25.

 

[Kirby1]

Your CPU has a lower VID than mine and I'm running at 3.6 so your CPU is good. Did resetting the bios enable you to OC or still same issue?

 

[JY]

i reset the bios and started but it said CMOS checksum error and i presses f1 to continue boot. still the same problem

well I had the worst ever made then.
