Overclock 101

Maybe speedstep or whatever they call it. I don't have that board so I don't know what options are in your bios tweaking I'm sorry. If thats what it is don't stress too much, it can be disbaled though some folks leave it on. All it does is slow your processor down when it's not needed to save on power and then brings it back to full speed when needed.

Also some programs read the multiplier kinda weird anyways. The good news is from those pics that your Q6600 is G0 stepping model.

Do try something like Everest for monitoring temps though as those programs only show you the single CPU temp not the individual core temps. They will be higher and they are the ones you need to watch.

Look at the image below, see how the CPU (in blue) is reported as 29C when in-fact the actual CPU cores (in red) are almost 10degrees higher. Don't trust the single CPU reading as you don;t have a single core CPU.

oh thanx man.
what u said was right my mobo has some feature called NOS so it bascially underclocks your system to save power and overclocks it only when needed....kinda

 

[sahitanand]

k now can u explain to me what a G0 stepping means?

also as soon as i start up and if i check the speed it shows 266 X 9 then after a while it shows 266 x 6
whats happenning??

That is a Power Saving feature called "Speed Step" which is a feature of the chipset/Bios. What it does is sense when the computer isn't under much load, at which time it turns the power/speed down. When the load on the machine picks up, it changes back to full speed.

You can disable it in the Bios (SpeedStep and C1E), but for mild overclocks there's no real reason to. Except maybe you just don't like having a display showing your numbers change...

For Stepping: Think of it like point releases on software, except in the context of a processor. These can occasionally be physical changes in the design or manufacturing process, or more often changes in the microcode instructing the processor how to run.

In the case of a Q66, as already pointed out, there is B3 and G0. G0 is better, and if you bought your processor/computer after last November or so then chances are you have a G0. B3's run a touch warmer, and overclock a hair less than a G0. But IMHO, it's irrelevant unless you are going to go for an aggressive result. You can overclock a B3 just fine.
