Cpu-z says my multipler is changing on the fly!

[godisturbed]

Hello everyone, this is my first post here.

I built my new system a couple of months back with a GA-P35C-DS3R motherboard and have had no problems with it until today (unlike a lot of u by the sounds of this forum!)

I had overclocked my FSB to 333 mhz to give me 3000mhz speed on my e6600. Didnt change any voltages, system booted fine and I have played through Bioshock like this. However, today I downloaded CPU-Z and to my horror it is reporting a varying clockspeed - mostly it is 2000mhz with a multiplier of 6 and then every now and then it jumps to 3000mhz with a multiplier of 9. This jump seems to happen when the core voltage gets above 1.25. The vcore is varying from 1.185 to 1.325 (mostly 1.2)

So I went back to stock FSB speed of 266 and the same thing is happening - multiplier is going from 6 to 9 with vcore changing.

I then downloaded CoreTemp and that reports my vcore as 1.35 with proper speed of 2400mhz. I also have Intel Thermal Analysis tool and that reports 2400mhz.

So is there something wrong with the CPU-Z program or is there something wrong with my voltages? CPU-Z is giving me this conflicting information while the other programs report the speed as it should be. Any ideas?

It's a power saving feature of your Mobo - When the Processor isn't under much load, it steps down to save on power/heat. You can disable it in the Bios if you want, but as long as your system is otherwise stable there's little reason to do so.

thx for the swift reply, i actually just figured it out a minute ago. I played bioshock in a window and saw it going upto full speed so everythings ok.

yeah my mobo does that to. i'd just leave it alone if i were you.

it's normal and all fine and dandy and I'm drunk too

LOL you people are wooses...I dunno.

What's happening is that C1E and EIST are trying to save power by cutting back your multiplier. The fact is that if you don't need 333x9, the chipset won't give you that. If the system requires more speed than 333x6 can provide than it'll kick it up. It's alot like an auto-trans on a car or truck, it'll shift to give you less power when you don't need it, but more efficiency and give you more power more for when you do.

ryanthesav, you are a TROLL.

@ OP it's EIST Intel Enhanced Speed Step. You can turn it off in BIOS if you want.

Do you guys disable it or have it enabled? I'm the kinda old fashioned ppl so I have it disabled...

 

[mitch074]

Enabled. Lower power use = lower CPU fan speed = less noise, no performance impact.

I have mine disabled right now, but I'm thinking of enabling it. They say if you are overclocking then you need to disable it for stability, but I think they are talking about aggressive OCing. I had three Q6600 OCd to 3G/1333 with ram at 4:5 1666 effective and EIST turned on with no stability problems, but that is not a very aggressive OC.
