I'm sure I'm just being a bit dim here but according to CPU-Z the multiplyer of my E6600 keeps moving from x6 (2GHz core speed) to x9 (3GHz).
Is this normal? How to i get rid of it? Should i get rid of it?
Motherboard is an ASUS P5B

Thanks for any help

Why? :confused: It shouldn't slow your CPU down when you need the performance, but it will make it run a lot cooler and use less power when you're just surfing the net. It's a great feature.

Quoted for truth. You don't need a huge clock speed when you're only browsing the internet.

It's not like it makes your PC unstable either.
 
My amazement at the number of people who ask why their processor speed is adjusting all the time is matched only by my bemusement at those who feel the need to turn it off.
 
I have the equiv feature off at the moment on my Phenom setup as there were some annoying cases of it lowering multi, or at least juddering, during times it should have been full speed. (Definately caused by Cool n Quiet)

I have never experienced any issues with speedstep on any Core/Core2 CPU's, it's a great feature and iI don't understand why people turn it off.
Really need to sticky the MY MULTI KEEPS CHANGING topic...
 
Personally I leave it on, saves power and also saves you money on your electricity bill. When you switch on a game that uses your CPU it will use full speed so theres nothing to worry about. It uses its full speed when you need it.
 
some games that arent intensive all the time on the cpu will let it dumb down with speedstep and c1e on...

hence losing albeit slight performance but performance never the less

+1

There is no need to turn it off at all, it will still give you the performance you need when you need it, and saves you power when you don't.

And a little search of the forums never hurt, I reckon that one in ten threads in the CPU forums are exactly this question!
 
Well when playing a blu-ray disk I was getting a fair bit of stuttering. When I checked the speedstep change was kicking in and out all the time. I guess the movie playing was on the borderline for the speedstep limit/trigger.

Disabled it in the bios which resulted in smooth film playback. One of the "perils" of low cpu usage with gfx card hardware acceleration I guess. :D

BluRay playback should be taken care by the GPU? If the CPU usage goes up while BluRay playback this probably is a good indication that the GPU acceleration is turned off or the software is not doing its job properly.
 
Here is a simple check of how speedstep can affect software you use a lot. I use WinRar to compress and extract big files often. Use WinRar or WinZip to compress a large file or folder (3 or 4GB). Then with speedstep on and not running other applications, except maybe CPUZ to watch the multiplier, decompress the file and time how long it takes. You will find that the multiplier stays at x6. Then turn speedstep off, decompress the file again and notice the 30%+ improvement. Now tell me I don't need to disable speedstep.
