Core speed/Multiplier keeps Alternating?

XPS M1530 2.2GHZ T7500

Checked my system with CPUZ before replacing my CPU with a Penryn X9000.

I noticed the core speed and multiplier kept alternating between 2194.6MHZ with a x11.0 mulitiplier to 1197.1MHZ with a x6.0 mulitiiplier. It keeps doing this continuously. Surely this cant be right? I must be losing loads of performance. My desktop system doesnt do this and stays stable.

Anyway, I went ahead with CPU swap and the problem still remains just with different frequencies and multipliers.

Is this something that can be altered in the bios? if so, how do you access the bios on the XPS M1530 or is this something more synister

Thanks

Just noticed when pulling up webpages and still running CPUZ when the core speed/multiplier drops the web page hangs and when they rise the page loads instantly. hhhhmmmm.

 

It's called CPU throttling and is normal - when ya doing something the CPU runs full pelt, when you are idling it reduces the speed to save power and run cooler.

 

Ah good news! If this is the case, why does my desktop not do it? Is this a laptop thing? As you can tell this is my first laptop, although i have built several desktops.

 

All processors should do this.What's ur desktop processor?

You can install notebook hardware control and it will take care of the rest.

 

its a Intel Core 2 Extreme Quad-Core QX6700

 

Are you set to high performance or power saver. That could be the issue.

 

You don't need notebook hardware control on desktops, it works automatically if enabled in BIOS.

 

It's called SpeedStep and often disabled in desktop computer BIOSes. You can enable it on your desktop by turning on EIST and C1E in your BIOS. Be warned, while it will lower power consumption while idle, it can also disrupt overclocking and will make your desktop a little more sluggish as it toggles back and forth on the speed.

 

Turning off SpeedStep option also get the same result. My T7250 running at 1197Mhz @x6 multiplier
