I have a Sony laptop (bx297xp ) with a 2GHz Pentium M but it only shows 798mhz ? :confused: Is this normal & it increases as needed ? could I fit anything bigger in there processor wise ? It has a Pentium M 760 2GHz
 
It sounds like speedstep is enabled, go into the BIOS and turn it off should run at full speed after that. Only do this if you require the full speed.

so it increase as I need it otherwise ? Is there a more powerfull processor that I could fit ? using it for gaming etc


yes load the cpu with prime95 (or similar) and it will bump up to 2ghz... speed step saves battery.

(use cpu-z to check if you want)
 
If you need the full speed just disable the Speedstep in the BIOS you should get the full 2.0GHz out of the processor but the battery will drain quicker with this method.

There is no harm in disabling the Speedstep and won't effect the hardware in anyway or your warranty if you still have one.
 
Also, your laptop might enable you to change the power profiles from Windows to save going into the bios. Have a look at the software that came with it, there might be something from Sony that lets you change things.

Notebook Hardware Control. No Pentium Laptop owner should be without it. :p

Speedstep is enabled by default hence why the CPU speed is 800MHz when not doing much. This feature helps greatly improve battery life. When the CPU is called upon to do more demanding task, the clock speed will automatically ramp up to top speed.

That software is great because it allows you to set up profiles. Mine are like this:

On Battery: CPU speed is locked to 800MHz. I don't do anything demanding when on the battery so this speed is perfect when browsing/using MS Office on the move. Helps massively with battery life.

On Mains: Speedstep enabled. You can if you want set the program to lock the CPU speed to its maximum when plugged into the mains.
 
Noticed this recently with mine as well, not sure why I didn't see it before, processor was operating at 1.6ghz when it should have been 2.8ghz.

When the power settings are set to "Max Battery" or "Laptop" or anything like that the fsb multiplier goes down.

Just select "always on" in the power settings or by simply left clicking the battery (or cable) icon in the system tray to raise the speed again.

Lowering the FSB multiplier gives an added hour to my battery life so it is worthwhile keeping the intel speedstep enabled.
