Processor is not even close to stock speeds.

So I ran a "Can You Run It?" program on my laptop to see if it could play Crysis. After it was done everything said that it could run it except for one thing and that was the speed of the processor. I read it and it said 798Mhz. I thought this was a mistake because the speed of my processor is supposed to be at 2Ghz. So I ran CPU-Z and it seems that the website was right. So what's wrong and what can I do about it? BTW this is a Dell Inspiron 9300. Here's a screen shot.

OK so I just looked up on Wikipedia my processor and apparently the multiplier should be at x15. I have no idea how it got to x6. I haven't touched anything in the BIOS or anything. As a matter of fact I don't think dell BIOS's let you mess with the clock speeds.

Your CPU is fine. The reason it's not showing the full clock speed is due to Enhanced Intel Speedstep Technology (EIST in BIOS). EIST will scale back the CPU speed when it's not in use to conserve energy and run cooler, thus cutting back on the constant drain. If you were to have CPU-Z open and then opened a CPU-intensive program (Adobe, Outlook, AV scanner, etc.) you would see the multiplier shoot up to 15 and the clock speed reach it's full speed.
 
laptops also underclock themselves when they aren't plugged into a power source. its to save on battery life, depending on your motherboard and etc... but dell and intel centrino technology does that. and also, yes your cpu-z will read a lower clockspeed if you have eist enabled as imsati mentioned.
 
geez, i replied to one of these threads like a couple of days ago. there should be a sticky about speedstep/cool n quiet

Also, whether they do or don't, and how much they do, depends on power saving settings - you can turn the CPU power down while plugged in or turn it all the way up even when unplugged.
 
yeh my quad is overclocked to 3.2ghz and it drops down to 2.1ghz when not used!!!

nothing to worry about really

Thanks for clearing that up, but I have one more question. I thought that the clock speed of a processor was the FSB multiplied by the multiplier. In CPU-Z, seen in the picture above, the multiplier is being multiplied by the BUS speed, which I thought was something different. Sorry I'm a noob, what do I have wrong?

:P

See,
5x2=10
2x5=10

2x12=24
12x2=24

3xA=3A
Ax3=3A

AxB=AB
BxA=AB

It doesn't matter which way around they are - it's still the same thing. Makes no difference - usually people do say "FSB x multiplier" rather than the other way around but still, as in any multiplications, it doesn't matter which way around the numbers are. So, it's not different in any way.
 
I think you are confused about what the difference between "BUS speed" and "rated FSB". bus speed is the raw FSB or actual FSB. everything is based off the raw FSB, so to determine CPU speed, you take the raw FSB and multiply by the CPU multiplier.

intel quad-pumps the raw FSB to get the rated FSB or the effective FSB. quad-pumping means that data is sent 4 times every cycle, so it effectively looks like a 4 times faster raw FSB. on your processor, the rated FSB will always equal 4 times the bus speed.

a way to think about this is imagine a bus going around a bus route. how many times the bus completes the route in a second is the bus speed. quad pumping is like putting 4 bus on the same route at the same speed and equally spaced out along the route.
