Sempron 3300+ What should its speed be?

I am curious is to what the sempron 3300+ speed should be. Mine is stock and reads 1.00Ghz. Is that normal and if so can I make it faster? (Without burning anything out in the process.
 
Your processor is supposed to run at 2.0 Ghz, not 1.0 Ghz. Either you've got Cool n Quiet turned on in the BIOS (thought the Semprons didn't even support that), or you've got your cpu multiplier set too low. Try checking your processor's speed while running this: SP2004. If it still runs at 1.0 Ghz, then you've got your BIOS setup wrong.
 
Cool and quiet is working. Works with sempron 3000 and higher. I would leave it alone. The cpu will automatically increase in speed as needed to about 2.0.
 
Lucky you, my semperon 3000 won't go lower than 1.61Ghz. How low does CPU useage have to be for cnc to start kicking in?
 
I have it running at 2.25 Ghz now, is that going to hurt anything or am i going to be okay with this speed?
 
As long as you are stable all is well. When overclocking it is nice to 'stress test' the CPU to ensure that it runs stable at the higher speed. Getting an increase in speed, but having the PC freeze up or reboot during an important task is useless in my opinion.

The 'standard' that most people who overclock use is 'Prime95'. Just download it and run it (there are instructions on the webpage). If you can get over 8 hours with no errors, the CPU is pretty good. If you can get over 12 hours you will most likely never see a problem with it. If you can get over 24 hours with no errors, most everyone here would call that 'rock solid'.

Personally, I like to have a temperature monitoring program running while I am overclocking and stress testing. I usually benchmark the PC and note the temperatures while the CPU is running at stock speeds and then again when I am overclocked and stress testing. This way I can gauge my increases in speed with my increases in temps.

EDIT: BTW, I had two Sempron 3100s running at 2250 (9x250) for months. I needed to increase the vcore by 3.4% in order to be stable, but there were others who were able to run at that speed with only a 1.7% increase in vcore (using the ECS NF3 / Sempron 3100 combo that Frys/Outpost.com had a while back). Plenty of us ran at 2250 for months without any problems.
 
What motherboard and how much? Post the deal in For Sale (remember to read the sticky on rules).
