I just built myself a XP 2500+ rig with a MSI K7N2 board, crucial pc2700. Anyhow, I wanna oc but how do I know if the cpu is locked or unlocked?
 
I will try to see what the build date on mine is. I tried to the multiplier change but it only locked the pc where it wouldn't even post. I'm assuming...if the cpu was locked then it would have just went to the defaults.

Why did you get PC2700? Maybe you already had it.

Yeah I already had the ram. I think I should go with something faster though if I wanna oc successfully. Any suggestions?

My Crucial 2100 (133 Mhz) stick goes to 200 Mhz (just barely) with looser timings (CAS3). I was a bit shocked when I kept bumping it up 5Mhz and it wouldn't crash. I expected a little over 166. It'll run prime95 indefinitely at that speed, but pushing it to 202 is too much, and I don't care to run things right at the edge (except for fun). You don't drop a lot of performance with looser timing, it's just that OCers tend to want everything as fast as they can get.

The PNY 2100 stick will only do about 190 at CAS2.5 completely stable. For some baffling reason it crashes (won't boot) at about 140 or over if I set it to CAS3. Yeah, it tops out higher at tighter settings.

Unfortunately the Crucial needs CAS3 at 187, so I run them together at CAS2.5 and 182 MHz.
