My sister ahs this in her rig. It runs at 2.66 by default, i can get it to run past 2.8, i don't know why. I evne tried insane voltage levels.

has anyone OC'd these before?

oh, I'm using an MSI P915 Combo Motherboard
 
I'm guessing you probably just hit a wall. That chip may not be capable of any substantial overclock.
 
I wouldnt, some cpus just have a wall, and its a celeron, i wouldnt be surprised if it had a wall. theyre not very good chips. not meant for overclocking.
 
Overclocking varies chip to chip, but even lower clock speed 90nm Prescott-based Celerons have always done over 3GHz easily for me. I'd guess not enough cooling, unoverclocking friendly memory or a dud chip as the likely problems. Have you tried lowering the memory speed or checked the heatsink to make sure it's mounted properly?
 
I had a Celeron D 320 (2.4ghz) running at 4.0ghz on a Abit IS7.
 
Intel's 915 chipsets were crap for overclocking. That board in particular is a budget design, so it's even worse.
 
so its the board? crap. explains why my Pentium 4 520 wouldn't OC on my old alatron board with the same chipset...

the memory is my old set of OCZ platinum revision 2. its actually being underclocked because the board only supports 533 DDR2. Currently i'm suing the stock CPU cooler, its not running that hot. like maybe 55C under load i think, thats with the 2.8 ghz OC.

The 915 chipsets supported 800MHz FSB, so overclocking a 533MHz FSB CPU isn't being limited by the chipset until that speed (and his Celeron D 331 probably wouldn't get to 4GHz anyways).

If the board is limited by the overclock lock as the OP suspects, that's pretty crummy. There is an option of replacing the CPU with a faster stock speed model. I see a 90nm Celeron D 350 (3.2GHz) on pricewatch for $44 shipped. Or you can hit up ebay for a cheap Pentium 4, which would be faster at a lower clock speed. Fry's is probably cleaned out by now, but I picked up a couple of P4 3.2GHz Prescotts for $10 each in retail boxes, and new 945P motherboards for $5 each. :D
