READ the material jaeger66 posted above first! If you understand it then continue.

Download the latest manual for your board here

Open up that PDF manual and go to the page that lists supported clock frequencies and multipliers. If your lucky then your CPU will not be multiplier locked and you can experiment by adjusting the jumpers on the board until you achieve a faster stable speed. Its not as complicated as it sounds. Just pop open your case, ground yourself and then change jumpers. First I would change the mulitplier to 4 to determine if you processor is unlocked, if you computer still registers the CPU as a P2 233 on start up you must resort to FSB overclocking. Depending on the quality of your RAM and your PCI cards (along with the ability of your CPU) you should start to adjust the FSB up in the increments provided by the jumpers checking for stability each time you change them (eg. boot up your PC and play a graphicly intense game or simply run a program that achieves 100% CPU usage (eg. RC5 or SETI@home)

You should soon find out that either your CPU, Video card, RAM, or Hard drive, will fail at a certain level. After this occurs simply choose the highest level you could achieve with complete stability.

*Note* You may not achieve much if your multiplier is locked. A FSB of 75mhz is reasonable and would give you a CPU speed of 262.5.

Also see this. Remember that with a PII 233 you may be able to adjust both the CPU multiplier and the system bus speed, unlike later PII's and PIII's.

Be sure to get the latest BIOS upgrade for your board, if available, at the Shuttle site.

I had a p2 266 and was able to adjust the multiplier on it as well as a p2 333. That is the way to go so you will not throw off your other components. That all takes into account that yours is unlocked as well

I just recently worked on a p2-233 system and instead of trying to over clock it just spent the $80 and put a celeron 533 and a slotket in it. The owner was blown away at the difference.

didn't know there were multiplier-"locked" PII-233 chips. Guess I've been lucky. Have done it with several p-ii-233 chips, and never had a lick of trouble. Rock solid at 300 every time.

building dirt cheap pII-233 systems for family and friends is a really easy thing to do. The links above give more than enough info to do the job. I've been upgrading my family and friends p-I and 486 machines with PII-233-based machines for about $120 bucks from parts purchased on major web auction sites (100mhz fsb motherboard, PII chip, 8 meg agp card, 32 or 64 megs of sdram). I'll invariably use the person's old hard drive.

The person is blown away by the performance and they've got a system upon which they can continue to build. While this system is obsolite, it is satisfactory for web browsing and productivity applications.

These systems consistently provide 300mhz; which ain't bad for a chip now selling for $35 on major web auction sites.

however, recently, the cost of the used pII 350 chips has fallen and maybe now that seems to be the sweet spot in building these low-end pII-type systems. Whaddaya think?

(Just found this board recently. I'm a complete novice at building systems, for the most part. You guys are amazing. Thanks for info)
