Pentium III 450 overlocking

[loudmouth]

I was told that the pentium 3 450 couldn't be overclocked because the multiplier was locked internally. But I've read some posts here and noticed that many are overclocking the Pentium. How are you doing this. Is this Super Slocket any useful http://www.angelfire.com/wy/DellOPTIPLEX/GX1.htm

thanks

Yes the Pentium 3 450MHz most definitely is capable of being overclocked.
While your correct in stating the the multiplier is locked internally, the FSB (Front Side Bus) setting can still be adjusted to whatever settings your motherboard will support.

The link you quoted looks to be basically a generic Slotket such as you could buy anywhere, if you wish to use a FCPGA Coppermine/Celeron processor on a Slot1 motherboard then you could use one of those Slotkets. You have to ensure that your motherboard is compatible with the processor still though.

The first thing to do to go about overclocking is to check what FSB settings your motherboard supports.
Assuming you've never overclocked before I would suggest you let the members here walk you through it before you rashly attempt anything unknowledgeably.

As a side note, the Pentium 3 450MHz processor was actually a decent overclocker. 558MHz was common and even 600MHz wasnt too rare. Of course there is never a guarantee when overclocking.

Well I've checked into your system specifications and more particularly the motherboard.
It seems it auto detects the required FSB setting and does not provide any means for the end user to alter the FSB setting in order to overclock. So unfortunately with this motherboard you cannot overclock the processor.

Your motherboard is however 100% compatible with an Intel Celeron @ up to 533MHz or a Pentium 3 based upon the older Katmai core w/512K L2 cache @ up to 600MHz.
It unfortunately does not provide any support for the newer Coppermine core Celeron processor, or the newer Pentium 3 Coppermine w/256K L2 cache.

It seems in terms of upgrading your processor your best bet would be to upgrade to a 600MHz Pentium 3 based upon the older Katmai core.
I specify Katmai core as it is not compatible with the Coppermine based Pentium 3 which is also available at that clock speed.

Another option which would probably be ideal, is to replace your motherboard altogether. In such a case you could purchase a relatively cheap Slot 1 motherboard that could accept and overclock your current processor and also potentially provide upgradeability all the way up to a 1GHz or faster Pentium 3 processor.
This is the option I would recommend myself as it would provide room to upgrade in the future, and by overclocking your current processor it could last you longer. And as I stated earlier the P3 450MHz is a pretty decent overclocker.

If you wish any further information please feel free to contact me and I will assist you as best I am able. I hope this was of some benefit to you.

I did 558 on by BXII. It burned out after two years with the stock HSFA. Damn shame, but it did good for the price.

awww, you burned one up, shame on u - my 450 is still going strong - yup, one of the first released P3's and built a 4 fan top and tail sandwich combo complete with gap pad(TM) - whopped it straight up to 600 - ran like a chief for 6 months - tis rock solid until i put 2 dimms in - then i have to start dropping the CAS to 3, and to avoid any hassle i chug along at 581 (altho ive had to seriously cool the case after adding the V5500 - couldnt stabilise above 558 with that in, hot little babe it is)

running a PIII 450 right now @ 558 w/Alpha P3125. It was the best Slot 1 (Katmai) for overclocking in my opinion -- it's why i bought it years ago. The only reason i'm not at 600 or above right now is b/c of my vid card.
