CPU Upgrade

Posted on 1999-07-25

I have an IBM Aptiva w/ PII 266 chip and an Intell 440LX chipset.  I've been told it's possible to upgrade to a Celeron 466.  Two questions: 1.  How will the Celeron "Socket 370" come into play?  2.  Is there anything major I need to take into consideration while performing this upgrade (other than checking with IBM for a possible BIOS upgrade)?

If your PII processor is slot 1 you will need an adapter.
Get a Socket 370 to slot one adapter (about $8.00 to $10.00)

The only other things to watch for are the jumper/dip switch settings. You should be able to get these from IBM's web site.

Who told you the MB was upgradable, IBM? The Celeron uses a 100 MHz bus. The 266 a 66 MHz bus. Make absolutely sure before you buy the processor..

I almost forgot, check if your motherboard auto detects the CPU voltage or if there are jumpers. Make sure this setting is correct or you will blow the Celeron.

In response to your MB response, I read an article at and other sites that state the celeron chip has a busspeed of 66MHz and is upgradeable with a LX/ED MB.  Thanks for the advice, every bit helps.

And also, whatever celeron u buying, make sure its is at least 300A or higher because u dn't want the old celerons to run slower than your 266. hehe.  Also, if you want more for the buck, u may also add extra cooling fan and overclock the 300a.  It may give you an extra 150 MHz!  But u must check to see if your motherboard can handle it though.
