|It's difficult to find out which cpus will work in your mboard because it's got a brand name system bios version, there is usually no info in release notes for brand name system bios versions and bios updates about which cpus the bios version recognizes, and brand name system builders do not provide cpu support lists for the mboards.|
However, you can find out which cpus were used in the same mboard on other models made by HP and sold as Compaq or HP models.
There are 4 possible mboards:
Scroll down - PC Boards
Find the part number on your mboard that is the same. It's on a stuck on label that probably also has a bar code on it.
Then go to the top of that page and enter the part number of your mboard, Search.
At the bottom of the search result page, click on
Click Here to see the list of HP Products that Part Number xxxxxxxx is used in.
Click on any computer model in the resulting list.
Click on one of the Product numbers for the model.
You can use any Processor listed in the resulting parts list in your mboard.
Scroll to near the bottom of the list.
If you need the part number of the cpu, go here:
and click on any make of retail mboard and look at the lists of socket 754 mboard models, and find a description of the cpu that matches the description on the HP site - the part number is a blue highlighted active link on the left. Click on the blue highlighted link for more info. The part numbers with BOX in them are for a boxed set - cpu plus cpu fan and heat sink. Yellow highlighted part numbers are might work - best to avoid those.
They do not list mboards used in brand name systems there. Even if you have a mboard model that has the same model number printed on it's surface, the cpu support lists DO NOT apply to brand name system bios versions.
