Upgrading my CPU on my HP Pavilion

Hey guys this is my first time posting here so take it easy on the noob.
I was thinking about upgrading my CPU on my HP Pavilion 533w. Whats the fastest CPU that I can put in there? It currently has a celeron 2 Ghz.

  1. So I guess upgrading from a celeron to a P4 is out of the question. :(
  2. according to hp:

    your pc is socket 478, using the 845GL chipset, which supports 400mhz FSB cpus.

    can't remember if a p4 wth 533 or 800mhz fsb would work in that motherboard. can someone say for sure?
  3. Thanks for all the help guys. :D
  4. some 845 chipsets can support the 533 bus cpu's, while the earlier versions could not. a 2.0 GHz P4 on the 400 mhz fsb would not be a bad upgrade. 2.4 GHz pentium 4s can also can found to use the 400 mhz fsb, but unfortunately they are pretty expensive on Ebay.

    I think Celeron's are socket 478 while P4s are socket 775
    Old Pentium4s are socket 478 also.

    Very, very old P4's are socket 423. Most s423 P4's use RDRAM and they were the fastest thing around in their day.
  7. Yeah i hate to but in but i cant upgrade my 533w hp pavilion from a celeron 2.0ghz to a 2.8 ghz/533mhz p4??
  8. its a asus p4g533-la it has 533 in its name ??? i have 1 gb ram,
  9. If it only supports 400Mhz FSBs then no.
  10. i dont know what it supports getting differ comments.becaue from my school{lincoln technical institute,which im attending for the comptia course for network+,a+,server+,security+...oops got ahead of myself
  11. I am currently building a 533w. The best you can do safely is a 2.5 ghz P4 w/478 soc. I got mine from ebay for like $20. one more thing you can upgrade the RAM to 1 gig or 2X512 DDR PC2100 cards. After that maybe a HDD upgrade.
