Can I upgrade this CPU

I have an old Sony Vaio PCV-RX550 with a 1.50 GHz Pentium 4 processor (845 Intel Chipset). My son uses the computer and I would like to upgrade the CPU if possible. Could I buy a socket 478 processor to upgrade the computer.

Basically I don't know the current socket type.

Any help would be appreciated.

  1. Without knowing any spec on the power supply, motherboard - you may be able to put up to a 2.0ghz P4 - since that was the last p4 that used the 400mhz FSB. Depending on fast of a p4 you want to put in there - OEMs go from $20-$40.

    Also, depending on what your son uses it for a memory and video card upgrade would show some extra performance. RDRAM is, unfortunately, not cheap and will run you about $50~ for 256mb and $90~ for 512mb. If you never upgraded your video card (the original is a Geforce TNT2) which is ancient by todays standards, your computer has an AGP slot and theres a lot of cards out there that can up your performance - don't go too high end because you'd most likely need to upgrade you power supply which is just kind of throwing more money away (look for maybe a Geforce 4 ti4600 on ebay for like $30)
  2. Thanks for the feedback. He does some light gaming and he has a Geforce FX5200 installed. I also upgraded the RAM a while back and it is max'ed out at 512MB.

    In looking at the following link, it appears that there are CPU's that have clockspeeds >2.0 with 400FSB. Would it be possible to use one of those processors or have are there additional considerations.

  3. I'm guessing it's a 423 socket, though not sure.

    Try using CPUZ:

    CPU-Z

    It will give you more info on your CPU/MB/Ram as well as its settings.

    I'm thinking it might be a wee bit too old to really invest upgrading it.

    Edit:

    But I see there are 423 CPUs for sale on ebay.
