Old PC133 MHz SDRam question - please help

Hello,

Sorry for the noob-ness, but i did read the faq and searched around for a while before posting this question.

I have a sony PCV RX550 old (P4 1.5GHz, 400MHz FSB) computer (that the kids use and want to upgrade the memory. It currently has 2 sticks of 128 PC133, latency3, non-ecc, non-buffered memory in it and the owners manual says I can only go up to 2x256 for a total of 512. T

My question: Is the density too high to use 2 sticks of 512 non-ecc, non-buffered memory?

Was hoping this was just because 512 sticks weren't cheaply available when it was manufactured but after reading the FAQ, I have doubts about the density. I would really like to get this up to 1Gb of memory if possible.

Yes, I know its a boat anchor for the most part, but don't want to invest in a better machine until the kids are older. (Sorry for rambling)

Thx, Craig

  1. no my friend you cant use more than 512MB ram
    if you can,change your mother board or dont upgrade.
    good luck
  2. It's probably not a density issue but a memory controller issue. It probably wasn't programmed to use ram sticks that large. I have a P3 laptop that had one ram slot, and the chipset only supports 256MB sticks and nothing higher. That means that laptop is forever limited to 256MBs of memory.
  3. got it - thanks to both that responded.
  4. my old pcv-rx650 (the only difference is the 1.6ghz pentium 4 I think), I installed 1GB memory with 512mb each, and I had no problems...this was about 6-7 years ago
    I also put in a NVIDIA GeForce FX5200 128MB AGP card around the same time :)
