Memory issue in Win XP

As it is a question rather than a discussion topic but never the less here are a few ideas.

1 this unit uses Registered RAM so did you buy EEC SDRAM?

Then did you go into the BIOS and just open the page with the RAM on it to see what the Computer is actually showing? As the HP web page didn't say anything about the type of EEC SDRAM that this computer uses you may have brought High Density SDRAM which will not be read correctly by the M'Board generally if it works at all it will only show half of what you actually brought.

The first thing you have to do is find out if the computer is seeing all of the RAM that you have fitted before you even consider worrying about what it is that Windows sees. From your description I would say you have some High Density Ram which is not supported by the M'Board so you will have to take it back to who you brought it from and get some of the older SDRAM if it is available.

As EEC is not a common RAM type it may prove hard to get if at all as low density EEC SDRAM has not been around for a long time now but a few companies may have some try Corsair or Kingston directly to see if they still list it on their current product web pages and then if they do you can ring them directly and ask who the nearest seller to you is. Most likely it will be a "Special Order" so you might have to wait for a bit to get what you want if it is still available. If it is available buy as much as you can as next time you want some it most likely will not be available.

Anyway no matter how it is that you get on lets know what happens.

Windows XP is a 32 bit operating system and therefore can address a maximum of 4GB RAM.

The new version of XP Pro for 64 bit processors will address 128GB of RAM and 16 terabytes of virtual memory. You will need to have an x64 processor (AMD Athlon 64, AMD Opteron, Intel Pentium 4 with EM64T, or Intel Xeon with EM64T) to run XP Pro x64.
