My memory is failing me RIMM 800PC

[szlats]

I have an older Gateway 700X computer with an Intel (Lexington 2) Pentium 4 - 2.4-GHz / 533-MHz mother board. It has 4 256MB RIMM 800 PC memory cards. It has been giving me a number of errors and when I ran Microsoft's memory test the memory failed. I tried re-seating all the cards and then tried removing 2 of the 4 cards but the machine would not boot. I think I need all 4 cards in place to boot up so I'm having problems finding which card is the faulty one by going through a process of elimination. A new card cost $140.00 which is pretty ridiculous for old slow memory but I would like to salvage the machine. I'm told that there is a C-RIMM spacer which can be used to replace a card and still have the machine boot up normally but I can't seem to find a source of supply for one. Any suggestions on a way around my problem, a way to identify which card is bad, or a reasonable source of supply for 256MB RIMM memory?

Yea, when you fill two of the slots, you need to put c-rimm the the other two. They are just blank memory cards, but due to rambus technology, it requires you to complete the circuit. Should cost around 5 bucks each, and you need two.

Thanks. Can I fill 3 of the four slots and use one C-RIMM for the other or does the C-RIMM need to be installed in pairs also? It would be nice to salvage as much of the memory as possible. Also I assume it does not matter which slot(s) the C-RIMM is placed in but correct me if I'm wrong.

It has to be in pairs. So you have to at least have two rimm, and two c-rimm for a running machine.
