Yes. Make sure you use approved memory for the system.

RIMM sockets: four
RIMM capacities: 64-, 128-, 256-, and 512-MB RDRAM

"Annoy the boring."

Message Edited on 11/16/01 01:23PM by Goonboy

I added 128 Mb ages ago (early this year) when the prices were more than twice what they are now.

Several points:

1) Crucial does not sell Rdram

2) Dell sells it at elevated prices

3) It must be installed in equal pairs, i.e., two 64 Mb modules, or two 128 Mb modules (for the truly needy, 256 or 512 Mb).

4) If you have PC-600 Rdram, dump it and replace it with two 128 Mb PC-800 Rdram modules.

5) Check http://www.pricewatch.com for availability and best price

You might want to look insde and see which modules were installed by Dell. My Daughters 8100 came with 128MB but it was with two 64MB sticks. I did not find this until I had ordered a new 128MB to up the mem. to 256.
According to Dell, the memory modules must be installed in matched pairs, so if you have two 64's now you will have to get two more 64's instead of one 128.

Dear Jakers,

Thank you for your reply.
This is the exact the problem I have. When opening the PC I found two 64 RD modules.

I go for two 64 MB modules!
Greatings,

PS : All others thank you for replying.

On my 8100, I had two 64 chips and two other chips that I thought were dummy's (Just to hold the slots) When I went to upgrade, I removed the "dummy's" and installed additional memory (from Dell). But the computer would not boot. When I called Dell, they said the "dummy's" were really accelerator chips and had to stay in their slots. Therefore, I could not add to the original memory, but had to replace them with bigger memory.

As mentioned in the post above, is it true that two of the slots are filled by "accelerators" which can't be removed?
If this were true then total MB could only be 1024 which doesn't sound right to me. Paul

Are you sure the two slots aren't filled with continuity modules as mentioned by Robert Hancock in his Memory Upgrade Notes?

"RDRAM systems require all memory slots without a memory module in them be filled with a "continuity RIMM" which serves to terminate the connector. You take these out when you want to put in a RIMM in that slot. If you remove memory you should put the continuity RIMM back in, or the system might not run properly."

That was my understanding also F C.

Exactly.

Yes, you can upgrade your RAM. The RAM modules you currently have are 64 MB each, but you should find out if they are PC600 or PC 800. In my experience, I made the mistake of not ordering my 8100 with PC800, which is must faster, so I ended up removing the two sticks of PC600 and replacing them with PC800. As mentioned in others' responses, the RAM must be installed in equal pairs-so if you want to upgrade to 256 MB, get two 128 MB, preferably PC800. Note: if you choose to keep the two 64 MB sticks in and they are PC600, _ALL_ RAM you install afterwards will run at this slowest speed while the PC600 is installed! The things you see in the other RAM slots are not actually "dummies" as one response indicated, but are called "continuity modules". These, if fact, may be removed in order to upgrade the RAM but must be kept in until replaced with RAM modules.
