Upgrading Memory

By LisaNJ ·
Installed on my computer are 2 PC100 64MB SDRAM. I have one empty bank. Can I install a PC100 128MB SDRAM? Does the memory size have to be the same also in order for the system to run properly?

No,they can be different sizes.

NOTE: it is good to have the biggest Ram in the first bank (bank 0) and work downwards. ie. second biggest in bank 1 etc..

There are a number of if then else statements involved, but for most instances, it will work to add another 128MB.

The if then elses are;
Does the motherboard support 128MB DIMMs?
What is the maximum memory for the motherboard?

I would install the 128 MB DIMM in the first slot, and the 2 64's in the other slots.

I have seen motherboards that limit the memory in the 3rd slot. Even had one where if the DIMMs in slots 1 and 2 were larger than 32MB slot 3 was disabled!

I have also seen memory that does not work when used with other brand DIMMs.

That said, over 90% of the time, you will not have a problem. Just make sure that the MB supports 128MB and you are not exceeding any memory size limits.

I've done this several times on different systems and haven't had a problem yet. The new SDRAM can be installed individually with no problems. The older EDO RAM and the newer Rambus RAM must be installed in pairs. Except in the case of Rambus, you can just use a special card in place of a second memory card. But they must still be put in pairs.
My advise to you though is to ensure all of the memory you have is from the same manufacturer. Mixing manufacturers can cause some problems, not all of the time, but close enough. Also, put your largest sized "stick" closest to the CPU in slot one.
