I have an Compaq Armada m700. only 64 mb of ram.
I don't know too much about notebooks. I would really like to upgrade it with 128 mb (Dell's having a sale on Kingston Ram). Can anyone tell me if this is compatible?
Compaq's customer support wasn't that helpful.
128MB 16X64 PC100 SDRAM-100MHZ NON ECC SODIMM CL2
Sync DRAM, 144 pin
Yes, that would put you up to 192MB of memory. Your M700 is one of VERY VERY few notebooks that have 64 built in and 2 empty SODIMM slots. Most simply have two slots (with one already filled) and no built in memory. This allows you to spend less than $90 or so and increase your ram up to 320mb! (By just buying two 128mb sodimms).
Anyhow, to answer your question, yes, that specific kingston SODIMM would work fine. It'll put you up to 192mb of memory. If you only want 128, you can simply get a 64mb SODIMM (though that would be a waste of your time and money).
RAM is even more important to notebooks than desktops. This is because of two things:
1. Your battery will last longer with more ram, because you'll use your harddrive less.
2. Notebook harddrives are VERY slow, much slower than desktops. More ram will greatly increase the speed of your notebook.
Generally, for Win98SE and WinME notebooks, I'd recommend a MINIMUM of 192mb. For Win2k, 256mb or more is ideal.
