dell 8100 ram upgrade

My dad wants to upgrade the memory in his dell dimension 8100 and i cant find any 64mb RDRAM sticks....or is it possible to just buy a 128mb stick and add it on to the existing 2 64mb sticks but i heard that they have to be in pairs. So does anyone know any site that carries 64mb RDRAM sticks?

Try pricewatch.com to find a site that will.

You can get those mock sticks. They arent actually ram but fool the motherboard into thinking its a pair. At least thats from memory.

You need to install the RAM in pairs. (BTW, your machine will already have the blank terminating modules in the two unused slots.) What you need to do is find out whether your father's 8100 is using PC600 or PC800 RDRAM. If the two current sticks are PC600, then buying PC800 is a waste since they will just drop down to PC600 speeds anyway if they are in the machine with two PC600 modules. (A lot of the earlier 8100's shipped with PC600 since PC800 was quite expensive.)

So, if the first two are PC600 use pricewatch to get another two sticks of PC600 RDRAM. If they're PC800, get another two sticks of PC800, since PC800 is faster and you want to match the frontside bus as long as it doesn't cost you too much more.

Just looking quicky, I see 128 MB sticks of PC600 RDRAM for $29 each, and 64 MB sticks of PC800 RDRAM for $28 each. So, if all you need is PC600, you can get more memory for the same $$$.
