Okay, so my computer is getting on 8 years old now, but because it was top of the line in its day, it still runs well. Long story short, I'm looking for help and info on upgrading my RDRAM.
Currently, I have a D850EMV2 motherboard
, a Pentium 4 processor
, and 2 sets of paired RDRAM sticks
(all four sticks are 256MB, Kingston ValueRAM model KVR1066X16-8/256
). I've been to Crucial.com and scanned my system and entered the known information, which led me to the info that the max RAM my system can handle is 2GB.
Basically, what I'd like to try to do is just buy 1GB PC800 RDRAM and replace one of the 256MB (1066 MHz) sticks with it, thus giving me approx 1.76GB of RAM total. To the questions of whether I need to install in matching pairs, Crucial says, "No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance." I'm lost on the dual-channel thing. So will my idea work? Or am I going to have to buy 2 x 1GB PC800 sticks or 4 x 512MB PC800 sticks for everything to work right?
Also, I read something about 45ns vs. 40ns
internal timing when it comes to RDRAM, but I'm not sure what that refers to and can't find a reference to it on my current RDRAM or the RDRAM I'm thinking about purchasing.EDIT:
Just came across this link
. It offers info on compatibility, and it appears that I have to install RAM in pairs,
but I'm still a bit confused. Could I install two 512MB sticks and keep two of my 256MB sticks? Given similar prices for 512MB and 1GB, wouldn't it be best to get two 1GB sticks? (RDRAM is expensive!) If I do go with two 1GB sticks, would I install them one in each set of slots (|X - |X), or both in one set of slots (|| - XX), where | represents a RAM stick and X represents a continuity placeholder? I'm not even sure I still have my RAM module continuity placeholders, though.
In addition, I don't really understand the 400MHz FSB vs 533MHz
Front Side Bus issue.
Any help with all of this would be much appreciated.
