DIMM and UDIMM

[TrainTrackHack]

You wouldn't want to advise doing this or that to someone new and on a tight budget who is not in a position to simply run out and buy any replacement parts counting on what they have only.

sean2008 did make a positive move when ordering a new pair of dimms and seeing working results there. That's from simply asking for help amd ordering one of the better brands of memory.

You do realise you're contradicting yourself... he ended up simply running out and buying replacement parts anyway, I can't see what practical difference it makes here.

The idea is also not to tell a novice that UDIMM and DIMM doesn't match, because they are different type of modules...

right off you mixed two different types of memory which essentially is a "no no" there. The fact that both work with only one dimm in means both are compatible but not with each other as one cancels the other out.

Whenever adding more memory or replacing memory you first want to match what you already have installed as far as type and generall speed but certainly timings and type to avoid problems. Now you have to choose which you will keep in and add more of that particular type hopefully identical.

If you mix a performance dimm with value ram memory you will automatically see problems. That was one reason why you didn't see any reference to UDimm and Dimm mentioned since the problems was apparently a mismatch of types. I suspected that more then anything right off there.
