now do i go for a cheaper option from amazon, they range between £22, £40, also do i get 1, or 2 of them. or is 2 being greedy.
OK dee, so you have 2 memory slots in total on your Desktop & one of them has a 256 stick.
If you do buy one new stick of RAM, you can get an even better result if you place the new(1GB) stick into the first slot (currently populated by your 256MB stick) nearest the processor by removing you existing(256) stick & moving it to slot 2 (currently the empty slot).
The way a computer reads memory is this,
It will read the stick nearest the processor first & if more is required to carry out a particular process it will call from banks 2, 3 & so on. If you have the higher value stick in the first it is more likely to be able to process without having to call in bank 2 & 3 unless you are doing something really demanding. That in itself will add to your performance improvement.
So if you were to buy one new 1GB stick you would put it were your existing stick is & put you existing 256 stick into the currently empty slot to maximize performance.
If you decide to buy two new 1GB sticks? the order won't matter because you will be using two sticks of the same value in both slots.
While running XP, a 1GB plus a 256MB of RAM is quite good & would more than likely be good enough for your needs.
However, you can never have too much memory, so the more the merrier. Either way, if you go from 256 to either 1256 or 2GB the difference is going to be fantastic.
