upgrading RAM

  teknikz 18:43 23 Nov 2006

a friend of mine thinks that when upgrading RAM, you can do it however. for example....he says that he has 1x 512mb RAM memory, and that he can put 1 x 256mb RAM stick in and it will be fine.

i thought u had to double up on what you already had? who is right?

Depends on both the machine and the type of memory

Very old machines had to have matching ram in the slots. Newer machines could do as he suggested.

I think yu have to match the latest DDR2 memory but I'm sure someone else can confirm this.

Have to agree with Fruit Bat /\0/\ it depends on the motherboard.
Older machines used to insist on it being done in pairs, newer machines do not insist on this unless it uses dual channel memory. If it does then you have to put in the memory in pairs as before. My PC built at Xmas gives the option to use either dual channel memory or normal memory depending on what slots you use.
So I suppose the answer is you're both right depending on the machine.
