can someone help with a memory problem i have a kingston 256 pc2100 in my computer and something else which is 256 making 512 if i want to upgrade the memory in my computer will this make a difference to the speed if i goto 1gb and say use the pc2700 memory instead or should i just use pc2100 and 1 gb my motherboard does support this size memory up to 2 gb i think :THANKS:
It Depends

Mate, it depends on your motherboard. Usually though on DDR memory its backward compatible so it will just run at the slowest speed e.g. 2100. You could go to and from there run the scan my PC - this will tell you exactly what you can and can't fit & mix etc - this is a free service. I've bought from Crucial and they have been excellent.

Hope this helps,
Cheers Keith.
DDR Ram doesn't have the problems of old Ram, you can mix sizes and speed as long as they are DDR (not DDR2) you should be fine.
The memory will clock down to work at the speed of the lowest.
