I'm upgrading an old XP Dell Latitude D620 from 2GB of ram to 3GB.
It can take 4GB but on my 32 bit system it can only see 3.3 GB so I'm just going for the cheap upgrade.
Both slots are now filled with 333 speed ram. The new ram is 667 (only replacement I could find).
The DIMM A is under the keyboard, DIMM B is under a simple to open door on the back of the machine.
Does it matter where I add the new ram? (2GB PC2-5300 DDR2 667Mhz)
