My co-worker has a ESPRIMO Edition P2510 with 1GB of ram which needs to be upgraded to 2GB. I purchased the relevent chip and put it in the system however it still only shows 1GB.
Chip A = Existing Chip
Chip B = New Chip
If I put in Chip A, BIOS shows me 1GB
If I put in Chip B, BIOS shows me 1GB
If I put in Chips A+B (in either order), BIOS still shows me 1GB
Therefore both chips work but not together.
Chip A = 1GB DDR2-PC4200
Chip B = 1GB DDR2-PC4200 (Corsair Value Select)
On paper both should work together, any reason why they don't?
Is this a BIOS issue or is there a possible RAM difference?
