Hi I'm sure my problem has cropped up before but I cant seem to fine any mention of it in the archives, so I was running with 256MB of RAM and wanted to upgrade, so I bought a new 512MB stick. The new RAM works fine but when I put the old stick in the adjacent slot the computer does not recognise it. I have swapped them around and run both sticks seperatley, both worl fine but not together. My assumption is that the motherboard is the culprit? I ran SiSoft Sandra and even that said that the second slot was empty. I'm keen but not all that savvy with computers so I'm not sure where to look to see if the slot has been disabled. I went into the setup programme (I followed the simple instructions in the motherboard users guide) but could not anything.
I have the following:
eMachines 190 - Intel Celeron 2.2GHz Micro ATX board - IM845GL (only 2 DIMM sockets) The Ram is DDR PC2100
If so, are they the same BRAND of memory? This can make a difference! Some motherboards will not accept even really good memory if there are odd strips - some will not even use memory of a particular brand! If in any doubt, do not mix!
