I have the Aspire 5750 Laptop which came with 4GB (2 x 2GB Sticks)
I decided to upgrade and bought 1x 8GB stick without checking if it was supported. I presumed it was...
I left one 2GB stick in and replaced the other with the new 8GB. I didn't think it would work as I checked this morning on the interweb and found that each slot only supports 4GB each. This info was from a thread two years old though so I thought that I would try it anyway thinking that the BIOS updates that have been supplied since release may have allowed more memory to be installed. In windows and the BIOS it shows as 12GB total. Now 2 + 8 = 10 so why is it showing 12? If the 8GB stick is not support would it still show in Windows and the BIOS? If so I take it that its not even using any of the 12GB. The laptop doesn't seem any slower like its only using the other 2GB stick. In fact it seems a little quicker but that may be because I replaced the HD too with a 7200rpm instead of the old 5400rpm which started to fail.
Can anyone enlighten me as to what happening and if its using the 8GB or should I send it back and get 2 4GB sticks instead?
