I recently upgraded the RAM in my Sattelite A665-S6094 laptop to 8GB, and I was cheerfully greeted with frequent memory-related bluescreens and an inability to use the sleep function.
The laptop works perfectly with the original 2x 2Gb modules installed, but problems show up if I add any more.
When trying to wake the computer from sleep, it gets to the login screen and promptly shuts down as if I pulled the power. This crash is not logged in the system anywhere.
While in Windows, I periodically get a stop error classified as "MEMORY_MANAGEMENT" with no apparent direct cause.
These problems only exist when the installed RAM exceeds the original 4GB size.
I am running the most recent BIOS revision; version 2.20.
