Subject: New motherboard not detecting all memory
Date: Sun, 30 Jun 2013 10:23:56 +0100 [thread overview]
Message-ID: <51CFF92C.8090404@communistcode.co.uk> (raw)
I recently bought a new AMD FM2 motherboard[1] and coupled it with an
AMD A4 APU. I put 2x2GB sticks of RAM in the board, and the UEFI bios
detects both sticks and reports 4GB. Now, when I boot into a fresh
install of Linux [2] only 1501MB is reported as available.
I was told this may be an ACPI problem, I have updated the motherboard
to the latest BIOS revision which works. Could anyone shed any light on
this, or where I should make a start in helping to debug the problem?
Kind Regards,
Jack.
