If it works, insert the old RAM into the 2nd slot and see if the problem persists.

Just had another thought, too: you could check what the BIOS reports either by entering the BIOS configuration and going to the system information area, or by inspecting your machines POST output (the diagnostic information that is displayed during boot, sometimes hidden by a splash screen with "Press [something] to show details". cheers wraeth -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iF4EAREIAAYFAlN9ZGAACgkQXcRKerLZ91mfFgD/RljFu05+0ymLJrOs8BRUvTji bk1s4RhOGroibx8GaMkA/2xZjYptJrj7PM+7ebw+2FN0juGKFZQyQ5VrL81yYn0z =eRY0 -END PGP SIGNATURE-

[gentoo-user] Only 4 of 8 GB usable
Hi there! So I installed another 4 GiB RAM into a Gentoo amd64 system that had 4 GiB already. But it still sees only 4 GiB, not 8 GiB: leela ~ # uname -a Linux leela 3.6.11-gentoo #3 SMP Mon Feb 4 15:37:48 CET 2013 x86_64 AMD A6-3500 APU with Radeon(tm) HD Graphics AuthenticAMD GNU/Linux leela ~ # free -m total used free sharedbuffers cached Mem: 3688 3269419 0108 1050 -/+ buffers/cache: 2110 1577 Swap: 2047 54 1993 Huh? Any idea why this is? The BIOS shows the full 8GiB, and lshw finds it. dmidecode shows that 8G should work: leela ~ # dmidecode -t 16 # dmidecode 2.11 SMBIOS 2.7 present. Handle 0x0008, DMI type 16, 23 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 8 GB Error Information Handle: Not Provided Number Of Devices: 2 In case this helps, I uploaded the outputs of dmesg [1], lshw -c memory [2] and full dmidecode output [3]. The dmesg output is somewhat weird though, it has several 'vmalloc: allocation failure: 0 bytes' entries. I suspected those were causing the problem, but I found that I needed to activate CONFIG_KALLSYMS=y, and they are gone. But still only 4 GiB RAM. The system is using an old kernel right now, so I cannot get the current dmesg, sorry for this. Probably related: Since I inserted this 2nd RAM module, wakeup from hibernate-ram does no longer work. Does this ring any bells? I'm out of ideas. Except than pulling out the 4 GB, or trying another mainboard.
