Hi,
I tried this on Fedora 14 and OpenSuse 11.4 and both exhibit the same
behavior. 8GB is installed but only 2698476 shows available for use
using "top" or "free". dmidecode shows 2 4GB DIMMs and the BIOS reports
8GB of memory. Memtest reports and tests 8GB of memory. I Googled the
issue and it seems there are others that also report the same. What to
do? Thank you.
Best,
Chris

Also, do you have the latest BIOS? If not, can you update it? Also, can you try the latest upstream kernel to verify the problem still exists?

Something else you could try is update your Fedora 14 kernel since the latest version supposedly contains a fix which is relevant to your issue: commit 3fdbf004c1706480a7c7fac3c9d836fa6df20d7d Author: Andreas Herrmann <andreas.herrmann3@amd.com> Date: Thu Sep 30 14:32:35 2010 +0200 x86, mtrr: Assume SYS_CFG[Tom2ForceMemTypeWB] exists on all future AMD CPUs -- Regards/Gruss, Boris.

It was already asked for, but dmesg is certainly helpful. Please send the dmesg of a kernel boot. Joerg ^ permalink raw reply [flat|nested] 6+ messages in thread
