Subject: Intel-Quad on GA-P35-S3 motherboard with 4*2GB
Date: Fri, 14 Sep 2007 10:50:24 +0200 [thread overview]
Message-ID: <46EA4B50.7040904@dgt.com.pl> (raw)
I can't see whole 8GB of ram.
With F2 BIOS release i can only work with kernel param mem=4G.
After updating to F4 BIOS release I can work with mem=8G, but I see this:
# free -m
total used free shared buffers cached
Mem: 6473 474 5999 0 29 278
Without mem=8G kernel starts to slow down and hangs while starting
filesystem.
There is no message.
My whole memory was tested with memtest. Full test took about 48hour. Is
it wrong?
I have: Intel(R) Core(TM)2 Quad CPU @ 2.40GHz
There are 4 * 2GB / 667MHz DIMMs.

I can see that higer memory range was remmaped,
by why accesing something greater than 100000000 is problematic?
Do I need to change something i kernel configuration?
