[SOLVED] No Mem above 3.7GB with fresh install 64-13.1

AlleyTrotter · 01-07-2011, 03:38 PM

I have 4 1GB memory modules in my AMD64 X2, and Slackware 64-13.1 'free' tells me I only have 3.7GB. Never heard of this problem on a 64bit system.

Can you post the output of 'free' ?

Firstly, are you sure that you have not installed Slackware(32), huh? uname -m can help...

Anyway, you should have 3.91 GiB or 4GB on a x86_64 platform.

Secondly, you have an integrated video? The result suspect resembles the case when your BIOS reserves 256M for video, from the main memory.

Yeah, that's probably the answer. I've got 4GB RAM, and integrated video (NVidia 6150SE/nForce 430).

Code:

bash-4.1$ free -m
             total       used       free     shared    buffers     cached
Mem:          3706       1246       2460          0        120        650

Swap:          996          0        996

Yeah, but not probably. That's the answer.

Definitely, absolutely!

Yes thanks all I do have onboard video (GeForce 6150LE) and bios does reserve ram.
I recently had all the capacitors bulge and pop on my video card and removed it.
Now that you all reminded me that is when I stopped seeing 4GB

john@retired:~$ uname -m

Its great to have someone to fall back on
thanks all
