Hi all, I have tried google, friends, and everything else I can think of on this one. I have the following system up and running:

Athlon 750
1 GB PC133 SDRAM
6 GB Maxtor HD
Slackware 9.0

Here is the problem:
I can run and use slackware and all of it's functionality. However, I have 1 GB of physical memory installed as 2 512 MB DIMMs. The memory management and system utils are only registering 64 MB of physical ram. I can't figure out what is going on. THis problem is also persistent with Mandrake 7.0 and the newest RedHat distro.

THanks a lot in advance,
Erik

Update:
I tried using the append="mem=1023m"
in lilo.conf, but that isn't working either. BIOS update maybe?

It could be bad memory or the motherboard can not handle 512 megabytes module in each memory bank. Check the manual if it can. Also you need to recompile the kernel to make 1 gigabytes to take effect. Though LINUX will detect a little over 800 on its default kernel configuration.

Take out the memory and put ones that you know works. Do this when the computer is turn off completely and the power cord is disconnected from the outlet.

Unless you like fireworks.


Also, you can test it with Memtest86.
Memtest86 is a stand-alone memory diagnostic tool.
