Does the missing memory show up in other OSs? It can be faulty ram if it doesn't show up in any OS, recently had that problem.

Hello!
I've installed an x86_64 Arch on a PC with 8 GB, but it seems to be seeing just four. What have I done wrong?
Bios sees 4 x 2GB Modules and reports 8 GB, but top or free report only 4 GB.
Best Regards

You could try running memtest86+ on boot and see if it detects the additional memory.
I never heard that anybody solved this issue, but I read that many people have this issue too.
On my computer there are only 3 GB + 768 MB of 4 MB available. The graphics has got it's own framebuffer, 256 MB, but IIRC I once have seen that the framebuffer is 512 MB. I guess I can see it running NVIDIA settings, but at the moment I can't run it, because I'm using the nv driver. IIRC memtest86+ did always show the complete memory on my machine. I don't care, since it doesn't make a difference if I got 4GB or 3.8GB. However, I read often about this 8GB issue, for different distros. And it where definitive threads about 64-bit architecture, not about 32-bit and PAE issues.

Ralf, if I got right you can't find the buffer memory right? Assuming you got a gpu why don't you disable the buffer on the bios?
It is disabled in the BIOS and in the past there where no issues. I don't know when this issue occurred for the first time, but there where no BIOS updates, just kernel updates. Regards, Ralf
