The way it works, there are 3 memory models. 1gb, 4gb, and 64gb. This is NOT the amount of memory in your machine. 1gb will give you access to upto 900mb but definately not 1024mb if you have 1gb actually installed. For this, you need 4gb. 4gb will give you access to upto about 3072mb of memory. This would be used if you have more than 1gb of memory but not more than 3gb. 64gb will give you access to all of your memory (I do not know the upper limit on this, but I'm almost certain it's not 64gb). This also enabled PAE extensions. I don't know what motherboards support PAE, my original understanding was that only machines that handle more than 4gb of physical memory supported PAE and kernels compiled for PAE would only run on those machines. I was wrong on that. Most recent boards I've dealt with (pIII class and above) work just fine with PAE extensions even though hold less than 1gb of memory. This also enables 64-bit memory addressing (I think that was the term. See the kconfig for the option). Be sure that your replies also go to the list. > 2007/10/24, Wakko Warner <[EMAIL PROTECTED]>: > > > > pgega wrote: > > > > Please do not top post. > > > > > I just installed AMD64 Debian, put 4th RAM stick, but new sysytem does > > > not see the memory, even if I set mem=3900M in grub. > > > > > > I completly do not know what to do now. > > > > I'm using i386 debian with a custom kernel.
