For a very long time, the computer club I was in operated a DNS server on a Pentium 75MHz and after the last major hardware upgrade it had a total of 110MB RAM memory and 2G disk space. It worked great except that before the upgrade it tended to run out of ram whenever there was a Linux kernel update, a problem we solved forever by populating all the ram slots with the maximum that the motherboard could handle to that nice 110 MB.
Did you populate the motherboard with the most it could handle, or the most you could assemble from a box of assorted sticks?
Otherwise, 110MB would hint at a fascinating engineering culture at the motherboard manufacturer.
