Ancient problem. Only afflicts Pentiums under about 200 MHz, and AMD chips with cheap motherboards. There are a variety of problems regarding the 64MB "barrier" and cache. Most notably, old Pentium motherboards couldn't cache memory about 64MB at all, and Linux wouldn't work if you had less than 512K of cache and more than 64MB of RAM. Not a problem on modern chips.
