Warning W2507 - There are very few memory slots. If some are already filled, to upgrade the memory will mean to discard some of the existing modules that will prove expensive. Try not to buy a mainboard with less than 6 SIMM sockets or 2 DIMM or RIMM sockets.
Fix: You cannot fix this - but keep it in mind when you buy your next mainboard. Buy one with more memory slots and use higher capacity memory modules.
