Four Pentium II's? What chipset does the system use? The only chipset Intel has released so far (AFAIK) that supports 4 processors is the 450GX chipset. In any case, it seems a bit silly to have a large four processor server that can't cache more than 512MB of RAM. The only way it could cache more is if it's a NUMA machine, and has a different pool of RAM for each processor. Care to elaborate on this machine? Model number, specs?
