Something is slowing down the transfer of data in core memory. Most obvious question is what is the status/size of the CPU cache? Is it disabled in BIOS? Failing that verify the settings of all CPU jumpers - if the board is like most there's a variety of different CPU speeds, clock multipliers, etc. that can be set. This could also be soft configured in the BIOS, it is also possible that a firmware upgrade to BIOS could fix it.
