You might want to try relaxing the memory timing in the BIOS.  In
particular, try adding some cycles to CAS Latency.  I've had a couple of
systems with ECC RAM that had excessive ECC errors with the default RAM
timing that got much better when I increased CAS Latency.  You might
also want to try rigging an extra fan to blow on the RAM and/or chipset.
