I did not realize that the high end UE machines did NOT have ECC cache - this has been pretty much standard practice for 5 years.

Rudedog.... The Sun problem is with external (off chip) L2 SRAM cache.(not main memory) For all Intel CPU's the L2 SRAM is now on chip (even the large L2 Xeons) and is ECC. The UltraSparcII design has large off chip L2 SRAM cache which SUN incorrectly decided did not need to be ECC. This is hard to believe given up to 8MB of L2 SRAM cache for these systems.

FWIW, I did a little searching of the Intel site. This article:

intel.com

suggests to me that ECC cache became available on the Pentium II in mid 1997.
