ECC Support
The Memory Translator Hub enables the use of SDRAM in the DIMM slots
on the PIIISCA/PIIISCD/PIIISCE/370SC3/370SCI/370SCD. The MTH does not
support ECC.
NOTE: ECC type memory may be used but will result in non-ECC operation.
(See page 1-26 for more on the MTH.)
The Memory Controller Hub (MCH) enables the use of RDRAM in the RIMM
slots on the PIIISCA/PIIISCE. This hub supports both ECC and non-ECC
type memory. Check the Memory ECC Mode BIOS setting on page 4-11 to
enable the use of ECC. (See page 1-26 for more on the MCH.)
