The SSH4 memory subsystem consists of a single memory expansion board. This board
supports up to 12 DDR registered ECC SDRAM memory modules. The SSH4 baseboard
implementation in SPSH4 server supports both stacked and unstacked memory modules for up
to 24 GB of system memory.
The SSH4 boardset provides the following features:
•
Three interleaved memory banks.
•
Four 184 pin DIMMS per bank.
•
Banks must be populated in order.
•
Single bit error correction – If a single-bit error is detected, the ECC logic generates a new
Qword with a pattern that corresponds to the originally received 8-bit ECC parity code and
returned to the requestor (the processor or the PCI master)
•
Multi Bit error detection – Additional errors within the same Qword constitute a multibit error
which may be unrecoverable. In the case of a multi-bit error, a non-maskable interrupt (NMI)
is issued that instructs the system to shut down to avoid data corruption. ( multibit errors are
very rare ).
•
Memory Scrubbing – Error correction is performed on data being read from memory. The
correction is the passed to the requestor and at the same time is "scrubbed" or corrected in
