Chapter 7 FRU/CRU Replacement Procedures 7-7
■ Memory scrubbing: Error correction is performed on data being read from
memory. The correction is then passed to the requestor and at the same time
the error is “scrubbed” (corrected) in main memory. Memory scrubbing
prevents the accumulation of single-bit errors in main memory that would then
become unrecoverable multiple-bit errors.
■ X4 single device data correction (x4 SDDC): When x4 memory is installed, the
ECC function can detect and correct a four-bit error caused by a single failed
memory chip and the system continues to function, though system
performance will be affected. When x8 memory is installed, the ECC function
will detect an eight-bit error caused by a single failed memory chip but will not
be able to correct the error. In this situation a fatal error will be issued.
Caution – Use of unqualified DIMM modules may damage the server and may void
the warranty.
