CC Fully Buffered Memory with Chipkill Protection
The x3400 supports up to 32GB of memory in 8 DIMM sockets. It uses PC2-5300 fully-b
data rate II (DDR II) memory (operating at 667MHz) for faster access, and provides advanced Chipkill
memory protection, for up to 16X better error correction than standard ECC memory.
The fully buffered memory in the x3400 provides up to triple the memory bandwidth (up
four channels of PC2-5300 fully-buffered DIMMs vs. a maximum of 6.4GBps in two channels of unbuffere
PC2-3200 memory) and up to double the system memory capacity (8 DIMMs x 4GB) of the pred
x236 server (8 DIMMs x 2GB). By performing reads and writes simultaneously, it eliminates the previous
memory read-to-write blocking latency. In addition, it also offers innovative data reliability and security
features to help improve data integrity, including enhanced CRC protection, data retry on error detect and
buffer registers for improved fault isolation.
For increased availability, the x3400 offers two additiona
Memory protection: online memory mirroring, and online hot-spare memory.
Memory mirroring works much like disk mirroring. The total memory is divided into
written concurrently to both channels. If a DIMM fails in one of the DIMMs in the primary channel, it is
instantly disabled and the mirrored (backup) memory in the other channel becomes active (primary) un
the failing DIMM is replaced. Mirroring can be accomplished with multiples of four DIMMs (one pair per
memory channel).

capacity at least that of the largest active rank. (In other words, if a combination of 2GB and 4GB DIMM
are used in a branch, one rank on each 4GB DIMM will be used for sparing.) In an x3400 with 32GB
installed, up to 24GB (using 8 dual-rank 4GB DIMMs) of memory is available when the hot-spare featur
