DDR2 Features Optimize
Server Performance
Server Performance
The need for increased server performance is
unrelenting, thus DDR2 SDRAM is now the
high-density standard for server main memory.
Its advanced architecture gives DDR2 a host of
advantages over earlier standards, such as faster
speeds, better signal integrity, lower power
consumption and better thermal characteristics.
With the industry’s broadest product selection,
Samsung offers DDR2 as registered, parity-regis-
tered, very-low-profile-registered and fully buffered
modules in densities up to 8GB and in a range of
speeds and configurations to support the needs of
performance-conscious users.

Many of DDR2’s key features are optimal for
servers. For example, DDR2’s higher-density
memory capabilities ce higher peak bandwidth and
support twice the data transfer rate of DDR333.
Another DDR2 advantage is increased memory
support because FBDIMMs allow up to eight
modules per channel compared to three with DDR.
In addition, the lower power consumption and
reduced heat of DDR2 are ideal for blade and rack
servers where air flow may be limited.

FB DIMMs for Maximum Density
Samsung Fully Buffered DIMMs (FBDIMMs)
give servers the highest possible memory
give servers the highest possible memory
density and bandwidth. Servers equipped
with FBDIMMs can get up to 64 gigabytes
per channel of total system memory, with the
architecture’s increased number of memory
channels delivering up to 21.2GB/second of
memory bandwidth. In addition, FBDIMMs
deliver exceptional reliability. Most notable is a
silent data error rate of one per 100 years or less,
enabled by a robust CRC scheme that protects
both commands and data. Also boosting reliability
are features such as transient bit-error detection
and retry and “bit-lane fail-over correction.” This
enables the server board to shut down a bad data
path on the fly. Optional bit widths and CRC
coverage are applicable to a wide range of server
applications.

Outstanding Power Advantages
Power usage is rapidly increasing in impor-
tance but servers equipped with high-density
FBDIMMs have strong advantages. For example,
2Gb-based 8GB FBDIMMs provide today’s
most energy-efficient high-density server solu-
tion. Compared to 1Gb-based FBDIMMs, the
higher-density modules make possible server
main memory configurations that require half
the number of DIMMs while achieving the same
overall density. (See chart below.) This is made
possible because four 8GB modules using 2Gb
components consume 47% less power than
eight 1Gb-based modules.

2GB-BASED FBDIMM POWER ADVANTAGE
Samsung’s 2Gb-based FBDIMMs have
significant power advantages, enabling server
configurations that deliver the same power and
voltage as 1Gb-based FBDIMM modules but
consuming 47% less energy because only half
the number of modules are required. In this
case, two different configuration that achieve
32GB of main memory are pictured.
