DDR2 DIMM
Memory know-how: For the description of speed grades a distinction is drawn between
specifi cations on the single chip (e.g. PC533) or on the whole module (e.g. PC4300).
Specifi cations on the applied chips always refer to the maximum actual clock rate, at which data can
Specifi cations on the applied chips always refer to the maximum actual clock rate, at which data can
be read out of a chip, like e.g. PC133 for 133 MHz for SDRAM. For the specifi cation of DDR modules
applies e.g. 166 MHz x 2, thus PC333. For DDR2 modules x 4, thus e.g. 200 MHz x 4, described as
PC800 or PC2-800.
Specifi cations on the whole DIMM however refer to the data transfer rate which is achieved by the
Specifi cations on the whole DIMM however refer to the data transfer rate which is achieved by the
module (e.g. PC3200 for 3200 MB/s resp. 3,2 GB/s with DDR modules or PC2-4300 respectively 4,3
GB/s). To get this value the actual clock rate (e.g. PC2-800) is taken times 8.

Besides a further enhancement of transfer rates the DDR2 technology
provides an improved electronic architecture of the module as a basis
for higher clock rates.

DDR DIMM
With DDR modules (= Double Data Rate) the data transfer rate is
doubled at a given clock rate compared to conventional SDRAM.

SDRAM DIMM
SDRAM (= Synchronous DRAM) was the basis for the success of DDR
and DDR2 modules. Memory upgrades with these modules are of use
especially for older PCs to expand their memory capacity.
