As RAM is referred to the so-called read-write ...

RAM stores the data only as long as is until the power supply is
interrupted." class="seolink">memory in a PC. This is together
with the CPU at the heart of any computer. RAM is obtained at the time in three
variants. It is divided into DDR RAM, DDRII RAM and DDRIII RAM. Most frequently sought as a spare part of
DDRII RAM, DDR as now is no longer state of the art
and the purchase of DDRIII RAM is often associated with a conversion of
the whole system. DDRII has a socket with 240 pins. Go GDR has only
180 contacts, so that the DRR standard is no longer compatible with
DDRII. Although DDRIII also has 240 pins, but is no longer
backwards compatible with DDRII due to different notches. Thus, in
this generation boards usually remains only the choice of this
either replace or to care for a replacement for the store.
DDR-II-RAM is divided internally depending on the
kind of the chipset. In the smallest
variant, this is DDRII-400. The
chipsets extend to DDRII 1066. This
specification makes a clear statement about the memory clock and the transmission rate. The
clock can be between 200 MHz and 533 MHz. Depending on whether the memory in single-mode or dual-channel is
operated, results in different transmission rates. This can be in a
module between 3.2GB/s and 8.5GB/s. In dual-channel, so if at least
two bars were installed in the system, are the rates,
depending on the type of memory between 6.4GB/s and 17GB/s
In any case, it makes sense to at several bars, each of the same
modules to build in with the same characteristics. Memory is very sturdy, so you may approach on
used DDRII RAM modules. This refurbished DDRII RAM bars are of course subjected to scrutiny,
so that its functionality is guaranteed. Used DDRII RAM is also cheaper than is the case with new.
Is also worth mentioning that there are still systems are produced
that support this standard, which is why the choice often falls on
With refurbished DDRII RAM bars are goods of top manufacturers. Among
them you will find products from Infineon, Hynix, Nanya, Kingston or Samsung. All of these products
deliver outstanding performance. Here it should be ensured that
when several modules have the same bolt to be installed, as they only reach their
full potential and can be there then also assumed that these
modules are compatible.
It is also important to pay attention to whether the RAM suitable for normal PC use, or designed for
servers and workstations. Just about all
computer systems support, for example, no
ECCRAM. This has been specially designed for
server systems and has the property to detect
internal data errors and to correct them instantly, which is why
this type of RAM frequently in computer systems for use in which to tolerate
in any way data errors are as given in servers running in large companies or in
workstations that are used for example in scientific jobs.
The most important information on the respective modules can find
on the label located on the bars.
