TwiSTER PC4000 DDR Memory
by David, 26 July 2003
recent introduction of Intel's new 915/925 series chipsets have
brought along a couple of new technologies, including DDR2 memory.
In recent weeks, DDR2 memory has slowly started to creep onto retail
shelves, though widespread adoption of the new technology is still
considerably far away, in part due to the high cost involved in
transitioning to the new platform as well as availability issues.
As a result, plain
old DDR memory is still very much alive and kicking.
people at TwinMOS sent over a set of their TwinMOS TwiSTER series
memory for our evaluation some time ago. Aimed at gaming enthusiasts
who want high speed memory for their dream machines, the TwiSTER
line has the 'S' standing for 'Speed' while the 'TER' is named for

such, the specifications of the memory modules are exactly the same
as the PC3200 modules specified in TwinMOS's website.

states that these modules run on 2.5V +/- 0.2V. This is a little
odd, seeing as our review units were rated at 2.8V, and wouldnt
operate properly at anything lower than that.
you also notice that TwinMOS has two versions of this memory module:
TSOP and WLCSP packaging. Our review unit features TSOP packaging
memory, which is the standard rectangular shaped memory chips you'll
see on typical memory modules. An example of WLCSP packaged memory
would be the GEIL Golden Dragon series memory.
