Corsair 5400C4
Like all other Corsair TwinX modules, the TwinX 5400C4 are sold in a plastic package containing two sticks of XMS2:

Small innovation, a short installation guide is now enclosed and briefly shows how to install these new modules. Likewise, the traditional Corsair case badge is still included. Let’s look at one of the CM2X512-5400C4 sticks now:
In short, nothing seems to distinguish the DDR2-667 modules from the DDR2-533 modules apart from the label. It is important to note first that Corsair’s 667MHz modules are available in several types. Firstly, the sticks used in TwinX kits are available individually in the form of standard XMS2 modules. Currently, there are 256MB and 512MB versions, which means there are TwinX kits of 512MB (2*256MB) and 1GB (2*512MB). Another option, for the first time on a DDR2 module is the “PRO” version which exists only in 512MB size and is equipped with activity LEDs as we have already seen in a preceding article.
Concerning the timings, the Corsair DDR2-667 modules are specified with
the same timings as their DDR2-533 predecessors, i.e. 4-4-4-12. On the
other hand, Corsair indicates a voltage of 1.9V for the PC-5400 version
whereas the PC-4300 were rated at 1.8V, the threshold set by JEDEC. Like
all Corsair modules, these sticks carry a lifetime warranty.
- Stability
Before moving on to the benchmarks, we let Memtest 86+ V1.20 run one night at the specifications indicated, i.e. 667 MHz at 4-4-4-12 latencies and at 1.9V. Not a single error was detected, the Corsair memory thus proved exceptionally reliable.
Following Corsair, let’s take a look at the Crucial Ballistix modules:
