Patriot DDR2-1150/PC2-9200 2 GB Memory Kit Review

Patriot PDC22G9200ELK Memory Kit

In Figure 1, you can see the package for this PC2-9200 2 GB memory kit and in Figure 2 the two DDR2-1150 1 GB memory modules. Patriot also offers this kit with 1 GB version, using two 512 MB modules.

Patriot guarantees that these memory modules can run up to 1,150 MHz maintaining 5-5-5-12 timings, which is ok for this clock grade, as these are the same timings used by DDR2-1066 modules we’ve seen from Corsair and Patriot.

These modules use the famous D-revision Micron chips. There are several different versions of this chip around, and the one used on these modules is D9GKX. The part number for this memory chip is MT47H64M8B6-25E and it is officially rated as DDR2-800. Patriot could label them as DDR2-1150 through a process of testing: some chips from a batch can work fine above their specs, so it is just a matter of selecting the chips that can work fine at 1,150 MHz. Inside a batch there may be not so many chips that can work at this clock rate, so that is why Patriot has to charge more for these memory modules.

Since each chip can store 512 Mbits of information, 16 chips are used on an 1 GB memory module (512 Mbits x 16 / 8 = 1 GB).
