We also received two Teamgroup memory kits for the overclocking analysis. The first kit had speeds of DDR2-667 while the second was DDR2-800/1000 with timing differences relative to the frequency the modules are running at.

The memory kits come in relatively simple plastic packaging. The red “X” which covers much of the modules stands for “Xtreem”, which is Teamgroup memory meant for overclocking and overclockers. The heatspreaders used for the modules are not very efficient and have no clamps holding them in place. Instead, they are simply glued to the chip using a sheet of adhesive thermal paste.

In this case, the major difference which allows the modules to reach high overclocks is the Micron D9 memory chip which the modules use. The D9 memory chips are usually power hungry, and so we again reached our maximum voltage limit of 2.45V. For the Teamgroup DDR2-667 the increase in frequency was 69.6% while for the dual-certified DDR2-800 we had an overclock of 15% (DDR2-1000 which is 500MHz) and 43.7% (DDR2-800). In reality, Teamgroup’s default timings are more aggressive at 400MHz (3.4.3) and more relaxed at 500MHz (5.4.4), so for that reason we can say we have a middle value equal to 29.3% for the tests run at timings of 4.4.4.
