The results of our test session showed that both Team memory kits performed identically: in all test modes the difference between TXDD2048M1066HC4 and TXDD2048M1200HC5DC never exceeded 5MHz. so on the diagrams summing up the benchmark results we would only like to provide the peak results for the top memory kit. During our test session we found out that there is very little difference between the maximum working frequencies of the testing participants at 2.4V voltage setting in work modes with 3-3-3-8 and 4-4-4-12 timings on Intel P965 and NVIDIA nForce 680i SLI based platforms. Almost in all cases the difference lies within the measuring error allowance. However, when tested on Nvidia based platform with less aggressive timings of 5-5-5-15 both kits have easily gone beyond 1250MHz (which they failed to hit on an Intel platform). The tested memory kits have even reached 1300MHz frequency.
During the tests on a more traditional test platform built around Gigabyte GA-N680SLI-DQ6 mainboard on Nvidia nForce 680i SLI showed that Team Xtreem modules boast excellent overclocking potential at almost any timing settings. With Command Rate set to 2T we obtained the following results: 1300MHz with 5-5-5-15 timings (1240MHz on Intel P965), 1150MHz with 4-4-4-12 timings and 885MHz with 3-3-3-8 timings. With Command Rate set to 1T the absolute results are definitely lower, but they still remain pretty high overall compared against the majority of memory kits available in the today’s market. The results are1040MHz, 975MHz and 820MHz with the corresponding timing settings listed above.
The slightly unusual comparison against the inexpensive Samsung kit was intended to demonstrate the difference between the potential of standard DDR2-667 that is used in the majority of today’s computer systems and the high-end memory modules like the Team group solutions reviewed today. As you can see from the table above, in both standard test modes the timings of the Team Xtreem solutions are much lower than those of the “standard” Samsung modules, and the maximum frequency at 5-5-5-15-2T timings settings is 350MHz higher: 1215MHz by Team Xtreem against 880MHz by Samsung. This is exactly what you are paying extra money for when buying high-end memory kits: this frequency difference.
