Judging from what I've found online, Computocx has recently upgraded the heatsink on the CEC line of memory to the same type they use on their ultra high-end Diablo models. This was largely in response to the many suggestions from European tech-site that had many favorable things to say about Computocx's DDR2-800 memories. They just wanted a little more in the aesthetics department.

Compustocx answer is blend of style and substance. A very large and heavy-duty aluminum heatsink which almost completely encases the memory module. Heat transfer is aided by the large slots machined into the top of the heatsink.

Considering the placement of most motherboard memory slots, this is a good thing since there isn't a lot of airflow in that particular spot in a standard ATX system. However, with the development of newer heatsinks by companies such as Cooler Master, a lot of forethought should go into what motherboard, CPU cooler, and memory combination you intent to use. Memory with a heatsink as large as this won't fit with their new V10 style CPU cooler.

Test System

After getting the modules acquainted into the test platform, it's time to run a few tests. As usual, a few BIOS settings had to be manipulated to get the system to POST and boot with the CEC modules running at 1066 Mhz. Along the way in testing, we'll have to shift the CPU multiplier and the memory dividers to ensure any instability is caused by the memory and not the CPU.

SiSoftware's Sandra will be used to gain synthetic benchmark data from the system's Integer and Floating point bandwidth. We'll also use this section to relay what failed at boot time and what crashed during benchmarking and stability testing.

3600 Mhz CPU Speed

3717 Mhz CPU Speed

3638 Mhz CPU Speed

3638 Mhz CPU Speed

The end of the line came when I tried to ramp up the memory speed to anything beyond 570Mhz. No amount of north bridge voltage or vDIMM would stabilize the system enough to complete a benchmark routine, let alone a Prime run.
