Geil Black Dragon PC3 12800 CAS 9 6GB Review



To find out just how well a product performs, you have to test it in a real world environment so that you don't just blindly believe what the manufacturer says the product will do. Some are right on the money, while others fall somewhat short. On the other hand, there are products that exceed the manufacturer's specifications and will perform at a higher level than what the specifications lead you to believe. To find out what kind of performance the Geil modules deliver, I will be running them through the OverclockersClub suite of benchmarks to see how the performance compares to that of modules that are rated both lower and higher than the rated speed and timings of 9-9-9-27. The CPU is run at the default clock speed of 133 x 20 and the memory multiplier is increased to reach the rated speed of each set of modules. For the overclocking test, I will increase the bclock on the CPU to increase the clock speed of the Geil modules.

Testing Setup:

Comparison Modules:

CPU-Z: This application shows us the settings that we have chosen in the BIOS. Items shown in this application include CPU speed and bus settings, motherboard manufacturer, BIOS revisions, memory timings, and SPD chip information.






Task Manager: We use this utility to show physical memory, kernel memory, page file, and processor usage.



Overclocked settings:

  • Processor: Intel Core i7 920 167x20 = 3340MHz
  • Memory: Geil Black Dragon PC3 12800 9-9-9-28 2000MHz

The Geil Black Dragon PC3 12800 CAS 9 6GB kit of memory does not have any heatspreaders on them.  At first glimpse this would give you the impression that they are not going to be able to overclock very well at all.  This is not the case with this particular set of memory. As I begun overclocking the memory modules, I needed to bump the base clock of the i7 up a little bit to raise the operating frequency of the memory. I was able to raise the base clock of the processor all the way up to 167MHz, which allowed the memory to achieve 2000MHz, which is a 400MHz overclock. Now to achieve this, I did need to raise a few of the voltages. The memory voltages needed to be raised to 1.72v to keep them operating stable, QPI volts up to 1.44v and the IOH up to 1.22v. I could have tried to get the memory's frequency higher, however this would have required me to change to CAS 10, which in turn would have been quite counter productive.


The benchmarks used in this review include the following:


  • CPU-Z Version 1.52
