Installation and Setup:

Although the motherboard we used for testing - the ASRock X58 Supercomputer, claims to be able to handle 24GB of DDR3, it's not as simple as plugging in the memory and having everything work properly.  By default the system would only detect 16GB of memory until we enabled the "Flexibility Option" in the BIOS.  When this was enabled we are now able to see all 24GB of memory.

CPU-Z shows the memory information and four possible JEDEC specifications that it can be clocked at.  For this article, we are simply trying out 24GB of memory in the system and left the RAM running at its default 9-9-9-25 at DDR3-1333.  As you can see, it has the ability to run a little faster at CL9 and quite a bit faster at CL10.  The performance you'll gain from the faster clock speed will be negligible though as you decrease the latency.
