Two sticks are better than 1 (almost always!)....a single 8GB stick with same specs operates as a 64bit device in single channel mode, when you take two sticks (2x4GB) and run in dual channel mode the memory controller looks at the sticks as a single mass of DRAM that can be addressed by the equivalent of 2 controllers so each channel operates in conjunction to run the total DRAM in effect as a 128 bit entity
Article is very true, in this case (the question) 2 sticks of 1866/CL9 vs a single 8 GB of 1333 is no contest, unless he somehow found a 1333 stick that runs at CL5/6 which would come close to approximating 1866/CL9 in dual channel performance
Kingston 8GB 1333 DDR3; and
8GB Genesis (1866C9D3K2/8GX) 2x4
and what's the meaning of the code on Kingston Hyper X, '(1866C9D3K2/8GX) 2x4'?
I'm Jewel with Kingston Technical Support. I just wanted to offer our assistance and explain our naming convention. We actually have a decoder for the part numbers here: http://www.kingston.com/us/memory/hyperx/decoder/ . the PN KHX1866C9D3K2/8GX breaks down to this:
KHX = Kingston HyperX
1866 = Frequency
C9 = CAS Latency
D3 = DDR3
K2 = Kit of 2
8G = Total Capacity
X = Intel XMP
If you have any other questions or concerns about our products, please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you. Please be sure to have the part in question on hand when you call.
