What all is in the Model number of GSkill DRAM? 
To explain this I will a model at random - F3-2133C9Q-32GXH which I hope will cover the major points, if anyone has a question on a model # feel free to ask?
We’ll look at a set of Ripjaws X – Model # F3-2133C9Q-32GXH and we’ll break it down to ‘F3’ - ‘2133’ - ‘C9’ - ‘Q’ – ‘32G’ ‘XH’
A) F3 - indicates that this is DDR3 (may also see F2 for DDR2, F1 for DDR
B) 2133 - indicates the rated frequency of the DRAM
C) C9 - This indicates the rated CAS Latency of the stick/set, a lower CAS is indicative of higher performance. Here this appears to be the new indicator, ‘C9’, in older models will show with an ‘L’ as in ‘CL9’, as it appears in the next example.
D) Q - indicates the number of sticks in the set, here Q is for Quad or 4 sticks, also will see ‘S’ for a single stick package, ‘D’ for a dual or 2 stick package, ‘T’ for Tri or a 3 stick package, T2 for a Tri x 2 or 6stick package and Q2 for a Quad x2 or 8 stick package
E) 32G - indicates the total DRAM of the package – alsoshown in older sets as 32GB with the inclusion of the ‘B’ . GSkill sells 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 and 64 GB sets (hope I got them all)
F) XH - indicates the specific model line, in this case ‘XH’ is for Ripjaws X High, and as long as we have Ripjaws X, there is also the XL – Ripjaws X Low, and ‘XM’ Ripjaws X Medium others include RL, RM, RH for the Regular Ripjaws (Low, Medium and High, often tied to the CL where lower CL indicates higher performance), the Ripjaws Z lines use ZL, ZM and ZH (yes, you guessed Low, Medium and High), then there are the Snipers that use SR 1.5 volt, SR1 for 1.35 and SR2 for 1.25, Ares com in AB for Blue and AO for Orange. While these are the primary models there are also earlier models like NT, NS, NQ, HK, PK and others.
G) You might also find a “D” at the end of a model # - this indicates the set comes with 1 or at times 2 cooling fans for the sticks.
edited: the following is info provided in another post that might be useful also - will expand it into a separate info post in the near future:

533 1066 8500
