Wired Posted August 25, 2009 Share Posted August 25, 2009 (edited) Here's a quick breakdown of how to decipher the new memory part numbers. Your memory kit uses this notation if they start with CM and then are preceded by a letter. If a number comes after it, then it's a single module using the old notation. Ok, here's how to break it down using this actual part number as an example: CMD8GX3M4A1600C8. Note that CM simply means Corsair Memory, so we'll skip that part. [table=head]Code | (1..2) | #G | X# | M# | (1..2) | # | C# Part # | D | 8G | X3 | M4 | A | 1600 | C8[/table] NOTE: (1..2) means that one or two characters will appear here # means that a number will appear here Here's what each section of the part number means: [table=head]Code | Meaning (1..2) | Module Type #G | Total Part Number Density X# | Memory Tech (DDR1 / DDR2 / DDR3 / DDR4) M# | Module Quantity (Number of Modules) (1..2) | Revision # | Speed (MHz) C# | CAS Latency [/table] So, applying this to the example gets us: [table=head]Part # | Meaning D | Dominator 8G | Kit contains 8 GB of memory X3 | DDR3 M4 | 4 Modules in the kit A | Revision A 1600 | 1600 MHz C8 | CAS Latency 8 [/table] 8 GB / 4 Modules = 2 GB per module In the next post you'll find a more comprehensive breakdown of each section of a memory part number and what they mean.
