Memory Part Number Breakdown

Recommended Posts

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.
