Kingston memory modules, part number vs revision number

Some Kingston DDR3 DIMMS

Same Kingston Part Number, different Kingston Revision Numbers.

Upgrading memory in some boxes, it turns out that while fairly detailed DMI memory module identification info available through dmidecode on a running Linux system shows a ‘Part Number’ for each memory module:

Handle 0x0015, DMI type 17, 28 bytes
 Memory Device
 Array Handle: 0x000F
 Error Information Handle: Not Provided
 Total Width: 72 bits
 Data Width: 64 bits
 Size: 4096 MB
 Form Factor: DIMM
 Set: None
 Locator: P1-DIMM2A
 Bank Locator: BANK2
 Type: DDR3
 Type Detail: Other
 Speed: 1333 MHz
 Manufacturer: Kingston
 Serial Number: 3C1A27E7
 Asset Tag:
 Part Number: 9965439-121.A00LF
 Rank: Unknown

.. this part number is not always easy to look up, and it is not the same as a Kingston Part Number. On the interwebs, Kingston refers to part numbers like KVR16R11D4/8 or KVR1600D3D4R11S/8G. They have a helpful page about it at www.kingston.com/us/memory/valueram/valueram_decoder that explains what the number means and how to decode it. In Kingston lingo, that is what they mean by ‘Part Number’.

The dmidecode style ‘Part Number’ in Kingston speak, is a ‘Revision Number’. About this they don’t really talk a lot and not all revision numbers are actually mentioned anywhere on the indexed web. You might find them mentioned in data sheets. KingstonĀ  do tell you how to find this revision number, at https://legacy.kingston.com/support/help_master.asp, probably because when there is a reportedĀ  issue, internally at Kingston this pinpoints more exactly what product version it is. A Kingston Revision Number looks something like the above, 9965439-121.A00LF. There is also a third number, called the Work Order. That is not very interesting as far as I can tell.

It might help somebody if I write down some Kingston Revision Numbers I encountered and which Kingston Part Number they map to – if you have the physical module, it shows both. There goes:

Will add more as I come across them.
