So, on Samsung and Hynix chips, after the usual info like 4GB R2x8 PC3-12800 there is a 11-11-A1 or 9-10-B1. Any idea what that means? I'm trying to start selling RAm on eBay, but not sure if i should separate RAM modules by those identifiers (much more work) or not (much easier).I googled around, but couldn't find any information. Any help will be appreciated.
 
Solution
The first number indicates the memory CAS Latency.

Second number indicates revision of SPD data.

Third characters indicate JEDEC reference design used for the memory module.
