I've managed to understand timings, speed, voltage, capacity etc, there's just two small things that I can't seem to find an answer for.

A little background before I get into the question:
I have 5 sticks of RAM and four slots (I'm recycling some old computers)
Three sticks of Hynix HMT125U6TFR8C-H9 (2GB PC3-10600U)
Two sticks of Hynix HMT325U6BFR8C-H9 (2GB PC3-10600U)
I know the timings will run at 9-9-9 @ 666 MHz, so they will work fine together if I use two of each (so there is two exact pairs) to give me 8.00GB RAM.  That's all fine and good.

The two things I can't seem to figure out are some extra info on the stickers that are on the physical sticks themselves:
1) The first three state "9-10-B0" while the other two state "9-10-A0" and I can't seem to find out what the A0/B0 stand for (Hex? A0=160. B0=176 ??)

2) The first three have an extra number "1105", and the other two have "1113" which I thought at first might be batch numbers, however the first three came from three different computers, and just happened to be the same model.

Any help would be appreciated.

THIS IS A GUESS - Because these are stickers I am thinking they must be manufacture date numbers where the zero is a placeholder for a future letter-- Or maybe the month of manufacture date 10 - October 11 November

 

HEX   Decimal

A-      10          2010??

 

B-      11          2011??
