Can someone tell me how to determine my batch #?

Settings are:

BCLK 190
Multiplier 20x
CPU voltage: 1.2125
QPI/DRAM voltage: 1.2
DRAM Bus voltage: 1.6
Speedstep and turbo OFF

Running an ocz platinum 6gb 1600 set of RAM at 1520 @ 7-7-7-18 1T timings.

Passed 12 hours of prime95 blend temps capping around 78. Idles in the 38-41 range (sometimes lower). I can take a screenshot if required, although I just closed prime after leaving it on overnight.
