I just built one that used 4 x 4GB chips - Crucial - Part # CT51272BA1339
Works fine with new Xeon E3 1220v2 & S1200BTLR
I must have had a defective board. I sent it back for RMA and replaced it with a different board with a C204 chipset. Using the same components as the S1200BTLR, the new board worked immediately and I have not had any problems.
I will try using the same DIMMs you did on my S1200BTL (not R) when I have time.
