The information I've 'sort of' found on 9905403-174.A00LF seems to indicated that the RAM is seemingly rated to DDR3-1600 9-9-9-27-2N @ 1.65v. What I had 'hoped' to see was an XMP-1600 column which would indicate it's clearly XMP <or> 800 MHz.
Meanwhile, assuming DDR3-1600 9-9-9-27-2N @ 1.65v
Extreme Memory Profile (X.M.P.) -> Disabled
System Memory Multiplier -> 16 ; 100MHz * 16 = 1600MHz
/Memory Frequency (Mhz) 1600 MHz ; double check read-only/
DRAM Timing Selectable (SPD) -> Quick
CAS Latency Time -> 9
tRCD -> 9
tRP -> 9
tRAS -> 27
Command Rate (CMD) -> 2
QPI/Vtt Voltage -> Auto ; if you have problems 1.125v
DRAM Voltage -> 1.58 ; if you have problems 1.60v~1.64v
Save & Exit = Yes
Problem the research I've found seems to indicate the RAM is 1.65v and the Rated Frequency is in question. IMO - contact Kingston with that Part Number '9905403-174.A00LF' and have them verify: 1. Rated Frequency and 2. Rated Voltage (1.50v or 1.65v) for DDR3-1600.
Sandy Bridge can run 1.65v RAM BUT 1.50v RAM is highly recommended for the SB IMC, 1.58v is the 'rated' maximum per Intel. Yes, 1.65v has not proven to damage the SB CPU but I'll never recommend ANY DDR3-1600 @ 1.65v.
Next, create a bootable CD/DVD of Memtest86+, use the ISO/zip file. Boot off Memtest and run 2~4 passes; note 8GB takes a long period of time. IF you have any errors then DRAM Voltage -> 1.64v and test again.
