Hi boheme ,
your motherboard will accept
8 x DIMM, Max. 64GB, DDR3 2133(O.C.)/2000(O.C.)/1866/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory
so you can use the 1333mhz kigston you selected but i would use 1600mhz DDR3 from , kingston/corsair/mushkin/crucial/gskill ,
all are quality ram manufacturers with a lifetime warranty
your board will accept quad channel kits 4x4gb or 4x8gb and you can install two sets giving you 8 sticks of ram
the amount of ram you wish to use is dependant on your needs
go for kits with a cas latency of 9 or lower
