The Q67AX Motherboard is compatible with
240-pin DDR3 1066 or DDR3/1333 SDRAM Modules
up to 8GB in size. (Max 32GB system memory)
To gain the performance advantage of Dual channel
communication, use matching pairs of DIMM
modules and populate the slots as follows:
One DIMM module - Plug into socket 1
Two DIMM modules - Plug into socket 1 and 3
Four DIMM modules - Install matching pairs into
sockets 1 & 3, and a matching pair into sockets 2 & 4
