1.5 System memory
1.5.1 Overview
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched
differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for
better performance with less power consumption.
The gure illustrates the location of the DDR3 DIMM sockets:
Z77-A
Z77-A 240-pin DDR3 DIMM sockets
DIMM_A1
DIMM_A2
DIMM_B1
DIMM_B2
Recommended memory congurations
We recommend that you install the memory modules from the blue slots for better
overclocking ability.
