ASUS P7F-X Series 2-15
2.4 System memory
2.4.1 Overview
The 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 figure illustrates the location of the DDR3 DIMM sockets:
2.4.2 Memory Configurations
You may install 1 GB, 2 GB, 4 GB Unbuffered with ECC/Non-ECC DDR3 DIMMs

• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor. DO NOT combine RDIMM and UDIMM.
• The motherboard supports x8 DRAM Only and x4 & x16 DRAM are not
supported
