ASUS P7F-C Series 2-15

2.4 System memory

2.4.1 Overview

The motherboard comes with six 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 Congurations

You may install 1 GB, 2 GB, 4 GB, 8 GB Registerd, or 1 GB, 2 GB, 4 GB

Unbuffered with ECC/Non-ECC DDR3 DIMMs into the DIMM sockets using the

memory configurations in this section.

• 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
