Recommended Memory Congurations
• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
conguration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
• If you install four 1 GB memory modules, the system may only recognize less
than 3GB because the address space is reserved for other critical functions.
This limitation appears on Windows® XP/Vista 32-bit operation system which
does not support Physical Address Extension (PAE).
• If you install Windows® XP/Vista 32-bit operation system, a total memory of
less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips.

5.4 RAID congurations
The motherboard comes with the Intel® ICH9R Southbridge RAID controller that
allows you to congure IDE and Serial ATA hard disk drives as RAID sets.
5.4.1 RAID denitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write
data in parallel, interleaved stacks. Two hard disks perform the same work as a
single drive but at a sustained data transfer rate, double that of a single disk alone,
thus improving data access and storage. Use of two new identical hard disk drives
is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one
drive to a second drive. If one drive fails, the disk array management software
directs all applications to the surviving drive as it contains a complete copy of
the data in the other drive. This RAID conguration provides data protection and
increases fault tolerance to the entire system. Use two new drives or use an
existing drive and a new drive for this setup. The new drive must be of the same
size or larger than the existing drive.
RAID 10 is data striping and data mirroring combined without parity (redundancy
data) having to be calculated and written. With the RAID 10 conguration you get
all the benets of both RAID 0 and RAID 1 congurations. Use four new hard disk
drives or use an existing drive and three new drives for this setup.
RAID 5 stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 conguration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID
5 conguration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems. Use a
minimum of three identical hard disk drives for this setup.
Intel® Matrix Storage. The Intel® Matrix Storage technology supported by the
ICH9R chip allows you to create a RAID 0, RAID 1, RAID 5, and RAID 10 function
to improve both system performance and data safety. You can also combine two
RAID sets to get higher performance, capacity, or fault tolerance provided by the
difference RAID function. For example, RAID 0 and RAID 1 set can be created by
using only two identical hard disk drives.
If you want to boot the system from a hard disk drive included in a created RAID
set, copy rst the RAID driver from the support DVD to a oppy disk/USB device
before you install an operating system to the selected hard disk drive. Refer to
section 5.5 Creating a RAID driver disk for details.

ROG Maximus Formula (Special Edition) / Maximus Formula 5-35
5.4.3 Intel® RAID congurations
This motherboard supports RAID 0, RAID 1, RAID 5, RAID 10 (0+1) and Intel®
Matrix Storage congurations for Serial ATA hard disks drives through the Intel®
ICH9R Southbridge chip.
Setting the RAID item in BIOS
You must set the RAID item in the BIOS Setup before you can create a RAID
set(s). To do this:
1. Enter the BIOS Setup during POST.
2. Go to the Main Menu, select SATA Conguration, then press <Enter>.
3. Select the item Congure SATA as, then press <Enter> to display the
conguration options.
4. Select [RAID] from the Congure SATA as item options, then press <Enter>.
5. Save your changes, then exit the BIOS Setup.
Refer to the system or the motherboard user guide for details on entering and
navigating through the BIOS Setup.
5.4.2 Installing Serial ATA hard disks
The motherboard supports Serial ATA hard disk drives. For optimal performance,
install identical drives of the same model and capacity when creating a disk array.
To install the SATA hard disks for a RAID conguration:
1. Install the SATA hard disks into the drive bays.
2. Connect the SATA signal cables.
