Onboard RAID controllers provide the motherboard with dual-RAID functionality that allows you to select the best RAID solution using IDE or Serial ATA devices. The NVIDIA NF590-SLI chipset allows RAID 0, RAID 1, RAID 0+1, RAID 5, and JBOD configuration for six SATA 3.0 Gb/s. See pages 2-27 and 5-24. The Silicon Image 3132 controller supports two additional external Serial ATA 3.0 Gb/s ports on the rear panel and allows RAID 0, RAID 1, RAID 0+1, RAID 5 through port multiplier and JBOD configurations on these ports. See pages 2-23 and 531 for details.

ASUS Two-slot thermal design
The motherboard is designed with one PCI slot and one PCIEx4 slot placed between the PCI Express x16 slots, allowing increased airflow between the two PCI Express x16 graphics cards. This special design permits more room for ventilation, thus lowering the overall system temperature.
AI NOS (Non-Delay Overclocking System)
ASUS Non-delay Overclocking System (NOS) is a technology that autodetects the CPU loading and dynamically overclocks the CPU speed only when needed. See page 4-20 for details.

AI NET 2

AI NET 2 is a BIOS-based diagnostic tool that detects and reports Ethernet cable faults and shorts. With this utility, you can easily monitor the condition of the Ethernet cable(s) connected to the Marvell LAN (RJ-45) port. During the bootup process, AI NET 2 immediately diagnoses the LAN cable and reports shorts and faults up to 100 meters at 1 meter accuracy. See pages 4-23 and 5-11 for details.

Extreme Tweaker

This feature allows you to fine tune the CPU/memory voltage and gradually increase the memory Front Side Bus (FSB) and PCI Express frequency at 1MHz increment to achieve maximum system performance.
Optional fan (for water-cooling/passive-cooling only)
The optional fan is specifically designed to provide sufficient airflow over the CPU power modules and chipset area when water-cooling or passive-cooling is utilized, ensuring effective heat dissipation for the entire system. See page 2-11 for details.

System memory

Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket. The figure illustrates the location of the DDR2 DIMM sockets:
DIMM_B1 DIMM_B2 DIMM_A1 DIMM_A2
CROSSHAIR 240-pin DDR DIMM Sockets
Channel Channel A Channel B
Sockets DIMM_A1 and DIMM_A2 DIMM_B1 and DIMM_B2

Memory configurations

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC/non-ECC DDR2 DIMMs into the DIMM sockets.
If you installed Windows XP 32-bit version operating system, we recommend that you install less than 3 GB of total memory. For Windows XP 64-bit version operating system, the maxium support is 8 GB of total memory. For dual-channel configuration, the total size of memory module(s) installed per channel must be the same (DIMM_A1 + DIMM_A2 = DIMM_B1 + DIMM_B2). Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor. Refer to the DDR2 Qualified Vendors List on the next page for details.
