Asus M4A79T Deluxe
Features and Layout
Four PCIe 2.0 slots and an eSATA port make the M4A79T Deluxe an enthusiast part, but the single Gigabit Ethernet port separates it from other high-end boards.
We’re not going to second-guess Asus’ design decisions, but the reason AMD originally pushed four-slot 790FX motherboard designs was for four-way CrossFireX support. The configuration is possible on the M4A79T Deluxe, but only with single-slot cards such as the Radeon HD 4850 with reference-design cooling.
Electronic switches allow the M4A79T Deluxe to automatically configure its x16-length slots as dual x16, quad x8, or single x16 and dual x8 pathways. A fifth switch for each secondary slot allows it to use alternative pathways when an x1 card is installed.
An internal feature “missing” from the M4A79T Deluxe is any third-party hard drive controller. Asus instead directs one of the chipset’s SATA 3.0 Gb/s ports to I/O-panel eSATA, resulting in five internal ports. Two of the ports face forward, which could be problematic for some older case designs that have a hard drive cage blocking access.
Three of the remaining ports that face outward from the surface are ideally placed for nearly any mid-tower case, but some full-towers will require extra-long SATA cables to reach the upper bays. Any dual-GPU card could cover up these ports in the center black slot, but the blue slots are the proper places for a pair of Radeon HD 4870 X2s. Single-GPU cards typically used in three- and four-card configurations are short enough to prevent conflicts.
Power, fan, Ultra ATA, and USB port interfaces are all in acceptable locations, but a quick look at the bottom rear corner provides reason for a few complaints. Front-panel audio (off-white) and FireWire (red) connectors are far too difficult to reach with cables coming from upper-bay front-panel ports, while the floppy header—usually required only for adding AHCI or RAID drivers during Windows XP installation—is too far away from a standard case’s external 3.5” bay.

The Asus Ai Tweaker menu contains many basic and a few advanced-clock and voltage controls.

EZ Flash 2 allows updating BIOS from non-bootable media, while Asus OC Profile stores custom BIOS settings for future use.
Two CrossFire bridges and a short SATA cable add value to a traditional accessory kit. However, the outdated floppy cable is gone. Good riddance, we say.
