EVGA X79 FTW

Overclocking: Asus Rampage IV Extreme Versus EVGA X79 FTW
By

EVGA’s X79 FTW gives users dual gigabit Ethernet controllers for around $20 less than its competitor in today’s article, but makes up the cost difference by dropping other features that Asus offers. As an example, its $100 EVBot handheld overclocking tool probably costs more to produce than Asus’ OC Key, but EVBot must be purchased separately.

EVGA’s I/O panel has twice as many USB 3.0 ports. But all eight of these ports share a single 5 Gb/s PCIe link through a single controller and two four-port hubs.

Also noteworthy on the I/O panel is the connector for the previously-mentioned and separately-sold EVBot overclocking controller.

Unlike its competition, all five of the X79 FTW’s x16-length slots can be used at the same time. The first and fourth long slots are true x16 parents that donate eight of their lanes to the second and fifth when they're populated. The third x16 slot is only wired up to run at x4 data rates, but isn’t tied to any sharing system.

We began to wonder why the middle slot hosted four lanes instead of the available eight, like many less expensive boards include, when we discovered that the unsanctioned Intel SAS controller was enabled in Windows' Device Manager. This controller adapts four of the CPU's PCIe lanes to four SAS or SATA ports on certain unsanctioned motherboard designs. Compatibility isn’t an issue, though, since EVGA doesn’t actually expose the ports on this motherboard. But enabling the Storage Controller Unit makes four of the processor’s 40 PCIe 3.0 lanes disappear.

Other unusual or problematic design decisions include a forward-facing power connector, center/rear-edge front-panel audio connector, a single USB 3.0 connector along the bottom edge, and a 13-pin IEEE-1394b internal header with no external port. Of these, the forward-facing power connector will turn into a wonderful opportunity for clean cable routing if your optical drives don't block off the interface.

Installing a card in the second slot for three-way SLI in x8-x8-x16 mode almost requires that you crush the front-panel audio connector's wires. Moving the cards to avoid this issue forces x16-x4-x8 mode with no clearance for the inflexible USB 3.0 cable end. EVGA’s competitor faces a similar issue in regard to its bottom USB 3.0 header, but adds a second USB 3.0 connector in a more accessible location. This is also not a four-way SLI design, though that configuration might be possible by using at least one single-slot card and a bunch of flexible bridges.

Overclocking-oriented features include two rows of voltage detection points near power, reset, and CLR_CMOS buttons, DIMM and PCIe slot disabling switches, and a three-way CMOS selector switch. One of the CMOS ICs is even replaceable, just in case an enthusiast figures out how to screw up all three chips.

Flexibility is the theme of the X79 FTW’s installation kit, since it includes two round and two flat SATA cables, two styles of four-pin to SATA power adapter cables, and three-way SLI bridges with two different configurations. We were a little confused that a company would bother adding a FireWire 800 controller to a motherboard that had no I/O panel ports for it, and even more confused to find that the included break-out cable supports only FireWire 400.
