X58 To The Max: Three New Flagship LGA 1366 Motherboards

Asus Rampage III Extreme

Quite possibly the best-featured motherboard Asus has ever produced, the Rampage III Extreme is everything its predecessor should have been, and then some.

The “and then some” comes courtesy of an NEC PD720200 USB 3.0 controller that wasn’t available when the first LGA 1366 Republic Of Gamers product was introduced. Retained from previous models is the ROG Connect dual-function USB header that allows tuners BIOS-level access from a second PC, no matter what programs or operating system the Rampage III Extreme is running.

The Rampage III Extreme adds support for four dual-slot graphics cards, a feature that simply must be present before any motherboard can claim to be the “ultimate gaming platform.” Supporting four x16 cards from 32 of the X58 northbridge’s 36 total lanes is accomplished by dropping the first and third x16 slots to eight lanes whenever a card occupies the second and fourth x16-length slots, respectively.

Yet even though 4-way CrossFireX and 3-way SLI are supported, Quad SLI is not (at least out of the box). Nvidia has decided to require two of its NF200 PCI Express bridges to enable the feature, and Asus includes these on workstation-class P6T7 WS SuperComputer motherboard. Competitive overclockers who love the Rampage III Extreme's other features might be interested in its announced ROG Expander, which adds NF200 controllers to the Rampage III Gene through a daughter board. That's going to be a separate purchase though, adding to the cost of this board.

As with most "Republic Of Gamers" products, the Rampage III Extreme's most prolific features are designed exclusively for competition-level overclocking. The Rampage III Extreme lives up to that purpose as well with dual eight-pin CPU power inputs. Gone is the space-consuming and marketing-driven array of 16 tiny voltage regulator phases, replaced by Asus’ Extreme Engine Digi+ collection of eight digital-analog hybrid phases that it claims respond more quickly and accurately while operating more efficiently at high loads. A Q-Reset button next to the CPU’s power connectors allows builders to cut CPU power temporarily to recover from a “cold-bug” boot failure when using sub-ambient cooling.

Buyers now have three ways to access BIOS-level controls from an external device, thanks to Asus’ new RC Bluetooth module. Just as with the previously mentioned ROG Connect, pressing a button transforms the device from an ordinary data link (for mobile device syncing and peripherals) to an overclocking gadget interface. A smart phone becomes the controller for RC Bluetooth, but only if it has Windows Mobile 6.0 Professional (or higher), Symbian 3.1 or 3.2, or Android 2.0. The third method of external control is to borrow an OC Station controller from a previous Asus motherboard that was so equipped and connect it to a special 4x2 pin connector along the Rampage III Extreme’s bottom edge.

The Rampage III Extreme still carries over the top traits of preceding models, such as the ProbeIt voltage-sensor points, the Go Button overclocking profile switch, and a row of PCIe slot-disabling switches to help overclockers determine which card has stopped responding after being pushed too far. An LN2_Mode jumper is meant to reduce “cold-bug” boot errors when using extreme cooling, hopefully reducing reliance on the previously mentioned Q-Reset button.

Asus even includes a button to enable manual switching between the Rampage III Extreme’s two BIOS chips, allowing tuners to boot from one IC and to make adjustments to the settings on the other IC.

The Rampage III Extreme’s remaining layout is almost as pleasing as its expansion slot placement. Six SATA 3Gb/s and two SATA 6Gb/s ports face forward to slip easily under the sinks of long graphics cards and behind the drive cages of most modern cases, while the lack of legacy drive interfaces prevents us from complaining about associated connector placement.

That’s not to say that the lack of legacy connectors makes the Rampage III Extreme’s layout perfect, however. Front-panel audio and FireWire headers are pushed so far towards the back of the bottom edge that they make cable reach a problem for some cases. Another potential problem is that outward-facing headers along the motherboard’s bottom edge require cables ends to be smashed flat when placing a double-slot card in the Rampage III Extreme’s bottom slot and that little issue precludes the use of Asus’ Q-Connector cable-end bundler.

The Rampage III Extreme installation kit differentiates itself from most competitors by including eight SATA cables and a replacement chipset cooling sink with a fan. The original chipset sink can also be replaced with certain chipset water blocks, although buyers should contact the water block’s manufacturer concerning compatibility. Asus includes two-way CrossFire and SLI bridges plus a three-way SLI bridge.

    No EVGA SR-2? :(

    Ok, Hold on. Three Flagship LGA 1366 Boards and no overclocked power consumption results? These boards are obviously made for overclocking and those results would be very interesting to see.

    A good 250$ X58 board is enough for most people.

    The EVGA Classified SR-2 is based on the Intel 5520 chipset and uses Xeons, so it's not an X58 board technically speaking which is why it doesn't qualify. ;)

    If I could spend that much on a motherboard I'd have chosen the Rampage III Extreme, not only does it have good features it also has the best colour scheme. ^^

    Does anyone know why I try to submit a comment it doesn't show up, and I have to use the forums instead to post a comment instead?
  • lashabane
    I want more.
  • sudeshc
    I am totally impressed by ASUS they always come up with best solution in every category, but the price is a killer for me :(
  • rottingsheep
    IMO, the only interesting part about motherboard reviews is the overclocking and power consumption portion.

    Nice article..I have only catch: Of all the mobos tested, Quad SLI is not possible on the ASUS R3E, courtesy of nVIDIA's drivers
  • dragonfang18
    Whats the point when Intel will come out with new processors with different sockets next year?

    Awesome, thanks. Manufacturers don't actually discuss this stuff.

    That's what people like you were saying months before LGA 1156 was released. We see which direction that went.

    Yeah... they are changing 1366 to some socket R... Well... At least I can look forward to these motherboards going down in price by next year when they go to Socket R's for performance than 1366's. I guess ill be happy with 1366's. Hopefully they go down by at least $100.

    2 FPS difference in games. They should have shown what would be the difference if the boards would be OCed.

    What irritates me is the fact that you have a 6+ PCIe 16 board ( with the exception of the ASUS ) and you still cant get full 16 all the way through with out either a bunch of glue chips or "lopping it off" at the legs - 16x/8x ok .. but 16/8/4 ? c'mon .. can someone develop a chipset that will give the USER the option of lopping off legs reassigning resources where needed ? Granted for TRUE quad SLI 72 lanes is desirable (48 is ok in a 16/8/16/8 fashion .. ) but enough is enough .. Intel, nVida, AMD make a chipset that when we plug in .. we get what we want how we want it .. it would mean return customers and money in your pocket and a smile on a system builders face .. (96 lane board should do it ... )

    I think MSI won here not ASUS. More features on less power with cooler temperatures at a negligible performance hit of half a percent that can be attributed to the error with Vantage.

    I don't like any of the motherboards PCI-e layouts. Its a top range board but only assumes to run 2 cards well. Then confuses the user by placing a bunch of half/quarter speed PCI-e slots. X8 on x16 lane is fine, but x4 is not.
  • Emperus
    MSI is the winner in this clearly though i personally would end up getting the R3E.. I've always felt two video cards as the max needed in the real world (never mind the synthetics and folding@home) so on that account, both the MSI and the Asus boards scope a homerun whereas the Gigabyte model may just end up as the company's trojan horse to showcase their engineering strengths at overclock events.. I feel the EVGA 4X SLI classified should've been included in the showdown.. The absence of USB 3.0 and SATA 6Gbps should not be the criteria to leave out such a lovely board (oh! May be the price and absence of crossfire support disqualify it)..

    why get a x58a ud9 and you can get the evga sr2 for less

    mrhoshos96why get a x58a ud9 and you can get the evga sr2 for less

    While the SR2 is nice, I have no need for dual socket. As nice as it would be.

    The only thing the UD9 is missing is three more DIMMs (9 total). I know some server boards have 9 DIMMs per CPU, why not any enthusiast boards?

    I want the UD9, put 12GB RAM in it, two 5870's, a nice sound card and a nice NIC (when going extreme, may as well go the full way right?).
    Too bad I quit my job and can't afford it now. :/

    Can we ever expect 7/8 way SLI/CF drivers? I, for one, would love to use 7 single slot 5770's.

    I'd rather wait for PCI-E 3.0

    what's the use of testing ultra expensive motherboards without the best processor it could fit on it and with a 4 or more array of the most powerfull video cards on earth? this review is like reading the features on the mb's box ... nothing exceptional
  • scook9
    An EVGA board should have been included (and they DO support crossfire)

    Also, no mention was made of the superior Intel Ethernet adapter in the R3E vs the crappy realtek ones in the other boards
  • squallypie
    gosh, why are there no amd chipset mobos :-(! i really want something that compares the chipsets atleast
