ASUS' X99 Launch Includes Rampage V Extreme, X99-A, And X99-Deluxe

ROG Rampage V Extreme

Asus has four X99 motherboards to announce, and for now just three will be available immediately. All four motherboards feature the LGA2011-3 socket, and all of them have support for the new Haswell-E processors. The three productivity-oriented boards are the X99-Deluxe, the X99-Pro, and the X99-A, while the gaming- and overclocking-oriented board is the ROG Rampage V Extreme. No other boards were revealed at this time, although there will surely be more on the way.


The X99-Deluxe has its own distinct feature set, while the X99-Pro and the X99-A are identical to one another, with the exception being that the X99-Pro has wireless AC connectivity. All three motherboards will have eight DDR4 memory slots along with 12-phase VRM circuitry, eight phases of which are for the CPU.


The Crystal Sound 2 takes care of the audio on the trio. Overall, what sets the X99-Deluxe apart is the more expansive connectivity, as it has more USB 3.0 ports, more SATA3 (6 Gb/s) ports, and an additional PCI-Express 3.0 x16 slot. It also has dual gigabit Ethernet. Regarding performance, these three boards should be mostly identical; choosing between them is a matter of figuring out which connectivity options you need and which you can live without in order to keep a bit of cash in your pocket.

The X99-Deluxe also ships with a large number of accessories, including a fan extension card for additional fan headers. There's also a Hyper M.2 x4 adapter, which can be used to install a second M.2 SSD.

Regarding connectivity, the Rampage V Extreme quite resembles the X99-Deluxe, although it's more geared toward gamers and overclockers. It has the SupremeFX audio hardware, along with a more gamer-oriented appearance with its familiar ROG red-and-black color scheme. Included with the unit is the ROG OC Panel, which can be used to monitor and tweak the system clocks in real-time without the need for in-OS software.

The X99-Deluxe is available immediately for $399, while the Rampage V Extreme and the X99-A will be available in September for $499 and $279, respectively. The X99-Pro is expected to hit shelves in October, with no word on pricing yet.

    Don't know with which motherboard(s) you get those two expansion card, but it's a nice little extra to get. Other than that, those motherboards look pretty nice.

    Where is the MATX Board

    If I could afford the X99 Deluxe, it would be in my possession tomorrow. It would look amazing in my NZXT H440 :lol:

    But I can't, sadly, at least for the time being.

    So far the Rampage V Extreme and X99 Deluxe have Asus's proprietary OC socket, which is different from Intel's reference socket. Not sure if all Asus X99 will have this, but here is a video explaining it as well as the difference.

    Are there any details on the extra pin for the OC socket?

    Are there any details about what the extra pins on the OC socket do?

    If there's any consolation, Bleeding Edge Technology doesn't cost just money. There's the inevitable bugs, hair-pulling, teeth-gnashing and the occasional float-tests that First Generations invariably beg. Reviewers are pointing out the number of firmware updates and those delays, and re-waits for fixes-of-fixes.

    I keep thinking some of these look more like a Gen Ludendorff offensive than a product delivery.

    Designed to break performance barriers, ASUS OC Socket utilizes extra pins to connect a proprietary circuit to contacts found on Haswell-E's land grid array (LGA). Combined with our customized UEFI, this exclusive feature enables higher DDR4 memory frequencies, lower latencies and enhanced stability while overclocking, extending all the way to extreme overclocking conditions, such as Liquid Nitrogen (LN2). OC Socket is 100% compatible with new Haswell-E LGA 2011-v3 CPUs, ensuring the ideal combination of overclocking performance and compatibility.
