Asus Rolls Out P9X79-E WS LGA2011 Motherboard

Asus has launched its new P9X79-E WS motherboard. This motherboard features the LGA2011 socket and has support for both Ivy Bridge-E CPUs and Xeon Ivy Bridge-EP CPUs. The motherboard features the X79 chipset. This motherboard has a very broad and complete feature set.

The motherboard has support for up to 64 GB of DDR3-2133 ECC memory split through eight memory slots. This allows for quad-channel memory support. Beyond that, the motherboard has a total of seven PCIe x16 slots, allowing for four-way SLI or CrossFireX. The CPU is fed its power through a 10-phase VRM design, which is fueled by a single 8-pin EPS connector. The memory has its own 2+2 VRM power circuitry. The motherboard also has plenty of storage connectivity; it features six SATA3 ports and four SATA2 ports, as well as another two eSATA3 ports. 

External connectivity is taken care of by a legacy PS/2 connector, two eSATA ports, two Gigabit Ethernet ports, two USB 3.0 ports, 10 USB 2.0 ports, a USB BIOS flashback button, 7.1 channel HD audio, as well as an optical TOSLINK port. Internally, the motherboard also has two USB 3.0 ports through a header.

The Asus P9X79-E WS motherboard is already available at select retailers for an MSRP price of $499.99.

    can't wait to compare this one to my rampage iv extreme

    Impressive offering. Gonna stick with my MSI Big Bang II though... when they start making more 16gb DDR3 sticks gonna fill it up with 8 of them and make a crazy RAMdisk.

    X79 really does feel like "2011" these days with 2 native SATA 6Gb/s ports and no native USB 3.0. PCIe 3.0 that "might work"? Crippled chipset? NEXT!
    No Thunderbolt?

    I currently have the normal WS. This new model looks like ASUS' response
    to the Asrock X79 Extreme11, except without adding SAS. It's nice that the
    E improves the multi-GPU support to be 4-way @ x16 each, not so much for
    gaming but for those using CUDA, etc., but a real shame that the 3rd party
    6Gbit ports are still by Marvell because their controller is awful. 2 native Intel
    ports just isn't enough. Does anyone make a decent SATA3 controller besides

    The only thing that annoys me with these boards is the locking mechanism
    for the PCIe slots. With multiple cards installed and a big air cooler, it's kinda
    hard to reach the latch to extract a card.

    Performance-wise though, they're very good.

    As far as I know, the only thing that comes close are LSI SAS controllers. But even then, they are not as good for most applications.

    I have lots of SAS controllers. It depends what you're doing. SAS cards give
    excellent sequential I/O, but 4K random is limited by the card's ASIC, which
    can ruin the potential of multiple SSDs connected to such cards. They make
    more sense when used with Enterprise SAS/SATA for strong sequential, but
    with battery-backed cache to give strong 4K performance aswell (I get 2GB/sec
    on one of my PCIe cards) combined with data reliability in the event of power
    failure. But yes, multiple SSDs in RAID would work better with a bunch of native
    Intel SATA3 ports if only such were available (alas most boards only have two).

    Where you are wrong however is if one is just using a normal single mechanical
    drive. A SAS card with a 600GB 15K SAS leaves any SATA in the dust when it
    comes to general performance, while even just 3 of them will give more than
    700MB/sec sequential.

    The caveat though is that some SAS cards with 6bit SAS support will link at
    only 3Gbit when connected to a SATA3 device. In the case of LSI, one can
    user particular firmware releases to solve this issue for specific cards.
