ASUS P8Z77-V Pro – Overview

ASUS has a lot to live up to with its Ivy Bridge Pro board.  Both the ASUS P8P67 Pro and ASUS P8Z68-V Pro have been top class sellers in their respective chipsets meaning that ASUS has to deliver.  By just looking at the board, it seems that ASUS is keen to innovate and offer a complete package.

In terms of features, by default ASUS has a setting to give a ‘MultiCore Enhancement’.  In the real world, this means that by default ASUS will overclock your processor to its maximum turbo mode no matter what the CPU load.  For comparison with the 3770K, the CPU should be at 39x during single and dual core mode, 38x when using three cores, and 37x under full load.  Using MultiCore Enhancement, you get 39x on all cores no matter what the load.  Therefore, in our multithreaded benchmark suite, ASUS has a 200 MHz advantage per core over other products that do not enable this feature by default.

This is obviously on top of the large assortment of features ASUS already provides.  The AI Suite software is bolstered by a revised version of Fan Xpert, which can test each fan individually for RPM and allows greater fan configuration.  USB 3.0 Boost implements the USB-attached SCSI Protocol on USB 3.0 ports (both Intel [in Windows 8] and ASMedia) to allow greater read-write speeds, especially under high queue depths (if that happens to be your usage scenario).  ASUS also plan for the future in giving a Thunderbolt header for use with their Thunderbolt add-in card due for a separate release soon.

I found one issue with the design of the board, relating to CPU coolers.  The cooler I use for these reviews is the Intel All-In-One liquid cooler, which uses a standard backplate for multiple sockets.  However, with the ASUS Pro, there were placement issues of this backplate due to onboard components:

In order to get the backplate on, I had to bend this pin.  This is generally not advised, but it is a shame that this was not caught when the board was designed.  It seems that perhaps this board should be paired best with a pushpin cooler to avoid this issue, or something a little newer than my solution.  On a more positive note, the board comes with a WiFi module and antennae, which bolt in to the IO panel, and uses an Intel network controller.  For audio outputs, we have the full spread of analog and digital that Ivy Bridge can provide.

Visual Inspection

The ASUS P8Z77-V Pro sports a blue and black livery synonymous with their channel / non-ROG products.  The VRM heatsinks cover a lot of surface area in their jagged fashion, and around the socket itself, we have access to five main fan headers.  Two of these are CPU 4-pin headers just north of the top VRM heatsink, one 4-pin below the left hand side VRM heatsink, and two 4-pin headers below the 24-pin ATX power connector, along with a USB 3.0 port.  A sixth fan header (4-pin) is found on the south side of the board.  All the fan headers are controllable from the BIOS and in the OS, plus the chassis headers offer 3-pin support.

Above the 24-pin ATX power connector, we find the ASUS MemOK! button, which allows memory recovery to default speeds.  Along with the ASRock boards, we have eight SATA ports – four SATA 3 Gbps from the PCH and four SATA 6 Gbps – two from the PCH and two more from an ASMedia controller.  Below this are the TPU and EPU switches, designed for enhanced CPU performance and energy saving modes respectively.

Along the bottom of the board is the standard array of a front panel audio header, another USB 3.0 header, USB 2.0 headers, and a front panel header.  It is also worth noting the Thunderbolt header on the bottom right of the board for that add-in card, and the BIOS Flashback button which allows a user to flash a new BIOS without memory, CPU or VGA required.  In terms of PCIe layout, despite there being three full-length PCIe connectors on board, we are only limited to using two for multi-GPU setups.  In order, we have a PCIe x1, a PCIe 3.0 x16 (x8 in dual GPU), x1, PCI, PCIe 3.0 x8, PCI, and a PCIe 2.0 x4.  Thus in dual GPU mode we can also add in a PCIe x1 and PCIe x4 card.

The chipset heatsink is indicative of the large but low philosophy of many motherboard manufacturers, hiding away the chipset controller.  What is not on these boards, as you may notice, is a combination power/reset pair of buttons, nor a two-digit debug, some of which we used to see on ASUS Pro boards of old.   However, ASUS do have Q-LED, a series of lights on board to show when different stages in the POST process are being initialised - useful for diagnosing POST errors.  

On the back panel, we have a combination PS/2 port, two USB 3.0 ports (blue), two USB 2.0 ports (black), an ASUS WiFi GO! Card, optical SPDIF output, HDMI, DisplayPort, D-Sub, DVI-D, gigabit Ethernet, two more USB 3.0 ports in blue, and standard audio headers.

This means that rather than add in a WiFi module on the board, or use up a mini-PCIe slot with wifi, we have a slot in order to add a WiFi module.  This can be in 2.4 GHz or 5 GHz mode, and updateable as WiFi standards change.  This all comes as part of the package, with magnetic wireless antenna to attach to the case.

ASUS is now placing Intel NICs on all their channel motherboards.  This is a result of a significant number of their user base requesting them over the Realtek solutions.  Also to note are a total of six USB 3.0 on board, two on the back panel and four from internal headers.  These USB 3.0 ports can take advantage of the improved UASP USB 3.0 protocol using appropriate hardware and some ASUS software.  As always, we expect ASUS fan control of the six headers to be top notch.  ASUS also include a TB Header for their add-in Thunderbolt card expected for release soon.

    Are Q connectors proprietary of ASUS? I seem to find those only their motherboards. Love them to death.

    Great review. I enjoy these tremendously. Almost makes me go out and upgrade my i5 2500k.

    My MSI P67A-GD55 has the same thing, unfortunately the connector block is too tall and bumps into my second 6950 so I couldn't use it. Reply

    I, too, am a fan of the Q Connector mostly for the front panel connections (power, reset, HDD light). The USB and audio connectors seem to be pretty well standardized at this point, rendering those Q Connectors redundant IMO. This would seem to be a very simple and inexpensive feature for a mobo manufacturer to have (at least for the front panel connector). Reply

    Thank you for including this important benchmark. I hope that every motherboard review going forward will include this.

    The ASRock has the best time but 8 seconds is still too long. I wonder why BIOS developers can't get their act together and initialize hardware in parallel. That would surely speed POST times up tremendously.

    I've been struggling about that issue myself. I mean - it probably was in times of BIOS, but now, with all fancy UEFI is it really that hard? (considering more resources spent on bios/uefi in mobo)

    Altough I'm not big fan of 200$+ motherboards, I would seriously consider buying one if it POST in 2s.
    Even though there are probably POST requirements such as cpu cant be tested before ram or opposite it would be awesome to have really low boot times.
    Sad when even having SSD cant give You instant full boot (not hibernations/sleeps).

    It's one of those small features that are soo awesome (like reset/power buttons, and perhaps, in future : complete per component (ram/disk/SB/NB/coolers) power usage).

    Nevertheless 8seconds is damn nice.

    Does anyone know how enabling AHCI in the UEFI affect post time these days? I'd like to remove the other 7-10 seconds this adds to it. Reply
  • pixelstuff - Monday, May 07, 2012 - link

    How do those Chromebooks shave time off of the POST? Seems like similar techniques could be implemented unless there is a good reason not to. Reply

    Chromebooks use OpenBIOS IIRC. OpenBIOS is Linux Kernel based and boots very fast because it initializes things quicker and it's custom built to the hardware on the board. Personally I wish all the Boards would start using it and toss these BIOS down the hole of history. Reply

    They've got a very stripped down set of hardware to initialize. The more stuff you have on board, the longer it takes. EFI was supposed to fix this by allowing multi-threaded boot (BIOS was strictly a single threaded design); but either firmware makers aren't generally taking advantage of it yet, or dependencies in the startup process are limiting the gains.

    Don't forget the graphics card (if using discrete) will need to support UEFI (GOP) Booting too! Reply
