ASRock Z77 Extreme6—Visual Inspection

With the Extreme6, compared to the Extreme4, there are a significant number of changes, both visual and in terms of features. For a start, the heatsink design is more pronounced, using something similar to their X79 range in terms of black and gold ridged and edged surfaces. The VRM heatsink design is more substantial than the Extreme4, even though online it states it is still only an 8 + 4 VRM design—actually looking at the board, it seems more of a 10 + 4 design.

By looking at the motherboard, you would assume that it would support three-GPU setups. Unfortunately, this third full-length PCIe lane is only PCIe 2.0 x4, rather than splitting up the PCIe 3.0 lanes x8/x4/x4 or using a PLX chip. The MSRP for this board should be around $177, indicating that perhaps that is too cheap a board for one of the expensive PCIe 3.0 expansion PLX chips.

Onboard is also an mSATA port, right in the middle between the first PCIe slot and the PCI slot. Above the PCIe slots is a 4-pin molex power connector to provide extra power to the PCIe slots, although I am kind of getting tired of seeing it put in this location. If anything, it should be at the bottom end or beside the 24-pin power connector, as having it above the PCIe slots just means that there will be cables all over the place.

One other less obvious change to the Extreme4 is that there is a Floppy drive header on board. Yes, you heard me right—floppy drive! It seems odd now to include this legacy connection. It still has a place in industrial concepts (where a machine uses floppy drives and costs 1000x more than the PC processing its data), but not particularly on a higher end product which may be geared towards gaming and overclocking. Perhaps if ASRock are the only ones, then it creates a niche just for them.

In terms of fan headers on board, we have one three-pin beside the 8-pin 12V power connector, two CPU headers (one 4-pin, one 3-pin) just to the right of the top heatsink, two chassis three-pin headers beside the molex connector, and another 4-pin chassis header on the bottom of the board. On the right hand side, the USB 3.0 connector has been placed beneath the 24-pin ATX power connector, followed by the SATA ports. Like the Extreme4, we have the PCH SATA ports (two SATA 6 Gbps and four SATA 3 Gbps) and two extra SATA 6 Gbps from an ASMedia ASM1061 controller.

Around the larger chipset heatsink, we have power/reset buttons and a two digit debug display, both of which I personally like to see as a reviewer (makes my job a bit easier) but also helps overclockers. On the south side of the board, apart from that floppy connector I mentioned, we have a COM port, front panel audio, and an array of USB 2.0 headers.

PCIe layout is similar to the Extreme6, with a PCIe x1, PCIe 3.0 x16/x8, an mSATA connector, PCI, PCIe 3.0 x8, PCI, and a PCI 2.0 x4. This allows a user to use a dual GPU setup, and still have access to a PCIe x1 and x4.

Aside from the bowed picture from ASRock, we have something similar to the Extreme4 for the IO back panel, though this time with a DisplayPort output. From left to right, we have a combination PS/2 port, two USB 3.0 ports (blue), a D-Sub port, DVI-D, DisplayPort, HDMI, a ClearCMOS button, two USB 2.0 (red), an IEEE1394 port, eSATA, gigabit Ethernet, two more USB 3.0 (blue), and audio outputs including an optical SPDIF.

Nothing immediately jumps out from the board features list aside from the differences to the Extreme4. This is a quite good package for an MSRP of $171.

    Indeed. Personally im looking at the Intel DH77DF:
    http://www.intel.com/content/dam/www/public/us/en/...

    I dont see the need for anything bigger than mATX anymore. And for most mITX will do everything and abit more.

    Personally I got a hint from another person. So I will be looking at the DH77DF, 2x8GB, GTX 680 and a i5 3570 and put it into a Silverstone SG08.
  • hybrid2d4x4 - Monday, April 9, 2012 - link

    Agreed. mATX or smaller for me plz!
  • Paapaa125 - Sunday, April 8, 2012 - link

    What is the actual significant difference between Asus P8Z77-V and P8Z77-V Pro? The only things I noticed were a few more phases in power supply (not significant).
  • Byte - Sunday, April 8, 2012 - link

    The only diff I see is the 12 vs 8 power phases, extra USB3.0 header, and pictures look like it includes a usb and esata pcie 1x card.
  • ASUSTechMKT - Monday, April 9, 2012 - link

    Pro offer higher quality back I/O bracing for the display connections,
    High phase count 12+4
    Additional front USB3 front header
    ESATA via bracket
    Additional fan header

    Otherwise all other key features and hardware implementation is the same.

    Given this statement on the first page, why does the chart indicate that the Panther Point chipsets provide 4 USB 3.0 ports?
  • Knifeshade - Sunday, April 8, 2012 - link

    First page, the paragraphs detailing the various features. You spelled Cougar Point in place of where I think you mean to say Panther Point....
  • DesktopMan - Sunday, April 8, 2012 - link

    PCIe / PCI info in the last page table would be appreciated. Good overview. Quite curious to see if the memory stuff from Asus actually does anything.
  • MrSpadge - Sunday, April 8, 2012 - link

    All 6-series chipsets are said to support PCIe 3 in this table. Would that work with Ivi and a proper GPU? Would be the first time I heard about this. And since PCIe 3 is supposed to be a new feature of the 7-series I suppose it's a typo.
  • GreenEnergy - Sunday, April 8, 2012 - link

    Well, alot of 6 series boards supports PCIe 3.0 due to the controller is on the CPU (Ivy Bridge). Essentially the only reason besides BIOS for PCIe 3.0 support on the 6 series, is the added switches for splitting the PCIe x16 into two x8. Thats also why the basic 6 series boards got a bigger chance of PCIe 3.0 support.
