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.

    It doesn't matter, firewire maxes out at 800Mbps, which the PCI standard can easily handle ht 133 MBps.

    Of course, shared bandwidth is an issue, but reworking designs / buying the PCIe design rises issues of cost and reduces the number of PCIe lanes for other devices that can better use the bandwidth.

    Seeing at the layer that Virtu is running and reading about what it claims to be capable of, is there any reason this could not cure once and for all the micro-stutter associated with multiple video cards?
  • jonyah - Monday, April 9, 2012 - link

    It's good to know my Z68 (asus maximus iv-extreme) still hasn't been bested. I see nothing from any of these boards that beats what I've been running for some time now. Plus i have more usb 3.0 ports (12 to be exact).

    For my own PC, I'm interested in seeing what mATX sized Z77 boards there are. Often they have weird expansion slot combinations or positions. Looking at what Z68 boards are out now, it surprises me how many still have PCI slots. I would've thought they'd be replaced by PCIe 1x's by now.

    Also, anything about UEFI bios implementations? Was the promise of fast booting UEFI bioses ever fulfilled?

    I'm planning on making my next build a mATX one, and would be interested in seeing some reviews of high quality boards with lots of features. The Gigabyte mentioned in this article sadly seems to be a cheaper model.

    "...including 8800 and 2400 series..."

    What, are we back in 2007?

    Oh, wait... AMD 8800 and nVidia 2400, not the other way around...

    Wait, that's not right either. What's the 2400 referring to?
  • Ryan Smith - Tuesday, April 10, 2012 - link

    Radeon HD 2400; AMD's low end series for the HD 2000 generation in 2007.
  • extide - Tuesday, April 10, 2012 - link

    You had it right the first time... That phrase in the article was specifically pointing out the broad range of compatibility of the Lucid solution.
  • extide - Tuesday, April 10, 2012 - link

    The first time as in in 8800 = nVidia, and 2400 = AMD

    I don't know if this helps or you wan to put an update but NewEgg has the boards out and prices on them (I am not sure if they sell it at MSRP or not). Just a thought if you want to update those "TBC" prices.
