Intel Z77 Panther Point Chipset and Motherboard Preview – ASRock, ASUS, Gigabyte, MSI, ECS and Biostarby Ian Cutress on April 8, 2012 12:00 AM EST
ASRock Z77 Extreme4—Visual Inspection
ASRock are still insistent with bringing the black gold philosophy to its range, as seen here with the Z77 Extreme4 and later with the Z77 Extreme6. The main point you may immediately notice is the size and depth of the heatsinks covering up the power delivery—they are smaller than previous iterations of ASRock boards, and no longer connected via a heatpipe. This is indicative of quite a few boards we are looking at today, due to the low power requirements of the new processors and as a result, the lack of heat produced at stock voltage.
The socket area is relatively clean, especially to the south where we have no large intruding heatsink. The VRM heatsinks however do brush right up against the Intel specifications for the socket area, so you ultimately have only two directions (to the PCIe and towards the memory) in which to play around with big air coolers. The socket area is adorned with five fan headers—three along the top edge of the board and two chassis headers near the top PCIe x1 slot. The other header on board is along the bottom next to the two-digit debug.
The board is actually not a full ATX sized board—from left to right, it measures only 21.8 cm, rather than the standard ATX size of 24.4 cm. As a result this means ASRock do not have to deal with the far right holes in the motherboard for case mounting, and hence why the SATA ports in the bottom right are neatly tucked away. In this corner, we have the six SATA ports from the PCH (two SATA 6 Gbps, four SATA 3 Gbps) and another two from an ASMedia ASM1061 controller (SATA3_A1 is shared with an eSATA port, however). The internal USB 3.0 header is located nearer the 24-pin ATX power connector, perhaps indicating that is for both front case use and rear case use, taking up the space where the first PCIe x1 is.
The chipset heatsink is rather small, compared to Z68 and X79 boards, and is not connected via heatpipe to any other heatsink nearby. On the south side of the board are the standard array of audio and USB headers, along with a fan header and power/reset buttons. It is good also to see the two digit debug on the board as well.
The PCIe layout is indicative of what we will see on many Z77 boards this year, which do not use any form of PCIe lane expansion, such as a PLX chip. In this case, we have an x1, an x16 (x8 on dual card), a gap, a PCI, an x8, another PCI, and another x1. This is some smart thinking, as even with a dual GPU setup there is space for two single width PCIe x1 cards and a PCI card (which contrary to what some people think are still used in reasonable numbers).
Despite the stock image from ASRock looking a little bent on the back panel, we have a typical Z77 arrangement for IO. From left to right, a combination PS/2 port, two USB 3.0 ports (blue), a D-Sub output, a DVI-D output, HDMI, a clear CMOS button, two USB 2.0 ports (black), an eSATA port (red), gigabit Ethernet, two more USB 3.0 ports (blue), and a standard array of audio jacks featuring an optical SPDIF output.

Rather than dump a Realtek NIC/Audio combination on this board, ASRock have gone for a Broadcom NIC. This means either they have struck a deal, or it works a lot better for their ASRock LAN software. ASRock are one of few motherboard manufacturers to state they support HDMI 1.4a on their website specifications as well. As one of the cheaper boards of this roundup, the Z77 Extreme4 actually comes away pretty well in terms of features.
