Demand for Sandy Bridge paraphernalia will be high—for almost a year now, the question has always been: Shall I upgrade from X to Y? One of the more popular responses, especially as Sandy Bridge has gotten closer, has been "wait until Sandy Bridge is released; it’s just around the corner." Therefore, each motherboard manufacturer will be trying their hardest to get attention by creating the best product line they can—with as many accessories at the lowest possible price. ASRock are, of course, no exception.

At release, ASRock will have several board on offer, ranging from micro-ATX H67 to top-line P67. The Extreme4 is our candidate today, and represents a standard product that people may actually buy when deciding which Sandy Bridge motherboard to get.

Visual Inspection

ASRock have produced a board in blue and black livery featuring a black PCB. The 8+2 phase power design sports additional heat sinks connected via a heatpipe. The socket itself is relatively empty, and ASRock have included mounting holes for socket 775 coolers as well as the socket 1155/1156 coolers. A few people will say this is a bad idea, as it weakens the board, it increases the tracing route length from RAM to CPU, or that some manufacturers will try to put traces between in the mounting holes. I have never had an issue with it, personally.

The SATA connectors are blue for SATA 3 Gb/s and white for SATA 6 Gb/s. Only two of these white connectors are applicable to RAID, so double check before setting this up. The power and reset buttons are located just below this, in usually what is the easiest spot for testing on an open bench, but not always the easiest spot when the board is inside a case. These buttons are also an issue when running dual GPUs with long PCB lengths—to the extent that the reset button is not useable.

Some people may wonder why new chipsets still have a floppy drive connector on the motherboard. The simple reason is that a lot of industrial hardware still calls for it, and it is cheaper to replace a PC than a piece of industrial equipment costing five or six digits. We will not be seeing the floppy drive connector go away in the near future. However, there is no IDE connector on this board.

The chipset cooler is quite small, and large GPUs will rest on it. If the GPU gets quite warm, or likewise the chipset, then these two components will transfer heat quite easily between them, possibly limiting overclocks. Power hungry 4870X2, GTX 480 and GTX 580 users take note! The PCIe slots are laid out ideally here, with a x1 slot at the top, and if all x16 slots are filled a PCI slot is still available. Certain manufacturers fail in their layout slot, but ASRock have used their brains, giving a tri-slot gap between the main GPU PCIe slots.

There are five fan headers on this board, two of them are labelled CPU and three are labelled chassis. Two of the chassis headers are located above the first PCIe x1 slot, right next to each other, and the other is between the 24-pin power connector and the SATA ports. I would have liked at least one of them to be on the bottom of the board—for wide cases that require a fan further down, this would be ideal.


The back panel is standard, with PS/2 connectors, SPDIF outputs, USB 2, USB 3, Firewire, gigabit Ethernet, and the audio panel. As I will state in most reviews, I always prefer dual Ethernet ports, however this motherboard only has one without utilizing a PCI card. One of ASRock’s marketing statements is their XFast USB technology, designed to increase throughput of their USB ports; we've seen it on a number of previous ASRock boards also. In pure synthetics, ASRock claims up to a 97% increase in USB 3.0 writing speed and a 360% increase in USB 2.0. We will test these in the benchmark suite.

    I have the Asrock P67 Extreme4 motherboard and it has serious compatibility issues with USB2 devices.
    Devices such as webcams, USB modems, USB tuners, phones with USB connection doesn't work on the USB 3.0 ports which are built upon the low cost Etron EJ168A chip.

    It is nice that on some storage devices the performance is good, but what about the usability of the USB 3.0 ports?

    Same problem here. Fresh intall windows 7 64 bit and get random BSOD. And no problem in safe mode. Then I used system recovery to get rid of the Etron driver, the BSOD disappeared right away. Reinstall the driver and the BSOD is back again.

    Some of the issues are resolved by the latest Etron driver version 0.98 which is available only from the Gigabyte support site:

    I have the feeling that sometimes the mobo manufacturers consider the end users as beta testers.

    Etron USB 3.0 is junk.

    There is a label on top of my SATA connectors on my P67 Extreme4 motherboard. It reads "Connect HDD on SATA Port 0-5 as boot device."

    The problem is that the ports are numbered
    SATA3_M1, White
    SATA3_M2, White
    SATA3_0, White
    SATA3_1, White
    SATA2_2, Blue
    SATA2_3, Blue
    SATA2_4, Blue
    SATA2_5, Blue
    So there isn't a PORT 0-5 that I can see. Does the label mean that I can hook the hard drive to any port 0 THROUGH 5 or is it specifically calling out a port named "0-5"?
    Which one of these is "PORT 0-5"? I hope it is not "SATA2_5, Blue" because it is SATA2 and my SSD is SATA3.

    Thank you so much,

    I was hoping you would get an answer to your question. Im not sure which socket to connect my ssd to. Which of the 4 white slots are the Marvels (worst) ?
