In the box

  • Quick Installation Guide, Manual, Driver CD
  • 2S SLI Bridge
  • I/O Shield
  • 4 x HDD Screws
  • 6 x Chassis Screws
  • Floppy Drive cable
  • 4 x SATA cables (2 x 90º cables)
  • 2 x Molex to SATA power cable
  • Front USB 3.0 Panel
  • Rear USB 3.0 Bracket

What I like about the extra hardware in the box is this USB panel. It has a space for an SSD, so it frees up a drive bay while giving you front-port USB 3.0 capabilities. This panel, on its own, would probably sell for $15.



Previous ASRock motherboards have been bundled with a heap of software for all sorts of overclocking or power saving modes. Thankfully, ASRock have been smart this time—they have packaged most of their utilities into one program, making it quicker and easier to install and uninstall. With their CD, apart from the driver updates, ASRock include three programs:

ASRock eXtreme Tuning Utility (AXTU)

The AXTU is not the tool we have come to expect from the socket 1156 and socket 1366 motherboard utilities. It shows the vast array of speeds, temperatures and voltages you would expect, and the tool allows you to control the fan speed on the fly. However, a successful CPU multiplier or voltage change requires a reboot. The main criticism about the overclockability tool is that it lacks the ability to manage the memory timings.

The OC DNA is similar to previous ASRock offerings, allowing users to share UEFI settings with each other. The Intelligent Energy Saver has received a trimmed down version—this one no longer states how much energy you are saving over a period of time, just the current voltage, speed, number of phases being used, and whether it is on or off.

ASRock Instant Boot

Another stalwart in the ASRock arsenal is its Instant Boot software. The idea behind it is that when you tell the PC to shutdown, the computer will reboot up to the point where the OS is loaded, then enter a low power mode. When the power button is pressed next, the computer will resume normal action, and you are straight into the OS without waiting to boot up. This worked at stock speeds, but failed to enter a low power mode when we applied the overclock.

ASRock XFast USB

The XFast USB tool is a small application that will attempt to boost USB input/output speed when activated. ASRock claims this little utility will increase USB 3.0 speed by almost double, and USB 2.0 speed by almost quadruple. We will test this with our USB 2.0 and USB 3.0 hardware when we receive it. There's a lack of information online as to exactly how this software works, and the line from ASRock is that the 'XFast USB software modifies part of the USB driver, allowing it to multi-task and enhance the performance - ASRock are continually tuning the performance for better results'. The proof is the pudding, as we'll see.

    Still using "ATI" on the motherboard.. I guess they don't want to use "AMD" or didn't get the memo.
  • anandskent - Monday, January 3, 2011 - link

    Why are there no results for the overclocked system in the benchmarks for either the SNB CPU article or this mobo article?

    Also, isnt that a fan header by the 8pin cpu power? it would make the board have 6 total then
  • IanCutress - Wednesday, January 5, 2011 - link

    The 3D Movement multithreaded benchmark was tested at the 4.6 GHz overclock. This is mentioned in the text, and in the graph for that benchmark.

    And yes indeed, that is a 6th fan header. It has no fan control in the UEFI or OS.

    "the H series taking advantage of the graphics on the processor die"

    Sorry if I missed this, but I wanted to be sure on something obvious.

    P-series = No onboard graphics, discrete only. That's clear.
    H-series = Onboard graphics... but can it ALSO USE DISCRETE GRAPHICS???

    Maybe it's so boneheaded it wasn't worth pointing out. Maybe I should have a second cup of coffee.
  • sviola - Monday, January 3, 2011 - link

    From what I understood, none have on-board graphics, and the H series is designed to use the on-chip (CPU) graphics, while the P series is designed for discrete graphics (altough you can use the on-chip graphics as well).
  • justaviking - Monday, January 3, 2011 - link

    Thanks. That is what I assumed, but I didn't see it explicitly spelled out.

    Sorry about the sloppy terminology. I mean "on-chip" when I wrote "on-board". I understand the difference. Thanks being gentle with me.
  • evilspoons - Monday, January 3, 2011 - link

    Not quite. If you Anand's article from today about Sandy Bridge, I got the opposite impression.

    P can not use the on-CPU graphics at all but supports full overclocking of CPU and memory. H can use on-CPU or discrete graphics (or both simultaneously, it would seem), but only supports memory overclocking. Z is meant to fix that by allowing full overclocking and including the "FDI" (flexible display interface) needed to access the on-CPU graphics processor.
  • bah12 - Monday, January 3, 2011 - link

    What I'm confused about is this. The K series gives us the faster GPU, and the ability to fully overclock the cpu. However you cant use the GPU since the whole reason for getting the K sku is the overclock, thus the P series board and no GPU.

    Where does this leave QuickSync (arguably the top selling point)? From what I understand we cannot have a fully overclocked QuickSync CPU right?
  • ericore - Tuesday, January 4, 2011 - link

    Overclock option is only for CPU + Discreet GPU (limitation of a current motherboards; a stupid one at that; cheap Intel bast****)

    QuickSync comes with i5 and greater regardless of the motherboard (it is an instruction set; all of which are built-in to CPU)

    I want want AMD Bulldozer to kill your royal heighness, and bring hardware market back to democracy.
  • vol7ron - Monday, January 3, 2011 - link

    You forgot to mention that P allows for SLI/x-Fire, whereas H does not (since it only supports one discrete gpu).
