ASRock FM2A85X Extreme6 FM2 Motherboard

Posted by on Thursday, November 29, 2012 - 8:00am

The FM2A85X Extreme6 is the flagship motherboard from ASRock for the latest AMD APU products, which are based on the Piledriver core (updated Bulldozer architecture) and go under the codename of "Trinity". The motherboard is visually appealing to the eye and offers load of options from low wattage consumption to an 8+2 phase power configuration for increased stability while chasing down the higher overclocks. One impressive aspect about this particular ASRock flagship board, which we believe everyone in the market for a new Trinity-based system will love, is that the Extreme6 is being had for only $100 from Newegg!

ASRock FM2A85X Extreme6 FM2 Motherboard Review


We have seen the arrival of a new series of chipsets from AMD just recently, now dubbed simply an 'FCH', or Fusion Controller Hub (akin to Intel's 'PCH') . Codename "Hudson Dx", the series is split into four smaller divisions which will commonly we seen as A45, A55, A75 and the higher-end A85X. Each step up will in turn provide you with better and/or more of RAID, LAN, PCI, USB 3.0 and CrossFire support. Obviously, this does also reflect on the price of the motherboard showcasing these new arrivals.

ASRock's website list several motherboards utilizing three of the aforementioned chipsets, only the A45 is missing from the line-up. We could begin this segment with detailed reasons for why one would choose one chipset over another; however, with the A55 and A75 being essentially unchanged from the previous socket FM1 platform, we've opted to skip over those and focus on what the product in front of us features. What we will do is give you a rundown on the new FM2A85X Extreme6 that we have for review, and what the top end A85X it is packing will offer us all.

ASRock’s take on the FM2A85X Extreme6

If you weren't so sure about upgrading that old computer sitting in the corner covered with cobwebs, you can stop hesitating now. AMD's newest "Trinity" APUs have finally arrived! With more processing power and advanced onboard graphics, the new APU shows a lot of potential. In addition, the young and innovating company ASRock has exclusively brought a new auto overclocking function named "X-Boost" to all FM2 Series Motherboards, so users may have an extra 15.77% performance boost on the CPU! The FM2 Series starts with the most heavily armed FM2A85X Extreme6, which is equipped with Socket FM2, A85X (Hudson-D4) chipset, Premium Gold Caps, Digi Power, AMD Radeon HD 7000 series graphics and DirectX11.

Closer look

The FM2A85X Extreme6 is one of three motherboards to be released by ASRock based on AMD’s newest A85X socket FM2 platform, also known as Hudson D4. This particular platform is meant to go directly with the new Trinity APU the A10-5800K Quad-Core, and so that is what we will be using in our testing.

The FM2A85X Extreme6 is a beautifully laid out ATX motherboard with everything integrated being placed on a dark brown PCB (which some may actually say is black). The accents come in the form of the black slots and gold capacitors, with a touch of the purpleish-gray that the solid chokes lend.

ASRock uses an 8+2 power phase arrangement for the APU, with digital PWM adjustment, providing 6 phases for the CPU portion with the +2 supplying the iGPU and IMC. The phase is designed to deliver quality and ample power to get a high level of stable overclocking from the whole APU package.

The area around the socket is well laid out to where you should have no issues installing any size air-cooler. The only potential clearance issue that may arise would be from the lone VRM heat sink. Like we stated earlier the board is designed to be used with AMD FM2 processors which would include the following:


Speed (GHz)

Turbo (GHz)








































The Extreme6 uses a single 8-pin EPS for APU power delivery, fairly SOP these days. Fan connectivity comes by way of four 3-pin headers and has a total of six fan headers with four using 3-pins and two using 4-pin PWN. For a little extra stability to the PCIe lane's power supply, ASRock has included a standard 4-pin Molex connector above the first x1 PCIe slot.

One of the things we have been waiting for Intel to do, something that AMD has had for awhile, is to offer more than two SATA-III 6Gb/s ports. AMD has now implemented a total of eight of these ports into their A85X FCH, up two from the A75 which was top dog of the Llano series. Seven of them are location on the edge of the board in the image below with one residing in the I/O area of the board for eSATA, no additional third party add-in chips necessary for all of this SATA-III lovin'. All ports support RAID 0, 1, 5 and 10, along with Hot-Plug capability.

Just like the SATA controller the, PCI lanes are also controlled by the A85X and are still natively supported on all desktop FCH models . In the case of the FM2A85X there are three x16 length slots, with only the first operating at full x16 bandwidth when a single card is installed. When a second card is installed these changes to x8/x8. The last and final slot operates at x4 regardless, as you can see in the picture being only electrically x4. There are also two of each PCIe x1 and standard PCI slots.

The APU processors natively support memory frequencies up to 1866MHz (with the exception of the A4-5300's DDR3-1600), but the motherboard itself supports frequencies of up to DDR3-2600 when overclocking. There are a total of four DIMM slots for a total support 64 GB of memory. [Editor's Note: Please keep in mind that in order to utilize 64GB of memory that not only will you need an x64 flavor of OS, but also a non-Home edition. Win7 Home-Professional can only utilize a maximum of 16GB and Home-Basic just 8GB, a far cry short of 64GB. Win8 is 128GB in the base version, 512GB in the Pro and Enterprise. See: Here for the limitations on all past and present Windows OSes.  And now you know...yadda-yadda... G.I. JJOOEEEEE!!] 

Like any good enthusiast motherboard, the FM2A85X has an integrated power and reset switch right on the PCB. Good for those that likes to test in the open air. Of even more use, the clr_CMOS also is button resettable, and is located on the back panel as you can see on the last picture. An additional worthy note is that ASRock has kept the extreme-cooling enthusiasts in mind as well, providing a socketed BIOS to easily swap in different chips for your convenience.

  • 1x PS/2 Combo
  • 6x USB ports (4x USB3.0, A85X & ASMedia ASM1042)
  • 1x eSATA3 6Gb/s
  • 1x LAN port (Realtek RTL8111E)
  • 7.1 channel audio (Realtek ALC898)
  • 4x Graphic ports (DVI, VGA, HDMI, DisplayPort)
  • clr CMOS (Red LED illuminated)

Fletcher moves in when Bezoar's protective barrier is breached.


It’s nice to see that someone cared enough to build an enthusiast-grade motherboard for those sitting on a budget. ASRock has provided all the ins and outs of a very solid overclocking motherboard for the budget-minded AMD APU processors. The Extreme6 not only provide for good overclocking with its stable 8+2 phase power configuration but has all the extras as well. We are talking numerous USB 3.0 and SATA III ports along with support for CrossFire, and even TriFire setups (albeit with the third card limited to PCIe x4).

Not only does the board have nice features, it looks great inside the case and on top of that is rather well laid out. In today's market, you not only have to perform well, but also look good doing it. The FM2A85X Extreme6 shares the same basic visuals of ASRock’s other higher-end motherboards. There is plenty of space between the PCIe slots for video cards, and if the user decides to use a dedicated audio solution then there is an x1 slot that will remain open even in CrossFire configurations. In the end we are talking good air flow between the cards.

The only thing I saw out of place was the CLR CMOS jumpers on the board itself. They are place just along the second PCIe slot making it difficult to get to should you need, but on the flip side, ASRock have provided you with the rear-mounted button on the I/O panel. The onboard power and reset buttons are great for use by open-air benchers.

At $100 this motherboard when mated with any of the Trinity APUs is one heck of a deal. We do prefer the A10-5800K for it's unlocked multiplier, but also for the higher Turbo frequency and GPU clocks. However, for about $20 less you can pick up it's quad-core sibling, the A8-5600K, still get a great overclocking experience.
