5 out of 5 eggsEats through Cinebench like a Cinnebon

Pros: + Well, pretty much one of the only choices for building the "16 core/32 thread Xeon monster."
+ Supports PCIe 3.0!
+ BIOS lets you setup everything easily. Posted fine first time.
+ Supports quad channel server or regular desktop memory. Can not mix both. I used two sets of Model F3-1866C9Q-32GXM

Cons: - No sound. This is a server motherboard however, so understandable. I used a ASUS Xonar DG 5.1 Channels PCI Interface Sound Card
- No 10Gbit Ethernet output. Can be added.
- No USB 3.0/3.1 outputs. Only 2 USB 2.0 outputs. I used a Inateck PCI-E to USB 3.0 5-Port PCI Express Card
- Some of the center mounting holes for the motherboard may not line up with most desktop cases. However, you can just use some hard foam and double sided tape to remedy this or drill and thread the two needed holes.

Other Thoughts: - The price of this MoBo has been jumping up due to popularity of the 16 core/32 thread build, so get it sooner then later. I got mine for $309.99.
- Make sue your computer case supports SSI EEB layout. It's a server board and wont fit in some full tower ATX cases.
- A single, higher frequency processor can out perform both E5-2670's in games in terms of power consumption and speed, but the cost of two Xeon E5-2670's blows away an equivalent single core processor.

- The 16 core/32 thread build is awesome as it can encompass, a gaming computer, work station, or server all-in-one.

5 out of 5 eggsImpressive!

Pros: Absolutely everything! This board Rocks.

Cons: Nothing these are a very high quality board and would recommend ASRock to anyone especially someone looking at ASUS. Do yourself a favor and stay clear of any ASUS products.

4 out of 5 eggsExcellent value board in this market

Pros: While it's hard to say this board is cheap, it is among the cheaper dual socket 2011 boards out there.

Excellent board layout

16 DIMM slots is great to see on a board this size. Being able to get kind of memory installed in an E-ATX sized package while still providing this many PCI slots is great.

Cons: A few more USB ports on the rear IO would have been nice.

No onboard audio. I can't really fault the board for this as it doesn't claim to have them, but for a workstation type board this feature would have been a nice touch.

The fan speed control leaves something to be desired. Every modern motherboard I've used has provided support for controlling 3-pin fans through some sort of software. This board offers no control for 3-pin fans and runs them at 100% all of the time. Even the access to the voltage through the BIOS that third party software like Speedfan is locked so no control whatsoever can be had. While this is more of a server grade part and that "creature comfort" may not have been a high priority I would have liked to see it.

Other Thoughts: Overall I'm very satisfied with this board. I ended up just buying a separate fan controller and sound card which probably put me to a price point where I could have potentially found a board that had these features from the start...

I would however recommend this product as I've had nothing but good experiences with ASRock Rack products in the past and that trend is continuing through this board.

5 out of 5 eggsYou need a special power supply, case

Pros: Very easy to setup. Motherboard layout is clean and the front panel connector was a breeze. Enough fan headers you will not run out. _All_ of the fan speeds are adjustable in BIOS.

Cons: 2nd 8-pin CPU power connector is required. Some cases might not support the SSI EEB form factor.

Other Thoughts: I was worried this motherboard would not work in my computer case. I was wrong. It's an In-win Dragon Driver full tower case, Extended ATX compatible. And guess what, the various holes for SSI EEB were already pre-drilled. Yes you read that I didn't have to make _any_ modifications to install this motherboard in my EATX computer case. Installing it was a breeze but holey cow it is massive at 12x13 inches. Since power supply only has one 8-pin 12v cpu connector the computer boots up just fine but without the 2nd Xeon. It's an older 650 W Thermaltake that I bought seriously about 5 years ago so its time to upgrade anyway. The manual for this motherboard says it is compatible with the 20 or 24 pin ATX power supply and will work with either the 4 pin or 8 pin 12V cpu connector. Sorry I can't tell you which power supply to use just yet because I'm still researching. The heatsinks I'm using are Cooler Master Evo 212's on the 2 Xeon 2670 V1 processors. Keeps 'em nice and cool. I'm very happy with the 4 extra SATA3 6gb ports on a secondary controller in addition to the 2 ports you get from the 602 chipset. As my RAID array is currently rebuilding at 150 MiB per second, I ran benchmarks on my Samsung Evo SSD. Sequential Read: 506 Sequential Write: 526 Random Read (IOPS) 51349 Random Write (IOPS) 46685. It will be much faster once I enable Samsung Rapid Mode. And finally, the cherry on the ice cream: I didn't have to reinstall my operating system. My Windows 10 installation just seamlessly transitioned to the new motherboard as if I had never even changed it. It was that smooth. I have not installed a single driver and I probably won't need to. Best upgrade evaAR!

Manufacturer Response:

Dear Daniel,

Thank you for purchase and review. You can split open the EPS 4-pin 12v connector into two (if separable) and use both 4-pin ends to connect to each of the EPS 8-pin power header of the CPU socket BSP1 and AP1. But this is still not entirely safe if the CPUs will be under heavy load. The PSU we use on our bench, for example, is CoolerMaster V850, which features two EPS 8-pin 12v power headers. This board in specific is using Square ILM heatsink form factor. More variety in Dynatron’s website.

If you have any technical inquiry in the future, please contact me at

Thank you

5 out of 5 eggsStop shopping and buy it, you will be happy you did

Pros: 14 onboard SATA ports (check the picture, its really cool) , 4 onboard gigabit nics, 16 ram slots... this thing is loaded
Setup was a breeze (dual Xeons, 64gb of ram and every pci slot was full)
Plenty of room between CPU's for a large fan, I used 2 Nactua setups that were a large heat sync and a total of 4 fans (2 per CPU)
That brings me to my next point, there are a TON of fan headers on this board, I have 4 cpu fans and 4 case fans all connected directly to the mb

Cons: only 2 external usb ports (no big deal, usb cards a re cheap)
this board takes forever to post and always reboots twice (IE you turn it on, it posts, gets to where windows should start, re-boots and starts up... Its very odd but not uncommon for server boards from what Ive read, just be patient and watch the error codes when installing new hardware, new additions will add to the post time on their first power up after installed)

Other Thoughts: This board replaced an ASUS board I bought, the ASUS board wouldnt play well with any of the available vid cards I had. A biuld on this scale allways takes a bit more time but I honestly am grateful that the ASUS board wouldnt work becasue it brought me to this board which is better in so many ways (IE more SATA ports, more ram slots, more total ram capacity)

1 out of 5 eggsMy first ASROCK MB...never again

Pros: Absolutely none.

Cons: First of all, looked like I was sold a used board. The packaging seemed off. Everything was there though and I got over this quick due to the cost of the board and its features. Finished building my new server yesterday and was excited about my new MB. Booted up and first thing I noticed is that it was not seeing CPU #2. (Intel dual E5-2609s) Said not present. Troubleshooting today, so I pulled it to make sure no pins were bent. All good. Put it back in place and still no go. Swapped CPUs and the same thing. CPU#1 that was working in socket 1 was now not working. Tried calling ASROCK support but just kept getting passed back and forth via robo prompt. Im assuming they're closed for Christmas but no message indicating so.
I've already spent most of my Christmas dealing with this MB so Im calling it quits and will give them a call tomorrow.
Never had issues when buying Gigabyte, ASUS or Supermicro boards, so as of today, I would not recommend a ASROCK MB. Especially this one. Would love for ASROCK to prove me wrong though. We'll see how tomorrow goes.

-Does not see CPU
-CPU sockets don't line up all that great.
-Board looks refurb. May not be ASROCK fault

Manufacturer Response:

Dear Derrick,

ASRock Rack conducted an expedited RMA service to replace your unit. Replacement unit is brand new as well as your original one, and it has been fully tested to ensure both CPU sockets can detect dual CPU configuration.” Also, the returned unit has been found with a broken locking latch on memory slot A1. We are crossing our fingers the replacement unit will be fine with you.

If you have any technical inquiry, please contact me with detail problem description at
I will assist you shortly.

Thank you

4 out of 5 eggs

Pros: space for lots of ram and drives. dual socks. Supports a wide range of hardware

Cons: two of the mounting screws are located under the tabs for the ram. It is very difficult to tighten these screws. Especially in a tight case

Other Thoughts: Ensure your case can fit this. ITs a large motherboard. NOT E-ATX but SSI-EBB

5 out of 5 eggsgreat board, smokes SM X9DAi and ASUS alternatives

Pros: Worked with ES chips right out of the box
16 RAM slots
Tons of slots for SATA drives
Rock solid
Great value, much $$ / feature than the competitors

Cons: One bad RAM slot

Other Thoughts: I have this board set up w/ 128 gb of ECC registered ram (8 16 gb modules), two ES V2 chips, and a bunch of SSDs and physical drives. My OS is Fedora 20. It's running like a champ- the most stable board I have out of 15 in the cabinet. The only issue I have is one of the RAM slots doesn't work... but aside from that I couldn't be more pleased after about 5 months of uptime. Customer service is also top notch. I also own the X9DAi (it's ok) and have returned a couple of the ASUS boards. This one is by far the best, and we will be buying more.

5 out of 5 eggsGreat FreeNAS MOBO

Pros: I built this with a NORCO 24 drive case with 3x 6tb drives and 3x 4tb drive. Installing freenas went on without a hitch no weird driver issues or crashing. Performance is pretty good. CIFS share transfer maxes out the 1gig nic card with Plex and owncloud jails running in the background. With an average 15% CPU usage on a Xeon E5-2620 and 32GB ECC ram.

Cons: Only real compliant are the instruction are that great but if your a techy person you can figure it out.

Other Thoughts: If you want a monster FREENAS box this is the way to go.
