5 out of 5 eggsThis is a Solid Server Board

Pros: I used this board as a foundation for a 6 drive NAS. It fits nicely into a Fractal Node 304 with plenty of room(thanks in no small part to being fanless). It runs cool and there were no issues with drivers when I installed the latest version of FreeNAS. All disks were detected and both i210 NICs as well. Also, the IPMI works like a champ! I had no VGA capable devices in my home so I used the java IPMI client to configure the BIOS and install the OS.

Cons: It isn't made of chocolate.

Other Thoughts: I do not like onions on pizza.

5 out of 5 eggsGreat little board

Pros: TONS of SATA ports! Surprisingly quick little processor. Very low power draw. A fantastic little NAS mobo.

Cons: the only thing I can knock so far is that only 2 ports are eligible for RAID. I never came across this fact in my research. In my case, it wasn't a big deal, as I only planned to mirror the OS drives and everything else is handled by software (Server 2012 R2 Storage Spaces with SSD and HDD tiers). That said, I was hoping to not burn the SATAIII ports for that purpose as I'm running the OS off a pair of old SATAII SSDs.

Since it wasn't intuitive to find, if you enable "Boot" but not "UEFI boot" on the 2-port Marvel controller, you'll get a new option during bootup to hit "ctrl-M" to get into the RAID config (after having switched said Marvel controller mode into RAID as well)

Other Thoughts: If they offered USB3.0 on this board, it would be even more amazing. But given that there's a free PCI-e slot (since you have a pair of well supported NICs already) its pretty viable to put some there.

For RAM, I used a pair of Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 ECC Unbuffered Server Memory Model KVR13LE9S8/4 and had no problems at all. I'm running it in a Bitfenix Phenom case with 2 2TB drives, 2 1TB drives, 2 240GB SSDs and 2 32GB SSDs.

1 out of 5 eggsDOA

Pros: None, never passed POST.

Cons: This board arrived DOA. Tried several different types of ECC UDIMMs and the board never passed POST. BMC LED would continually flash and no output ever registered via IPMI or a monitor plugged directly in.

RMAing the board with Newegg which will now put us back well over a week on a single day project.

5 out of 5 eggsRock sold after adjusting some settings

Pros: Rock sold after adjusting some settings.

Cons: Needs some adjustment to make it stable.

Other Thoughts: This is my second review after buying a second board and using the first board for over a month. I wanted to share some adjustments I had to make to the settings so that ASROCK can potentially change the defaults and for the benefits of others having stability issues.

1. The management interface uses a weird bonding mode with the regular interfaces by default. This will cause issues with smart switches since the same IP address will be used on both the management interface and one of the regular ethernet connections. It also causes issues when teaming is enabled.

To disable it, disable bonding it the management UI. Also disable interface eth0 and keep eth1 enabled. eth0 is shared with the regular jacks.

2. Disable "Turbo Boost" in the BIOS. This will cause a small performance decrease, but seems to increase the stability of the system.

3. Use the Intel based SATA connections first and disable the marvel controllers if you aren't using them. The Intel based controller seems to have slightly better software support.

4. Disable "Intelligent Power Management" for the Intel SATA controller. This seems to interfere with some hard drives.

After making these changes, the system seem to be very rock solid especially after making change #1.

2 out of 5 eggsMemory Compatibility Lacking

Pros: I've had my eye on this board for a while. It seemed like the perfect small form factor home server platform. I like the fact that it has IPMI capability, which eases remote management. Not sure of the full potential of this board yet (see cons)

Cons: Memory compatibility is lacking. There are very few items on the memory QVL. The only 16GB ECC module on the QVL is unobtainable. I've seen this many times before, and most of the time I've purchased memory from a reputable manufacturer I've still had success.

For this board, I purchased the KVR16R11D4/16I. I misread and thought it was dual 8GB sticks. I thought the motherboard would possibly run in single channel mode, but didn't. I bit the bullet and ordered another stick of the same RAM. Upon it's arrival, disappointment set in. I still could not get the board to post with two of the above RAM modules installed. Now I'm returning those items for another (hoping it will boot).

For a board that lists a maximum supported RAM at 64GB with 4 memory slots, this seems to be an unobtainable goal at this point.

Other Thoughts: Memory compatibility is lacking.

5 out of 5 eggsWorks out of the with FreeNAS

Pros: This board has everything I need for a home NAS:
-Low power usage
-ECC support
-AES-NI hardware acceleration for encryption
-Bunch of SATA ports (more than I'll ever need)
-Decent processor (4 core) for server usage.

Cons: None so far

Other Thoughts: I installed FreeNAS latest and it worked out of the box..
I just had to use IMPI instead of a monitor at first, as I didn't see any VGA output. First time using IPMI. On a MAC OS X with Mavericks, I had to tweak a little bit to get console access via IP working. Make sure you allow to execute the Java app under your Java settings. Also had to install XQuarz as X11 is no longer shipped with the MAC. After that, you can launch the Java app to "see" your video output/console, including boot process etc.

Thanks to the other reviewer who tested it first so I could by with confidence.

5 out of 5 eggsGreat Board

Pros: Low power consumption, a gazillion SATA ports, remote management, and Intel virtualization technology. Supports virtual media attachment from the management interface so that installs can be done completely remotely without any physical access to the machine.

Cons: Low number of USB ports and requires bleeding edge software to work with linux(Debian). I had to install enough of linux to be able to compile and install a kernel module from the free source code provided by Intel to get networking to work correctly.

Requires java v7 for console redirection. Many linux installs install v6 by default.

Other Thoughts: At first I was a bit disappointed with the board because I had massive trouble getting linux to work correctly due to the new networking hardware from Intel. I had to copy a large debian mirror onto a USB flash drive to get enough of linux installed to be able to build the module for the kernel from the Intel source code.

I didn't notice until later that you can remotely attach a ISO image or a folder to the device via a simulated USB device. That makes it possible to do a complete reinstall of the system without any physical access without relying on PXE boot.

I believe the management interface is set to DHCP by default so that you can find the management interfaces IP address via your router logs or DHCP server logs. In theory, the device doesn't need a monitor jack at all since the entire setup can be done without it. It is good that it's there though in case of an emergency.

As for the management console, it does require java v7 which was a bit of a pain. As for the quality of the redirection, it only provides an update rate of 5-10 fps but the console is mostly for setup. Once the OS is installed, you are probably going to be using either ssh(linux), vmc, or remote desktop(windows) to do most of the configuration.

2 out of 5 eggsNot ready for prime time

Pros: Large feature set
Many SATA ports
BMC capability
Low power consumption
Lots of potential

Cons: Not stable enough for business use
BMC crashes frequently taking entire operating system with it (Ubuntu 13.10 as of this writing)
Potential unrealized

Problems look to be firmware related as the problems are also found in the C2750D4I.

Other Thoughts: This board has the potential to be awesome but problems with the BMC and stability leave it off the list for serious production use. I have updated to the latest BMC and BIOS available from Asrock and it has helped some - now instead of crashing every other day, it's only once a week.

I'm using it as a media server so a crash/reboot every week is not a deal breaker but I would never consider it for business use today.

4 out of 5 eggsNice little motherboard

Pros: Low power, decent performance (for what it is), more than enough sata ports, ECC memory.

Cons: It bit pricey for what I wanted, I didn't really need/want 12 sata ports, but did want low power, dual nics, and ECC.

It could have better/more usb output only 3 ports supported and you use a jumper to select whether 2 on front or 2 on back.

The video is vga only (yeah I know server that is never plugged in but all my cables had moved or to hdmi etc, so initial setup was a bit of a pain).

Other Thoughts: I built a low power zfs based NAS server with this and a Norco ITX-S4 (separate review) case. Its low enough power that even with the drives installed I could use an external power brick + picoPSU instead of a regular power supply which means its almost silent (I have not done enough experimentation yet to be comfortable with unplugging the case fan).

As measured with a kill-o-watt (at the power) plug
- the 102W brick pulls 2.5W when not plugged into the server
- the server + brick when turned off pulls about 6W. This seems a little high but the network is active enough to being using WOL
- with a 256GB samsung SSD and 2 (I'm still waiting on the other 2) 3.5 drives installed.
* it idles at about 28 W
* running burn hitting all cores it pulls about 38W
* with the drives running and the cpu not being pushed it pulls about 35W
* its peak load during boot has been about 55W

So I could have gotten away with a 72W external adapter instead of the 102W adapter I choose.

The mother board supports both 20 and pin power connectors so I could have gone with a smaller picoPSU with a 20 pin cable. I wasn't sure so I went with 150W picoPSU with a 24 connector so that I wouldn't have to bother with a converter.

5 out of 5 eggsGreat board for FreeNAS 9.2

Pros: Four core processor, 12 SATA ports, two Intel NICs, IPMI, four 240 pin DIMM slots. It's really a great combination for something like FreeNAS. The performance has been excellent.

Cons: First board was DOA, second board needed BIOS update and IPMI didn't have MAC addresses burned in (all zeroes) and needed updated as well.

Other Thoughts: ASRock support was actually quite good through e-mail on this and were very helpful. They set me up with the utility to fix the MAC address issue and the rest was simple. Definitely recommend this board for this kind of use case. I would imagine that this would be good for something like PFSense as well.
