1 out of 5 eggsDOA

Pros: IPMI worked out of the box. Came with several SATA cables.

Cons: System does not POST. Tried multiple sticks of RAM and PSUs. I ordered this board with a pair of KVR13LE9S8/4 mentioned in another review as working fine. After assembling the board, RAM, and PSU I can get into the IPMI interface fine. Turning the system on via the power button header button or IPMI results in no POST though. No video via IPMI or the VGA output, no POST beeps, no keayboard lights. System fans kick on so I know it's turning on. I then ordered Crucial CT102472BD160B.18FED which is explictly compatible according to Asrock's site. Still no POST. Updated to latest firmware made no difference. Have tried RAM in all slots, several known good working PSUs, and resetting BIOS. BMC light just blinks continuously.

Other Thoughts: After reading other people's issues with these boards and other forums I am hesitant to recommend this board to anyone. I'm stuck with an RMA now...

Manufacturer Response:

Dear Valued ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
By any chance you still have the board’s serial number which you returned? We did received the C2550D4I returned from Newegg.
However, we tested it but couldn’t verify the No POST problem. Did you unplug the 24-pin ATX power cable and remove CMOS battery when you reset the BIOS?
Please contact William@asrockamerica.com for assistance.

Thank you

4 out of 5 eggsgood for NAS

Pros: - 8 SATA ports
- ECC memory support
- Small
- Quiet

Cons: ECC memory support is limited, I had 4 8GB ECC Kingston memory sticks on hand when I ordered this board, unfortunately the board would not recognize the memory, I tested the memory on another board and was fine, (it met all the specifications) I was going to return the board based on this, I decided to buy the specific recommended memory and the board booted up just fine. I am using this for a free NAS server and could not be happier.

Other Thoughts: if the board accepted the Kingston memory I would of given 5 eggs, but based on the narrow selection of ECC memory I feel that 4 eggs is adequate.

Manufacturer Response:

Dear Valued ASRock Customer

We sincerely apologize that you having difficulty with ECC memory.
For this Intel C2550 server board, Unbuffered memory is needed.
Besides using our RAM QVL http://www.asrockrack.com/general/productdetail.asp?Model=C2550D4I#Memory , and since you used Kingston RAM to start with.

You can also look up Kingston’s official QVL for wider selection at link below.

5 out of 5 eggsawesome NAS Motherboard

Pros: Upgraded the BIOS and firmware to the most current works like a champ with FreeNAS. The IPMI is great because I have the NAS in a place not easy to get to so can remotely manage most things via the web interface. Uses ECC memory which is recommended for freeNAS an am currently using Crucial CT51272BD160B 4GB low voltage sticks. Uses regular DIMMs rather than the laptop size a lot of these C2550/C2750 motherboards use so more choices and cheaper memory. Tons of SATA ports, 12 overall. Easily saturates my Gigabit LAN when doing data transfers and uses intel based NICs.

Cons: No USB 3 on the back.

Other Thoughts: Would rather have had an active CPU cooler as the passive one does not cool the CPU very well unless you push a lot of forced air through the enclosure which ends up being louder than a regular CPU heat sink fan.

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 9.2.1.4

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 9.2.1.4 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.
