Pretty good

Pros: I am in the IT business. Bought for running Hyper V VM's.
Performance is great.
Only E-5 motherboard out there in such a small footprint.
ASRock service is great.

Cons: Had issues with memory recognition ~ sent in twice > mostly a physical insertion issue.
Not sure why the tolerances are so high but a concern for future reliability.
Wish it use standard size RAM ~ ECC 16gb sodimm are expensive and rare.
Narrow ILM > is a pain to find correct cooler.
BIOS below P2.10 does not support Haswell but ASRock support will send correct one.

Overall Review: Still, with all of the deficiencies it is the most powerful mini-itx out there.
If maintains reliability then it will be fantastic.
If not ~ I will be sad as I have high hopes.
Not the first mini-itx server board I've use ~ all still working well albeit E-3 with standard size RAM.
No issues with any of those.

ASRock Mini for president!

Pros: - size. I have installed this mobo into an NFC S4 Mini chassis.
- four memory channels. I needed the best available performance so even if SO-DIMM memories were more expensive at time of buying, I went for this board (instead of the Asrock X99E-ITX)
- dedicated IPMI connection. It is normal in server world but helps a lot also when you do software prototyping :)
- onboard VGA, so you do not need to replace the already installed NIC with a videocard if something goes wrong
- PCI-E bifurcation. So it made me to build a tiny server with two 40G NICs (each uses x8 lanes via a PCI-E splitter)

Cons: None of these 'Cons' worth an egg:
- narrow ILM, but it is not a serious con, only limits the choice of available CPU heatsinks I could use.
- SO-DIMM memories. but hey, 4 slots need serious amount of space on the mobo.
- boot time is pretty long, but server boards are not about frequent reboots.

Overall Review: I have also received the board with pretty old BIOS so had to insert a Haswell first to do a BIOS upgrade. Now it runs nicely with a Broadwell ES (engineering sample) E5-2650L v4.
I do hope that boards sold recently come with latest BIOS.

Dear Valued ASRock Rack Customer,

Thank you for your honest and knowledgeable review! Other than temporarily trying to find a Haswell (v3) to get the board to POST, then updating the BIOS to Broadwell-ready version P2.10, all you need is give me a call. I will send out a preflashed BIOS chip to you at no cost.
Please contact me at 909-590-8308 Business hours (Pacific time) or http://www.ASRock.com/Support/tsd.asp

Thank you

Second defective motherboard in a row - Two RMAs and two months later - still stuck. Unless there is some killer feature you need - look elsewhere.

Pros: Looking for an mini ITX board with Xeon® Processor E5 v4 Family support with SR-IOV support for the PCIe slot - this was the winner - until I tried to get it to run.

Cons: Motherboard 2 - Bad DIMM Slot. 1/4 slots does not function. This one is also going back.

Motherboard 1 - RMA - BIOS settings fail to save on power off. System defaults to PCIe graphics - with GRID GPU card (no video outputs), so the BIOS is inaccessible once the system is built - useless.

Initial observations - BIOS defaults - if the BIOS is lower than version 2.1 - no Broadwell support. You have to find a Hawell CPU - put in it, and update the BIOS. This is can be anywhere from a nuisance to a game over depending on what hardware you have laying around. Also - the default graphics are to the PCIe slot, which sucks if you graphics card is a multiuser GPU with not video output - the screen just goes black. Had to take the whole system apart to get the graphics card out to get back to the BIOS settings screen.
This board has the narrow style CPU mounting - another frustration and week delay to get a new CPU cooler ordered. It's not mentioned anywhere - unless I missed that part.

Overall Review: Two failed motherboards and no way to return it really sucks. I'm stuck with this thing. The documentation is pretty good. The VGA connector on the motherboard is pretty flimsy. And that BIOS BMC inItialization think that delays the boot for 30 seconds should probably be off by default.

Manufacturer Response:
Dear Valued ASRock Rack Customer,

The 1st time you RMA the board to us, it was found that one of the memory latch was broken, CMOS battery and BIOS chip were also missing. Despite the physical damage, we still replaced the board for you exclusively. And the replacement unit WAS thoroughly tested prior to shipping to you. This also means that all memory slots were fully populated when the board was pretested. Now that we have received your RMA return the 2nd time, we found that that A1 memory slot was shorted, the plastic slot is deformed, a couple of gold fingers inside the memory slots were dislocated. This is a typical problem when memory module was improperly installed or even incorrect memory used. But again despite this physical damage to the board, we still decided to replace the board for you fully tested. Our product page clearly shows the CPU socket mounting type is narrow. To be exact, it’s called Narrow ILM in case you don’t already know. Also for your information, unit being returned with physical damage is actually subject to a service charge and it’s not covered in manufacture warranty. I hope all these favors still make your day.

Thank you

Excellent mini ITX home server motherboard

Pros: Primary pro for me, it supported VMware ESXi where I can run multiple different servers if I choose to.
My ESXi summary here: https://drive.google.com/a/cipher.id.au/file/d/0B4Zs8KKIzLWtZHlpdnVmMHNlRHc/view?pref=2&pli=1 and it is working like a dream.
The MB is running DDR4 32gb ram (4x DIMM) and supports a Xeon CPU. Its compact and fitted nicely into a Cooler Master Elite 130 case.
This MB is a tiny ITX beast.

Cons: Primary con, I couldn't water cool this system with closed loop manufactured CPU cooler like Cooler Master Nepton 120XL.
The MB does NOT come with a square ILM!!,.. this MB comes with the narrow ILM bracket. (see differences here: http://www.servethehome.com/narrow-ilm-square-ilm-lga2011-heatsink-differences/).
And I failed to comprehend the details on the specs page at ASRock here: http://www.asrockrack.com/general/productdetail.asp?Model=EPC612D4I#Specifications
It states under processor system > socket > "*Please use narrow type CPU Cooler" which basically should read, this MB has a narrow ILM not a Square ILM. (my mistake for not enough research) and as such, the Cooler Master Nepton 120xl bracket couldn't be secured to the narrow ILM and I had to purchase a separate narrow ILM CPU cooler like the Dynatron R14 listed here http://www.newegg.com/Product/Product.aspx?Item=N82E16835114119 .

This then resulted in the 2nd con for this board, because Ive had to resort to air cooled CPU with the Dynatron R14, the system cannot make its mind up about the fan speed. One minute is on 100% and then next its running at 10 or 20%. This is happening constantly though out the day as the system is in ear shot of where I sit. CPU temps are all in the normal, cpu utilization is not spiking on any of my virtual systems. So I have no idea why the MB cannot stabilize the CPU fan. Had I been able to water cool this beast, I'd probably would care less because I would be able to hear it.

Overall Review: I recommend this MB to anyone who wants to build a home server solution. Especially those want to run VMware Hypervisor ESXi
For an ITX size MB when fully spec'd out, it packs a good punch for the $$, with its support of server grade CPUs and high memory capacity in a small form factor.
Apart from the cons, I'm still happy I made the right choice and purchased this MB for my home server solution.

My kit list in the end was as follows:
1 x Intel Xeon E5-2640 v3 Haswell 2.6 GHz LGA 2011-3 90W BX80644E52640V3 Server Processor
2 x HyperX Impact 16GB (2 x 8G) 260-Pin DDR4 SO-DIMM DDR4 2133
1 x Cooler Master Elite 130 - Mini-ITX Computer Case
1x Noctua NF-F12 industrialPPC-2000 PWM 120mm 2000RPM Case Fan (replaced the Cooler Master case fan)
1x Dynatron R14 60mm 2 Ball Intel Sandy Bridge <-BOO I wanted water cooled.
1x SAMSUNG 840 EVO MZ-7TE250BW 2.5" 250GB SATA 6Gb/s
1x ENERMAX EDF550AWN 550W ATX12V / EPS12V 80 PLUS
