4 out of 5 eggsESXi whitebox server

Pros: Good price for features.
Works with ESXi with standard installer. No custom install image required.
IPMI is *AWESOME*
LOTS of SATA ports

Cons: Unbuffered RAM. Really???

Almost no one makes 16GB UDIMMs, and those who do, charge a mint for it.

This makes it very expensive to put the full 64GB of RAM in this board. I just purchased the 4 x 16GB sticks from another site. $365 x 4. **OUCH**.

Other Thoughts: Very expensive RAM notwithstanding, this is quite a nice board. I wish it supported 128GB of RAM. It may have, if they'd used something other than Unbuffered memory.

Having read other reviews where customers had heat issues, it makes me think it'd be nice to hear from ASRock on what some best practices would be for those of us using this board for VM hosts. I'd like to keep things performant, but also protect the investment.

Manufacturer Response:

Dear Valued ASRock Customer

Thank you for purchase and review.
Intel Atom C2000 series only supports SODIMM, UDIMM, VLP UDIMM at maximum memory capacity of 64GB.
Memory makers decides on the product pricing and availability based on the market demand and the prospect of mass production.
Limited selection of 16GB UDIMM module is due to the availability from most memory makers.
C2750D4I is mainly and ideally designed for Cold Storage application so CPU and storage controller heatsinks are passive. But it is always recommended to use case fans to increase airflow when looking at other application and the number of HDDs in operation.

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

Thank you

1 out of 5 eggsJunk, Worse than a desktop board. ASRock is worse than that.

Pros: Low power draw.

Cons: This board was bought along with three ASRock Rack 1150 board for testing, this as low power file serving, two Xeon for VM hosting, one client. All the "server" boards has had ridiculous -severe- problems. Support is worthless, literally don't reply.

This one used to intermittently drop off the LAN; BMC would respond but KVMoIP would only sometimes work. I would on more rare occasions, have drive issue, but that may be Marvell.

Long story short, ASRock Rack doesn't respond, production work got in the way of diagnosing test systems. About 10 months later, board was pulled for a temporary tertiary backup/failover role. A Mellanox ConnectX-2 card was installed for access to a storage/migration 10G VLAN.

That's when I noticed, over RDP that went accidentally went through 10G VLAN, that the Intel NICs were OS disabled.

Let's get the L1 tech (excuse) nonsense out of the way:

*All firmware/BMC/drivers are updated, current. So is the OS.
*(ECC) RAM was pulled from fully functional systems.
*HDDs have varied and include DC SATA drives, all have been functional in other systems.
*Thermal mishandling?
-The board is in a *2U* chassis with five fans.
-It's the only active board in a 15U rack.
-HDDs are low power 2.5"s and not even in line with the board, cage has a fan.

Now I don't know if it's the onboard Intel NICs (unlikely) or junk PCIe components (likely, see below*); I do know that by now the warranty is one month gone, even with a replacement, I'm out a serious amount of time on the diagnostics and money to complete these systems.

Tim? I wrote the report the way we wish end users would write them: even the filenames were fully descriptive of the hardware and issue depicted, with my email and ticket number, in case someone down the line got the ticket without email headers. They can't handle responding.

Tech is supposed to be about assisting people in work, server class even more so.
ASRock, at least in my experience is about causing me more.

So if you want onboard NICs not to simply work under ideal circumstance, wasting an extra RU on what ASRock sells in a 1U solution, by all means, pull the trigger.

*(The Xeon boards would fail with Intel Neteffect, Brocade 1020, and a couple other 10G LAN cards, some that are options on SLA type systems from Dell, etc. They would hang on OpROM load in dramatic fashion - they would push 9W cards to draw 20W and higher, to 150C, system temps would be at 80C and rising. Try a 16x 3.0 Quadro? No problem. LAN cards (to their credit) went back into other systems and can push 10G bidi under test, daily doing 6G disk writes.

Every component, E3 Xeons included, worked and continue to work in other systems.

Those ASRock boards don't just "not work," they are a hazard. I spent three work days writing a full report with BMC screencaps, and camera photos including an attached wattmeter. No help. Irony? Their B85 ITX -which has been great in other uses- booted fine

Other Thoughts: I have a dozen+ ECC class boards installed here. None are ASRock Rack, and I won't even buy another, no matter how compelling the feature set.

5 out of 5 eggsSuperb server grade motherboard

Pros: Executive level brief: If you're in the industry, and used to working with enterprise class hardware, and hate running on consumer oriented hardware, this is the board for you.

Environment:
FreeNAS 9.3
Jails: Plex, Transmission, Sick Beard, Couch Potato, SABnzbd
Silverstone ds380
1 Verbatim 16GB USB Nano
6 WD 3TB Reds
1 Intel 730 240GB SSD for L2ARC
1 Intel 5300 80GB SSD for ZIL
32GB of Kingston KVR16E11K4/32
1 Intel EXPI9301CT

The features and components of this motherboard within my setup, perform superbly. Setup and, recognition of the hardware was surprisingly simple, I plugged stuff in and, *poof* it worked. The board shipped with the latest firmware update and, is every bit as stable as one would expect of a motherboard targeting server grade services and features. The Avoton SOC processor and its eight cores are more than sufficient for running all the jails, providing file services, and running two 720P Plex transcodes simultaneously. I must admit to having concerns about the ability of the Avoton processor to keep pace with applications utilizing only a single core, such as Samba's smbd but it soundly put those fears to rest. A CIFs copy from, or to the C2750D4I FreeNAS box is capable of saturating the 1 Gigabit link with ease.

The IPMI interface and feature set is robust, stable and really the delineating factor of this board. I work daily with iDRAC cards on Dell M1000e chassis, 710HDs, R715s & Sun ALOMs interfaces. This little IPMI card compares well to those enterprise grade solutions. The remote KVM, media mounts, and logging are really top notch. Some of the more nuanced features like using a single LDAP server as an identity source, NTP synchronization, SNMP traps, and more are amazing for those of us that need and utilize those types of features and this little ITX board supports them all.

The SATA controllers from Marvell appear to be playing nice with OS and file system. I haven't had the need to establish performance counters or dig into anything so that's a good sign.

Odds and ends: The abundant fan connectors are appreciated.

Cons: ASrock's memory compatibility list leaves much to be desired, and the supplier of the 64 GB Unbuffered ECC DIMMs is an expensive bit player. I ended up searching memory makers websites which were accurate, and up-to-date.

The lack of an internal USB port kind of stinks. but this is nit picking on my part. I to keep my hardware clean looking with minimal chances of mistakes happening, and hiding my micro USB flash drive inside the case would have eliminated possible accidental removal of the USB stick.

The use of Unbuffered ECC RAM makes maxing out this board's memory to 64GBs prohibitively expensive. There's one supplier, it's not available in the U.S, and you have to purchase the RAM through ASRock, frankly is amateurish.

5 out of 5 eggsKingston memory that works but not listed

Pros: Small and appropriate for file server.
I have this as part of ASRock's 1U server with 12 data HDDs. FreeBSD, with LSI HBA with 2 SAS (SFF-8087). 12 data drives (4 from intel controller +8 from LSI), 1 zfs cache(from intel controller), and 1 for root system (from intel controller).

Cons: 1) Marvell controller (8 drives) has not-as-good support in linux/BSD, but this is not ASRock's fault.

2) I'd love to have a jumper that disables BMC at low level.

Other Thoughts: Here is a memory that works with the board, but is not listed on the site:
Kingston 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 Server Memory Model KVR1333D3E9SK2/16G

1 out of 5 eggsNot impressed at all

Pros: Low Power comsumtion small form factor
loads of sata ports and up to 64gig ram
Ecc Suppport

Cons: Extremly unstable overheats like crazy they shoud have included a small fan
No Raid options other than 0 and 1
useless for data center home server applications

Other Thoughts: If you are not concerned about the data integrity and or you have other backup optoins this is a good choose for you with tons of sata ports and memory support. i am using it as a test web server i would have liked some raid option provided it has 12 sata cables so most likely people are going to be using it in home or small business environment.

Manufacturer Response:

Dear ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
Depending on the number of storage medias in the configuration and their I/O load, case fans should be added accordingly based on the operating temperature.
The onboard Marvell SE9230 is capable of RAID 10 configuration when there are 4 HDDs connected.
Same board is also equipped in our 1U12LX-C2750 which is ideal for cold storage and data center application at link below.

3 out of 5 eggsInteresting board

Pros: Sturdy high quality board. Booted up nearly immediately and accepted the Crucial ECC unbuffered ram that I had happened to have laying around.

Cons: Worked great in every aspect until I installed BMC update 00.17.00 and lost all BMC network connectivity. A big selling point for this motherboard/processor combo was the IPMI. I hope there's something ASRock can do about my situation and have already opened a ticket with them. Until I can have this issue resolved it'll have to be 3 eggs at best.

3 out of 5 eggsWorst IPMI Web Interface Ever

Pros: Low power
Lots of SATA ports
8x PCIe port for expansion

Cons: No USB3
Additional onboard SATA controllers have issues
IPMI web interface is useless

Other Thoughts: As long as you can set it up and leave it running, it works fine for quite a while. If it's headless and you need to work on it though, the IP KVM is impossible to get working.

I'm thinking I should have gotten the SuperMicro version.

Manufacturer Response:

Dear ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
Unfortunately, mainbaord does not came with USB 3.0.
For more information, please visit specification link at " http://www.asrockrack.com/general/productdetail.asp?Model=C2750D4I# "

BMC iKVM relies on Java and security clearance in order to run properly. Often time a few security popup windows from browser and Java need to be eased to grant iKVM to launch. In some cases, anti-virus also needs to be configured. Updating BMC firmware version can also renew the certificate.

If you have any technical inquiry, please contact us with detail problem description (SATA controller) at william@asrockamerica.com. We will assist you shortly.

5 out of 5 eggsUpdated Review

Pros: Mini-ITX server grade motherboard with IPMI, 8 physical cores, 32 gigs of memory (in practice), and very low power consumption (22 Watts!!).

Cons: The board requires an active cooling solution, not just on the CPU but on the chipset as well. Otherwise, instabilities may occur. Do NOT be fooled by the small passively cooled heat-sink on this board. It will run hot!

Other Thoughts: I posted a review on here earlier complaining about stability problems. William from Asrock America contacted me and offered me (and I say this with over 2 decades of system builder experience) the best consumer technical support I've seen from a company. He worked with me for almost a month tracking down the issues I was having, experimenting with new bios and firmware versions, and ultimately replacing the board. Even after replacing the board, he kept me up to date on the problems discovered. While I was a bit disgusted with this motherboard initially, this sort of customer service has totally sold me on the company. PLUS! We solved the stability issues I was having.

I can confidently saying I've been running this board and pushing it pretty hard for a while now with 0 problems. I'm actually planning to purchase another. While I still wish this board came with a better heat-sink, I can work around that with a good case.

I mentioned in my previous review that if the problems on my board were resolved, I'd give it 4 out of 5 stars. I'm giving this 5 out of 5 because of the superb customer service experience I had.

4 out of 5 eggsMy experience thus far

Pros: Perfect home server board. I'm using this for a home NAS running FreeNAS 9.2. SATA ports for days, and the fanless heatsink is a plus in my books.

Board stays pretty cool even in a tight case like the Fractal Design Node 304 with the CPU and motherboard temps staying right around 48 Celcius.

Low power usage is great.

IPMI is much more useful than I originally anticipated, and is a feature that makes the server unbelievably easy to use. Very easy to configure and the web GUI is very user friendly.

Cons: The board is quite pricey, but you really do get what you pay for.

Boot times are quite slow, but I don't really know if I'd consider that a con on a server board that's on 24/7.

It is next to impossible to find officially supported memory for this board here in Canada, so you do end up having to buy non-officially supported RAM.

Other Thoughts: I got the board to boot using KVR1333D3E9S/8G memory purchase here on newegg.
