Great board when it works.

Reviewed in the United States 🇺🇸 on August 11, 2016

Verified Purchase

I originally bought this board in January 2016, but didn't get around to building my FreeNAS server until March. To my dismay, I never could get the board to post. I worked with someone at ASRock, who eventually sent me a replacement. Upon installation, the second one didn't seem to work either, initially. For the life of me, I can't remember what I did, but I got IPMI to work with the remote console. I got everything working eventually and even upgraded the firmware. For the next several months, it worked flawlessly. I was running FreeNAS and had installed Plex. The Atom processor handled video transcoding without a hiccup. I had a power outage sometime over the summer and even though the server powered back up, the OS didn't boot. Connecting to it via the remote console, I was able to do a clean power up and everything worked again. Until last night.

Last night, we lost power again for about 30 minutes. When the power came back on, the server started up again. I tried logging in to FreeNAS through the browser and noticed it couldn't find the ip address. I then tried connecting through the remote console and couldn't see anything. Apparently, it is no longer posting. I've just emailed ASRock's support in hope that they'll replace the board again.

Update:

I figured out what happened. The power outage apparently corrupted the bios. I took the drives out and then removed the battery for about 30 minutes. Then I put it back together and got it to post and then I had to reset the boot sequence in the bios. So everything works again. I also ordered a UPS (CyberPower CP1500PFCLCD) this week so I don't have to deal with the loss of power anymore.

Initial problems with firmware which were fixed by update, otherwise pretty stable.

Reviewed in the United States 🇺🇸 on July 26, 2014

Edited on April 20th, 2016:
One of my boards failed after about 1.5 years. I was able to RMA the faulty board and received a new one about 2 weeks later.

Edited on August 11th, 2014:
Firmware updates BMC(00.17.00) and BIOS(2.4) solved the fan issues and do not appear to have brought on any new ones. This makes me feel that I can adjust the review score from 3 to 4 stars.

On a side note, I have been looking at the power consumption of this board...so here come some numbers.
On a minimalistic FreeNAS installation (with 'powerd' enabled) with three 4TB WD RE4 (around 9W each) it idles at ~54W total (measured at mains). If we deduce 15% off of that to account for PSU inefficiency, the board on it's own is drawing about 23W idle. According to Intel documentation on the C2750, TDP is 6-20W so it seems that FreeNAS is not utilising all the power saving features in a default configuration apart from me having enabled 'powerd'.

I had read somewhere that the ASPEED IPMI/display adapter is a bit of a hog but since I have not tried running the board with the onboard display adapter disabled I cannot say how much power is getting lost through that. The ASPEED chip is always pretty warm to the touch which means that some power is being 'wasted' there when no display output is required 99% of the time. I cannot say that this is necessarily a flaw, but at least there is definitely some room for improvement.

Have had it for about a month at the point of the initial review write-up (July 25, 2014)
Got this board to figure out if the Atom 8 core C2750 was any good.

Am running FreeNAS-9.2.1.6. which has gone fairly smooth so far.

I have had no issues with the board apart from the fans occasionally switching to "FULL-Throttle mode" and not going back to "smart mode" on their own. The BIOS settings do not appear to be altered or affected by this change. Shutting down the machine and rebooting will not fix it either but power cycling it a few times will get it to revert back to "smart mode". I have replaced the fans and the PSU in an attempt to stop this issue, after which the fans stayed on "smart mode" for about a week but now they have just gone full-throttle again. There are no events in the Event Log so I am having difficulties explaining the issue to myself.

This was my first time fiddling with IPMI. A problem I ran into with IPMI was that I changed the password for the IPMI admin account but when I tried to log on again the password was not what I thought I had set it to, resulting in me not being able to log on afterwards. Once the modified password has been saved, the admin user gets logged off and you cannot make any further modifications or revert without logging back on, which can be problematic if you somehow got the password wrong. That problem was fixed by downloading an IMPI config tool which runs in DOS (versions for other OS's exist as well) and allowed me to modify passwords and some other things without logging on to the IPMI interface. Afterwards I realised that it would have been smart to create a secondary account and get that to work before changing the admin password. It appears that the IMPI chip is not unique to this board or it's manufacturer so I imagine I could have had the same problem with a board from a different manufacturer.

As other reviews have said it does take a significant time to post, so there is probably a 30 second wait until you see anything on the display after powering it up.

I cannot see any reviews or complaints online by people who have had the same problem with the fans as I have, so I am leaning towards the explanation that my board is a little faulty. I am not certain whether I will get another one of these boards or whether I will wait for Asus and Gigabyte to come out with their C2550 or C2750 boards and perhaps give either of those a try.

Nice features, poor quality

Reviewed in the United States 🇺🇸 on May 28, 2014

EDIT: 4 years update - Now 3 stars
Board was replaced under RMA early last year due to the watchdog issue (watchdog was writing to flash every update, causing the memory to wear out). About a year in on the replacement board and the board just stopped working. IPMI still works properly and reports everything is good, power supply is putting out the correct voltages, but the board will not POST. It is effectively dead.

In the end I'm going to give this board 2 stars. It didn't necessarily outlast it's warranty, and the replacement board only lasted 1 year. Too many failures from a board that is supposed to be in a commercial server environment. I would have expected a board like this to last 5 years minimum.

=============================================
EDIT: ~9 month update - Now 4 stars
After fighting issues, I completely stopped using the 4x SATA ports on the 88SE9230 controller until September (my first opportunity to do any major updates).

I updated the BIOS and the firmware for the 88SE9230 controller and voila, no more issues. I have now been testing the 88SE9230 SATA ports for 5 months with random read/writes and have no issues to report.

As a side note, I do want to thank ASRock's technical support team for providing updates. It took them a while, but they did get the correct information to me.

Unfortunately, I didn't have the time to apply them for several months.

=============================================
Original review:

Major issues here: Extremely limited RAM support, SATA controller issues, need to disable several features for stability.

Memory: Most models on the Memory QVL are not available or are super-special order from the manufacturer. After calling Crucial, they have already discontinued 2 of the options on the list. PLEASE qualify more RAM!

Disable features: In order to get the board to remain stable (ie Not crash or cause Kernel panics at random) there are 2 options in the BIOS that need to be disabled. These are 1)CPU C State and 2)Speedstep.

SATA: This *BY FAR* the biggest issue. I've tried all of the BIOS version available on ASRock's website, the oldest is the most stable for SATA. During high I/O loads, the SATA interface tends to crash. With ver 1.80 BIOS, that happens after 5-20 minutes. With ver 1.50 BIOS that happens after 1-3 hours. This is a *GIANT* issue, as you cannot build/rebuild a RAID array without lots of I/O. No RAID makes this board effectively useless, since NAS appears to be it's designed purpose.

Still waiting to hear back from ASRock support (no phone support, email only). I'll give the benefit of the doubt, but will be returning this board if support is unresponsive.
