SuperMicro A1SAI-2750F / C2000 SoC / C2000 Network Controller

If you get reboots, can also be bad ram, bad capacitors for the ram or a weak capacitor anywhere in the mobo… Power flickers also.
MBUF can do it sometimes, but never did with mine. Just sort of made things not work well when MBUF became exhausted.
Seems like maybe a hardware problem or perhaps some BIOS issue.
Try running a RAM test.
Or boot into linux on that machine and run prime95...
Maybe its something as simple as low volt setting for memory on the board?

It reboots idling in Ubuntu booted off USB. I'm going to try MemTest86+ and see if that has the same issues. If it does, perhaps ram, otherwise, I suspect the mobo itself. To be fair, I couldn't get the board to post using the DIMMs closest to the CPU. I had to use the DIMMs furthest away (won on each side)
-
Probably a bad memory slot or a bad memory capacitor…
I've had exactly the same problem as you before.
With a completely non-working slot, I think simply bad slot.
With intermittent failure I suspect capacitor.
Either way, fix is same. Swap out the board.
P.S. Its a damn nice board. I'm envious.
-
I know this probably needs not be said, but when testing RAM, if possible, use only 1 stick. Test it in each slot.
Then the other stick. Test it in each slot.
Then together.
Otherwise you might chase your tail for hours or days.

You didn't like Atom boards. Nice to see you changed your mind :-)
Cheers.

Well - I do actually like atom boards when they are used within reason. All atoms are not created equal.
I have 1 in a netbook that has 2 cores but I'm not running vmware and 6 VM servers on it.
I use a 4 core atom as hardware pfsense server.
This board here is a beast compared to old atoms. 8 cores and on par with my old Intel quad core extreme.
So, yeah - now you have to qualify statements about atoms.
I don't care what name they gave that cpu or board of yours. Its clearly much better spec than an n2800.
The guys here has an n2700 netbook and 1GB of ram, but seems like he intends to use it the same way I use my 8 core AMDs….

When I'm talking about getting carried away with what can be done with an atom reliably, it this sort of thing I'm talking about.
Yours isn't even in the same league - I want one.

Yep, appreciate the responses! I've RMAd the board and have a new one coming from Amazon. I was thoroughly surprised when I stumbled across that board - "Atom" I feel, is now an inaccurate (based on its history) name for these new generation CPUs :P
FWIW, this is preparation for an upcoming move / upgrade in home lab space. This will become my dedicated GW and Suricata appliance. On a 150x150 connection, I needed a little more oomph than my Atom D525.

I have a few VMs running on a machine thats chewing 125 watts all the time…
Its a super reliable machine with a heat sink the size of my thigh.
I'd gladly replace it with that board you have there when that old one fails.
That might be a very long time though - Its all solid capacitors, top of the line board and PSU.
But if its struck by lightening (it happens) I will be buying me one like yours.
Let me know how well it manages temperature please?
I'd love a powerful fanless solution that didn't run hot or throttle CPU to manage heat.

Here's what I was running until the powerstrip I plugged into my PDU blew up and fried it.
Supermicro SuperChassis CSE-503L-200B 1U
Supermicro X7SPA-HF-D525 Motherboard
4GB 800MHz DDR3 Non-ECC CL6 SODIMM (2x 2GB Twigs)Optional:
PCI-E Express Riser Card with Flexible Cable
PCI-E 1, 2, or 4 port NIC (I had a 2 port INTEL PRO sitting around)
Price Tag: ~$400 shipped, ~$450 shipped with extra nic and riser
Note: At least that was the pricetag about two years ago, no idea what it is now (this was copy-pasted from a writeup I did at the time of build)It sucked about 20 watts, was silent, and temps were about +10F above ambient at the CPU. The D525 isn't all that splended a processor though… it's pretty weeny. Currently I'm running a Dell PowerEdge R210 (i3 550 w/ 4gigs ram) but for sitting in my living room, it's too loud. It draws significantly more power than the Atom board :P
I'll be out of town the next few days, but the replacement from Amazon should be here Monday. Once I get home and get it up and running, I'll let you know temps and performance. I run 5 IPSec tunnels that I can shove data down, too, so we can actually give a little work to the SoC ;P
On an unrelated note, my R610 is awesome as a Virt server. It's completely reasonable in terms of decibels and you can pick them up fairly cheap on ebay. Note: It's a full-depth 1u, so don't expect it to rack properly (see: at all) in anything other than a full-depth rack (eg: at least a half-height). You can hear it, but it's .. pretty damn quiet, especially for the power that it touts. With the majority of my VMs running, I'm seeing about 200 watts being pulled (CPU Usage averaging 30%) at the plug.
To be fair, I keep my house around 70F. Grew up in the north - the cold is in my veins :P

If it was up to me, every motherboard manufacturer would be crossed off my list and only supermicro would be left. Quality aside, supermicro is the supplier for ixsystems. Look that name up if you are interested in what they do (hint: extremely involved with *bsd).
That being said, supermicros are notoriously "stubborn" when it comes to memory. Make sure you only use memory that is on the tested RAM list. Never had a problem with a supermicro board, that wasn't traced back to a memory issue. I've had one particular scenario where a C2SEA (typed that without even looking it up, that's how much I like supermicro boards) simply refused to use any other memory, except a specific model on their tested list. Even when the untested memory used the same chips as a tested module. Tested the "faulty" modules numerous times in other systems (not supermicro), all of them are fine. I'm even still using a pair of the "faulty" modules it in a different system for the past 2 years.

"every"??? You don't know what you're talking about.

OP probably used non-ECC DDR3 SO-DIMMs in an effort to save money.
Oh, and iXsystems uses the ASRock mobo for their miniNAS product.
If you don't know enough to go off the "recommended/tested" memory list, then don't. If you do, it's all on you anyway.

Can't we all just get along…. (reaching for vodka)
Would using the wrong spec ram work at all?
Hmmm. Maybe he will tell us what he used.
I'll wait and see.

Supermicro and others all build based on "reference designs" produced by Intel / AMD / …
They modify these designs, some more than others, in an effort to gain advantage in the market (features / price). Most low-end PC mobos then go through a process where components (Rs & Cs) are shaved off the design until design will no longer pass end-of-line 'margin' tests.
This is one of the many reasons that cheap Chinese manufacturers that some in the community cheer so loudly produce hardware that sucks so badly. "Dude, I built a pfSense box for $99!" is so 1996.
Supermicro stays on a somewhat more conservative path with this, but there are others. This is especially true if you start dealing directly with the firms that do the original design engineering for Intel / AMD / ...
You'll never guess who did the original design work for "Mohan Peak" (the original Avoton/Rangeley design). There is a reason I've been so solid on the C2000 series SoCs here for the past year.
RCC-VE is expressly a cost-reduction effort on Mohan Peak.
Edit: iXsystems is a good company, and knows a lot about FreeBSD. I have many friends there. Supermicro is not their sole supplier.

It could have been a bad board, too.
Some C2000 designs have been modified to use non-ECC ram. It's not really a requirement unless you're doing storage.

So we shouldn't choose supermicro boards, because they are based on reference designs. The fact that supermicro supplies each and every one of the ixsystems' systems is irrelevant. And ixsystem's involvement with freebsd (and PC-BSD and FreeNAS) doesn't add any weight to the argument as to why go with a supermicro board instead of a different vendor.
OK, got it. Next time I'll go with a mobo manufacturer that does absolutely no testing with freebsd and cross my fingers hoping it will work.
-
I've never touched one of these 8 core boards. I like what I see though.
Which ever one of my machines dies first will get replaced with something like this.
-
My perhaps silly impression is that time, more than anything determines compatibility of boards and features with BSD and linux.
Not so much who is making the board.
Thats why I usually opt for older designs these days if I'm straight hardware with no hypervisor.
Who makes the board more affects quality, durability and features.
Seems to me anyway.

What? Not what I said at all.

I'm expressly stating that there are others.
We carry Supermicro boards.

The situation is not as bad as it was.
these days it's mostly about laptops and esoteric hardware.
FreeBSD finally has a current, 100% supported out of the box laptop.Some SoC vendors won't support FreeBSD.
