Intel Mini-ITX Atom 8-core Hardware Build Recipe Available Here

trumee

I have 3 Evercool 40mmX15mm PWM fans installed with 16GB (2x8GB). The fans are loud at boot, but then settle down to a whisper quiet 3000rpm. Its funny the DIMMA1 is 8 degrees Celsius cooler than DIMMB1 because DIMMA1 is under a fan.

Can you point to the website where these fans are available?

The fans from mini-box are very load.

Evercool EC4015 PWM from Directron. Keep in mind the fans are 15mm thick compared to the ones from mini-box which are only 10mm. So there is enough clearance using the bracket that puts the fans over the DIMMA slots. However, for the front fan, you will need to mount the fan on the external side where the front USB ports are located.

You will also need standard PC fan screws since the screws that come with the fans will not work.

These fans RPM ranges from 3000+-25% to 10,000+-10%. Looks like the low end has a wider variance, but they are still pretty quiet. At boot time, the fan will be full throttle and will sound like jet engines (true server class hardware) so if your router ever gets real hot, these fans will definitely let you know it.

HI,

Question about the power supply, I have a 12V5A power adapter, if I use the 4-pin DC power connector and 120W Module, Will that adapter work?

I will say that I am thoroughly unsatisfied with either pfSense and/or this hardware.

Using just the initial config, my box will lose its ability to acquire a dhcp lease from my cable modem, a Motorola SB6141, showing a link of 0.0.0.0. If I power cycle, and wire direct with my PC, I get a working address. PfSense was up for only 2 days at a time if that on 2 separate occasions. Tried other patch cables as well. May go back to my ddwrt box as it works much more consistent.

The most recent fix was to clone an unused MAC address for the wan, but that no longer works either.

Frustrated as this should have much more potential.

Also, it seems that many times the unit times out when making changes within pfsense, along with the inability for LAN clients to be pushed my choice of DNS servers. If I instead use the DNS resolver for this, clients show as though my choices are available, but they still only use my PIA VPN DNS. Weird behavior IMO.

Note: my pfsense box will shortly (~5 seconds) acquire a default IP of 192.168.100.10 from the Motorola SB6141, but then be assigned 0.0.0.0. It should move on from the internal DHCP to one assigned by my provider (comcast) which is usually 72.xxx.xxx.xxx

Sir Loin

I remember I had a similar problem, my pfsense router was not getting an IP from my Comcast cable modem. I am not sure what was wrong. To debug, I connected a LCD monitor to the video out. It was displaying "Igb3: Could not setup receive structures". I did the below, and that error was gone, and I got an IP from my cable modem. Everything has been working fine since then.

@Sir:

BTW, I had this error from the VGA output:
Igb3: Could not setup receive structures
I needed to do this below to get the system to work. It is from https://doc.pfsense.org/index.php/Tuning_and_Troubleshooting_Network_Cards
Intel igb(4) and em(4) Cards

Certain intel igb cards, especially multi-port cards, can very easily exhaust mbufs and cause kernel panics, especially on amd64. The following tweak will prevent this from being an issue:
In /boot/loader.conf.local - Add the following (or create the file if it does not exist):
kern.ipc.nmbclusters="1000000"
That will increase the amount of network memory buffers, allowing the driver enough headroom for its optimal operation.
To avoid this, only enable WAN and LAN during setup, then go to the shell to create the file (if it isn't there already) and edit it. I went to the shell (use VGA out or IPMI) and downloaded nano editor (I don't use VI, which is built in already).
pkg_add -r ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/i386/packages-8.1-release/Latest/nano.tbz  
pkg is not part of pfsense. Follow the steps in this link to bootstrap pkg on pfsense:

^ Tried that on a fresh install, WAN will only get DHCP address from a fresh install, but not consistent at that.

Either way, I will not thread jack my problem here. Need to do more troubleshooting.

Got pfSense 2.2.4 installed and running on my Supermicro A1SRi-2758F in the M350 mini-ITX enclosure.

Here is my final configuration:

Supermicro A1SRi-2758F
Samsung EVO 120GB SSD
Kingston KVR16LSE11 8GB (x2)
Mini-box M350 enclosure with 2nd hard drive mounting bracket
150w AC-DC Power Adapter, 12v 12.5A
Evercool EC4015SH12BP 4-Pin PWM Fan, 40x40x15mm (x3)

The firewall is connected to my Motorola SB6141 cable modem with a Comcast 125Mbps/12Mbps broadband. I did have to set the kern.ipc.nmbclusters=512000 to get rid of the Igb3: Could not setup receive structures error.

So far, everything is stable and working better than I anticipated. Coming from dd-wrt, pfSense is much more intuitive and more responsive. When I ran MemTest86 with all 8 cores, the 3 PWM fans spun at 7500rpm to keep the system in the mid 40C. In normal state, the fans spin down to 3300rpm and all is quiet.

Now I will be waiting for my fiber gigabit to become available.

On what kind of media was you installing pfsense.
mSATA, SSD, HDD, SATA-DOM, SSD-DOM, USB Stick,…

Oops, I forgot to specify that in my final configuration. I used a Samsung EVO 120 GB SSD connected to the SATA3 port.

Anyone know if it is recommended to do a full install on a USB 3.0 flash drive? I would prefer to have gone this route for fan location reason on the M350 enclosure.

You can safely use NanoBSD install from a USB2 flash drive.

On an USB Stick I would prefer to install the Memstick NanoBSD version.

But with an SSD you are really able to do a full install as you have enough space for all
as I see it right!

And if you want to go with an internally other drive for the most mainboards from Supermicro
are some SSD-DOM or SATA-DOMs out, that is then more something like an install medium
and not even outside plugged in as an USB Stick.

Wow, go with it, this would be a really fast pfSense box as I see it right!

Enable the TRIM support in pfSense if not automatically done during the installation
Enable PowerD "high adaptive"

The RAM I would try out as 2 x 4 GB or 2 x 8 GB ECC RAM and not only one module

perhaps if you go with 2 x 8 GB ECC RAM I would try up to tune the mbufs numbers

But all in all this is a very fast machine and you will be happy with it as I see it right!

I went with 1x 8GB stick of RAM for now so when I upgrade later I won't have to replace 2x 4GB sticks. I can just buy 1 additional 8GB.

This can be really better as I see it right, perhaps others won´t consider
but having much RAM inside a machine was never a false.

This cable will not work with the motherboard (I made the same mistake) because you need a Female 4-Pin Molex. This cable is a Male 4-Pin Molex.

Here is the correct SATA Power Cable.

That sucks! Thanks for catching that for me.

I did include a link to the correct cable in the OP. Good luck.

Yeah, I just didn't realize I ordered a male when I ordered it on newegg. Oh well, it was only a couple bucks!

dopey

i just purchased this build (from amazon and mini-box) with a few minor tweaks (different 4 pin extension cable).

Thanks for doing all the research and providing it.

Unfortunately the power brick is out of stock at mini-box for a couple of weeks so I'll have to wait a bit before being able to fully test everything, but still, this will be a fun nice replacement for my current dd-wrt unit.
