So, continuing:

One of the best ways to do fairly precise layout for drilling holes is to just have a printout done, and then centre-punch right through the printout.

Since this is fairly large, I wound up having it printed out at the local staples. $3.29 per page for 24x36" black-and-white prints.

Your every-day printer is *surprisingly * dimensionally accurate.

I laid out, punched, and drilled all the holes in the baseplate, plus laid-out, drilled + tapped holes in the 1/4" square bars.

Initial mockup went well, though I needed to order more screws.

Here's the power supply and one of the bus-bar mating assemblies installed as well. The other bus-bar connector isn't finished yet (the cables for that one were in use until just a little bit before the picture was taken).

The servers fit nice. They do hang out the end a fair bit, mostly because my rack is 28" deep, while the servers are ~34". I'm OK with this.

Sled carriers are installed in the rack here. The first set of support hoops don't have a top because I need to be able to angle the servers into the carrier a bit, because my server closet is literally a closet, and I don't have a full 34" from the front of the rack to the wall. It's super right in there.

Servers both installed and happy!

didn't see but do you plan to sell these? Also do you make a mount for them on their side so you can fit more of them in a single row?

This is actually the, more or less, complete idea I had - please praise me for my awesome MS Paint skills. These nodes have quick disconnect terminals that can hook into, what looks like, 1/16" or 1/8" copper bar, so if you're only hooking four of them together you could have a really neat setup that fits in about ~4u and uses the same power supply so added efficiency.

I guess you could do similar horizontally but I'd think there would be more complexity to it... this seems relatively straight-forward..

Hi... I am looking for a similar setup. Could you share a pic of your setup with PSU connection?
Bought a PSU from miners, it has a lot of GPU connectors, the connectors have a different keying, but I forced them into the midboard, just making sure that yellow wires are on 12V side and black wires on GND side. M/B draws 300W, so I made sure I used enough independent cables. Works for half a year now.

Any chance you have a pic of the specific PSU and a clearer pic of the orientation of the atx cables on the mid-board. I’m a bit of noob at this, so it’d really be a great help.

This looks like the Mid-board from the Quanta F06 Leopard if I’m not mistaken. I have the same breakout board in mine and I’ve been trying to use a HP DPS-800GB A PSU with a mining Breakout board, but I haven’t had any luck getting power to the motherboard.

the breakout board came with 6 to 8 (6+2) pin ATX connectors, and I’ve connected only the 8-pin header to the breakout board, but it looks like you have the two 4-pin connecters wired up as well. Are those required? Or is it sufficient to just wire the 8-pin connector? Any help is greatly appreciated!

This is no surprise, because these ones are not Winterfells, they self-identify as Leopard-DDR3.

No, they're not required for boot. I plugged them all so that 300W is spread among wires.
The orientation is simple: yellow to the one side (inner), black to the other side (outer). It is easy to see on the midboard areas were 12V and ground are connected. You only need 12V and GND to power up.

The motherboard is slow to boot. Also, if the CPU is not supporting DDR3 (most v3's don't), than no chance to boot up.

Ah, I see. I’ve been using two E5-2620 v3. For memory, I have two Kingston 4GB DDR3-1600/PC3-12800R ECC DIMMs.


On Intel’s ARK site, the E5-2620 v3 shows compatibility with “DDR4 1600/1866” but I haven’t seen any DDR4 DIMMs with speeds that low so I figure that DDR3-1600 would work. Am I incorrect in assuming that? I’ve seen on other forums that a E5-2678 v3 (which are similar to the 2680 v3) is what came from Quanta when delivered to Facebook. If you don’t mind me asking, what processor worked for you?

I apologize if this is a noob question, I am a beginner to all of this and would appreciate any help or suggestions!

Won't work.

DDR4 won't fit in DDR3 slots. You can't install DDR4 memory in this board. And if you use DDR3, the CPU should specifically support it. The list of such CPUs is kept secret by Intel, you can either try yourself or find reports on forums. Most of them are OEM versions not mentioned in Intel's datasheets. I got this list: E5-2678v3, E5-2629v3, E5-2649v3, E5-2669v3, E5-2696v3, E5-2686v3.

I use E5-2678v3 and am impressed by its performance (and price).

Okay, that makes sense now. I couldn’t find an official data sheet for the E5-2678 v3 or any cpu that supported DDR3 on Intel ARK for that matter. So I was a bit confused on how this DDR3 motherboard was compatible with V3 CPUs.

I’ll try and grab a E5-2678 v3 to test with.

Thanks for all your help! I really appreciate it.

It's amazing how you documented your findings. Great to see how BIOS in Serial Console works, so great!

I myself bought dual-node winterfell few week ago, everything seems working fine and the only issue I got is that vga output is intermittent. It outputs video for first boot but not after restart or shutdown and I need to manually press Power Off/Restart button to get vga working again. It happens both for Linux and Windows, do you have similar issue? Thanks in avanced!

My settings:
BIOS F03_3B11
UEFI boot HDD (disabled the rest)

p/s: so excited to know that winterfel server is still being used nowadays :D
