After viewing the datasheet I purchased the Wiwynn to use with 2660v2 chips. Unfortunately, they do not work. I contacted the seller and he said that it's due to an outdated BIOS, but as others have mentioned in this thread, they're impossible to find anywhere. I think the Quanta boards would actually support the v2s since it looks like the BIOS updates are obtainable. I might order the Quanta board to try it out, but has anyone here who updated to the latest BIOS tried them with the v2 chips?
Potential Deal: 2 x Dual 2011 nodes @$199, Quanta Openrack

Hi all,
Just finished reading these 21 pages of super useful info, thank you all
DonJon's solution of using HP PSUs and just soldering the 12v is really awesome, thank you for pics and the writeup.
I'm wondering if you guys think it's possible to run 1 node alone without the midplane?
Cheapest barebones rack I could find was $220 w/ shipping. For a single mobo @ $90 w/ shipping, I could accomplish the same goal, as long as it's possible to hack the connect and spoof the fans somehow. The datasheet pinouts for where the midplane connects to the motherboard shows some fan inputs to the mobo, as well as some "SMBUS" business. Considering I don't really need both mobos or the PSU included in the "usual" purchase, I'm thinking I could hack the midplane connector and just get the mobo by itself.
Thoughts?
Also, completely irrelevant, but I'm eyeing some "SAMSUNG 4GB 2RX4 PC3-10600R M393B5170FHO-CH9" RAM. I'm thinking I could throw 1 stick in every 4 slots (4 sticks total per node), to start out with. I've never touched server RAM, so is it even possible to use only 4? Or do every other (ie. 8 total) slots need to be filled per node?
Thanks in advance; n00b questions from a college kid

When setting up my machines, updating bios, and testing, i installed only two dimms. 1 for each processor.
Happy to report that the v2 chips indeed work on the Quanta boards after the BIOS update!
I was reading all 19 pages of the thread, and the links, at work today an saw the pics and info for the HP power supply mod, now I'm at home and can't seem to find it.... Could someone point me to the post please? Thanks!

In the event that not everyone is comfortable with hacking power supplies, or simply would prefer a premade solution I found that there are adapters available for the HP Common Slot power supplies. It seems that the PSUs are quite popular with *Coin miners and someone decided to fill a void and market a fairly turnkey solution.

Much cheaper eBay option:

EDIT: Oops, forgot to mention something.
I also found another adapter that was designed to power up to eight PCIe GPUs which I thougth may be of interest to someone.

That's great news. It's too bad that the Wywnn machines don't appear to have firmware available with support for the Ivy Bridge EP processors, even though their documentation statues otherwise, but it's good to hear that the Quanta boards will work with the more modern processors. I was reasonably confident of the support after reading the changelog included with the most recent firmware but I'm much more comfortable with third party confirmation.
Thanks.
Something just occurred to me. This thread was 21 pages long the other day but, as Klee said, it's now a mere 19 pages in length. Is it a common occurrence for threads to shrink on this forum? If posts were deleted it would explain why first Klee, and subsequently I was unable to locate the post(s) which brought the HP power supply possibility to light.
Well I do remember it was 21 pages earlier while I was at work, I was not logged in at work and am here at home so I thought it was because of that and did not think about it so I opened another browser and its only still 19 pages not 21 like before......
Both the power supply mods posts seem to be deleted. If anyone still looking for the mods, the PSU Used on second post was 750W Cs He Power Supply Kit, you can search B0025B0FAW in amazon for its page.
The first and third data pins were soldered together with a 300K register in between, assuming to start the psu (Same as atx power supply). And large planes on left were used as positive and negative connections.
Connection on the power mid-plane / fan unit was soldered with 3 positive and 3 negatives serially. (From first post)
Is this true? Who deleted it? Why? Without any attribution? Maybe another site might do that but NOT STH. I hope.
New guide for using third party PSU
Background:
Unlike desktops and other servers, the motherboard and fan/psu unit does not switch on/off the PSU directly. Even when the nodes are off, the PSU is still on. Powering the IPMI / Remote management i guess.
The default PSU provides 12V DC. Data pins are used for LED on the disk trays and load balancing current using AC/DC input to PCU. If you are not using DC backup source, you can ignore the load balance. If you want the tray leds, you can use hobby female jumper cables to supply 5 volts. If your new PSU provides backup source active signal you can use that at A2 pin with similar jumper cables. For normal usage, you can do without any use of the data pins.
More info on default PSU : http://www.opencompute.org/assets/download/Open_Compute_Project_700W_450W_Power_Supply_v1.0.pdf
You can get any 750W+ 12V Output PSU from ebay or amazon. You might want to review it first to see if it is noisy. Once you have it, you can see its specs to find the +ve, -ve pins and POWER_ON pin.
If you are okay with simple soldering, HP Common PSU are ideal.
For regular ATX PSU
Connect #14 in 20 Pin and #16 in 24 pin to any Ground pin to start the psu.
For Server Part:
Simple hack would be using Bent Car fuse Pins with hot-melt glue to firmly attach the wires. If some one has any experience using pins with insulator outside that might fit the receptor, please suggest.
If PSU supports on/off like HP Common Slots, you can also use the rocker switch from ebay ($2 for a dozen), with the register along one end. For regular ATX, you don't need a register.

OS Installation without graphics card
1. Install OS using different computer and plug in the hard disk to the node.

Tested with Ubuntu 16.04 Server. Use SSH to access and configure further. Before moving the hardisk, make sure the nic is setup. Was eno1 for the 1GbE and enp9s0 for the 10GbE.
If you see hard disk activity but can not connect, you can re-mount the hard disk on first computer and check the syslog for interface names or other errors.
2. Install using IPMIIf you see hard disk activity but can not connect, you can re-mount the hard disk on first computer and check the syslog for interface names or other errors.

Edit the grub command line on the installation USB to include GRUB_TERMINAL and GRUB_SERIAL_COMMAND.
Default username/password for SOL are USERID / PASSW0RD
Password has number 0 instead of O.
You might have to restart the nodes once connected over SOL to see BIOS and GRUB menu.
Above docs have full docs, here are few helpful commands:

If any one wants to print PCB for power adapter, this part number is compatible with PSU's connector. The original part needs to be ordered in bulk. This one can be purchased in small qty.

I have a difficult time imagining that there's some sort of sort of conspiracy going on here. I expect that there was a valid reason for STH to have deleted the posts in question.
Hi again,
Bought all my pieces for a single node. I got the Quanta version, and with a Radeon 5450 GPU I can boot up into BIOS setup successfully.
When I created a Win7 Pro 64-bit boot partition on a harddrive (made partition primary and active), and select it to boot from, the screen just goes blank and nothing happens.
I saw "BIOS Update" being thrown around, might that be an issue preventing Windows from booting? I can't seem to find any useful documentation on the BIOS update process. How do I update the BIOS? Can I do it through USB or is it more involved?
Thanks in advance!
