My mobo is not posting. It beeps 5 times as i power on, but nothing after that.

Please help.

Hi, was wondering when the rest of the orders for the 4U case were going out? I placed it on Feb 3 (chassis, msata, RAM and 2200w ps).
Thanks, and Gong Xi Fa Cai!

Hey!
The remaining orders for the case will be sent out right after the Chinese New Year Holidays end.
Happy new year!

I'm up and running with 8 cards under windows with no issues.  I never did anything in the BIOS except tell it to boot from USB the first time to do the windows install.  I downloaded the latest ISO directly from Microsoft, stripped out all the bloat to make a light "miner" version.  I then installed into 120GB Msata from USB using the built in VGA port.  Once it was installed, I let it go out and grab all the latest updates.

I then installed a single GPU and installed the latest Nvidia drivers (all done with VGA monitor still connected to the mobo).  Once that was done, I shut down and added 7 more cards and started back up again.  It took Windows about 20 minutes to properly see and load the drivers for those additional 7 GPUs.  Once that was done, I installed Afterburner, Afterburner Remote Server and Awesome Miner Remote Agent.

Went into Awesome Miner on my workstation, added the Octominer, and away I went mining.  Very smooth from start to finish.

Hashing away with nice low temps despite running with no lid:



And some pics of the rig.  I'm running a 2400W Delta PSU temporarily until I decide what I want to put in it.  I'm also running 4 hybrid 1070's for right now since they needed a home and I'm still waiting on some other mobos to come in.  It will be converted to all air cards soon, but I didn't want to leave any cards sitting around not hashing.  

...



I'm overall pleased with the Octominer, but do have a few minor gripes as follows:

1. The silk screen showing the front panel pin-out is obscured by the mSATA device.
2. The polarity for the front panel HDD header is missing.
3. The Delta fans are nice 4 wire (PWM control), but both the RPM and PWM wires were cut off, leaving only GND and 12V.  It would have been nice if those wires had been left intact in case I wanted to ever use those fans in another application.  A 4-pin fan header to 2-pin Molex plug would have been ideal.
4. There is no provisionings for screwing down the Octominer server PSU within the "ATX PSU" space.

I know, very miner gripes, but I wanted to mention them.   The key thing is that the board itself is very stable and works well, even with Windows.  The board was able to to detect my Logitech USB Bluetooth dongle for my wireless keyboard and mouse, something that I cannot say was true with either my Onda nor Coloful mobos.

where did those good looking waterblocks come from?

they would work good on a four slot biostar  z170 mobo


To be on topic  this look like  a good setup  if noise is not an issue.

The deltas will cool well enough but it is more a warehouse build not a basement build

Thanks, tried all. After that contacted their support chat, seems like Mobo is dead, they will ship out another one after holidays on 25th Feb. Great support from octominer.

Anyone know the exact power requirements for the motherboard? The case only really seems to have mounting brackets for ATX form PSU's, and I've yet to find a PSU from a reliable manufacturer that has 10 pci power cables for 8 cards + 2 for the motherboard. Using multiple power supplies defeats the purpose of the 4u rack mount case, so I was hoping to power the motherboard with some combination of molex to 6 pin connectors. Is there a safe and electrically sound way to do that, or do I need to roll the dice with a lower quality PSU manufacturer?

Thanks, I don't know how I managed to overlook corsair. Is it safe to use a dual head cable to connect both motherboard slots, or 2 gpu's from one PSU outlet?

So this morning I took the time to move my 4 1080tis from biostar 12 GPU board (which was a pain to get all 4 cards working) to the octominer board.

It was very easy to get up and running and I'm impressed.  A little troubleshooting, but no pulling out my hair trying to figure out why the cards wouldn't work with risers.  Also, I didn't have to make any modifications to the octominer board bios before I started hashing.  Right now running Windows 10 with Awesome Miner, (using a SATA SSD) but might try hiveos sometime.

Only have 4 cards and left a space between them, but I could see it be quite tight with all 8 cards.

Would be interested in hearing folks that are using all 8 1080ti cards "open air" without a case - how are you getting rid of the heat? Right now I just have a box fan on top.

Here's a pic of my setup (pardon the mess)

it depends on which 1080 tis you are talking about. I have 6 1070 zotac minis and 2 1080 ti aus strix oc.

I have to run the fans on the 1080s at 70% and they stay under 70c. Running no external fans, but I do have a few extra case fans I might start running to lower the gpu fan RPMS.

[proteus7]

Can someone confirm that this is actually a 4u rack mount case, with a cover? From what I'm seeing, it appears to be too small for the cards + power cables and power supplies? (I ordered 1 server PSU and 1 atx PSU, was assuming both would fit.

[crazydane]

I moved cards around today in my Octominer.  I went from this config:

0 Zotac 1070 Mini
1 MSI 1070 Sea Hawk X (hybrid)
2 Nvidia 1070 FE
3 MSI 1070 Sea Hawk X (hybrid)
4 MSI 1070Ti Aero
5 EVGA 1070 FTW Hybrid
6 MSI 1070Ti Aero
7 EVGA 1070 FTW Hybrid

Which worked great with no issues.

My new config is:

0 Zotac 1070 Mini
1 Nvidia 1070 FE
2 Nvidia 1070 FE
3 EVGA 1070 SC ACX 3.0 (5173)
4 EVGA 1070 SC ACX 3.0 (5173)
5 EVGA 1070 SC ACX 3.0 (5173)
6 EVGA 1070 SC iCX (6173)
7 EVGA 1070 SC2 iCX (6573)

For the life of me, I can't get the EVGA SC 6173 working.  This GPU works fine in the rig I pulled it from.

The problem follows the card, not the slot.  I have moved the cards around, only the 6173 won't work.

I booted into Ubuntu 16.04 (nvOC), exact same issue.

So this is the trouble card:

https://www.techpowerup.com/gpudb/b3658/evga-gtx-1070-sc-acx-3-0

Anyone else run this card yet on the Octominer board?  Seems odd that it would not like this one card?

I dropped the 6173 into another rig I just build.  Works fine.

Go figure...

They were my only gripes as well.

The only other issue I had setting up was 5 short beeps and 1 long 3 short beeps.
I reinstalled the the ram and reset cmos and on the 5th time it worked.

I have had cards like that.  Mystery never solved I just moved them to a board they worked on.

Thanks, I don't know how I managed to overlook corsair. Is it safe to use a dual head cable to connect both motherboard slots, or 2 gpu's from one PSU outlet?

A single cable with two heads like the link I gave you has been used by me to do
A 1080ti at 200 watts.

And two 1070tis set to 110 watts each.

That would be 220 watts .

I am running the Corsair now with 7 1080tis set to 180 watts each.

The kwatt meter reads 1350 so far so good.


I have two eight slot boards but not this one.

So far the Corsair is good.

No, the motherboard is too wide to fit into a standard 19" rackmount case.   I'm working on some ideas to fabricate mounts for installing it length-wise.

Here it is running with 5 GTX 1070Tis:

That's a Zotac 1070 TI Amp Extreme?

Can you please post a pic from above? I wanna see the space between the GPUS.
I wanna know if you can put 8 Amp Extremes in there.

[Darknicks]

Made an unboxing if you guys are interested.

Sorry for the low production value. Never made a YouTube video before. 😁

Thanks a lot for the video! It was great!

Question: where did you buy those PCI-E splitters for the cards? And what brands do you recommend?

The Amp Extreme covers up the next PCI slot.
