Topic: Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU) - page 20. (Read 35234 times)

Is there a wireless adapter that is plug and play with Hive OS - what’s a good one to get?

I just sent you a pm with a tracing + measurements for the mounting holes.

Just wanted to share, I got the Kingsand 120GB mSATA SSD together with mobo and ram. The SSD has very prematurely died after 4 days of use.

I like the Octominer B8PLUS, I added it to my reference list of motherboards with 8+ PCIe slots:

The B8PLUS has the slots spaced by 45mm (as I read on the website), and I wish it was 50mm like the ZRTK-21613 & ZRTD-101. But I guess you can really do that only if the designers had saved space by mounting the CPU/RAM/SSD on a vertical card like ZRT did....

Octominer, how long have you guys been in business? I mean the "SHENZHEN IH SUCCESS LTD" entity? Did you guys form the company recently just to target the mining market?

RIP my Amp Extremes...
Thanks a lot for the pic! I really appreciate it.
Off topic: Do you use Windows, SMOS or HiveOS? I use HiveOS.
I'm wondering what's the best config for the AMP Extreme (Core, Mem and PL).

The Amp Extreme covers up the next PCI slot.

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.

Made an unboxing if you guys are interested.

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

Here it is running with 5 GTX 1070Tis:

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.

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?

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:

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...

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.
