Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU)

[octominer]

Cool.  One thing I'm interested in and am going to test out with the one motherboard I ordered is cooling. 

Rather than getting a case with a bunch of fans, I'm wondering if an "open air rig" with a box fan in front (and maybe in back) would give enough airflow.  My idea is to get a metal rack (ie. one you can find off of amazon/lowes) and put several miners on the shelves.  Directly in front of the shelves would be a stack of box fans - one stacked on top of another. Will probably build a wooden frame so I can easily stack them and put them in a wooden rame.  On the back, thinking about having a bunch of box fans again, or just a big exhaust fan (the one I have right now in my basement is 3,000 CFM) to suck the hot air out.

If you have a box fan, would appreciate any tests you could do with the 1080tis and putting the box fan in front of the motherboard/GPUs on the highest fan setting.

I'm not opposed to buying a case with fans, just trying to figure out of there is an easier/cheaper way to cool a rig - especially running multiple rigs.

Or if you/anyone has any other thoughts, please let me now. 

I will be getting these 1080 TI's. Will post results when I get them

Sounds good. Open air rigs will work fine  if the cooling is designed properly and there is enough airflow.
We will be posting more testing results in February. We are currently designing an open air "rig" also for the motherboard, we will start shipping that in March.

Octominer can you provide some more details on this PSU? https://octominer.com/product/2200w-octominer-server-psu/

Didn't see much in the website for it.

Thanks.

Until the site is updated here's their reply when I asked via the site:

The server PSU is 90 PLUS Platinum rating with an efficiency rating of
93.1%. It does not have a breakout board, it already has 10x 6PIN cables
coming out.The server PSU has 2x 60MM fans that are high power and loud.
The server PSU is very efficient and powerful but loud.
We will update our website soon with the images and dimensions, all our
team is currently busy with making sure that the new batch of
motherboards arrive on time and everything gets shipped out before
Chinese New Year.

I think I'll grab one for my next rig, see how they compare to the unobtanium parallelminer 2400w PSUs.

If this 2000W PSU will have 8 pin(6+2) connectors it will be top option because most of GPU-s have 8 pin power connectors...

PSUs have 6 pin at their end then you can use either 6 or 6+2 cables

octominer do you know if your motherboard is compatible with Ethos mining operating system? I know if its not you can submit the data to the Ethos team and they can add it to next build?

Yes it is option but this make it more expensive than other options...

Works with ETHOS no issuees. I personally prefer HIVE OS and run my miners on that.

Octominer,

On your website I see you sell mSATA drives.  Is there an mSATA slot on the board somewhere that I'm not seeing?

[proteus7]

Octominer, are there any photos of the chassis? How many power supplies does it support? Is it rack mountable? (Includes rails?)
Thanks!

Yes, it does have an mSATA slot, it is between the second and third PCIe slot.

We will upload the chassis photos tomorrow. It can support up to 2 PSU , depending on the PSU size. Currently it does not have rails but we plan to add that feature in the future.

Almost at the end of the month so any update on when they will start shipping?

[hopfi2k]

May I ask again if board supports PXE booting?

Thanks,
Andy

Shipping for the next batch will happen between Feb 5th and 8th.
Only around 150 boards left right now for that batch, almost all sold out.

I will get back to you on that question.

[Kapz786]

octominer are you able to add the option to purchase the case without the fans or with the quieter fans?

I want to order but not keen on the loud Delta fans

[mr_blanket]

I'm certainly interested (and sick of low quality risers), but it all is about the 4U case for me. 

Once I get picture of the case and how the 2200 watt PSU fits, I will probably place an order today.

Thanks!
