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

[octominer]

Overall very nice experiences from Octo products and their support.

Prices are very good and if you think the support you get vs. almost anything else in crypto business. 90% of crypto companies have awful websites, slow, buggy. Slow and bad customer service, Octo have good working website, 5/5 star customer service.

Im running currenctly ~250GPUs and some with octo (some not since they dont fit the board), some octo boards with case and some without but im thinking to get case to all of them since when i do quick math:

~230€ octo case you get fast setup, great airflow and easier to plan airflow since flow direction is straight and simple. It adds ~170€ to 8GPU rig price (50€ metal normal rig rack i pay here) but in long run i think its worth it (less heat, longer lifetime and less crashes to gpus).

Just my thoughts on their products and keep up the good work .

Nice, glad to hear you are happy with our motherboards and hardware. 
Out of interest, how is the temperature of the rigs that use our motherboards and cases compare to your open air rigs?

I've got two of these running WIN now, one a cryptonight rig with 8 MSI RX550 I was really nervous that the board wouldn't be able to handle the start up power but with bios mods it's sailing along. The other with 8 Galax 1050 TI the 1050 TI rig runs with the Octominer ATX power supply.

Both builds took under 15min including unboxing etc which is epic.

RX550 rig is getting stable 3960 H/s @ 411W at the wall from a coolermaster V850 and the cards are running ridiculously cool around 52-5 C which is only 20 or so C above ambient on a regular day here..

1050 TI is doing  4Mh/s Neoscrypt / 121Mh/s Eth @ 624W at the wall from Octominer's PSU with cards running nice and cool around 67-9 C which given the ambient temps here is brilliant.

I haven't done anything sexy just used rubber kids playmats, dumped them on tables and built the rigs right to the edge of that. The playmats are exactly the right thickness for two slot GPUS to support themselves on the table underneath with close to 0 droop. Ventilation from my rig room is just two overpowered stand fans sucking air out the window and bringing up cool air from downstairs.

This beats the everliving crap out of building junk/dinosaur rigs which I've been doing for ages.

That's great! Thanks for the feedback.
In general how's your experience with the Octominer motherboards compared to your previous rigs ?

They're more expensive in terms of outlay however, 15min 8 GPU builds including getting WIN/Ubuntu installs started there is an enormous saving on time. I've been buying used 2-4 slot complete machines and used everything from duct tape, to bailing wire, to hacksaw case mods to put them together and it's just not worth it.

The math works like this:

75$ For a used 2 slot PC with the works including a 500W PSU.
12$ For a decent riser and 1 or 2 molex - pcie converters.
2$ For a bamboo dish rack that holds up to 4 GPUs.

89$ Total.
 
So 356$ for the equivalent of an Octominer going by number of slots.

555$ For "Complete" Octominer set up 8Gb Ram 120Gb M2 1650W Atx.

Sure, it's roughly a 200$ price difference, however it's 3 less installs to do, it takes up a lot less space etc. You don't have to hacksaw and drill a crappy case to add a fan to it etc.

Yes, you can run scripts etc if everything is linux and if I were doing this full time I would be. However, at my hobby level with the Mrs running things when I'm not here, this makes an awful lot of sense and raises the pleasure level significantly.

THIS^^

The amount of time saved from the builds with the octominer case is huge. I bought 18 complete setups recently and I can tell you that going from the open rig concept with risers (PITA) to the octominer setup made things so much easier. Also I'm going more dense in my setup and needed a better way to control the air flow in my shed (12 X 16 X 8H with barntop). I have 450A service being installed this weekend and 42 Avalon 741's to setup along with 20 Avalon 841's.

Anyways thanks octominer for your great product and service. I'll be posting photos of the completed setup once its all said and done.

Hey Tim!

Thanks for the feedback!  Looking forward to the photos.

Here are the current photos. One call screwed up about 4 ft on their marks so we hit electrical line, internet and water while trenching. Had DEMCO guy quit during transformer install and took EATEL 4 days to get our internet back online. We still aren't done yet and it's been 5 days... So should have more updated pics on Mon/Tuesday hopefully unless some other crazy shit happens.

Also octominer I'm having issues with 14 of the SSD's onboard and 5 work as they should. Here is the scenario:
IF we lose power and get power back to the units the SSD isn't recognized on boot. The message I see is "Please press any key to boot and insert media to boot...." during this stage the SSD LED doesn't light up on the SSD UNTIL I press the power button OFF then ON. Then the SSD light comes on and boots as expected. If I do a CTRL+ALT+DEL the SSD is NOT recognized until I completely power off the MB with the switch and power it back on. Can you please help with this issue?

Thanks

What’s difference between octominer mobo and other mobo that looks just the same but without Octominer logo on fan - different bios and warranty? I see there’s Octominer logo on monitor when starting cpu but is there better bios or is there just the logo?

Hi!
There is no difference. We had a small batch come from the factory without the logos on the CPU cooler. Otherwise everything else is exactly the same.

The ones I see come brand new but they also don’t have the octominer warranty sticker on the motherboard - are these still Octominers?

At this moment its 15-20c less than open air rigs, problem with open air rigs is that there is no clear direction where the heat is going so when you have box like octominer case its much easier to plan airflow of unit/rooms also.

[CotyDlux]

Just put  a rig together today with an Octominer case and mobo. I'm impressed. temps are all around mid to high 50s with 5 rx480 cards installed. The airflow is really good for the Sapphire cards since the back end is open. Great combo IMO.

[CotyDlux]

Tim,
PM me your pvcy setting don't allow noobs to PM you. I live right down the street in Gonzales.

[FoolFully]

Issue I’m having with my octominer is after boot up there is loud asic type sound coming from cpu shroud that I must tap it in right spot for sound to stop.

One thing i noticed:

When you dont have monitor attached to vga port of octoboard and reboot device -> login with remote desktop like Anydesk, you will get black screen. Once monitor connected again and reboot it works OK. I guess no other solution than get VGA dummy / emulator

I was really considering some of these boards, but if this is the case they won't work for me...

I think that might be a software bug related to Anydesk. Otherwise our motherboards work fine for remote use also.
Usually best practice is to run a dedicated Linux based mining OS like HIVE OS , ETHOS or SMOS.

This board is awesome. After 15 days of working 8x RX550 mining monero Today I tried 12 GPU with port multiplier. I use 2 different kind port multipliers. Actually I think I can use other 2 free slots on multiplier for 14 GPU but I dont have free GPU at the moment. There is an order in a chaos if you can see it. Just joking. Its a test bed. Not final form. Also I wont run 12 gpu over 1 day. I will order more octominer board. I install HiveOS and Windows dual boot on MSATA SSD for future troubleshooting or bios mod. But its not good performance on Windows due CPU. I miss change to buy board with Pentium CPU. I hope you will sell it again.
But to be honest I think I will try non branded one for just a curiosity.

Glad to hear that you are happy with our motherboard.
The 12 GPU port multiplier rig looks pretty cool but kind of defeats the point of having a stable and riser free motherboard. 
Whats the cost of a port multiplier like that?

[NiklasFalk]

Whats the cost of a port multiplier like that?

There are two different typs in that image, both cheap. The one to the right is a card with 4 "usb" connections to 4 single risers, about $15-20 plus the cost of the risers.
The one on the left is a one "usb" to a card with 4 slots (and requires 5+12V on Molex no 3), costs $20-25, I have not had good luck with this type.

High pressure fans and controlled airflow (i.e the case) is the way to get control of things. Not as cheap up front as getting a bigger and bigger pile of sub-par stuff after constant upgrades.
But it is a journey up the ladder of experience. In the end, some convenience is worth the investment.

I got the octominer case but now need the fan controller. Is this fan controller available in US - not sure what to search on eBay?

Wow that was easy. I was quoted $19 so I paid in LTC and the total was like $18 something with free shipping. The only problem I had was copying address. I had to paste link in notepad so I could then type it and make sure it matched.

Thanks!

Can anyone help me to convert my Octominer so I can use Oculus rift. I’ve never had virtual reality system and have a few question to multipurpose my mining rig.
Is it better if I use all 8 gpu at same time or can I only use 1?
I want to do the high fidelity Rust virtual reality dance party so it tracks my movement with many sensors so is cpu and 8gb ram good enough?
