Topic: Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU) - page 3. (Read 35292 times)

Hello, dear octominer and it's customers.
...
resolved

Will the new boards come with a new/improved CPU?

@octominer really looking forward for  this  9 gpu board ...will love to have them crunching with GPU'S for BTC...go octominer !!

Pair this new motherboard with 9 Rx Vega 64 and see a really great profit daily, up to more than 2 mBTC , or about 56 mBTC monthly, that is something I may tell my colleagues to buy one if they agree with me to sell the RX 5 series and to upgrade to Vegas. As long as there will be developers which will fork away their coins from ASICS Gpu-mining will never be dead.

Not dead at all. We are currently developing bespoke mining solutions for multiple big GPU mining farms in USA, Europe and Canada.

Awesome! Not that i need it but glad to see that crypto development isn't dead 

OK OK 
Small sneek peek pic of our upcoming 9 slot motherboard.

Give us at least some details! And what about EU supply? 

NEW RIGS AND MOTHERBOARD COMING SOON! STAY TUNED!

I assume he's referring to the fact that there are now equihash and ethash asics available on the market, which make gpu mining unprofitable for equihash and is severely hampering profitability for the remaining gpu-mineable algorithms.  Couple that with ETH likely going proof-of-stake and we may be in for a dark winter of gpu mining.  But you never know in crypto...

Can you elaborate more on your statement that GPU mining is almost about to exit?

Thanks.

Now running 6 cards with CSM disable, so all is good now (I could pull 2 cards out of another rig, but I'll just get 2 more to fill the chassis)!  Thanks Octominer for the tips!

I was able to enable 2048 aperture with CSM on.  

I couldn't get back into the bios after turning video to UEFI on VGA or a single card with HDMI, as turning off CSM complained about this and trying again after a reboot.  I was able to see a new error in device manager akin to error 12 disable another device, and that appears to the internet to be more than likely a bios setting.  Ended up doing yet another factory reset with the jumper, and was able to get VGA UEFI then back into the bios to disable CSM.

Win is reinstalling now after CSM disable, wish me luck.  Original problem is that I can't get past 4 1060's without pain.

There is plenty of reviews within this thread pretty much all positive. As far as I know there are know BIOS updates but to be fair there hasn't been a need to

Hello!! Looks good! Are there any reviews or reviews?  Does anyone know if they plan to support the BIOS? Thanks.

I disabled CSM in order to enable 2048 aperture size (4G decoding). But then I am unable to boot from HiveOS as this is Legacy Only.

Is there a way to enable 4G decoding with CSM? Or this not required for Linux distros. is it windows only?

Thanks!

No, I didn't try HiveOS. Now, the rigs are very stable and powerful, I don't want to experiment now as the thing is working without issues. Experimenting with something that i have 0 experience with could give me big downtime so there is no reason to try it now.

I am running 7x Vega for 2 reasons:

1) The power supply output is 1200W and 7 Vegas fit this but 8 do not (maybe cryptonight Heavy could do but I want to be flexible, I work on the drilling rig 28 days on/off and need total reliability and flexibility when I am away)

2) Power distribution board has 17 ports, I am using 14 ports for Vegas and 3 ports for motherboard. I never really measured the amperes through these cables, it can probably work with 1 cable, but I never bothered

If any of your clients have questions, you can always PM me here on the forum and I will try to provide answers.

These motherboards work fantastic with blower style cards like reference Vega, as there is no need for additional fans. I just plug the rig into custom made air duct and all hot air is exhausted direct out of the room. It is so easy to cool, unlike aftermarket coolers which require incredible airflows.

The BIOS of these motherboard is so complicated for me, I can't really understand anything, there are options that I have never seen on normal PC motherboards. It is not required anyway as the motherboard worked straight away, but surely, it is tempting

Hi ninjacoins,
it depends if the Vega is 56 or 64, the rigs are mixed with random number of each - each rig has 7x vega and HP DPS-1200FB server power supply, and power consumption at the plug is 1270-1350W.

I just ordered PLATINUM server power supplies that I got for great price on ebay, i hope I will drop the consumption by 100W on each rig by replacing all PSU, I calculated I will return the price of power supply in 90 days and have spare power supplies if something goes wrong, I will update here on monday when they arrive

Nice VEGA setup! Don't see too many of those.
Have you also tried running the VEGAs in HIVE OS ? It's a great Linux based mining OS and supports VEGAs also now. I haven't tested it myself with VEGAs.
Also, why are you running with 7 GPU instead of 8 ? 

GPU prices change daily. Current price for a 8x P104 rig based on Octominer B8PLUS motherboard and together with case, 4GB ram and 60GB SSD is 4050USD with DHL shipping & insurance included. Delivery time is around 7 days.
This rig gets 322-330 MH/S on ETH at 120-130W per GPU, total rig power consumption is around 1100-1150W.
