Hi there crypto experts,

Recently i've been experimenting with the new B250 Mining Expert Motherboard. Untill now the maximum number of cards you can run on the board is 16. This setup needs 8x AMD GPU and 8x the Nvidea P106 card.
I've been able to run a maximum of 13 AMD gpu's on the board. When i plug in 14th card the motherboard doesn't show any HDMI video output anymore, the cards do get power & fan's run.
Asus promised to deliver a driver update before the end of december 2017, the driver should enable the use of 19 AMD GPU's on the board.


Does anyone has any news or also experimented with the MOBO, let us know what you think! We want to get the 19 cards running asap.


(The PCIe Slot State Detection is REALLY GOOD  ;D )

BBT has run a number of live streams using the board. He was able to run 21 cards in Windows 10 using the latest Crimson Relive drivers and PCI-E splitters.

From his testing:

• 19+ GPU rig is possible in Windows 10
• A maximum of 13 AMD cards are supported
• AMD Drivers 17.10.2 required for more than 8+ AMDs
• Nvidia P106 mining cards are required for more than 13 cards

Coyn,

You might want to take a look at "Bits Be Trippin" YouTube channel https://www.youtube.com/BitsBeTrippin and there Website BitsBeTrippin.com

BBT Carter took 3 stabs at the B250 and concluded with VLOG #65 with 21 GPUs.  Videos are a little long but informative

I hope this helps

Thanks for the tips guys!
I've watched the video's, but if i'm right he does not use AMD GPU but a mix of both.

Still my point, drivers not yet here for 19 AMD cards.

 Among the 2 or 3 other threads that already exist about this motherboard.

But from what I have contemplating about getting one of these boards and maxxing it out with the 19 gpu after this firmaware upgrade,
Wouldn't overload the board at some point with it and all it's components running 24/7?
 :-[

No, it depends on many things, eth mining uses no cpu power whatsoever, equihash on the other side does and it requires a little more powerful cpu other than a celeron.

Does anybody know if this motherboard already supports 19 amd cards?

I am running 17 GPUs: 5 P106s, 6 1070s, 6 1060s... Win 10
I just ordered 1050s because of the cost of 1060s and 1070s.  I need one more P106 to get to 19 GPUs. 

ETH does use CPU - just not very much of it unless you're doing DAG file creation on the CPU like older Genoil versions, and even then it doesn't use a lot for long.

Equihash seems to depend on the miner version - but generally doesn't use much CPU either.

No, the board does NOT support the use of more than 13 "non-minining-specific" cards of one brand even under LINUX - ASUS did something weird in the bios to limit it for no apparent reason I can see.

Would it be possible to have 13 AMD gpus and 6 Standard Nvidia gpus or do you absolutely need the mining specific nvidia gpus?  I was wondering if as long as the other 6 were not AMD if it would work

it won't even POST with 14 GPUs connected.

Well it will, it's just that the 14th gpu needs to be a mining specific card liek the p102 or p106 .. I was wondering if it was a mining card requirement or if you could just use a any nvidia cards to supplement 13 amd gpus' on that board

you see that is the thing, why only p106, p104 or p102? why not amd mining cards like rx 470? why only nvidia mining cards?

because Pxxx cards don't have display outputs. they are not GPUs but just some PCIe expansion boards from motherboard's point of view.

The asus rx 470 mining card has "Interface: DVI Output : Yes x 1 (Native) (DVI-D)", so it is all bound by display output it seems.

Seems this thread is related to my small question even it is one month old inactive.


My question is, is it required to have 13 AMD gpu? How about 13 standard NVIDIA GPU or any maximum number of standard NVIDIA GPU supported?

Interesting point. Skipped my mind that rx470 mining editions are still mining GPUs. Has anyone tried if they would work towards building a 19-GPU rig? These days it seems like power consumption is key to staying profitable. I would love to consolidate some rigs and build 19 or eve 21-GPU builds.

not sure about 13 AMD or NVIDIA cards, maybe there are some driver limitations, but 12 cards work fine.

you can't use more than 13 cards with display outputs on this MB, so no, 14+ RX470s Mining Edition won't work, period. sorry to disappoint you, bro.

Hallo!
Ich bin neu hier bzw. ob ich richtig bin.

Ich möchte gerne ein Rig von 9 auf 11 rx vega 64 lc erweitern. Es funktioniert bei mir nicht. 9Gpus laufen ohne Problem!

Konfiguration:
Asus b250
24 gbram
PSU 2x 2000w

Win 10
Devcon
OverdriveTool,
SRBminer bzw StakXMR

Why do you need to increase the number of GPU? What do you want to achieve? Saving the cost of rig? It doesn't. A large rig will cost more than a few rigs of 6 GPU. In case of equipment failure you will have a large amount of GPU. My opinion is that the policy of increasing the number of the GPU is a mistake.

Windows 10 der Adrenalin Treiber bzw SRBminer erkennt alle GPU.

Ich dachte es wäre genug Platz auf dem Rig.
Sobald ich Nummer 10 einschalte zieht er Leine und startet neu.

hi everyone!  know this is a old thread but looking for advise regarding running 10 AMD 5700 on B250 mining expert. currently running with no issues 7 GPU with 6 GPU on 1st power slot(A) and additional 1 GPU on power slot(B) wanted to add 3 more 5700 on slot(B)

thanks for any advice!!

Update the mother board bios and you can add up-to 14 AMD GPUs.

Currently I have 14, mix of 570, 580, and 5700 XT.

7 in A row(580 n 570)
4 in B row(570)
3 in C row(5700 XTs)

and what version of bios are you running?

latest version that's there on ASUS website, it's Version 1208

How many power supplies are you using ? Is it stable ? Regards

I like making my rigs look cleaner as ever, using more than 14 gpu in a single motherboard will require more a s single powerpack, that's going to bring alot of wires laying around, not going to look good, IMO, I had this motherboard but my cards isn't even up to 16

im running 10 5700 on this board with zero issues/rock solid, actually wouldn't hesitate buying another for the price i got it at($48)  using 2 power supply slot A+C and Ubit risers with 1x8gig ram and pentium G4500
