ASUS B250 Mining Expert MB - 19 Cards!

[betaminer]

I was reading something about PCI lane capability of CPUs... might be that causes limitation of 13 GPUS on the board?

[Bigdrago]

I think it never will be support 19 normal gpus.
Amd have never said that.
You have to combine it with p106 or p104 which normal people cant buy.

No, mining cards like p106 work and they use the pci lanes.

Ok, but the question is, i can have 11 normal nvidia gpu and 8 p106 or not???

Dont seem so. Seems u can have 11 amd and 8 p106 with the latest amd drivers.

 If you use risers that have the USB cable come straight out, clearance is not an issue at all.
 Right-angle risers you have to use in the "closest to the power connection" slots if you are going to use more than one riser per row. or you get cable interference that can make reliable seating of the riser "interface board" problematic.

 There should be no performance difference between the slots - try swapping your risers around to see if the issue follows the board.
 I've had issues where a "performance difference" turned out to be a marginal USB cable, and just replacing the cable with a better cable CURED the issue.

I have risers that go straight out so that should not be an issue, thanks.

there should indeed be no performance difference between slots but the reality is that I do have differences. I contacted Asrock and they suggested to return the motherboard. I have tried the low performing slots with other gpu, risers, cables, ... same result. I have some well performing ones so it was easy to test the same hardware on the faulty pcie slots. Strange but now it will cost me more money waiting for a new motherboard rather than buying a new one (I make more than 50$/day with my rig so anything above 4 days waiting is wasting money)

If I have 8 GPUs and 2 PSUs, can I connect 4 on Channel A and 4 on Channel B to spread the PSU load out?
Is it a must to fully utilize all 7 PCIe on Channel A before I can move onto Channel B?

[QuintLeo]

You can spread them out.

 I have 3 on A 3 on B on my rig right now, with 2 PS

[pepcox]

Am I able to connect 18 cards with configuration: 12x GTX 1060 6G GPUs ant 6x MINING P106 6G ? Or it need to be mix of AMD's and Nvidia's cards. If this is the only way what ratio between count of AMD and Nvidia card should I choose ?

On Windows v1709 I believe the limit on the Asus B250 mining expert is 8 Nvidia + 11 P106 and 13 AMD + 6 P106. On Linux you should be able to run 13 cards of either AMD/Nvidia + 6 P106.

Thanks! With this mobo can I stick with using the onboard HDMI port for my display monitor?
I noticed on some video they connect it to one of the GPU?

If you have enabled IGPU then you can use onboard HDMI port, if not then plug it in the first GPU you have installed.

Asus replies to me today:

"There should be no need for update, this board should support 19 cards already. To run more than 8 AMD cards, you will need AMD Radeon Software Crimson ReLive Edition 17.10.2 driver. Please download this from AMD website. For full 19 cards, for system stability we recommend mix of AMD and NVidia cards, refer to manual page 1-9 onward for details."

So. Hard to say if it is the mb or os that is only capable of 13 gpus.

[klintistwood]

I'm having a hard time finding a shop in Europe where this motherboard is available. Have you got some links?

I was also wondering if the motherboard had to be powered by ALL 24 pin connectors or if 3 molex + 1x 24 pin is enough?

I bet it was some clueless blonde from the support team who is not aware of any nuances and only checked the manual with one eye and gave you such "help".

You don't need any OS just to start the motherboard. It does not start with 14 ordinary GPUs.

You don't need to use the 4-pin molex connectors on the motherboard when using powered risers. They are only there for the few people that may still use ribbon unpowered risers.

I hope asus sort out this problem Q1.

So why dont we all use unpowered risers when we can get power from the pci-e slots?

I really wish people that did not own this motherboard, and are not using it with at least 12 GPU, would stop posting their hypothetical concepts as if they are truth, even if you read what you are regurgitating directly from the Asus B250- Mining Expert PDF, You may not be correct and are spreading misinformation,

 A certain configuration within the Asus PDF manual may work, but the truth is that many others work as well, so unless you are actually experimenting with this board, rehashing things you read on line, is not helping this thread...

But actually spreading misinformation that will waste new users time to trouble shoot, and figure out why,

and Yes I am using the Asus B250 with 12 EVGA GTX 1070 TI SC Hybrids, and it has been working splendid, once I figured out my proper Overclock settings within "Simple Miner"

I am currently running two power supplies, Both EVGA, first being a 1600T2, second being a 1000T2,

I really hope this did not come off as too negative, I only would like to see more truly constructive info being offered up to the Alt-Coin mining community,

1-13 gpu's shouldn't be a problem.
But when this card got released people thought u could use 19 gpu.
In my country we cant order "mining gpu" like p104 or p106. So then we are stuck with "only" 13 gpu.

I got a few b250 on the way together with a bunch of gpus. I am hoping that Asus, windows and amd/nvidia will release updates etc so we can use 19 gpu in the future.
13 is better than nothing
