Topic: ASUS B250 Mining Expert MB - 19 Cards! - page 5. (Read 31101 times)

You can run (13) 1070's on the Mining Expert m/b.  If you have any problems just post here, PM me or create a new thread as to your symptoms.  You can run 6 P series cards too. Let me know where you find any that are cheap enough to buy!

Same brand?  What are you talking about?

My Rig 2 has all Nvidia cards and they arent all the same brand or type.  (7) 1050 TI (2) 1080 (4) 1060   Theres MSI, Zotac, EVGA, Gigabyte all in there.  Its been running rock stable for 4 months now.

120gb ssd
G3920/30
8Gb ram
Use onboard video
850w and 750w Psu
65% TDP +150 +500 on most of the cards.
Draws 10-11 amps.

Huh? They never promised that we could run 19 regular gpu.
The bios update enabled use of 13 gpu of same type (nvidia or amd)
13 gpu + 6 mining gpu

I have been running 12 x 1070 for 7 months now, was just waiting for the promised bios update that never came.  I am looking to add more nvidia cards now, to my understand, the max / best I can add is 1 more gpu and 6 mining cards?  Like running 13 x 1070 and 6 x P104/ P106 ?  Would that work?  Thanks!

anybody run 11 amd + 8 1060/1070 or 1080?

If you had problem with your memory, fan would spin up at least.
IF you didn't plug additional CPU power fan would spin and stop.

You said already that you have another PSU so no problem there.

Either your MBO is DOA or you are not using correct PINS for POWER button.

Check it once again just to be sure

Is the CPU fan spinning up?  Have the 8 pin CPU power cable plugged into the board? Have the start switch connected in the right place?

Just bought this board and.. its not starting when I press start button nothing happens.
Please guys tell me I didnt buy wrong cpu or memory.

It has:
Intel G4560
Kingston HyperX FURY DDR4 2400 MHz CL15 4 Gb
Power supply is Super Flower 1000w platinium and it is connected place A.

Edit:
Tried different power supply and ram slot's nothing changed. No power at all, no lights.

I hope AMD release their driver that will enable this mobo to handle 19 same cards like AMD cards, is this posible? or the problem is on the mobo's chips adn platform? Has anyone tried to insert morethan 13 same cards?

Wondering if anyone can advise with a bizarre setup problem I have with this board.

I've modified the BIOS settings (latest bios updated) as recommended on various posts (but perhaps I'm missing something?).
Above 4g on, PCI-E speed (tried Auto, Gen1, Gen2), onboard sound is off, turned off all SATA ports except one driving the boot SSD.
No board molex used.
All gpus and motherboard powered directly from an EVGA 1600w Gold

I've seen a lot of people are driving their mining using Linux - so I've opted for Xubuntu (doesn't matter which linux flavour - I think ?) 18.04.


Problem:
4x 1080Ti plugged in ports 1-4 .   -> bios in CSM mode (Legacy boot) .   Board fails to post.
If I take out GPU from port 4 -> board posts, can boot into Xubuntu - all good.

I've swapped the GPU cards - (port 4 card into any of ports 1,2,3)  - and board posts  - OS boots -> so I believe the problem is not a faulty GPU card.


If I turn CSM off -> then the board posts with all 4 GPU cards -> but I'm in UEFI mode now - which means no 3rd party unsigned (nividia drivers) in Xubuntu.


Am I missing a trick here  - maybe some bios settings I've not tried ?  Or should I resign myself to keeping UEFI on and building this rig for Windows 10 ?

I'm on the latest BIOS firmward update (btw)  - dropping back to previous bios version is one option I've not tried yet.


Would appreciate any help/advice you guys might offer ?

The idea is to spread evenly.

I am using 6 pin for the risers with a 6-pin to dual 8(6+2)-pin. Haven't used SATA connectors for power as they don't meet requirements.

I have one last test... the first 6 GPUs use my first order of PCI-E risers... I ordered a second batch from the same manufacturer on Amazon, but they weren't identical (which was super weird!) things were soldered upside down, sloppy, and also some things weren't soldered aligned... I am now suspecting that this second batch of risers are all faulty. To test this I will attempt to use the G2 PSU with the first batch of risers.

The ASUS boot up screen shows 8 green slots, and anything above 8 shows red slots... be it 9, 10, 11, or 12 GPUs connected.

Your power hookups look ok and so does the spread of power across each power supply (8 pin).  Im curious as to what your configuration is for power to your risers? 6pin, sata?(At riser).  Are you using the traditional 6pin at the riser then have a cable that goes from the 6pin to SATA?  It is very important to maintain limits on the SATA power bus (On each SATA Cable) and connect the SATA power in the correct spot on the PSU. (I would not exceed to GPU Risers connected to each SATA cable but I have been successful connecting (3) 1050TI's to one SATA cable)  Be careful about accidentally connecting to the "8 pin" CPU connection on the PSU if it isnt used for what it is intended for (CPU connection on Motherboard).

Your ASUS PCIE torubleshooting screen (First to boot up before windows), does it show green for all slots used on the motherboard?

Well, I received an identical brand new replacement EVGA G2 1000w PSU within less than 24 hours... gotta love Amazon's customer service!

I am still encountering the issue. I removed all of the old cables, and used all of the new ones from the new PSU.

Attempt 1:

PSU 1 (EVGA GQ 1000w)
(4) 1070 ti @ 140w
Motherboard @ 200w <---- everything works


PSU 2 (NEW EVGA G2 1000w) changes:
(2) 1070 ti @ 140w
(1) 1060    @ 100w <----- 1060 wiggles and jiggles, have tried the other three and they do the same...

or

(2) 1070 ti @ 140w
(2) 1050    @  75w <---- everything works

I can for the life of me figure out what is going on... perhaps some kind of circuitry protection for the G2?

I have noticed something interesting that I may have originally missed.

In the VGA cable configuration, the manual states:

1.) VGA1-VGA4 should be 4 x PCI-E 8(6+2)-pin
2.) VGA5-VGA6 should be 2 x PCI-E 6-Pin + 8(6+2)-Pin

I connected cables to suggested connectors on the PSU. No Change.

My last attempt will be to swap the G2 as PSU 1 for the motherboard, cpu, ram, usb thumbrive and 4 1070 ti video cards to rule out PSU.

The only other thing is the BIOS, as it may be a finicky motherboard issue with the current 1010 BIOS and possibly downgrading the BIOS to version 1006.

Any other thoughts?

Thanks for the help and time

If somebody want i can post a drawing of frame from plywood for laser cutting. for 20 cards.

I had the same problem with rx580 so stopped using msi

now I use claymore to control fan, temp, OC and voltage with latest amd drivers

Excellent troubleshooting and detailed results along with test setup.  Your results all point to the PSU#2 being bad.  Internally we know (with your info provided) That all common points in the power conditioning of the PSU are good.  The output current capacity is doubled by paralleling rectifiers (this cheaper than installing just one high current output).  It sounds like you lost one of them or the controlling electronics but I believe those are common to both rectifiers.
To totally prove PUS#2 as bad just swap PSU 1 and 2 position and see if all the problems move to PSU#1 spot.  If the problems do move to there then PSU #2 (previous) is bad.

EVGA has 1000w PSU's for $119 and $149 (the price just went up, they were around $109.  I just got 2 in last week.  Great deal.  They are located in B-stock on their website.  Limit of 2 each type.  I have the feeling my mother is going to be receiving shipment of some power supplies for me in the next state over once I hit my limit. hahahaha

EVGA sold out of the one model.  But they still have the one for $119. Both of mine came with everything they do when bought new. https://www.evga.com/products/product.aspx?pn=210-GQ-1000-RX

Thank you for your input.

I decided to follow your input and break up the cards to different PSU's, but still have an issue:

ATTEMPT 1

PSU 1 (EVGA GQ 1000w):
(3) 1070 ti @ 140w
(2) 1060    @ 100w
Motherboard @ 200w <----- everything works

PSU 2 (EVGA G2 1000w)
(3) 1070 ti @ 140w <-------- 2 cards power up normally, but the 3rd has that fan wiggle/jiggle... swapped it out for a 1060... same issue...

ATTEMPT 2:

PSU 1 (EVGA GQ 1000w)
(4) 1070 ti @ 140w
Motherboard @ 200w <---- everything works

PSU 2 (EVGA G2 1000w)
(2) 1070 ti @ 140w
(2) 1060    @ 100w <------- both 1060's (previously worked in Attempt 1) fail to spin up fully and both have that wiggle/jiggle...


ATTEMPT 3:

PSU 1
(4) 1070 ti @ 140w
Motherboard @ 200w <---- everything works


PSU 2 (EVGA G2 1000w) changes:
(2) 1070 ti @ 140w
(2) 1050    @ 75w <----- everything works...


Could it be that the G2 PSU isn't supplying enough power and may be faulty?

I can't see why the second PSU, which is a newer model and also is gold rated at 1000w from EVGA is unable to power up three 1070 ti video cards, or even two 1070 ti and two 1060 cards.

I am stumped  

Thanks for your time and help.
 

there was no need for that when i set up this mb for a friend, igpu and afterburner worked no problems.

With afterburner, you have to directly connect at least one (1) AMD card to your monitor in order to access voltage settings. Of course, there are better ways to access voltage settings for AMD through other tools like OverdriveNtool which is a much ligther and in my opinion a better overclocking tool.

You should be able to find a lot of comments about overdriventool here on the forums. It's widely used.
