Topic: ASUS B250 Mining Expert MB - 19 Cards! - page 4. (Read 31101 times)

They are placed in a pillow box and standing outside
Fans blowing in and fans on rear blowing out.
Outside temp are 31C and gpus are 60C.

Look at youtube, a guy have done something the same. Outdoor mining rig in plastic pillows box.

Do you have any vents behind the cards or just natural airflow? Some new rigs have pre-made holes to mount 120mm vents behind.
If i remember correctly you have made your own rig from wood? Maybe you could just add one more plank with 2 L stands to mount few vents just to make some additional airflow.

I read some saying 85C some hours every week aint that bad.
Normally they are 70C. But these days are damn hot with 31C outside. The rigs are outside.

I hope drivers will update soon in order to work 19 amd GPU's or nvidia.

Why not set temp limit to 75 just to prevent cards from going all up to 85?
Throttling will decrease hashrate but that's probably better if you want longevity for the cards.

The 8100 will never work with this motherboard. The 8th generation processors from Intel require a 300-series motherboard to operate (e.g B360, Z370) because of 'power delivery issues' as stated by Intel. Even though the i3s shouldn't be an issue in that case, they still put in microcode locks on the cpu, etc. to prevent them from working in older boards. There have been somewhat successful attempts to put 8th gen chips in 200 and 100-series motherboards, but they were never very successful and only for some specific boards; anything that is 6th or 7th gen from Intel should work on this board. It's really not worth the effort to get 8th gen chips to work anyhow with possible compatibility and stability issues with multiple GPUs ahead if such a task were to be attempted.

Tarhet temp is 50C. Thwy arw normally around 65C. But during the 2 hottest hours they may peak to 85C. And 40C at night.

That CPU i3-8100 is currently not on the list of supported CPUs so for now don't count on that.
Maybe after next BIOS update will appear on that list.

can I use i3-8100 1151 on this board ?

you really should consider setting the temp limit to a lower temperature. 85C default limit is too high, you shouldn't run your GPUs with temperatures like that. 75-77C is much better.

My mistake. I ment 85C.
When they get to 85C they trottle. But this have only happened 5 times this year.

90C on the gpu?

I exchanged it for TB 250 12 cards one and that one is fine till now.

Strange... been running 4 of these nonstop since january. No problems. Temperatures from 25C - 90C (winter vs hottest days in summer).

this motherboard failed on me as well. I was lucky to return within a few days

Of course one of the 'cards' is the Intel built in one... I did see some opencl drivers for that recently  However has anybody made progress on a patch for this thing?  I did see references to the fact that you can hot plug during the POST to get past the card-lock.  

Has anybody tried either messing with the version strings in the firmware of you're cards to fake a P106? One or the other might be able to get it done... a bit frustrating that nvidia was returned a mad huge shipment from one of their Taiwan "big 3" wholesale partners due to low demand, hey ASUS lift this restriction and more cards will be moving off the shelf!!

With all the churn with the amd-gpu-pro driver opening up in https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-18.20-606296.tar.xz recently rebuilding to see how much difference that makes.

The combined AMD/NVIDIA MINING worked for me up too ethminer version 0.14.0.dev3+git.83693003 with;
ethminer -X -S X:8011 -SP 1 -O 0x1234 --farm-recheck 200 --opencl-platform 0

rebuilding to see if the current git version works...

Im running a 10002 and 850w PSU using pcie to 6 pin on the risers. (Only 2 cards are on each sata power cable).  8gb ram, 120gb ssd.  Windows 10 pro latest update and latest update for Bios from Asus. 
Mine just goes crazy in device manager when I add another card. I can only get 11 cards on rig 1 running somewhat stable.  When I add a 12th card (AMD 580) I get exclamation marks, hangups then eventually a BSOD.

Strange. Have u installed newest bios?
I have 2 evga g2 1600 psu on each rig and all risers are powered with 6pin pci-e. 4gb ram, ssd etc.
All rigs are stable.

My rig 1 (AMD) RX 580,570,560 isnt near as stable and ive got (4) 580 (1) 570 (3) 560 and it absolutely refuses to let me add another Amd card before throwing up all over itself.  So I have 3 nvidia  (2) 1050 TI (1) 1060 on it also.
Whats your trick for all AMD?

Yes. 13 nvidia or 13 amd.

I have 13 amd 570. Rig drawing total 1550w
