Topic: ASUS B250 Mining Expert & 12 gtx1070 problem (Read 643 times)

Hello

Anyone else here that have tried with 8 RTX cards? When adding the 8 card, I will not run the fans on that card

(yes, I know it is very odd)

I got 14 1070s working on b250 in win10, but I suggest the MSI H310-F pro motherboard instead or the other MSI H310 board that has 20 slots, if you want to run 14 cards. better board, better bios, newer chipset.

Thank you for your response. I will build just like that. Installing the best and right driver, and of course setting the best virtual memory. It would be fun to watch the machine earning for you while you sleep.

13 nVidia GPU's are no problem. Never tested more because the board is cheap as hell...

DDU your old driver and install the newest one. Increase your virtual memory ALOT! If you still have problems, install the cards one by one and check the device manager after each installing if the card(s) show up without any error. If you want, you can also start a quick mining session with all cards installed after.

Is this going to be a virtual memory issue?

no issues here with Windows and 12/13 AMD GPUs. works fine

Can we do it with Windows 10? or we need to do with Linux?

yes

I'm planning to buy ASUS B250 Mining Expert because it's cheaper nowadays.

But I have a question: Can we run 12 or 13 the same AMD GPUs with this motherboard?

I currently run Asus b250, i7-7700k nzxt water aio, 4gb ram, high speed samsung ssd, 2x pny xlr8 1070 8gb 2fan, Windows 10 build 1803, 2x1600watt psu Atacoin, msi af, multipoolminer.

One thing not mentioned much is to modify gpedit.msc and disable all defender real time protection. This will help with your miners being blocked by windows as it will auto reactivate constantly. Took me along time to figure this out. Also running that many gpus will require big page file in advanced settings. I set mine to 60000mb~80000. Having the fastest ssd money can buy, which is currently Samsung, will help with minimizing system lag. Mine will lag slightly through AF, but system is stable and very usable while mining full speed on gpu and cpu even with only 4gb cheap Amazon ram.

running 12 1080ti on h110 pro btc for one of my rigs. no bios mods, nothing. plug and play. SMOS. get on the gravy train, why make life difficult?

I just bought this board and surprisingly got it to work the first time, but I have read many posts and watched many youtube vids and have experience on other difficult boards. I currently have 12 Titan Xp's running on the B250. Here's the key things to make sure are in order to get this to work with NVidia cards you first time (or second), follow this advice to a tee:

1. Download the latest Windows 10 ISO from Microsoft and install a fresh copy.
2. Plug the cards in sequential order and don't skip slots. Only use 4GB ram modules.
3. Do not use any of the molex connectors on the board and only plug the first power supply 24pin into the mb, "A".
4. Make sure you have the latest BIOS and reset it to defaults. There is nothing that needs to be changed if the latest revision.
5. Load windows with the network cable unplugged. Don't update during install, and once Windows is loaded, disable windows updates.
6. With the network cable unplugged, install the latest NVidia drivers from a USB stick. Be patient. Deselect every option on the install, only install the drivers.
7. Reboot. Install Latest MSI Afterburner (Yes it will detect all cards). Reconnect to Internet.
Done.

Finalize: I advise to keep updates disabled and don't exceed 12 or 13 NVidia GPUs, though 106's or AMD can be added. Be sure to turn off sleep/hibernation.

My Setup:  B250, TITAN Xp (x12), i3 7100, two 4GB modules.

It is important to keep Windows off the Internet and disable the Windows update service. During your card setup, if Windows sees the Internet and can update, it will try to pull generic drivers for the GPUs and that's where everything goes wrong.  I played with the BIOS as soon as I fired up and this caused problems in my first 5 minutes. After resetting back to defaults everything fired up, Windows installed, and the driver install was flawless, so keep the BIOS at default values and resist the urge to play with it.

Another very important thing to remember is how to properly connect your PSU's. Use a proper PSU syncing module, the ones that use a SATA or Molex from the master and connect to the 24pin on the slave PSU, $5 on ebay. Do not use the B and C 24 pin connectors on the motherboard, or the molex connectors. And never ever share or cross PSU's to the same GPU. You must use the same PSU to power both the PCIE riser and the GPU 12v. Some people, and even some manufacturers don't understand how a switching PSU works. The bottom line is they can't share rails between each other, the delta during the switching phase can and will eventually burn out the PSU or GPU, or MB. And don't buy those PSU linking hubs from newegg, same problem. I don't know if the B and C channels are properly isolated on the B250 MB, but I do know it's safer not to use them. Your powered risers take care of that so just use the 24pin "A" and CPU power from your host PSU and nothing else.

Another observation I made is that the CPU is taxed quite a bit with this many lanes running. I think some of you out there may be bottlenecked if using a Celeron or other ultra low end CPU. With an i3, all four threads are moving at 25%-50% during mining on this rig using cudaminer, when normally it's less than 10% with 7 cards. Some have complained that the board becomes very slow when exceeding 8 cards. Installing and loading up windows was not slow for me with a 7th gen i3. Finally, use an SSD, it will save you valuable time during reboots and loading.

I hope these tips help save some headaches, time and cash.
Keep Mining.

Yes I plugged all molex to slots.

Windiows 10

you run it in which OS windows 7 ? 10 ? linux ?

Did you plug in molexs on motherboard slots ? Code 43 often means not enough resources for the device. If you plug in all of them then the motherboard itself might not go over 8 Nvidia cards . You should wait for bios update from asus

I didn't see such option in bios, can u tell me how to do ?

BIOS settings in the motherboard were checked for restrictions on the operation of video adapters?

If you're running Windows, that's 1 of your problems. I've always read that the cap for Nvidia GPUs was 8 for Windows 10. I'm using only ASUS B250 Mining Expert and run 8 GPU per build, have 11 builds so far. Prefer stability and zero issues. If you want more than 8, you're going to need to mix in AMD for GPUs 9 to 12, but I suggest sticking to 8, which you already know will run without issues.

   
Mobo  B250 Mining Expert
Cpu Pentium G446
Ram 8gb
Ssd 120gb
Psu  2x Xigmatek 1200w
Gpu 12x gtx1070
Sata powered risers

I can't make it work. I can see all cards in device manager but sometimes 6 cards with a error 43 and sometimes even 11 of them error 43.  All cards tried separately and all ok. I add another 1600w psu now running wit 3 psu but problem still same.

 try to install Nvidia dirvers but after checking system compatibility its  just crashes but when I try with 8 cards its updating without problem
