 Topic: Issue with 5th gpu on B150-X1Posted: 22 Jul 2016 at 1:17am |

Hi Can't get my 5th gpu working on this Asrock B150-X1 motherboard. Every time I install the 5th gpu it will give a code 12 error on 2 or 3 gpu's. I'm using 1500w Coolermaster and 500w EVGA psu's with add2psu to power the system. Using 3 R9390's and 2 R9290's. It's running on 4 gpu's at the moment on the Coolermaster psu. any advice will be appreciated. Thanks

I assume you mean a Device Manager Error code 12, which means: This device cannot find enough free resources that it can use. Power to the video cards is not the problem. What "free resources" is referring to means several things, such as memory, or the assignment of hardware resources. This is a description of hardware resource conflicts that cause a DM Error code 12: Two devices have been assigned the same input/output (I/O) ports, the same interrupt, or the same Direct Memory Access channel. The assignment was made by either the basic input/output system (BIOS), the operating system, or a combination of the two. Or it can be memory related, the amount of memory allocated to the OS is not enough for the additional video card. We'll hope it is the memory allocation to the OS for its own use, since that is easy to change and requires no research into DMA channels, IRQs, etc, needed to find resource conflicts. In your board's UEFI/BIOS, in the Chipset Configuration screen, find the Top of Lower usable DRAM option. Set it to Dynamic, and then Save and Exit the UEFI/BIOS. How much memory do you have in that PC? If it is 4GB or less, when four GPUs are running, you should run the Windows Resource Monitor, from Control Panel, Administrative Tools, and see how much memory is Available. If very little is available, changing that option may not help. If changing that option does not help, and you have plenty of free memory, clearing the BIOS with all five cards installed (and restoring any of your essential BIOS settings before the PC boots) might sort out any hardware resource conflicts that may exist. If all of the above does not help, you would then start looking for the resource problem by running msinfo32 from a command line prompt in Windows. |

You are populating all 5 of the PCIe slots on that board with exceedingly power hungry GPUs, even if you are able to resolve the IO conflicts and get them all working I wouldn't advise it. Each card is drawing 75w through the slot, this isn't an issue for the 2 full length slots but could cause issues with the x1 slots. The board (a mid range B150) is not designed to handle that kind of power draw through the PCIe x1 slots. It does not matter how powerful/how many PSUs you use it is going to seriously shorten the lifespan of the board. This is even more the case if the system is used for folding (which I would assume is the purpose of the system).
Please bare in mind, the above is just advice based on my experiences. How you use your system is up to you  If the system is going to be used exclusively for folding then I would start by going into the BIOS and disabling every port/feature that uses IO resources that you are not using. 4 GPUs are working and getting enough power but until you can resolve the IO conflict (if possible) you will not know if the 5th is pushing the system too hard. If you can get all 5 working that will be a beast of a folding machine. I wouldn't build based on the 390/290 because power is expensive here but if that isn't an issue for you then you will get some very solid numbers. Good luck.

Parsec and Xaltar I have 8Gig ram, looks like system's using only a quarter of that ram with 4 gpu's while mining. I'm waiting for a 1000w corsair psu for my second rig, running 5 9290's on a H97 Anniversary with 6 pcie slots. I'm using the 500w Evga to power the mobo and 5th card and a Huntkey 1200w to power the other 4 cards. I think it is IO conflict, but thinking maybe I must settle with 4 gpu's as 1 of my 9390's died, took it in for repairs, but that company told me to take the card back to gigabyte. If I can get the Anniversary to run 6 gpu's and the B150 on 4, it will take some time before I'll try 5 cards on that rig again. Please be patient, I will give you feedback if Gigabyte can repair the card or when I'll buy more cards. |

Just a quick update guys! Second rig running on 6 gpu's for almost a month now and gives me 185mhs mining only ethereum or ethereum classic. Still waiting for feedback on broken card.
