FYI, I have have sapphire rx480 nitro+ 4gb and setting gen1 and above 4g locks my computer up. I had to set them back to defaults, I have not tested 7 cards yet. This is the msi z170a pro gaming carbon with 8 gb of 2300 ram and a g4400 pentium proc
Would it be possible for someone to share a setup that got more than 4 cards working on the msi z170a gaming pro carbon, no matter what I try, linux crashes at boot with 5. All the tricks in the walk through did not work

Hi first thanks for that information but you think that i can put 7 R9 Fury? Don't waste your breath with this, numerous others on this forum have tried and wasted money on a 150$ motherboard that only holds 4 cards. This thread was probably created to boost sales or something, who knows. |

I have a MSI Z170A mobo.
I have gotten 6 cards to be detected. But 6th card does not behave properly. Fans run at 100% and it mines very low hashrate. Now 6th card is only detected if it is plugged into 16x PCI slot E_2 (silver colored) SLI slot. If it is plugged into E_5 the other silver SLI x16 slot, it is not detected. Even when I put 7th card, 7th card is not detected in E_5 and GPU in E_2 still runs fans at 100% and very low hash rate.
Anyone know what is going on and how to fix?

I want to buy new version MSI Z270 Gaming Pro Carbon or Asus Prime Z270-A.
Do you think that it will be working with all PCIE slots (6/7 GPUs)?
I've got asus z270-a. 7 gpu works fine What BIOS settings? How much RAM in your GPUs? I have same MB and can only run 4 GPUs |

Don't waste your breath with this, numerous others on this forum have tried and wasted money on a 150$ motherboard that only holds 4 cards. This thread was probably created to boost sales or something, who knows. I confirm these settings to be working on a Z170A pro carbon. Thanks @mining-hardware ! @bughatti : It's strange it doesn't work out for you. My setup is the follwing : 7 RX480 Nitro 4GB, G4400 CPU, 4GB Ram (cheapest i could find), 1600W PSU, win10. |

Just to clear things up: "above 4G" means 64bit addresses for all devices, including HD so your drive should be GPT and boot should be UEFI

pc ram - 4gb
7 x rx480 8gb
I dont know what exactly helped to run 7 gpu, but here what I changed:
above 4g decoding - enabled
pcie switch to gen 1
dmi max link speed switch to gen1
disable all sata, which is not used
disable all usb, with is not used
Ok, I have replicated Andrews experience. Here's what I found: -- Had to flash the BIOS. Board shipped with 5.0.0 and I updated it to the latest (7.0.0 I think)-- this is necessary to get the "Above 4g decoding" option. Which appears on the boot menu in the bios. -- PCIe switched to Gen2 -- Didn't make the other changes. WARNING WARNING WARNING When I flashed the BIOS the onboard network hardware stopped working with linux. this caused a bunch of problems. I had to run this utility to refresh the network drivers ROM to make things work: https://downloadcenter.intel.com/download/19186Current setup for this board- -- Ubuntu 16.04 server -- 7x NVIDIA 1070 8GB Cards Working fine. (And about %10 more hash under linux than under Windows.) |

Thanks! Hi mate, your windows 10 installation should be in uefi or it should support uefi in bios not legacy, windows hardrive should be in gpt format otherwise the above 4g setting won’t work and you will get a black screen when you try to boot into windows 10. - Windows 10 - PCIe GEN1 - Above 4g decoding enabled - BIOS Version 1.H Please notify me if it work. |

Hello team, I am really hoping someone can help here. I am on my second MSI z170A carbon and I can not get a boot screen to show up. I have followed the guide and not installed any gpu's and am using the onboard HDMI and tried the onboard dvi. Tried 2 different monitors, also 2 sets of ram and 2 different procs. When I watch both of them boot i see the diagnostic lights flash for ram and cpu but never for vga. I have reset the cmos. Am I missing something here?
Proc: Intel BX80677G3930 7th Gen Celeron Desktop Processors
Mem: Kingston HyperX FURY Black 8GB Kit (2x4GB) 2133MHz DDR4 Non-ECC CL14 DIMM Desktop Memory (HX421C14FBK2/8)
Tried memory with just 1 stick in slot 2
Your problem seems clear. As far as I know, 7th gen is kaby lake cpu and the z170a mobos are not compatible. You either need a skylake (older) cpu or a z270a mobo to support a kaby lake cpu. |

Actually they are compatible with kaby lake once you update the BIOS to the last version. However to do this, you need ... a skylake CPU :p |

There is a way to get 5 cards running without the above 4g encoding option and skylake cpu.
-set pcie gen 1
-Enable the internal graphics, but use the pci for the screen. (dual display)
-boot. (if you get a freeze, you need to reinstall windows from scratch.)
install the driver for the 5 cards. then disable the internal graphics. Reeboot, and you have 5 working cards.

No, 8 cards do not work on Windows, only work on Linux. And I can not under-volt on linux, so my 1000W PSU can not handle 8 cards. |
