Update: Problem solved ! ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)
Here is what you should;
Go to BIOS and update the bios to 1.D version
then go to Settings>Advanced>PCI subsystem Setting
Above 4G Decoding set to Enabled
(thanks to Tummler for settings)And very important thing:
U should use Skylake CPUs
If you use Kabylake u can mine only with 4 GPUs
I was in trouble because of that.
-----------------------------------------------------------------
I've MSI Z170A Gaming M5 Mobo -
https://www.msi.com/Motherboard/Z170A-GAMING-M5.htmlIt has 7 Pci-e slots but when i try to connect more than 4 gpus, i can't boot it.
First, I tried the latest BIOS driver - 1.DNothing changed
Then I tried these settings:- Bios Version 1.C;
- Into BIOS
Settings>Advanced>PCI subsystem Setting
PEG 0 and PEG 1 set to Gen2
Above 4G Decoding set to Enabled
- Settings>Windows OS Configuration
Windows 8.1 / 10 = "Disabled"
Windows 7 = "Disabled"
MSI Fast Boot = "Disabled"
Fast Boot = "Disabled"
Nothing changed
Then I tried PEG0 and PEG1 set to Gen1
Nothing changed
Then tried several combinations of these settings but Nothing changed.
I can't boot more than 4 GPUs but i know its possible.
Can anyone help please? Maybe I need Custom BIOS like "Z170A Gaming Pro Carbon"?
Thank you
