Topic: Sapphire RX Vega56 mining rig reboots after installing drivers on Windows 7/10 (Read 236 times)

Hello!
I have a similar problem.
Win 7 + PCI-E 2.0 + RX Vega56 + Blockchain Driver 17.30.1029.

Everything works fine on any other ATI driver. Has anyone found a solution?

Thanks for the replies, I will try another mobo today, to see if its the problem of PCI-e 2.0

If that is the case no other option left rather then going for a Linux distro or Simple Mining OS, or ethOS. There are a lot of other options to try. Sorry to hear that Windows 10 is giving a lot of blue screens, I thought this was only a Nvidia problem and not a ATI one.

Yes, I did try Windows 10 as I mentioned before, but I got a lot of bluescreens, even when installing recommended drivers for Vega56, I did not get these errors on Windows 7 until I tried to install blockchain drivers.

I wonder why you are on Windows 7 when Windows 10 Pro is the best OS from Microsoft side for mining, especially with latest updates that supports unlimited number of GPU-s while Windows 7 doesn't. Before jumping to Simple Mining OS, try Windows 10 ,install all recommended updates then start by testing cards 1 by one until you reach the point where you can mine in a stable way.

Thanks, I will try using Simplemining OS today.
Any other suggestions what might be wrong ?

I'll recommend you to give Linux Distros a try like Simplemining OS, nvOC for AMD, ethOS, PimpOS.
They are already built with all the miners inside.

Hello,
I am building my first GPU mining rig (GPU - (6x) Sapphire RX Vega56; Motherboard - H81 Pro BTC 2.0; PSU - (2x) EVGA 850W; SSD - Corsair force 3 60GB; RAM - Kingston 4GB 1866MHz DDR3 CL10 DIMM HyperX Fury Red Series) and there are a couple of issues regarding GPU drivers:
1) When Official recommended drivers (from AMD Radeon Official Driver Utility) are installed on Windows10 there are a lot of BSOD (Kernel-power 41 and other) while trying to install other drivers or opening AMD Radeon Control Panel. We didn't try to install Blockchain drivers on Windows 10, but I have a feeling that BSOD's wouldn't go away.
2) While using Windows 7 and the newest official drivers - everything works fine. However, after uninstalling these drivers with DDU and installing blockchain drivers (also tried installing them on top of recommended drivers) - PC instantly reboots and shows an unexpected shut down table (BSOD error) when HDMI is inserted to GPU from Motherboard (while PC running). And if the rig is being turned on with HDMI inserted to GPU then it keeps rebooting without showing anything on the monitor.
Some details: - There is only 1 GPU connected to the motherboard and it's inserted into main slot; - Motherboard has PCI-E 2.0 while PCI-E 3.0 is required. However, I've read articles that people are running rigs with identical components to mine (read above).
In Overall, the rig is able to mine, but it would be great to get some help regarding these issues.
P.S. Yes I've tried different GPU's and different risers, as well as PCI-E 16slot.
P.P.S. There are many people using PCI-E 3.0 card in a PCI-E 2.0 slot, because as far as I know they are backward compatible, is that right?

Maybe simplemining OS could help?
