here what I have done, and yes sometime with AMD a little thing can screw up everything

1. installed my 2 gpu
2. installed windows
3. installed amd driver
4. on the next reboot disable StartCN or each time you boot, you have to kill the AMD software CTRL-ALT-DEL and kill the red Radeon icon
5. install amd tweak
6. install afterburner reboot
7. first thing i do in windows is:
   7.1 run and apply tweak
   7.2 run afterburner to set the fan and apply only once
   7.3 start miner

other step that could be perform is to install windows update and windows tweak to previous reboots sleeps... etc.

Also, as mention below, a bunch and I say it agian a bunch of driver didn't work for me.

hope that will help

Hi,

I thought that maybe I could share my settings and asked a question in the same time. This computer is used only for storage and I run 2 Vega 56 with 64 BIOS in it to mine and I am getting 50.77Mh and 50.67 Super stable.

Question 1: I do not have the option in AMD Memory tweak to set the Fan speed.
Question 2: My Vega Memory goes to 73C. Is this high? when it will start throttling? or when it's bad?

My VEGAs 56 are running 64 BIOS

I have also had a lot of problem with AMD drivers and here are the one that worked for me:

17.11.4
17.12.2
18.1.1
18.2.2

MOBO:P5Q PRO
CPU: E8400
RAM: 4GB
STORAGE: Kingston SSD
GPU1: RX VEGA 56 GIGABYTE Air Cooled 1 fan turbine (SAMSUNG MEMORY)
GPU1: RX VEGA 56 GIGABYTE Air Cooled 1 fan turbine (SAMSUNG MEMORY)
PSU: EVGA 750w
Drivers: 18.2.2
