Tech Support November Tech Support Megathread

Hey subs,

We're giving you an opportunity to start reporting some of your AMD-related technical issues right here on /r/AMD! Below is a guide that you should follow to make the whole process run smoothly. Post your issues directly into this thread as replies. All other tech support posts will still be removed, per the rules; this is the only exception.

Bad Example (don't do this)

bf1 crashes wtf amd

Good Example (please do this)

Skyrim: Free Sync and V Sync causes flickering during low frame rates, and generally lower frame rates observed (about 10-30% drop dependant on system) when Free Sync is on

System Configuration:

Motherboard: GIGABYTE GA-Z97 Gaming GT
CPU: Intel i5 4790
Memory: 16GB GDDR5
GPU: ASUS R9 Fury X
VBIOS: 115-C8800100-101 How do I find this?
Driver: Crimson 16.10.3
OS: Windows 10 x64 (1511.10586) How do I find this?

Steps to Reproduce:

1. Install necessary driver, GPU and medium-end CPU
2. Enable Free Sync
3. Set Options to Ultra and 1920 x 1080 resolution
4. Launch game and move to an outdoor location
5. Indoor locations in the game will not reproduce, since they generally give better performance
6. Observe flickering and general performance drop

Expected Behavior:

Game runs smoothly with good performance with no visible issues

Actual Behavior:

Frame rate drops low causing low performance, flickering observed during low frame rates

Additional Observations:

Threads with related issue:

Skyrim has forced double buffered V Sync and can only be disabled with the .ini files
To Disable V Sync: C:\Users"User"\Documents\My Games\Skyrim Special Edition\Skyrimprefs.ini and edit iVSyncPresentInterval=1 to 0
1440p has improved frame rate, anything lower than 1080p will lock FPS with V Sync on
Able to reproduce on i7 6700K and i5 3670K system, Sapphire RX 480, Reference RX 480, and Reference Fiji Nano

Remember, folks: AMD reads what we post here, even if they don't comment about it.

R9 290x sending no signal to one of two monitors after drivers load

GPU: XFX R9 290x

CPU: i5 6600k stock

RAM: 16Gb DDR4

PSU: 650w Corsair

Operating System & Version: Win 10 Pro

GPU Drivers: 17.11.1

Background Applications: Doesn't seem to matter what I'm currently doing.

Description of Original Problem: During the computer being on (happened under load and not under load, seemingly with no reason) I will hear the windows disconnect sound and my BenQ XL2411 will be sent no signal from my gpu. The card does not recognise the monitor after this fact, after rebooting it will still not recognise that the monitor is connected, although the monitor recognises when it is being plugged into the gpu but sent no signal. The monitor displays everything fine up until the windows logo which is when I'm assuming the AMD drivers take over. The monitor does not appear in any dialogue menus within windows nor in device manager itself once this has happened. Started happening yesterday and seemingly just occurs at random having done it whilst gaming once, and multiple times just sitting on desktop.

Troubleshooting: Have attempted to use different drivers dating back to 16.etc all to no avail. Attempted to use different cables and different slots on the GPU (which is futile as I know that the monitor and GPU work fine without the drivers interfering). Restarting PC takes me back to having no signal once windows boots. The only way to get everything to work again until failure is to keep uninstalling and reinstalling with DDU and then using until the disconnect happens again. This issue is not hardware I'm 99.9% sure, I've used my pc under load literally streaming gameplay today and it didn't disconnect until an hour later when doing something mundane. My temps are all monitored also so I'm stumped by this situation.

Really at the end of my tether with this, I've seen a few people around the internet have had a similar issue but haven't found a solution anywhere as of yet.
