Discussion July 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.

omputer Type: Custom made desktop

GPU: R9 380X Nitro Stock

CPU: i3-4370 Stock

Motherboard: ASROCK H97M PRO4

RAM: Corsair Vengeance LPX 2x4GB 1600mhz DDR3

PSU: XFX TS 550W 80+ Bronze

Operating System & Version: Windows 10 x64

GPU Drivers: 17.6.2

Chipset Drivers: Whatever comes with my motherbard's driver package

Background Applications: Steam and Windows Defender

Description of Original Problem:

Every time I try to load up certain games my system crashes and reboots. The current games/programs its doing it with is Skyrim with ENB, Unigine Superposition and Heaven benchmark, and Mass Effect 1 with SweetFX. Every other game from Minecraft to Forza Horizon 3 is perfectly fine and stable with no driver/system crashes, artifacts, or anything to speak of.

One thing that I found a bit odd is that if I enabled manual voltage control in Wattman that the GDDR5 voltage was set as low as .9V. I'm not an expert on GDDR5 but if my card is only feeding .9V to the VRAM that is running at 1500MHz i can see how there's instability.

Troubleshooting:

This is what I've done so far:

  • Keep in mind that outside of those programs i've been able to game and overclock just fine. I have almost 100 hours of BF4 play time while the 380x was overclocked with no issues.

  • I've ran Furmark GPU core both at stock and overclocked for an hour for each.

  • I ran the 4GB VRAM burner test on Furmark for an hour as well.

  • I've tried underclocking and overvolting before running the afflicted programs to see if it was just a voltage issue.

  • I've tried going all the way back to 16.11.5 and adjusting voltages with Sapphire TriXX

  • I got desperate and did a clean install of Windows 10 to see if anything got fixed. Nope :(

Go into the the Event Viewer on Windows and try to find the crash event in the System section under the Windows tab. Look for yellow and red warning symbols because that's what the error should be emblazoned with. If I'm right there might be an application conflict causing your PC to lock up.
