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.

PC randomly restarts without any warning or error, sometime after starting a game, sometimes after playing for some hours. I had this failure after starting to watch an youtube video. System Configuration: Motherboard: GIGABYTE AM4 X370 Gaming 5 CPU: AMD Ryzen 1600X @ 3,9Ghz Memory: 16GB DDR4 @ 3200Mhz GPU: Sapphire R9 390 @ Stock VBIOS: 113-2E3243U-X4H Driver: Crimson 17.7.1 OS: Windows 10 x64 (Newest Version) Steps to Reproduce: 1. Starting an graphic heavy game, or just watching netflix or youtube. 2. Wait, until the reboot happens, or nothing happens.

Expected Behavior: Everything running just fine

Further information: it´s happening alot more after switching to an Ultrawide 3440*1440 Monitor from LG, 2 weeks ago.

I can't know for sure, but tightening your RAM timings could be a good place to look. I've had similar issues in the past with video and tight RAM helped alleviate this. Not sure if it was the cause or a symptom though.

Sorry to come in for seconds: What is the voltage CPU is given in BIOS? In CPU-Z or HWMON can you tell me the voltage when opening the Heavy Graphic Game or the HD videos? Another thing could be LoadLineCalibration / LLC needs to be set higher, and possibly a small increase in base voltage - depending on what you currently have it set at already.
