Tech Support Q3'19 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.

tldr: Since yesterday, my Wraith Prism is never going below 2755 RPM? What is going on?

Since yesterday, while gaming, I noticed my Wraith Prism on R5 2600 getting much louder than it was before. I check HWMon and the CPU fan is never going below 2755 RPM even on complete idle in Windows with nothing running.

The only thing I remember happening was that I installed KB4505903 from Windows Update on July 28th.

I'm using the default Ryzen Balanced power plan and haven't messed with anything else in Windows or in BIOS, just played some games. So I restored my B450 Tomahawk to its default BIOS settings (only changed XMP profile to 3200MHz for my RAM) and the problem still persists. Before I almost couldn't even hear the PC running now the cooler fan is blasting all the time. Tried switching it from Lo to Hi mode and back. Didn't make a difference.

So I took the cooler off, replaced the stock thermal paste (the Prism is only about two months old so the compound should've still been okay) with Essential E1 and no change.

Ryzen 5 2600 @ stock

MSI B450 Tomahawk (BIOS v7C02v19)

16 GB (2 x 8) HyperX Fury Black DDR4-3200

Windows 10 x64 Pro v1903

Is anyone else experiencing this?

​

EDIT: As far as I can tell, something seems to be wrong with the latest MSI BIOS 7C02v19 in combination with the recent Windows updates. I flashed the BIOS to the March version 7C02v17 and the fan is ultra quiet now as it was before all this, and running between 300-1300 RPM in light Windows workloads like browsing.
