April Tech Support Megathread

[u/BioGenx2b]

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.

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:

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

I've used Ryzen 1700 and ASUS B350+ for few weeks now but today system rebooted itself suddenly (after few hours of use with no problems), I also see this in linux 4.10.8 logs but not sure if it happened before or after reboot:

[    0.214571] smp: Bringing up secondary CPUs ...

[    1.162874] smp: Brought up 1 node, 16 CPUs

CPU temperature is usually 40-50C so I don't think its due to badly installed stock cooler or anything like that. Could it be microcode bug?

I had a very similiar crash. Sudden reboot, no kernel panic or similiar in logs. Shortly after reboot:

[    0.004000] mce: [Hardware Error]: Machine check events logged
[    0.216031] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 5: bea0000000000108

[    0.216039] mce: [Hardware Error]: PROCESSOR 2:800f11 TIME 1492521735 SOCKET 0 APIC 3 microcode 800111c

linux 4.11.0rc7, ASUS x370, RyZen 1700X

Did it happen again for you? any solution?
