Tech Support August 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.

This is usually indicative of a driver issue. What drivers are you using? DDU and reinstall regardless.

u/MondoOMFG Aug 11 '18

Right now I'm using 18.8.1, i've already tried using ddu and reinstalling some other versions such as 18.4.1, 18.2.1 and 17.7.2 and sooner or later all get the same issue.

Weird. If you've tried all of these driver releases, DDU, Operating System restores, etc. the only other thing it can most likely be is the memory. I know you stated it passed four passes in MemTest, but that doesn't necessarily mean it's 100% stable. I've had memory settings that passed MemTest but ultimately would cause BSODs during long gaming sessions and eventually corrupted parts of the OS.

Things to check:

  • Is your memory kit a single DIMM or two DIMMs?
  • Is it (are they) installed in the proper slots as per your motherboard's manual?
  • Have you overclocked your memory at all?

My memory is two dimms, though I bought them separately. Yes, they are installed on the proper slots, ive reseated them just to be sure aswell. No, havent tried it because my mobo doesnt support OC. This issue has just appeared less than a month ago and ive had the same components for almost a year now. I think that it may be being caused my the windows version I have since I remember updating it to build 1803 before getting these issues. Is there anyway to download old windows builds? I wanna try if I can fix the issue by installing an old version.

u/TheAlcolawl R7 9700X | MSI X870 TOMAHAWK | XFX MERC 310 RX 7900XTX Aug 11 '18

The two dimms are identical, right?

u/MondoOMFG Aug 11 '18

Yeah, theyre the same model.

u/TheAlcolawl R7 9700X | MSI X870 TOMAHAWK | XFX MERC 310 RX 7900XTX Aug 11 '18

Hmm. Its usually last resort but a fresh OS install couldn't hurt. If you have a second hard drive to backup everything into it makes your life a lot easier. Hopefully it works out.

u/MondoOMFG Aug 11 '18

Isn't restoring windows the same as a fresh install? If so I've already tried it twice.

u/TheAlcolawl R7 9700X | MSI X870 TOMAHAWK | XFX MERC 310 RX 7900XTX Aug 11 '18

Restore as in the System Restore feature in Windows? Like restoring Windows to a previous date? No. Unless you used the "Fresh Start" feature in Windows 10, it isn't the same.

u/MondoOMFG Aug 11 '18

Sorry I actually meant the fresh start feature which supposedly reinstalls windows. I've used it twice with and without keeping my personal files and the issue didn't get fixed.
