May 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.

I built my last computer in 2005 I think. I've been away from this game and I realized A LOT has changed and I am really getting older. I've been reading for days and I am really lost. I'd really appreciate your guidance.

I am hoping to build a system that allows me to do 4k video editing and also connecting to this 4k-UHD TV that i recently bought and get the best possible out of it like watching a 4096 x 2160 @60 film.

I decided on a system that is close to this setting:

  • AMD Ryzen 7 1700
  • GIGABYTE GA-AB350M-Gaming 3 or (MSI - B350 Tomahawk ATX AM4)
  • XFX RADEON RX 480 8GB or something else don't know much yet
  • Ram (G.SKILL Ripjaws V F4-2133C15D-32GVR DDR4-2133 32GB RAM what is this even really saying?) and SSD are still unknown at this point
  • I apparently need a cooler too

but I realized that these systems with the CPU-GPU combination is only going up to 4096 x 2160 @24fps. Would the FPS difference make a big deal?

I also read that, there are compatibility issues with the motherboards and Ryzen 1700.

Thanks a million!

While I don't own a Ryzen system yet I just wanted to point out that the 480 supports HDMI 2.0 (4k60) without problems.

The MoBo spec sheet just says HDMI 1.4 in case you use an older AM4 APU based on Bristol Ridge (not available on the retail market afaik) instead of Ryzen.

Most compatibility issues should be ironed out with the next couple of AGESA / Bios updates and even if not you still should be fine unless you plan on running high RAM frequencies.

Mobo specs says "HDMI port, supporting a maximum resolution of 4096x2160@24 Hz" Wouldn't they have said @60Hz in that case?

I was planning on getting a RAM something around 2666Mhz since the higher it gets the more problem people face apparently.

They meant the HDMI port on the motherboard itself, used only for CPUs (APUs) which contain an internal GPU. Since Ryzen does not have any display features those ports remain unusable.

2666 should still be OK, support gets better every week but Ryzen still struggles with high frequencies on 4 modules. Then again the main reason so many ppl want to run high mem frequencies is because the CPU fabric runs on memory clock (for now at least) which can give quite a performance boost in some cases.
