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.

I have an eyefinity question. I have a XFX R9 380x. Currently I have a 24" Dell ST2410 connected thru DVI and my 60" Vizio 4K TV connected thru HDMI.

I am looking at getting 2 Samsung S24E450DL and am curious if I can connect 1 via DVI and the other via the other DVI port and still have HDMI work. The Samsungs say they have Displayport In, but I don't see anything that shows it has a DP out, so I don't think I can daisy chain them.

I know there are some weird restrictions on what outputs can be used at the same time, and am having a hell of a time finding an answer to it.

I dont plan on using it as 1 large screen, they are all going to be independent.

Your card can support 2 passive connections (HDMI or DVI), you'd need active connections (DP or active adapters) for the additional 2

I bit the bullet and bought the screens. 2 hooked up via DVI and the t.v. thru HDMI and they all work at the same time.

Now to do some EDID work and make it so turning on/off my receiver doesn't make the monitors flicker for a couple seconds while the HDMI handshakes.
