Sapphire Nitro + 5700 XT Recurring Issue

[Kenoxabe]

Title.

 

Issue at hand : GPU keeps getting error randomly and makes the 1920x1080 resolution unavailable in the display properties (monitor keeps getting set to 1680x1050 resolution at 60hz), 144hz option also not showing on the Display Adapter Properties.

 

Bought the gpu last November 15. Was doing fine for a couple of days. After turning my computer 3 days of initial purchase, I saw that a popup error occured from Radeon GPU Driver:

 "AMD Wattman has returned to its default settings"  

 

etc etc.

 

From then on, I've been experiencing the issue for about 5 times since date of purchase.

 

Steps that I did:

1. Re-seat the GPU.

2. Several PC Resets.

3. DDU even before installing the gpu out of the box. Issue appeared.

4. Unplugged DP Cable to use HDMI then switched back again to DP Cable. Worked for a couple of days. Issue re-appeared.

5. DDU again (safe mode). Installed GPU driver. Issue re-appeared.

6. Reformatted Windows 10 and updated to Build 1909. Worked for a couple of days (until last December 10). Issue re-appeared.

 

 

I'm now leaning to selling my GPU and buy a 2070S. Too tired and fed up already in troubleshooting this GPU. 

If anyone of you has the same issue or has some idea to how I could fix this, any help would be greatly appreciated.

 

If you need details on my PC, its on my sig.
