I've been experiencing black squares in certain areas in games using a Sapphire Vega56 Pulse. Since this issue has not been resolved by returning and buying a different card (serial numbers different, hynix instead of samsung aswell :/), i'd like to hear some opinions on this. 2 different systems were used to test and reproduce this issue:
ASUS Prime Z270-P (bios 1205)
2x Kingston KHX2133C14/8G
650W Focus+ Gold (Fixed version, contacted their support)
Phenom II X4 965
2x Crucial Ballistix Sport
Same PSU and drives
iiyama G-MASTER GB2488HSU (DP)
Samsung SyncMaster S24B350T
Problems happen on all available drivers, latest tested: 19.8.2
Windows 10 x64 Edu 1803, also tested on 1909.
Issues happen on both displays, if one is disconnected, they still happen. I have tried downclocking by 10% and increasing powerlimit to +50%, no effect.
Here is a video of the issue:
First 2 seconds is pretty noticeable in the password field, please watch on 1080p60fps.
I am completely out of ideas, will try to get my hands on another psu.
PS: Forgot to mention, everything works using my older RX470.
