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.
This has been an issue right after i received my first card, exactly the same issue with the replacement card. This also happens in Planetside 2, as seen in the video after a few seconds. Weidest thing about it is: The dots blink at the basically same position, even with the replacement card.
If it really was the PSU, i'd be more random and dependent on current power draw, which seems unrelated to this issue.
