vram error (sort of) on some games RX 580 2048sp 8gb from aliexpress (tho no vram error first time)

[ookami772005]

like title is saying started to get vram issues once more than 4gb on resident evil 4 remake my RX 580 is gigabyte btw
but on doom eternal it worked normally with 6gb vram usage tho had to increase ram pagefile and it ran smoothly just from time to time drop to 5 fps for 5 seconds
i checked GPU Z and when i clicked on look up button it took me to RX 580 2048sp 4gb ver
and when i compared info it's similiar to RX 590 8gb ver any help?
DONT TELL ME WHY I BOUGHT THIS FROM ALIEXPRESS FOR CHEAPER PRICE BECUZ I LIVE IN ALGERIA AND I AM 18 YEARS OLD
i also found discord flickering icon for some reason... after trying to play RE4 remake even when D3D error was there but now it's gone
is it dying? plz tell me it's not i am nervous

If you clock your card lower, is the problem then away?
