You need to do a diagnosis to determine the cause. If the same problem appears on a separate computer with the stock settings, then warming up the memory will not help you.
On the contrary, you can break the video card.
I had a similar case, the video card passed the furmark tests, but an error occurred during mining.
Check it out in the game, for example GTA 5.
yes i tested on different location & also checked on my personal computer too. same problem everywhere. tried with stock bios settings too.
