Question Why does my GPU work fine for mining but not for gaming ?

[Tonge]

Hey everyone, I bought my 1080ti and when i wanted to put in the PC build for gaming it just kept crashing on every game. Then i tried the heaven benchmark and it just crashes in 3 sec after starting. When i put the benchmark on basic preset it passes but sometimes during the test it freezes for a couple of seconds. Tried some memory testing software (OCCT and GpuMemTest ) witch passed perfectly. When the actual crash happens it just closes the benchmark or game and windows continues to work fine. Never gave me black or blue screens. Sometimes when you enter a dark place in game you can see spots changing color rapidly like when the GPU is dead. Tried to put to put it to mine and its mining fine with good hashrate without crashing.

Why does the card work fine for mining but not for gaming ?

My pc build:

ASUS Prime A520M-A
Ryzen 5 5600x
Kingston Fury Beast (2x 16GB) 3200MHz
Samsung Evo 980 1TB
LC Power 650W LC6650M V2.31 80+ Gold

Here are some of the solutions i tried

• Underclocking core and memory frequency using MSI Afterburner
• Installing older drivers
• Changing the PSU up to 1000W
• Cleaning the GPU and replacing the paste.

I was wondering if there could be a solution here, maybe with reflow or reballing I'm not very experienced in that, or if the card is just dead.
Any suggestion would be appreciated, Thanks! 😀

Things to do:

Use Task Manager and Resource Monitor to observe system performance. Use both tools but only one tool at a time.

Observe while the system is idle, doing light work/browsing, gaming, and mining.

You will need to keep the Window open and pulled to one side of the monitor or display on a second monitor if a second monitor is available.

Determine what system resources are being used, to what extent (%), and what is using any given resource.

My thought is that gaming requires ups and downs in wattage. Mining is likely a much more steady wattage demand.

The PSU may not be able to keep up with varying power demands.

How old is the PSU? It may be nearing its' designed in EOL (End of Life) and starting to falter and fail.

You can also look in Reliability History and Event Viewer for error codes, warnings, and informational events that correspond with the crashes. Could be a clue therein.

Far from any real experience with mining, but I would suppose you bought the card used?
Was this card vBIOS flashed for mining? If that was the case, would it even load 'standard' (gaming) drivers?
