RX 560 4Gb not giveing results

[tasos-e]

Hello everyone and thanks in advance for the support
I carefully read other post having related issue.

I have an ASUS RX560 with 4Gb ram on a i5 system with 4Gb ram wit Windows 7 64bit.

Since the new Monero algorithm my i5 can mine ok,
but
the GPU does not give any results. It keep saying "New block detected" but never gives results or crashes.
I get "GPU driver stopped working and rebooted" messages from the system.
Tried all drivers from 17.30 to 19.3.1 but all work the same way (or better do not work).

What more info shall I provide?
