[Vega 56] Hard lock when doing bruteforce attacks
#1
Greetings!

As the title says I'm experiencing a pc hard lock only when doing bruteforce attacks.

My current GPU is a Vega 56 with driver version 21.8.1. Tried running it stock, undervolted, power target reduced , DDUed the driver, etc. and still experience this.

One thing I noticed was the GPU clock suddenly spiking to 1556 Mhz and power consumption going down from ~110w to ~56w. The GPU clock then stays locked there and a couple of seconds later the pc completely hangs. 

This is very strange as I have no problems what so ever with any other type of attack nor mining using a highly undervolted setting, as well as playing some games with a custom OC + UV profile.

If anyone experienced this and knows where should I look, I would be much obliged if they could share their findings.
