I'm testing v1.29 on HiveOS with two rigs on 2Miners

one with Nvidia Only, all good, whether I use Xintensity 448, 1024 or 3108
and another with one RX5700XT and this one will only mine consistently if I use Xintensity 448 or below.
Above 448, it ends up crashing and upon restarting, the Dag is reported corrupted, and it enters a miner restart loop.

Would there be a way to allow my AMD card to mine consistently with a high intensity ?

Thanks
