Can't find nonce with device [ID=1, GPU #1], cuda exception in [generate_dag_normal, 123], unspecified launch failure

T-Rex crashes instantly if Memory tweak mode is activated with the following error: "Can't find nonce with device [ID=1, GPU #1], cuda exception in [generate_dag_normal, 123], unspecified launch failure)". I have tried different memory tweak modes (from 1 to 6).

I suspect it's BIOS related, but I do not know which setting to change. 4G Decoding is enabled, PCI-e Gen is set to '2'.

Did you check permissions? At least in Windows systems you need admin permissions. Sudo/root for you then.
You should also check this issue: #78

Thanks for your reply. I was able to solve the problem. It was not permissions related. Apparently I need to reboot my rig after every change in OC. Doesn't matter if I OC if the miner iis not running, after every OC change a reboot is needed, else it will error out.
