Got cuda exception in [trexInitializerM, 194], unspecified launch failure errors for all cards after upgrading from 16.2 to 18.2
Disabling core and memory overclock didn't help.
Asus Phoenix 1063, Win7 SP1, Driver 451.67, core voltage 700mv (732mv also didn't work).

Code:

start /b /w /HIGH t-rex --devices 0,1,2,3,4 -a kawpow --mt 3 -o stratum+tcp://rvn.2miners.com:6060 -u wallet.worker -p x --log-path logs\t-rex.log --cpu-priority 5 --temperature-limit 80 --temperature-start 60 --temperature-color 64,72 --exit-on-cuda-error

Removing -mt also din't help

16.2 works perfectly with

Code:

-lockVoltagePoint:0,700000 -setBaseClockOffset:0,0,152 -setMemoryClockOffset:0,0,500

Which builds did you use for 0.16.2 and 0.18.2? My guess it was CUDA 11.0 for 0.16.2 and CUDA 11.1 for 0.18.2. If that's the case, then you either need to update the drivers to 455+ or use CUDA 10.0 build as it has lower driver requirements.
