i try to use -cvddc option in start.bat file to allocate 825mV to my rx470
the core voltage in bios is dynamic
but it does not work and with the option in start.bat file still GPU-Z show 1000mV
on the wall same
i have to use a program such as sapphire trixx to undervolt each card for -175mV
no reason found yet!!!
Show your .bat file please.
Maybe it will tell someone the reason.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal walletXXX.workerXXX/email@email.com -epsw x -mode 1 -ftime 10 -cvddc 825 -mvddc 900
Sorry, It looks correct to me.
Maybe someone else will see something I don't.
That's pretty much the way I use them, other than I also set both clock and voltages.
The other difference is I have mine in the config.txt file and not on the command line, although I don't
see how that should make a difference.
