sorry delle54, you are right,
all 4 cards 480 8gb, and useing this command line
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ZecMiner64.exe -zpool zcl.coinmine.pl:7007 -zwal ybelevi.4801 -zpsw x -allpools 1 -tt 55 -ttli 75 -tstop 83 -fanmax 100 -fanmin 60 -cclock 1280 -mclock 1850 -powlim 0 -colors 1
first one of gpu freeze then miner restart after then crush, any ideas?
THX for the detailed info about your system. My crystal ball tells me you may have to do the following:
A workaround for rigs with mixed cards (Polaris and old cards): start two miners with "-di" option, one for Polaris cards and second for other cards. Use "-mport 0" option to disable port for remote management and avoid red message in second miner.
I will fix it soon.
