I want to build a second rig, but i want it to mine ethereum to different address. Do i need to make a new email for that or i can configure each rig to mine separate address in the same email account ?

Hello, i got a problem with second gpu(gpu1) no matter how much i oc it just wont increase the mh/s.

I tried :
Swap the gpu 0 and gpu 1 position in motherboard, still 1 card wont increase mh/s
Reinstall driver
Reflash bios, even when default bios 1 card just wont change mh/s
I check in gpu z, both card are overclocked

The card which i place on the first pcie always can increase mh/s, but the second card which i put in second or third or fourth slot wont increase mh/s.

This is my start.bat :

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 asia1.ethermine.org:14444 -ewal 0x43aee44a72d9bf2dcdb61caa5178fe93fce68a3c.eth1 -epsw x -r 120 -tt 80 -tstop 85,85 -mport 192.168.0.104:3333

Thanks guys
