Hi guys,

I'm starting my mining rig, and I got my hands on a RX 480 8gb doing 26,25 MH/s @ 94W, using -gt 68, and the following settings on MSI Afterburner:

- Core voltage: -43 (1081 mV)
- Power limit: -15
- Core clock: 1140 MHz
- Memory clock: 2115 MHz

Temperature <60º

Did I reached the maximum without BIOS modding the GPU? Or how can I maybe improve that?

Yes you can get more add -mt 1 or -mt 2 and add -rxboost 1.better start with mt1. you can go down core voltage to 900mv for better power consumption and less heat. without mod rx480 will give you 30mhs.

As I run as administrator, phoenix miner just shut down automatically, what could that be?

Share your bat file.
if it is shut down just double click and see what happens.

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

PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal XXX -proto 3 -tstop 67 -tstart 55 -mt 1 -vmr 25 -log 1
pause

I manage to run as administrator, and found the vmr value of 25, but no hashrate improves so far

ok last thing left to do reset afterburner or unistall it then give -cclock 1150 -cvddc 950 -mclock 2100 -mvddc 950. 950 mv is high ofcoruse just test then you can decrease it, if this not helps then only modding bios left. what is your driver version?

THNKSSS, now I'm at 29,280 MH/s, at 75W 55º, awesome, but I'm getting some memory errors, like 1 per min, is that a problem?
