Hello,

Im new to GPU mining and have since 2 days a single GPU.
Because out of stock, the other 3 GPU's are coming next week.

I got the RX 580 Nitro+ 8GB with Hynix memory.
I have flashed another BIOS on it with custom memory straps.

Now im dealing with something, electricity is expensive in my country so im trying to get the best tweaks for high mh/s and low wattage usage.

Settings 1:
I'm starting the miner without .bat, just with the config settings.

Msi afterburner
Core clock: 1100
Memory clock: 2210
(no other tweaks via afterburner)

Result 1:
Dual mining ETH + DCR

ETH: 29.6mh/s
DCR: 445mh/s
Wattage use (+ mobo, cpu, ssd etc.): 160W
Temp: 42 degrees celsius.
1 memory error in 12 hours


Now I saw some other people getting 30mh/s + and 800mh/s + with the same card so I googled and found a .bat file setting.

Settings 2:
Starting the miner with the .bat


Result 2:
Dual mining ETH + DCR

ETH: 30.3mh/s
DCR: 1000mh/s
Wattage use (+ mobo, cpu, ssd etc.): 210W
Temp: 48 degrees celsius.
sice 3 hours no memory errors.


Can anybody help me to lower wattage with a bit, but somehow keep the speed? And please be not so hard with me, I do not understand everything.

Thanks guys!

to lower the consumption you will need to decrease -cvddc and -mvddc

Go reduce and check the amount of memory errors.

Set -cvddc at 875 and remove -mvddc.
That's all you need.

You have bad memory timings, with good ones you would be getting that speed at 2000 -2050 memory clock.
First you need good timings if you want decent speed at low clocks.

Wow, same speed, 3'C lower and 10W reduced.
No memory issues yet, I will test this all day.

Thank you MATHReX !
