hi to all! i'm new in mining in general, and naturally, i need some help.
-i'm italian, and sorry for my english!-
I have a mining rig with a rx 480 and an old motherboard (ASUS P5N-E SLI) with and old CPU (intel Q6600), 2gb of ram, that runs with EthOs 1.1.1.
originally, the video card run at 23mhs, after a bios mod (timing strip, thanks to all comunity, i've read a lot of threads that helped me) actually i run 26-27mhs.
at the wall, the power draw is 207-213w, and the card temperature is about 52°C
the question is: i'm doing all correctly? i read in this forum somebody that runs 29, 30mhs with this card, with the same power draw, and my low temps makes me think that i'm not using all the power of this card.
maybe the motherboard is too old and pci-ex bus is too slow? is there something wrong with bios?

I'm running the same card, getting 30.9-31MH eth + 330-340 Sia from 185watts at the wall (complete setup with 1 card, card is pulling around 130-135 watts itself from wall).
settings are Bios mod with the 1750 memory timing settings at the 2000 setting.
1180core clock, 2250 memory clock, 925mv on both, hope this helps you
It actually crashed at 925 after just over 24 hour period, so trying 930mv now on both.
mem 2195
ptune 20
hashrate 27 Mhs
Maybe the problem is SO. Are you running in windows, with your hasrate?
Can you pass me your bios?
I did some slight Bios modding and the card is running stable at 29.5-29.9MH/s and pulling 110w from the wall with NO mem errors.
After some further testing I got it to 30.7 MH/S pulling about 115W from the wall at a cool 57-60C (50%-60% fan speed at room temperature). This runs more or less stable, however there are noticeable mem errors. Still need to test and tweak this over a longer period of time.
Most of them can only 2175-2200.
Just a question of luck.
If you OC memory too much, you can see low hashrates on high clocks.
Definitive data is slowly dropping memory controller load on gpu-z, when mining.
So just reduce memclk a bit and check again.
