Hi!
Ive just created table with hashrate and power consumption for most popular amd videocards, please help me fix it.
PM me or write here if have another value(s) for any card.
----------------------------------------
Model Sol/sec Power
7950 270 250
7970 292 270
R9 270 180 180
R9 280x 323 300
R9 290 340 250
R9 290 flash to 390 370 250
R9 380 200 200
R9 390 411 250
R9 390x 440 280
RX 470 4Gb 299 150
RX 480 330 150
R9 Fury Nano 435 275
R9 Fury X 455 275
R9 Fury Nitro 470 275
Model Sol/sec Power
7970M 2GB 145 100
A 7970M is equivalent to a 7870 desktop clocked at 850/1200 and I run these at stock speeds as my laptops cooling power is limited and the memory will not clock even 5 more Mhz
Settings for mining are all standard but intensity is set to -i 3.
[EDIT]
I am also running drivers 17.3.1, sometimes mining will only start on one card or one of the cards is very low, around 50 sol/sec and to fix it:
1. I stop mining.
2. Stop MSI Afterburner or any monitoring software I have.
3. Enable Crossfire.
4. Disable Crossfire.
5. Startup Mining and I have full speed on both cards again.
I have never tried re-enabling my hardware monitors as it just adds complexity I don't want to deal with.
