Hello,
I have 3 RX480s that I've been mining (ETH/SC) w/Claymore in my gaming rig, to give me time to learn the ropes before building dedicated mining rigs. They're all still at defaults, but I'd like to:
- lower their power use, and
- see if I can bump their hash rates up.
The cards that I'd like to explore modding the BIOS on are:
- XFX RX 480 RS 8GB 1288M XXX HS BP (RX-480P836BM/RX-480P8L),
- PowerColor RED DRAGON RX 480 8GB GDDR5 (AXRX 480 8GBD5-3DHD), and
- Gigabyte RX 480 WINDFORCE 8GB (GV-RX480WF2-8GD)
I've read through this entire thread. You're welcome to tell me to RTFM again, but I'm not entirely comfortable that I wouldn't brick the cards. I've looked at the default BIOS roms in SRBPolaris, and they're all recognized. Is there a source on these models on what settings ppl have found ideal? Do I just need to experiment, and hopefully not destabilize the rig repeatedly?
Any tips or resources you can point me toward would be greatly appreciated!

P.S. In case other device, etc. stats matter:- MSI GTX 1070 X Gaming as my main GPU (gaming),
- SAPPHIRE Vapor-X HD 7950 3GB 384-Bit GDDR5 mining (b/c I haven't gotten rid of it yet).

- MSI Z87-GD65 Gaming motherboard,
- i7-4770K (3.5 GHz)
- 32 GB (G.Skill (4 x 8GB) DDR3 PC3-19200 2400MHz TridentX)
- Windows 10 Pro
- SK hynix 500GB SSD
- Barracuda 3TB x6 (RAID5)
To mine ETH you need mostly memory speed. So you have to copy lower memory straps to the higher ones, increase memory speed and lower core speed a bit to reduce power consumption. all this can be made with SBPolaris.
About the 1070, you can mine ETH with it. Check memory brand to see how much you can OC.
I think most people use the 7950 to mine ZEC.
You don't need all that RAM.
Also, be aware of your PSU, because there's a lot of power hungry GPUs there.
