I would like to share my experience with RX 470/480's
My settings:
Win 10 1703
19.4.1 drivers
No MSI Afterburner installed
No Wattman installed
Claymore 14.7, faster than PhoenixMiner
AMDMemoryTweak
OverdriveNTool 0.2.8
All Gpu's have modded straps, mix of 4Gb/8Gb
Notes on Claymore Straps:
Strap 1 Works best on all my Samsung memory and some Elpidia
Strap 2 Works best on Hynix and some Elpidia
I use rxboost 21 in Claymore (most stable for me), changes the tREF to 25 when viewed with AmdMemTweak.
Here is the order that I do everything:
1. Set all settings in OverdriveNtool/AmdMemtweak (it works the same) core/mem/volts/fanspeed
2. Start Claymore with rxboost 21 and strap x (see above)
3. I let Claymore run for about 5 mins (The hashrate is not max yet)
4. I then toggle the timing level in overdrive/amdmemtweak from 0 to 1 and click apply
5. Wait about 15 seconds and then change the timing level back to 0
For some reason the toggle increases the hashrate for all my cards (not sure why, since I put it back to 0).
https://i.imgur.com/ZaAhHPM.pngI have a 10 gpu rig hashing at 313.9 Mh/s using about 1416 watts. I am still working on getting the power down but each card is using between 115-122 watts. I know I am not breaking any speed records and using more watts than some. I just wanted to share my experience with everyone.
I hope this helps,
