Best Stable Settings for Sapphire RX 470 OC 4GB (Hynix) Versions (tested on 10 cards) :
Results : 26 Mh/s @ 70W (GPU-Z reported) and ~70C (measured while Eth Sia Dual mining with Claymore 6.2)
Steps to reproduce :
Install drivers ( im using 16.8.2 no issues ), get AtiWinFlash and backup your bios someplace safe
Using Polaris Bios Editor open your bios, Copy paste the 1500 strap timings to 1625, 1750 and 2000, no need to touch anything else, and save as a different file
Use the Win 7 Fix (works in Win 10 but you have to disable signatures at every boot, so kinda painful), boot in safe mode and patch the Drivers, restart pc, load Wattman and use the following settings:
Core : 1000Mhz/818mv (half my cards are stable 1000/800 but stick to 818 to be safe)
Mem : 1850Mhz/850mv (some may do better but this speed is generally safe)
These settings are optimized for lower power draw/heat primarily because I have 750W PSU's only and its pretty hot in India
I was initially really disappointed with the RX 470 getting 21.5 ish, until the wonderful Polaris bios editor came along.
With these simple, easy to reproduce settings you will be able to get the maximum out of your cheap ass RX 470's without needing extra cooling, and these settings have been stable on my 2 X 5 card rigs drawing 510W each for 12 hours now
If you are on Linux, you can hardcode all settings into your bios and they should work on any Sapphire 4GB RX 470 ( also theoretically any RX 470 with Hynix mem )
Higher hash rates are possible, as shown by but they would come at higher power/heat
Shoutout to for his regular updates, reading his posts helped me get my rigs up and running
Mining equipment metrics are calculated based on a network hash rate of 5,527 GH/s and using a ETH - USD exchange rate of 1 ETH = $ 12.74. These figures vary based on the total network hash rate and on the ETH to USD conversion rate. Equipment cost can vary, block reward is fixed at 5 ETH and future block reward reductions are not taken into account. The electricity price used in generating these metrics is $ 0.12 per kWh.

Nice! I'm a miner too, always interested to read the posts like this ;D
Nice build, it might be time to throw out the milk crate and follow your lead.
If you haven't already been mining, be careful with using the claymore dual miner, it runs the boards hotter, costs more energy of course since it's dual mining and after dual mining fee may not be worth it.
I followed advise from a couple other miners and went back to single mining. Your temp stats look good though.
Nice
