2175 MHz memory overclock is very high for a Bios modded RX 570 4GB card, which have slower memory than 8GB cards. My Sapphire Nitro+ RX 570 4GB card has Hynix memory and I can only overclock it to 2020 MHz before it starts producing tons of memory errors. It also depends on how aggressive the Bios mod timings are.

17 of RX 570 Sapphire pulse 4GB OC with Hynix Memory was running perfectly at 1150/2175 and that is the max limit a Hynix memory does. Only 18th cards started behaving not well and crashing several times.

Still the new settings are running from several hours without problem, I guess I will pay more electricity with 1284/2100 compared to 1150/2175 as the hashrate is bigger with 1284/2100

I have a few mining boards with RX 570 4GB, so far I have been happy with following setup:

BIOS mod and
MSI settings
Core clock 1150
Memory clock 2175 for Hynix Memory.

Lately I had one card which crashed all the time if I did the bios mod with the above settings although is the same card. So what I did is to change the bios and the settings to

Core clock 1284 (actual core clock which any RX 570 GPU has default)
Memory clock 2100

Working well with 200-300 hash more in total for 6 cards in cryptonight.

I don't think I have overclocked too much but anyway wanted a bit of advice from other miners.
