So for some reason my memory clock has absolutely no effect on my ETH hash rate.
Everywhere I read, everyone is saying that its the memory clock that has most impact on ETH hash rate, but I see absolutely no increase between 1750 -> 2150.
The only way I'm able to bump up the hash rate is increasing GPU clock, its a very slight bump, going from 1050 -> 1125 gives me a bump of 0.75 MH.
Using Sapphire RX 470's 4GB Nitro (Non +).
I tried modded bios, 1500, 1425 & even 1375 straps. I'm undervolting GPU, but not touching the memory voltage.
But no matter what I do memory clock has no effect on hash rate.
What could be wrong and any way to fix this? Do I need to overvolt GPU memory?
