Hi guys.

I got 4 cards Asrock RX 5700 Challenger OC 8 GB and they start at around 50 MH/s on Ethash out of the box.

I'm on Windows. I loaded up the 5700 XT BIOS through MorePowerTool.
I'm using AMD Wattman to overclock. I've tried MSI Afterburner but it broke really easily. So it's Wattman for now as I'm trying to find correct values anyway. I can use something else later.

Without knowing what I'm doing, I got up to 51.8 MH/s (133 W) with these settings at Wattman and it's stable:
-12% power
1788 MHz VRAM
1610 MHz GPU
913 mV

I see people mentioning lower voltages, such as 800 mV, and lower GPU clocks such as 1300 MHz, and I know I should overclock the memory more. But when I go outside these values I quoted, it all breaks, Wattman resets itself to default values.

So what am I doing wrong? Any help is appreciated, especially if someone is using the same Asrock RX 5700 cards and can show me the correct numbers. Thanks guys.
