Hey there
I'm sure what you mean by "stuck on bios" though??
(FYI, this statement actually makes no sense at all probably, because if the BIOS failed to init, (actually the VERY first thing when you power on a PC, before the CPU, or motherboard), then you would not even know that RX560 existed in your rig.

FYI, the reason the very first thing in a PC that completes init is the GPU, is so the monitor is able to show the user what happens next, (the mb init and boot up etc).
This is of course not always entirely true, if you have multiple GPUs for example, because the BIOS on the motherboard only waits for the first GPU to complete init, then it un-pauses and runs it's own init sequence.

But when you say "overclock", that implies you know what the default clock is to start with, and equally the limits etc.


One way to find that out would be to use GPU-z, which will display the defaults, and the current values.

Like anything, there are limits, those can vary by vendor, model, etc, so one way you could find out about your card, (for sure, rather than believe what people might tell you), is to use ATIWinFlash to save your factory BIOS, then open it in PolarisBiosEditor.
Left pane, second box down, "PowerPlay" there will be a value for "Max Memory Freq. (MHz)" and whatever value you have in there is the absolute maximum the card will accept.

I could be wrong, but the RX560 is not such a common card in mining rigs, and I mention this because all the example batchfiles you see posted, are actually specific settings for specific cards, so don't assume you can use for example, RX580 clock limits (2250) on the RX560.

Maybe you can, maybe you can't, check for yourself on your cards, as above, then you know for sure.

Just out of interest, what hash rates are you seeing on the RX560, with what settings, (post your batchfile).


Post a bit more detail, if you need help, problems you're seeing, expectation not being met, detailed info on hardware, enviro,  drivers.

Good luck.
