With the new version of Claymore, what WIN10 version (updates) are you using and what are the best drivers for RX 4xx & 5xx cards?

I am running windows 10 1803.
rx570 4G @ Driver 19.4.1
Original BIOS

I've tried straps 1-5, and POL4Hx@1900.
Windows crashes immediately.

Without strap, everything runs fine, but @22MH with compute on.
I use wattman not afterburner.

this is not a good result, you have to run this card around 30Mhs... depends on the RAM type, but this is the level you have to reach

Well, he said he's running original BIOS...

I see that

but he has tried something with the straps and is unstable, obviously
With this last Clay version the bios can remain untouched (flash) but there is a solution to play with the straps and drivers, so I'm returning on my first question, "the best drivers for RX 4xx & 5xx cards?"

I tested it by installing amd driver 19.4.3 and after that Claymore driver ("Ethdcrminer64 -driver install") as an admin on cmd prompt then added "-strap 1" to end of bat file. I did over- and underclocking in AB. (RX4?0) . Worked perfectly.

I've figured it out.

And claymore should have give clear instructions in the readme.

1. run cmd with admin rights
2. cd to the ethminer folder and run: eth..64.exe -driver install
3. restart
4. overclock your AMD cards as usual.
5. now add -strap to your start.bat and everything will be ok.

Nothing has changed for me. It's the same hashrate (29.3) as 12.0 on blockchange driver and a modded bios.

Yeah, it doesn't change anything if you already have good straps on your modded bios. It just makes it easier.
What cards are you running and getting 29.3? did you try different straps between 1-5? and clocks? higher than before?
