I have a potato Asus PCIe2.0 with a RX580 8g (I7 12g ram) (driver fixed)

I'm finally using W10 after 7 was only giving me 1/3 hash I should have for a year (yes, I'm stubborn)

now, I'm getting the 28+hash I should have had instead of 8-9 at least, but...

I'm on 5.9d AND 21.11.3, but still have to use ckernal 0 to get it to work and that gives me abt 7-10% stales!

Is this normal? Even with the low hash before I never had this high a stale rate, and didnt have to use the ck0 until recently (on my old miner version with no NEW win 7 updates or drivers)

Thanks for any ideas or help!!
