On a Windows machine i am using hwmon to check my amd gpu memory overclocking. If there are memory errors shown on hwmon then i reduce memory clock until there are 0 or near zero errors. I know that gpu can still work even if lot of memory errors are prodoced and there are no other signs than hwmon indication. Tho I never do that on windows rigs. how to do mem overclock on linux? should i push cards as far as they dont reproduce bad shares on miners?
I have swaped from windows to linux, i have put all cards to 2050 mem clock. But i know that 2 of the card had errors on windows if pushed above 2000. but from linux side everything looks good! Can i leave it that way? Or are there some ways to check those errors? I am on hiveos.

With HiveOs probably you can squeeze more from your cards. Linux handles your cards much better than windows albeit it uses 5% more power in term of TDP power consumption. I have the only Linux rig with Rx 570 8Gb cards Sapphire Nitro+ and I have pushed the memory clock to the maximum at 2250 and everything is working well so far.

2250, why not, probably 4G elpidas, also we don't know what timings, you can go that high with slow timings with hynix, and have lower hashrate than with 2000mem and fast timings. Also windows hashrate is a bit better, drivers i guess, power consumption approx same, he is lying. He just like his os, dunno why push it onto other. I'm also very interested in real answer to your question.
