my ASUS STRIX rx570 4gb cards, wouldn't go more than I=29, hashing at 500~600 H/s, no matter what clock and memory settings I put in AB. what can be the problem?

at the same time, some of my RX470 8gb nitro+ are hashing at I=50 and 850-950H/s on one rig, and I=41 and 750-800H/s on the other..

Contact Mattthev, he'll sort you out with some great memory straps to flash your GPUs with in case you haven't got decent ones.

I assume you've set your intensity, worksize and amount ot threads properly?

no, how can I reach him? here?
well, for my STRIXs if I go more than I=29 rig crashes, plus if I leave it at I=0 for auto, it also makes it I=29.
as for worksize and threads, optimal I guess is w=8, and T=2 so I keep it like this

Is your BIOS modded? What are the stuff that's modded?

Heavy algo is limited on 4gb cards. I could only do 800 H/s on 4gb on Heavy while it does 1030 on cryptonight v7. (same clocks/volts)
Few of them are Elpidas and rest are Hynix AJR. For Heavy, the best that worked for me is I=59, W=8, T=1.

8gb cards should be able to do 1000-1100 on Heavy algo.

yes, bios modded, 1500 straps to upper.
my nitros + 470 8gb do around 950, but on one rig they refuse to go more than I=41 so they hash at 850
