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.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..
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
maybe try with 1 thread. W8 is ok, play with intensity.
I believe the problem is definitely not in your miner, I've tried every other miner and still, those STRIXs are hashing better with SRB
For Heavy I reached better results with only 1 thread and increasing intensity (around 57~59). Memory bottleneck is huge for Heavy algorithm. Around 770H/s with these settings.
If you can't reach similar results with these settings, your problem probably is related to biosmod and/or driver and/or overclock.
I'm not a genius like Mattthev, but I have good biosmods. Contact me if you want it.
confirming 770 h/s with I=59, W=8, T=1. and AB at 1230/2000 plus underwolting -48. thanks a lot! but still far from good
Great!
In fact, its far from the 8GB cards, but its because the huge memory utilization by Heavy 'cause the threads have size doubled compared to V7. I think we can't improve it more.

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. Few of them are Elpidas and rest are Hynix AJR. 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.
At lastest versions, 1150H/s in my RX580 8GB at 1310/2010 (940mv 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. Few of them are Elpidas and rest are Hynix AJR. The best that worked for me is I=59, W=8, T=1.
