Re: SRBMiner Cryptonight AMD GPU Miner V1.4.7

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

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

My Strix 570 4GB is performing around 980H/s at 1230/2020 in Cryptonight V7 and Cryptonight Classic. Intensity 54 and 2 threads.
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.
