Just started mining heavy algo for the first time on one of my rigs (RX 570).
Used to have ~950h/s per card on normalv7, now ~725h/s on heavy. Can somebody confirm this is about right? I set intensity to 0 to start with (had it set at 56 on normalv7 but that crashed almost instantly on heavy - what approximate value should I set it at in heavy mode? Half that?).

4gb cards? if so 20-25% reduction in hashrates. It's 59 for me, single thread. CN-Heavy doesn't like dual thread for 4gb cards (performance is lower than single thread)
8gb cards actually got a boost in hashrate by 5-10%

Aha - so I am using double threads. I'll try single threads and revert to previous intensity, see what happens (4GB cards indeed). Thanks.

Would I keep double threads and half intensity for Vega64 cards?

You can keep double threads for Vega. 14xx is the hashrate I get. Intensity 56, dual threads. Although Cryptonight-Heavy is weird. See my previous post 1-2 pages back. I did get 1560 H/s on similar clocks/settings. Can't keep it sustained though. perhaps it's just a bogus hashrate display

RX570 8gb + Vega 56 8gb.

Below is mine for 6xRX580, GPU0 is Hynix rest are Elpidas. (4gb cards)

hello,

used Cast_XMR for heavy and "only" got 680hs with my RX 570(stable last 24h)

now i tried SRBMiner and got 750hs with 60 intensity, 8 worksize and 1 Thread - but the miner crashed and card resets after 5 minutes. HWInfo dont show Meory errors or anything else - any idea whats the problem?

Reduce intensity to 59 and mem clock. I observed GPU settings that might work fine with CN-V7 might not play well with CN-Heavy.

How much juice do you give the core to run it at 1525?? That's pretty high...
