these guys with rx 570/580 hashing below 1kh/s i think are doing it wrong. check your straps and oc.

all of my rx 570 hashes above atleast 1kh be it 4gb or 8gb. the only problem i have is micron, which i think is the worst in cn variants.

Agree, matches what we found as well. Haven't really found any card stuck below 1kh/s, except for Micron mem where we've been stuck around 860 h/s on some cards whatever we try for straps and clocks. Samsung by far the easiest, Hynix often also just a copy of lower-to-higher straps. And, I'm really not that good with straps, I should add.

Great job TeamRed!

Read every post here, testing rig for about 8 hours without crash. Now trying to fine tune.

Here is mixed rig (1 x rx570 4GB Elpida, 2 x Vega 56 referent + 1 Vega 64 Asus Strix)
Vega 56 hashing about 2000 H/s, Vega 64 2240 H/s). Vega 56 have low clock and memory 1408/1088 because on SRB is overheating and crashing on more clocks. Vega 64 is on 1520/1100.

Funny thing about RX570 is that hashrate of RX570 somehow depends of configuration on Vega cards.

When i first start miner (without --cn_config) RX570 Nitro + (Elpida) hash 920 H/s with timings 1200/1980.

Than I experiment and put on RX570 7+7 (default was 8+7) and lower clock and memory to 1225/1940 (as user Dragonmike recommended). Playing with OverdriveNtool when hashing, been able to get 942 H/s with 1200/1920 but i think that time i put Vega 56 to 15+15.

When i restarted rig, RX 570 hash just 880 H/s? Try appy OverdriveNtool with same clocks as before 1200/1920 but still 880 H/s. Than i apply 1250/1980 and still 880 H/s. mV for clock and memory 900 mV.

What am i missing and is it possible and where to delete kernel files to make automatic initialization of the cards again?

That sounds a little weird. I dont know if you restarted the miner or rebooted the rig in between runs? One issue we have (which Im a little ashamed of tbh) is our unclean shutdown. It has led to me losing perf between restarts at times. Can you reproduce your test, i.e. whenever you run the 570 only after a clean reboot you hit ~940 h/s, but 570+Vegas after a clean reboot and its lower for the 570?

Yes, something with RX570 4GB is weird.

Tested a little, two times rebooted the whole rig and whatever clocks applied max hash is just 880 H/s.

Than rebooted third time, and my Task Scheduler automatic run SRB Miner.bat and apply Overdrive profile and my RX570 hash 910 H/s in V8 which is normal to me in SRB Miner for this card.

And than weird again :-) start TRM and RX570 hash with same 910 H/s like in SRB :-) Bump from 880 to 910.

I leave it that way from last night almost 24 hours stable running:

Here is this (for me) stable Setup of mixed rig with 730W from the wall (-50W and + 300 H/s):
Win 10, Adrenalin 18.6.1
GPU 0 (RX 570 4GB Elpida Nitro+) 7+7 core 1180/850 mV memory: 1980/900 mV. One click strap.
GPU 1 (Vega 56 ref. with 64 bios ) 16+14 core 1408/950 mV memory: 1070/950 mV
GPU 2 (Vega 64 Asus Strix) 16+14 core 1520/920 mV memory: 1100/910 mV
GPU 3 (Vega 56 ref. with 64 bios ) 16+14 core 1408/955 mV memory: 1088/945 mV

As you can see, Vega 56 ref with Samsung mem can in your rig hash much better with more clock on core and mem, i must lower it because rig is in small space and overheating. Waiting for the winter to come :-)

I tested intensity and found that Vega 56 Reference even on this lower clocks still more like 16+14, than 15+15.

Change your Vega 56 back to stock.

I get on 16+14 1500 clock and 950mem 2050h/s
