Hello

I found a bug with the new startup monitor option
If you run benchmark-algos.bat, the startup monitor will kick in and restart the miner every 120seconds and the benchmark never finishes
The .bat file needs "--disablestartupmonitor" OR make sure that "--benchmarkalgos" always disables all watchdogs
edit: one more! benchmark-algos doesn't benchmark "dark" nor "festival"

So... My RX 574 + 100H/s (v.1.6.9 = 750-770   v.1.7.0= 850-870) - nice! But RX 564 lower on new version (v.1.6.9 = 500   v.1.7.0= 450) bad! All cards same options at two versions.

Confirming the problem On the RX560 cards there is big hashrate fall... (measured now on haven algo)
v1.6.9 = 613H/s
v1.7.0 = 501H/s
The settings, the driver version - all the same.
If I copy the kernel files, compiled on v1.6.9, to the .\Cache dir of v1.7.0, the RX560's hashrate is about 520-530H/s. But anyway - the problem is present

P.S. RX570/580 have some hashrate increase, is about 30H/s

what to do if you get compute errors?

also getting compute errors, can't shake them, on vega FEs, 18.q3.1-oct1 driver, Heavy

V1.7.0

+ Performance boost for BitTube/Haven/Heavy/Italo algos up to ~10%, some cards gained 1% some 10%, i don't have exact numbers, you should try it out and see.
Vegas gained the most, also i hope that i fixed the Ellesmere 8Gb cards problem, not reaching max hashing speed. If you had 1k+ on some earlier versions, you should be able to reach it now again but you MUST set fragments to 0 if you are setting it by hand, otherwise it probably won't reach max speeds.
And no fee increase because of the extra performance, it stays at ~0.85%

+ Some small optimisation gained around +10hs on my test Vega56 on V8 algo

Spot on:

Vega 64 :

Algo	1.6.9	1.7.0
Heavy	1550	1685
V8	2018	2035

Almost same power consumption


Thx doc !~!

Good for you if you had that speed on 1.6.9, continue using that version then

Thanks for reporting these, i will check it out

Could you guys try out other configurations, like change the intensity and fragments parameter?
Yes i know you would all like if always the same settings would work, but that is not possible unfortunately, one code has different effects on different gpu types.

For 560 4g try setting fragments in gpu_conf to 32 for haven algo (that was the value in the previous version), leave the intensity same for this test.
and clear the cache folder, don't copy binaries from older versions etc.
also please leave it work for minimum 5 minutes to get the 5 min average

EDIT:

Ok, my tests show this on Haven :

RX550 4G no mod :

Intensity : 15
Worksize : 12
Threads  : 2

5 minute average result

1.6.9
Fragments 1   : 292 h/s
Fragments 32 : 270 h/s

1.7.0
Fragments 1   : 322 h/s
Fragments 32 : 304 h/s

Later i will do this same test on my Rx560 4G and report back.

Try lowering you memory clock by 10mhs, and see if that helps

[Kgonla]

My firsts tests with RX 580 cards V8 algo:

v1.6.8 4gb = 1000 H/s
v1.6.8 8gb = 935 H/s

v1.6.9 4gb = 985 H/s 
v1.6.9 8gb = 975 H/s 

v1.7.0 4gb = 1010 H/s 
v1.7.0 8gb = 975 H/s 

for 1.6.8 & previous best intensity for 4gb was 61 & 116 for 8gb
for 1.6.9 & 1.7.0 best intensity for 4gb is 54 & 100 for 8gb

Also say that with newer versions the card connected to monitor is much more sensitive to background programs loosing more than 200 H/s in some cases when with 1.6.8 & previous was loosing at most 30 H/s

[dumada]

Looking at profitability charts something seems wrong, I went on whatomine and it suggested to switch back to ethereum , due to the power/hash combination of cnv8 vs ethhash.

Something is really off becase when i moved my rigs to ethereum from cnv8 my power use went up by 4 amps

that basically an extra amp per rig nearly.  that is around 1000 watts at 240V.

someone needs to correct the power use calculation used by the profit calcs . V8 uses more power than v7 but no where near close to ether as the calcs have it

I think you need to use your own power consumption to calculate. For me, ETH and V8 has similar profitability.

Bro, can you tell me you settings about RX560 - v1.6.9 = 613H/s, my cards only 550H/s

[doktor83]

Okay, so some of you said that the hashrate on Rx560 4g is lower on 1.7.0 vs 1.6.9 on heavy algos (said Haven) - HERE
I took some time and made some tests :

Both cards are without bios mod.
Before every test i used the 'reset' button in ODT , just to be sure.
5 minute average result taken, same card, same clocks same driver same machine same everything.


RX550 4G:

Intensity : 15
Worksize : 12
Threads  : 2

1.6.9
Fragments 1   : 292 h/s
Fragments 32 : 270 h/s

1.7.0
Fragments 1   : 322 h/s
Fragments 32 : 304 h/s


RX560 4G:

Intensity : 15
Worksize : 8
Threads  : 2

1.6.9
Fragments 1   : 349 h/s
Fragments 32 : 340 h/s

1.7.0
Fragments 1   : 354 h/s
Fragments 32 : 356 h/s


So as you can see i can't reproduce the huge -100hs drop you said. As a matter of fact, i can only produce + hash, not -  

[doktor83]

My firsts tests with RX 580 cards V8 algo:

v1.6.8 4gb = 1000 H/s
v1.6.8 8gb = 935 H/s

v1.6.9 4gb = 985 H/s 
v1.6.9 8gb = 975 H/s 

v1.7.0 4gb = 1010 H/s 
v1.7.0 8gb = 975 H/s 

for 1.6.8 & previous best intensity for 4gb was 61 & 116 for 8gb
for 1.6.9 & 1.7.0 best intensity for 4gb is 54 & 100 for 8gb

Also say that with newer versions the card connected to monitor is much more sensitive to background programs loosing more than 200 H/s in some cases when with 1.6.8 & previous was loosing at most 30 H/s

Ok so obviously your 8G has some issue, maybe the strap, maybe just a bad card.
Anyways. You lowered the intensities and get same or better results. That's what i call a win 
Probably lower power consumption with lower intensities.

[goran89]

On 1.7.0 I am getting better hashrate
my rx 580 4gb get about 10 H/s more on v8 (from 990 to 1000)
but my rx 570 4gb get about 40 H/s more on v8 (from 945 to 985)

For 5 cards (3x570 and 2x580) my hashrate went up for about 140 H/s compared to 1.6.9 with same settings but power consumption also increased for about 30W (from 630W to 660W).
Also my 570's are getting to much memory errors now, so I will need to lower intensity on v8.
For fast algo I am getting about 200H/s less compared to 1.6.9. with same settings.

play with fragments (its enough to try 0,1,2,4,8,16) and see which one gives the best results for that particular card.
also try aes 0,1 or 2 .
Fast algo is V7 variant nothing has changed in code for v7 and variants
my guess is that the default fragment value isn't optimal for your cards.

also in the next version i will also return the 'old' code for heavy, that was in 1.6.7, and some of you say it was better for you than the one now.
So with a new parameter (yes, again), you can choose which mode for heavy you want to use.

That way everyone will be happy
