Speed increase on BitTube/Haven/Heavy/Italo algos up to ~10% (depends of gpu)
Houston we have a problem! Cry

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

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"

Thanks for reporting these, i will check it out


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.

distinguished developer
one question
do you still support old pitcairn video cards ?
After the test of your latest version 1.7.0 I am at a loss?
srb 1.6.9 pitcairn 370 2 gb stelite v4 --- 485h / s
srb 1.7.0 ---- 226h / s
total failure

Confirming the problem Sad 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 Sad

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

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.
