SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[doktor83]

is it important worksize in config ?

i tried 8 and 16 and 12
i think no any effect. any idea ?

it is important.
Which algo?
Which gpu?

For me too. I have a Rig with 6x RX550 4G. I mine Monero (CN V7) with 34 Intensity. 8 or 12 worksize change nothing in hashrate. I get arround 2900 hahes with this config.

550 4g should be ok on V7 with : 27/12/2
550 4g should be ok on V8 with : 28/16/2

higher intensity doesnt mean more hash always

RX550 2GB
RX470 4GB
RX570 4GB

it will be wonderful if you write worksize values for the different graphic cards in readme.txt

With 27 for example i get only 2800 and if i increase the intensity step by step, then the hashrate increase step by step. So 27 is not the best value for me.
Hashrate is the same with worksize 8 and worksize 12.

I can't  because with the same card something that works for Joe, does not mean it will work for you.
You cards maybe cant handle the intensity Joe's cards can.

[samet_9511]

i know how to set intensity and threads.
i need to know only worksize. I always set 8 to worksize.

I have a farm with 35 rigs: RX550 2GB, RX470 4GB and RX570 4GB

These are my conclusions from lot of testings i made :

Rx550 is always 8 or 12 for 'old' algos, V8 is 16, that you have to test because again (and it is interesting), some say they get better results with 8, but others with the same card say they get better results with 12.
Rx470 and Rx570 is always 8 for 'old' algos, V8 is 16.

[doktor83]

OK, so after testing with 18.3.4 and V8 here is the conclusion :

Don't use 18.3.4 if you want to mine V8!

It's something in the V8 code that driver doesn't like, and probably not something i can fix.
I will put this info on the first page.

Also a google document maintained by users, where one can see tips for settings on various cards and algos :

have you tried auto intensity for 550?

also it would be nice if you could write your settings

no
for 2gb 1.6.8
550
   { "id" : 6, "intensity" : 27,  "worksize" : 12, "double_threads" : true},
 GPU6 :    504 H/s [T: 49c, RPM: 0, CC: 1050 MHz, MC: 1950 MHz][BUS:4]
560
   { "id" : 7, "intensity" : 27,  "worksize" : 12, "double_threads" : true},
GPU7 :    488 H/s [T: 53c, RPM: 2635, CC: 1050 MHz, MC: 1850 MHz][BUS:2]

for 550 4gb 1.6.7
   { "id" : 0, "intensity" : 54, "double_threads" : true, "worksize": 12},
 GPU0 :    416 H/s [T: 51c, RPM: 2833, CC: 1090 MHz, MC: 2050 MHz][BUS:1]
same 550\4 in 1.6.8 only 380-390 h\s

Haпишитe ecли нe cлoжнo кaкиe y вac 550? пaмять? и ecли oчeнь нe cлoжнo тaйминги)

WOWnero(CryptoNight V2), so CryptoNight V8 is CryptoNight V2?

yes lol

Hmm, testing with a single Vega56.  Was getting ~2035 with 1.6.7, now getting ~1630 with 1.6.8.  Tried both the Normal and Maxi versions, same results.  Using the 18.6.1 drivers, so not sure what to make of this 

Ok, figured out my issue.  I had intensity: 0 in the config, and specified a GPU-specific intensity (112).  Once I removed the gpu_conf section, it worked perfectly.  Don't know if this is a bug or a change in how inheritance works in the config files.

when you set intensity to 0, miner sets worksize, number of threads and intensity automatically

Yup, I knew that, but thought the gpu_conf section overwrote the global settings outside the gpu_conf section.

Hello doktor83

I have 1 rig 10 x RX570 8GB and 18.6.1 driver.
My OC settings: 1250 - 2130 - 925 mv
Intens: 56
Double threads on
All cards have same ram (Micron), and bios.

My problem is about hashrates, Some cards are constantly running at low hashrate. I wait about an hour the result does not change. Where am i making a mistake?

it should overwrite. maybe it really is a bug
