with core 1200 and memory 2100 i have 945~950
my problem is i do not know the range of values so i can test your great miner
is there any help or manual for it

For example if miner shows you 472 when you run it without any intensity settings (auto mode), you could try going up/down by steps of 8.

--gpu-intensity 480+480

 if hashrate is increased , increment more

--gpu-intensity 488+488

etc

test until hashrate decreses, or miner / system crashes etc. Then go back to the last value that worked for you.

you get the point

@doktor83 kudos for being one the first devs to add experimental support for big navi.

No luck on cn_gpu for 6900xt, gpu is hashing but not getting any accepted shares on pool. Thoughts?

Can mine cn_xhv with accepted shares, strange behavior, hashrate will oscillate b/t 2100-2600 until settling around 2400.
Tried varying intensities, gpu seemed to prefer using dual threads, but similar results with respect to oscillating for first minute or two after startup.

Yes i have actually, now that you mentioned cn_gpu, because i just remembered i didnt compile it the way i should have Smiley
Going to be fixed in next release.

I dont have a 6900xt so i couldn't test, but looking at the specs i think you could try running 3 or maybe even 4 threads.

Code:
--gpu-intensity 896+896+896

For settling the oscilations you could try the new-old thread delay parameter i added, --gpu-extra-config (check details in Help\Gpu_Tweaking_And_Boost.txt)

Can you test it on ETHASH, im curious about the results ?

@doktor83, did test on ethash and performance is in line with other top miners, ~64.1 MH/s. About the oscillations, I was already using your new parameter which did help boost the hashrate to the 2400. It's tough to know what delay is proper, seems the gpu eventually settles on most appropriate workload distribution due to the oscillating going away after a minute or two. Will be interested to see how SRB performs on cn_gpu after updated compilation, XMR_Stak gets around 5k h/s.

Great to hear that, maybe you could try using 2 threads on ethash ( --gpu-intensity 23+23 for example ). I think it should/could do better than 2400hs on XHV, have you tried the 3 thread stuff?
Contact me on discord i can give you a version with fixed cryptonight_gpu so you can test it

dok, tried the 2 threads on ethash, trivial hashrate boost from 64.1 to ~64.3. bus width and overall memory bandwidth will hamstring this card on ETH, was somewhat expected; whether or not the cache can help in some way is yet to be determined I guess.

Tested various multi-threaded configs on cn_xhv, best final result is still 2400 H/s.

Will reach out on discord for cn_gpu.

where can i see the default intensity that the cards are working with? (when in auto mode)

I try to mine with this miner xmr but I get this error this is my settings for batch
SRBMiner-MULTI.exe --algorithm randomxl --gpu-intensity 10 --pools-file pools1.txt --wallet 45hErb81bKRJZAvL8o8jodB6TQVZvNb8N1K97xh24GBv7Y7UNyvcAfR5M6BjFw1xyocVB5bf2gGzZf5 pPppHnbbDD5aELfb --password x --log-file logfile.txt --extended-log --gpu-off-temperature 90 --disable-cpu --keepalive true --gpu-id 0 --enableduplicategpuid

no instance(s) Availible.
no device to mine with
my gpu is AMD RX570

any advice what is wrong?

When miner starts it is displayed for every gpu like this :



You can see gpu 0 has 2 entries, that means it is running 2 threads, so --gpu-intensity 864+864

A lot of things here is wrong, but basically the main reason is that SRBMiner-Multi doesn't support mining XMR with GPU, only CPU.

Xmrig can gpu mine Randomx. But mining RandomX on your gpu isn't profitable.

Depends which cpu you have.. same as with gpu's. google a little bit around you can find plenty of info  Roll Eyes

V0.6.1

+ Added algorithm 'balloon_zentoshi' (Zentoshi coin) for CPU mining, fee 0.85%
+ 'cryptonight_xhv' kernel small changes, pool side hashrate should be a little higher
+ Auto setup for 'cryptonight_xhv' algorithm is a little more agressive now (if you experience some issues, use --gpu-auto-intensity 1 for lighter settings)
+ Removed parameter '--gpu-worksize'

 @doktor83 Hi i know im risking to seem stupid to a lot o people on the forum but i think its a bit late for me to start programming now that im 35 so i have to ask somebody who knows, now that the 4gb models of graphic cards are more or less obsolete for mining ethereum is there a way to write the dag into the ram of the computer instead of the vram even if its slower or make a hybrid mode like zombie mode other devs implemented to prolong the 4gb gpu cards, the eth asic are using ddr3 memory for dag and achieve good results, is there a  limit in a pc that is crippling it too much to be useful or is it really hard to do coding for such a thing? most of the mining boards use ddr4 which should be a bit faster. Also do you think the enabling of the resizeable bar support in which the cpu can access all the memory on the gpu will help improving hashrate on some algos?
Thank you in advance

But.. may i ask.. why? This is another useless pictures sh@tcoin.

Yes... and why?. This parameter not work in all version, maybe better to make it work?

haven rate to low. trm +5-15%

use standart settings as in example

cards rx 474 574 584 without memory error

possible need additional tune settings? run as admin with tweak enable
