21  Alternate cryptocurrencies / Mining (Altcoins) / Re: SRBMiner Cryptonight AMD GPU Miner V1.5.3 on: May 13, 2018, 04:45:34 PM
Interesting, all that gpu-z does (or it should do Cheesy) is to run a few opencl queries, and some monitoring stuff. But who knows.
I tried that suggestion to fire up gpu-z and it should improve hash on 580 8g cards on heavy, but that is not the case here.

Here's an idea for you guys that gpu-z helps: try running --listdevices in a new console window while the miner is running in an other.
So , do a :

SRBMiner-CN.exe --listdevices
This does some opencl queries, maybe some of those that help pumping the hashrate ? Smiley

I will try this next time.

However, unlike istr says, in my environment, keeping gpu-z open is actually good! Turns out it protects from hashrate drop, and unlike him, I do not go through each and every one of them to achieve the full speed, sorry to complicate things a bit, but that's the case with me!



Sorry Doktor,

but your suggestion doesn't work at least for me. It does nothing at all in hashrate improvement as does GPU-Z.
Sorry, but this is the case.

@doktor83   I'm pretty sure that you are aware of all these occasions, I mean with the hashdrop.
Cards with 4gb memory dont have this issue, at least to me. They reach maximum hashspeed immediately.
The problem is with the 8gb cards.
Whenever I start your miner one of them, sometimes more, can go up to maximum, others no and they stay low all the time
even after 2,3,4 hours of mining.
Next time I'm starting your miner some other cards or card do the opposite thing. It's a random situation.
To help things out, you of course the developer of a great miner to me, I found out that running GPU-Z at the time your miner runs
and passing throu all cards one by one and then exiting, voula all cards running full speed. Problem solved.
But of course this is not a solution!!!
Maybe something with the interrupts?
I'm  trying to help!


I wanted to try this, and I got 1000 h/s across the board just by firing up GPU-Z.. Awesome. Wish I had known this earlier! The GPU-Z launch was unusually slow... Very strange! Whatever it is doing to the gpu's, SRB can do too, this gives me hope.

GPU-Z is 2.8.0, and I'm ignoring the update to 2.9.0 in case it works differently, lol.



Hi, could you please explain a bit detail about steps to achieve it? Did you run GPU-Z right before ran SRB? Or while you clicked start SRB Miner, you then ran GPU-Z? Thanks.


Gentlemen,
things are very simple.

You have started SRBminer waiting a while, 2-3 minutes, to report the first hashrate total and give it some time to reach the top hashspeed as doktor83 says.
Then you realize the drop on some or all of your cards.
Now it's the time to fire up GPU-Z as miner runs and uses all the resources of GPUs.
I'm passing throu all GPUs one by one and then exiting from GPU-Z. If you stay running it you'll realize that there's a small drop in hashrate on all cards.
This is normal because of the memory resource usage of the 2 programs.
The great thing is that GPU-Z motivates SRBminer to reach the highest it can get.
As a programmer, I'm suspecting something with the interrupts or the memory management of GPUs.
For some cards it may need to run it a second time or and a third one.
Keep in mind that all this has to do with the RX 480-580 8gb cards which of course I run them with 2 threads and intensity 54, worksize 8.
I reach on them from 1070 to 1148 h/s.

There is no problem at all with RX 570-580 4gb cards. These cards, of course with 1 thread - worksize 8 - intensity 60-61, reach maximum hashing speed at once.
I'm getting on these cards from 755 to 780 h/s.
Sorry, I've forgotten to mention that all these are on heavy algorithm

I'm glad to help the community!
and waiting for a better miner from Doktor83.

@doktor83

Doktore, i need again your help. I had to reinstall Windows 10, i have done all the steps to get it again going. But, when i start SRBminer, Im getting a lot slower hash speed than earlier. Intesity is also different, its 44 now and before was 59. Thats my biggest concern; why intesity has changed.

Everything is the same, cards are the same, Bios is the same, Core and Mem speed are the same, virtually everything.

RIG is 6x 570 4gb.

I was getting 700-720 hs per card with intesity 59. Now 500-550hs with intesity 44. I cannot elevate intesiti more than 44 it crashes.

I'm suspecting that you haven't switch your drivers to compute mode!
Am I right?
