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

[Lunga Chung]

Hello,
I have RX580 nitro+ 8 Go ( Micron memory and samsung ) , I'm running at 1150 core 2250 memory , stable but at 850h/s. What king of bios are u using ?

You can use SRB PBE pimp my straps

Cool!
With new version my RX 580 4GB give me about 10 H/s more & my 580 8GB about 15 more than with previous version.
Not tested fragments & bralock yet, so maybe it can improve a bit more.

Ups! My first test gave me +10 H/s with 4 gb card but now is very unstable reaching up to -90 H/s than before, tested changing intensity but no change.
The 8 gb is running fine.

Is it mandatory to use Adrenalin 18.6.1 or 5.1 as stated on the start page? I upgraded all my miners are 18.10.1 when it was released, and the thing works without any issues (vega 56 and 64). Are there some advantages in hashrate or power consumption on 6.1 or 5.1? I go to test 18.10.2 now 

[vmozara]

I have Vega 64 watercooled PC running 100% table and 1550 core and 1150 HBM2 - After installing newest driver my hashrate dropped by 15-20, from 2130 to 2115 but had a massive drop in power consumption. I am now remotely installing 18.10.2 driver on one vega rig to see the result. Maybe AMD blessed us all with new driver, maybe I did something wrong, wait until installation is finished, I am very excited now  

I screwed up, sorry guys. 7x vega 56 rig dropped about 100H/s with new driver, without change in consumption.

Played with "fragments" setting, the default from compiled kernel was 4. Found 16 gives best hashrate for my rx560 2gb cards. Tiny ~4 H/s gain.
Will try to squeeze something from bralock soon, might take hours of testing

Hi everybody,
How to fix compute errors?
Thanks

Lower overclocking, rise voltage if undervolted. Use native bios.

Sorry, you are right.

Here are my tests after 40-50 tries:

Drivers: Modified blockchain drivers for W7, not using precompiled kernels from 1.6.9
Algo: V8
Config at this time:
"gpu_conf" :
[
   { "id" : 0, "intensity" : 100, "worksize" : 8, "threads" : 2, "fragments" : 16, "bralock" : 50}, RX 580 8gb, connected to screen
   { "id" : 1, "intensity" : 61, "worksize" : 8, "threads" : 2, "fragments" : 16}, RX 580 4gb, with riser

V 1.6.8

Same actual, above config, without the fragments and bralocks
8gb card, very unstable, giving an average of about 935 H/s
4gb card, very stable, giving 1002-1005 H/s

V 1.6.9

8gb card, after playing with fragments & bralock I get 975 quite stable, with some peaks and valleys, this is about +40 H/s from 1.6.8

4gb card, here are the problems:
Rarely, I start program & have 1012-1015 H/s it is +10 H/s
Other times it start at about 950 H/s (+- 10 or 20 H/s, sometimes up to -40 H/s), after 2 to 6-8 minutes at some point the hash rate increases reaching above 1010 & stays there for the time I tested
Often, it starts about 950, like explained above but never goes higher than 960-965 H/s
I tested intensities from 50 to 62 & the same happens, also played with fragments, memory speed & bralock but no changes

Thank you.

Hi guys. Use srb 1_6_9 on my 7970 and have a less hashrate compared to 1_6_8. The problem is that the value of "fragments"  does not change, it is always 4. Heres my config.txt:
{
"cryptonight_type" : "normalv8",
"intensity" : 57,
"worksize" : 16,
"double_threads" : false,
"fragments" : 8
}


Where is my mistake? Thank you.

What is your hash rate for the 7970? What is the clock speed?

You can't define fragments there.
Do it like this :

Code:

"gpu_conf" :
[
{ "id" : 0, "intensity" : 57, "worksize" : 16, "threads" : 2, "fragments" : 8}
]

Last stable results on v8 was 470-475 H/s. Driver 18.6.1, win 7 x64, srbminer_1_6_8 intencity 57, worksize 16, no doublethreads. Clocks 1100 core / 1500 memory.

Thank you, now it works. As i understand value of fragments can be equal only to this values:0,1,2,4,8,16,32,64,128 ?

Yes, that's right.

You said you have less hashrate with 169 compared to 168. Is that what the exact same settings?
What numbers were you getting on 168, and now on 169 ?

Doktor, kudos on your fabulous miner and keep up the great work!
Question, is there a way to see which particular GPU found results/shares?

[nordmann666]

is there a more detailed log level possible?

miner stops mining until i see that there is no action since many minutes...have to press key and than i got error messages with many invalid shares following

if win10 don't click in the miner window that halt miner execution, you have that problem 100%

it stopps without clicking in the cmd - and i disabled quick edit mode

With Srb_1_6_9 with same settings and drivers (only new version of miner) i got 465 H/s. The only i change the value of fragments. 1,2 shows very low hashrates 150-250, and the best for my card is "fragments" :16.
