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

[dingdongtobias]

Miner is very unstable on polaris cards , constant crashes and reboots on most of my rigs

no problem on 470, 570, 580 cards if you set good. you don't know to set good, sorry.

[Marvell2]

more juice and lower intensity, which cards?

mix of 470s 480s and 570s , all my cards are set really low core like 1130 mac or 1080 with the voltage around 900 works great on eth and had no issues on v7 using claymore.

mem is set from 1800 to 1925 max

with srb having lots of rigs randomly go down using the default picked intesities.  tried a fixed intensity of 50 and do I have to go even lower?

v8 is significantly more power hungry, check your power supply and cooling

no trolling, written 100x times v7 settings not good for v8, you must find good settings, and v8 need more power.
v8 not v7 and not eth.

why hard to read previous posts

I think I saw messages here about the successful launch of srb on v8 on pitcairn, but I could not find it. Install recommended driver first and then try to use the settings that are in this message for tahiti.

Radeon R9 270X 4Gb (Pitcairn) with manual modded bios, Windows 10 x64 Pro, 18.10.1 driver. Gives 500 h/s on v8 with kernel 1, with kernel 2 speed slower.

Owners of 580 8Gb please share your settings and wich kernel file you're use?

[kostepanych2]

Can someone help me to create a batch for set gpu and mem voltages?

+ "startup_script" can be used to run a script (batch file) before miner starts. You can for example set clocks, voltages, etc. specific to that algo

I'm also interested in how to set GPU and memory clocks and voltages with SRBMiner...
Is it possible? Can't find any examples...

[Lunga Chung]

This is my setting:

RX580 Sapphire Nitro + (Samsung) 4gb

{
"cryptonight_type" : "normalv8",
"intensity" : 59,
"worksize" : 8,
"double_threads" : true
}

Wrosksize can 8 or 16 doesn't change much.

Best card 989 H/s, worst card 973 H/s

OC:

Core 1260
Voltage 900mV

Mem 2120
Voltage 900mV

I realised my config file is missing a comma and causing errors in the miner.

Did anyone notice a very annoying bug with AMD drivers since 18.2.1?

SRBminer doesn't properly identify cards anymore. On one rig, every card is a RX480, not a problem, since all of them are ellesmere (480, 580, 570).

However on another rig I have with a RX 570 and a RX 560, both are detected as RX560 and the ellesmere card gets an intensity of 29 with dismal performance...



With 18.2.1 drivers all works as expected



Thoughts?

[ntshb]

Soft power play tables?

Every time i used it, some of the gpus will have error 43 no matter what. 18.5.2.

No, voltage is set on custom bios.

Please, how you use this parametr "kernel" or  --cgpukernel 1? And where? Type you config, please...

I use config.txt file. Here on 270X:
"gpu_conf" :
[
        { "id" : 2, "intensity" : 36, "worksize" : 16, "threads" : 2, "kernel" : 1},
]


P.S. I need file g2_CNV8_w8_k1.srb from cache folder. Who can share it compiled with 18.6.1 driver?

I think found the best method to calculate intensity and threads for GPU's to mine cryptonight_v8. Almost is working for me with 3 different GPU's.

First found total "compute units" or "ROPS" of GPU to use.

Example 28 compute units. 2Gb GPU Ram

Then rest 2 for internal work of GPU and OS needs. 28 - 2 = 26.

If use total compute units GPU don't have sufficient memory to work.

26 Compute units. Then multiply * 2. 26*2= 52 is the intensity for a GPU with 2Gb ram and 28 compute units and using 1 thread. With this configuration GPU works with maximum ram that can do. ~1700 Mb.

If we want to use 2 threads don't multiply * 2. Every thread is ~850Mb of memory used. Intensity 26 and  threads 2

If the GPU have 4Gb we can use intensity = 52 = 2Gb and threads 2 = 2Gb (total 4Gb ram) or intensity=26*4= 104 and 1 thread.

Worksize is minimun 8 and works fine in multiples of 8. 8/16/32.......the greater worksize is, greater time to found a result.

With a 1Gb GPU is easy. 28 - 2 = 26 intensity and threads 1 ~850Mb memory used, or 26/2=13 intensity ~425Mb memory used and threads 2 = 425Mb*2 = 850Mb memory used.

I hope this can be useful for some cases.

I use this variable in batch file: setx GPU_FORCE_64BIT_PTR 0

Plz help!
Hello all!
I have error, whats wrong?
Test on Adrenalin 18.6.1 and 18.8.1

Not completely true. One has to separate clocks and settings to be perfectly clear.
I'm able to run pretty much the same clocks on my Polaris cards in v8 and v7.
The initialisation parameters do change however. I use 57/16/2 on v8 and 59/8/2 on v8 (that's on 4GB RX 570's).

First in start.bat ad this: --startupscript Run_OverdriveNTool.bat
In Run_OverdriveNTool.bat you must set path in OverdriveNtool.ini with proper setting for your card and specific algo. Example: OverdriveNTool.exe -r1 -r2 -r3 -r4 -p1Sapphire_BT -p2Nitro_RX570_BT -p3Asus_Vega64_BT -p4Gigabyte_BT  <-- on that way i set up miner for mining BitTube algo.
Now set up OverdriveNtool.ini for specific card and algo (same name from OverdriveNtool.bat)


Core and memory clocks are set with OverdriveNTool:

Please, who have rx 580 card and 18.6.1 driver, launch SRB with worksize 8 and share with me file g2_CNV8_w8_k1.srb from cache folder inside miner folder.

The same problem for me. I solve it deleting files in cache folder of srbminer, restarting pc and start miner to compile kernels again.
