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.

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?

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

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.

why even post troll

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

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).

[tvukoman]

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...

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:

From first page then open table to see best results:

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

Anyone with AMD R9 380 cards?

I was getting 600hash with v7 now 485hash only.
Any better results?

[Marvell2]

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

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

cooling is not the problem, neither is power , these rigs wer mining eth , which uses lots more power

[Bojcha]

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.

I'll give you something better but for worksize 16 / intensity 58. Not compiled with any recomended driver.

Hi Guys, I'm new here and new with SRBMiner too. I need some suggestions on how to improve my hash rate. Currently my 7 Vega rig only managed to reach about 1850 H/s per GPU with total power draw of 1550 Watt at the wall. My GPU is Gigabyte Vega 56 OC with stock BIOS. However, I've applied Soft Power Play Tables into it and currently using driver version 18.6.1. My OverdriveNTool and Config settings as the following:

Code:

GPU_P0=852;900;0
GPU_P1=991;900;0
GPU_P2=1084;900;0
GPU_P3=1138;900;0
GPU_P4=1150;900;0
GPU_P5=1202;900;0
GPU_P6=1212;905
GPU_P7=1408;905
Mem_P0=167;900;0
Mem_P1=500;900;0
Mem_P2=800;900;0
Mem_P3=960;900
Fan_Min=3700
Fan_Max=4900
Fan_Target=75
Fan_Acoustic=2400
Power_Temp=75
Power_Target=0

Code:

{
"cryptonight_type" : "normalv8",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
{ "id" : 0, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 1, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 2, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 3, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 4, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 5, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
{ "id" : 6, "intensity" : 112, "worksize" : 16, "threads" : 2, "persistent_memory" : false},
]
}

I'm looking forward to reach 1900 H/s OR same hash rate (1850 H/s) with lower power consumption. Thanks in advance guys!

pfft

the moment I apply the soft power play tables i've been using since last year, 1 or mroe of the gpus goes error 43

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.

I'll give you something better but for worksize 16 / intensity 58. Not compiled with any recomended driver.

Thanks! I'll try it! But can you make same file with 8 worksize?

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



you did no bios mod?

[playfast]

Made another discovery with my rx560 rig, v8 actually prefers lower intensity than v7.
0.5 less manual intensity gave all my cards another 15-25 h/s.

[dragonmike]

I'm just struggling with the Vegas.
Doesn't seem to matter whether I increase voltage or lower clocks, after a few minutes mining Monerov8, all GPUs go boom, i.e. SRBminer says hashrate is zero for every single card... and it will fail automatic re-initialisation.

Using 120/16/2. They're all 56's flashed to 64.
Maybe I'm just at the limit of what the PSU is able to cope with... Power draw is between 1400 and 1435 for a EVGA 1500 G2...
