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

[doktor83]

Hi guys !

I'm really lost with those config.. My rig isn't stable. I got all the time crash, or bug and I don't know why.

I'm using Windows 10 1809 with 18.6.1 drivers and  I got 3 Sapphire RX Vegas 64 Nitro+ and 1 Sapphire Radeon HD 7950

I'm using SRB Miner 1.8.6 with my 3 Vegas and i'm using XMR Stak with my Radeon HD 7950.

This is my config in SRB Miner :

{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
   { "id" : 1, "intensity" : 122, "worksize" : 16, "threads" : 2, "tweak_profile" : 0},
   { "id" : 2, "intensity" : 122, "worksize" : 16, "threads" : 2, "tweak_profile" : 0},
   { "id" : 3, "intensity" : 122, "worksize" : 16, "threads" : 2, "tweak_profile" : 0}
]
}

-----------------------------------------------------------------------------------------------------

SRBMiner-CN.exe --config Config\config-normalv4.txt --pools pools.txt --logfile %LOGTIME%

----------------------------------------------------------------------------------------------------

Sometimes I got GPU crash then SRB try to shutdown my PC and it freezes.

This is my Wattman config :

GPU Clock : -8%
Memory Clock : 1105 Mhz

My Hashrate with tweak profil to 3 :

GPU0: 2149 H/s [T:68c][BUS:10]
GPU1: 2155 H/s [T:68c][BUS:7]
GPU2: 2157 H/s [T:67c][BUS:3]
hashrate: Total: 6461 H/s

That is really low with Vegas 64 Nitro+.. Doktor83, with your 56 you have 2100 Hashrate with each cards with tweak profil 5.. (In your video)

----------------------------------------------------------------------------------------------------

Something to change ?

Doktor83 I have try to use "min_rig_speed" option but there is a bug with this one in SRB 1.8.6. This is not the good average Hashrate. If someone can try and confirm that is a bug..

I don't know why you have crashes, but your vega temperatures are too high (thats +10c on the vram).

1.8.6 has 10 tweak profiles, so you have 7 more to try

Also you can disable the watchdog so it wont restart the miner on gpu crash, use --disablegpuwatchdog.

I would first try to lower memory clock, get temps down to at least 60c.

min_rig_speed gets the average hashrate for 'min_rig_speed_duration' time, that is 5 minutes if not set by the user.
So please describe what you think is a bug.

reduce Memory Clock : 1105 Mhz
to 1090mhz and try - 1100 is normal - 1107 is very high(my vega64LE not work normal woith 1102mhz)

My memory clock is now : 1100, I will try it and I'm using "target_temperature" : and I fix it to 55°

What is the default value for RFC on the samsung V56 ?

vega56 reference with samsung, stock timings according to Eliovp utility

Hi, Dok!
Just examined your timings for profile 10.
They are good for hynix HBM2 but for samsung (both low voltage 800-940 mhz vega56 and high voltage 945-1100 mhz vega64 I have much better (more stable and fast) mem timings)
I can share to you if you want ))

Ok, so now i have examined your V64 samsung timings and i can't see why they would be much better, as you say.

Can you run profile 10 on V64 with samsung mem?
If you can, what's the hashrate with profile 10 vs your timing on the same algo?

my timings are stable up to 1090mhz hbm clock. Yours feel fine with 1107 but I didn't test for long.
Mine are 2350h/s cn-r (teamred) vs yours 2200h/s (teamred) with 1090mhz clock. Claymore's is 49.5 vs 48 mhs eth.
With higher mem clock (1107mhz) with your timings results are getting better but didn't catch mine at 1090mhz.

[ZaGunShow]

Any reason off the top of your head why the tweak profile would be completely unresponsive? It mines the same without it and does not add a line (like in your video) "Applied Tweak Profile 5...." etc

Nope, thats not normal, can you try to set 'min_rig_speed_duration' to for example 1800, that is 30 minutes. Im curious if the same thing will happen.

my timings are stable up to 1090mhz hbm clock. Yours feel fine with 1107 but I didn't test for long.

Thanks for the stock values.

That is a huge difference in CN/R and it shouldn't be, im wondering what settings did you get for 'my' timings. Can you share them ?

My first guess would be that you are not running the miner with admin privileges. But you can see in the log what is exactly the problem.

here what I see on vega64lc with srbminer 1.8.6 and profile 10
I used timing = 0 (auto) option from drivers with srbminer.
When I applied custom timings shown above I used timing = 1 driver mode.
Don't know if it makes any difference

Should I change something to get better hashrate ?

Probably not. Thanks for helping.

Ok, i will check it out

edit:

this is happening only on CN/R because of kernel precompilation. It messes up the average speed. I will think of a way to work this out.

With v4 i am getting same values with intensity in 75 or even 110. My best rx 580 8gb with micron at 1150/2200mhz custom timmings is doing 955 h/s, guess its super hard to pass the 1000h/s without pushing core clock?

Just because TRM not supporting them. Wownero is CN/R and with SRB i have 11.5kH with 12 GPU rx 570 8GB Micron 1320W electricity consumption,TRM is same hashrate and settings but 1260W EC. But 2.5% of dev fee is eating those 60W. So,about the same
