Probably not. Thanks for helping. 

I'm gonna try !


Should I change something to get better hashrate ?

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

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.

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 ?

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.

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
Rig of vega 64's

{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"tweak_profile" : 5,
"double_threads" : true,
}

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.

vega56 reference with samsung, stock timings according to Eliovp utility

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


When I use min_rig_speed option with 6000 H/s with this config the option says : Your average Hashrate is lower then 6000 (2100 H/s sometime 4200 H/s) but in SRB my average hashrate is 6400 H/s. That's normal ?

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)

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..

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?

Thanks but i still miss the V56 Samsung default RFC )
Not V56 flashed to V64, because that uses the V64 timings.

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

Ok, this is for Vega 64 LC

You can share to help the folks here, im not using predefined straps in SRB. They are calculated based on existing settings.

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 ))
