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..

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°

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.

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 ?
