Re: SRBMiner Cryptonight AMD GPU Miner V1.8.8 - native algo switching
For Haven you should try this for Vega56:
Code:
"gpu_conf" :
[
{
"id" : 0,
"intensity" : 56,
"worksize" : 8,
"threads" : 2
}
]
[
{
"id" : 0,
"intensity" : 56,
"worksize" : 8,
"threads" : 2
}
]
No need to change drivers, 18.5.1 is ok.
Also add --preparedata to your start.bat cmd line, it gives a little boost on Haven for Vegas
Thank you so much for the reply and the tips Dok !
I will try it first. looking forward for your brand new SRBMiner Ver. 1.8.9 i have MSI RX580 8GB ARMOR and Gaming X Rigs ready to deploy. Re: SRBMiner Cryptonight AMD GPU Miner V1.8.8 - native algo switching
Not every card can handle the same intensity/tweak profile. So what you need to do is to test separately which tweak profile can you use on which gpu.
For that you need to use the 'gpu_conf' or set gpu's in cmd line.
Thanks for the answer Dok! so, the settings of my OverdriveNtool and even changing my Adrenaline Driver from 18.5.1 to 18.6.1 won't affect anything much to the hashrate right?
can you please tell me the recommended Base Intensity, threads and worksize of "gpu_conf" for Vega56 - CN-Haven algorithm to start tweaking with?
Currently I'm still using basic cn-haven config with "intensity" : 0
thank you !
can i please get the answer Dok? 112 Intensity with tweak profile 3 crashed my Vega56, sometimes even to BSOD. how much should i set my base intensity (for cn-haven algo) before setting the tweaking profile? also, is it mandatory to change the driver from 18.5.1 to 18.6.1 to see the increased performance on Hashrate? sorry for noob questions, thanks

TWEAKING PROFILES [ONLY VEGA56/64/FE/VII]
------------------------------------------------------------------------------------------------------------
If you have VEGA56/64/FE/VII cards i recommend using the 'tweak_profile' parameter because it can significantly (up to 15%) increase your hashrate on every algorithm!
Please read these VERY IMPORTANT things:
1. Miner must run with administrator privileges [right click on SRBMiner-CN.exe->properties->compatibility-> check 'Run this program as an administrator' option-> click OK button
2. Don't apply any memory timings with ElioVP's tool before running miner
3. Don't start testing/tweaking with your highly optimised PPT and ODT settings - because it is probably optimised for a miner/algo combination.. Start with stock settings.
4. Be patient, it takes some time to find settings optimal for your gpu/rig
5. If you start getting invalid shares, that means the profile is too much for that gpu, so lower it
Hello Doktor! I just recently switched to SBR Miner Ver. 1.8.8. Can you please kindly explain more to me about step 2 & 3? I Don't know ElioVP's tool, PPT and is ODT = OverdriveNTool?
I'm Haven miner, and i have three (Windows10 Pro) Rigs with 4x Asus RX Vega56 (Hynix Mem) each. I'm using 18.5.1 Driver, and here is my OverdriveNtool base settings i got trouble with:
GPU:
MHz/mV
P0 : 852 / 800
P1 : 991 / 900
P2 : 1138 / 950
P3 : 1269 / 1000
P4 : 1312 / 1050
P5 : 1474 / 1100
P6 : 1212 / 905
P7 : 1450 / 925
Memory:
MHz/mV
P0 : 167 / 800
P1 : 500 / 800
P2 : 700 / 900
P3 : 940 / 925
Nothing changed in config-haven.txt
with above settings, my base Hash rate is ~1700 H/s for each Vega56. i press "+" up to Tweaking Profile 2, then it is increased to ~1800 H/s for each Vega. but, starting from Tweaking Profile 3, it went to ~2000 H/s then drop to ~1200 H/s in about 10s and not recovering back. (stuck at 1200H/s each Vega)
I've tried Tweaking Profile to 4,5 and 10 and it gave me BSOD with "Video TDR Failure" Error Code.
Here are some numbers from my Vega56 with Hynix memory, just pushed mem up to 940mhs and P7 to 925mV.
Applied only "tweak_profile" : 10 to every config, nothing else changed in config.
Before tweak / After tweak ~ increase in percents
v4: 1854 / 2128 ~ 15%
haven: 1800 / 2000 ~ 11%
Is It possible for all Vega56 to reach 2000H/s per Card with CN-Haven Algorithm? can you please help me / tell me what to do to reach that Hashrate?
I'm sorry if this question is too noob and if it's already answered before. I'm not very good at computer things. but i can follow guide well,hopefully.
Thank you very much for your awesome miner and your contribution to Crypto World!
