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 / 925Memory:
MHz/mV
P0 : 167 / 800
P1 : 500 / 800
P2 : 700 / 900
P3 : 940 / 925Nothing 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!
