Hi Mate!So because of the invalid shares:
It can happen, but mostly the servers or the pools are the reason. Just have a look at the "Stats". It could also be that the pool is in another region, YOU might have looked? Maybe the wrong port?
It could be the internet connection which might be too slow, it could just be the wrong server or wrong region from the pool as described above.
Your attitudes I believe are the same as mine.
These are my "Start Settings":
setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100
@echo off
cd% ~ dp0
SRBMiner-CN.exe --config config \ config-normalv4.txt --pools pools.txt
AND{ "id" : 0, "intensity" : 124, "worksize" : 16, "threads" : 2, "tweak_profile" : 10},
do you have others?
Topic high performance: (without thinking about power consumption)

OverdriveNTool settings:
P7 1680Mhz / 1000mV - P3 1100Mhz / 923mV
So I did not manage to do more without a crash at the moment. HAHA

Sometimes, I have this error (@doktor83 any idea ?) :
https://drive.google.com/open?id=1E0W1XSJ0ktY61I35wBWLL1KO6FqZ6PdWIt appear when I start to mine with tweak to 10 then I close the miner (or it restart because of GPU crash) then I restart the miner.
Any idea ?
SO I have 2 problems..- One of my GPU can't mine with tweak profil 10 (invalid shares appears.. and not on the others GPU (WHY ??)) This is exacly the same GPU
- If I use tweak profil 10 I have that problem when the miner has restarted :
