I made numerous experimentations with the High flag and various values for the chunkNonce of Jminer and the cache size of Blago miner.
No major change occured what so ever…
The outcome is that there is a small increase in the performance of both mining program when I REDUCE the chunkNonceSize and the cache size respectively!
I used values around 6000 to achieve a decrease in the reading speed of about 1,5 sec(from 10 to 8,6).
I thought that it would be the other way around!
But I get the feeling that none of my GPUs are been used to the full. I have the CPU-integrated Intel HD and a dedicated AMD M440 4GB. Both of them, after an initial reading burst in the first round, they tend to be even slower than the CPU after the second round.Of course I have installed all the latest drivers.
