Re: SRBMiner Cryptonight AMD GPU Miner V1.7.1 - native algo switching
V1.7.1
- Added new algo FreeHaven
- Small OpenCL optimisations
- Added 3 different modes for heavy algos (Heavy, Haven, BitTube, Italo, FreeHaven)
- Added value '9999' for fragments, that sets internally to the value it was in previous 1.6.8 version
- Fixed benchmarking mode + startup monitor bug
- Fragments, aes, bralock and heavy_mode can be set now outside gpu_conf, so it applies to every GPU
- Freehaven algo is here, a lot of you were waiting for this
- Added new parameter "heavy_mode", it can be used in gpu_conf, or just in the config, it is applied if not in auto mode (intensity = 0).
It can be 1,2,3.
1: This is the default method for doing heavy calculations now, it's more stable and should produce less compute errors than in the previous 1.7.0 version. Note that worksize 9 isn't the optimal worksize anymore for Vegas if using this mode. Worksize 8 now gives better results, you just need to find a good value for intensity.
2: This is the calculation method from the previous 1.7.0 version, use it if you can get better results with it than with mode 1. Note for Vegas : worksize 9 is optimal here.
3: Experimental mode, it is the fastest but tends to produce the most compute errors, if your GPU's are tuned maximally to the edge. I put it here because maybe someone can get the best results with it.
- Ellesmere 8gb cards just love to throttle hashrate on heavy algos, lot of you said you had better results on previous versions, so if you set fragments to 9999 it uses the same internal settings for it used in 1.6.8.
I am sure with the new mode for heavy calculations higher hashrates can be achieved, but a lot of users just copy over the old settings and guess what, does are not optimal anymore.
With the new method you should lower the intensity a little bit than before, and find the right fragments setting for your GPU's. Some users reported they have higher hashrates after playing a little bit with these settings.
- I had to add parameters 'fragments', 'aes', 'bralock, and now 'heavy_mode' to the config file outside the 'gpu_conf' because.. well, nobody reads the first page or readme.txt anymore
