No benchmarks are needed. By default prime95 should now be selecting good FFT implementations for Ryzen. Specifically, the 4M FFT should now yield about the same throughput as Intel's 4core chips.

Build 3 is now available.
I'm still seeing cases (this time my Mac) where the program must exit and restart before new benchmark data is used in FFT selection.

1 core / 1 worker timings
I ran a quick benchmark using Build 3 on my Ryzen 1700 and got the following results.
Didn't want the benchmark to take too long, so I selected these settings: Number of CPU cores to benchmark: 1 Number of workers to benchmark: 1 Time to run each benchmark (in seconds): 10 Not sure if it's a bug. The speed of these timings look more like 8 core / 1 worker results rather than 1 core 1 worker. Maybe I'm mistaken, but can you guys have a look too? Code:

I don't know what was going on yesterday with 29.2 B3. Windows 10 smartscreen would not allow it to load. Today, no problems at all. Probably had something to do with a system shutdown and restart.
I'm running a LL doublecheck now. Output is consistent with 29.1 B14.

Another small thing to fix if you have time... This occurs when I'm doing the Torture Test on my 16 thread Ryzen, and mouse over the green icon in the windows system tray. It shows:
SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTest SelfTe i.e. It gets truncated on the 13th one, and threads 14/15/16 don't have a "SelfTest" status text in the the popup. Not sure if it's P95's limitation or there are too many characters for the Windows system tray to handle. If you count the number of characters it's 127... so there's could be a limit due to the way the variable has been initialised as a short string. Last fiddled with by db597 on 20170627 at 12:55
