  1. Ended up getting it sorted out myself - I remembered reading somwehere that the 16-core Opterons were actually a 16-core chip with 8 FPUs (2 cores share an FPU). I decided to try forcing the cores slot to 8 (instead of -1 / auto), client is using 8 CPUs now and ppd went from ~520 to ~240k ppd. All I can guess is that having 16 threads competing for 8 FPUs was causing too much contention for a FPU slot and jamming up thread handling. System shows ~50% CPU load now which is fine if it turns out more ppd. If I go up any higher on the CPUs, ppd actually drops. To test the theory, I went up to 10 C
  2. Doesn't really answer the question though as why it went from a much higher ppd down to 500 ppd or why a single thread on a haswell i7 is now 8x faster. And if your Ryzen is at 100k ppd, that is 200x faster. Your CPU isn't 200x faster in any benchmark . Something is still amiss...
  3. So I'm folding on some extra hardware I have laying around and one of the systems is an Opteron 6276 (16 cores, 2.3GHz). Since it's winter, any heat this thing generates while folding is fine (house is electric heat anyhow, same cost per kWh lol) Server chassis, completely adequate cooling. Folding@home CPU slot set to -1 (client determines cores), client sets CPU:16, task manager shows totally maxed out (100% across all 16 logical processors) and I'm screaming along at.....527 ppd? For reference, our HTPC is set to use only 1 core, no GPU, and it's doing ~4500 ppd. Office PC is doing nearly 1
