Just in case anybody's interested I had a play with TDP reduction to see what the best performance would be with reduce power usage, heat, wear and tear etc... on my 1070.
At stock I get around 367 Sols/s with the new release. Reducing the TDP gives the following:
| TDP Dec. | Sols/s |
| 0% | 367 |
| 10% | 363 |
| 20% | 355 |
| 25% | 350 |
| 30% | 343 |
| 40% | 317 |
I've gone with a 25% reduction in power usage which only reduces Sols/s by ~5%.
Thanks. You should also try to overclock the memory and core and combine with reduced tdp.
