I see a lot of people using 376.09 drivers.
Is there a specific reason not to use latest drivers? I'm mining just fine with 376.33.
No, but there isn't reason to update your drivers either.
376.33 drivers don't increase your hashrate.
Well with the newest pascal cards, you can always hope something will improve, but usually it'll do nothing if your previous version isn't that far from current. I recommend doing testing, and for easyness to change between version use restore point in windows, very useful
Updating my bios's was a huge PITA all for about 8% more hashrate. When you have mixed manufacturers on one PC a lot of the update utilities don't respect models and will flash their bios over other manufacturers cards. That was a lot of fun digging up bios's to flash them back after that. Other manufacturers wont flash multiple cards (Asus update). It was a grab bag.
Best method is using nvflash and updating one of the cards with the manufacturers package, saving the updated bios with Nvflash, and then flashing all the cards at once by unplugging other models from the system.
In other news apparently you can't get that last couple % out of cards by running multiple instances anymore. EWBF still only uses 97-98% of my GPUs where as Nicehash uses 99-100%.
Worth noting, when running on Maxwell (970s) hashrate is 10% slower then Nicehash's miner. That's a pretty big difference. If you're running multiple Maxwell rigs it's better to stick with EQM.
Also .8 is still quite unstable. Multiple machines were completely stable with EQM, I have to reduce the memory clock a extra 100mhz to be stable in .8.
Latest version 0.0.8b with 3 process has an average GPU usage of 99% for me. (1 bat file per 2 cards on 6 cards rigs).
Stability wise, running with no rejected shares for the last 4 hours @ average 374sols/s per card. I use the same OC i was using with EQM, so far so good
Agree with you, bios updating for heterogeneous rigs is horrible...

Would love to see threading support from EWBF, as well as loggin and monitoring features for sure
