ElGabo....
By warmer temps, we mean around 60-65, not going from 20 to 30.
Did you go that high?
All mine love 60-70, way better than 35-45. the hw error rate dropped drastically.
We have confirmation they are rated to go all the way to 105, so thats well within norms...
as well as the temp of 28nm asics known to run better as in the article posted earlier...
I'm sure you will see the difference if you tried 60 rather than 30 or 40.
just sayin'.
Now mine runs 551 rock solid between 30-42C with HW rate 3,4%. (if something not broken....)
I've tried up to 55C, no more but it was worse.
What was your HW rate before the drop? I don't know what is the best way... I figured out something what is runing rock solid with good numbers and keep hashing away or loose time and keep playin'...??
I got my miner on the 8th, yesterday was the day when I said ok, I wont play mor it's fine... I played with every day to figure out the best options. (for me it's much more about playing. I'm ok if i got my money back and wont earn a cent more... its my fault i know)
But an other interesting...
I wrote it when I got my miner but it was a lot of pages ago, so I write it here again.
When I got my miner, spent 2 nights to figure out wich pci slot works best with witch card. I don't know it was a firmware issue or something else, but if somebody has a mercury or something, maybe should try to change the slot and let it run for a while. I had musch difference in speed.
