Just ordered 20 antminer s5 and two of them are dead when i plug them on

do you think the boards are ok only the controler is fuckd up?

I will test this tomorow morning.

Just tested and... no answer they are still death i had put a good controler from an older command but the same.

In this morning i more had failed.

Yes it would be suggested to have on panels to direct wind.

What I'm seeing is that both my Ebay purchased used S3 and Bitmain purchased S5 work fine.  I have to pay attention to operating temps (changed the S5 fan setup and under-clocked for PS comfort, living space temp and stability).  The S5 is more particular, but it's a good miner!  Interested in the upcoming details of the S7!

had anyone tried to order s5? i cannot select the shippment box.

Ha!!  Don't get your hopes up on the bolded part, I think it'll be a cold day in hell before that happens.

I'm expecting to see the S7 somewhere around 0.4w/gh efficiency.  If they keep the same PCB layout and number of chips I'd figure they'd be hitting around 1.35-1.4TH/s for about the same power draw, basically just upping the efficiency by 20%.  I expect the price to be over $400 when released, just like the S5 was when it was first released.

If they don't beat those numbers by a larger margin, I honestly don't see mass sales.  Anyone with >0.7w/gh and expensive power I could see them pulling the trigger and doing an upgrade, but I really can't see many with S5's feeling the need to immediately upgrade, even those with not great power costs.  Those with free or cheap power it doesn't make much sense to upgrade anything newer than an S4 I would think (unless the price is, as you hoped, halved).

Going by past BM designs, doubtful.

I absolutely agree with the S5 could have been quieter, and that the S3 was perfectly fine for home use. Playing devil's advocate, power density did nearly double in the S5 compared to the S3 which would explain a portion of it.
