I'm going to chime in and say that after only recently ordering an S5 from them, I have to say their support has been great.
Expected delivery is also only a few days after I sent payment, which I can track.
Also, I noticed some user(s) reporting that the recent S5's have additional heatsinks on them.

Getting half hash speed and one board full of dashes Miner suddenly went into this mode and it's always the same board. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FtuA5XBV.png&t=665&c=nmCtdJO9SLQ4cg) I tried running it in one board mode and the other board works well. Sometimes when running in two boards, the hash rate will drop to 0 Tried reflashing firmware, hard reset and also reflashing with Keep Settings unticked. Double checked all wirings. Tried changing PSU also.

Yeap i double checked the connections and switched cables around Using a Delta 2000W thingy. I took it out and also saw the wet pastes and even reapplied it as well. Looks like the board is truly dead?

Looks like the board is truly dead? I would check the PSU as final thing i you have another S5 to make sure psu is working (you might have done this already). If you have done that it's not looking good for the board, sounds like it's likely having a problem. You can start a ticket over here to talk to Bitmain Support about the troubled board. Tell them all you have done to troubleshoot in ticket, I'm guessing it is likely needing replaced. - https://bitmain.zendesk.com/hc/en-us .

i think the price increase may be because they added heatsinks to the other side of the hashboard on the newer S5's. if you look in this thread: https://bitcointalk.org/index.php?topic=1072176.0;allVorta states that one of his came with the heatsinks already on it. that is where this image came from. i am curious if this actually came from bitmain. if it did; that would explain the price increase. To do so I've: - Repasted the miner with a much better termal paste,
- Added mini heatsinks on the external side of the hashboards with adhesive termal paste (to the first miner only, as second came with them),
- Closed the miner's heatsink with 3D printed plates so no air can run out on the top or bottom sides,
- Added fan ducts between fans and miners which direct most of the air through the main heatsink and blow just a little bit of air to external heatsinks, just to drive some airflow on the sides.
Im going to email bitmain an see if they come with the heatsinks now.

Tried changing PSU also. On the top of the control board there are 2 spots on both sides for the hashing boards might want to move that one over by one and see if it works. If its out of warranty.

The second one looks like an unhappy board (try on different PSU, then swap its port on a controller to see if we can coax life into it) but the first one looks like an unhappy controller/PSU. That is evidence by BOTH boards being unstable (very unlikely naturally) and that the fan is going at 3k without any temp indication. You can try connecting the hashing boards on another controller if you lay 2x S5s on their sides and get the cables to reach.

I will test this tomorow morning.

Hello sir, there was short batch or miners with heatsinks on a side.
not sure if factory will continue with that option.
best regards, Bitmain_Z

I saw the images you sent to support. What PSUs are you using, and can you try a more stable pool than betarigs.com please?

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!

with what im seeing in the gekkoscience bm1384 thread the s5 could have been made almost twice as efficient, had they have tried harder...
perhaps they are doing that.
if they dont release a miner that is more efficient and half the cost.. its not going to be worth buying.

I know they are not currently shipping because of the Dragon Boat Festival but I don't know if that has anything to do with the functionality of the site. "Generally, shipping out within 48 hours after full payment. We'll have Dragon Boat Festival from June 20~22, the last shipping date before holiday will be June 19 and resume on June 23rd after we come back."

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).
