Received new firmware from Bitmain- thank you. But to test it you need to put your miner into jeopardy and I'm not willing to burn up one of my miners right now. If Bitmain wants to ship me a beat up, old, dusty, used miner to test with I'd be more then happy to test it out completely in a home situation.

They did always have good support, got busy at times but always helped out when they could. They had some growing pains, but all companies that grow so fast do.

The fan control firmware? i have tested already same problems you can set your fan speed manually but it dosent work, the miner stops mining when hits 80C that works.

If you try to OC your miner it wont work because is not saving the OC option and your miner will work default at 200 MHz tested this firmware on 30 s5- and now i-am back to the 01.IAn firmware.

Just recived my s5-s from warranty and one board still not working.

Wtf, why are you sending the bad boards back?

Where are you located? Which version of hash board you received?

Located in romania, last week i had shippment some boards to warranty to bitmain, they fix the boards and shipt them back but surprize... one board still not working.

why do they send bad boards? with the QC passed sticked on the board i had payed the DHL shippment to china very expensive.

Guys, do you use 2 fans in push-pull on your S5s or just one fan? IMHO 2 fans provide more "comfortable" environment for all chips amongst the hashing board, especially for those located closer to the "pull" fan, even if temperature sensor located in the middle of hashing board does not allow you to see huge temperature difference comparing to 1 fan configuration.

What do you think about it? Does second fan give any benefits or not?

p.s. I am sure it does, I just want to hear your thoughts about it.

Another question. If you order, are they still shipping used/dirty hardware or are they new? Anyone receive an S5 lately?

Received 5 yesterday... only one had mild dust on the fins... One fan cable was a little bit burnt, weird.

"Brand New" units, folks ! ( https://bitcointalksearch.org/topic/m.10713712 )

In all seriousness, Bitmain, please make an effort to stop lying to your customers in the future.

So what would cause this:

About 6 hours ago I got an alert because the speed dropped on one of my S5s, it dropped to around 850gh/sec, when I logged in and checked two asics are just gone.

I haven't been able to physically inspect the box yet, but its sitting in a controlled datacenter, power draw was normal until it suddenly dropped about 10%

Instead of remote reboot. I would give it a PSU turn off, then back on. I suspect there is a good chance it will go back up to spec.

From picture it is still hashing on both boards since speed. And there are no X's showing dead chip so also good.

Let me know of the full power reboot on psu works.

I just ordered two a few weeks ago - they arrived and good condition and working order... There was a bit of dust in them, but nothing compared to some of the other used units I've bought, so I think it's safe to assume they were in use but not abused in any way. One bummer thing is I was hoping to get some with heat sinks on them, but alas the two I got did not have them - but I found some on eBay that did, so I bought those to check out.

They did ship very quickly, I think I got them in maybe a week and a half... I actually just bought a replacement Beaglebone for one unit that was having issues (another one I bought a while back used), and it arrived in a couple days from China, pretty impressive.

Somebody here posted a graph of S5 overclock settings and profitability. It showed the optimum frequency to overclock. Now I come back and can't find it. That is what I get for reading this board in the middle of the night and not noting something interesting.

If anyone can provide a link to that graph, I would appreciate it.

I suspect you might have been thinking of this one - it's another thread, not about the S5, but the post was

Yes, that was it. At a glance it looks like 425 MHZ is the way to go. At least that is working for me!

Thanks,

Hello! Recently I bought 17 pcs. of Antminer S5 from Russian reseller Igorgan1983 . A couple of days ago when the Internet access lost during the night, the temperature at hashing boards on 4 of miners was about 100-125 degrees, the fans was spinning at some minimum speed, so these 4 S5s has been burnt. After rebooting, the status of it's chips was -------. Now I sent all 4 units to reseller and he sent them to China. For shipping these miners back to China I will have to pay around 7000-8000 roubles.

Thereby, I have following questions:

1. Is it possible to compensate the shipping cost of transfer S5s to China?
2. Is it possible to accelerate the process of consideration of my case (there has been passed almost a week since the blades has arrived to China)?
3. Among the 17 S5s one has arrived to me in a used condition (blades version 1.7), I have already sent a pictures of it to you before - can it be replaced with completely new one?
4. When will be issued a firmware that fixes a bug with S5s overheating during the absence of the Internet access?

Known bug first reported by me in March 2015. I almost burnt up all my miners twice because of this. Then put my fans on direct. Any miners burnt up because of this bug should be replaced for free. Yoshi has helped me in the past, is he still around?

https://bitcointalksearch.org/topic/m.10833820

i 100% agree.. i shut mine off before it burned up. but if i wasnt home who knows.. it was really hot.
and also who knows what long term damage it did..
