Bitmain can we have S1->S5 upgrade kits ?

as i posted before, most important is whether it still uses the same power as before the internet failure-could be easily checked with a kill-a-watt. If it does, then it would be very dangerous. If not, than it is just residual heat (as chips are NOT working anymore) and maybe metal sinks will dissipate the remaining heat safely, even if they heat up to 90C intermittently. Using my S5, as soon as internet drops, power usage also drops to very low (maybe 20w). Whether some other individual miners don't do the same (drop in power usage) is essential to know. i agree that they should have program it to rotate fans for a couple of minutes after the internet blackout.

I can confirm in my case (by a kill-a-watt) that power consumption does drop way off.  But the heat is really up there (to the touch and immediate ambient).

Thank you.

Remember, they weren't mining or even connected to the pool at this point. The temps just started rising past 80c without shutting down. The firmware seems not to shut the rig down when it is over 80c. That really needs to be fixed.

Well that goes against everything I've tested, pulled the ethernet and nothing exciting happens. And I've previously tested the 80C limit, it 'freezes' and stops mining.

I agree - it doesn't make sense.  My S3's properly honored that 80C safety shutoff.  But on my pair of S5's, it does not shutoff over 80C.  BTW, the miners really do heat up and it's not just an errant report from the firmware.

A few weeks ago when Ghash went down, my Nicehash limit for return value wasn't met and so it stopped hashing (no rollover) and I did catch this screenshot.

This is exactly what happened with mine. The connection to my pool didn't drop out %100, but was still hashing at like 400Gh/sec. I knew something was wrong when I heard my fan slow down considerably. Soon as I checked the web interface and saw the 92c I kind of freaked and just powered them off. So regardless of what everyone says we shouldn't even be seeing a temp over 80c on our screen if the shutdown/freeze/stop is working properly, correct? I would have grabbed a screen shot but I didn't want to burn anything up. It confuses the hack out of me. Not hashing, but the temps kept rising and I physically felt the heat from the miner before powering off.

Dogie, I know you want to keep dismissing that this could be a bug in the firmware so would you go on a deal with me here? I'll pull my fan connector off while it is hashing to see if the miner stops operating and protects itself when it hits 80c. I'll perform this if you promise me a new S5 if I burn my rig up?

I'm not dismissing anything, I'm hypothesising while BW has units in hand and is testing. My unit needs a fresh controller otherwise I'd test mine to destruction.

Whatever you do to your own unit you do at your own risk.

Oh, I thought you were "in" with Bitmain and could get another S5 fairly quickly if yours blew up while testing for the team? Fresh controller? Your controller died or something?

Thank you. Message received. I also found another screen shot of an S5 with temps over 90c+ from Rabinvotch. His unit didn't stop hashing or shut down either when it hit 80c. He has a screen shot in his own thread, and I'll grab it from there and put it here also.

This picture is from this thread:

Temps should of not reached that high. Machine should of stopped hashing or "freeze" like Dogie said. How could it still be hashing at temps in the 90's when there is an 80c shut off?

[opentoe]

Well, I pulled the fan connector off and let it go. Temps quickly raised to 65, 70, 75, 80 and since I had M's monitor program running that even popped up a warning that my temps were over 80c. So I took a quick screen shot and immediately powered down. What's weird is the 5s hashing went away and the average just kept going, which was pumping the temps up. I had an iR gun pointed into the fins and I couldn't get an exact reading, but at one time it came back with 194F, which is 90c. I didn't want to risk anymore so I shut it down right away. In this case that miner should have stopped hashing, all dropped to 0 and made my pool connections dead. But it kept them alive and kept hashing with no fan connected. That little box below the fan#2 and fan#3 is M's monitor program I had running. I set it to alarm me when the temp hit 80c. And it kept popping up on me when it did, so I included it in the screen shot.

Would it not be better to load the S4 firmware to the controller and then reload the S5 Feb release back?
Anyone try the custom firmware that was posted in previous threads?

[ThatsMe]

Remember that guy with the two blown chips and the side panels looked like they were doing the wave about two months ago? This is probably what happened to him. I thought something didn't add up in his story. Maybe he was the first to have this happen to his S5, it would explain the warping issue he had.

Hi, has anyone manage checkout on bitmaintech using USD?

[Rabinovitch]

I also found another screen shot of an S5 with temps over 90c+ from Rabinvotch. His unit didn't stop hashing or shut down either when it hit 80c.

Note that "Stop running when temprerature is over 80℃" checkbox was checked at that moment.

[adaseb]

With the S3+ unit does it stop hashing when it reaches 80C ?

This is just to let people know that my Antminer S5 purchase was confirmed paid by BITMAIN today so it looks like the logjam is being cleaned up.

Thank you BITMAIN!

I am, not emailed yet. Bricked a controller trying variations of the SD card OS instructions, never got them to work.

So, same controller as the C1 but not using the micro-SD card?

Along the lines of when the Ants update the GUI and how...
Anyone having 1 blade of their S3+ or s5 periodically shutting down with hashrate dropping to 1/2 and yet the ASIC status show all chips are are fine? Not until a soft reboot will the status show ----- for the entire dead blade.

Do a hard boot and all is well again for several days or weeks before they get lazy again. Out of the 37 Ants in my farm 3 s3+'s and 2 s5's do this. Can't blame the PSU's because all are ran off of server PSU's feeding 2-3 miners and the other miners on the PSU are fine.

I have had it a few times on my S5.  I am using a RM1000.   I just have to reboot even in gui and it fixes it. 

If it is really happening a lot you could use M's antminer monitor and have it automated to reboot if drop in hash that far.
