ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

I think they all expire 2/4, and you are right 370 isn't.

they probably have to hold the price so S6 would not look overpriced at 3-4th and $1100-1300.

i almost had enough bitcoin to get one of these when they were 15% off.. i hope they go back on sale soon or the price drops..

Ok far too many posts - both in the threads and on my profile as well!

Someone was really kind and gave me advice on how to use "TWO" PSU units to power "THREE" S5 Units.

Basically using 2 850s or 2 1000s and then running 3 miners of them.

Does anyone here remember the correct wiring to do so? Is it you simply dont power a single blade/side from two miners? 

Sorry; I've scanned through like 20 pages and can't find it - and search is currently disabled.

Thanks!

Thanks! I connected the 2 PCIe cables, up to now it seems to work great. I'll do a temperature check tomorrow.

Now I have to make this fanmod before the wife starts to beat me up.... :p
 

i did not dare to run it at default for more than 12 hr...
Everyone seem to be particularly affected by the S5 default fan sound. You want to stay as far away as possible.
what's your mod?

I replaced the loud stock fan by two 120mm fans I had in spare. The fans are in push-pull configuration and powered directly from the PSU (constant speed).
It makes my S5 really quiet, about the same as my desktop computer. But I had to downclock to 250MHz (~800GH/s) to keep the temp below 60°C.

So at this point I loose 30% of hashing power to reach an acceptable sound level..
Next step I'll try more powerful fans with the "fan shroud" trick mentioned by dog1965 (https://bitcointalk.org/index.php?topic=908494.msg10250546#msg10250546

I also noticed a big spread between the 2 temp sensors... Any idea what it could be??

That is correct.  Only 1 PSU per blade.  (Don't cross the streams!)

Just run PSU A to S5 X and one blade of S5 Y, then run the other blade of S5 Y and S5 Z off of PSU B.

Each PSU powers their own S5, then shares an S5 by each powering a blade.

Perfect thanks - we ended up giving it a shot that way and it's perfect.  Thanks for the help!

I've posted a guide on how we've configured our Antminer S5 Units - by clustering them on a small in expensive shelving unit and mounting them vertically.

We're able to keep temps well under 60C - and overclock to 393.75.

The vertical config works great - and we are only using a single fan system for cooling. (Delta Replacement Fan).

Here's a link to the Guide:    https://bitcointalk.org/index.php?topic=945775.msg10356519#msg10356519

       PSU A        PSU B

b1 b2          b1 b2         b1 b2
S5               S5             S5

Each PSU powers their own S5, then shares an S5 by each powering a blade.

hopefully this clarifies it a bit so people dont plug both PSUs into the sockets on a single blade

Nice concepts applied there, aka pointing the rigs up, though I suppose it limits the number of rigs in a space as you can not then stack another set atop them.

Looking forward to your forthcoming guide ..... had a glimpse of the initial thread before the party pooper reared its ugly head!

You could still stack. You would just need to block and vent 100% of the exhaust from each level.

But the unit also takes up 50% of its normal footprint when vertical.

So that considering as well.

Is anyone having issues SSHing into their S5? I can't seem to accomplish this, although i'd had no issues w/ the S1 or S3.

I changed the WebUI login password, but i've tried root/root as well as root/mypass.

I didn't see any options in the WebUI to enable/disable SSH access.

edit: I found it... root/admin. I think the 2nd post in this thread says to use root/root. dogie, should this be updated?

I had an interesting thing happen with one of my S5's

I had it running for about a week, then one of the boards stopped working - all x

I rebooted it and it started back up for about 15 minutes and died again, after another reboot it just showed all -

So I figured the one board dies and I would let it keep going with the other board, but as it ran the hash rate would drop for the next 20 minutes down to 0. Reboots would bring it back then about 20 minutes later it would be 0 again.

Frustrated, I shut it off and left it for two days.

This morning I decided to take a look at it. I pulled the cover on both sides and did not see any signs of anything burning/frying etc. I unplugged the power to each board one at a time and powering on to determine the bad one. Then I decided to try changing the plug on the controller board, unplugged it from the outer socket and plugged into the inner one. Upon powering back on both boards started hashing and have been happily humming along for the last 6 hours.

Great ideas.  Thank you.  That is also presented very well.  Good work!

Can you PM me or post back here in a few days how you get on with that, its an.... interesting result which may be useful. Is that an RM1000 I see?

[SuicidalCookie]

Today I added a Delta AFC1212DE which has 148cfm at 3900 rpm which is being run through molex so it's going full speed. I also have a second fan running in a pull configuration at 1800 rpm. But for some odd reason Row 1 is 58 degrees and row two is 44. There is A LOT of air being pushed and pulled through this miner, why is one side way hotter? Should I RMA? I've only been running it for 5 days. I should also add I'm running it at the stock 350 setting. So no overclocking. Also the temperature in the garage is 58 degrees Fahrenheit / 14 degrees Celsius.

EDIT 1: It has now started restarting mining every 7 minutes or so. It will be at 1Th then all of a sudden drop to 0 and then start to climb back up. There are no X's.

Yeah I thought it was interesting too, that is why I posted it.

If something happens I'll let you know, but still going great right now.

RM750

I use all Corsair for my miners.
RM750 for each S5
RM850 for each set of two S3's
RM1000 for each set of two S3+'s

Nothing un-usual about the 58, 48 temp readings (mine has 44, 50 at night-time and up to 52, 59 day-time with just an S3 fan), but worrying in your instance are the restarts .... you need to get in touch with some-one directly at bitmain.
