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

[shadow1975]

Yup those deltas wont work on the controler, but you can connect them directly to the PSU and have them working 100% rpm which is what you want at the end. And that way if pool goes down or internet goes down your device wont be fried...

Sorry for my question, but how can I connect this fan directly to PSU ?

Pretty much all PSU have a 12V and a 5V so depending on your fan ...

[FlensGold]

Does anyone have an idea how to solve this?


The S5 miner is starting as normal, all Asics are being detected and it has connection to the pool (also tried other pools).
It is powered by an Corsair CX750 PSU (as it has been earlier), but it does not really start hashing.

You have updated the new firmware? try to return to the previous firmware and it'll work, the latest firmware which issued and shit

Yes, I updated to latest firmware and was facing this problem. Then I returned to the one from April (previous one) but have the same problem. I did not have this before updating to latest FW.

Quite a few hardware errors there. Got a different PSU you can test with quickly?

Could be one of many reasons and there could as well be many ways to resolve.
1. Completely power off the unit, pulling the plug(s) from the wall and leave idle for a few minutes then power up again.
2. If you are powering your unit using 2 PSU's make sure you switch on the PSU powering the board to which the controller is connected first (even better switch both on at the same time).
3. Your PSU may have let go, try powering up using another PSU (if you have one), or switching the PCI-E plugs about. Observe the HW errors ......

No idea why some folks have having trouble with the latest FW release... I've so far done 15 of my S5's with zero problems. Hash board revs range from early Batch-1 up through last new Batch.

The one problem I * have * ran into is several of the latest S5's even with the older as-shipped version of firmware is that M's Miner Monitor can't reboot them via ssh: "incorrect password'. Ok -- so what is the new one the miners ship with?

[QuintLeo]

I think they should make another batch or two of s5's.

 Why?

 It's not been announced, but given how many used S5s they're selling from Hasnest and their own site, it's pretty obvious they have the S7 in production and are replacing their "own farm" S5s with them.

[QuintLeo]

Needs more pci-e connectors...

So you tape 3 S5s together and call it a new machine?  Color me unimpressed.  Sidehack got much better efficiency out of these chips; Bitmain isn't even trying.

 Not quite right.
 3 strings per board, though only 16 chips per string so the efficiency IS a little better than the S5.
 Just not MUCH better, IMO they should have done 3x 18 strings or 2x 20 strings per board to get some GOOD efficiency.

 Also IMO they wasted the 3'd PCI-E connector on each board, even 2 per board would have given plenty of overhead for significant overclock (with the lower voltage per chip these aren't going to overclock as high on average as an S5 anyway).

I suppose their thinking for a 3rd PCI-E connector is when / if you used (cheap) PSU's with say 18AWG cables, you'd be able to make it up with the third.

I believe you are correct there, Sir.  I'm just wondering if the IBM 2880W PSU's can push one of these...?  I have 14 extra laying around.  They only need breakout boards.

[dmwardjr]

Hey dmwardjr

haven't noticed you in while how are you ? , how close have you come to that 1 PH in your home ? .

just saying HI

cya .

Hi toptek,

Good hearing from you...

I've been staying right where I'm at (just under 60 TH/s) with S3's, S4's, S5's and SP20's.  I'm kind of on the fence about going to Washington State at the moment (50/50).  Plus, I've been saying [For quite some time] I would go some time in quarter 4 of 2015 or quarter 1 of 2016.  If I go, it would more than likely be quarter 4 of 2015.

My power costs have been going up quite a bit here in Alabama.  I'm still making money but nowhere near as much as what I could make in Washington State.

I've been doing research on loans to get a kick start in mining with 1 PH/s out the gate.  However, I do not like what I'm seeing with these loan offers.  This means I would only be willing to invest approximately $90K maximum out the gate with my own cash getting started.

I've also been looking into trading pairs on FOREX lately.  I'm going to school online at http://www.babypips.com/school and learning a great deal about trading from the first 5 videos on FOREX at http://theinnercircletrader.com/Tutorials.htm.  The other videos on trading are great as well.  I'm going to start trading on FOREX with $5K in a couple of more weeks just to get a feel of it while putting only a small amount of my funds at risk.  If I do well with it over a couple of months, I may go ahead and add another $50K to my account.  Then, use gains from that [If successful] to start off in Washington State with more than the 250 TH/s I could start with right now.

It's quite a gamble to move out to Washington State.  If one is to move out there, it needs to be no later than the end of Quarter 4 of 2015.  The reason I say this is to allow yourself to ROI before the block halving.  What happens after the block halving remains to be seen.  I would hope it would be at least double what it is right now but who knows.

Needless to say, I have a lot of options I'm considering and remaining patient while trying to make the correct decision.

Cheers M8

Hey dmward,

about the 2880W PSU's, I wouldn't personally power these 1 for 1, although the PSU's come a bit under-rated, I don't think they would last with 2-300W over their rating in a steady state. They would likely hit the thermal shut off, especially in this summer heat.  Also, the higher you run PSU's, the lower efficiency gets.  It would make more sense to run 2x S5+ with 3x 2880W PSU's @ ~2100W on each PSU and get the best power efficiency at the wall.

With appropriate cables like are available for thes server PSU's, 2 per board would be more than sufficient. The good aftermarket PCIe-PCIe cables are rated for 288W per connector.

do you think if he clocks at freq 275

power drops enough?

275/325 x 3450 watts = 2920 watts.

I actually am interested  in what was done to go from  .52 watts a gh to . 445 watts a gh.

the s-5 is freq 350 and does .51/.52
I have tested the s-5 from freq 250 to freq 412   and power is really flat about .49 to .52 going from

freq 250 to freq 412.

I wonder how flat power is here  going from freq 225 to freq 375

if this could do freq 275 at .4 watts it would make for a bigger improvement .

my sidehack usb sticks do .35-.36 at freq 250

this gear did something to improve from .51 to .44   not just the downclock from 350 to 325

I suppose their thinking for a 3rd PCI-E connector is when / if you used (cheap) PSU's with say 18AWG cables, you'd be able to make it up with the third.

 BTW - based on my research 18-gauge wire in a common PCI-E cabling setup should be good for 7-8 amps at 30degrees C (NEC code doesn't appear to go below 14 gauge, so I had to extrapolate from wire cross-circular area) - so yeah, it would be definitely marginal vs. the capasity of the connector. Still plenty to handle the under-200 watts per connector of a S5+ on a 2-connector setup though unless you get the thing to overclock a LOT. On the other hand, cool running cables are a Good Thing so the third connector doesn't hurt anything (except perhaps the price by a few bucks or so).
 Keep in mind that the "3400 watts" is the usual Bitmain "AT THE WALL" spec, the actual draw on the connectors would be more like 3100 watts total or ballpark 14.5 amps per connector on a 2-connector setup per hash board, since they claim to use a Gold-rated power supply for that spec (but never really state which one they use, some are a little MORE efficient than others).

[QuintLeo]

I actually am interested  in what was done to go from  .52 watts a gh to . 445 watts a gh.

They went to 16 chips per string, dropping the chip voltage from .8 to .75 - the BM1384 has a LOT of room to be more efficient via undervolting, sadly nothing out there except for one stick miner ever did anything with that ability to a significant degree (I don't count the S5+ change as significant).

 S5 doesn't seem to change efficiency much at all just via underclocking. Small enough to be measurement error rather than any actual change.

 I was thinking about a move to the low-electric-cost part of Washington State at least a year before I ever started Bitcoin mining, the mining just gives me more reason to go once I get a viable amount of cash saved up for the move. Summer rates here in particular are insane - there's a REASON I turned off pretty much all of my d.net and gimps machines in mid-June. If I had 60TH of mining power I'd already be GONE.

Yup those deltas wont work on the controler, but you can connect them directly to the PSU and have them working 100% rpm which is what you want at the end. And that way if pool goes down or internet goes down your device wont be fried...

Sorry for my question, but how can I connect this fan directly to PSU ?

Shadow,

Sorry to hear the 3.9 amp fan you chose did not work.  I bought all of my fans initially for my S4's.  I assumed they would be fine as well for SP20's and S5's.  It appears now I could be mistaken.  I paid more attention to CFM and RPM rather than amps or watts.

I hope your rig is not ruined.

Does anyone here have specifications for the watts and/or amps for fans with the S5?

I'm not sure about the fan someone else recommended that does not have quite the RPM's the BITMAIN fan installed in the S5.  Bitmain's fan could easily go up to 4,000 RPM's.  The one someone recommended was 3700 RPM's maximum.

The only fan I'm aware of at the moment to offer greater than 4000 RPM's with a lower amperage than the Delco 1212 series fans is the following:  http://www.amazon.com/Sanyo-Denki-SAN-Ace-120mm/dp/B00QWB1X3O/ref=sr_1_fkmr0_2?s=electronics&ie=UTF8&qid=1439317263&sr=1-2-fkmr0&keywords=Sanyo+Denki+SunAce+120+9GV1212P1J091

Here are the specs for the fan:

Sanyo Denki SunAce 120 9GV1212P1J091
Voltage: 12V
Power consumption: 6400RPM 36W
Rated current: DutyCycle 100% @ 3A
Air Flow: 6400RPM @ 224CFM
Noise: 6400RPM @ 64 dB-A
Air Pressure: 6400RPM 36.82 MM-H2O
Life Expectancy: 40000 hrs @ 40°C
Connector: 2510-4P


CONNECTING STRAIGHT TO PSU:

First, you may need to get a 4-Pin Molex Male to 6-Pin PCI-E Female Power Adapter Cable if your PSU did not come with this cable included. Some people are using server grade PSU's with custom made breakout boards that more than likely did not include the cable I mentioned previously.  Here is a link to several choices of that cable:  http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Delectronics&field-keywords=6+pin+pcie+to+4+pin+molex

Second, you may need to get a 4 pin molex to 4 pin fan connector if your PSU did not come with this cable included.  Here is a link to several choices of that cable:  http://www.amazon.com/s/ref=nb_sb_ss_c_0_34?url=search-alias%3Dcomputers&field-keywords=4+pin+molex+to+4+pin+fan+connector&sprefix=4+pin+molex+to+4+pin+fan+connector%2Celectronics%2C167&rh=n%3A541966%2Ck%3A4+pin+molex+to+4+pin+fan+connector

I just find it very odd the fan could hurt the rig.  If anything, it's the fan that could be harmed by not having enough amperage supplied from the rig instead of the reverse.  

I honestly belive your S5 only needs to be shut off for a while [Maybe after doing evening a hard reset] then turn it back on to see if it begins to hash.

Let me know how it turns out.

PS - IF someone knows the specs on how much amperage is provided by the rig for the fan(s), please let us know?

Sorry i don't know the actual stats some one told me once but  now i can't recall then but i do remeber don't go over  2 amps if he didn't keep trying to make it work , turning it off, unplug etc  then doing a hardware reset should fix it .

 fans have  to be below 2 amps for the S5 these work  just fine on them i use them on my S5's http://www.amazon.com/gp/product/B004Y1HLA8?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00  I have OC with two of these  fans on one S5 with no temps over 60 c so i know they work well . Sense i don't like OC i usually dont much but i run two S5 once @ 400 for two days. HW error were low enough and no temps ever went over 60 C but most of the time or all of the time i keep my S5 at 350  unless something goes a mess then il OC them just to get back on track . that's if speeds drop for no reason etc  and a reboot won't fix it. if this helps it doesn't have to be a PCEI cable most fan come with the right converter plug or molex and even  G-blade does it just plug it in using one of the Sata plugs from the PSU that has the 4 pin molex on one end all ATX psu come with that unless you buy oem, the fan all most all ways comes with the right converter plug .


with the fans I use he needs two and do it push pull which make better sense then have one and stand them up it does lower temp 3 to 4 degree or more standing them up using a box fan didn't work for me it made the S5 temps go up and work harder .



IN fact atm  all my S5 use one of these each http://www.amazon.com/gp/product/B004Y1HLA8?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00 as push and one of these as pull http://www.amazon.com/gp/product/B00A460TK6?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00  i used to have two http://www.amazon.com/gp/product/B004Y1HLA8?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00  Phillip made a post to some else about noise so i tried it and it work well for me on 4 S5 , i have 9 miner in my house atm I'm about to my limit i want ever .

Thank you very much for the information you've provided from "actual" experience.  I see now I should not connect the 4.9 amp Delta's I have in storage to the S5's.  I should keep them on reserve for the S4's.  I've installed a total of five of these 4.9 amp Delta's in S4's thus far and they have worked great!!!  All of my S4's are batch 2 and I have yet to have problems with factory PSU's [Knocking on wood].  Only fans breaking down.

Thanks again for the very informative post!!!
