and "NEW": Hashnest PACMiC V3


..........................................................................

This is the miner that should be called the Widow-Maker. xD

I need to get more S5's instead, they're not too bad with the fan control and i'll prolly change the fans for quieter and better cooling yet.

Nice!  The price is pretty good. Not perfect but pretty good.
Like you Phil I can get 1 because of the sound. 

Had a feeling that they were low power.

Well the beast is selling now on bitmaintech website

price is  2375 with 98 to ship to usa or 2473  not bad.

if you have a low power cost  setup  this could do well.


I went with bitmaintech's new cloud offer .  I purchased 10th for 6.66 btc   

I can not justify getting the 7.7th beast.  due to  the noise  my wife would kill me.

OK understood. On my test I just unplugged the PCIe connector to one of the hash boards. I did not  unplug the 18 pin connector to the same board, perhaps I should have?

Just repeated the test with both connectors unplugged. Revise Controller current sligtly up at 0.5A so 6W.

The 4-pin connector is just for power I believe, so I never disconnected that - if it were, then BB wouldn't have any power to do anything (or power fans, etc).  The only things I unplugged were the 18-pin blade connectors (used to control the blades) and the 6-pin PCIe connectors (used to power the blades).  I did disconnect the fan and hook it up to another power supply, just to remove one of the variables from the mix.

That is good looks like we are in the same ball park. I did not unplug the Controller Connector when doing my test. I unplugged the other blade. I sort of assumed that things would not run with it unplgged? Which begs the question what is it for? I had measured 9V on it and assumed it was for a purpose?

EDIT. Assuming we are talking about the 4pin connector between the hash board & the controller I tried unplugging and nothing worked

I think your methodology sounds correct, so I've stopped being lazy and just run a couple quick tests to compare.  I'm using a Watts Up Pro ES to monitor power at the wall, and I have the fan hooked up to a separate power source - so the only things that are being powered are the BB, controller, and two blades.  All settings are the factory default, PSU is the Corsair HX850i at 110v:

Bassline - 558w: I booted it up and had it mine for a couple minutes like normal, hashing is right within spec.  Keep in mind that the fan is NOT included in this.

One Blade - 275w: Physically unplugged both the controller connector and PCIe power plugs from one blade - software ran like normal, although the hash rate was obviously 1/2 of normal.

No Blades P1 - 14.4w: I left the PCIe power connected to only one blade, but unplugged the controller connect - so no blades are actually connected.  Everything booted up fine, but no hashing.

No Blades P2 - 17.6w: Similar to No Blades P1, but this time I hooked up PCIe power to both blades, but left the controller connectors unplugged on both.  Everything booted up same as with P1.

Zero RPM P1 - 68.3w: This is running with their latest firmware, one blade connected correctly, but without the fan connected so it won't do any hashing.

Zero RPM P2 - 127.1w: Same as Zero RPM P1 but both blades fully connected correctly, but without the fan connected so it won't do any hashing.

Bassline+Fan - 580w: Latest firmware, fan set in software to 100%, both blades connected and hashing correctly.

.... So, now some insights from the numbers - a couple things stand out:

#1, with a platinum PSU (at 110v no less), it's beating the spec and doing 0.502W/GH (at least this particular unit)
#2, the overhead of a blade is 3.2w, regardless of it doing anything
#3, the BB+controller is somewhere between 8w and 11.2w
#4, the overhead of a fan (full speed) is 22w
#5, with the new firmware, when it benches a blade, it still consumes 58.8w

And back to the original comments about system savings, being generous the S5+ saves 89.2w (6 CPU/controllers and one fan) over 7 S5's.

Anyway, hopefully other people find these numbers helpful, or at least interesting...

I measured the controller current by making one measurement with 2 Hash boards connected and then with just 1 hash board connected. The difference is the current that a single hash board is taking. Multiply by 2 and take it from the number you first thought of  & the have the Controller current.

So the controller takes just over 0.4A, so controller Power is only 5W. So unless there is a flaw in my methodology not much of a power saving from sharing the controller.

Ok that is good. Does anyone know what the additional 2 pins are for, or the additional push button on the 18 Pin controller?

You can use new S5 Hash PCB  ( 18 pin connector)   with S5 Control PCB  (16 pin connectors) Need only a 16 pin cable.
Picture of my water cooling S5 project    3 x old blade + 1x new 18 pin blade.



Click on the image

It has got the 18 pin blade connector so you will need later hash boards (V1.91) with the 18 as opposed to 16 pin connector. I do not know what the additional 2 pins do, or if they are anything to do with the additional button on the controller board, or if a 16 pin blade can be used with a 18 pin controller? Perhaps someone does???

Rich

Excellent points - I'm planning on building one quad-blade machine just to kind of prove things out, plus I have a water cooling kit I haven't built yet, so it's a good excuse. 

If I SSH in and kill CGMiner, then it runs ~17w pretty consistently - it's once CGMiner runs and that it's not hashing that it maintains that pretty constant 50w for several seconds regardless of clock rate, then it kicks into gear and starts really hammering power.  But to your point, it could also be some characteristic of the ASIC's starting up, and not additional load of the FPGA starting up.

I also emailed Bitmain to see whether or not the new controller is compatible with the existing S5 blades - the connectors look the same, so if is, then it might be possible to cannibalize 4 S5's into a single mini S5+ - maybe call it an S5- perhaps?    It really depends on whether the controller ASIC just detects and adapts to the blades, or if it's got specific firmware on it for the newer S5+ blades.  At worse, even if it's not compatible, they'll hopefully sell me the cables which look to be much longer, so no need to hack up my existing ones.

you flux between 17 and 50 with no hashing.  It could stay stable at 17 when hashing.

 But for arguments sake  running 2 s-5's and using 1 controller.
then running 2 s-5's and using both controllers will give the true controller power draw.

17 is meh 50 is not.  

If I run 6 s-5's on 3 controllers I would save 150 watts. which is  about 110 kwatts per month.

But I read a post saying voltage was dropped to the chips on the s-5+. So I suspect your 17 to 50 with 0 hash while accurate has something to do with real numbers while hashing. along with the voltage setting dropped.

If you could run 2 s-5's machine on 1 controller and check watts  say 1150 is the watts.  then run 2 s-5's with  both controllers  and get 1200 watts  then you are correct.

I think you may get 1150 then 1170  my guess is the 17 watts number is more accurate not the 50 when hashing.

no I mean like we get a few guys interested to split 1 or more s5+ miners and the trusted member ships the boards to the people that paid accordingly but trying to get a good price point would make it hard to do. I'm more interested to see if they sell replacement boards for this. I have seen about 3 different listings for the s5+ on ebay and they are in the US.

I looked over some power monitoring data I've been doing on a S5 I have - and when it's not hashing, and when the fan is on another power supply, it looks like it consumes about 50W (it periodically dips down to 17W, but for the most part 50W seems to be when it's doing something with the FPGA, but hashing hasn't begun).

If that's the overhead, then for 7 S5's, it would be 350W total for BB/controller - and without the BB/controller as part of the power calculation the S5 drops from 0.51W/GH to 0.46W/GH (pretty close to 0.44W).  Now 7 S5's is obviously 7 fans and the S5+ only has 6 - the fan at full power consumes 0.20 amps (~24w), so the system savings would be 324W over the same S5 configuration.  Not bad, more than 1/2 the wattage of another S5 by just changing the configuration around a bit..

From this I would say that they've done almost nothing in hardware design to increase efficiency of the S5+ (as opposed to the work Sidehack has done), and instead have made their gains by optimizing the system.

Center section only.   Can't see myself wasting more on + models.  The wait has been long but will need to wait a little longer (biting lip).

Do you mean head person gets one whole miner?  On a miner at this price it would need to be a large group buy to provide person in charge a miner.

I think our best bet is if they add it on bitmain's main site.   As of right now I would say they want to keep it more local in China market.  I am not sure we could get a price that ROI is possible.   Current price is high.  To ask Bitmain to work with a small group and to lower price is going to be hard.

I predict this miner mainly goes into China data centers for better or worse that is main market.  And most of us will be waiting till next gen.

so 48 chips per board so that would be ~855 gh/s per board, and if they kept it simple (like they usually do) they would of used the same pin-out so I would say the boards would/should plug into the s5 controller and work fine. we should see if they sell just *replacement boards* for this miner and then it would be like an s5 upgrade and could possibly tweak it to get better efficiency than the stock s5 boards. seeing how 2 of these would put an s5 at 1.7 th/s and the stock controller can take up to 4 boards, I would be fine loosing some gh/s for better watt to ghs than the stock s5 set up. this could get interesting.

we could also do a mini group buy, a few pitch in on the s5+ then the head person gets the miner and ships out boards as paid for.

Lktec probably in December per a few comments I've seen. Might be as early as this month but I suspect their August 20 announcement is more likely to be "more exact specs" and possibly "you can now preorder" their unit(s). Not sure if they're going to be SFF though, their previous units weren't real small.

Possibly Innosilicon with a direct unit of it's own around the same timeframe, but their previous unit was a rack-mount size design not SFF.

In theory SFards should have the SF100 available in retail quantities by then, but I want to see how reliable those are going to be at the BOARD level - Gridseed tended to be GARBAGE as a board-level designer and so far what little feedback I've seen on the SF100 is VERY much "more of the same bad design work" or just bad manufacuring/shipping causing too many dead units.

In theory the Avalon project could have something out soon - they've been VERY quiet for quite a while, have had plenty of time to get a good start on a "next gen" product past the 4.1

no one is selling us gear except bitmain.

sfards is just way too high priced.  and while I have seen a few photos no one has done a real review of one.

Pretty sad that now only bitmain will do small form miner.

Lets hope lketc will provide one too but Im pretty sure they will not be able to fight bitmain.

well lets say it goes for 2750 + 150 to ship that is 2900    for a .445 watt per gh .

so you could buy s-5's last jan for 310 plus shipping.  But we had a price war s-5 vs sp20

On thanksgiving last year sp20 was 600 and 5 of them would be 3000 usd   and do 7000 gh at 4600 watts.

But btc was about 400 a coin last thanksgivng   so we may have been better off with those sp20's

also paycoin made 5x to 10x the coin if you rented to nicehash.  that meant 75 days worth of coin in about 13 days.

So last fall you could argue was much better to buy gear.

We then crashed btc  price once bitmaintech went into the price war against spondoolies.

I would argue we are yet to recover from that price war.

for those "committed" the full setup of 3450 watts would make sense.  set it up in the basement on a 220v dryer circuit and vent outside would be ideal.

a home miner would go for mid range @ 5th @ 2300watts is just perfect for a 20a 110v circuit.

although the price is quite high.

am i off or does this seem more expensive then a year ago?  forget the difficulty difference.

I'd be a TON happier with the S5 if it had an undervolt option (per the ORIGINAL claims for it).

 I agree that this S5+ isn't targeted at home miners - still think it should be called the S6.

This also makes me wonder if the S5+ hashing boards will work with an S5 controller? It will be interesting if/when somebody that's interested gets their hands on one to start taking close-up pictures and measurements, both physical and electrical.

The current 7.7 TH miner make complete sense if you figure that they want to sell to big mining farms. It's got to be somewhat lest costly to manage N S5+ miners than 3N of something smaller. Not to mention some reduced cost for a single "bigger" controller compared to the existing S5.

It just isn't a "hobby" (used to be "home) miner. (Hobby term stolen from Phillip).

Not too long ago, one of Bitmain's account here went and said that they wouldn't be doing tape-out of the "new chip" and that they wouldn't be selling it soon because competition failed to achieve a better/efficient chip.

There's probably already design and testing units in Bitmain's HQ, but besides that, there's no telling if/when a new product is coming out soon-ish.

Also... i was just joking

I'm pretty darn happy with my S5s as it is

Im still able to do some profit with the gear so I vote for option 3. Center + options left right. 

Also if your power costs are low the s-5 at 352 can earn a profit for many miners.

I would argue bitmaintech is not the terrible villain people think they are.

Diff has had slow steady growth mostly due to bitmaintech not blowing out s-5's at 310 usd a piece.

While my mind wonders what btc would be like if the Asia builders kept selling to the public at decent prices

I do not think the current status is all that bad.

There's nothing to suggest, beyond speculation, that a BM1386 actually exists. The S5+ suggests that Bitmain has plenty of BM1384 parts for now.

How about option 6?  The "I'm not giving Bitmaintech another satoshi or red cent".

It blows my mind that people are still buying HW, let alone from these clowns.

How about:

size matters  the center piece is almost the same size as  1 s-5 and does 2x the hash.


BTW  if the 3 pieces do 3450 watts  each 1 does 1140 and 30 watts for the controller  .  so the middle piece would do   1140 + 30 or 1170 watts

if the entire thing does 7750 gh 1 does 2583   so 1170/2583 =

.4529  s-5+   vs    .51 or .52  s-5

so you are off by a lot.

And I am certain 1 middle piece would ship far better then 3 piece set.

and If a  order 1 center piece today  and I center piece a week later  I have 2 controllers  when I only need 1.

How many 'my controller is dead posts' are on this site?  I have no idea but I bet there are hundreds.

It is a fun poll and bitmaintech may read it , but they sell how they want to sell.
I know the center piece would sell well.

I am on record as wanting one from them at a reasonable price 900  and a 5 page review is reasonable to my way of thinking. I would be open to an offer on their part


This would sell and sell better then as  three piece beast.

Just for fun poll,  i choose option 2

The BB should be low, like < 10w when it's up and doing things, but the FPGA could gobble up a decent amount of power depending on what they're using it for.  Obviously fans are a hit to efficiency as well, but I wouldn't consider them part of the CPU costs since they're blade-specific in this case.  FWIW, if they're the same fans as on the S5 I was just doing some power tests with them the other day, they consume about 0.20 amps at 110v (full power) - so if this thing has 6 fans, you're talking 1.2amps for fans alone, or almost 10% of the overall power consumption.

philipma wrote about the fact that it is worth looking into buying s5 instead of s5+ . Looking at the price.
And here we have a new deal to s5 . Only 352 USD ( 1.323 BTC) .
It seems that the weight of the parcel jumped to 4.2kg . They can now sell a version with small heatsinks or I missed something ?

 I wish I had the kind of money available to say that.

 8-(

What do you expect the controller's consumption to be, like 10W (ex fans)?

yeah, 0.44 vs 0.51 is a small difference anyway

If they did break it up in the way you proposed, I would imagine that the middle (controller) cube's efficiency numbers are going to be much more like they are with the S5.  Right now the overhead of the BB and the FPGA are spread across  all 3 cubes - but now it would be just the one.  At which point, you might as well just pick up some S5's. 

I think it's best either beast-mode S5+ or just plain old S5's...

Personally i'd like just individual units. The thoughts of linking them together isint bad, however... It might just become a pain if you need to separate them and the sides can't do anything without the center. So you'd have 3 unit goes down with a single point of failure. I think i'll stick to S5's for now. Hopefully this loosen some S5 that someone can sell me after they get these. (lol)

So if i could have it my way, i'd take them as a real S5+, a single unit.

Yeahhh, you wish. That single middle unit thing drain 4time the power of a S3. ^_^"

Voted option 1 as well! MMMM only if i had enough cash to get my hands on couple of thousands

Just for fun... want to get a couple of those beasts....

just make it 2 or 3 new boards and call it s5+

that thing is not s5+.... is an s6- or something like that

Full disclosure: Voted "Just the center piece/controller/ 2550gh/1150watts", but I wonder how the noise is like on these things.

If (dare-to-dream) these are as quiet as the S2's or S3's, I would be awfully tempted in picking up a bunch to replace all my underclocked-S3's, S5's and SP20's.

Do you think the s7 will be compatible with this s5+? If the s7 is a totally diff chip and controller it might not be possible

I voted 1 time :

to be able to add an s-5+ right away  or an s-7 piece later.

Okay

option 1  antminer sells it the s-5+ as is a 7700gh 3400 watts beast for 3000usd+
option 2  antminer sells the center section as stand alone with the controller  about 2550gh/1150 watts
option 3  antminer sells the center section/controller with an option to addon left right  pieces  so 2550/5100/7700
option 4  antminer sells the center section/controller with an option to addon left right pieces of the s-7 in early oct



Fun poll   since we have nothing better to do.

It also could let antminer know what we would buy more of.

I would be willing to buy a center piece and do a review of it.

Note I don't want a free one.  But I would only want the center piece and controller if they would part with one. So I could review it.
