The shipping of B5 started, 7 days earlier than promised date. We added more B5 units for sale.

What about B4 ? That hasn't even started shipping yet has it?

Mine shipped on 7/29 and is scheduled to be delivered on 8/1

When did you order?

ANTMINER S3 -B4 × 4 @ 2014-07-24 22:28:43

B4 x 6 @ 2014-07-24 14:45:04

Thanks. Maybe they have actually shipped and I just haven't had the notice - that's happened before a few times...

Nice to see a fellow from my hometown Nottingham

Dunno about that Liverpool avatar though! Tongue

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience..

I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months.
(I'm a newbie regarding mining, so with this miner I can use it for multipools right? Grin

)

I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks. Here is a list of the historical increases.

https://bitcoinwisdom.com/bitcoin/difficulty

In the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months.

Bitcoin mining is nothing more than an "arms race". You need to keep increasing your hash rate to keep up with the increasing difficulty if you are looking for "steady" income.

Several hours ago I posted a screenshot asking why I do only have ~250GH/s while the miner is powered with a 1600W PSU and all ASICs looked fine. I restarted the miner and let it run a few hours. Now it looks like this:

It seems that some ASICs can not be detected. What can I do in this case?
Thank you

try diferent PSU (yes i know its 1600W, but really sometimes just PSU is bad)

The thing is that the temps are so low on chain 1 in this pic and your previous one. Something is not right with that first blade. As others have said check out the thermal paste but I think it may be something else. I would contact Bitmain for a RMA.

Your temperature on one of the blades is too low. That means some chips are not running.
That's why its is shown as "-" in the ASIC status page. "-" may possibly be damaged chips. not sure about that.
One of the fans speed at 2340 is also a bit higher than normal.
All the above leading me to think its a heatsink problem. Maybe the chip died after overheating.
Try to remove all the front and backside heatsink and check.
Also try interchanging the PCI-E power cables before going for a heat sink check.
Hope you are already in discussions with bitmaintech.

Check your cables. Open the cover of the S3 and make sure that the both blades have their cables plugged in correctly.
That one board is just not hashing at all. That's why the temp is so low. If it's not bad power (PSU) or cables it's likely an RMA.

Have you taken the unit apart and checked your thermal paste?

When BMT recommends checking the thermal paste, are they talking about the front-side or back-side heatsink?
There are two per blade. Is it pointless to remove backside because there are no SMCs?

They are talking about front side (the ASIC side) small long heat sinks.

Yes "warranty' have not much value in the mining hardware.
41 - 42 was my temperature peaks at stock clocks.
I don't have any link to the thermal grease for now.
I'm searching for it to buy the same brand or the alternative one having >3 conductivity.
But most of the products I'm seeing is of conductivity 1.
I will post here the link if I find it or some else who has experience in doing this will support here.

They are talking about removing the front-side heatsinks, right?

Yes its about the front heatsink which is directly attached to the ASICs.
Need to check how efficiently they did the inside heatsinks.

Excellent - I'm just waiting for my wallet to synchronize...

Why not using Electrum or Multibit?
Instant synchronisation with the block chain.

Guys: I been testing a few SP10s in a room in my office, normally the temp is 90F degrees because I have 4 of them in a small space. One day it was 100 degrees in there! The end result what the miners worked great, and I am actually moving them to the datacenter today.

Question: What are you thoughts about running this S3 at 80F? 90F? 100F environments? Would they just shut off? I may test today at 80F. The way I make the temps go up or down is to turn on more miners. I have a room for testing, but there is no ventilation in there. Its a big room, but it heats up fast. Would love to hear who is running at what room temperature. I am sure 80F and below is no problem...

I run 4 S3s at 107F continuously for days. Rock solid. Graphs to prove it.

Great info! I will try mine today in that room!

up to 85F is no problem for both S2 and S3.

No problem with S2 at 160F, but if you go somewhat beyond it will shutdown.

Has anyone received coupons from Bitmain for Batch 5?

I did not, and initial coupons were only for Batch 1-3.
They could still issue coupons later on, but there was no announcement re this.

up to 85F is no problem for both S2 and S3.

I've had S2s run up to 85F and had no issues - haven't stress tested any S3s with high temps as of yet but going off previous results, you should be fine in the 80-90 range. Triple digits, I wouldn't suggest - probably start to see the hash rate drop a bit + wear the units out faster.

I will test today in my back room. Thanks for the input. The fans on the SP10 are super high RPM, and these seem to be not as high. I will also look at putting in different fans in these guys. Any thoughts on 110v fans, or would that be a waste?
