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

Is there a s5 or s4+ coupon campaign going on?

Do not believe so.  It has been a while since last coupon campaign.   They seem to be using for compensation if price was lowered or other things last I remember any being mentioned.

They were at one time blasting out the coupons, but it seems they have moved away from that model of sales.  It was a nice perk for return customers.

When you go to 20nm process technology?
TSMC is taking orders at affordable prices since 2014.

I expect you'll get the answer to this question then Bitmain announces a new generation of ASIC, not just a repackaging like the S4+.

You might find that Bitmain has a different view of what constitutes "affordable" than you do.

1) Development of topology ASIC
2) Production of masks for photolithography
3) Protection of intellectual property

For the entire set - 160-200k ..
You can haggle ( looking where to place an order ) .

I think for BITMAIN this problem is solved.

A week ago my second S5 arrived. I've ordered it from batch 5 exactly 1 month after my first S5 (which is also from batch 5). The new S5, however, was different. It was better! I haven't seen photos of it anywhere yet, so I've decided to post mine here.

First, the outside look:

Exactly the same as any other S5. But, when we turn it around and remove the plastic side panels we uncover this:

Very cool, perfectly sized heatsinks outside of the hashboard. Don't know what kind of adhesive they used and how good it transfers heat, but it is definitely an improvement over my first S5, which doesn't have these heatsinks. My both miners have the same version of hashboards - v1.91.

For some reason both hashboards have 2 exactly the same chips without extra heatsinks:

The inside heatsinks have been cut in a little bit different way as well. They no longer feature 6mm gap between them the whole way for cold air to just run through the miner. The gap exists only at the ends of the heatsinks. This results in much better cooling efficiency. I haven't taken a photo of that yet, but I might do one for comparison.

I've already modded both of the miners and will write a thread about that today.

Wow these heatsinks are awesome! at least some update on the S5

They do look very nice.  I'm curious someone with new heatsink can you post your normal temps?  Does it seem to keep it under the 50C mark consistently?

Thanks to anyone who does it!

It will be reducing chip temps but it might not be reflected in the readings due to that temp sensor reading a generic PCB temp.

Indeed!  I'm glad to see Bitmain trying to cool off and improve the S5.  Thank you Bitmain.

I would also be curious see some real world temp difference, reported in the GUI and with a laser thermometer (rather than some guesses).

Thank you Vorta for watching and making the post, which great pics no less.

I have one, the change is negligible compared to the other S5s.

actually this looks like 1st gen ones where they used the s3 heatsinks instead of the newer specific to s5 heatsinks..


only bitmain tho can tell us for sure.

Has anyone used NiceHashe's custom firmware for the S5s? I know it runs a newer version of cgminer that the latest Bitmain one. Wonder if there are any advantages/GUI updates with the nicehash one.

Also what  they typical HW error rate or these? Im getting .1% on one and .003% on the other. Even though they are both really low one still produces almost a 1000x extra hardware errors.

I run the Nicehash FW with Westhash for both my S3 and S5 and the result is clearly superior -- I presume it's due to extranonce support!

It is due to that.  Thanks to Smit we have that option on a lot of Bitmain gear.  If you are going to mine long term on nicehash/westhash it really will make a difference on speed which leads to higher pay.

So for those pools it's a great tool.

Whats your reject rate? Im constantly getting around 5% for both my S5s, and im running the Bitmain 4.8 CGminer version that has extranonce support. (just at NiceHash BTW rejects on other pools is < 1%).

Using Smit's, my reject rate was around 1% on average.  It'd spike from time to time, but setting right back down to below 1%.

There seems to be a general assumption that extranonce is supported by the latest CGminer.  Is it so difficult to understand that there's no support for that assumption?  The CGminer version is either designed to accept that spec or it isn't!  If you plan on targeting your miners at either Nice or WestHash, then I suggest you install a version of CGminer that supports their specified (no secret) communication protocol.  Surely, that shouldn't be rocket science!  Wake up people, smell the roses!

hello
it is possible to change the clock automatically?

i will love have my ant working at 300mhz between 08:00AM to 23:00PM and 400mhz or more between 23:00PM to 08:00AM

+1

or/and

IF temp>=55C for period of T=x min, downclock for one step
and
IF temp<55C for period T=x min, overclock for one step
for example

I don't know that something like that is possible on the antminers. 

Works great on my SP20s tho.

new miner, my chains are 11 degrees apart in temp.

any solution to this? my other s5 is only 3-4 degrees apart.

im going to worry about it because this s5 keeps dropping its hashrate. its at 570 gh/s right now...

i updated the firmware. still doing it. and now the chain that showed 51c before (chain2) is showing 30c temp.
