Is the S5 string design safe and was it really tested properly?

[DevonMiner]

For what it is worth I think we will see SP and Bitmain continue to battle it out.

Yes, that is where the market is at the moment ... interesting times ... Bitmain celebrating 12 months ... Sponds yet to do that.

Today I bought 12 pieces Antminer S5

I trust them today more than SP20 , especially after seeing this picture. Because they have  4  PCI-E slot, For 600W.
SP20 has 4  PCI-E slot for 1200W (Max)

I have 3 x SP20 and
6pc SP20 purchased by December 17, to get my hands probably 29.12

I also have a 5pc KNC Neptune, with no burnt PCI-E slot.


The rest are all Bitmaintech production. (37x S3, 6x C1, 2x S4 )

It would be seen that picture before, then I would not have ordered more SP20.

THIS IS MY BAD
spondoolies is so kind that give me a new one just for free!!

next time use seasonic cable.

after the experience with mining ati r9 290 all this noname chinese shit PSU is simple shit. only premium PSU have adequate cable. I burn a lot of cable until I realized Seasonic PSU is, other PSU is Simpley lottery
When you baying seasonic cable check is seller official seasonic dealer,because lot  bad chinese copy is available.I do not understand how the noname Chinese think that if Avg 17 cable can haul 25A.

I made really good experiences with Antminers so far (except the big ones S2 and S4)

[raskul]

My main concern with the S5 is why does it cost so much?

The C1 is $325 and has FOUR hashing boards. The C1 boards also have a DC/DC converter for every two chips IIRC. The buck controller ICs probably cost more per unit than their custom silicon.

There is a major BOM cost reduction going to the chained design. The controller looks the same (cost reduced beaglebone black), the new chips of course have an NRE that needs to be recouped so they're probably just milking the first batch of people who are gonna buy it just because it's new.

Not even considering the possibility of instability or catastrophic failure due to the chain design, I'm gonna sit on my hands for a while. I'm willing to bet the first few price drops will be pretty good.

Who said they aren't losing $100s on the C1 at that price? You don't know.

I think them doing a batch 2 proves it.   But I don't have the info you do so I could be wrong.  I think they would have stopped after batch one, or stopped it completely like L1's.  

For what it is worth I think we will see SP and Bitmain continue to battle it out.

Batches are artificiality created as a marketing tactic.
For all we know the first batch might be few tens of S5 to test the product on live customers.

Thanks!
But shitty PSU that you said is come from CHINA surely, not from TAIWAN, we were all called as chinese but  there is a BIG difference between us.
I use super flower's PSU since I started mining, high C/P and realible!
90% load and no anyone fault so far

They were out of stock of C1's for a bit that makes me think they did run out to stop selling.  But again I could be wrong I have no proof either way.

I'm reserving judgement until i test my own unit.
I intend to draw a circle on the floor and surround it with candles to keep away evil spirits and unwanted outside influences.

Teehee 😜

Sp20  I have 8  they work great at 1500gh or under  If I owned the company I would have called them 1500gh miners
---
I clock my Sp20E at 1400gh or 1430gh max   I do not even attempt to think 1600 or 1700gh.
---

I agree. All buy, but no one sees that SP20 is still underperformed 1.7 TH/s ± 10%

Based on my 11x SP20 I only see 11 x  1.7 TH/s - 5%


Only my very first SP20 was 1720TH/s of normal room temperature. Even that only have one day to the first software updates.
I look forward to  software that would allow me back 1.7 TH/s +

get better cables  my SP20's are all perfectly capable of 1.7TH/s
i run them ~1.5.

[mavericklm]

take out the 288watt cap or the voltage limit of 0.790 and we can hit 1.8th/s

I have 11x EVGA G2 1300W

This is not about cables, but the software limit.

My second and third SP20 worked 1720GH/s and 1735GH/s  if they are accidentally have after update   SP10 software.

[Xian01]

What do you mean by "take out the 288watt cap" ? Blank out the field ? Set it to 0 ? Set it to a high number like 350 ?

[mavericklm]

You can't really punch something above 288, because the webgui puts back 288 in that field that you tried to put higher setting!
I did somehow, and don't remember how, put 1350w in there. But we still got the 0.79v limit...

I mean someone with programming knowledge, maybe even SPtech...
They don't give it out because they don't want higher rates of returning machines; and they still have them on stock plus another 3month after that....

Or maybe the settings are hard written inside and can't be taken out!

I had a 1600 EVGA which was only running one SP20... it went up in a puff of smoke... Sp20 is more about getting the settings right... I have three SP20 and each of them are able to go to 1.7TH/s

[mavericklm]

Did you burn the evga?

I did reach 1.7 too, with fan at 100%, max setings on voltage and wattage, and air at 0c.....

[BTCish]

So is it safe to oc S5 ?

I read here something else
https://bitcointalk.org/index.php?topic=920699.0

I have 2 x 750's on one SP20, 1 x AX1200i on another and 2 x 650's on another
all running ~1.4TH/s. settings on each:

Fan Speed 20
Start Voltage 0.69 / 0.69 / 0.69 / 0.69
Max Voltage 0.695
Max Watts 250 / 250 / 250 / 250

So is it safe to oc S5 ?

No. Only if you have a good fire alarm system and own guardian angel 24/7

S5 is in my opinion the fire hazard in this open air case.

sorry, my bad.. i meant it was the PSU which went up in smoke, when the S5 blew a hot-thingy-ma-jig. the SP20 is fine, no problems whatsoever. GUI's all returned no problem too, so we all good.
here is it now:

totally agree with that, i'm afraid.
