please I still have nightmares about the genesis-hashlets-nicehash-westhash incident.

All because of the switch from cex.io to mmpool.org

I never want to find out a million dollar problem again.

nice do you use freq 240?

I did not pass any parameters, so yes, I think the default is 240.

After about 12 hours I'm averaging this nice number:

(avg):1.444Th/s

And I found a BLOCK! Grin

Probably not bitcoin though Sad

and it's not mine (pun intended) anyway - rented out.

A flat rate 100 posts. Senior members and up.

Tier it :
Senior .... 0.1
Hero ....... 0.11
Legendary .... 0.12

Right now I am rent my sig for .2 btc a month 200 posts. So far I did 280 will end up doing 350 or so.

But I am retired and in my 50's. I have spare time and don't mind shooting some b.s. on a net forum.

Been on forums since 1997. I must have 50000 posts scattered around on :

anandtech
macrumors
123macmini
parts express tech talk
hashtalk
bitcointalk

are my bigger forums. So to me a few bucks a month say .1 or .2 btc is nice .

It needs to be a flat rate. putting in jr makes too many. I made the jumps close so the senior guys don't fell left out.

if you want put in a full member but make his much lower 100 posts and .05 this helps cut down the list.

Well I don't know why I didn't think of that, even after seeing the image of the one above taken apart. God damn fan controller!!! I just went and got one and yes it does help quiet it down some. I am ordering some extra fans for the push pull effect and with the controller the sound should be manageable now.

just so you don't overheat please drop freq down until you get the second fan.

try 230 or 220.

somewhere on the short tube thread there are photo of burnt out tubes.

we basically turned the handles out and did 2 fans for anyone of us that did this temps went down. and the % of good hash got close to 98-101

good info on freqs for the short tubes below

So you mean something like this:

This is before the Firmware update ... Now it's not that different

perfect thank you.

try using freq 212.5 see if you get the hw to drop. you are correct those numbers suck. I have had my hand s on 20 s-3's I have had 3 dog's so to speak nothing made them better above 212.5, but all 3 of them ran decently with freq 212.50 or freq 206.25

@aclass

Reduce frequency or possibly change PSU.

How high is too high?

S3 with latest FW
High as in the ballpark of accepted high.(currently 101 HW and 206 Accepted) Not an OC issue as its high at that level as well. Tried to UC with the same result. Temps are at 35 and 39.

I'll try with another PSU tomorrow but this one is a 1200W gold with all 4 sockets full on the S3

You wasting time as your description is not adequate please show a screen shot like this. If you can't do a screen shot. list all this info

I have a couple of extra Dell 750psu's with breakout boards and cables (from sidehack). They are loud but no louder than the Prisma. 2 of them will power 1 Prisma easy with all 8 cables.

I've polluted this thread enough so if interested please PM me .

.33BTC for 2 of them. PSUs, Boards and Cables

EDIT: Hey Phillipma1957 which fan is that and did it slow down the original at all or does still stay ramped up?

that is a great fan 140 mm made to fit 120 mm quiet but it did not make the stock fan slower.

I wire the stock fan to a fan controller that fixed noise.

link for fan

http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

Many times I pull one s-3 stock fan and add this works well for that too.

At one site I have two tubes running "broken down". What I did is detach the hashing modules from each other and install standoffs on the board side. They sit flat.

Then I attached one 120mm fan to each one. They stay at about 40c and 99.5% of expected performance. Also super quiet as the fans are running off of 5vdc!

The disadvantage is they take up more space this way. Tongue

I'm interested to see the design--can you post a pic if we ask nicely?

yeah . I would like to see it.

also at crazyguy a 1 board piece could be a good seller.

sell the board
the heat sink
the thermal pad
adapter plug
sd image card

I would buy that .

It should do 325-375gh

use 250-300 watts.

could be made to be very quiet with fans.

Thanks CrazyGuy, I now have 4 prismas connected to one BE cube that is chugging away the past 2 hours now without problems. I needed the dip switch info for sure. Straight forward install, everything there and even a few extra cables. Sweet more stuff for the parts drawer.

Apologies for the dark pic. But you can see I am powering 4 prismas using two stacked 2000watt IBM DPS2000BB power supplies with Sidehack's awesome breakout board and his cables 1 PCI-E per hashing board (which I admit are a little long for this layout). Cables are not hot or warmer than outside environment. I had a little mishap that involved grounding metal to some parts of a hashing board with pops and sparks but that board is chugging away anyhow Grin

The tubes do give off a lot of heat, more than the S3 for sure, but just a bit more than a S1. Most of the heat is coming from the stacked power supplies pushing ~4500watts combined. (not confirmed soon I will obtain some recycled PDU's that meter each outlet Cool

) I used the two fans that came with my older S2 kit for the power supplies, one to push, one to pull. One just one wasn't enough it would overheat and shut off.

Pool side reporting 5.7Ths past 1hour, difficulty at 4096.

try setting them to freq 230. I did extensive testing and used the short tubes for about a month.

your numbers show me that you are running too hot. and maybe under powered. you can tell by your

Real Performance: 5482.83GHS vs Expected Performance: 5898.24GHS

92.96%

If you have enough power and are cool enough you run at 98 to 101%.

here I am overclocked with 2 short tubes. but I used 2 fans and had robust power supply overclock was 280 vs 270 stock

here is a 290 clock. using two fans and handles out not in

second fan added handles out. handles out takes heat further away from the chips. no question 2 fans and handles out helps units to be cooler.

Hey Phil, the link you have for the wire is 12 gauge 10 feet long. You said its 10 gauge and it really drops the watts. Just wondering if you used the 12 gauge in your link or if you used 10 gauge. I found 12/3 @ 25 feet for 27-28 bucks http://www.homedepot.com/p/Cerrowire-25-ft-12-Gauge-SJOOW-Rubber-Cord-Black-282-3603A/202564772?N=5yc1vZc57q or you can grab 15 feet of it from amazon if you have prime for 19 bucks here http://www.amazon.com/Coleman-Cable-25-Amp-12-Gauge-15-Feet/dp/B002G9TNFG I am just wondering what you use 10 or 12 before I order it. Also does anyone have these running on a RPI yet? I have the B+ model or should I go out and grab the old B model or just order the BE controller from crazy for .069 btc? Also just curious if its working with the latest minera image or is there a custom one to get them going. Thanks all

stupid mistake

here is my 10/3 link

http://www.ebay.com/itm/25ft-power-cable-wire-10-3-600v-30-amp-STROW-generator-power-cable-/261536109031?pt=LH_DefaultDomain_0&hash=item3ce4c451e7

good four 4 six foot cables

now I am currently using the first ebay link which is 12 awg and 10 feet long.

I dropped my power from 1070 with a 14/3 cable
to 1009 with a 25 foot 12/3 cable
to 988 with the 10 foot 12/3 cable which I thought was 10/3
I ordered a 25 foot piece of the 10/3 and will make a 6 foot cable.

So the 12 awg is good enough for the 1 evga 1300 psu or in my case 1 1200 watt seasonic platinum.

both the seasonic and the evga stock cables are 14/3 and they run warm.

I will post 10/3 cable results very soon.

what is your power cost?

how loud can you stand the miner to be?

yep and all the big boys need to do is stand pat and do their best to limit network growth under 3%.

I think you're trying to talk them into something that's good for you, but bad for them.

not really as I do not mine much any more I buy coins.

today coins dropped to about 350.

they (the big 5 or big 6 asic builders) take on big risks by large build outs. build a 20mw farm running 30ph in 45 days like bitfury did in august.

then have coins drop to 200 usd. big risk.

slowly switch out your older gear at .8 or 1 watt with .6 or less newer gear. Then sell the older gear to miners call it a c-1 or a s-4 instead of s-3. This repackaging is being done right now by bitmaintech overcharge just a little so it slows the pace and let that pay for the newer build. win for the builders at almost no risk.

BTW either way is bad for the home miner.

There is No need for fast expansion for the builders. 2 exceptions would be finding a .1 watt a gh method or big rise in btc price.

i have a bad feeling about manufacters of hardware mining against there customers. when btc gets bigtime, i see some type of regulation on these company's, i hate regulation but these companys are out of control. greedy people that never gave a fuk about btc will destroy btc ,thats if we dont counterattack these fukers. i am not smart enough to take this conversation any further, anyone else?

Its a free market, i'm sick of ppl asking for regulation while completely miss the root of the cause.

You will never can regulate this effectively even you have the law written up.

ppl will buy miner because they think there is money to be made. Simple as that.

I would say, smart ppl would take the risk more carefully.

The key is multiple strategies.
I can't beat a 3 or 4 cent a kwatt miner with 5ph purchased at 200 bucks a th. So I stopped trying to do that. Still money to be made legally . I found a second house with full electric no heat pump style heat in the senior housing area of the villages. located here in NJ. They use baseboard electric heat which means well tuned s-3's are a godsend for them. He is an ex programer of cobol and is still tech savvy enough that I trust him to run the gear. So basically if this works out I may end up having him running these in 10 to 20 homes.

Key is to have seniors with brains that will go with the idea. I will use him as a test.

Quote from: mrpark on October 23, 2014, 10:27:36 PM

That extension says 15 amps, that is probably the max. So continuous load perhaps 12 amps.

it is 10/3 gauge 10 feet long. It does really drop the watts. the stock cord in a evga 1300 is 14/3. if you go the route of cutting it into a 2 foot 1 plug extension cord and an 8 foot psu cord you won't be able to overload it with an evga 1300.

I could test the cord to see if it does more then the 1875 watt rating but since my loads on it will be 990-1250 I don't bother.

Hi Phil,
I was wondering if you had a link to where you get the good 10 gauge PSU cables? Where I get them is way over priced.
Thanks again and keep up the great work I like you posts on different miners.

yes you have to build them but this is what I do.

I buy this:

http://www.ebay.com/itm/221564715692?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

this

http://www.ebay.com/itm/360886445299?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

and this

http://www.ebay.com/itm/LEVITON-515PR-NEMA-5-15P-Commercial-Grade-Straight-Blade-Plug-15-Amps-125-V-/221574124234?pt=LH_DefaultDomain_0&hash=item3396d8d2ca

i then make 3 x psu cords and 3 x short extension cords

total is about 60 bucks. for 3 of each

you could buy the 10 foot 10 gauge extension cord above for 11 and add this

http://www.ebay.com/itm/Hosa-Technology-PWA-421-Power-Adaptor-IEC-C13-to-NEMA-5-15P-Cable-PWA421-/251674171871?pt=US_Cables_Snakes_Interconnects&hash=item3a98f319df

I have yet to try that should work.

the key to either is those 10 foot extension cords from zorro. 11 bucks is very cheap

was on a different pc without access. but these 10 avg extension cords help power my 1200 watt plat seasonic drops from 1070 watts with a 14/3 c13 1 piece cable to 1007 with a 12/3 c13 1 piece cable to 988 watts with a 10/3 1 piece cable.

so that is 82 watts = 2 k-watts a day .. I can't afford that my power is 16 cents. so this saves me 32 cents a day running 3 s-3's

BTC mining is but 1 slice of the world of BTC.

I live in a so called first world stable country the USA.

I do read my history and in the period of time of 1857 to 1870 the USA was a mess. Most countries have very unstable times sooner or later. Having 50 or 100 BTC stashed in cyberspace is a good hedge for instability of many kinds.

Here is a very small list of countries having tough times today.

Egypt
Iraq
Ukraine

here is a wiki list

http://en.wikipedia.org/wiki/List_of_coups_d%27%C3%A9tat_and_coup_attempts

33 in the 2000-2009 time period some happened some did not.

http://en.wikipedia.org/wiki/List_of_coups_d%27%C3%A9tat_and_coup_attempts_since_2010

and from 2010 to now

23 more were tried some worked some failed. . trust me having a stash in cyberspace is not so bad of an idea.

I will mine a bit but I am buying coins more then anything else.

Quote from: SquallLeonhart on October 22, 2014, 07:36:42 AM

You need at least 1 PH to solo mine, anything lower then that is like gambling..

could you tell us why? the truth is solo mining is a very high risk very high yield investment

If you have 15 cent power or better and the gear burns .8gh a watt or less.

Gambling is putting in money at unfavorable odds.

Investing is putting money at favorable odds.

If I offer 1200 to one on a 3 digit number and you take me up on it you are investing in a very high risk high yield investment.

If I offer 990 to one on a 3 digit number and you take me up on it you are gambling.

The true odds are 1 /1000.

So if I go to nicehash and buy 500th for .012 a th and spend 6btc I am investing.

If I go to nicehash and buy 500th for .016 a th I am gambling.

first case the math is in my favor.
second case the math is against me.

Back to the OP this is all simple game theory. No more no less.

Thread locked look for a new one soon!!

running from 0.033% to 1.16%

I still see no reason for builders to push for more data centers

With current coinbase price at $363 usd a coin

building bigger data centers have big downsides. 1 good price drop under 200 and the big guy will be seriously set back.

I wonder how long we stay at 300-400 btc price

because at that price growth will be very low.

I am certainly going to buy a prisma. I am trying to decide which group buy to go with, this one or Canary's. What is the deciding factor for me is when I will receive it.

When, if I order today (10.23.2014), do you estimate I would receive it? Would it still be within October?

Thanks!

ASICMINER has informed me that there will not be an inventory shortage after the 27th. Batch 6 order will be placed on Sunday or once we reach 10 units sold. I will also have units available for immediate purchase on ASICPuppy.net very soon.

I want to buy on asicPuppy.net please let me know when. I will need the sd card and run it on the rasp Pi you sold me a while back.

I will post a shit load of photos and tips. including a demo on how your psu's power cord matters for power use.

hint a 10gauge psu power cord does amazing watts reduction.

Quote from: unknown.usr on October 23, 2014, 01:29:47 PM

Will there be any mining? Are there devices coming? Or is this a lost cause?

my advice is get a refund. something back is better then nothing back. and unlike so many bad companies they have stuck around and refunded a lot back. I would get a refund if I were you.

I just hooked up the 2nd one using phillipma1957's suggestion so far so good but it's only been about 20 mins. The cables don't feel warm as of yet.

It should be good.

if you have a k-watt meter check watts should be 1020-1100 watts.

if you can post a photo to show the hook up please do.

It seems OK none of the connectors are warm at all. The wires are a little warm (barely) but not like before when I was just using 4 cables. The bottom/left share one of the double cables and the top/right share the other. The short cable between the 2 connectors isn't warm at all.
I'll keep a close eye the next few days. No meter sorry. I need to get one now that you mention it maybe I'll get one tomorrow. Any recommendations.

this model is pretty good. I have found that k-watt meters do not like to run 24/7/365 if they are over 1200 watts

I have also found the evga 1300 can do about 1215 watts at 24/7/365 well I ran one for 70 days pulling 1215-1220 watts.

look for a better price but 20 bucks is decent
