1281  Economy / Computer hardware / Re: PCI-E cables with 16AWG wires and tinned ends - great for server PSU mods on: December 04, 2014, 03:22:54 AM
Any chance of you getting 8 pin cables?

I dont see much point in an 8pin cable - no ASIC hardware uses them, and most GPUs use only 6pin anyhow. The extra 2 pins are both black GND wires and AFAIK the GPUs with 8pin sockets will run fine with only a 6pin cable
The poster was no doubt referring to the 8-pin EPS +12v cables used on A1/A2 miners based on Innosilicon's boards eg. 'Dragons'.

They are designed for supplemental power to CPU's with 4 +12v and 4 returns. http://www.moddiy.com/pages/Power-Supply-Connectors-%26-Pinouts.html

Those are not the 6+2 PCIe GPU variants with the 2 extra returns in them.

And yes, I'd be interested in a few of them as well...

Ah - I suppose these could be made, but theres two issues:
1) cost will be about 30% higher (33% more wire, connector, and weight)
2) I really need a 100MOQ to create new cables. If anyone is interested in putting some deposit on at least 50 i could have them made, but from what ive seen the great majority of equipment is powered by PCIe.

Given AM's disasters with their chip/Prisma/Tube, let's hope they put in the winning bid at the HashFast IP auction tomorrow.

As a direct and indirect shareholder, I would hate to see KnC/BitFury/Cointerra beat them to 4th gen 16nm FinFET ASICS, especially when they have to opportunity to catch up by simply buying HF's GN2 design at a discount.


That would be a crazy twist of events.   It's not going to happen, I think we both know that...

I'm interested. Why don't you think it will happen? You never know...  Wink

why buy someone else's IP?

The story given by asicminer was that the current gen of chips effectively came in at half of expectations, but for a reason they identified - presumably the next gen will be the same architecture but at the previously-promised ~0.4w/GH

They are doing business right in term of everything I can control. I agree video of hardware, bills, address linked to a pool would help Wink

The option 2/ you give is reasonable, cloudminr said they will implement fees down the line. They want to grow and to grow you have to invest which is what they are doing.

again though - theres zero explanation of what fees and when. There's nothing stopping them from saying that fees are $5/TH/day, starting next week. It would make the cloudmining contract worthless within the next 2-3 months, and you would have no option but to forfeit your hashrate and accept major loss because their fees are equal to $0.30/kwh.

There is a legitimate market for cloudmining, but it can't be based solely on forum reviews and a fancy website. Proof that they own machines, are actually hashing to an address that is the source of dividend payments, photos of the equipment/location - all these would help demonstrate that this is more than an obvious ponzi scheme ("buy this, we'll give you THIS slowly over several months/years, there's zero strings attached") and that the people running this at least have hardware.

----> and, even then, there is the risk that things become unprofitable. zero fees cannot exist forever - if they start taking losses they will implement fees or dissappear with the equipment.

1285  Economy / Service Announcements / Re: [ANN] CLOUDMINR.IO Mining contracts || 0.0013 BTC / GHS on: December 03, 2014, 10:37:13 PM
Are there any pictures of the mine?

I find it hard to understand how this isn't an obvious ponzi scheme.

Hashrate is 1.1btc/th (-9% to vip users with referals), and even the most conservative estimates (5c/kwh, 0.5w/gh, zero overhead) indicates that there are at least $180/year in costs. A more realistic estimate (0.7w/gh, 7c/kwh, minimal overhead) put costs at over $365/year.

Unless fees are implemented out of the blue to recoup these costs, this makes no sense.

I think they said pictures of the mine should arrive.

They could have a really good deal on hardware and they may be ready to invest some money in the beginning to become bigger; when they got big enough they will ask for some maintenance fees at least for new contracts.

I think it would be great to have the pictures. I definitely understand the amount spent to promote the site
and its a great strategy. i invested a small amount in the beginning, and is have already got around 20-25% return.
i agree with this pictures are a good thing for alot of people. Would preffer a video even if it is like 30 seconds of quick walkthrough showing miners and all that good stuff i am sure that will make people happy. Also people are always happy to see live miner stats from cloud mining and also allow people to plug in own miners like ghash.io allows people to do and still cloud mine off cex cloud shares  Cool

Not just a good thing - it should be mandatory. Even then, these forums have seen dozens of ponzi schemes and cut/run scams in the past year. One that sticks out was a guy that sold hosted miners (s1 I think) with photos of his room with 16+ units. After selling the hosted rights for most of them, be disappeared. Never came back.

Things that seem too good often are. Be cautious about paying 100% upfront for something you don't have visual proof of or control over. Just because you're getting trickle payments doesn't mean you'll still be getting them next week/month/year. It's pretty much the exact definition of a ponzi

Cloudminr has been acting very professionally, paying on time and they have great support. They have used escrow for their signature campaign and offer attractive rates and no maintenance fees which guarantees ROI.

All this is why a lot of trusted members of the forum have trust them and bought GHS with them. Everyone should study and have its own criteria to invest.

If you wait for a company to be more established and if you are more careful, you have less chance of losing your investment but the earliest investors will get the most profit.

I have no idea what about the above statement makes cloudminer.io any less likely to be a ponzi scheme. There are only two realistic scenarios:

1) these guys are taking massive losses in the first year because they do not charge any fees. 1BTC invested and at least 90% of that cost goes directly into the cost of hardware. There will have about a 1.1BTC payout in the first year, and these guys will take a $200+ loss because there are no fees. The next year the investor would get 0.4BTC (approx) and these guys are still down another $200+. They would be bleeding money. That leads to the second scenario

2) maintenance costs will be implemented suddenly and unexpectedly. There is no money being made if they actually run hardware with no costs to cover power expenses. They will undoubtedly implement fees sooner than later. will that be $50/TH/month or $200/TH/month? Its not even hinted at. When these fees are implemented - your only options will be to pay them or surrender your hashrate to them.

OPTION 3) Give me $100 today, and I'll give you $1 every day for 110 days. Thats a 10% return in just over 3 months!
20 people sign up in the first day - I have $2000 on hand. I pay out regularly, $1/person/day for several weeks. after 100 days I have paid out all the dollars, but now have 50 more people signed up because the first guys are reporting that they got full payment back. Thats $5000 in my pocket, enough to continue the charade for another 2 months and pay back the second group on 50 people over 90% of what tey invested - and it seems like this is totally legit, so more people sign up.  Soon I have $50,000 in my pocket, but will have to pay out over $80,000 in debt over the next 100 days. I delete my website and disappear.

anyone running these in series or sharing radiators? I am wondering if I could run 3 C1 units on a loop consiting of 2 pumps and 2 radiators. This would provide redundancy in case of failure and it seems that 1 radiator is more than sufficient per C1
1287  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: December 03, 2014, 09:31:22 PM
I think someone needs to learn the difference between 4 Rails and 4 Connectors. Before they melt down a shiny new miner and blame it on the manufacturer.

This is why these manufactures need to be providing power supplies. I've never gotten the point of not providing one. Other than to make it difficult to figure out what the hell you're doing.

They could have an option to sell a power supply as an addon item. However, unless it's a well tested and known brand (if not built in house), you can get fires and potential law suits as we've already seen from bitmaintech.

why is it difficult to look at a guide for the product to see the reccomended PSU wattage (Generally a 650W+ is recommended for an antminer S3+)? Its pretty common sense on how to wire up a few PCIe cables and understand that a GOLD/PLATINUM ATX supply with a single 12V rail and sufficient wattage is required.

It makes no sense to buy a PSU (lets say a $60 Corsair CS650M) thats located in china, pay to ship it to your country (~$25), pay import costs ($10), and quite possibly not even receive a compatible power cable for your country with it. So now a PSU that costs $60 locally is received days later for $95+       why does that make any sense?

if you dont want to set up a powersupply, buy a complete solution miner like the S4 or the SP31

Plenty of cables still in stock- these are perfect for running sp20 units, which can demand over 250w per pcie cable

^because no fees and 1.1btc/th seems legit.... oh and a 5yr contract.

1th of equipment will use at MINIMUM 12kwh/day, or about $0.50/day if located in the cheapest power areas of Washington state with zero overhead. That's $180/year. More realistic variables are 2-4x that.

Beware the cloud ponzi
1292  Bitcoin / Mining speculation / Re: Nov 18th to Dec 1 diff thread (-0.35%) to (1.14%) on: December 02, 2014, 09:42:06 PM
So about -0.35% unless 100PH was added right this minute. I'm pretty damn happy about this, considering most of my profitability calculations made 3-6 months ago were assuming 4-7% jumps at this point in time.

I think the next jump may be fairly big though with the influx of the black Friday deals by bitmain and spondoolies. it's likely that each company sold 5-10 PH during that sale

well I grabbed 3x  sp20's that will be about 4th underclocked and about 2190 watts

I know that at least 1000 s-3's and s-4's sold I could figure the exact number looking at btc addresses.



I know at least 2000 btc was sent to spondoolies  addresses that is 1000 sp20's.  I looked at this address


https://blockchain.info/address/15QTGigFgnMpqcg5tQwBszQ94me98ZTVkr      and  some others .

 So to think 10ph will add in the dec 2 - dec 14 diff period is reasonable.  but 10ph is now 1/30 of the network so that is 3% jump.  My hope is under 5/6% for the next jump.
10ph is from spondoolies alone. Its likely bitmain had similar sales on the s4, and that knc/bitfury may both be incrementally adding to thier private mines also.

Nevertheless, it's safe to call this as a negative jump *party*

new firmware update posted today one of the changes is increased voltage to 760 This is the fix you all are looking for so I suggest anyone with flaky performance on there C1's do this update. I pushed my voltage up to match the new update and my miner is running even better then it was a 745 volts

It's worth noting that this will increase your w/gh power draw

1296  Bitcoin / Hardware / Re: ANTMINER S4 Black Friday Deals 0.409USD/GH/s, FREE International Shipping on: December 02, 2014, 05:48:37 PM

Has anyone tried the 100 or 125 MHz clock settings provided by Bitmain?  I'm just looking for feedback if everything is working properly, and if the power from the wall is as advertised?  Is there any risk from underclocking?

I'm also curious about the 200Mhz with the lower voltage setting.  If the lower voltage gets the same GH/s while using less electricity, then why not make it the default?  Thoughts?  Any response from Bitmain?



I would like to have a couple S4's using just under 1000W each at the wall.  I'm trying to run 2x S4's on a single 20A 120V circuit (temporarily), so I don't want them exceeding 2000W aggregate. Does anyone have recommended settings to achieve this?   I'm guessing the MHz should be around 160.  What is the formula for determining what voltage to use based on MHz setting?   It's like one of those IQ tests and unfortunately I can't figure this one out.  Burn on me.... lol


You could probably get a frequency code from the s3 thread that would apply to the s4.

My guess is 160-170mhz at 0.65-0.67v would achieve that

Could save some electricity charge if the power supply fancy LED lights are kept off.

All those LED lights spend less than a 1% of electricity involved, in fact real number is probably even < 0.1%. Next to nothing would be gained by turning them off.

I prefer LED turned off as each LED is about 1 watt and the total farm would take 20-30 watts which is still a burden when it come to ROI...

Seriously? 20w is maybe $2/month- definitely not breaking the bank, and looms pretty.

Most led power supplies do have a switch for the lights though

spondoolies sp20's have been shipping the bitmaintech coupons had to help sell the s-4's.  So 1 or 2% jump looks pretty sure right now.

I purchased 2 sp20's and kind of want to get one more. I know I am not the only one doing this.

I expanded aswell.  With winter weather hard to pass up cheap/free cooling.   

It will be the big centers that really give us a jump.   I thought they would wait till next gen, but the SP gear appears to have quite the lifespan with it's underclock. Guess time will tell.

even so, its virtually impossible to see 15%+ jumps happen many more times without an increase in BTC value. Its infeasible for people to routinely add that much to thier farms without rapidly hitting thermal or power limits and needing to rely on cloudmining or find a dedicated location. I think we will see
+0.2% this increase
+10% next
+6% after
+ 2% after, followed by a few more small increases unless hardware prices or bitcoin value changes

Use something better
