Seems like an Awakening of something big. http://iotaexchange.com/ are now closed bitcoin and iota deposits. Prepare for many exchanges provide this token to trade. I have regret to not buy iota earlier, and when it hit global exchange the price will create more regret. you can still buy otc via slack |

Where can i buy IOTA right now? Which is the cheapest way?
there's only one way atm http://iotaexchange.com/when you wait a week you can buy it on many exchanges (bitfinex f.e.) from OTC on slack, ioexchange.com already closed iota deposit |

will the token be available on the market such Poloniex after the ICO?

are you pool mining all these gpu's?
yup i don't have time to self manage and update eth wallet, downloading blockchain, etc |

 these cable are my enermax PSU's molex (PSU's endpoint) , ran 2 riser for each cable  if I use 2x Molex to PCIe converter to powerup PCIE 6 pin riser  never use molex to sata converter |

This is so much great information that I had no idea about. Thank you so much, very informative and important! In other words, you're saying that 6-pin connectors on the risers are needed. However, if that's the case, then how come it seems that most miners (well, that I've read about, perhaps not "big-time miners" though, but they do just fine with molex on their risers. Most cards use more power than the Pulse Mini. Of course, under volting is an option that many do so that would explain it. these problem started when AMD launched RX series GPU with only 6 pin powered and use up to 75w on the peak from pcie slot i've been mining since HD5xx series, into HD7xxx and R9... there are no case of riser power cable melted, because those early gpu mostly use power only from GPU's power connector, and only little bit from PCIE slot Let's say the card uses 150W and since it's being powered by 6-pin cables, it also draw 75W from the PCI slot. Obviously that's not a good idea for molex cables then. However, if I under volt each card to make sure it never goes above 125W (lower of course to have some head room), it should be fine until the new 6-pin risers arrive, correct?
For example, if I under volt it enough to get to 110W max, would it still draw 75W from the 6-pin cable and then another 35W from the molex cable?
Thank you again for all your answers, you're extremely helpful!
each gpu have different circuitry, bios and driver some GPU split between GPU Core power (from GPU pcie connector) and GPU Memory Power (from PCIE Slot), some use shared power, by undervolting surely it help but gpu has their own allocation of power which i am not sure, that's why i will just take the safest option by using pcie powered riser Edit: Are you sure I can't use two molex risers on a single cable? Most people I've read about claim that it works just fine but that three is too many.
no i am not saying you can't, but it safer to use pcie power, I personally had use 3 riser in single molex which is ended up in PSU connector melted (the riser connector end was just fine), then I use 2 riser for single molex which most of the time just running fine, but some rig melted at some time when the room is hot enough, but until now i never had issue of melted connector when using pcie powered riser |

Thanks for clarification. What if I use a power cable joiner? Will that help with the single ground?
Currently both PSUs are plugged into the same surge protector.
Eventually they will be on the same PDU once I get that installed.
i don't have that deep knowledge of internal circuitry of PSU, what i did and assume is just to get into safest first than into the unknown so i will just make (riser+gpu) on same PSU because i know that riser power and gpu power are somewhat connected inside gpu, unlike on [ gpu <-> riser <-> motherboard ] connection, gpu and motherboard are power disconnected because when i see the riser pin trace it bypass the power pin from motherboard, and use their own power from molex/6-pin instead of from motherboard pcie slot and also i have an experience on earliest day of gpu mining, when there are no powered riser available, i use different PSU for GPU and motherboard, and of course GPU are slotted directly into the motherboard since at that time there are no so called "gpu riser for mining", and then the motherboard just explode, taking that experience i never split PSU between power connected devices |

electricity here is 16 cents. Is that really bad. All I really want to do is break even and have fun.
you will have a fun when it break even, so pick your priority to break even first |

The PSU I've purchased has six dedicated cables for the GPU's, so if I can use each cable for one GPU and one riser, then it's all good and I'll go with that.
If that's not recommended, then I'll have to use the molex's but the PSU only has two dedicated molex cables. So with six risers, I'd need an extra molex cable. Question is if I can plug it into the connector in the PSU that's supposed to be for SATA cables - and if I can take that molex cable from another PSU (same model but lower watt)?
if you want to use multiple PSU,, you shouldn't mix 1 PSU for riser and another for GPU. GPU+Riser should be powered by same PSU, as there are electrical power connection between PCIE power socket on GPU and PCIE slot in Riser. Power connector on riser is not to power up riser, it is to power up gpu via pcie-slot 1x connector which spec is allow gpu to take up to 72w from these pcie 1x slot, so sata powered riser is should not be allowed splitting multiple psu between gpu and mothherboard is fine, splitting multiple psu between (gpu+riser) and another (gpu+riser) is fine too I have been using one PSU to power the risers and one PSU to power the GPU for all my mining machines. Never had a problem. I use one of these to power the cards: https://www.newegg.com/Product/Product.aspx?Item=9SIA7GT5NK5071And then a 600-700w to power the motherboard, SSD, and risers. Would that normally cause a problem? on most case it wont be a problem, as long as both PSU are connected to same ground wire, since both PSU ground ended up on the same home power plug it will be on the same earth ground, but on some case, there are different circuitry between two kind of PSU which make their ground is not equal or some other cause, then some problem |

yes you can, personally i have EVGA GQ series exactly like that, and done cable test using multimeter
if G2 and GQ are same then you can put sata/molex to that connector like i did, but i never had G2
That's great news if it's possible! This also means that I should buy risers with molex connectors, I assume? That way I don't need to buy extra 6-pin splitters. Or is 6-pin splitters and use them still better than using molex cables? one dedicated molex cable for one riser is safe, but never use single cable for multiple riser in daisy chain but personally i prefer to use 6-pin powered riser, not just because its safer, but molex powered riser are using 1x 12v (yellow) and 1x 5v (red) rail. while pcie riser use 3x 12v (yellow) rail most psu has limited 5v rail wattage, but huge 12v wattage (and mostly psu watt spec are for 12v rail, so 1000w psu means 1000w for 12v rail). if you ran out of 5v watt limit it could be problematic GPU use 12v and 5v to power up, most 12v are taken from GPU power connector, and 5v (and some tiny 12v) are taken from PCIE-1X slot on PCIE 6-pin powered riser it mising 5v pin, they convert 12v to 5v by using step down converter, highlighted in red box, so these riser only take 12v and convert some into 5v, so it does not use 5v rail from PSU, while Molex riser directly use 12v and 5v from PSU without any conversion  Edit: I should mention that I've purchased six Sappphire RX 570 Pulse Mini. According to Sapphire they're drawing less than 150W. If the 6-pin cable is rated for 150W then molex with another 50W should be more than enough for those GPU's, correct?
6-pin cable rated for 150w is actually not accurate, the story is initial pcie power cable is only 6-pin they rated it for 75w, but there's need to deliver more than 75w, so they changed the spec, pcie power should be rated 150w, to differentiate which cable can deliver 75w (older spec) or 150w they add 8-pin connector, which another 2 pin is not to deliver power, but only to signal GPU if these another 2 cables is connected it means the cable is on newer spec (150w), gpu can take up to 150w, but if only 6 pins are connected gpu only allowed to take 75w since the cable is assumed on older spec which is rated 75w both 75w and 150w connector deliver power through 3x 12v pins, so it doesn't matter 6-pin or 8-pin connector since both are using 3 pin to deliver power, what matter is the diameter of cable (which is rated in awg), 18-16 awg wire can be configured for 6-pin, 6+2pin or 8 pin, but 24-20awg only allowed to be configured as 6-pin, since 24 awg wire each can't deliver more than 25w of power most current PSU cable are using 18awg or 16awg, so it is safe to assume it can deliver up to 150w for 6-pin/8-pin connector now about that 570 pulse mini, if the gpu use 6-pin connector, then the gpu will only take 75w from gpu power connector, so if i assume that "less than 150w" words are meant to be "it never exceed 150w, but it can take up to 150w" then when it take 150w, gpu will take 75w from 6-pin connector on gpu, and another 75w from the riser, since molex are rated 50w, its an overcurrent for molex connector |

splitting multiple psu between gpu and mothherboard is fine, splitting multiple psu between (gpu+riser) and another (gpu+riser) is fine too
Sorry if I wasn't clear with my message. I'll try to explain what I meant better. The EVGA G2 1300 that I've purchased is modular and has two inputs for molex cables. Which means I could maybe run two risers per cable for a total of four risers. However, the PSU also has inputs that are meant for SATA cables. The connector looks the same. Could I take one of the molex cables that came with my other EVGA G2 750 that I don't use and plug it into one of the SATA connectors on the 1300 PSU? If you look at this image it might be clearer what I mean. The molex connectors are the ones called "PERF1" and "PERF2". To the left of those there are six connectors for SATA cables. Could I use another molex cable and plug it in to the SATA connectors instead? https://www.evga.com/products/images/gallery/120-G2-1300-XR_XL_5.jpgyes you can, personally i have EVGA GQ series exactly like that, and done cable test using multimeter if G2 and GQ are same then you can put sata/molex to that connector like i did, but i never had G2 |

it could be riser cable, or pcie slot on mobo is damage or even your gpu is damaged
hamster wheel rx470 is the cheapest rx470, they use lower quality component, if you want safe run, you need to run the fans at 100% all the time

newer driver works for both 4xx and 5xx so use new driver it will run both
then patch the driver so you can use bios mod

A fully modular PSU like Corsair RM1000i comes directly with 8 PCIE cables that can be made 6 or 8 pin and it can support up to 8 GPU-s , it also come with 12 Sata cable connectors enough to power up many risers. I think the PSU is the most delicate part choosing when building a mining rig. This PSU supports easily up to 6 cards of RX 480,tested by me as one card max power draw I see in GPU-z latest version is 133 watt.
RX480 is powered by 6-pin pcie power not 8-pin so it definitely take up to 75w from the connector (since 6-pin pcie is max 75w, 25w for each pin), if the gpu take 133w then there are 133-75 = 58w gpu take from PCIE slot 1X, i am sure it is only for peak consumption of short period of time, it its continuously like this then sata power connector will be burn because sata only limited to 35w power delivery so never use any sata power for gpu mining |

Hi,
I'm going to order 8 or so risers (will only use 6 GPU's but wanted two extra spares just in case) but I'm not quite sure what to pick. I've also got a question for you experienced miners regarding PSU cables for the risers. So here goes.
Should I order risers with 6-pin connectors? If so, can I power 1 GPU and 1 riser with the same cable from the PSU? If not, then the cables on the PSU won't be enough.
Or should I order risers with molex connectors? If so, can I power two risers with one cable from the PSU? Also, the EVGA G2 1300 that I've purchased only have two cables with molex, would it be possible to take another one from my EVGA G2 750 that I'm not using? I'm assuming it's the same cables. Can I plug the third molex cable (on the PSU side) into one of the ones that are supposed to be for the sata cables (there are only two peripheral slots on the PSU)?
Thank you!
most PSU these days have limited molex connector, and have a tons of sata connector and most sata cable will be burned out to flame on RX GPU, so there are no place for sata in mining rig to be safe since pcie 6-pin cables are limited, and even more limited molex, it still better to use pcie 6 pin cables since their spec is designed to deliver up to 150w (molex is only 50w, sata is only 35w) so the solution is just use PCIE 6-pin splitter, one end for riser, and another one for gpu, so each gpu+riser only use one cable from PSU Is this the cable? http://www.ebay.com/itm/18AWG-6-pin-to-2x-6-2-pin-6-pin-8-pin-Power-Splitter-Cable-PCIE-PCI-Express-/361651807884?hash=item543420a68c:g:eEYAAOSw0fhXjlMJyup that it is, only use pcie splitter that use at least 18 awg wire, 16 awg is better, but never use 20 or 24awg wire |

it is a fuel to run decentralized smart contract
Funny that you say that. How can a centralized platform/project fuel a decentralized smart contract? Ethereum is centralized, whether you like it or not. For OP, ETH is not a coin, it's a Token, there is a difference between the two. To be concise, a coin has its unique features and its own (original) blockchain like Bitcoin, but tokens, on the other hand, represent an asset (of a project/platform) on top of the blockchain, using another 'layer' of the blockchain like Ethereum. i am not trying to be political or very precise here, centralized or not, its a token to be used as a "fuel" to run smart contract on blockchain, as in to execute contract you need to give the miners these tokens, as a reward your contract will be executed and written to blockchain by miners if these contract that need to be executed is valuable, then the token that need to run this contract is valuable too, if it is valuable (even more if it is rare) then there will be a demand, if there are demand and supply there will be trade in this ecosystem, as a result the token will become currrency in this ecosystem so answering this But can it be used as currency? Will we ever see children buying ice cream cone using Ether out of their wallet like we imagine will happen with BTC? Or is it unlikely?
it depend, does the ice cream seller need/want to run a contract? if it is then the seller in demand of the token, the seller will be happy to accept ether, and the children will be happy to have an ether because they can trade it with icecream so in this condition of ecosystem, the ether does have a demand, have a supply, its valuable, it can be stored, it store a value, it is measurable, it can't be duplicated, it is transferable.. does it qualified to be a currency ? |
