I'm only seeing about a 2x kick. It varies depending on the motor startup circuit, load, type of motor, etc.

 You'd have to SEE the wiring setup on this place to believe it though - the actual wire used is decent, the boxes and breakers are QO but the actual INSTALLATION is a massive code issue - I suspect the wiring was all done before code was adopted here.

 Ever seen an OUTDOOR breaker box on a house, using an INDOOR panel? At least that's the neighbor's box, and whoever installed it used silicone sealer around all of the openings, but GAH.....

 Overall, I'm most worried about the use of bloody spices (they DID use the insulated screw-on connector type stuff that USED to be valid under the code but does tend to have issues at times) and the breakers overheat-derating too much come summertime (but I'm planning to be OUT of here by then, and I'm VERY well aware of required derating for higher temps).


 I was, in the past, a union-trained Journeyman Electrician, bonded and licensed for a few years (in another state, but NEC is NEC). Code hasn't changed a TON since then, other than to adopt some "best practices" recommendation type stuff that is now required (like seperate ground wire, which was only a recommendation 'till the 1996 revision), but this stuff is scary in some ways.



i'm sorry the x3 was an allowance, i just got very used to it...like in using a transformer or AVR for motors a x3 is usually the rule of the thumb.

the panel box here are indoors, seen those outdoor stuff during my my days of researching. silicon sealant is wear and tear resistant, i bet that panel box would give-in to rust before that silicon sealant breaks or leaks.

so you are an electrician...i'm not, don't loose me on terminologies lol, don't know NEC and the Code. i do have electricity related minor subjects when in college, watched and learned from an electrician too...but i study and practice for personal use only, i even setup electrical cabling for my mom's boarding house and office (residential level only), my dad's farm, and a little electrical fixing on my friends homes.

in 1996 there it was recommended there to use a separate ground wire? here in 2016 we still have 2 wires a 240v and the other is the ground LOL.. i agree there is an element of being "scary" but the important thing is that i understand electricity and its behavior..i did a few live wire splicing in my lifetime in involving #10, #8 and #6 AWG..the sweat, adrenaline and concentration phew!

So I went and got Minergate Installed it on an aws Instance,and Started to mine DSH thinking it was the same thing as DASH. Now I have a bunch of DSH worth not even close to what it cost to run the aws instance.

i feel sorry for your confusion...but i would like to make it clear here, it was DASH (darkcoin) who copied or stole the name of DSH dashcoin.

Let me clarify, I will help people learn to do their own ROMs.  I am not looking to do 100 different ROMs, I don't have that kind of time.

As Eliovp has pointed out they aren't the easiest thing to do and take time to do correctly.  If someone wants to help themselves I will help them.
I am willing to learn how to my rigs using Hexeditor method. So far I had
3 full rigs of RX480 8GB ref
1 rigs of HIS IceQ RX480 8GB. Link: http://www.hisdigital.com/un/product2-933.shtml They had same heatsink design as XFX RX480 GTR. But not sure about pcb side.
2 rigs of XFX RX480 8Gb GTR.

All these cards using Samsung memory chip. So I guess they all had same timing right?
So far I manage to using Hex editor, locate the memory timing. I think i can replace the timing. But I dont expert enough to modify the VDDC for these. Willing to learn how to do it.

Thank you for sharing your knowledge to the community.

we have the same his iceq rx 480..i have a couple of those gpus..

i don't know about bios modding, but i'm looking into it... i just know how to flash bios to a  gpu.

how to solo mine this one with a gpu ?

to those who don't know how to mine to command line wallet (including me) just mine directly to your exchange wallet and wait for the gui wallet or until you know how to use the command line.

418 chunks  is not enough...should have increased the supply so we can run supernodes.. like now.

LOL there is a 3GH miner, let the small fishes get their coins first...well the buy support is huge at 1 sat  Grin


Hi what's total supply and how many premine and pow blocks ?

Coin Spec
Premine: 7 coins
Block Reward: The block reward is divided into two parts: a Miner Reward and an Airdrop Reward. The Miner Reward consists of 7 * ( n + 1 ) UR, where n is the number of newly signed up users whose identity has been certified within the current block by the Identity Authority.

I couldn't find a total supply, there might not be one.

Dev, the download links on UR homepage are broken.


1. Links are now fixed. Thanks for the heads-up
2. The total supply is based on the number of economic actors (humans) who prove their identities and choose to join the community... so it's not pre-determined. This is one of the major innovations of UR that helps solve deflationary or inflationary tendencies of other currencies.  See announcement above for more detail and https://ur.international/2016/10/17/how-does-the-ur-airdrop-work/ for more information.

gonna grab a few by mining so i wouldn't have to prove my identity  Cheesy

My cooler is supposed to be a 1/4 HP but it draws about 500 watts at high setting (actual measured figure, higher for a fractional second when the fan motor starts up), I suspect it's actually a 1/3 HP. Electric motors are usually highly efficient, but they are NOT 100% efficient (1 HP = appx 750 watts at 100% efficiency).

 If I was willing to run every circuit at 100% of breaker limit, I'd have enough power - but the house is old enough I'm actually targeting 75% to be safe, *AND* I have to worry about the total draw on the main breaker being the REAL hard limit here.


 I AM thinking about breaking down some of the parts out of my cooler and using them on my existing fans to make impromptu evaps, it would save noticeable power.
 I'm hoping to be out of this place before I actually NEED the evep though - 6 month lease and I figure that last couple weeks to a month of that for actually moving....




generally electric motors starting power is x3 when starting up, so if a motor is 500w expect 1500w starting power, gradually it will settle to 500w..

if you know your wire type like if its THHN or TW etc., you know the max ampacity of the wire, the weak points are the areas where the wires are cut and connected, i simply touch them and feel the temperature if it is heating up and i make sure everything is tightly connected. copper don't deteriorate, unless corroded by other elements.

for me 75 - 80% of the breaker limit is my target too..my breaker is 10 amps lower than my mains wire (max safe) ampacity though. well using 95-100% or maybe at least 90% of breaker limit will cook your breaker and you will experience occasional breaker trip.

2152  Alternate cryptocurrencies / Mining (Altcoins) / Re: What is the average life of a mining rig? on: October 20, 2016, 02:59:47 AM
I've already got my swamp cooler in the house, just not hooked up.

 Unfortunately, I'll have to shut down SOMETHING to power it when I need it.



 On a side note - I had quite a few of my DNet machines (the Distributed net client isn't mining as such, but puts very similar loads on a system for the same reasons) last ballpark 20 years before I finally retired most of the oldest ones when I moved this summer. The primary issue I ever had with those was FANS dying (and often causing overheat-related other dead parts), followed by motherboards dying.



you are really at the edge of your max safe power there..swamp cooler power consumption is only limited to the pump and the fans, well for my mining room i think the fan that blow air to the cards and and the exhaust fan is enough to move air around my mining room..

pumps that is 1/2 hp might be an overkill already to what i'm designing, and 1/2 hp is just ~ 400 watts. (240v here)

you might want to try my solution to my fans, this material can seal (with or without cover) where you pour the lubricant oil. my fans lasted more than half the summer here and still running 24/7

this is better compared to (3m double tape-the gray one, silicon sealant, other tapes) in sealing and work-ability of the material, purchased from an aircon/refrigeration shop. don't know the name of this, i just said the black sticky stuff..i just seen this being used by a technician for sealing holes where tubes had passes thru..these are very good at staying put and handling heat. in any case it is better to wash clean with alcohol the areas from oil and maybe a little bit of roughening the surface with a sand paper before sticking this material.

tip: use masking tape or re use the fan sticker and cover this black-sticky stuff after the work is done.



and i use this oil..

http://www.ariazone.com/product_oil_aa1.php

it is a bit expensive but this is just leftover so i'm saved from buying, there are other cheaper compressor oils out there and i believe they are better than standard motor oil.

OCminer has won 574 out of the last 1026 blocks which is 56%.  Will this change if Vorksholk comes out with the new miner?

Anyone know what is the cost of the type of computer OCminer is using or one that would win blocks?  Thanks

we should threaten to fork this guy off so he would be forced share his miner LOL (joke).
2154  Alternate cryptocurrencies / Mining (Altcoins) / Re: What is the average life of a mining rig? on: October 19, 2016, 12:25:05 PM
I ended up sticking some 60mm x 25mm Delta fans on my "fan died" HIS HD 7750 cards - they were left-over from CPU cooler days, I KNEW they blew plenty of air and had GOOD bearings.

 Turns out the cards run about 20c COOLER now, despite no shroud or any fancy mount directing the airflow - but they DID get quite a bit noisier.
 Thank goodness none of them were the 8000RPM screamers....


 The IceQ HD7870 has been a nice solid cool-running card, only issue with it is the fan sticks out so far it's a 2.5 space card.



 Don't get me started on reaching "max safe power limits" on my current place. Got everything traced out, and figured, and I'm going to have to shut down the A2 88Mh/s cause I don't have enough power for all 5 of my A2 units, and it's the lowest income generator I have left right now.




in your case you have maxed out your safe power limits..for me (and i believe there are others like me) it is the temperature that is maxing out..i think i can squeeze 10-20 amps more, my upgrade is gradual so every increase in amps i can observe everything needed to be looked at..this is the cooler part of the year but when summer comes, i think i have to shut down or under perform my cards to reach desired temps unless my swamp cooler (still being designed) is a success.
2155  Alternate cryptocurrencies / Mining (Altcoins) / Re: What is the average life of a mining rig? on: October 18, 2016, 05:01:28 AM
Got some 280x's still going for almost 3 years 24/7 temp 80 degrees 70% fan. Fans did stiffen up after about 2 years... I just spray some wd40 in them carefully when it happens and they are good as new again!

Ps. Wd40 is not recommended I belive machine oil is but... I've not had any problems so far... just made sure I didn't use too much so it would leak or get it on the gpu board.

WD is not good for high temperature operation. You need some grease like those used in the bike or car.

 Grease is too thick. Standard motor oil works pretty well though, and is designed to handle MUCH higher temperatures than any computer (in working condition) will ever see.

 On the other hand, any fan in bad enough shape to NEED to be relubricated isn't very long for this world as a working item. Relube is an EMERGENCY SHORT TERM measure intended to get you by 'till you can REPLACE the bad fan with a good new fan.

 Avoid sleeve bearing fans (this SPECIFICALLY includes stuff like "rifle" "hydro" "permalube" etc) - they do NOT live up to their claimed MTBF due to failure in the seals intended to keep the lube in, and VERY rarely last even a year in 24/7 high-temp environments.
 Stick with ball bearing - which can run for YEARS with no lube at all if you keep the dust and grime out of the bearings.

 This is why I generally stick with Sapphire or Gigabyte cards - they come with Ball Bearing fans across the board AFAIK.
 (Might be true for some other brands, definitely NOT true for HIS).




compressor oil is better, the oil that is used in car aircon compressor, it is not as thick as motor oil. got my 280x's with 90mm high speed fans zip tied to them..those fans are lubed with compressor oil, and i sealed them with a black sticky tar/asphalt like stuff i bought at an aircon/refrigeration shop..those fans are doing really well, summer has passed and they have not given up and no oil leaks.

regarding HIS, i just bought a couple of this RX 480 IceQ X2 Roaring OC 8GB, didn't know about their fans being inferior, got samsung memory though.

 THe HIS Ice-Q models with a blower are ball bearing and tend to last.
 HIS has a bad habit of using sleeve bearing fans on non-blower models though from what little I've seen of them - might depend on the specific model though.


i'm thinking if the fans failed  before the 2 year warranty ends, we can get the gpu replaced  Grin ,the problem with the blower type for me is the way it is designed, you cannot easily replace the fan if it failed..the non-blower design is quite easy to modify, just remove the plastic frame and you can strap a couple of 90mm PWM fans and you are good to go.

the reason i used PWM fans instead of oiling the original stock sapphire 280x fan is because it is wobbling when it is failing and there are times it reaches the gpu heat sink and makes noise.

maybe we should make a new thread about making home based swamp cooling tachniques, parts/materials etc. so home based miners can add more gpus/rigs to their setup..aside from reaching max current in our homes electrical circuit we also are reaching max temperature too..i'm still researching on it and substituting parts that are not available here..i am preparing for summer.

Even solely in the payment industry there are numerous other Dashs including:

Dash phone payments (singtel)
Dash cashless parking,
Dash restaurant/bar payments paywithdash.com
Dashpay card payments

Having the Trademark for crypto payments is very good and I'll admit I don't recall being aware of this.  The thing is, if I or anyone was to try to spread the word by, say, getting some pens printed with "Pay with Dash", it wouldn't be a very effective effort.  

I know you've mentioned, Tante, about Dash Nation name and although I like the concept, not sure about it for general branding and whether "Pay with Dash Nation" wouldn't really work.

Dashpay would be an alternative for branding but confusable with dashpay.co.za

Maybe we should be using the full name of Dash Evolution when Evo is released - "Pay with Dash Evolution" is still very snappy and Dash Evolution comes up top on,say, google rather than position 40 or so for just Dash.



those dashes, dash this, dash that, dash there.. are nothing compared to this

https://bitcointalk.org/index.php?topic=1020627.0

so xcoin/darkcoin/DASH is not a coin or cannot be called "DASH coin" unless it is called only DTRASH ... sorry name is already taken for a coin called Dashcoin.

Do we know If we are able mining through the wallet with XEON Phi co-processor

You can mine with any CPU but it's not worth it now because of GPU mining.

 The XEON Phi is 72 core processor but they would not show up beside your CPU for the Pascalcoin wallet.  While it would be amazing to see how fast it could hash blocks, I don't think it is compatible with the software.


these 72 core cpu's are like gpu's in design, utilizing pci express slots...maybe when time comes CPU mining won't die/phased out easily and we will have nvidia, amd, and cpu miners competing for hash... one problem, it seems pretty expensive, don't know price per hash ratio of these CPU cards though.

Those temperatures are possible at this overclock only with water cooling!
