Sixth alt coin thread I forgot to mod last thread.

[citronick]

Question about the trezor.  How exactly does that thing work?  Like it doesn't download the entire blockchain does it?  Does it rely on some kind to web services from trezor or do I have to run the trezor wallet on my machine and that downloads the blockchain?

The device talk to Trezor servers so there is no downloading of blockchain.

The backup server is "https://blockexplorer.com"

So basically all you need is the Internet.

Trezor hardware device keeps the private keys intact.

Interesting password mechanism that requires you to follow the dynamic numeric schema on the device.

Any send transactions and signing needs physical double-confirmation on the device.

I guess all of the above makes it very secure and foolproof.

Its better for day to day wallet use, IMHO vs the Nano.

Antminer s9 is for sale right now I ordered six

I think BTC will have multiple forks to mine next year and the price will hit around 6k

[citronick]

i don't get what citronick is saying about "better heat control" but risers are imoprtant to make space between hot gpus, the closer they are together the hotter they get..

quality risers are good, most of my risers from late 2013 are still going strong.

Avoid the molex powered risers or any of the v1 to v5 risers.

 Why avoid Molex - the connectors can EASILY handle the needed 75 watts (the actual connectors are rated for about 150 watts IIRC) as long as the WIRING is beefy enough.

 Avoid SATA definitely, those connectors aren't rated for more than about 45 watts and WON'T handle the load.



 to rslx - if you're willing to wait, your best choice is to buy from the manufacturer(s) direct.

One of my China suppliers shared with me that the worst riser power cables are molex and sata because during the mining boom a lot of back-alley small shops producing sub standard risers and M2 adapters.

If you go to Aliexpress, the good premium risers usually around 6-8$ bucks each. But now you can get 4-5$ each with poor quality molex and cable build.

Even the sata type has 2 versions - those that are "clamped" together usually has very high failure rate.

Those original powered risers with molex circa 2013-14 were probably the best you can get because the molex pins and cables meets/exceeds the standard.

I wonder what price power usb risers circa 2013-2014?

Antminer s9 is for sale right now I ordered six

I think $7000 or more by Christmas is very likely.

Bitcoin futures trading and ETFs coming by year end - so more institutional money coming in from stock market.

No surprise JPM's CEO claiming Bitcoin is a fraud, bubble etc... because a lot of their investors taking money out from stocks to Bitcoin (and crypto currencies).

wow you are more bullish, lol I though I was being overly optimistic, you really seem to have your ear to the ground .

Thats why I want to diversify my farm a bit to milk the nicehash spikes when BTC is rising, I calculated if I had kept the two S9 11.5TH I sold last year and sat on nice hash with them I would have quadrupled my investment on them.

I had to sell them because they used too much power compared to GPU's for the money they made back in January.

I also need to diversify my farm like you guys now that I have access to more power, I feel like I am too GPU heavy, even though I have a mix of R9 NANO, 1070s, 1080 TI's and like 100 RXcards with some D3 as well on order.

I ordered one  pdu  55 for that is good price.  looks like I can turn it on and off

I'm sure you will like it. Just tested one of the PDUs and it worked fine. Can manage and measure via telnet/ssh/snmp or built-in web server. Has DHCP enabled by default. Needed to reset to factory defaults to regain root access. http://www.baytech.net/wp-content/uploads/2016/04/Reset-Modular-Horizontal.pdf

One other unit I opened randomly had its management board cable unplugged. No idea why.

He cancelled my sell.

Oh well.

I contacted the BayTech these units could solve allot of my fine tuning issues , they linked me up with a local supplier and I'll find out what the price is for new/refurbished units .

He said they also provide Metering for Panels, and individual outlets , could be interesting.

Anyways, I think focusing on the riserless mobos is better strategy moving forward. Save money on unreliable risers, better heat control and lessen OS compatibility issues.

I love the sound of eliminating risers if possible. Just the time saved troubleshooting the rig if it's acting up would be pretty valuable, even without the additional cost savings. I hope that somebody makes one with ample enough spacing to run a full 6-8 higher wattage GPUs, such as GTX 1080 Ti, Rx Vega etc.

i don't get what citronick is saying about "better heat control" but risers are important to make space between hot gpus, the closer they are together the hotter they get..

quality risers are good, most of my risers from late 2013 are still going strong. and add to that my 775 motherboards circa 2006-2007 that are paired with these risers are still working...

look at that very long motherboard and look at the capacitors in between pcie slots, if only one of them gets cooked you're gonna get some headaches.

You must have risers fashioned by jesus himself Ive had risers go bad all over the place , pretty much given up dual mining due to exploding risers or pcie slots connected to risers, It wasnt so bad with hawaii cards never had much issues withrisera on my 390 a s 290x builds unless the risers were doa, but with polaris and even Pascal it seems they can draw excessive amounts of power from the pcie slots , like spike or something which usualy overload tbe pcie connector or the sata part and fuse them.  

Honestly I think it has something to do with the die shrink from 28 to 16 and the power distribution circuits being poor
on this generation v

i'l share later pics of my old risers later when i get home.. and my new ones...forgot the versions..they did experienced eth dual mining but changed my strategy. i stopped dual mining eth, shifted to zec, undervolt a little(for some of my cards) and increased the number of my cards.

it maybe profitable dualmining eth but with increased number of cards profits level up too.

Another good, but more expensive option for a PDU with switching+metering for individual outlets is the APC AP8641 (that particular model).

I have two and will be getting rid of them because they are too large and simply overkill for what I use them for. New they go for about $1,500. Sometimes pop up used on ebay for $300-$500. There is one brand new unit going on ebay right now with a good low starting price. If that one goes for well over 200, you can shoot me a PM and we will see what we can do.

quality risers are good, most of my risers from late 2013 are still going strong.

The non-powered ribbon style risers do work nicely especially if they are well made. However, with newer GPUs requiring more power, the newer risers that have voltage control, better capacitors and 6-pin power (v6c/v7c?) is the gold standard for riser based rigs. Avoid the molex powered risers or any of the v1 to v5 risers.

Better heat control can be achieved more efficiently with riser less mobo builds, using in conjunction with powerful "Scythe" fans placed back and/or front of the cards depending on reference/blower GPU or otherwise.  If done properly, you could get 1080tis with paper thin spacing at beast mode and still attain acceptable temps.

Currently, I use a "vertical GPUs on S hook design" for the RX ETH farm and also using zip-ties for the newer builds on TB250s and H110s....

I will try and get some pictures to show my experiments in the warehouse..... but my group members is kind off anal about showing pictures of the farm.... but will take some discreet shots.

_______________________________________________________________________________ __________________________________________________________________________

that cooling solution might be enough for the place/country you are mining it but other countries/places that tend to be hotter than yours, that setup might not be good enough for them..

he lives in a tropical country with  high temps and high humidity.

_______________________________________________________________________________ _______________________



regarding "Scythe" fans or any solution like that....that's basically blowing the heat in tight spaces between gpus, heating the room and then exhausting the heat from the room to outside..that is... GPUs--->small fans---> room exhaust (3 step cooling)

for me it is better to make wide space between cards (no need for "Scythe" fans or any solution like that), the room heats up and then you exhaust the heat from the room, this way it is more simple and less energy/fans/effort used....that is.. GPUs-->room exhaust (2 step cooling)

that "small fans" solutions for me is just a remedy to certain areas/situations in my mining room where temps tend to become hotter (places where it is getting crowded and cards get uncomfortably hotter)...

i totally agree with your setup if risers are pain in the ass for you and the country/place you are mining is advantageously cool enough.

just think of it..you underclock/run a GPU in its most efficient power tune/bios mod to become power efficient overall and save power(hashes per watt)...and then you add a 6w fan as an additional power consumption.

yeah 6 gpus  saving 15 watts each and spend 6 watts back net 84 watts.

Riser free vs lots of risers.

I am a riser free guy in principal   but I do use risers.

What I have found is  heavy clocks burn risers  and don't burn mobo's

I have burned more risers then mobos.

I am at the point all my gear is paid  and I have:

spare mobos.
Spare ram.
spare psus.
spare hdds
spare ssd
spare usb's

mostly because  I pushed in the 1080 ti mining  which removes  needs for slots and or risers.

3 card  1080 ti rigs riser free  =   7 or 8  card 1060 riser rigs.

a single 6w fan cannot blow air in between 6 gpus, ideally you need 5, that's 6w x5 = 30w

usually what burns in risers (from my experience) are the molex to sata adaptors or when direct molex connections are loose

why not 7 or 8 card 1080 ti riser rigs?

i get it that you have spares and using them is reasonable but using riser, uses less power and space than using cpu/ram/processor/board/ssd-hdd-usb.

i got spares too, using them as combination of riser-free and riser GPUs.....but my main setup in my mining room is riser GPUs utilizing all pcie sockets.

Well I do use risers but I have places to run pc's  for free power.
In my case  this means a 50-50 split of coins.
I have 3 office locations  with friends    that  have the following restrictions.

Gear must be quiet.
Gear must be in a case.
Gear must be about 1000 watts per location.

here is one setup  3 pc's  6 1080 ti's
fully paid for  .  and  the coins in the btc addy  are ½ his and ½ mine.

So  while 6-7 dollars a day sound small  my costs are zero.
My friends costs are zero.
and the coins grow.
that addy is a stand alone trezor.
and will just grow.

Do you notice the trezor being very slow or anything when you use it to send a bunch of micro BTC payments / located them? I was under the impression it was a mistake to mine to a hardware wallet but maybe that's a misconception ?

My group has 50% BTC Asics (S9, A7), 30% non-BTC Asics (L3+, D3, A4) and 20% (GPU rigs) -- this is what we feel is the most optimum and reasonable daily revenue (ie after expenses).

I am doing crypto day trading too and my trading community has a lot of ground information like CBOE including Bitcoin futures trading etc....

Very nice you are quite diversified, prepared for the future , trying to get the same way but its been hell trying to get hardware at reasonable prices, finnally with the China FUD it seems Asics are getting to be available now ,
unfortunately my funds are now limited too from the lower prices of stuff I held and projects I took on earlier in the year when the prices were booming lol

Any send transactions and signing needs physical double-confirmation on the device.

I guess all of the above makes it very secure and foolproof.

Its better for day to day wallet use, IMHO vs the Nano.

Thanks for the explanation.  I was just wondering what would happen if one of those two services were to go down.  Would there be a manual way to still get to your coins or are you screwed?

I think there is up to 4 servers at Trezor and there is also the public one at blockexplorer.com - both sites down - then yes, you are screwed.
So far I have not  got any downtime issues - I think the Trezor servers are geographically located to have 24x7x365 access.
Trezor is not #1 hardware wallet for nothing - I guess.

@Marvell2 - If you are serious about mining farms - you got to have a sizable fund for it. My group just got 168 x A741s from Canaan waiting to to be powered up - this is not a big order but not small too, so we got to work directly with their order processing team. It will be good to have referral to help speed things up. In my case, Kano help me link up with Canaan CEO. This new batch will bring our A7s total to 323 units at Cryptoboreas hosting, in addition to the 108 x S9s. A7s are rock solid - very little babysitting compared to S9s, expect up to 15% failure rate - we got things working eventually after Bitmain parts replacement / RMA but the turn around time was very long - up to 2 months.

@citronick jesus 168 units? each pulling 1100 watts ? and you already have 108 S9s that is a huge farm comparative to most.  I hear good thing about the A7 but its hard to pass up the efficiency of the s9 at close to 14TH for 1400 watts, I just hope these ones are not duds.

Yeah I hear you on the go big or go home but , I'm working with a much smaller bank roll and I like the ability to have direct access to my gear in the house and the garage for now at least.  I only have access to around 130k or so watts of power so I have to go with more efficent gear
GPU's and the 14NM asics. 

If some of my stashed coins strike big I will look into hosting a large amount of asics but for more I'll just Marvell at you big time miners /respect

worse comes to worse you can import the trezor seed words/passphrase into another (bip38 or bip39? cant remember) wallet and all your addresses will be there. so even if all the trezor related stuff goes down you still have access to your coins.
