PT Barnum was right...and then a bunch of used miners will be on sale in the next few months (when it gets warmer).

 Barnum is outdated - it's more like "every second" now not "every minute".

Do you'll know why they moved away from the standard server chassis?


 Low rig density.

 Current ASIC miners pack 1200+ watts into a case that is less than a QUARTER of the volume of most standard 4U cases, and less than a THIRD of most "shorty" 4U cases.

 I'm pretty sure the last rack-mountable designs were something BitFury or possibly the Spondoolies SP50 - and folks were moving away from the rack-mountable form factor for a couple years before THAT.

 Miners are NOT designed or intended to run in traditional data centers any more, as those data centers don't have the INFRASTRUCTURE to support the power requirement of mining.

 There have been temp sensors built into the ASIC chip on some previous designs I think - pretty sure the Spondoolies "Rockerbox" chips had on-chip sensing.

Semiconductor processes aren't shrinking at the rate they used to be..


 Welcome to the effect of Quantum Mechanics on semiconductors - and the impending end of the very long run of Silicon being the primary material for use in semiconductors.

 It says a lot that both Intel AND IBM have stated "10nm is the end of the road for pure silicon", and that IBM has specifically stated they are moving to a mixed Silicon/Germanium wafer for their 7nm development work.


 I have to wonder how long even that mixed wafer stuff is going to last, and what will come after that - if ANYTHING - for semiconductors - and how long it's going to take.



 And the important question is "Can it whistle IN KEY?" - all miners can whistle.

Global Foundries operates on a standard contract fab model so it's not really surprising that they built the BFL devices.


 Partly true - they do have some extensive contracts with IBM and AMD dating back to the "fab spinoff" days and amended/updated every so often that lock up a lot of their capacity if IBM or AMD wants that capacity.

 The contract fab model applies to whatever is "left over".



825  Bitcoin / Mining speculation / Re: 200 KwH Power Solution? on: January 12, 2018, 09:53:57 PM
Sounds like time to find a new location to mine?

I have to wonder how unreliable your Internet connection is going to be if "the government" only provides power 12 hours a day.

826  Bitcoin / Mining speculation / Re: Will mining still be worth it when the block reward is 1.562 BTC? on: January 12, 2018, 09:52:09 PM
There will be so many miners by then. You will need a big farm to get any real amount of BTC per month. Will the little guy at home still be making enough BTC per month to make it worth it?

 People probably won't be mining for the block fees by then - they'll probably be mining more for the transaction fees.

 Also, how much is 1 Bitcoin going to be worth by then?

 WAY too far out to predict anything - Bitcoin might have DIED by that point....
827  Bitcoin / Hardware / Re: (Review/Guide) WhatsMiner M3 11.5 Th/s, 2000W Bitcoin (SHA-256) ASIC miner on: January 12, 2018, 09:50:09 PM

I guess the article does say that the have their own power plant @ 0.04$ per kwh.  That is cheaper than many industrial rates (0.05-0.06$) in the US. 

 But a little more expensive than what most of the LARGE mines in the US are paying (3 cents/KWH or a bit less).

 Heck, I'm paying close to that where I'm at right now on a SMALL BUSINESS rate - and could drop to quite a bit less if I could find an affordable and usable place in one of the 2 "next door" counties (or grow enough to get into the "large business" rate here).

828  Bitcoin / Mining speculation / Re: Mining farms in the US how is demand calculated with electrical rate? on: January 12, 2018, 09:44:00 PM
Mine are open no cooling.  GPUs did fine last summer so we'll see how the ASICs perform.  Worst case I'll offset the heat slightly with some AC but I don't ever plan to cool the room down to 60 degrees, that's just a waste of money.

100% agree, I was simply talking about the cold isle of my setup, which would only be like 20-30 sq/ft. And I was thinking 70-75F would be fine, maybe even warmer.

 80 F is plenty cool - even Yahoo doesn't build their new data centers to go below that.

 Look up "yahoo chicken coop" on Google sometime.

829  Bitcoin / Mining speculation / Re: What is Bitmain doing with the new 12nm chips they're buying in 2018? on: January 12, 2018, 09:42:03 PM
10000 chips a month is a drop in the bucket - that would be ballpark 500 miners a month.

 I'd bet on these chips being intended for use in Bitmain's "AI Deep Learning" type new project, NOT in a cryptocoin miner.

830  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASUS B250 Mining Expert MB - 19 Cards! on: January 12, 2018, 09:35:43 PM
is there any place you know where this motherboard is available now ? I've been checking on all major shops and they're all out of stock. This Asus model is really attractive, it gives much more space to the pcie slots, with my current mb it's really difficult to put all risers next to each other due to the lack of space.

For those who already have it, do you measure performance differences between the different slots available? I have a 13 pcie motherboard and I have 3 underperforming slots.

 If you use risers that have the USB cable come straight out, clearance is not an issue at all.
 Right-angle risers you have to use in the "closest to the power connection" slots if you are going to use more than one riser per row. or you get cable interference that can make reliable seating of the riser "interface board" problematic.

 There should be no performance difference between the slots - try swapping your risers around to see if the issue follows the board.
 I've had issues where a "performance difference" turned out to be a marginal USB cable, and just replacing the cable with a better cable CURED the issue.

831  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 12, 2018, 09:32:30 PM
Well, no thanks to you slackers I can now answer my own question from earlier - the board is, indeed, a diminutive 195mm x 374mm. Surprisingly small, really. The PCIe slots are spaced 50mm apart so cooling of big cards with "impingement cooling"* might be challenged, if not marginal; cards with blowers should fare better.


 That is narrower than the Aoris 1080 ti - forget trying to use a "2.5" or "3 slot" card in that motherboard AT ALL except in the one "end" slot, or on an "every other slot" basis.

 It's very close to, or is the same, as standard "every other slot" spacing on common motherboards - even standard 2-slot wide blower cards are going to be airflow challenged.

832  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 12, 2018, 09:26:25 PM
Guys, would like your opinion on the following please.

I'm going to help two work colleagues set up their first respective mining rigs next week (both identical 6x1080).
I'm struggling on what to set them up to mine, basically. As they have very little knowledge of the whole mining experience, the logical thing would be to get them an account on Nicehash and forget about it.

Unfortunately I don't like that option for 3 reasons:
- NH is taking massive fees
- They'd have to setup an account because mining to external addresses would just take ages for them to see their gains
- NH is not my friend anymore, generally, for well-known reasons

I could set them up with DSTM and mine ZEC, but they'd potentially be forfeiting 30-40% of potential earnings.

What do you reckon? Zpool equihash hub? Ahashpool Neoscrypt hub?

 ZEC via Flypool has generally been close to Nicehash on earnings, also close to ZCL (but I don't know how well the pools for that coin work), and is a lot more widely traded than most of the "higher profit" coins that pop up briefly above it on profitablty.

833  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 12, 2018, 09:20:32 PM

HWInfo says my Ryzen 5 1600 draws an extra 52W while mining Cryptonight at ~400 H/s, while the TDP of the 1050 Ti is 75W, so the Ryzen wins in the hashes/W department as well.

But my point was more that the 1050 Ti really excels at Equihash so why use it on an algo it's only mediocre at like Cryptonight or Ethash?


 I doubt that the 1050 ti uses the full 75 watts when mining Cryptonight - the 750 ti certainly didn't, it used more like 30-40 watts out of IT'S 75 watt TDP.

 But I do agree crunch the numbers on all (or at least most of the common) algorithms for a GPU before deciding if it's good, bad, or indifferent and WHAT to mine with it.

Interesting article but factually challenged.

Prime numbers are NOT at the "core of cryptography", though there has been some use of them in the past.

While I like the GIMPS project and was a long-time participant, if any distributed project has had impact on cryptocoin mining it would be the Distributed.Net project which IS a cryptography project.



835  Alternate cryptocurrencies / Mining (Altcoins) / Re: Are 1070 TI's the next best GPU for mining? 4.7 sols per watt on: January 12, 2018, 08:45:32 PM
Probably the same, but don't have a Strix to test with.

I would say IN THEORY it might show a hair higher if you push it to max TDP due to slightly better cooling, but can't say FOR FACT if that is the case - and if mining for efficiency the cooling isn't enough of a factor to matter on ANY of the cards I have worked with, even the Zotac Mini.

836  Alternate cryptocurrencies / Mining (Altcoins) / Re: SGMiner on XBOX One on: January 12, 2018, 08:33:53 PM
Obviously you aren't bothering to READ what I am posting.

I didn't SAY "this GPU can only address 1 GB". I said the A10 had that limitation, and that it *MIGHT* apply to the APU in the XBox One X.

One typo on DDR3 vs GDDR3 doesn't mean I don't know the difference or make me ignorant.
Are you going to try to tell me you have NEVER misstyped something?

I use capitols for emphasis - this is a VERY long standing online convention dating back at least to UseNet and PREdates the Internet as such, if you don't understand it that makes YOU the ignorant one.

GPU internal voltage tuning and control does NOT equal "undervolting", where the USER dictates to the GPU to use less voltage than it is designed to use.
Ditto "Hovis method" to make the GPU more efficient, which has actually been used on other GPUs before as well as CPUs.
Again, YOU showing ignorance not me.

I've BEEN civil - you are the one that started name-calling and being insulting for no reason.

PS4 has had LINUX on it and "been hacked" since at least 2016.
https://github.com/fail0verflow/ps4-linux
There were quite a few other postings at that time about the subject.
Do you even bother checking facts before you post anything?
Seems odd you calling ME ignorant so many times when YOUR ignorance is so repeatedly blatant.

I have NEVER SAID ANYTHING about "not worth mining on", my entire point has been "don't ASSUME RX 580 level performance" not "don't bother mining on them at all".


If you can't be bothered to READ AND UNDERSTAND what other folks type before commenting on it or understanding basic common Internet conventions, YOU are the one that should stop posting.



837  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 11, 2018, 08:20:44 PM

* - Cryptonight performance, however, is especially terrible at around 385 H/s - my Ryzen 5 1600 is faster - while I could only manage about 13.4 MH/s with Ethash despite that this card has Samsung memory.


 50% better than the 750 ti that it replaced - and similar power usage if I remember correctly from postings folks have made about it.

 But yes, quite a few of the Ryzen CPUs can do better - abet generally at same-to-HIGHER power usage.

838  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 11, 2018, 08:18:17 PM
My gear is set up in my unfinished basement, about 28 feet away from the breakers.  It's just where they ended up, near a workbench and where I had some portable shelving.

As I look to add new outlet(s) I was thinking I'd just put it next to the panel for now because it's easier.  I saw someone mention EMI and other interference when you travel some distance, and I'll be pulling about 4400 watts, so it might be nice not to have all that right over my desk (my desk is between the panel and my shelving / workbench.

Is it a good idea to locate your mining rigs and power outlets right next to the breaker panel? 

 EMI is a non-factor. 60 hz doesn't generate enough EMI for computer gear to notice.

 Close to a panel makes for shorter runs and slightly less IIR losses in the power feeds - it's not enough to be a big deal but it probably would save you a FEW watt-hours a month.

839  Alternate cryptocurrencies / Mining (Altcoins) / Re: Happy New Years! Seventh alt coin thread! on: January 11, 2018, 08:14:50 PM
any news of custom vega 56 ?

 MSI had one up on NewEgg for a VERY short while but it's out of stock again.
 A few others have been anounced but haven't seen them actually for sale yet even when listed.



840  Alternate cryptocurrencies / Mining (Altcoins) / Re: EWBF's CUDA Zcash miner on: January 11, 2018, 08:11:08 PM
EWBF + Poloniex =  Kiss

Sure until Poloniex gets hacked again. Storing your crypto on exchanges is the worst thing you can do with your money.

 You forgot the mention the FREQUENT issues Poloniex has with "losing deposits" - sometimes for a few days, sometimes for weeks, sometimes for MONTHS.

 At this point I'm inclined to think that NICEHASH has a higher trust factor.


 Yes, EBWF works fine with Nicehash - point it at their equihash pool directly if you're running LINUX, do the same OR run their front end under Windows (they included EWBF a while back as an option).
