Given the A4 specs a "1000 watt power supply", which will probably be pulling somewhat less than that in actual usage, where the HELL are you comming up with that 1100 watt claim?


 Yes, the Titans are fairly close on efficiency - they'll probably stay profitable for the forseable future unless you have REAL high electric rates - but they're not nearly as close on efficiency as you seem to think, *AND* their track record of many dead cubes makes their reliability very suspect while the A2 was rock solid for almost EVERYONE that ever used one.


 I can see a day, probably in the next 2 years likely less, when the A2 becomed non-profitable at 3c/KWH electric and the Scrypt miner market becomes basically a 2 horse race betwen the A4 and Titan - but those Titans that are still running by then will definitely be the LAGGING horse in the race.

 Delays of more than a YEAR = "just fine"?

 Interesting concept that - and I'm not even going to START on the many other issues with KNC that drove them to bankrupcy despite their own in-house massive mining efforts.

 More like 7 MB a month or less - probably less.


 I used to have a farm of 5 A2 Innosilicon Terminators, about 12 cards (mixed, HD7850 up to R9 290s) worth of Ethereum miners, and rarely used more than 100 MB in a day for mining AND everything else I did on that connection (downloading patches for certain games WOULD drive the usage way up for a day).

Find out WHY it happened before you do ANYTHING in an attempt to repair this.
If you don't that's a fire hazard waiting to happen and you might get UNLUCKY the second time around.

Given CureCoin is largely based on F@H in certain ways, not hard to get the two confused for the uninitiated.

 I'd forgotten about the Baikal - don't know if the other 2 X11 ASIC are still selling or not at this point, though I suspect that original one isn't as it's been blown out of the market so badly since.




 And yes, it would take about 6 KW to run a 60TH miner with the stated efficiency of their bitcoin miner.
 Not impossible - Spondoolies DID announce that SP50 with *10* or some such PS in it and may have actually built a few for private data hall(s) somewhere before they died - but NOT likely at all in a 4u form factor.

 Only BitMain right now.

 Canaan should be selling something semi-soon, Innosilicon should be shipping the A4 in another week or two.

 In theory BitFury and BW.Com could but they seem to have decided to stick with sales to "industrial" level miners for the forseeable future.

The "20 nm" claim is an interesting BIG RED FLAG, as 20nm tech as i recall didn't EXIST (the next step down from 28nm was 22nm, and THAT was very little to no more efficient than 28nm).


 They also claim to be "experienced" at miner design, yet they come out of the blue with this stuff.



 This has "SCAM" written in 10 foot letters all over it.,

 Actually, just Bitmain - though Canaan has announced they're working on a next-gen miner, and the Innosilicon A4 should be shipping real soon (dunno what happened to the A3 though, have heard NOTHING about that for months).

 In theory, BitFury and BW.com (LKEtc and co) could do so but they seem to be sticking with sales to "industrial" scale miners.

They may have built out their initial chip alotment and dropped it after *2* other X11 miners of BETTER EFFICIENCY showed up.
Dunno if they'd bother working on a new generation that's competative with the Baikal.

 ASIC USB sticks are a lot more efficient though - and none of THEM are profitable any more except the Moonlander and possibly the Gekko *IF* your electric is cheap enough.

 There is NO BLOODY WAY you "got raided" for having high power consumption.

 I don't care how much you CLAIM about "there is nothing else going on", you got raided for SOME OTHER REASON.



 Chelan PUD doesn't hate bitcoin miners, the PUD just hates the effects on their infrastructure and the reduction in revenues 'cause they have less "spare" capasity left over to sell for much higher rates that drops their revenue due to the large number of large Bitcoin-related farms that have moved into the area or started up in the area over the last 6 years or so.
 This is not to say that individual members of the PUD and individuals in the area aren't clueless about bitcoin....


 Next time they whine about it only being used for drugs, try pointing out that large retailers like Amazon and Newegg (and I believe I remember seeing *WALMART* is now accepting Bitcoin as a payment option on their website) accept Bitcoin payments.
 Not exactly "drug specific" there.

 Can also point out that the IRS considers Bitcoin legitimate and has made a ruling on it for tax purposes.

 

 A 2GB 750 ti is ballpark a 210 h/s Monero card out of the box (depending on model) - at it's power consumption, that makes it very efficient (though overall SYSTEM power consumption isn't good).
 IIRC the top-end cards are generating less than 1kh/s on Monero (possibly exception for some of the dual-GPU type cards).

 It's about a 3 Mh/s card as of a month ago on Ethereum, which is rather poor for the cost of the card and it's power usage.
 Even going with the same-generation GTX 950 jumps the Ethereum hashrate up to about 10MH/s out of the box for VERY little more money.

970 is a generation old, 480 beats it hands down on almost everything related to mining.

 This IS the "altcoin mining" forum.

 To the OP - foutside of CPU-specific coins, the CPU has pretty much zero effect on mining speed - I've got one machine on Ethereum running triple R9 290 GPUs with a Sempron 145 (older SLOWish single-core) without issues.
 
 Videocard - depends on what you are mining on. NVidia usually is competative on production per watt, but tends to cost more so production per $ is lower, there are a few exceptions though and this generalization gets changes to the specific details as mining software changed, mining coin values and difficulty changes, and newer cards show up.

A miner is very close to a resistance heater on BTU/watt ratio - close enough you won't see any practical difference.

There is a TINY amount that gets used for communication but in practice it still turns to heat - just in the LAN switch not in the miner - and the amount is TINY compared to the total power usage of the miner.

Those "low cost processors" STILL eat power - and have very poor performance per watt vs. ASIC (where available).
They might be competative on a per-watt basis vs conventional CPUs, but there doesn't seem to be enough of a market to JUST add on a "CPU + RAM" to make the things viable - and you ARE going to need the RAM to be able to mine with them, at which point any potential cost savings drops to near nothing on a hash/$ and hash/watt basis vs existing multi-core server CPUs on existing motherboards.


 It's going to get worse once AMD starts releasing "Zen" CPUs with 16+ cores per CPU package/chip late this year or early next year.

The CPUs available on sticks are all rather low performance with low memory available on the stick and the STICK prices are expen$$$ive.
 
Those CPUS also eat a lot more power for their POOR performance than ASIC do.

Trying to mine *BITCOIN* on a CPU is a waste of time, electric, heat, and wear and tear on any CPU.
You'll be lucky to make *pennies a year* while you pay *dollars a week* to run the things.

 Altcoins are in a few cases different, go check out the altcoin mining threads.

 The issues were with mining on Windows 10.

 Windows 7 has never had these issues.

 With that said, mining on LINUX is a lot more stable.
