I currently have 3 rigs on FAH, pretty close to identical.
2 NVidia 1070 folding, 1 old HD7750 doing Moowrappper along with the A10's GPU unit.

 Nope, shouldn't be hard to figure out who I am on Team Curecoin - just check the top 10 on "24 hours".

 9-)

 They net about .6 cents/watt of system use - could do better if I optimised them more but I have a VERY longstanding commitment to the distributed.net project.
 This works out to a fair bit more than a 300% profit vs electric useage at my current power cost JUST on Curecoin (I've not seen if my hopefully fixed FDLC setup will get me more).



 BUT!

 Most folks pay quite a bit more for electric than I do here in Central WA, and the income / $ invested isn't as good as a optimised ETH or XMR rig can do right now.

 Shipping should be a little less than $100 per earlier posts.

 Power at 10c/KWH is HIGH for most miners, "best case" would be more like *3* (and for me currently 4.5 but hopefully under 3 sometime next year).

 On the other hand, I DO expect the network hashrate to about double over the next year, possibly a little sooner - depends on how fast they can get units built and shipped, and on their chip supply (Bitmain has had OBVIOUS limits on how many chips to make S9s they could get at a time).


 One up side of the delays - my A2s have managed ROI. 8-)

Because the CLIENT doesn't know for sure if you still have the coin.

If it is not fully synched, it CAN'T determine if the transaction is valid or not - which is why a WELL WRITTEN wallet would not let you create such a transaction.

Client shouldn't allow the transaction to be created in the first place if it doesn't KNOW you have the coin.

You can build a pair of 4GPU RX480 based rigs for less than this thing appears to cost, and have a high probability of better reliablility and MUCH easier resale ability.

Without the actual price, though, I can't say for sure that you could build *3* 4 GPU rigs for the same price.

Looks like we might have had a few rigs come over from EVGA.

One of the pics looked like they take a standard card, mount it on a custom multi-riser setup, then put a custom passive HS on each card.

 If they ARE charging $3000+ for the things, it's just a straight "gouge you because it's pre-built and pre-configured" situation and fairly likely to be legit.

Seems like a major security hole though, to allow a send transaction when you're not syncronised.

-l=4x20

or 3x15

etc.

that equal sign matters.

 Not for Monero. Some of the high-end many-core CPUs put out just as much as many mid-range GPUs.

 I'm going to be curious how well the high-core-count Zen stuff does on XMR.

They're saying 8 AMD 480s to get to 256 MH/s - which isn't unreasonable if you can push them hard enough.

 The hashrate they're quoting is not $800/month though - that's VERY close to what I get out of my farm, and I only see about $520 right now NOT counting electric use mining ETH (they might get a bit more on XMR but that's gonna vary and XMR isn't a LOT more profitable than ETH if at all).

 127 day ROI is NOT realistic unless the price is pretty low - where IS the price, I don't see it quoted anywhere on the page you linked?



 

*NO* CPU used in a PC (possible exception for laptops) has been able to run without a Heatsink without overheating since some of the very early low-end AMD and Intel 80486-class units.

 The reason that Intel ended up releasing the original Pentium in 60Mhz and 66Mhz instead of 60 and 75 is that even WITH the best heatsink/fan tech of the time they couldn't keep that generation of Pentium from overheating at 75 Mhz (that was the LAST CPU generation that ran on 5 volts, the next gen of Pentiums went to running the core of the CPU at 3.3 volts).


 Don't even THINK about trying to run any current CPU without a heatsink (no fan can work if the heatsink used is specifically designed for passive cooling and the case it's in provides enough airflow, but that's generally limited to low-power and server-type setups).

 Very much so, as I recall my connection rate reported by Windows was something crazy high like 8 or 10 MB/s even though the actual speed of the actual connection was tons slower.
 BTW, my experience with anything ZTE has been uniformly negative - IMO ZTE builds JUNK and should be ignored.

 This is actualy the norm for anything resembling a serial modem, back in the days when dial-up was common most modems had a connection to the computer that was a lot faster then the actual modem connection speed (mostly because of data compression being common in 9600 baud and later modems).


 As far as your 2GB cap goes - I was on one of the Virgin Mobile "Unlimited" connections - my SPEED got capped at 5GB downloaded after about the first year when they unilaterally changed the plan to a semi-capped plan, but the speed cap was pretty close to the NORMAL speed I saw and was pretty much unnoticeable as a result.

 Unfortunately, unlimited seems to be pretty much dead on cellular connections - even that old Virgin plan got phased out and only folks that already had it and kept it current could still use it.

 And yes, I'm aware that it varies - not just by country, but sometimes by area IN a country and always by vendor.

Odd, every time I've tried to use bitcoin-qt to send coins when it wasn't synched, it refused to do so.

post your command line, something isn't right

Would make more sense if the US Coinfest was somewhere near central Washington where there are a lot more miners than any other part of the US.

Southern California probably has the LOWEST density of miners in the US due to the insanely high electric costs in that area, you're not going to get all that high of a turnout when you make the bulk of prospective attendees travel halfway or more across the country to get to the event.

Seattle or Spokane areas would be fairly close if you think you need a LARGE convention site.



 As far as your use of crapcha goes - don't bother, it does very little to weed out spammers IF ANYTHING, while ticking off legitimate users.

If bitcoin core DOESN'T regularly download blocks to update the blockchain, it becomes unsynchronised and you can no longer do anything with it 'till it IS synchronised again, as it doesn't have the correct and up-to-date information it needs to DO anything else.

 If you want it to stop for a bit, just shut it down.

You apprear to have a bad or flaky adapter.

 I was able to get Bitcoin-QT synched on a very poor throughput (commonly 200-400 Kbps - BITS not BYTES) 3g cell connection a couple of years back.

 Was it slow? YES.
 Did it have to restart a few times 'cause the connect was flaky? YES.
 Did it work? YES.


 I will concede that the blockchain was "only" about 60GB at the time.


 I was then able to mine with multiple ASIC miners on that connection with the only issue being a slightly high reject rate due to poor latancy.


 3G is not "useless", though it can be painfully slow.


 And as it happens, in my case the bottleneck WAS the download time, though Bitcoin-QT is PAINFULLY slow on its pre-allocate routine.


 3G does NOT mean "3 Mbps" - it means 3'd Generation cellular. The FASTEST 3G is capable of in theory is about 1.5Mbps, but in practice it tends to be a lot slower than that.

 By YOUR so-called logic, a 4G cell (current LTE for example) would be a 4Mbps connection - but they're actually more like 50 in theory and commmonly well in excess of 10.


 If you don't know what you are talking about, you should just stop talking.

 Right now, the only miners available to individuals are the Antminer S9 and Antminer R4 - www.bitmaintech.com

 IMO the R4 is badly overpriced, the S9 is somewhat overpriced, due to no competiton - I'd wait a couple months to see what happens, there are other alternatives that have been announced and a couple of them SHOULD become available over the next couple months or so.

 *IF* you have a substantial amount to invest into mining *AND* your power cost is very very cheap (5c/KWH at most, preferably 3c or less) it's entirely possible to make a living from mining - but it is somewhat risky.

Absolutely no point to that dehumidifier - the cold air going into the room will have very little humidity to it once it mixes with the warm air already in the room.

You do not have enough intake air inlet to match the outout air. Those need to be at least CLOSE.

Taking air in from close to where your output air is going ends up recirculating some of that hot air. Your intake should be on a different wall from your output, optimally OPPOSITE walls.

 When you say "have a low temperature" what temperature do you mean? 10C? 15C? 20C?
