Zeus was never particularly competative, though unlike some folks they actually did (eventually) deliver some product.

 The last project they were involved in, AFAIK, was making part of the Innosilicon Farmboy gear under contract to Innosilicon.

With cheap enough electric, the S7 and Avalon 6 will still be profitable - barely.
The B-11 should also fit that description, if BW.Com ever starts selling the things.

 The big questions are Bitfury (supposedly having a miner available by end of March, but looks like they're going to miss that a bit), and Innosilicon (A3 due any day now, from what they posted a few months back), and BW.com B16 (due "in 4 months" or so).

 There is also the question of when Bitmain will have their next gen miner chip/miners available, as they announced they were working on the next gen as part of the initial S7 announcement....

B16 published specs are a bit inferior to what Bitfury has shown, and a claim of 4 months from now isn't impressive - but at least it means Bitfury will have SOME competition around the halfing....

Worst case to find your IP address (I had to do this with all of the A2 units I bought from Zoomhash):

 1) Pull the SD card
 2) Mount it as a drive on a Linux machine
 3) poke around in the rc.d directories off /etc
 4) ONE of them will have ip address(es) in it


 No, I don't remember the exact file offhand, and I'm not in the same state with my machines right now to go looking for it.

There is no such thing as a standard electrical outlet that will support the wire that MUST be used on an 80-amp circuit, though there might be specialty stuff that can do so - but you can't plug a miner into such specialty outlets.

 Subpanal is the SAFE way to split out the capasity of that 80 amp circuit.


 I'm not sure if there is such a thing as a NEMA-spec outlet for anything over 50 amps PERIOD (I am very familier with the ones used for older mobile homes, which are no longer acceptable under the NEC for NEW installations but are acceptable in many or most locations for existing mobile home installations and for use with RVs).

there should be a crontabs file in /etc If I Remember Correctly (IIRC).
You should be able to manually edit that.

It's already been mentioned in at least 2 other threads in these forums.

I ran 5 S5s, a Sp20, and 5 A2 Megas with 100-base gear - on a sat connection - easily.
I'm not sure if the whole setup managed to eat 1 megabit/sec - think it was more like 1-10 KILObit/sec ballpark.

 10Base would be overkill for miners at this point, except you can't get less (unless you have ancient Xerox gear that ran the original pre-10 Ethernet).

Litecoin (or any scrypt coin in general) has been UNPROFITABLE to mine with anything but ASIC for a couple of years now.
Even with FREE electric, you will probably have the rig die before it can mine enough to pay for the GPU(s) in it, much less the rest of the rig.

You want to look at non-SHA256 non-Scrypt coins for a GPU-based rig unless you like paying your power company lots more than you get back in mined coin value, OR you want to look into ASIC gear.

Most of my older switches are the FS108, though the newest are GS108 or GS105 (Office Depot had a heck of a sale on the GS105 a while back, so I got a couple).

 Nothing inherently wrong with plastic - my 3Com switch has a plastic case - but in Netgear the plastic-case stuff tends to be their relatively cheap stuff.

 ROFLMAOSC!!!!!!

I would wait to see what shows up in the 14/16nm generation.

 With free electric, you're not worried about efficiency from a cost standpoint.

 With only 1 KW electric available, though, you NEED to maximise efficiency to maximise your TH.


 Don't waste time on an S7. They're dropping price FAST of late, you'll probably not mine enough to make up for what you lose on trying to sell the thing used, and the next-gen gear SHOULD be showing up fairly close to when you'd RECEIVE the thing if you buy it from Bitmain.

 DO go ahead and get a good Gold-efficiency or better power supply - preferably Platinum with your power limit.
 A couple percent better efficiency can make a difference in your situation.

I've never been impressed by TP-Link, though they're not BAD - unlike some of the other cheap stuff out there (DLink and Linksys come immediately to mind).

 I don't bother looking at reliability after a couple years. If it's a switch and it don't last a decade, it's cheap junk.

 I've tended to stick with Netgear "blue box" switches - they just keep going and going and going (some of mine are pushing 20 years and STILL running fine - as is the one Netgear blue-box 10-Base-T HUB I have, at close to 25 years of use, though I'll probably retire that one eventually as I'm moving everything to at least 100-Base).

 I do have one old 3-Com switch, got it cheap at a hamfest along with a buncha 3c509 cards - the cards are about to get retired as they're ISA and I am retiring the last of my ISA machines this spring/summer (20+ cards all 20+ years old, a few have lost the BNC port but ALL of them still work on twisted pair and most are 100% functional still), the switch just keeps running....

 I did make the mistake of buying one of Netgear's "consumer" type plastic-case switches. Once. Never again, it lasted a few years (past warrenttee) but is more than a bit flaky in recent usage, to the point it's about to get replaced.


 To a real degree, you get what you pay for in network switches.



 BTW - for miners, Gigabit is serious overkill. On the other hand, it's gotten cheap enough to make the extra cost a long-term investment if you buy GOOD gear.

There are ZERO scrypt coins that are even vaguely close to profitable to mine with a GPU.
 Total waste of time looking for miner software for that setup.

 Gridseed ASIC (GC3355 based orbs/blades/etc) aren't profitable for Scrypt any more, unless you have very very cheap electric, and those units were easily MORE THAN 10x as efficient on hash/watt than any GPU ever managed (2.6+ Megahash per side for under 60 watts on the blades I had per side, under 50 for the non-fan sides).

 Scrypt was also pretty much ruled by AMD GPUs, as it was a fairly simple algorythm well-suited for Stream units (Nvidia does better when the algorythm is more complicated), though Maxwell Nvidia cards might have been almost competative if they had existed a year or two earlier.

 I was specifically talking about Litecoin there, not mining in general.
 DO please pay attention to the context before you go off on someone.

 BTW, if I'd bought my SP20 and my S5's during the price war, I'd have VERY EASILY achieved ROI on them just by mining, even with my not-particularly-low electric rates.

 There is almost no chance of RoI RIGHT NOW on any currently-available ASIC, but that will almost definitely change once the full-custom 14/16nm generation manufacturers start selling miners to the public (or chips to third-party manufacturers for THEM to make miners out of as the case may be).

Litecoin price has been quite stable in the $3-$3.50 range since about a month after the Litecoin reward halfing last summer.
Difficulty has been fairly stable, with a VERY slow creep up trend.

 Downside - go ASIC or go home, GPUs haven't been profitable for a couple of years or so even with VERY VERY cheap electric, and even with free electric the GPU will probably die before it manages to mine enough to pay for itself (much less the REST of the system supporting it).

The Chinese exchanges started accepting fiat payments for Bitcoin months before the "Mike Hearn" stuff - and the current price DOES in fact reflect the aftershocks of the resulting BIG JUMP at the time.

 If the Chinese Government creates a digital currency, it might use some of the TECHNOLOGY from Bitcoin but it WILL NOT BE BITCOIN.

 S7 is 3 strings per board, with a varying number of chips per string depending on the batch.



 I'm not a hexa yet - give me a few (too BLOODY few) more years - I AM an Eisenhower baby though. 9-)

 The web software is bugged for setting voltages.
 Use it to set initial info, then SSH into the machine and manually fix the entries in the chrontab

 It worked - mostly - but when I did daily voltage schedualing sometimes something would hang and cgminer would never restart.

16 dollars is CRAZY BLOODY EXPENSIVE for a fuse socket/holder.
 Should be able to get a 20-30 amp CIRCUIT BREAKER for not a heck of a lot more than that.

 
 MUCH more like it!
