My Compac runs @ 312.5MHz with 1 HW error maybe every 2 days. Decent USB charging hub that is supposed to provide up to 2.5A per-port groups, 7 ports for total of 60W. It's also feeds 2x of Sidehack's (Gekko)  2PAC sticks

Yes, even with a fan blowing on them they are quite warm but then again, seems mining ASICS love high temps.

61 THs is certainly a fair bit of hardware but keep this in mind: It will still probably be a very low chance of 'winning' a block with it.

I run on CKpool (not solo, that is for my Lottery Sticks) currently with 208THs. Since Feb 2014 starting on EMC with 14GHs, unntil they shut down last year when I then pointed my farm exclusively at CKpool. Around 2/3 of the income was diectly fed into always growing the farm.

Blocks found to date by my machines: 5. Think the last of three I hit on CKpool was mid Jan and prev one before it was in Sept, 2016 when I was running around 160THs. Being in either the EMC or CK pools the whole time many many many BTC earned over the years. More than enough to pay for the equipment and other goodies. Even before the last halving I'm positive running Solo would *not* have paid the bills much less financed expansion/upgrades.

During that time many blocks hit *were* by folks running under your size. Thing is, ja they do not get the full prize but -- who know just when they might get a hit? At least being part of the pool they were earning BTC the whole time running what they have...

Looking at the most recent 3 or 4 heavy hitters on CKpool who each seem to hit a block or 2 every week give or take you need over 1PHs to stand a chance of regular hits. The fact that *they* are in a public pool has to tell ya something...

Search Home Depot website or whoever for 'Attic Fan' There are ones made just for this with brackets to mount to the wall studs around your vents. Uber reliable because they are made to be put up in hot inaccessible areas.

Ya know what? As much as it kills me to say it but so far I am pleased as punch with the Avalon's I've picked up and gotta say -- I'll pass for now. This is coming from someone who got his 1st s1 on March 14, 2014 and have gotten >95 Ants of all flavors since then so that is not easy to say. Reason: Quality of the s9 and R4 miners.

My s9's from batch-1 through 22 so far have been great as have 2 of the r4's but my 3rd R4 lost a board after just 24hrs. Reports abound of s9 and R4 issues and truth be told, Bitmain blew it with those miners.

Is the T9 better/more reliable? Maybe, but for now Bitmain has lost their monopoly and I for one am glad for it.

In the US actually it is UL/CSA (Canada) and NFPA code that must be followed.
Anywho, one question that comes to mind is this: If your current panel has no more room, will it also have to be upgraded  to one with bigger main breaker & bus bars to feed the sub panel? How about the utility line feeding the house? If the main needs to be upgraded for higher current service then the 2nd panel probably becomes moot because a new panel will have more slots for circuits...

^^ is dead on! In North America you will have either a NEMA 6-15 or 6-20 for respectively a 220v 15A or 20A outlet. 110v outlets are NEMA 5-15 or NEMA 5-20. The layouts are non-interchangeable to prevent serious mistakes when plugging things in.

Cords for those are not hard to find online. The PSU end are IEC-13 and wall socket end most likely NEMA 6-15 which can also plug into the 20A socket (but not the other way). Of course using a 220v PDU in a way solves that issue because most PDU's use IEC outlets so the cords would be IEC male to IEC female.

Now, if the sub panel is being fed 220v then you DO have the choice of having it wired to feed for example say 2x 220v outlets or 4x 120v outlets because the 220 lines (with wired neutral) can be split into 110v circuits in the subpanel.

I gotta side with sidehack on this.

Having outside funding (share owners, contributors, whatever) even when fully informed of how this business works (Timelines? Huh? A BFL exec had something to say about that...) and the real risk involved still means they *are* going to expect and press for some sort of timeline to be met.

Considering what Sidehack can produce is tied to what chips BitFury sells to him and more to the point -- when -- I would definitely foresee grumbling from a financially-involved peanut gallery.

Private funding is a much harder row to hoe but it affords immense flexibility when critical components, in this case chips, cannot be counted on to be available when planned.

Those particular ones are not PCIe connectors. Same general family yes but not the correct ones.

The site shows the 3mm-pitch (pin spacing) version with a 5A rating and max wire size of 20ga -- too small.

The correct PCIe connectors as shown on https://estore.heilind.com/45559-0002/MOL45559-0002.html are 4.2mm pitch,  actually a 9A rating and up to 16ga.... Even the data sheet linked http://www.molex.com/molex/products/datasheet.jsp?part=active/0455590002_CRIMP_HOUSINGS.xml clearly states that is is PCIe (tm) and what they are for.

Just another reason that when it comes to large undertaking like 1,000 cables, unless you already have the know how, equipment, and time  to do it right, DIY is not ever really an option... Far better to pay for them pre-made by someone who has already done the homework and investment involved.

As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.

On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v  for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?

After futzing around with 2x of the 2PAC's along with an original Compac just plugging them in 1-2-3 I was unable to run all 3 at decent speed without at least 1 stick dropping out. Looked inside the hub and found ^^ so...

Put one 2PAC on port-2, the other on port-4 and the Compac on port-6 so each stick has it's own 5v regulator. Now the Compac is back up to its usual 318.75MHz and the 2PACs are running 175MHz 225MHz giving a total of 65-70ish GHs pointed at solo.kano.org. Lovin' it

No idea but if they do odds are it will cost more because any importer/reseller has to make money and that comes from their markup on reselling wire or other products.

Just ask Weico. On the website they do advertise international shipping but no doubt if shipping to the EU there will be VAT to be paid... That said, the cables certainly are a business expense so I assume your country lets it be a tax write-off no?

And I still think it would be faster/cheaper to just get the cables from Sidehack....

And are not the threads on the Neptunes and Titans filled with many pics of fried connectors? Molex says 8A max per circuit so with 3 pairs that is 24A total @ 12v nominal = 288W max for the connector. *Can* that work? Yes, for a while at least especially with 16ga wires to help carry away heat from the connector. However, it is certainly not a good idea for a designer to EVEN THINK of blatantly ignoring the mfgr specs....

Probably is. as Weico naturally has cross-references to most of what Belden and the other major mfgrs make. Difference is we don't pay for the distributor markup

They are more than happy to mail you some samples to verify the wire characteristics before placing a large order.

As I posted ^ the thinner insulation usually means the wire is semi-flexible and has thicker strands in it so verify the strand count. For 16ga hookup wire 26/30 (26 strands of 30ga) is good and flexible.

Yes.
The only 'difficult' part is sorting through the specs you want as they make many different kinds of and often specialized wire and cable. Generally just standard flame-retardant 300V 80-105deg-C PCV hookup wire is fine for low voltage work in dry, oil-free areas.

Usually the thinner insulation's are found on semi-flexible wire made of fewer but thicker strands of copper. Look for something like Weico's # 3016 http://www.weicowire.com/image/pdf/hookupwire/UL1007%20SPEC.pdf which has 26 strands of 30ga copper in it so is rather flexible.

For the number of cables you want and the amount/cost of the wire used you must pay attention to these details...

Weico is not a reseller - They are a manufacturer of wire just like Belden, Carol Cable, and Alpha who are the major makers of wire/cable for the world. With them you know exactly what you are getting. Only difference is that Weico also does direct sales vs using only distributors.

AWG or CM only apply to the wire core(s) diameter and has nothing to do with the insulation. The wire ref'd above all meet UL and CSA flammability standards within their voltage and temperature use ranges

Jacket thickness only affects voltage rating and and durability.  As long as the voltage rating is good and you are not abusing the wires (crushing, abrading against edges, etc.) thin jackets is fine. Aside from that, the number of strands matters and can affect price as well as the wire stiffness with fewer/bigger strands (eg MTW or building wire) being stiffer/cheaper than hookup wire.

Also when specing cables: we assume Female for the miner end but is the other end stripped/tinned or terminated with Male or Female PCIe plugs?

Was a scam -- more like sheer business incompetence, jumping on the Pre-Order as normal biz bandwagon, then trying to hide from the resulting Shit Storm..

The debacle of Bitmine.ch is what killed them. AMT/Josh HAD chips by the bucket load but because AMT's boards were licensed 'made-in-USA' versions of the same boards Bitmine tried to use.... No hope of them really working.

I was brought in by AMT to do Forensics on some of the different version hash boards and in a nut shell: they were designed by idiots with no clue to proper PDN or thermal design... Was sent a test bed based on the few rigs AMT had released to the loudest complainers (which as they quickly died and often let out their Majik Smoke made things far worse regarding PR...) and out of 12 boards most were dead within 2 weeks with only one lasting almost a whole 6 weeks.

Was also one of a literally handful of folks who *did* eventually get a 1.2THs A1 rig from AMT: 6 mo late and made in Shenzhen by InoSilicon's contract builder using Joshua's stock of A1 chips he had shipped over. Pretty much identical to a Dragon. I ran that thing for almost 2 years with zero problems before retiring it.

@ Sidehack re: wire
My fav source is http://www.weicowire.com/index.php?route=product/category&path=184_50_187
Good pricing and excellent delivery time for most types. Amazing how fast one can go through 5k-ft spools eh?
