I miss San Diego climate (lived there for almost 12 years, part of that in the Navy but most of it after I got out) and watching lots of pretty gals in bikinis on the beaches almost year-round.
I do NOT miss the cost of living there.

Modern miners generate the DAG "file" directly on the GPU, so you won't have on on your HD/SSD anywhere.
What the heck are you using that's only generating 2 Mhash on the MINER?

I won't bother testing it as long as it is windows specific.

Drivers for the 6xxx series isn't an issue - 15.12 works FINE on them.
The TERRASCALE is the issue - a lot of current miners are GCN specific and won't work at all with older cards.
78xx cards are GCN - not comparable for mining.
IMO avoid the bloody Relive drivers unless you HAVE to use them - horrible bloatware that do not offer ANY performance improvement (except in narrow cases using the "Blockchain" drivers).

I am in a very similar boat here in Central Florida. I am no HVAC expert but was wording if the following would be possible……take a portion of my existing warehouse and build two small insulated rooms divided by Server Racks. Then use an evaporative cooler set up in a closed loop configuration, similar to the attached diagram. The humidity output by the miners should be low enough for the evaporative cooler to work properly. The server racks would pull cooler air from the room with the evaporative cooler and push the exhaust to the other room. There would then be a duct that connects the two rooms together to feed the evaporative cooler. Am I totally crazy or would something like this actually work?  The Evap(s) should be placed at the input of the "duct", but otherwise that's somewhat similar to my current setup where I am at now. I'm doubtful it would work AS WELL as where I'm at, as the air around here tends to be very dry - but it should help some. DEFINITELY invest in a humidity meter to keep an eye on the RH at the intake of your miners when you try it out - I rarely see anything over 40% RH (and it has to be actively RAINING outside to get close to 50) but the humidity in my area tends to be very low. I don't bother with the "duct" as such - I put my evaps in the "hot output air" area and the output of them pointing at my air intake area. I currently have 2 Brisa "window" type units (BW3004 units IIRC, both bought during "end of season" sales from the local Ace Hardware) stacked on top of each other with some boards for spacing, and enough space that I can add a 3'd one on top if I need it in the future. |

Extension cable usage for the power levels involved on a 24/7 basis = MAJOR FIRE RISK.
Even if you use the uncommon ones that are rated for 20 amp capasity, the connections still get hot.
If you upgrade your breaker box (325 amps might not be an option, I think the options in that range are 300 and 400 for "non-custom" designs), plan to have the power company upgrade your service wiring to whatever they require for that "320 max amps" service.
Your current service wiring might only be rated for 100 amps at 220 vac (breaker boxes are commonly "oversized" 25% or so for safety reasons) - be cautious about pulling more than that, or even pushing CLOSE to that, as 24/7 service REQUIRES the wiring to be derated 20% for safety reasons.

My concern is the large file writes.
See; I have killed 4 SSD's last year by continually shuffling large files from my gopro to my laptop (256Gb SSD), then when home; laptop to server. Sometimes its downloading a 1-3Gb torrent, but I always preallocate space as to relieve strain on the file tables.... But with SSD's over time of handling very large files, you will notice the machine having pauses with a seemingly solid HDD light, but it will always recover... then one day it will happen and never come back... Just dead to system drives now. When it pauses, its like a processing lag glitch.... you don't pick up on it until its already very serious and it takes 15+seconds or more to continue doing what it is doing.
This behavior has happened on business class drives (Apacer), user class drives such as sanforce chipped units.... and in expensive samsung 840EVO black series drives. I have a bunch of them I need to try and hack into the serial port on them and see if I can recover the data..... I lost a lot of important files more than once.... I dont want to have to remove the flash chips, read them in a flasher off the board, then reassemble the image on a pc and recover.... It's a LOT of work, and the NAND readers aren't exactly cheap themselves......
Writing to a SSD eventually kills the memory cells - they have a limit on how many times they CAN be written to, which varies depending on the drive and variations on each individual cell and most drive "manage" writes to even them out among all the cells in the drive, which tends to cause lots of the drive to fail at once when they DO start dying, as opposed to concentrating the writes on certain cells and having a gradual deterioration of drive space (there are good arguments on both sides of that debate though). Mining generally doesn't do a lot of writing to the drive (ETH in the days of DAG file creation on the drive was an exception) so it should be much less of an issue in a mining rig - though Windows usage would tend to increase the issue a little. |

Never said anything about pre-mine. I was reffering to the general attitude to pre-order 3 month in advance. You cant tell me Bitmain needs the money to source parts or do RD
Bitmain does not... but they still do what they did in the past... pre-order and take the money. More than likely Bitmain CAN carry a stock and sell in real time but they don't want to..... I have heard a lot of interesting things about that company and what they do to short supplies and what not.... These guys are competing directly with them so they need to secure funding in advance. I doubt that Bitmain can "carry a stock", as their access to foundry production is pretty limited due to them being a small producer while AMD, NVidia, and the like have foundries booked for MONTHS ahead on LARGE wafer count production runs. As has been mentioned in many other threads before, the very few foundries that HAVE 14/16nm production lines are SWAMPED by demand - and the cost to bring such a line up and into production is bloody expen$$$$$$$$ive and takes quite a while. No insult intended promojo, but you're not exactly a WELL known member - I'd vastly prefer someone that IS well known like phillipma or HaggisFin or even Doogie to review a unit before I'm inclined to trust in it's existence. I'm not sure if I'd count on that list, as I've not posted reviews of "new gear" from new manufacturers before. |

If they didn't have that "minimum 3 units" order requirement, I'd likely have some A4 units by now. |

Yes, obviously AMD GPU meet your requirements for mining ethereum. I have no idea why people suggest you Nvidia for ethereum  If you are looking for new cards, then you can get 470 or 570, these two are good in power consumption. That's the point. But yes, for newest NVIDIA cards (1070ti - 1080ti) also have a good performance on Ethash. At current pricing, the 1070 ti and 1080 ti are VERY BAD CHOICES to mine ETH on. 1070 ti has the SAME hashrate as the 1070 (which is ITSELF a overpriced choice), 1080 ti costs almost DOUBLE a 1070 but only returns about 20% more hashrate - and all 3 cards are BADLY blown away by any RX 470/480/570/580 on hash/$ at recent pricing on the RX cards. Vega 56 mining Monero right now is a very good choice - *IF* you can find one under $500 or so. Supply seems to have dried up for the time being though, and the 64 while it also does well costs a good bit more than the 56 for nearly identical performance - the Vega is VERY MUCH memory limited in Monero mining, so the extra cores on the 64 don't help noticeably. The current price gouging on Vega cards WHEN you can find them at all is making them not so good a choice though - and on anything but Monero they are NOT competative on hash/$ with other options even when the 56 was $449. |

I'd be more inclined to go with the G3900 Skylake over anything Kaby Lake, due to better support across the board. Pricing is VERY similar to the G3930, performance will be a tossup - and that link posted to Newegg's listing for the G3930 also has a G3900 option on the page you can click to for quick comparison. For the price of that ASUS Prime motherboard, you can get the ASUS B250 Mining Expert that has 19 slots and built-in 3 power supply management - the ASUS Prime boards are all VERY overpriced for mining boards IMO. Newegg themselves are out right this second https://www.newegg.com/Product/Product.aspx?Item=N82E16813119028 other than a couple of overpriced "marketplace" sellers, but I suspect Amazon would have sellers with them in stock at a reasonable price for the board. |

I'm confused as to why poolgold was releasing the new version when this is closed source? Unless EWBF runs poolgold?
Because it was NOT an official new release - it appears to have been an attempt to spread a trojan CLAIMING to be a new release. |

Hye, Just watch your vid, how much in total for having mining rig exactly like in your youtube? because seems cant find exactly that nvidia 1080TI you using http://amzn.to/2jwsQI2 ? different with your video ? is the GPU he is using in the video, but like any blower card the cooling is less effective than a good fan-based card like the Aorus or even the EVGA SC. ASUS makes a very similar model if you LIKE the blower cards, and IT tends to be in stock more regularly - and left off the DVI connector for MUCH better cooling airflow and somewhat better temps. Shouldn't be an issue when it's being run at 80% or less of TDP (200 watts on every 1080ti I am aware of is 80% TDP, but there might be a few out there that have a default TDP higher than 250 watts) but cooling on a 1080 ti tends to get painfull if you are pushing the card and it's NOT a good high-end cooler card like the Aorus (the MSI Duke mentioned as an alternate should also have very good cooling). |

Corsair - is iffy, it depends on who is making a specific line for them as to if it's any good or not - and I've given up on trying to keep track of them, since their GOOD lines are mostly Seasonic made anyway (I think the do use SuperFlower for one of their good lines, like EVGA does for the G2).
Thermaltake - I've not been impressed with ever on power supplies, though they make some good cases.
At your quoted prices, the 4GB 570 is probably the best option - it will be lower hashrate but close enough that the ROI on it should be somewhat faster, which is CRITICAL if you plan to mine ETH on them given the very "up in the air on when but being actively worked on" of ETH moving to Proof of Stake.

GRC isn't the only such coin - there is also CureCoin and FoldingCoin and a project that gives out a small amount of Doge for FAH work.
TO be fair, some of the work GRC rewards isn't actually scientific research - like the Moo Wrapper project - but most of it is.

If you are talking about the Zotac Mini models, they have a noticeably smaller cooling setup than almost anything else - so they ARE going to run hotter than most other cards.
All of the ones I have are going into rigs that are aimed at high efficiency, running ballpark 60% TDP - and they run pretty cool at THAT power level.

You can't use a GPU on Board. The slots are very close to each other. To mine coins you need to the minimum distance between the GPU was 10 cm You will still need to use risers. It seems to me that the use of expensive motherboards it is an unjustified waste of money.
Really? Don't tell that to PhilipMA. LOL Don't tell it to me either. 8-P Yes, that motherboard WOULD work for a "3 card on the MB" rig - but plan to use something short in the end slot to allow the middle card to get tolerable cooling. Most of the 3-card rigs I built were AMD based, but I did end up with one rig with the Gigabyte Z270-HD3 (which is a VERY close variant on that board). If you are going to go riser, there are better choices (some of which are NOT as expensive as the quoted ASRock H110 Pro BTC) that will allow 6 or 7 cards per rig. |

You don't want to run PSU's close to the rated the capacity. They won't be as efficient and it will shorten it's lifespan. 50% to 80% of the rated capacity is where PSU will run most efficiently and cool. The other consideration is how many PCI-E connecors you need for all the GPU's and risers. Many PSU's less than 1000W will only have 4 PCI-E connectors per PSU. For 13 RX 570's you will need a minmum of 13 individual 8-pin connectors just for the VGA power. Some cards like the Nitro+ also have a 6-pin connector that may be optional. For risers I use 6-pin PCI-E risers only and connect two or three risers per PSU 8-pin cable using a PCI-E 8-pin to dual 6+2 splitter cable, figure another 5 PCI-E PSU ports for the risers, so in total you need a minimum of 18 PCI-E ports.
Wow thanks alot for that and everything. That has clarified alot for me. I didn't realize you have to run risers off the PCIe ports on PSUs. You CAN run them safely via MOLEX adapters - and there are some with all 3 connections that are the recent "4 cap" versions. The COBOC ones Newegg sells as an example, seen the same design from a few other places. You don't HAVE to run 19 cards from the ASUS B250 Mining Pro to make it worthwhile - the on-board power supply management is nice, and saves a few $$ + is simpler vs having to use Add2PS type adapters. If it's lower cost vs a 13-slot MB, it's DEFINITELY the better choice. NewEgg has a Canadian branch, can't hurt to check them in addition to the other sites you mention. I strongly recommend use of the EVGA G2 supply line over the G1 or the GQ or the G3 - the BALL BEARING fan is going to outlast the "fancy name sleeve bearing" junk in the other lines. I'm not 100% sure on the G2L line - I think it's also ball bearing fan, but the power connections are kinda wierd and do NOT match up with anything else at all. I can also recommend the Seasonic X-series, but those are in very short supply and getting way expensive when you CAN find them any more. |

The Molex connectors on the motherboard ARE for additional power to the PCI-E slots - which is a waste on that motherboard as it IS going to be used with powered risers in virtually ALL cases.
You also don't HAVE to use the 2'nd and 3'd power supply slots if you don't need that many PS (I only run 2 for now due to infrastructure current limitations).
