I would add three more rules to that:

• NEVER run a power supply at more than 80% of rated load for an extended period of time. An occasional spike above 80% is probably fine. Most consumer grade power supplies are not rated for 24/7 continuous use.
• Put the power supply on a dedicated circuit with the appropriate sized circuit breaker, and don't exceed 80% of the rated capacity.
• Use an appropriately sized power cord for the power supply. The nice and flexible, lightweight power cord that came with your low power draw LCD monitor is not what you want to use when plugging in your monster 1600 Watt PSU.

Copy & Paste is my friend, and every thread needs a curmudgeon. 

Yes, but right now Pandaminer is having trouble getting GPUs. This message may help:

https://bitcointalk.org/index.php?topic=1668461.msg19664744#msg19664744

Here, let me read the:

for you. Perhaps you might find the following paragraph on page 8 of the:

of interest. It says, "Clients who have their own mining equipment can host it at Giga Watt at the same hosting prices, with the only difference of paying the following setup fees: USD 20 per ASIC-based miner, USD 40 per GPU-based miner¹¹.

You're welcome.

That's mighty selfish of you, don't you think? sidehack has a life of his own, he's busy guy, and there is a pretty good chance that he is located in a different time-zone than you. You are not his only customer, and you are no more important than any of the other customers he has, perhaps even less so since you haven't purchased from him yet. Try reading the first message of the purchase thread and all the details are usually presented.

I've dealt with sidehack, both via message threads and PMs on this forum. I have purchased a modified S7-LN miner through him, and everything was as advertised.

dafuq?!?!?!

Yesterday I ordered an L3+ w/ PSU and shipping included for $1550 from giga-watt ( https://giga-watt.com/promo/prices ). Yes, giga-watt will be hosting it. Yes I have purchased WTT tokens which guarantee space and power. It will not arrive until 20-September or so but that's OK with me as I can not run it at home (electricity is too expensive here). Keep an eye on giga-watt's web page to see when they have L3+ in stock and buy from them. While you are waiting for the L3+ miner(s) to arrive buy enough WTT tokens to cover the L3+ miner order (see my sig for a referral link to buy WTT). Just remember that each L3+ requires 880 tokens.

There is no way that I'd pay USD4000-USD4500 for an L3+. If I was going to spend that kind of money for a miner, I'd be more inclined to build an open-frame GPU rig with six GTX 1080Ti GPUs and mine other altcoins. You'd probably have an better chance at achieving ROI. And at the end of the day, if you tire of GPU mining, selling off the 1080Ti GPUs will be easy.

I'm in the queue. Earlier today I ordered an L3+ for delivery in September. Process was pretty smooth, though there was a lag from when I used https://giga-watt.com/promo/prices to initiate the purchase until the sales team contacted me. I paid in BTC, so I ended up paying about 0.1 BTC more, but in fiat it's the same price.

Once they contacted me for the purchase it was completed in under an hour.

This is not Amazon, but check on Amazon as sometimes they sell there.

I've ordered a bunch of stuff from them and they are easy to deal with. They also have dealers/resellers in other countries if you are not in the US.

If they are deducting their fees daily from your earnings, one might think they pay out daily.

Go here:  https://giga-watt.com/promo/steps  then scroll down a bit to the Pricing section.

It looks like what you mine is converted to BTC, if necessary, then managed from there.

based on that info, it looks like Canaan has new hashing boards, each with 26 x A3212 16 nm chips on them, so 104 A3212 chips total.

Here's a crappy attempt to guess the 761 hash rate and power use. This guesstimate is based on 741 numbers.
https://canaan.io/product/avalonminer-741/

Hashing:
741: 7,300 GH/88 chips = 82.96 GH/chip
761: 82.96 GH/chip * 104 chips = 8,627 GH

Power Use (low end):
741: 1,150 W/88 chips = 13.07 W/chip
761: 13.07 W/chip * 104 chips = 1,360 W

Power Use (high end +15%):
741: 1,322 W/88 chips = 15.03 W/chip
761: 15.03 W/chip * 104 chips = 1,563 W


Is it true that with auto-adjust enabled on the Avalon741 the hash rate is higher if conditions allowed? If that is accurate, and the Avalon761 has/uses the same feature, then the hash rate may be higher, if conditions permit.

Small USB stick miners, like this one, are more for getting started in the bitcoin mining game. They are mostly a learning tool, but also a way for you to join the community. That said, the miners do contribute to the distributed nature of the bitcoin network. Unless you are solo mining and find a block, which is not impossible, just highly improbable,  they will not return your "investment."

It sounds like they are trying to verify who you are and whether or not you actually did send them coin. So what's the problem with providing them that info? If you don't have it, perhaps that's the problem.

This is the internet, where we can be anyone we want to be, until someone actually wants proof...

Heh, I contacted Giga-Watt shortly after the start of the WTT ICO and asked them if they were considering Avalon miners instead of/in addition to the Bitmain models. They responded within 24 hours and said that they were considering it, but needed to evaluate the miners.

Compaq! 

Geez, it was a big jump, too. Lots of new hash rate coming online.

Hmmm, could have sworn that there were FPGA LTC miners. No biggie. ASICs are where it's at today for sure.


Hmmm, I must have missed the other ones. The mobile vs. standard GPU is yet another trade-off. But, as you said, it allows them to cram more of them into a given space.

The thing about GPU miners is that they can easily be adapted to a new coin that is GPU mineable. Bitcoin went CPU ➜ GPU ➜ FPGA ➜ ASIC. The same for Litecoin. I mined some LTC back in late 2011/early 2012 using older computers and heating a room in my house for a couple of months. That LTC has funded my current cryptocurrency adventures. My only wish is that I had held it until now, but hey, that's life. I have a low-end GPU miner (see my sig) that I use to play with GPU coins. I currently switch back and forth between ETH and ZEC, but can mine any coin that has miner software written to take advantage of my GPU.

GPU mineable coins require a relatively small amount of money and some software smarts to be able to optimize the hashing algorithms to run efficiently on a variety of GPU architectures (there are several different architectures for each of the two big player's GPUs). The end-users will have, or will build, their own mining rigs which can double as gaming machines. The costs to design, build, and sell an FPGA miner at scale (more than just code running on a widely available dev board) are significantly more than GPU rigs, and ASIC miners are significantly more expensive than FPGA rigs.

I like the idea of the PandaMiner machines (custom motherboard with off the shelf GPUs). It was just a matter of time before someone made the effort to do that. Think about it. There are a bunch of people who are building and selling (at a premium) five, six, or seven GPU mining rigs based on consumer motherboards. It was just a matter of time before a company took advantage of their resources to build a dedicated GPU miner.

USB 3.0 is sketchy with the Compac and 2Pac sticks, so try sticking to USB 2.0 hubs. I did some looking around on the aliexpress site and came up with this one:
https://fr.aliexpress.com/item/LVSUN-120W-5V-24A-10-Port-USB-Charger-HUB-USB-3-0-Chipset-with-Data-Transfer/32640377816.html

You can put the two 2Pac miners in the 2.4A USB Hub ports (there are four total data ports) and you can plug the fan into one of the other non-data ports.

It's not cheap, but then his current ports that also pass data are kind of odd and are scarce.

bwahahaha, can't say I disagree, but then I do own multiple machines from the fruity company, so I guess that's an altogether different issue.

Back on topic: @zumpbond2000 do what sidehack suggested and load VH's new cgminer; plug the Compac into a USB2.0 port (they don't like USB3 ports); get a good powered USB hub; get a small fan to cool the Compac to ensure a long life.

Regarding the USB hub and cooling fan, search back through this thread for some suggestions for both. There is at least one other thread for powered USB hubs, too.

This is the setup I use: https://bitcointalk.org/index.php?topic=1173963.2420

Apparently the internet djinn are pleased with something I have done. I pointed my sidehack'd S7LN (~2TH) and my Gekko Compac (~18GH) to the pool and both are successfully hashing away. This is the first time that the S7LN, since I've had it in my possession, has been able to successfully mine to pool that wasn't a P2Pool node.
