ETH staking:

 In the real world, financial instrument yields are tied to some kind of market mechanism. I've never seen an explanation
    for the ETH staking yield of 8%. Also what are the mechanics of changing this yield?

In the real world, 8% is a huge yield, assuming inflation is 2%, net after inflation is only 6%.

I don't believe 6% covers the risk in staking this asset.

How does this square with the fact that the power grid and pricing can be erratic in TX?

From Wikipedia, the free encyclopedia)

I think you have two options:

A) Risky: Go on youtube and absorb all the videos on graphics card repair. If you are lucky they may have your card. There is a set of tools that GPU repair dweebs use.

B) Conservative. Extract remaining value out of this card by selling it as a not working card on some sort of EBAY. US EBAY probably has about 10 guys who buy non working graphics cards. I suspect China and Russia have the same demand

This is my take:

a)Purchasing an ASIC miner is always somewhat of a gamble.

b) Your first very big mistake is not waiting for YOUR electrician to complete the job. The second piece of this mistake is not being patient with anything having do with the installation/operation of an ASIC miner. Until it's reliably running, any mistake on your part blows your schedule and you budget. The key deliverable from the electrician to you is a 220V AC line (insert: with a breaker) with the correct plug AND he/she demonstrates to you the plug is properly grounded and has the correct polarity. If possible I would check the power supply DC output.

c)  Seeing the two loose heatsinks was another schedule pause. If it was me, I would shake the miner and listen to the rattle of these loose heatsinks. If you hear the heatsink rattle then it's ALL STOP. Call up/email the supplier with a picture of the loose heatsinks and a video of the rattling noise. There is no way the seller should wiggle out of this. It needs to be shipped back and the problem fixed.

Here is what I don't get.

 Nvidia must have some insight on the future of GPU mining. Popular thought has ETH POS coming online soon. Why then do you announce

more nerfed GPU offerings? Why go to the trouble of complicating your supply chain since in a few months ETH POS should dampen if not kill off

GPU mining demand?

I'm not a professional engineer, so check with the proper experts.

This is what I have done as a US mining hobbyist.


1) You cannot overload your electrical panel. So the limit is 100 A. This is what unusual about mining in that you will be needing power 100% 0f the time. A panel may have more circuits then capacity but in your case you are limited to 100A

2) This 100A will flow through circuit breakers. Circuit breakers are derated by code to 80% of their rating.

3) A 120v circuit uses a 15A breaker. The total available power per circuit is 1800W x .8 = 1440 watts

4) So 100A/15A = 6.67 systems

1440 W is on the edge

One thing about mining is that you can to some degree adjust the power draw down. If you are a gpu miner you can shuffle cards around operate them at a lower power for the most hash per 100A.

I didn't see this here:

"The HNT website has this: The Helium Hotspot is now sold out for both North American and European customers."

A very rough back of the envelope calculation has about one of these hot spots every 20 miles.

There is an issue with this line of thought, do you maximize the residual value of a GPU? or cook the card? Probably the two best answers to this question are the 480 GB nitro+ sapphire card and the EVGA 1080 ti. Both have held up in value, still do a decent amount of hashing and were not too bad cost wise. The 1080ti is particularly noteworthy because it has/had good mining flexibility.

One other point to note is that higher efficiencies (W/Mhs) are at the lower MSI AB settings. There is a message there.

Additional things to look at.

With a problem card, I get some success with:

1) Swapping/exchanging the trouble maker's riser with a neighboring card or a known new one.

2) Lowering the core clock by about 10%.

3) Update to the latest mining software and card driver.

I would also consider whether you have a large enough swap file.

Comments:

1) You should get 39 to 41 with the 1080 ti card at maximum efficiency.

2) there are 3 pill options, they are all about the same:

a) ogodanETHenlargementpill.exe (Be careful with this one because there are virus infected versions)

b) T-REX Use the -mt 5 setting use the latest 0.19 version

c) PHX 5.5D MUST USE the -straps option. I use 5.

3a) setup:  50/100/-501 to 54/125/-501  As far as I know this is the best efficiency settings (about 150W per card)

3b)   You can run this card full out (100/0/0) and reach 70 BUT the card runs very very hot. This is the Scandinavian option    where you have cheap hydro power and it's zero C in the summer. Requires serious thermal engineering on the users part.
 
4) Use a large swap file.

5) This card is also has a lot of flexibility and can decently mine a lot of coins.

6) You may have to play around with the dag loading.

Appendix:

a) Memory tweak mode (default: 0 - disabled). Range from 0 to 6. General recommendation
                                   is to start with 1, and then increase only if the GPU is stable.
                                   The effect is similar to that of ETHlargementPill.


                                   Supported on graphics cards with GDDR5 or GDDR5X memory only.

I just skimmed through the posts. Apologize if this is duplicate info:

Another way to heat up your miner wiring is to start mining before running MSI or what ever software sets up the cards. If not setup with MSI first, my cards will run full out.

1) The manager(s) of ETH don't really understand that they have a good thing going for a lot of people with POW.

 There is a whole economic eco-system around ETH where people can make some money. GPU CPU manufacturing, MB's, SSD's etc. accessories, utilities, used stuff  etc etc. The barrier to entry for mining is pretty low and the infrastructure requirement(s) is basically just a 120VAC wall plug. Also I would guess that ETH has a better geographical distribution than BTC. I believe Phil said a few years(?) back that some companies could subsidize the ETH block reward because they are selling the shovels during the "gold" rush.

2) BTC also has some strategic problems that ETH doesn't have. As the value of BTC rises, you will have more and smarter people trying to hack BTC because the rewards are so very high. This is a reason I'm not 100% in BTC, because a hack will cause a loss of confidence which is a critical requirement for BTC.

3) IMHO ETH is plugged into the future in so many ways, while BTC is in some sense static. This is a consequence of being a one string guitar. BTC is getting the of attention finally of financial institutions, but at what cost?

4) I agree that if ETH is forked away from mining, that a copy of todays ETH should fork away from anything that negates mining.

Is this the scam that we have been warned about up thread?

Link is fishy. Titled "Medium" to give the patina of respectibility, but "linked" to somewhere else.

Well, the dinkfest continues.

 Four days of mining ETH have yet to show up in my Bittrex wallet. Normally it takes 1/2 hour tops. Sent a note to Bittrex. Is there an issue with the ETH chain?

Best

I also have been getting email questions that fall into the "source of funds" area from Bittrex. I have been with Bittrex since forever.

I have seen big banks drop small businesses with the explanation that compliance costs are larger then any revenue the account generates.

I suspect that Bittrex is doing the same thing at the crypto level. They are weeding out the accounts that don't make money.

Had the same temptation.

Assembled a rig:

H81 MB, 6 ea ASUS Stryx R9 380 4GB cards. About 185 Mh/s @ 900W (Kill-a-Watt P3).

For 900W, cclock 800, mem clock 1500.

This card has I believe a somewhat larger cooler for running warmer and quieter.

I don't recall that this card's bios could be modded.

I also have too many Acorns.

The question is what is the best way forward? I think legal action is a dead end dumpster fire.

The best approach is the "this is the hand you've been dealt approach". I will outline some possible +EV possibilities.

1) Some sort of group buy action for services revolving around the most profitable/useful mining bitstream for the acorn. The developer to be paid in acorns from us.

2) Some sort of numerical accelerator application. If you recall, the original IBM PC's were sold with an empty socket for an add on numerical co-processor chip (which was as large as the CPU chip). Would an acorn plus software have any use in scene rendering applications?

3) Could a FPGA dev kit have any use for the acorn guts?
