I can get this miner working directly to a pool. however, MiningRigRentals will not connect.

Any ideas as to why?

this in the consol:

win10(win8)+1063+latest drivers
epoch 177-178: work if use claymore with key -eres 0
epoch 179 (~8 apr): work if use ethminer 0.12.0+
epoch 180 (~12 apr): work if use driver 372.54 + claymore with key -eres 0
epoch 181 (~18 apr):  work if use Windows 7 or linux

conclusion: u can use win10(win8) + 1063 + driver 372.54 + claymore with key -eres 0 up to ~18.04.2018 after that only win7 or linux

or u can use win7 or linux now and forget about dag issue.
win7 up to ~ 11.2018
linux up to ~ 12.2018

Please learn the difference between break even and return of investment before making educational charts. Assuming that the price and difficulty stays the same (it won't), the device will pay itself in 43.5 months ("1305 days ROI" in your chart) and after that it will start mining for profit.

Wrong. You can't generalize if someone should mine or not as you don't know how much he's paying for electricity + the hardware.
For most people you're right but there are still enough people mining at profit and not at a loss.

Looking for a ” Miner OPTIONS” configuration for CryptoNight-Heavy that makes the AMD RX580 8GB cards run with their peak performance.
 
Under Windows 10 with SRBMiner these cards run around 950 H/s per card, but in SMOS they end up around 660 H/s in both XMRig and XMR-Stak, so if someone know which setting I need to add to the configuration in SMOS to solve this speed issue that would be great.

hashestohashes - I am unsure how I've thrown mud at another developer, and will fix it if I have. Please point me to it.

... as far as millions, don't we all wish...

I can't speak to the capabilities of others, but I spent a reasonable amount of time on my work (if others can do it faster, that is awesome!) and actually acquired licensed copies of IDA Professional and Hex-Rays ARM32 compiler to support this work, that alone cost $4100 USD plus tax. I also had to import a Z9, which after customs/taxes/shipping cost $4179. So before I even started the work, I was out $8279.

I've also spent numerous hours responding to email inquiries and PMs to provide support for installation, for overclocking, etc. I've spent a couple of hours this past week in 'teamviewer' helping another individual load on 8 machines....

I definitely didn't do this to "get rich". I only hacked this because I was frustrated that bitmain had locked 'my unit' after delaying it 3+ weeks.

Awesome! Thank you for sharing freely and openly.

.... and for the record, any one responding to my post and providing feedback, did it of their own volition. While that was 'good marketing', it was not driven by me and was completely organic.
.... and as far as comments about donations, you can see for yourself by checking the addresses for donation. The only funds sent to those were funds I mined myself during testing, and funds someone sent before talking to me asking to get the full version..

I've updated my post pointing people to you. Enjoy!

I'll stop working on per-hashboard-frequency management that would have worked on every single cgminer based miner Bitmain has released.

To do it, just add 2 more segments to cgminer, code up the frequency management reading functions back from cgminer.conf, then go into the main loop that handles frequency setting for the hashboards, jump the current function into your code, set up the same registers, and jump back into the function that actually sets the board frequencies.
Second, modify cgminer to support updating the frequencies across the boards by not having it restart. To do this, hook into bitmain_ZCASH_reinit_chain, but don't step on the functionility int he check_miner_status() function.

Also, please update the image to support auto-tuning of the frequencies once you have this done so the end users do not have to worry about the clocking manually. Many do not know how to SSH/etc.

Back to my day job!

here's the fees UPS wants:

$189.18 USD

for one unit.. 

The first batch is not yet fully launched, and the profit fell to 8-10 dollars, depending on the cost of electricity.
https://www.asicminervalue.com/miners/bitmain/antminer-dr3
Now purchase orders are set for October 8-15. By this time, the profit will fall several more times and the asic may not be payable.

Those who bought in September will probably earn if they sell it now

Two of mine from the first batch shipped yesterday DHL.

Please don't swear. I got notice of this website on Discord in a miners group. He is clearly talking about a company named "Blocksolutions" and i have looked the EUid yes very strange.. they might changed their domain name between those years?

UPDATE:

I placed my order and it's shipped already Topic can be closed. They are legit.

Bitmain likes to do dirty tricks with SOLD OUT to cause FOMO to save their company from going bankrupt. Nice try bitmain, that worked last year but 2018 is way different.

This shit ain't sold out. Especially with 25 percent added tariff's and a far superior DCR miner comming out from. Whatminer, plus obelisk DCR going online. I would not touch bitmain DCR with a 10 feet pole.

If you want DCR that badly just buy the damn coin. You'll get more units more so than what a miner can ever generate . Crypto is risky enough and mining is even riskier with no reward potential with current increasing mining difficulty and oversupply of miners.

If your the guy that bought a bitmain DCR you just went full retard.
