As long as it's working and mining, why worry about it? As long as there is enough free resources on the system, memory speed is irrelevant for mining.

Powered USB risers use ~45-50W each. A SATA connector is rated for 54W, which is near the limit and a concern because of the constant draw at near the limit on the connector from a mining rig. That being said, many like BBT advocate the Sata to 6-pin connector included with risers is a heavy duty connector that can handle the load without a problem. To be safe, I use dual sata to 6-pin adapters that spread the load over two connectors instead of one. https://www.aliexpress.com/item/Deconn-SATA-15-Pin-Male-to-PCI-Express-6-Pin-Dual-Video-Card-Adapter-Cable/32584991290.htmlThere are also dual molex to 6-pin connectors. https://www.aliexpress.com/item/4Pcs-High-Quality-2-x-Molex-To-PCI-E-Power-Adapter-4Pin-4-Pin-6-Pin/32759205876.htmlI use 6-pin PCI-E risers. Three thicker wires that are designed to spread a higher 12V load instead of two used by molex and sata connectors. The 6-pin risers also use four capacitors for a more stable current flow compared to the three used by the molex and sata risers. The good ones also come with a voltage regulator to prevent spikes. Just remember to never power more than two risers per SATA or 4-pin Molex PSU cable MAX. Using more more than that, you are overloading the rail and can damage the PSU, cables, connectors or all of them. |

All other software , including wattman seams to work best when the P1 to P6 are disable for GPU and P1 / P2 for Memory, using 1 profile at min/max . Allowing GPU to run only 1 state like that it has no oscillation, would that be a solution ? Of course in idle you have a high power consummation, but no miner should stay in idle with the GPU's, or default settings of GPU could be reset before quit script.
Thanks,
Is any third-part software able to manage voltage with blockchain drivers? Undervolting and Power Limit adjustment works for me with Afterburner Beta 16 in Windows 10. RX 570/580 and 480 cards. |

The AMD Relive Windows drivers are compatible with both cards for sure. On Linux, only if it's a GCN 3 Tonga series card R9 285. If it's a GCN 2 Hawaii series, R9 290/290X, R9 295X2, R7 360, R9 390/390X card, then the Polaris RX series AMDGPU Pro Linux driver isn't compatible GCN 2 or older cards, which use the Linux Catalyst drivers.

Anyone else using the xmr-stak miner? Looking to start mining monero with my AMD cards but want to make sure i pick the right miner.
The XMR-STAK-AMD miner was ~15-20 H/s slower than the Claymore miner on my RX series cards. I also couldn't get the XMR-STAK-AMD to work for my HD 7850, that works with Claymore. |

Thank you for your guide. Can you share your OC setting on rx 470/480 ?  With the Claymore miner I used the same settings I used for ETH, 1150 MHz core 2000-2075 MHz memory and get between 725-775 H/s on RX 570 and 480/580. The XMR-STAK-CPU miner also gave me a 50%+ improvement over the over cpuminer-opt miner on an i7 4770 to ~325 H/s. Do you have also problems with 1 GPU going down several times a day. I use ethos with sg miner and nano-pool, same settings as for ETH and getting around 750 on RX580. It could be that card can't handle the same overclock as the others, causing it to hang from memory errors. I have cards with Hynix memory that have a 1500 MHz strap mod and are fine with a 2075 MHz overclock. Other cards with the same memory I can only go up to 2020 MHz before there are memory errors. Try reducing the core 10 MHz and the memory by 50 Mhz on the card that's crashing and see if it helps. It could also be from undervolting too much. |

The RX 570 4GB at less than $250 is the most profitable (new) GPU, with the quickest ROI, you can buy.

Ethereum has a somewhat stable base of miners and thankfully this is benefiting other cryptocurrencies that are primarily mined by GPUs. However, ETH proved to be more beneficial to early miners and some still believe that it has potential for another rally. So while it doesn't mean other coins aren't more profitable in real time I think that more people are mining to hold ethereum.
Why would you do this when you can mine another coin to buy Ethereum? Mining other coins until I have enough to cash out, to then buy the coins I want introduces more variables and fees. Mining the coins I want directly allows me to better predict how may coins I can accumulate. Which since I'm not planning to sell, is my goal. The most profitable coins ATM are usually the ones with the highest variability in difficulty and price fluctuations. Unless you have a farm that allows you to accumulate enough coins quickly to then cash out and buy the coins you want, IMO mining the coins you want directly is a better long term strategy. Even if ATM it's showing slightly less profitability. Which also means it will have a lower difficulty. |

By using only a limited number of variables that affect profitability, mainly difficulty and price, IMO mining calculators are too focused in ATM profitability and limited to be useful in showing what you really make. Miners that tend do best mine coins they believe them and hold for the long term. Also the ETH block reward wont be reduced until the next fork planned for the end of September.

For Monero you better buy AMD. Best Nvidia miner is XMR-STAK-NVIDIA, also for CPU, but it's only for Windows. For AMD best hashrate has SGminer, but I recommend XMR-STAK-AMD, I like it much more, it's based on Wolf's Miner. Claymore is worst option.
Thanks! Very easy to complle on Arch Linux and getting ~325 H/s with an i7-4770. I was only getting ~200 H/s with cpuminer-opt. |

Can we say upcoming (scheduled) forks/releases will increase block time values too? In that case, one should also expect price increase under normal conditions.
The fork that will undue all the ICE Age difficulty changes and bring the block times back to 15 seconds is planned for September 17th, before the next programmed ICE AGE changes scheduled to happen on September 24th. What changes scheduled to happen on September 24th? will effect to miners? If the next fork is not pushed before then, another programmed difficulty bomb and block time increase will happen on September 24th. https://www.youtube.com/watch?v=R_943As7WMg&feature=youtu.be&t=341There was another dev meeting today. Updates to follow. https://www.youtube.com/watch?v=PQjeAZyL2_wAt the ETH dev meetting yesterday it was stated the earliest the fork would happen is September 22nd and the latest would be October 27th. So it looks like the next ICE AGE difficulty adjustments and block time increases will still happen as programmed on Setember 24th. https://www.youtube.com/watch?v=PQjeAZyL2_w&feature=youtu.be&t=3430 |

Care to enlighten us where these lowered price RX 570/580 with TONS of availability are hiding? LOL Newegg has actually RAISED the prices on RX cards by about 10-20% over what they were a month ago and is completly sold out except for overpriced open box cards. Another thing we learned from the Scrypt GPU run-up from 2014 was GPU prices were quick to go up, but slow to come down until long after mining profitability was non-existent.
There is a key difference in the way you worded it versus the way he did. "Tons of availability" versus "availability improving tons". You can improve a bunch and still not be at a 'good' point.... As a matter of fact I would agree with him that aviailability is improving quite a bit. A month ago you couldnt even source AMD cards and now companies are finding that we can buy a few hundred at a time again since the mining SKUs went into production. Semantics and mining cards aside, the end result is you still can't buy RX 570/580 retail cards in any quantity and prices have gone up. |

There is a limit to how many GPU chips can be pumped out by AMD and Nvidia due to LIMITED FOUNDRY CAPACITY on the production nodes those chips are made at.
They are also competing for that capacity with OTHER THINGS, like AMD CPUs and Samsung smartphones and Apple smartphones among MANY OTHER high-quantity selling items.
Keep in mind that ONLY AMD makes the GPU chips for AMD brand cards, and ONLY NVIDIA makes the GPU chips for Nvidia brand cards.
It's NOT up to the likes of EVGA, Gigabyte, Sapphire, ASUS, MSI, et cetera, as to how many cards they CAN make - if they don't have the GPU chips, they can't make the cards.
Gamers have been able to buy cards - they just didn't always have the option to buy low-cost midrange cards for cheap the last few months. I suspect that gamers "moving up from the 1070 to the 1080" due to shortages of 1070 cards and gouge pricing had a lot more to do with the MINOR availability and pricing issues of the GTX 1080 than miners have had, and it's noteable that the pricing of the GTX 1080 ti never moved noticeably even though availability got a LITTLE spotty on occasion.
BTW - this is also why Bitmain (and others to a lesser degree) have been often OUT OF STOCK on miners - they are SMALL FRY compared to the big boys, and have a much harder time getting ANY access to foundry capacity at all on the current "state of the art" nodes they're mostly using for the current miner generation.
Contrary to your assumption, they CAN'T just "max out their production" because the chip makers are ALREADY running flat-out and have been since the 14/16nm nodes first hit production status (less a short interruption of TSMC when their current-node factory got hit by an earthquake and lost ALL production for a couple months or so).
One additional factor for AMD - they got HAMMERED a few years back when the Litecoin/X11 GPU mining craze died, because they sold too many cards into the craze only to have the market dry up BIGTIME for a good year after that collapse, due to oversupply of cards on the used market. They seem to be trying to avoid that to SOME degree this time around by (1) encouraging their AIO partners to come up with "mining specific" cards that won't drag the market down for "real" cards much if at all, and (2) NOT ramping up production to crazy levels (even if they COULD) to try to keep up with the short-lived demand at the cost of the long term ability to KEEP SELLING CARDS once the current demand dies back down again.
One more point to keep in mind - demand seems to have ALREADY leveled off or dropped some due to ETH (and ZEC and some degree the other GPU mineable altcoins) having major profitability drops over the last couple months, pricing has already dropped a LOT vs the peak and availability is starting to recover quite a bit as well. NVidia is still seeing some elevation on 1070 pricing (and probably on 1060 pricing as well) but it's not CRAZY high any more, 1080 pricing is pretty much back to where it was in Febuary before the craze hit, and RX 570/580 card pricing has dropped a LOT over the last month though it's still elevated, while availability has improved a TON vs a month ago.
The craze isn't over yet, but folks are obviously starting to have second thoughs now that the potential for "2-3 month ROI" is dead and there appears to be some potential for "never achieve ROI" on the horizon with the ETH plans to move to POS actually ROLLING this time around.

A chart can show you anything you want it to. That chart shows the "impact" (what ever that means) of the ICE AGE difficulty, not the actual change in difficulty caused by the difficulty bomb, which is what the OP chart shows. The change in network difficulty from the difficulty bomb yesterday caused the actual difficulty to go from ~1.75 TH to ~2.25 TH or a ~28% increase in block difficulty. |
