Surplus server PSUs tend to be the best value and are built very well.
Server PSU's are fine, if you enjoy the sound of a jet engine in your living space, LOL. lol yeah they are pretty loud. You can swap out the mini turbine fans for more efficient quieter ones. A quality high wattage ATX PSU also has a good resale value. Server PSU's are cheap for a reason. There is no consumer market for them other than mining. |

I like the EVGA G2/P2 series because they use a single 12V rail and can deliver >99% of the rated power over the 12V line. Dual conversion PSU's, like the G2/P2 are the best because they convert the entire energy into a 12V single rail and then uses VRM to generate 5V and 3.3V. The cheaper PSU type converts using different taps in the transformer for each voltage and use the 5V line to regulate the voltage, instead of the 12V line like the dual conversion models. That causes voltage instability from not loading the 5V line.

your question is impossible to answer
1. You have to have a wallet per coin type, there isnt 1 wallet that does everything. It just doesnt work like that.
2. What do you mean by mining function? Wallets dont mine. Ever.
Actually like the original BTC wallet, most wallets have a built in solo mining function. You have to set gen=1 in the debug console or wallet configuration file. The problem is it uses the CPU and for most most coins, the difficulty is too high to solo mine with a CPU. The miner also isn't optimized for diffrent processor types, so you are better off using an external CPU miner. |

Hi.Which driver is better to use for monero?Now the miner is running on the Beta drivers for the Blockchain but there are some problems-a lot of rejections,a miner is not showing the temperature of the graphics card
The Claymore Crytonote miner hasn't been updated for the new AMD API that was implemented in the blockchain beta drivers and Relive v17.7.2 drivers. If you want to see the temperature and fan speeds, you need to use the Relive v 17.7.1 drivers. The rejections probably have to do with your overclocking settings or the pool, not the drivers. |

It depends on how many cards you plan having in the rig and how many power connectors each cards requires. The total watts is only one factor. Another factor is number of PCI-E power connectors you need for the GPU's. If the PSU doesn't have all the VGA power connectors you need for the cards, you may need to use a larger PSU with more VGA connectors or a secondary PSU to have enough VGA power connectors for all the cards. Another consideration is when going with a 1500 W or more PSU, two smaller PSU's are cheaper than a single larger PSU.

I have a Sapphire Nitro+ RX 570 4GB. While dual mining UBQ+DCR, GPU-Z shows 140W plus add another 50W for the riser, so ~190 W total @ 1150 MHz core clock, 2150 MHz memory clock with a -96 mV undervolt and -10% Power Limit.
If you plan on dual mining, for 7 cards I would go with a 1600 W PSU. For a dual PSU I would go with a 1200 W + a 750 W or two 1000 W.

Personally I never use the latest CPU's and memory for mining rigs. There is no performance gain and generally it only causes compatibility problems. Especially if you plan on using Linux, which is notorious for not supporting the latest hardware. For my latest build with the ASRock H110 Pro BTC+ I used a Skylake processor with 2133 MHz ram, even though it cost more than a comparable Kaby Lake.

Yeah that's kind of what I figured too but also if it takes 2 minutes I may as well get the speed I paid for. Otherwise I could have just got a Penium & 2133 to save some $.
2400 MHz ram is intended to be compatible with Kaby Lake CPU's, but you bought a budget CPU for a mining rig, not a performance gaming machine. The speed is irrelevant for what it's being used for. Older gen RAM and CPU's are also usually more expensive since it's produced less than the most current specifications. |

I would recommend using cloud mining or some variant of it if you really wish to mine. Considering electricity cost, its unprofitable to mine in most places in the world.
GPU mining, including ZEC is profitable. I would recommend doing your own research and determine what's best for your own situation, rather that listening to random people. |

Mining Ethereum will be no longuer profitable : this is true, but not for these reasons.
PoS will never see the light.
AMD GPU hashrate will decrease more and more.
Ethereum will dump in the nexts month (again and again).
- Actually, the development for the initial hybrid POW/POS release is running as planned. With deployment anticipated for sooner, rather than later according to the developers. https://www.youtube.com/watch?v=PQjeAZyL2_w&feature=youtu.be&t=4100- AMD has already released the Windows drivers that fix the Dag epoch hash drop. The Linux fix is expected soon. https://bitcointalk.org/index.php?topic=2092279.0- My crystal ball is broken ATM, so can't confirm or deny. |

No, the whole PC is rebooting. Like the power goes off, then comes back on.
I know it's hard to catch a pc rebooting sometimes.. Walk away, miss the error message..ha been there. But sounds like an OS issue to me. Mining software normally wouldn't reboot your whole system.. Try and catch that error message and see whats causing it to reboot. Trying to see if the older drivers are stable could rule out any other issue.. One of my 6 x 1080 ti rigs use to reboot my software consistently due to a partially faulty riser.. "Gpu 0,1,2,3,4 stuck.. reboot attempted" Worst case.. change drivers, or clean install of the OS. Mining software or specifically a GPU crash can absolutely cause the system to reboot. In fact it's one of the most common problems in Windows. A GPU can crash from too much overclocking or defective hardware like risers, causing it to hang when communicating with the miner and the miner will reload in an attempt to resolve the problem. In which case the miner will log which GPU caused the hang and restart the miner, or close depending on how it's configured. If it's a hard crash that can't be resolved by the miner restarting, the miner can crash while restarting and cause the system to reboot or freeze. You also don't need to be there to read an error message displayed before an OS crash. That's what the Windows error logs are for. |

I dont think the difficulty will change soon. but there will always be people who get free electricity and put htere miners in that area. Fo those people, they will be profitable all the way to the end.
You don't have tho think. ETH team accounted that difficulty will be increased by almost 50% until the end of the year (September and November are two points If I remember right) and that is not counting additional miners that will increase difficulty even further. That is not correct at all. The main reason for the drop in profitability is the programmed ICE AGE difficulty ramp up that was implemented to get miners prepared for the Casper POS release planned for the end of this year. Which exponentially increases the difficulty and block times artificially as the date to the switch to POS got closer. Now that the move to POS has been postponed for at least 12 months, the ETH developers will undue the effects of the artificially high ICE AGE difficulty and return to the difficulty being predicated by the network hash rate and 15 second block times in the next fork scheduled for the end of September. If they can't push out the fork before the next pre planned ICE AGE ramp up, there will be another difficulty bomb on September 24th, until they release the fork. https://themerkle.com/ethereums-metropolis-hard-fork-will-activate-at-the-end-of-september-2017 |

What miners are running when the system hangs or reboots? Have you checked the logs? Have you checked the Windows error logs?

Actually, whattomine is not 100% accurate. Even tho ZEC and XMR may be higher on the profitability list, whattomine fails to take into account DUAL MINING. ETH can be dual mined with DCR or SIA and that should be added to the profitability calculations. In the end, ZEC and XMR still have more or less the same profit margins with ETH+dual mining.
Dual mining hashrates varies depending on the GPU. Whattomine does have dual mining profitability calculators for ETH, ETC and EXP. You have to click on the 'ETH+', 'ETC+' or 'EXP+' tab at the top of the main page to get to the dual mining options. |

thanks for ask, i have other question. Now i have 2 workers, but in the web page status only show 1, what happen?
Depending on the pool it can take 10-15 minutes for your workers to show up after you start mining. If it's still not showing up, double check your pool configuration. you talk about the settings in browser? or the bat file? the bat file is the same in bouth miners, same pool, same config ahh... the name of worker in bath file true? work1 work2 ... Yes. You should create a worker for each rig you are connecting to the pool. |

The REAL, PRIMARY reason profitablity has dropped over the last 2 months is that lots of miners have been adding LOTS MORE RIGS with LOTS MORE GPUS chasing the same rewards and thus diluting the rewards between those LOTS MORE GPUS - coupled with ETH pricing and block payouts being nearly flat over that timeframe.
The diff increase is a mostly a byproduct of MORE FOLKS CHASING THE SAME REWARDS coupled with the (so far small) ARTIFICIAL increase, and not a direct impact on profitabilty (though it does have an indirect effect).
Ice age on the other hand, so far, has had a very SMALL effect on the difficulty.
The Ice Age artificial increase does NOT affect profitability, only the "more GPUs mining" part of diff increase does because that does NOT affect all miners equally, while the Ice Age artificial diff increase DOES affects everyone equally.
I continue to state it is a stupid concept with no real reason to exist, since it affects all miners EQUALLY and doesn't change the rewards gained from any particular block - it's the dropping BLOCK PAYOUT that is effecting that.
It also doesn't affect block rate over the long term.
Consider Bitcoin, which also uses a difficulty system which has gone up a TON more than ETH has yet the block are still targeting the same timeframe to be issued - it's just SHORT TERM that adjustments get made due to diff changes - and in the case of ETH the "short term" is very short indeed.
You might want to consider looking into ALL of the facts before you call someone else ignorant.
It's true the ETH network hashrate has increased exponentially, which cause the rewards to be diluted by all those mining. But since the ICE AGE effects began back in May, the difficulty is artificially adjusted according to programmed difficulty bomb, not the network hashrate. The artificially high difficulty along with the increasing block times most definitely affect everyone's profitability by slowing down the amount of blocks mined in the same time frame. Less blocks = less rewards = less profit for EVERYONE. That's the main reason ETH is no longer the most profitable coin to mine, since the difficulty bomb on August 25th and not because there are more people mining ETH. Wait until the next ICE AGE difficulty bomb adjustment on September 24th and tell me if has no affect on profitability, LOL. At the current price, ETH won't be profitable to mine AT ALL for most people, until the hard fork scheduled for the end of September that will undue the artificial difficulty bomb adjustments and go back to adjusting the difficulty for the network hashrate along with reducing the block times back to 15 seconds and reducing the reward. |
