What I highlighted was the voltage requirement to actually use the miner. If your in North America, you will need a 220/240v outlet. Most homes with an electric dryer have a 220/240v outlet. Or you can hire your local electrician install a 220/240v circuit. I am not sure about EU/Asia as far as 220/240v availability in homes/residences.
It would seem they blew thru their stock and rebuild (RMA) units once people start talking about this board. My 2nd unit I got was an RMA unit as well. I think a lot of the RMA's were people having issues getting Nvidia cards working and just sent them back. So technically nothing wrong, just people who were frustrated.
Now the question is are they getting more stock? And when.

It looks like the miner comes with a power supply. And according to the spec, it can't be used on 110/120
Product Parameters
Hashrate： 2TH/s（-5%～+5%）
Wall power： 2kW/h（-5%～+5%）
Noice： ≤75db
Fan Speed： 6000RPM
Voltage Input ： 176-264V AC
Connection： Ethernet
Dimension： 310(L) * 180(W) * 280(H)mm
Weight： 7kg
Operating Temp： 0~35 ℃
Or did you get the HS3-SE? In which case you could run on 110/120v, but I would still recommend you run it 220/240v circuit.

Why do you want to use such GPUs? They are mostly useless. Any GPU costs same as much as profit it brings. Try to search AMD RX470-580 with 8GB memory at least. Or may be 1060 with 6 GB.
In another way you can buy 3GB or 4GB GPUs, but you can`t mine the most profitable coins with them.

funny thing. I picked up a pair of AMD Firepro S9000 (6GB ECC RAM) passively cooled gpu's for $175 off of ebay. Popped one of them in to a test rig, fired up lolminer and off and running @ 23 MH/s. They do run hot currently, 74c. So I am redoing the thermal pads and paste on the second card. This card is the pro version of the HD 7950. But it was cheap, and I was interested to see if it would actually work. If anyone knows if I can control voltage and clock speed via parameter setting with lolminer, please post a link to the documentation.

HD 79XX series hashrate dropped when increasing
Dag file, and so they were sold. Although these cards had 3GB of memory, except for the HD 7990.
These cards were very hot, if I'm not confusing anything, then they were heated up to 90 C. After 100 C, my farm turned off.
This is the professional version of the 7950 called the FirePro S9000. They are passively cooled and designed for high density servers and doing rendering/AI-ML type workload. They come with 6GB of ECC RAM as well, so I am mining Ethereum. The DAG generation is actually pretty darn fast around 3000 ms and one I have running has been rock solid at 23 Mh/s at 73-74c with a aftermarket mod from gpumod.com Here are some links to the card.

The biggest draw backs I have found is while 'lolminer' will work with the card, tweaking it seems to be hit or miss if the changes actually happen because the monitoring tools under linux are pretty limited. Oh and that it really does draw about 250w when running.

Re: Is it recommended to use M.2 expansion slots to connect an extra GPU?
It cost $60.00. Try it out and if it doesn't work return it. Amazon has a pretty liberal return policy. Looking at the m.2 to pci adapter its not rated much better. But you have options, so I will leave it at that.

Looking at your screen shoot, the HWINFO for the gpu draw matches what the miner is reporting of 38W (now why it reporting just the gpu pull is another question) and that maybe correct at that moment in time measurement. GPU power draw will bounce as it works. If the hashrate is in your expected rate, then I would not focus on that issue. What some others have pointed out is the memory junction temp is way too high. You might want to look at doing a tear down and redo the thermal pads and paste on this card.

Whoa there nelly, hold on a second. The reason one gets stale/reject shares may have nothing or everything to do with you. Here some questions to ask before you jump.
1. How many and how often are you getting stale shares? Is 1 or 2 every few minutes/hours/days/weeks? Occasionally get a run of stale/reject is normal, the internet is just like getting stuck in traffic sometimes. Something happens and traffic slows down.
2. If I change mining pools do those numbers change? Do they increase or decrease? If they decrease, then it probably on the mining pool side, skip the getting the router.
3. Do I see issues with other internet connected devices (TV/gaming consoles/web browsing, etc)? If so, contact your ISP/Service provider you may have a wire issue.
4. Is my mining connection via WiFi. Well that alone is probably a issue unto itself. But in our daily lives WiFi congestion is a fact of life and can cause latency thus stale/rejected shares.
This is just a few things that come to mind. So before you go spending your hard earned money, make sure that its addressing a valid issue.

Why not just get a 4 to 1 PCI-E x1 riser card and add more that way?

Just and update on Nvidia GPU's and RebTech 8 gpu miner. I recently got in my second one, so I decide I would try to get the miner to work with my Nvidia 1080's and Titan XP. Initially if a GPU was attached, it would not boot or display any video. I was frustrated to say the least. So I started poking around in the BIOS and saw a parameter that I remember from way back could be problematical with Nvidia GPU's and how it maps Base Address Register (BAR). Normally its not an issue with enabling 64bit BAR as most PC's have more than 4GB of RAM. But since these boards mostly ship with 4GB that can be problematical as the board tries to map the memory above the 4GB memory boundary, just something it does. So I disabled it and suddenly when I plugged in my Nvidia GPU I had video output from the GPU.
So next thing was to fire up Hive OS and see if it saw my GPU and if it would mine.

On to adding more Nvidia GPU's and see if it would still boot and mine.
https://i.imgur.com/tmDFYSi.png
So here are the steps I did to get it running.
1. Boot the Rebtech without any gpu connect via pci po
2. When it boots to the device list, hit <ESC> key to enter the BIOS
3. In BIOS down arrow to Setup Utility (last line in the list) and hit enter key
4. The move to the Advanced Tab (right arrow one time)
5. Then down one line to PCI Express Configuration and hit enter
6. You will see 3 configurations on this screen. You want to disable 64bit Bar Support.
7. Press F10 to save hit enter and exit.
8. Power off your Rebtech, and connect your Nvidia GPU to pci port 1
9. Plug in your monitor to the Nvidia GPU, as you will no longer have video out from the miner board when a GPU is connected.
10. Power on, boot HiveOS and configure your rig.[/li][/list]

I will answer with your terms.
full x16 riser are used to build farms on two types of video cards 470, 480, and 4 GB analogs for mining Ethereum using a lol miner and 3060 so that the Ethereum hash rate does not decrease.
Otherwise, you can use regular x1 raisers. This does not affect the hashrate in any way.
for your video card, be sure to use 6 pin raisers, for example

do not use sata raisers

Why are full x16 riser need for 470/480 cards? PCI-E 1x work fine from my experience, is there something that running them in a 16x helps with?
First you need to verify that both of your PSU's are working. If you have 24 pin short plug, test the PSU individually. If you don't jump pin 16 and 17. If they both power on then move to the next step below.
If both power up, then next step is to remove all of the everything from the motherboard (ram, pci cards, drives that are connected.) Clear the cmos and then plug in just one power supply, 1 stick of ram, keyboard and plug into the onboard video (dvi-d port). If the system powers up, then you know the motherboard is good.
Then start checking your gpu's one by one by plugging them into the PCI-e 16x slot on the motherboard. If they all check, then your gpu's are good too.
At this point it comes down to either riser cards and or the pci-e 1x usb cards.
So plan on spending time testing each one of them.

Anyway fees will be near 0 when ETH network will increase by 100x. Vitalik announces it in july.
"Ethereum Could Scale 100x in a Few Months, Says Vitalik Buterin"
Just a speculation.
More like a pipe dream. He has a vested interest in pumping the price. But I honestly don't expect ETH to break 2K and stay above that. It certainly made a lot of people nervous with the bruhah between miners and dev. As for the fees, yeah, even at 100x the fees will still be high, despite what VB thinks. People will pay high fees for priority in the block. And nothing says post Eth 2.0 that devs charge a fee of 5% to 10% for priority inclusion.
With the introduction of PoS, ETH is becoming more and more centralized rather than becoming decentralized. Exchanges like Binance and people like CZ are always willing to control the market and exert huge centralization over the crypto community and this was possibly true when he was willing to do a 51% attack by bribing miners and reversing the bitcoin chain. Nowadays the primary purpose of any cryptocurrency has become a mere speculation, so obviously ETH would shoot up in price if there are more proper developments taking over but on the other hand if there are worse speculations going over and in the process we would be suffering from a bear market. This is why a mineable PoW and ASIC resistant currency like Monero would offer an excellent decentralization while comparing to Bitcoin or a PoS coin like Ethereum.
Ethereum Classic is more or less an useless mineable currency, i.e they are only used for mining and are suffering severe 51% attacks now and then. So probably ETC is geared more towards making money by offering a better mining solution rather than any use cases. ETC becoming decentralized would never make the coin superior to ETH atleast in terms of making profits as ETH provides one among the best platforms on the decentralized web to deploy contracts. This could never be achieved by a centralized chain like BSC but there are still quite a few possibilities DOT might be looking as the future ETH with more scalability and thereby providing similar use cases of ETH.
A mere $5k per coin would place the total valuation of Ethereum at $500 billion, but there are centralized chains like BSC which offers better scalability in deploying contracts so possibly there could be stiff competition for ETH in terms of hitting $5k price.

Exactly. The concentration of ETH's supply among a few stakers (validators) should be a real concern for those supporting the decentralization of Blockchain technology. It seems to me that ETH devs only care about convenience than true decentralization. It's always been about the money, instead of making crypto/Blockchain land a better place. Once ETH becomes a full-fledged PoS cryptocurrency, big exchanges will dominate the Blockchain. I believe that ETH miners will migrate into ETC, making the latter blockchain network bigger and stronger than ever. One thing for sure, is that ETC has been a victim of constant 51% attacks over time. It's hoped that with the ETH 2.0 upgrade, this will no longer become an issue.
Nonetheless, I believe that staking ETH yourself will only be good for making short term profits than anything else. Don't expect to take ETH seriously as the network will become less decentralized over time. ETH will remain actively traded on the market as long as people keep pouring money into it. If you care about decentralization, then I'd suggest you look elsewhere. Mining ETC or even Bitcoin itself might be a better option than staking centralized coins. Just my opinion
As I understand it, and correct me if I am wrong a these points.
- 1. Right now the only smart move if you looking to be a ETH 2. staker (validator) is spinning up a VPS with companies like Amazon/Google/Azure. You are going to want at least 4 9's possibly 5 of reliability and uptime. Because if your down, your penalized.
2. You can't get out right now if want to (phase 0) until phase (1.5) sometime between now and 2022/23? Which means if ethereum is tanking between now and then you lose, on the flip side if ethereum jumps to 4K you can't liquidate either. And you have ask to withdraw (stop validating) so if a number of validators want out, they could be blocked for a period of time.
3. Penalties are severe for inability to participate as a validator in the network. No exceptions give in their documentation for natural disasters (hurricane or earthquake for example) or man made (damage infrastructure due to human involvement). In theory (honestly that is all we have now is theory) a validator could lose their entire stake if a majority of the network decides to take it. It doesn't matter the reason. If a majority agrees your out, your out.
Finally it looks like Ethereum 2.0 will devolve to a few validators (couple of hundred or less) as they purge their numbers over time and via the normal acts of transactions accumulate enough of ethereum in their bank to represent a majority of the vote (which is based upon how much ethereum you have). Note the highlight line from their FAQ. Tell me that isn't an incentive for a bad actor(s) to try and manipulate ETH 2.0 to get 51% of the vote and evict validators and take their stake in the process.
https://launchpad.ethereum.org/faq
What exactly is a validator?
A validator is an entity that participates in the consensus of the Ethereum 2.0 protocol.
Or in plain english, a human running a computer process.
This process proposes and vouches for new blocks to be added to the blockchain.
In other words, you can think of a validator as a voter for new blocks.The more votes a block gets, the more likely it is to be added to the chain.
Importantly, a validator’s vote is weighted by the amount it has at stake.
Why the sudden worry about miners shifting hashing power to ethermine.org? We aren't responsibility for what a pool decides to with the hashing power it has. Same way that the devs are not responsible for listening to the concerns of miners over selling out to corporations so they too can get enriched, even if briefly. What apparently some miners don't know or care to know is that none of the developers pushing this change are miners. None. Their only interest is to cash out and make some money.
Remember it was the miners who generated the funds for expansion, development and pushing ethereum as a valid and reliable crypto currency.

Can someone recommend me a good budget 800-850w psu? Is there any priced around 70eur
Bagge6, if you mine in a place where noise is not a big issue, buy second hand HP server PSUS, which you can find on EBAY, they are cheap and kick ass.Here is an example of a 1200W that can run fine at a load of 850 if that is what you need for your rig:

Under load the fan will get a little louder than a regular gamer PSU so if you keep your miner in your living room or bedroom, it's not a good idea but if your miner is in a basement or garage or something, these server grade PSUs are the best bang for the buck.
