Ethermine actually pays out weekly regardless of balance. It's a mechanism to mitigate risks associated with a Nicehash type theft.

Edit:
Actually, only if 0.01 ETH or higher:
If your unpaid balance is greater than 0.01 ETH and you have not received a payout from the pool during the last 7 days your account will be paid out during the next payout round, usually after 5 - 10 minutes, independent of your configured payout threshold

Good to know. Thanks for posting.

Elfear, you must have something like 600MH/s? I'd say as an individual even that's quite high. It's really low for Ethpool though. It would have been ok with 600MH/s on Ethpool back in early 2017.

I'm a little less than that but ya, I'm definitely one of the minnows at Ethpool. Every time I'd get close to a payout I kept telling myself I needed to find another pool but then real life kept asserting itself. Kicking myself now though.

What's considered the best pool to be mining with currently? I have about 400MH\s at the moment.

I've been at Ethermine for a while now, pretty happy with theem overall. What's the deal with Ethpool? Why do you need a higher hashrate?

Got my dedicated rig more or less up and running in a bench test environment (more like basement floor), just one card at the moment, but once it's proven I'm going to move the other card from the temp (gaming) rig to this one, then close it all up, and rack it and it will mostly be out of the way doing it's thing like any other server.

For now I can more or less leave it at that but my plan is to put in some 200 CFM fans for better cooling and design a temp based fan controller that will be able to drive those fans. They are 2.5 amps each! lol. The case can fit 8 cards but with how hard it is to get cards and at the prices they go for when they are available, I don't see myself get to that point any time soon. Hopefully at some point things will get better.

Man, the fees on Coinbase suck. Those bastards took a $1.49 commission to sell $20 of Ethereum!
If you have a Coinbase account then you also have a GDAX account since Coinbase owns GDAX. You can log in there with your same username and password, and instantly transfer and funds to or from Coinbase at no charge. In GDAX, you can set a limit order to buy or sell (if selling, set it for a penny or more higher than the current price, or a penny or more lower if buying) and your transaction will have zero fees. Now there's no guarantee it will happen immediately, but that's the tradeoff for getting to set your own price and pay no fees. If it's just a penny off, you will usually get a buyer very quickly due to normal market fluctuations and that buyer is the one who pays all the fees. You can also transfer to or from your associated bank account from GDAX and that is free too.

Use GDAX.

Even the taker fees are low. You aren't going to hurt yourself much with market buys/sells.

Ethpool is a Pool-based Solo mining, if that makes sense. The way it works is you must reach a certain credit level before you get paid a block. Yes, you have to wait until a block is made. If you solo it yourself, a system that makes 1 block in 4 months may depending on luck, sometimes get paid in 1 month, but sometimes it might take a year. By pooling it they reduce the variance.

The problem is when your hash rates are low. What happens when difficulty is increasing by leaps and bounds every day? Then the credit required will keep increasing. Then the percentage you have before it can be paid can actually decrease.

OK that's not worth the trade-off any longer. Thanks for explaining.

I use ethermine as well. Ethermine and ethpool are actually run by the same group, just different reward systems.

Officially got 2 cards going in my new rig now. Just need to unrack my old SAN to rack the rig, reconnect the old hardware in my gaming machine to put it back how it was, and I can be ready to just consider this set and forget.

Only thing I noticed though is risers don't seem to stay very snug inside the pcie slots. They fall out rather easily from the slightest bump of the case. Is there a way to keep them in there better? I'm scared that overtime from various vibrations it may work it's way out and short out the motherboard. Almost tempted to hot glue them in place but I can't really easily get a glue gun in there because of the case design. The PSUs are over the motherboard.

Red Squirrel,

some risers are secure, some are not. Minor manufacturing variation.

You could get this: http://cryptomining-blog.com/tag/3d-printing/

On another note, I just received this today: https://www.ebay.ca/itm/NEW-10pcs-1...502466?hash=item33ca9b3942:g:e2UAAOSwak5ZvKCC

My MSI RX 470 Gaming X doesn't have VRAM cooling, so I ordered it. It has Samsung memory but it doesn't matter. Better cooling > VRAM vendor. Stable memory clock went from 1915MHz to 1990MHz. Actually, I'd say its more stable at 1990MHz than at 1915MHz. The profile is so low, that it can squeeze beneath the tight spot below the main heatsink, which is why I ordered it.

Also have a XFX RX 470 that has a "custom" VRAM cooling on it. I took apart a DVD-Drive that wasn't used, cut metal pieces, flattened it, and put thermal adhesive on it. That card is more stable too.

Those clips look interesting. Might have to consider that. I ended up just rearranging the USB cables in such a way that it pushes down a bit on the riser inserts so hopefully I should be ok.

Decided to rack it tonight. Didn't bother making holes to screw it in, it's not like it's really going anywhere, it's sitting on the L rails. So this is officially done and operational.

Now I can passively start looking for more GPUs if by chance I run across a good deal. But think I'm going to wait it out and see what happens. The shortage has to end at some point, hopefully.


Fits like a glove





The back is kinda bad as I originally was going to just have 3 fan holes but it was easier to mount the PSUs and motherboard facing back. Next custom case I will design it differently and more open. Probably do a motherboard tray that slides out, and the back cover will just be part of that assembly.

Overall quite happy how it turned out though. I will work on a fan controller for the front fans that can work via case ambient temperature, then swap those out for the more powerful ones I have which are 200CFM each. I also need to figure out how to get the card fans to run at 100%. According to my UPS I'm drawing 400w between that machine and my workstation, as they are both on same UPS so not too bad. I will need to get a bigger UPS when I start adding more cards.

+1 Looks great.

Skimmed through that twitter post, along with the replies.

Looks like some infighting amongst employees at MEW.

Has anyone figured out how to get the blockchain to sync? I would much prefer to just do my transactions locally if I can. Is there also a web interface you can install on the blockchain node to make transactions easier?

You can install Geth and Mist wallet. The problems I had with syncing I had before are gone. Now it syncs just fine. First time sync you'd want to enable fastsync option from CMD prompt.

Yeah I've had geth running for about a month. I even did fastsync. It "finished" (cur block matched latest block) but I don't think it's actually done since when I check balance it still says 0. The disk space usage is also only like 40GB, I think it should be closer to like 500GB. It does seem to be increasing over time though so just going to let it go and see what happens.

For trying to get myself out of this Ethpool nightmare, could I rent hashpower at Nicehash and direct it to my address at Ethpool until I complete the block?

Apparently, what happened is that someone who was brought in to do the MEW site awhile back finally jumped ship and formed their own company/site - MyCrypto. For whatever reason, this person decided to hijack MEW's Twitter feed and rename it. Someone thought MEW had been hacked. Hilarity ensued.

Are you syncing to an HDD or SSD? Even versions of geth prior to 1.8 can sync to an SSD, or potentially to an HDD if you use large --cache settings from the command line. Allegedly geth 1.8 fixes a lot of the problems with excessive writes to the storage target (which were kinda hard on SSDs, mind you). I have yet to test it myself.

Regardless the latest Ethereum Wallet should sync okay for you. You need to have the wallet file in the correct directory for geth/Ethereum Wallet to find it, though.

Syncing to a raid 10 array, though it's a VM so there is some overhead I guess. But disk IO is not pegged, nor is bandwidth, it's just the process seems to just be slow. Just going to let it go for now. I created a wallet but for now I'm just putting the UTC file in MEW to access it. Not really the best way though and they even recommend not to do that. I will probably keep the funds in that wallet for the time being though. Maybe by the time Ethereum hits the $1,600 range again it will be synced.
