Is there a way to move the Mist wallet to a second hard drive without losing anything? Right now, its installed on my C drive (250GB ssd) and since I haven't synced it in many months, I no longer have enough room on the C drive.

I suppose there's no way to recover a password right? The 3ETH i have sitting on my drive since 9 months ago that turns out to be worth $700 now is stuck until I figure out what I used lol. And I absolutely remember the guide said to write it down too lol.

Anyone have experience mining with multi-PSUs? I've got two in my existing setup, (one powering system + 2 cards, one powering 3 cards), and the 3-card one turned off last night locking up the system. I'm thinking it might be related to the power-on board addon I got (links a power molex from PSU1 to PSU2's 'motherboard' power cable to turn both on at once), but not 100%. If it happens again, I was just going to use the paperclip method to leave it on all the time and see if that fixes it. Thoughts?

For the record, 5x 1080TI's humming along like a champ.

I used to have a few rigs with 2 PSUs, I used add2psu boards. Paperclip also works fine.

Yeah, that's the doodad I've got. Just seemed strange that the rig locked up (saw mining drop off via nicehash) and when I went to check it out, the internals were fine but the external cards were all powered off. If it happens again I'll yank the psu board and paperclip it to see if I can narrow it down.

As a side note, how many rigs? Did you have to expand electrics in your place to accommodate or are they just spread out among the circuits?

I actually used the delayed off dongles to cool down the cards on a shutdown. Just turning off the fans and having the equipment heat buildup is horrible for the gear. Also you probably already do, but use powered risers. Those shutdowns can happen if you overload your motherboard, if it doesn't fry.

I was spread out amongst the circuits + I had quite a few unused slots in my electrical box which were put to good use. I had at most just under half a dozen rigs running 4 to 5 cards. I preferred running self contained 4-5 gpu rigs on one 1300w single rail psu, but also had dual 650/750w rigs when the 1300w PSUs were out of stock.

Understood, and yeah I have powered risers. I didn't like the idea of using the mobo SATA ports for power so I'm using ones that are USB for data, and SATA power from the PSU for power itself (along with the needed PCIE connectors), seems to work well. At present, there's only 2x cards in any way connected to my mobo aside from the 3x USB connectors heading into the PCIe 1x ports, so I'm not expecting to have some catastrophic event.

I had to go 2x PSUs because each card needs an 8 and a 6+1 (so 10x PCIe connectors total), as well as not having a massive PSU available for the PSU I wanted (Seasonic Prime Titaniums, the ones very very well reviewed here a month or three back). Other than the one hard lock I haven't had issues with them yet since I built it on Thursday.

yes. mist finally supports this via a command line switch, --node-datadir=[path]

for example mine is on drive N: as i have a dedicated ssd for blockchains. here is whats in the Target field in my mist shortcut:

"C:\Program Files\Mist\Mist.exe" --node-datadir="N:\Ethereum"

my eth blockchain is 54 gigs.

When I setup Ethereum Wallet 0.8.10 on a different machine, I noticed that it downloaded the chain much quicker than expected. It turned out it only require about 22 GB vs the 100+ on my primary system. I was using the same wallet on the primary system but the block chain had initially downloaded using Geth (or whatever the command line tool is called).

On the primary system, I went to the AppData\Roaming\Ethereum folder and deleted everything but the keystore folder and I then launched the wallet again and this time it also needed 22 GB before it was synced.

Ethereum Wallet has a way of leaving behind blockchain bloat. You have to clean it out every so often.

I do work within a few hundred meters of a nuclear reactor. I should probably keep an eye on them.

But must be much cheaper. The gaming card can be sold once mining stops being profitable or a better cards comes along. This mining card will go to the trash then. So assuming that I can sell an RX570 for $80 1 year later said mining card should be as much cheaper at least.

In the end this is just to prevent massive flooding on ebay and so forth limiting sales for NV and AMD further down the line.

Maybe it can be also used as accelerator and therefore it might be interesting for people who use GPU for e.g. rendering or similar tasks

Yeah, it'd have to be *really* good at mining to get around the resale issue. I'd rather buy a batch of 1080ti's again that I can resell in a year or two for 50% than something that mines 10% better but goes in the trash. Hell I'd rather take somewhat of a loss than add to the landfills, honestly.

I recently picked up a 1060 on sale for $150 at Microcenter. Stock speed is about 18.5Mh/s, and you cannot mod the BIOS. But a few clicks in afterburner lets you push 22-23 Mh/s for about 90W. Seems like a good alternative with the shortage of RX cards. Mining something is better than mining nothing. I ended up picking all 24 cards they had left in stock.

540Mh/s. About $100 of profit per day. 36 days to break even. Those 1060 miner edition cards better be really cheap to compete with that.

How much would 570 or 580 cards get?

check your pci-e connectors into the pwr supply. I had this same problem and couldn't figure it out for the longest time. I switched out power supplies and it hummed along fine afterwards. I couple months later i was removing cables from one of the pwr supplies and noticed that one of the cables wouldn't disconnect from the psu. turns out that the connector was melted internal (i.e. bad connection over time and either the gnd or the 12v was drawing/sourcing to much current).

Wow, nice find. Even for a 3GB one, that's a steal of a price.

I'll triple check 'em but they should be good. It's been running fine for about 36 hours now so I'm hoping the crash was a glitch. I had issues with it crashing more often when I had the bios set to PCIE 1.0 (was testing, trying to resolve a separate issue) but since setting them all back to 3.0 they've been fine.

Most RX 580 are about 23-24 Mh/s stock for 150-160W. A successful VBIOS mod can knock down the power consumption to around 110W and push 28-30 Mh/s.

The problem is that there is a shortage of RX 580/570 cards. 1070 cost too much when the 1060 3GB offers 80% of the performance for half the price. Those 1060 3GB Zotac cards are still on sale if there is a Microcenter near you,
