I do have several copies of the keystore (UTC) file in addition to knowing the password and all that. The wallet I used was just called "Ethereum Wallet" and "Mist". I guess the developers have labeled this stuff as "deprecated" and they no longer support it. I originally got it from github.com/ethereum/mist/releases.

Can I just import my keystore file into a new, modern wallet and gain access that way? Like I said I've been out of the crypto space for a long time and forgot almost everything about it.

It's been so long since I've looked at anything crypto related that I've pretty much forgotten anything I learned from back in 2017-2018 when I started to dabble in mining. That being said, I have some ETH in a desktop wallet that doesn't load any more and I have no idea how to go about accessing the the ETH stored in my wallet. I've spent a couple of hours trying to resolve the issue but every solution I've found has yielded no resolution to my issue.

When I try to run the latest version of Mist it gives me a "checksum mismatch in downloaded node!" error telling me to install the Geth node version 1.8.23 manually. When I try to run the Ethereum-Wallet.exe it just loads forever and doesn't get anywhere. I've tried the numerous guides you can find on Google on how to resolve this issue but I've had no luck.

Any thoughts?

I backed up my original bios and after some more digging around found a custom bios from several months back from BBT so I went ahead and loaded that bad boy up and went from just shy of 22 up to 27.9 / 28 mh/s. I may look for some additional tweaks here or there. My average power draw dropped a whole 20w and it is running 1 degree c cooler. I'm not too sure how much better I can really expect out of it so I may just let it be. It looks like the GPU clock was lowered to 1200 from 1380 and the memory was bumped up to 2100 from 2000. Fun!

I try to research as much as I can before posting silly questions, and I have an idea of what the answer might be but here it goes anyway.

What I've got going so far:

• MSI RX 580 8 GB w/ hynix memory w/ stock settings GPU @ 1380 mhz, memory @ 2000mhz
• Running windows 10 pro updated to latest version
• Using genoil ethminer version 0.12.0
• Mining on nanopool
• Using blockchain drivers from Aug 23, 2017 (version 17.30.1029)
• Card has an average power draw of 128w and runs around 60c

Start.bat set up in the following manner:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

ethminer.exe --opencl-platform 1 --farm-recheck 200 -G -S eth-us-west1.nanopool.org:9999 -FS eth-us-east1.nanopool.org:9999 -O mywalletaddresshere

As soon as I set all my windows performance options, disabled windows update, etc. I installed the latest drivers and my jaw hit the floor when I saw that I was only getting slightly over 18 mh/s mining ethereum.
I looked into the matter and ended up downloading the latest blockchain drivers and was a little relieved to see nearly 22 mh/s after installing those. I spent around 4 hours last night learning how to properly bios mod the card but I have yet to do that.

Is that the next logical step? Hit the bios and then start playing with timings and voltages or is there something I should try in between that I'm missing?

I've finally got all my hardware up and running, bios updated and all that jazz but I've yet to hook up my first rig to the internet. I searched through some threads, most with complaints about windows update and I'm wondering what the current opinion is regarding updates on a fresh system. Should I go ahead and let this thing update to a certain point or do I just want the whole deal disabled from the get-go? Running windows 10 pro.

Alright living room it is. Thanks for the replies! 

Whichever room it ends up in is the one I won't be sleeping in for sure.

So I can't for the life of me make up my own mind right now where I'm going to be putting this 9 gpu rig I'm building. I can either put this thing in my living room or my bedroom. Here are some room details that I'm weighing the pros and cons of for mining this winter.

Living room

• ~700 square feet with an attached kitchen space
• largest room in the apartment more air circulation
• 3 windows that can be opened or closed as needed
• 2 doors, front door and balcony door w/ in and out traffic
• thermostat for the whole apartment is in this room

Bedroom

• ~100 square feet
• no thermostat
• low traffic
• 1 window that can be opened or closed as needed
• poor air circulation

I'm thinking that putting the rig in the bigger room would be better from an energy standpoint during winter. There is more space to heat, more ways to get air in or out and the thermostat is there. There are several things to consider but my brain is fried at the moment and I'm very open to opinions since I'm still new to this and not all that smart to begin with.

I have 7 of the MSI RX580 Gaming X cards and I'm trying to design my own little shelf / frame to put them on. What have you guys found to be a good amount of spacing for these cards for better temperatures and would you suggest mounting them in a vertical or horizontal fashion?

Am I correct in saying that a rig like this looks to be properly grounded assuming it is plugged into a grounded wall outlet?

Mobo is grounded through the 24 pin connection to the power supply connected to the wall?
GPUS are grounded through their 6 pin connectors to their power supply connected to the wall?

I'm trying to figure how I'm going to set up my rig so I've just been looking at the various ways people have their rigs housed and considered something of this nature.

The ATX 1600w supplies are super expensive but I found a reasonably priced 2400w mining PSU which has at plenty of 6+2 pin connectors to power my 7 RX580 cards and their respective risers. I have a spare 600w ATX PSU which I'm thinking about powering the motherboard and everything else with. I'm just not sure if I'm going to be blowing something up by running things in this manner. I'm assuming that both power supplies need to be turned on at the same time which I considered doing through a surge protector. Or could I get away with turning on one and then the other and if so what order? Does it even matter?

I do plan to expand to the motherboards maximum potential at some point and I was looking at some of those 2400w server PSU. I'm still just getting my foot in the door at this point though. I likely will not be dual mining initially.

Current rig parts are as follows:

2 HyperX Fury 4GB DDR4 2400MHz 1.2V
7 MSI RX580 Gaming X 8GB
1 Asus B250 Mining Expert LGA 1151 Motherboard
1 Intel Pentium G4560

I still need to get a power supply, some risers, and some storage to boot from. I've used a few online calculators based on what I have here
and I'm getting numbers between 1200w and 1400w for power. I've found so many different numbers on what it takes to run each RX 580
card varying from 150w to 300w or more per card so I'm not sure what to go with for those. I've done several searches here and whipped
my hair back and forth several times before deciding to bother you all with one of these posts. Thanks in advance for any suggestions.

Nicely done. There goes all the stuff I've been seeing telling me I need more than 4gb ram and a decent CPU for that many cards in a rig. Is it stable so far?

What processor are you currently running in your rigs if you don't mind me asking Smilee? I just grabbed one of these boards myself.

I've been doing some reading and can't find any obvious advantage of using a Kaby Lake processor over a Skylake processor for a GPU mining rig when combined with the B250 chipset from intel. Are there features of Kaby Lake that I would want to take advantage of for a first time mining rig build?

Should I concern myself with getting any more than 4gb of ram? How about ram timing and frequency? I've seen people say that you want "X" amount of system ram per video card and that timing and frequency can be important or irrelevant depending on what you're mining but that information was from 2015 and further back.

Hello folks,

I'm currently selecting parts for my first mining rig and I would appreciate any assistance in this endeavor as I've not built a computer since 2004. This will just be a fun project for me to work on with money that would otherwise likely be gambled away at a casino. I've been searching and reading the forums here in addition to checking out youtube tutorials on building rigs but now I'm ready to get something of my own going. I'm constantly reading up on this stuff trying to get up to speed. I would like to start out focusing more on Monero and then branch out to other things once I get a bit more comfortable.

MAJOR work in progress list:

7x MSI Radeon RX 580 Gaming X 8GB (I have these already, impulse buy on a good deal)

1x ASUS B250 MINING EXPERT LGA 1151 Intel Motherboard

This isn't much of a list yet but that's why I'm here. As for the CPU, RAM, and PSU I'm totally undecided. I've seen a lot of recommendations to just go with the cheapest CPU that will fit the socket and something similar for the RAM. On this particular motherboard I didn't think I'd need more than a single beefy power supply, but again I'm uncertain since I've yet to even pick out all the parts. Since I already purchased the cards I'm hoping to get some insight on how to best build around them.
