This worked for me.
Updated three out of four AMD rigs to 1803 and was able to flash the RX 570's using Atiflash (opening command prompt in admin mode and flashing using command line).

This works flawlessly. Just make sure you open CMD as an adminstrator so everything you run is as admin and it will work perfectly. Atiwinflash graphical kind of sucks because it doesn't give much information about devices and only shows 2 devices but running this with ONE device connected ensures there will be no mistakes as to what flash is going where.

USE THIS. Do not look past this post because if this doesn't work for you, you did one of the steps wrong or used the wrong flash. Opening CMD as administrator is a must.(you right click over cmd in cortana and tell it to run it as administrator).

I have NO idea why Windows up and decided to crap on the ATIWinFlash Utility with the latest version of windows THAT MS WILL force you to update to. I guess a shady driver it doesn't like without you running as absolute admin? In any case, it's a bit of a pain to unplug cards and shifting stuff around but it works and will not brick as long as you use the right rom.

Oh in my case, I flashed it in a full slot. No clue if a riser is any different but it shouldn't be as the riser has access to the same parts of the card for updating the rom as a full pcie slot does.

You know, I can't thank you guys enough for all your help!  I'm planning on having two 240v/30amp lines run to my finished basement. I'm currently running a 13gpu rig on an Asrock 110 but I have a 3 tier red fanned empty stand begging for an Asus B250 to come up for sale for the real price (200-250) and not the stupid 800$ price.

The only problem then is the fripping RX 580 8gb shortage I keep running up against. I bought a PowerColor Red Dragon that I'm waiting to see if I can get it to 29mh like all my other 580s.

So since I have a 200a box, I have 200a? I just don't want to assume anything.

As for my BBS, it was called ßiff's ßßs with 30 nodes on PCBoard. I ran about 5 nodes per computer(with 4 cd roms per node) with a server but the 100a service in the house was PEGGED already with a pool/hot tub/central air etc etc so I needed to upgrade to 200a.  MAN was life good once internet email showed up with batch sending/receiving versus live two way communication. I still miss Trade Wars 2002 and Barrons. Damn good days.

Okay this one is confusing. I used to live in a house that had 100amps. I ran a BBS with a bunch of computers that needed more amps. I had to pay to have our local power company to come in and step us up to 200amps. Was that just a question of upgrading the board to have enough spots for 200amps or did they upgrade the wire to the house?

It comes in at 240?  Well WTF has everything been done in 120 if 240 makes so much more sense?

I have a bunch of Miners I'd love to get that are 240/1200watts.  So that would only be 5amps?  How many watts would each line allow?

As I said I have a straight run right into the back of drywall and a bunch of open circuits on my 200amp board.

Here's a question. Would I need an electrician to find out if 200amps is actually coming in or is there any easy way to tell other than the fact they used a 200amp board?

Thanks for all your time explaining this. I just want my stuff done easy and safely and quickly.  It is all of our duty to generate as many bitcoins as possible to keep the Chinese from taking over the Bitcoin world with their evil intentions!

Oh yes, I'm totally doing that.  Going to run two lines from my board because there's an unfinished part of the basement about ten feet away from just a simple piece of drywall surrounding the finished part of the basement.

SO, what does taking 2 240v lines from my power do to my 200amp service?  Is it less or more than the regular 120v/20amp breaker most rooms are on?  I would REALLY like one of you to like wire your electrician brain to the net for me so I can steal how power works from you. =)

I have 120v 20amp service. I need 220/240 with 1200 watts.  Can I step the current up using a box off Amazon or what can I do?  I've always been confused on what stepping does because I was told 220/240 requires less amps than 120v for the same power needs?





There are 2000w versions as well but if I can get more off the circuit, I'd prefer that. It's in my basement so I could have an electrician run another line from the board too if better?

Thanks!
