you can check out my website, its cryptominingtalk.com and its mainly for people asking the same questions you are.  I just posted a page on a new 6 gpu 570 rig I built.  Other than that, cryptolovers list is a good start.  Keep in mind that you have to play with what is available to you (hardware).  So maybe 6 gpu's is too expensive or too hard to find, and a 5 gpu rig may be better.  it depends.  I suggest a 570 over a 580 due to power consumption, but that depends on your electricity rates and if you are dual mining, etc. 

its all good finally.  just took some time.  your email may have been blacklisted or something.  they will reply to your support ticket, its just long.

5x570 msi armor and 1x asus strix on a msi z170a sli board, 900w dual mining, 160/1450mhs, win10.  Not bad.  I havent pushed them at all, core clocks are either 950/1050/1125 mem 1925 to 2000, 0.84v to 0.96v.  I find 570s to be more resilient than 470s for some reason.

So this is a motherboard from hell.  I made a post on my website to help people with it.  The info is sourced from the official 570/580 thread, big thanks to atanas012 (i believe it is him who came up with the driver solution).  Check it out here:  www.cryptominingtalk.com/6-gpu-rx570-with-z170a-rig-build/

And now you can stop bashing your head against the wall.  God damn the z170a...god damn it.

thanks everyone, I guess i'll wait till next week to see this figured out.  I've always liked bittrex over polo, and even now I see red flags at polo - although - my withdrawals there have always gone through.  I'll close this thread, its good to have feedback - no trollbox and all.  Even the slack was kinda empty (being sunday).  cheers

thanks, makes sense I guess, since everything else with the site is fine.

Besides the ZEN thing, I havent heard a word from them anywhere.  bitcointalk forum thread is pretty much dead.  Support does not answer emails (so far), and transactions (at least for me) are pending.  Emails are not sent either.  Anybody else have trouble withdrawing from bittrex ?  I have an old account, and i'm withdrawing a small amount of btc, so nothing related to the account or the btc could be the problem IMO.

thought ?

hmmm trying to withdraw, but no email sent.  i tried 3 times and sent an email to support.  we'll see, im not too worried though so far.  I'd get my coins out of polo if I were you guys lol, not saying there is a problem....but dont take chances.

edit:  still no answer from bittrex, starting to get worried.

hahahahha sometimes its the smallest things  

yup ! 

Looking for one 30 amp PDU and maybe also a 20 amp PDU, 240v.  Like a tripp lite 1230 or something similar.

no offense to anyone, but selling ASIC's by ROI numbers is probably standard practice, unfortunately, GPU's and computer parts sell by second hand value.  nice setup, but over 15$ per mhs.  I'm not interested at that price, but you should consider selling the rigs individually, you'll have more luck.  A lot of people here would love to own maybe one unit or a couple.

damn 20 fans thats crazy.  i wonder what your electricity capacity is, over 200 amps ?  I just have a turbo fan type exhaust out the window, moves air really good.  if its at max, outside you can feel it 15 feet away.  gpu temps arent really lower much, but house temp is wayyyyyy lower.

people can't get their money out by wire, so they buy btc and withdraw that.  since everyone wants out apparently, btc will shoot to moon on bitfinex.  symptom of worse problem usually, although bitfinex says nothing to worry about, nothing to see here.

no one seems to be answering your question, so read up on it here for example.  https://www.techpowerup.com/228536/amd-bios-signature-check-re-enabled-with-relive-locks-out-polaris-bios-modders

i'll help you out, if it ain't shady or anything.  what website are we referring to ?

makes sense, thanks for reporting !

I feel people who have norton or other AV's usually have more problems than me, who has none.  how you use the internet I suppose.  Also some people are stupid with computers.  in related news, does the rx570/580 modded bios work right off the bat with the newest drivers, or does it work with the older 16.11 or whatever drivers ?  I havent ordered any just curious about the signature check

Hope so too.  I saw the sapphire 580 nitro 8g comes with 2 extra fans, which is pretty nice.

so i'm guessing you have to do the whole signature check dance for the time being ?
