Easy way: Power all the risers directly from PSU 1 which is powering motherboard - Card aux power can come from other PSUs.

I ended up using one of the USB risers which lets you totally separate the GPU power supply as the only link to the motherboard is data.  Plug it and worked first time.

Only down side is there twice the price,  But it I had got this from day 1, I would have gained 4 days mining, sound would have paid for itself.

Hope this helps

2,5 Mh -> 24h of mining -> 0.016 on my balance -> cashout -> still 0 on my btc wallet.
Not recommend, middlecoin much better.

I was going to post this here, but it was a bit lengthy and may get lost/ignored/shouted down. Whatever. I blog as a hobby, sort of like aTriz and nearmiss run Hashco.ws, so I wrote up my analysis of the recent performance. Bottom line: I'm not saying nearmiss/aTriz are doing anything shady, but either their coin selection algorithm is somehow busted or there's something else causing Hashco.ws to consistently choose under-performing coins. The pool is jumping around alt-coins like a jack rabbit on speed, and virtually none of the selected coins seem to be delivering the expected returns. That's not even mentioning the 42 Coin rounds that keep popping up (and keep failing to outperform LTC). Ugh.

The goal is (or should be IMO) profits that are better than mining LTC, and looking at Coinwarz/Coinchoose there seem to be many options that are hitting that mark. Or perhaps stated better: the goal is to mine the most profitable alt-coin, so something other than LTC or BTC, but again there are many candidates that have been consistently above LTC during the past month. So if that's true, why are the coins selected by Hashco.ws somehow getting us less than half the profits of mining LTC? Is Coinwarz lying about profitability and Hashco.ws is getting mislead, is Hashco.ws just getting (really!) unlucky, or is something wrong with the coin selection algorithm? Or maybe something else.

I'd love to see the problem fixed, because I'm lazy and all I want is better returns on my investment. Hashco.ws used to provide that pretty consistently; since the hack and rebuild, I'm not sure I've ever seen us match let alone clearly outperform LTC. That's bizarre...and Middlecoin hasn't been any better that I can see, which is equally bizarre.

We need basic functionality asap guys... it's been over 2 weeks now.  You guys have responded well, but the progress has been slow. 

We don't need a solution. The only solution is go convince the most people to mine themselves.

Solutions are centralized.

This is the free market and we're doing fine.

So, go to the options page and tell 'em not to trade your mined coins for BTC.  (That option isn't available right now because of the reworking of the entire site.)

There is nothing requiring you to have them sell all your coins.  you can have the directly deposited to your wallet.

How long did you guys have to wait for the email to arive?

We are planning on tonight baring no setbacks! 

We want the new portal up as fast as you all do! Just gotta make sure everything is 100% before releasing.

I couldn't register because it displayed "INSERT command denied to user 'node'@'li58-8.members.linode.com' for table 'users'".

We'll be posting a simple tool for people to use, allowing you to login with your credentials, at which point it will send out an email verification link, including your current balance and payment address the site has for you.
