Wow.  Just wow.   

NO SHIT, SHERLOCK.

Really? All those NMC that keep on appearing in my wallet from Eligius must be a figment of my imagination, then? 

Even that's starting to show signs of becoming less profitable.   Multi-coin pools are pushing up the difficulty on all the altcoins.

At the moment I have 4 GPUs doing about 1500kH and they're bringing in more BTC than my ~180GH of SHA256 ASICs.

There's plenty of piece of software available that can monitor miners and notify you if something dies.  cgwatcher is one that instantly comes to mind.

Other pools have email notifications, but you pay 2% fees for that privilege.  Eligius is a fee-free pool for miners who can monitor their own miners, and don't get their knickers in a knot when stats die or a payout is 10 minutes late.

It's possible, but it's like putting a Ford 6.2 V8 in a Prius.  It's possible, but you're basically rebuilding the Prius from the ground up to put a V8 in it.

Correct, it doesn't. 

This question is unanswerable - it depends on the PSU.

Any word on the HEX16A2 support, Neil? 

My little TL3020 blew up (it didn't like trying to run 5 HEX16A2 boards via the USB port).  I haven't been paying attention recently, everything was just running for months until the magic smoke got out.

So you can't find Slush's thread?

Hint: On your keyboard (thats the thing with all the buttons with letters on), press the button marked "Crtl" and also the button marked "F".  That'll bring up a find box.  Type in "Slush", and press the enter key (it's the big square button near the right side of the keyboard).  Your internet will show you the thread.  Click on the link and you can post there.

It's basic computer use, I wonder why you're trying to mine bitcoins when you haven't even got the basics of using a computer figured out... 

Try a real computer.  The Pi is a toy with a rubbish USB interface.

Paper clip is fine.  NO need for anything else.

If you've got a bank of dead ASICs, then your PSU isn't good enough.  Simple as that.

At 5GH I'd be looking to mine some of the alt coins in hope that they go up in value, or use a profit-switching pool.

Ooops, failsafe.  And so it begins, again.   

You need to find your sweet spot of core to memory ratio - it won't be the default speed, and it'll be different for every card.  I just used CCC to overclock.  You also want to be running at intensity 13.  Temp target is too high - the 280X throttles around 70C.  These are based on a 7950, but they are not the same!  I've mine set to 65C temp target.

I had serious issues getting my R9 280X working, I was only getting about 580kH with mine.  In a last ditch attempt downloaded GUIMiner-scrypt, set it up so it produced a batch file, which I use to run cgminer 3.7.2 - I now get 710-715kH.  It's default settings for the 280X work well, and once I tweaked the sweet spot, it worked a treat.

You're trying to mine with a toy on a shit pool.  There's your two errors.

1035.49634139 BTC are ahead in queue, putting this user's payout after a 41 block delay.

*sigh*

Bitcoin miners use more power than USB Flash drives, printers, keyboards and the like.

Power supply isn't strong enough on your hub.

You've a budget that big and you couldn't be bothered to do a little research?  A few hours in this forum would tell you everything you need to know.

Therefore, I submit you're talking bullshit, you don't have a budget of anything, and you're just trolling.
