Even a laptop running flat out, while charging the battery will likely use about 65W - there's still something going on...

Use stratum.bitcoin.cz:3333

Wow!  414W for one card?     Seems terribly high.  I'm running a 7950, 7850, 6970 and a 4.5GHz AMD FX and I'm only using 790W.

I'd be expecting about 300W for that rig, unless I'm missing something?

This.  I moved back to BTC for the summer - 21C outside, all windows open in house, computer room was sitting at 34C overnight when mining LTC!    Stays below 28C doing BTC, and saves 200W at the wall.

I thought you needed Windows 8 to run more than 5 cards...

Sapphire HD6970 @ 75C
Asus HD7850 @ 74C
Gigashyte HD7950 @ 69C

All cards in a well ventilated Define XL R2.

Just pulled the HD5870 which ran at 92C with fan at 100%.  Saved 150W at the wall too.  Fan is OK and heat sink is clean.  TIM replaced recently.  I think it's just f**ked.   

My 7950 does the same, but it's only once a week.  It's running at default clocks.  It's also a Gigashyte (it was cheap).

I've never needed dummy plugs?  12.4, 12.8, 12.10, 13.2.....Windows 7, Windows 8....6 different ATI cards from a HD5870 to a HD7950....

I don't understand why people think they need them?

$312?  Are they renting a car and driving it to your house, plugging it in and setting it up for you as well? 

Hmm...joining a pool run by someone who doesn't even know what protocol he's going to use, and can't spell it either, doesn't really inspire any confidence.

I thought this is the way slush's worked?  If you have a dodgy internet connection, maybe a plain PPS pool would be better for you?

If you're Crossfiring for mining only, you're doing it wrong.

I have an old PCI SCSI card in the cupboard.  Would it mine Litecoins too? 

I ran for a day on itzod, and it worked out a similarly feeble reward to slush's.  Bitcoin mining sucks for GPUs now. 

Up to 78% in half an hour.    Happy thoughts, happy thoughts.  

I run similar - FX8320@4.4GHz, 16GB RAM, 256GB SSD, 6x120mm fans (Scythe Gentle Typhoon), HD7950, HD6970, HD5870, HD7770 all off a 1000W Zalman PSU that I got used off eBay for basically nothing.  The Zalman's fan barely spins, and it runs cool.  It's drawing 800W from the mains doing BTC, about 900W doing LTC.

I think your PSU was just a bit crap to blow up like that.

Over priced, under performing junk. 

Anyone buying a card that does 200MH/s for money must be sniffing glue.  With Bitcoin difficulty it'd take forever for the card to make it's ROI, especially considering the amount of power these things use.

The 4870X2 uses nearly 300W of power to do 200MHs.   A cheap 7770 for the same price will do the same MHs and only use 80W.  And it'll have a warranty.  And it won't sound like a snow-blower.

This.  I could pay half that, get a device that mines at twice the speed, and allows me to play games as well.  Oh, and heats my house in the winter. 

Block Erupter is far too slow and far too expensive. 

I just came back to mining bitcoins from litecoins.  I should have been getting 0.04BTC a day.  24 hours later I've got 0.01 unconfirmed.   Crap. 

I'm really regretting moving back to BTC with this luck.   

Another query - I use the mining_proxy from slush's, but I'd be happier if there was a mining proxy that did failover.  I used pool failover on cgminer, but when cgminer is running through a mining proxy, it doesn't fail over when one of the pools craps out.  I use the proxy to keep rejected shares down due to a lumpy internet connection.

So, mining proxy with pool failover?  Or am I missing something.
