It shouldn't matter as when you ask for a higher difficulty it counts as a multiple of regular shares. I asked for 1500 difficulty shares which would give me credit for 3-4 shares when i Found "one" share.

As a side note.... Like you, I too am part of the ' 2x 15A circuit split miners' with my 3x 5-card 7970 rigs. On each 15A circuit, I have an APC XS 1300. I am still testing efficiency/overclocking etc....so right now, 15 cards all running 1.025V / 975mhz GPU / 850mhz MEM. Looks like this... Check your sockets on those apc. I used the same for my miners and it was slowly melting them. They use very low temp plastic. I switched to smart ups XL with proper plugs and have t had an issues.

I threw a ~300 mhash machine up yesterday on solo by accident and it hit a block in the 2 hours it was running. That's the only block I've found soloing in 2 years.

There is no perfect way. As soon as you make one someone else wind find a way to break it or work around it. If its accessible in any form. Someone can break in.

Yep the number 1 thing is get the three little shiny VRM up between the gpus to stay cool. Use the best TIM you can find. I have tweaked both of my 5970's using the stock fans to run at 900/900 on air and keep those VRM under 100C at 1.125V. That's the bottleneck. If they get anywhere near 125C they cut the power and the card throttles. Keeping them below 100C will greatly increase the life of the cards. Run gpu-z go to sensors and watch the VRM temps. Above all else if you can keep the vrms cool you can overclock to your hearts content. If you look at the vddc current it'll be 60 something amps on a good overclock. If you see little lines/gaps and not a solid red bar your card is throttling.

Can anyone just post a quick comparison of the hash rates of a 6990 vs 7990?
If you assumed no over clock and full 7970 speeds it would get about 1100 mhash. There's very little chance of it overclocking near where a single 7970 can go, to 1200mhz or more. It's going to be a very toasty card. If you could get to 1200/1200 it would get about 1400mhash. A 6990 stock gets around 700 mhash. 800 with overclocking.

That is realistic. I've been pointing 1/2 of my power at p2pool. I get between .9 and 1.2btc per block. I was one of the top 10 miners. I should be able to get between 4 and 5 btc per day. Lately it's been about 2, 3 on a really good day.
Um... if you expect 4 to 5 and you instead get 2 to 3, that isn't a 3 times difference. I also think that day to day luck is too variable. Look at least at the last week's luck. Right, but comparing p2p vs my other half on a regular pool I would have made triple what I did at p2pool. That's why I ran half of my miners in each place. To make a real comparison,not a guess. P2pools luck/variance sucked terribly or something else is very wrong. Even with merged mining it doesn't even out.

I dropped 5.4 gh on him, seems to be holding up pretty well aside from a hiccup at midnight last night.

I left too, I can pull 3 times what I was making on p2pool almost anywhere else.

You can also buy ghosts in a can from Ebay, but come on. Zombies, alright I can believe that. Ghosts? Who do they think they are kidding...

Pretty sure all Ammunition has to be shipped Ground. Can't go Air from what I recall. Does USPS even do shipping for Ammo? Or do you have to ship via UPS and other commercial shipping companies? When I order from sgammo, cheaperthandirt, and a few other places, it always comes UPS Ground.
It has to go ground as ORM-D

If you get paid PPS who cares if it goes through P2Pool?

That's cool. The problem with blockchain.info is that it includes unconfirmed transactions and orphans in the balance totals so it is WAY off.

Try spendbitcoins.com Jeremy is awesome. I've swapped several hundred coins for amazon gift codes through him without a hitch.
His site seems to be broken in Firefox right now though. Use another browser if it doesn't work after hitting submit. You should get an email instantly that confirms the "order". The gift code be emailed from amazon when jeremy wakes up ( he's on Australian time )
sweet dude thanks! does he give good rates? I have seen guys on here selling 500 dollar gift cards for like 400 worth in BTC look, he gives the latest mtgox rate, no fees.

Or for someone who mined a ton of coins early and can afford to "waste" them on FPGA or asics or whatever without real cost to them. The buy in cost is killer. Long term is useless if you don't have a powerful setup and be able to stay on the bleeding edge long enough to break even. even now that gap is widening between the hobbyists and the professionals to the point where unless you are perpetually investing returns you won't make it long. I've paid for my 5830s and 5850s many times over. I doubt many will see 3-4 times the cost of the next big thing. FPGA or mini rig or asic unless they are willing to invest at a loss long enough and hard enough to drive the little guys out and essentially carve a niche out.

University here blocks TOR and BitTorrent the simple solution is to get a private encrypted VPN. ~1BTc or $5 a month and you can do whatever you want without any traffic shaping at all. Full bandwidth. It's even better than when the ports were "open" because no one else is using it.
VPN is too important to be blocked my most ISP or schools.

It's still hard to imagine that any competent company didn't have an offline backup. Even if a encrypted copy of a db were shoved to a FTP or Dropbox or carbonite or skydive or any number of free hosts. it's just good business sense for any real business to do backups to another location. It's basic IT principles. General fail all around here.
