Well if I had to pay, power here is 5 cents. $.05/kwhr here. It's cheap. Luckily I can run my farm where I have "free" power and climate control. Aside from maintenance and reinvestment, my mining is pure profit.

Why do you want a Xeon? The extra cores? Why not get a 3930k and overclock the piss out of it? Most will do 4.5ghz easy. The xeons can only overclock by strap which sucks since it overclocks everything.

Something still wrong with the site. No matter what it always returns a blank page after hitting submit.

You can't unlock shaders. You can't change the clocks or memory without a bsod in windows. You can use a 5870 flash to get higher clocks if the card can handle it. There's a risk to brick the card and you'll need another card to flash from dos.

You can use rbe to edit the voltage registers to get a higher default voltage and use cgminer or afterburner to overclock.

How much can you handle? I can drop 1-10gh your way.

Well use newegg.ca

I've got a 5830 that'll clock to 1250 MHz and do ~500mhash. Most only go to 1000 and do 315. 

My 5850 even with a voltage bump only do about 950 and around 375 mhash. Beyond that they crash after a short time. they don't get hot. It's just instability.

My IOcoin never went down. It's still happily hashing away getting blocks and confirmations

When a block is found is it submitted directly to bitcoind network or does it have to be approved by nodes before?

Just seems that lately p2pool is running much worse than normal variance would suggest. 

Run cgminer as failover only

I highly recommend creating the "hacked client" yourself by downloading bitcoin-qt yourself. In the src folder edit main.h and change both to zero

static const int64 MIN_TX_FEE = 50000;
static const int64 MIN_RELAY_TX_FEE = 10000;

compile with the makefile and save it.

and make sure you send more than .1 btc or it's possible the transaction will never confirm.

The way bitcoin is implemented right now, if you have a "hot wallet" to do transactions on, someone can hack it. Any automated way and it's hackable. Bitcoin has to be exposed to the network to send and receive coins and as such there's always an exploit to break in somehow.

If you are a miner or only receive deposits, you can create a wallet totally offline, get an address and deposit coins there and it is secure so long as it never sees the internet.

sign up for an online insta wallet type service

wait 144 transactions past your last balance to be able to send fee free.

send your coins to the insta wallet in some random manner.

withdraw them in a random manner later in time ( over say 1-2 weeks )

that pretty much launders any amount of coins.

The other option is to "sell" your coins to someone who doesn't care, a service or a miner and have them launder them for you and purchase mined virgin coins.

What I've done is to put each miner in a separate sub page so that if one miner goes down it doesn't make the whole page fail to load or take forever to time out.

I also added


to the top to do the auto refresh.

I get about 5-10 mhash a sec more on 11.12 vs 12.1 with sdk 2.1 IIRC

If anyone can figure this out they should be playing the stock market.

$5000 can buy a lot of hardware depending on the goods and a deal.

I just saw 6 5830, 2 5850 and 4 5870 sell for ~$1000. ( http://hardforum.com/showthread.php?t=1695049 ) That's 5.8gh

Figure a couple good deals like that plus some other hardware costs and you have 15-20 gh for your 5 grand.

If you have cheap or free power you are golden and break even in 3-4 months.

I have 10g/h and it cost me a bit less than $2000 buying up gpu's cheap. I don't have to pay for power or A/C I can run as many machines as I want in a shared datacenter for free. I paid my hardware off in a month of bitcoin mining a long time ago.

FPGA as it is now are a waste unless you have a ton of coins laying around ( that you mined or bought cheap )to waste on them. In a year or two the next killer thing will come around and with the reward halve most people who go to FPGA will never or just be getting to breakeven points.

A cheap ASIC may kill off gpu mining for the average miner who is doing it for profit. It won't stop the hobbyist or the free power people. FPGA wont make much of a dent.

The problem most likely lies in the overhead of p2pool. The shares in the p2pool blockchain have data added, the current miners and shares and payouts that have to be computed in as transactions and hidden in the bitcoin blockchain as an unknown transaction as well as all the current bitcoin blockchain transactions to be considered a valid share. the 10 second longpolls also mean that many created shares are rejected as late/stale and discarded especially for slower miners.

Those are shares in the p2pool chain that could also be pieces of a valid bitcoin block.  The payout value is a guess of your proportional hash power for a block if it solved at that instant weighted by your number of recent shares.

12.1 on win7 seems ok. Fastest still is to use a 11.X one of the later version with the CPU bug fixed and the 2.1 sdk.
dont use 12.3 and sdk 2.1 or it will have ab great hashrate but never submit any shares.

Make sure you uninstall or dont select the SDK during driver install.

Install the 2.1 sdk after the drivers are installed.

Use cgminer, let it autodetect. If you have ever run cgminer before delete all the .bin files in the directory first.
