I have thought about pumping about 8ghash/s in your pool after CDF gets about 40-50%,

but there is a relatively high risk you will just steal the entire 50BTC reward to yourself after your own miner's proportion (mcmeidi) gets lower & lower (and you probably know that people would just leave after the first block rewards anyways)

The 50 BTC will probably be much more than your pool will earn in operating profits in it's entire lifetime after that.
I don't see anyone sticking around after the first block is found.

This gives the small pool owner a very high incentive to steal the entire block proceeds & disappear.
You also have no reputation to lose, joined the forum 48 hours ago & the site seems like an overnight fly-by operation so it's a win-win for you.

Pool luck is extremely bad in the last 48 hours, check stats page. Average has gone from 15 minutes to 30 minutes, but it's still completely within normal variance.

If you don't like variance then it's better to use PPS mode; You get the same reward every day.

Proportional is always a gamble because luck only evens out in the long term; Not necessarily in the duration of a single difficulty.

It protects the core from damage.

On a 6990, I noticed the cards will throttle down a lot after 99 celsius.
Had to buy some extra fans despite the card being in a well-ventilated datacenter..

Advice: Do not sandwich multiple 69xx cards next to one another without really good cooling

Buy from Cablesaurus, these work 100% fine even in 24/7 use, and I bought a version with a Molex power feeder injected in the ribbon = even less risk of something like that.

BTW, my 4th card wasn't detected either when using the riser from CS, until I plugged in the extra power cable.

That's a pretty pathetic botnet. As you can see from the mhash/s he likely harvested a ton of old CPU's.

That's a sound investment plan

Didn't do anything to be honest. No performance dip but no increase either.

Tried on a 6990 and a 5850.

No, it's a long polling announcement which tells your client someone in the network already found the block you are working on,
so you wont waste stale shares on working that block anymore & go onto the next block.

If your client has no LP support you will get up to 1-2% more stales due to hashing redundant work.

Breakeven bracket must use future expected difficulty as well to be accurate.

Diff. wont stay at 1.3m just as it didn't stay at 877k.
So in fact it will take a much longer time to pay off new cards bought today, if price stagnates at current levels.

Yes. Though they are a single card, they draw power worth 2 cards (in the case of 6990, 450+ watts if overclocked) because they have 2 cores.

If you use extenders to run 5970 or 6990 it's safer to use extra Molex power adapters injected in the cable ribbon.

Harry Potter is bigger than the Bible. Just saying.
And I think the 6th book was longer too.

And it's sold more copies worldwide.

Sell everything, invest in white messenger owls and magic wands.

I've dug into this subject. In the name of forced gender equality, Nordic countries are employing nearly all working age females in state-run jobs that do not necessarily produce anything of value, but full salaries are paid out from taxes  (= people who do real work in private businesses)

These include nominal desk jobs, bureaucrats, various do-nothing organizations, 'social consultants' etc.
(But also some vital jobs such as healthcare and teaching, still state-funded nonetheless)

In that sense, the American system is superior. Sure, there's the "rotten elite" who get paid for nothing. But for the average Joe (or Joanne), nope. They only get paid according to what they can do and produce.

There's no secure desk job answering a phone and filing some papers for a 20-something who finds him/herself unable to find any meaningful work in the private sector.
There's no reward for deciding you don't want to take part in work life & fund your kids life through the state and life a relatively rich life (compared to single parents or small households in other countries of the world).

It's as if, in your countries, the state is just an arbitrary substitute for a husband.

In case anybody wants to actually read the stub article instead of being blasted
with a stupid "register for free" popup that takes you off the page if you refuse, here:

All the important points were already posted in this thread & before if you just bothered to search.

Point in case: Very few infected machines have any harvestable GPU's. The vast majority are compromised Windows 98 and Windows XP SP1 machines that are 5-10 years old and run without any sort of antivirus or firewalls.

However, many of them have modern internet connection speeds such as 1mb/s or even 10mb/s+. This makes them very valuable for denial of service attack & extortion business.

If you have constant strain on old CPU's, even computer illiterate people will start noticing & you will potentially lose parts of your botnet for no reason at all.

Is it worth it for the 0.5mhash/s you would get from an average machine with a Sempron?
No. Simply put, utilizing a botnet for bitcoin mining is a waste of money at this point (machines in botnets are each worth a monetary amount, plus opportunity cost as mentioned above).

It should have been utilized when difficulty was in the 4-5 numbers. Remote installing miners on all your machines at 1m+ difficulty is a stupid business plan considering how much more you could earn just by renting out those machines.

I've run one 5850 for 13 months now @ 90% fan speed. No signs of failure (yet).

Signal degrades after 19cm, not possible.

Have to agree with the sneering posts above.
How will you raise a child for 18 years if you can't even pay for the adoption but have to beg for bitcoins to finance it

Sounds like a Nigerian type 419 scam, but if you are actually adopting then hope all goes well.

My math might be a bit rusty but that's around $199 per card, even then it's not a bargain,
seen the same Sapphire 5850 cards sold at $150 brand new 2 months ago (I have a receipt for 3 bought at $149.99)

Someone with physical access to your PC's (say, they know you run a farm with your wallet connected PC among them, and you are out of town for a week)
can remove the RAM sticks, use a freeze attack (literally freeze the RAM with a spray bottle) & boot it up in a device which will dump the contents onto a USB flash drive.

Then they search for the contents of wallet.dat, reconstruct it & steal your Bitcoins.

It's worth it if they know you have a vast amount of BTC, otherwise it's not a very likely scenario.

If you can find one, get a XFX 6970.

Doesn't differ from any other stock model, but they have double lifetime warranty, which means even if you sell it later, the 2nd hand buyer can register it & get life warranty on it.

You naturally also get lifetime warranty instead of 2 years, 5 years etc.
Improves the resale value by quite a bit.

Or if you're willing to overclock significantly, get a 6990 at almost the same price as two 6970's.
It contains two full 1536sp cores of the 6970's downclocked, but you can get both cores to 400mhash/s or better with OC'ing.
