One of the ethernet ports on my 4-gpu rigs died a few months back;
As an emergency solution over the weekend (no spare ethernet cables) I plugged in a Nokia N8 phone via USB and used it as a 3G modem.

Worked just fine for 3 days of mining. The bandwidth is about 4kb/s.

As 'myself' said, not worth the ridiculous extra power consumption your added voltage will incur

Also, running at 420mhash/s 24/7 on a 5850 means you have an overclock of about 30-40% from the base 725mhz & have raised the voltage sky high,
have fun ruining the VRM within a few months

But people will do anything just to see a higher number, even if that extra 40-50mhash makes you $0.30 daily & costs $0.20 in increased electricity

The worst black market traffic going on there is images of child abuse and various drugs by a core group of a few thousand people participating across all of those message boards and markets

The vast majority is 'normal' people just trying to see if there's really anything repulsive in there & people genuinely concerned with their safety or simply unable to connect to the real internet otherwise (oppressed people in China, law enforcement agents or soldiers in foreign nations)

You will be very hard pressed to find real, functioning assassination markets there. Even if you did, they would likely be TOR hidden services only circulated among a few anonymous people who have various means of contacting each other.

Nobody is going to take offers from random people joining a message board.

Degrading your laptop & running it 24/7

for .25 cents per day

They get to heat their homes for free.

Makes reindeer spotting & returning from ice fishing trips/skiing in -50c weather that much more fun

And they could sell polar bear skins for bitcoins

If there were any polars bears up there

Those exchange rates are just fine, roughly what you would get at a Forex exchange anywhere in the world at the moment (minus the 1% fee, because in reality nobody will exchange at the nominal 0.69€ per $ current ratio because they need their own cut as well)



The only 'wrong' thing I see is the fees,
I'm not going to pay 20€ for anything else than express wire transfers, and even those, very seldom

Since you wanted to get technical with words:

http://dictionary.reference.com/browse/rat

Most modern uses of the word refer to the concept of a person just as Rwandans used the word 'cockroach' during the mass extermination of tutsis and moderate hutu people in 1994.

So you might have wanted to pick a better cop-out word & explain it to the judge.
In your context it can only be intepreted as a human being, how many people have been robbed (def. stolen by the use of coercion and violence) by a rodent?

Then it's just another modded case (which is good), the point being that standard enclosed cases are horrible for bitcoin mining
Nobody can just buy a ready closed case & expect to stick a total of 8 gpus in there, the temperatures will kill any attempts at mining

Open or no casing is really the only way to fit 3-4 dual GPU's like 6990 into a single setup

The cablesaurus A1 chassis was pretty much perfect, all you need is a few fans & it could house 8 GPUs just fine top-mounted



Crappy image quality, had to find a small icon off cache & stretch since they no longer sell it

That's good for you. I also run a 20ghash cluster @ datacenter but have recently sold off some hardware due to unprofitability, down to 15gh

I think it's insanity to add more HW at a point in time during which your investment will likely never be fully recouped (unless gambling on massive future price hikes) but if you or your investors have the money then go for it

People like Vladimir bought their hardware long ago and have made profit for months, I can understand keeping them online,
adding 100ghash/s more capacity at this point seems nuts but you've made your calculations & predictions

No, you're scared shitless the feds will bust down your door so you did what countless people before you have done:

I don't care enough to report some guy in his moms basement looking for some weekend excitement because he's out of money, but someone else probably does.
Hell, the cops don't care or know if you're just "playing a joke" or "actually talking about rats u mad lololo"

All they need is the original post as evidence even if you claim 'prank'

(TL;DR: I'm not going to report anything, just saying cover your ass before making dumb jokes unless you want to be just another statistic)

It's not, acting as an intermediary makes you an accessory by legal definition
Accessory to conspiracy to commit murder and abetting a felony makes your offer a federal crime even before anything has taken place

Just because you don't make the hit doesn't mean you aren't criminally liable

See the Supreme Court ruling on Standefer vs. the United States

Have fun spending $50,000-$70,000 dollars just on the GPUs (and that's with mass discounts)... Not to mention power supplies, motherboards, electricity consumption, fortified fuses, processors, professional cooling, rent and guarding fees for massive racks

Tbh, renting his mining power at just some % over normal PPS rate is a bargain,
I don't see why people are so skeptical or against it

I'm usually very skeptical against all sorts of BTC ventures (and still am about buying 1ghps for £400 per month, to be honest),
but variance stabilization of a pool makes perfect business sense for both parties of the deal.

You'll make much more eventually as the pool owner when it gets going, if you stagnate at 1-5ghash you'll never grow and will likely die from just a few consequent unlucky blocks

Conspiracy to commit murder, conspiracy to commit a felony, conspiracy to commit assassination, conspiracy to commit a federal crime

Just a few federal offenses you have already done if you live in the US

http://codes.lp.findlaw.com/uscode/18/I/51/1116
18 U.S.C. § 1116 : US Code - Section 1116

Sure you can later claim it as a "troll" if you get figured out.
Remember it's something which nets you 25 years to life, or the death penalty in some states

Even if you're not in the US, it's still punishable in nearly all countries of the world
If you really were selling such a service or offering middle-man arbitrage, you wouldn't be doing it on an open unencrypted forum of a web currency.

All in all, a good way to attempt a 100BTC scam or the more likely explanation of boredom and attention seeking, although a very dumb method

I'm not against people trolling for fun, I'm against people who think there are
no real life consequences online just because you use a few proxies, in short I'm against stupidity

That's because the worst binned 6970's become 6950's.
I.e. the last shader units are of very poor quality and are physically burned off from the GPU die with a laser.

Some 6950 GPUs are fully functional 6970's, artificially binned as 6950's to meet market demand.

Whether you get one of these units is just a pure luck of the draw. Just about all of the 2GB versions can be unlocked & AMD even included a BIOS switch for that purpose

GPUs in the 1GB versions are mostly the poorest yields at TSMC that are not fit to be full 1536 shader GPUs but not weak enough to be fully discarded/downgraded into 6870 GPUs with even more shaders cut off
if you do a hard mod by soldering & get lucky with a relatively good chip it might work, but with a much lower success rate than the 2GB ones

For you to see the full 1536 shaders, they need to be there physically, if not you will only see 1408 even after a successful flash

"The long run" meaning months and years, not a few days or weeks..

You can't get 'consistently' more than 100% of your expected earnings over the long run from prop. pools unless you cheat by exploiting defective pools with no scoring methods (pool hopping)

Deepbit is large enough for their sample to be taken seriously, after ½ a year at multi ghash speeds, their luck pretty much averages to +-0% if averaging all past difficulties
https://www.deepbit.net/stats

But those are only processed by large pools out of good will and compassion towards poorer members of the BTC community, which is possible due to the (still relatively) low difficulty of creating new coins. That's not going to last forever.

Some hosts like Eligius already reject big transactions with low or zero fees. That will likely become more & more common in the upcoming months and years, esp. with bigger pools like slush/deepbit who have to pay for the bandwidth of free & near-free transfers of other people.

This.
Everything else is rubbish.

Consider that the 6990's *alone* will generate about 1500 watts of heat output. That's on top of the heat coming off your power supply, processor, HDD, RAM, , motherboard, northbridge/southbridge etc.

Maybe a massive Silverstone Raven I/II case with tons of extra fans & upwards rotated motherboard tray can cool 3 of them (enough not to bluescreen all the time), but even then you'll run into heat issues. Not even the biggest Lian Li fulltower cases can adequately cool 3 6990's

Your options are pretty much running an open case or wind tunnel, or watercooling.

Think of it this way: Could any case out there sufficiently cool 6 separate 6970's overclocked? That's what 3 6990's are. It's mission impossible without improvisation, living in Antarctica, Finland or the North Pole, or removing side panels.

Try Sapphire Trixx. It works on every single card I have across all my rigs, it can apparently control any sort of memory.

I also succeeded in downclocking to 820mhz on the memory with MSI Afterburner 2.2.0 B5, though it displays at 819.

990mhz is an absolutely insane overclock. Don't start with stuff like that, not to mention the fact most 6990's can't take those frequencies (even if they can you'll have to up the voltage leading in too much power consumption compared to the extra hashrate)

I find 920MHz a stable frequency which yields about 410mhash/s per core for a total of 820mhash/s per card.

I got way past 450mhash/s per 6990 core on 3% mod POCLBM with arguments -v -w128 (for a total of 900+mhash/s) by setting a clock frequency of 950-960mhz and upping the voltage.

Temperatures go through the roof though & so does power usage, so it's not worth it by a long shot.
6990 is already the hottest card out there, I don't want to risk failure by running at constant 95c-100c+.
