Simple way is to look at the power-adaptor... It provides the power, and thus, indicates the power-rating. (Assume it runs at 90% consumption, when mining. 100% if you kill the charger.)

EG, if the output says 14v @ 20A then it is 14vx20A=280W... Then add 15% to that wattage, as most wall-supplies are 15% inefficient. So, at the wall you will see about 260-300W consumed, to produce 200-280W of output power. (Remember, you battery is charging also, which consumes MORE when it is in a charge-state, and less when resting.)

You can provide more "usable power" by blacking-out your screen, turning off the brightness/backlight, shutting-down "indexing services", turning off "defrag services", disabling blue-tooth, cameras, sound, switching to lower resolution or the output-port, etc... Leaves you with more available power for hashing... but if you are not making over 300MHs, then you are paying to hash, as that is roughly about equal to the power you are using to hash. That is ONLY if you cash-in those coins, which takes-away more value from fees and your time to cash them in... all $3.00 a month.

There was no mention that he would be "watercooling them", just that there was a request for watercooling. His interest as stated, was, "I was asking the boss if he would be interested in getting some cards for miners".

The "because" is redundant and useless banter... "because I have gotten alot of email requests for watercooling those cards for mining."

But I digress...

I'll take the XTX cards you are having "difficulties with"... They all work fine for me.

He asked if there was an interest... My obvious answer is no... for waterblocks... but not for the cards.

As for selling multiple cards for $300 each... You are wrong. That is the only price I have ever payed for them. That is what they are worth, before marketing hype, without packaged retail junk, in bulk.

After this month, if I still pay $300, it is a bonus to those who get it. Because the cards will only be worth $250 by then, to me. (Though I am sure a few noobs will still happily pay $1,300-$350 for the cards, as they are selling them for on e-bay.)

The only cards over that price, are waterblocked, or come packed with over $100 worth of games, that are useless to me.

xfx7970s are great for mining...

Gotta kill the RAM-CLOCKS, since RAM isn't used (Not that much, or that fast), which will allow more GPU-CYCLES to be bumped-up...

Also, flip any heat-pipe cards upside down, they will not physically function correctly in a standard PCIe setup. Also PULL air through the fins, don't PUSH it through the fins, which blows the hot air back onto the chip below, that you are trying to cool.

Heat-pipes are marketing hype, when they are not designed correctly, like in those systems. The "Wicks" dry-up and the liquid does not wick up through the HOT pipes, into the HOTTER core, when you blow hot air back onto the core. It evaporates before it even gets to the GPU and condensates back on the cooling fins, or just stays evaporated as the whole unit overheats.

But I digress...

P.S. ALso, exhaust the hot air, don't let it circulate in the box/room... That is equally redundant. Even if it is 110F outside, it is still constantly 110F, unlike a room, that is trying to be AC-Cooled, from 150F from all the trapped heat. It is cheaper to cool the outside air, and exhaust the 90-110F heat-pipe/water-cooled air out the window/attic-vent. Plus, you get free Attic-AC since attics are 120-180F in the summer.

Like I said... ugliness and fans, not an issue...

If you are looking to "market", some novelty into these cards... Don't waste your time... Novelty doesn't make money, it just adds to overhead and ensures we DON'T have an interest in the cards that are modded with over-priced novelty junk.

I'll take 4x 7970's for $300ea @ $1200 total... (Provided that they function for mining, at stock speeds. Ugliness not an issue. Dead fans not an issue either... I provide my own air.)

I'll take another 4x in a month, after I cash-in my income-tax check. (Still waiting for that to come through.)

Submerge it in mineral oil, and circulate it directly onto the chip faces that have an epoxy-heat-sink on top, and a through-hole to a sunk-ground on the bottom.

Beyond that, you can still cool them from the top, with epoxy-heat-sink that is either segregated and vacuum-bonded to the surface, or a standard thermal setup with "spring-tension", that will not damage the package with massive torque-pressure. Yet, still allow the heat-expanding aluminum and board to slide as needed.

The spring tensions can be simple push-through "V" tabs, attached to the heat-sinks directly, pushed through slots in the pcb, between the actual chips along the center-line of the board. (Not at the edges of the heat-sink... You want a center-line so the least movement is centralized and pressure around the whole surface uses the other chips as "supporting" feet to rest-on.)

I use water cooling, strapped to the copper-pipe going into my hot-water tank and sprinkers and tapped into my pool-pump/hot-tub...

Free hot water, lower AC bills, lower electric bills (higher heat = higher resistance = more power consumed)...

Not to mention the hot air is all pumped into the attic, where the 150F GPU air is cooler than the 212F+ attic-air.

That is called ghetto geo-thermal cooling... lol... the cool water coming from underground is a constant 65F here. And I drink coffee all day long, and flush, and shower, and filter the pool, so cooling isn't lacking.

With "no sales" on a "new member" account... I seriously hope you have some realistic form of alternate sales-pitch...

From my perspective, (someone who buys/sells a LOT off e-bay), I can honestly say you and your advertisement look as fake and uninformed as can be.

RAM, SSD, CPU, CASE...

Funny that all you mention in the list comes to well over $6000 in hardware, yet, amazingly, you are selling it for a modest half-price... and can't even afford an actual photo of the actual rig being sold.

Great, you know how to google a gaming-rig and mark it down after stealing the info from the pages.

A "RIG" would consist of a low-power CPU/MOBO combo, 4GB of cheap ram, a USB boot-disk, a 600W PSU... Possibly linux, not windows.

Nice try... But you are not dealing with people here with money to waste on crap they don't need.

BTW 2GH/s... Show me it running at that speed. And show it to me on a kill-o-watt meter, then subtract the cost of electricity, and that 2GH/s (if it even gets that high), is effectively a 400MH/s machine, after electric expenses.

And you are not running this machine why? At a bitcoin estimated income of $391 a month... You would have made your money back in a year. Oh yea, you just purchased it to sell... That is believable...

That is the whole point of advancement... To advance... and Grow...

Without advancement, you fail to provide what is commonly called, "supply".

Yes, it will alter the market.
 - Faster transactions
 - More stability in value
 - Harder to hack, and disrupt, once again
 - Reduced overhead losses from "electric" expenses, which is the greatest overhead at the moment

Will that kill GPU processing?
 - No, new cards come out all the time
 - They are still profitable as-is
 - They can still make money from "transaction-fees"
 - They can still mine new and emergent "parallel" systems to balance the existing advanced "bitcoin" market
 - They can be re-sold for, um, actually playing games, giving money to those for the "advanced" rigs of tomorrow

It is not a total loss... they have had over a YEAR to prepare for the inevitable, and make provisions for advancement.

It is not like we are just going to wake-up tomorrow, and poof, a million 1000GH/s machines are going to be online. They are slowly rolling out, which continues to add to the stability and lower the "shock", while allowing the market to self-regulate and expand.

You also imply that $120 USD bitcoins are some-how actually justified. That value only exists because of GPU processing. Just as $1000USD per BTC will be the new level of "justified value", once the volume of transactions picks-up.

The "legal" issue with CC's, is that they require "proof", of some kind, that the money received can be connected to a sender who "paid taxes", and a sender who, "has not acquired funds from another CC account", and, "can legally be held responsible for the extraction of funds".

Because they use "Federal currency", and operate within, "federal regulated grounds", they must obey all "Federal laws". (Which includes laws related to handling federal denominated currency and insurance protections offered by "FDIC".)

However... A non-insured FDIC banker, such as paypal, or e-gold, or us... can do "almost", whatever the hell we want. (As long as we are honestly recording income and paying taces on the transactions. The income can come from anyone, just as a dollar can.)

Seriously, put up a sign or open a shop that says... "Recycle your bitcoins, and refund your bitcoins."

When you "Refund USD for acquired bitcoins", that is the same as cashing-out.
When you "Allow them to recycle bitcoins, accepting USD donations for finding them to recycle", that is the similar to selling them. (But not an actual sale.)

Getting others involved locally, expands the network, the trust, and encourages more uses to be found. Using existing "questionable" services, only ensures that this system stays confusing, exclusive to those in the know, limited to those with the availability, and focuses all the losses into your future transactions.

Nothing spreads interest more than talking about it, out loud, to friends. Eventually, this whole system will become more "user friendly". Funny, that all futile attempts to hack it, have led to greater expenses to the hackers, and better returns for those using it honestly. The people won, script-kiddies lost.

The only way to build trust, is to "build it", not "beg for it"...

To "build" trust...
 - Provide as much (real) information about yourself, your location, your credentials...
 - Ask the same, within reason, from those you intend to deal with. (eg, showing that you don't intend to deal with, "just any untrusted sources".)
 - Ask those who, have earned your trust, to kindly post some kind/honest words about the experience with you. (That is not a 'testimonial' hosted on your site. That makes you look like an untrustworthy person. Eg, forums, blogs, social sites by dropping your name, not by spamming ads.)
 - Be patient... If you seem pushy, that reflects as being "untrustworthy"... (eg, gimme, gimme, gimme, why, why, why... Instead simply ask... What "other" information would you like me to offer you, before you "feel comfrotable", with this transaction. As opposed to saying, what can I do to make "you trust me"... Makes you seem untrustworthy again.)

Go to javaconsole in your control-panel, and "delete" the temp files.

You can also delete the downloaded files, which may be in temp-net folder, or some other location for java. (Gotta research that for your system.)

Just delete them, go to the bitminter website and click the LAUNCH again, and it will redownload the latest version again.

If you are saying, "Java just did an update"... Then you may have "just installed a virus/trojan"... because Java DIDN'T "just do an update". (It has been nearly half a month since the latest java update, which was a minor security update, not a major code-breaking update.)

nope, you did it wrong... try it again, I can't see it!

There are machines running online now. There are many videos of them running, connecting, and in "reviewers" hands (for the new ones)... The older ones, are in many peoples hands already.

Google it, youtube it... This is old news.

Only the "new versions", are just-now being "given out", as they pass production testing. This is not bigfoot here. These do exist. Unlike any other "still in creation" device being offered.

Releases are slow, at the moment, as expected, as stated. It has been confirmed as "not a scam", if that is your fear. This isn't an over-night company.

Best expected CPU speeds I have seen is about 2.8MH/s... My OLD GPU GTX9800 does 23.4MH/s alone... and won't kill my CPU in the process. I don't care if my GPU dies, I have three others to replace it!

(@ $125USD per BTC)
2.8MH/s = about $0.017 a day
23.4MH/s = about $0.16 a day
230MH/s = $1.64 a day
2300MH/s or 2.3GH/s = $16.45 a day
25GH/s = $168.75 a day
250GH/s = $1,687.55 a day


Until the next difficulty level, then divide that result by 8...
Then the next difficulty... Divide that by 16...
Then the next difficulty... Divide that by 32...

EG...
25MH/s = $0.17 a day = $0.005 a day, after the difficulty has increased 3x
250MH/s = $1.68 a day = $0.05 a day, after the difficulty has increased 3x
2.5GH/s = $16.87 a day = $0.53 a day, after the difficulty has increased 3x
25GH/s = $168.75 a day = $5.27 a day, after the difficulty has increased 3x
250GH/s = $1,687.55 a day = $52.73 a day, after the difficulty has increased 3x

I am not good at good-bye's... 

How about I just give everyone a silent hug, and walk away... 

Hmm, think I can post four-hours of good-bye posts to practice saying good-bye! 

But, but, but... I don't wanna go! 

Ok, last smile before I depart... No wait, I still need 3 more hours of postings! WTH! 

So what will sending YOU bitcoins actually proove?

That they exist? That they work? That you are a cheap begger? That, somehow, in some fantasmal way, that is "trust"?

Obviously a SPAM post for money. See you on your next spam account... bye-bye!

One connects, the rest get rejected

lol, I am confuse!...

BFL uses too much power? What? It uses 1/100th the power of any equivelant non-ASIC rig! (Even at its new reported power-use.)

But as for the laser-disk player... I agree... This is, for most of us, a "toy" a "novelty", a "gadget"... But for the remainder, it is a legitimate and serious "investment".

All investments have risks. Nothing is "risk free"... Nothing! (Thus, it is redundant to even mention.)

Still, the fact of the matter is... ASIC is not the pipe-dream many are "tricked" into believing it will be. It is a very real "dream crusher" for those who will own one, and those who don't own one.. but not for the market and not for the people using bitcoins. For them, it is a "required and needed" advancement. Faster transactions, more stability, more availability, and less coin-overhead. (As opposed to now, where the value is mostly "lost shelf-life" inflation from power-hungry kids running overpriced GPU's and CPU's to handle the load.)

The value will continue to rise and fall, even after GPU's stop being used. THe next market level is roughly 1000 USD per BTC, naturally, until the next-gen hardware and volume of transactions increase. The missing element here is still "trust", which is the ONLY limiting factor of this market.

If you want to make more money... from bitcoins...

Cteate services that accept bitcoins... Buy/Sell bitcoins directly... Create a LOCAL exchange... Convince others to USE bitcoins...

Create ANY form of a "Trusted" exchange, and you will thrive more than any mining-operation. (People want TRUST, if you offer it, you have a never-ending supply. Until you bteak that trust, or dishonor it.)

That is what keeps the value of bitcoin rising and stable. Theft and deception only devalues it. Obvioulsy, theft and deception is decreasing, but still exists, thus, all the horrible fluctuations. But it does not dominate, because the market has never crashed. It was built with GREAT anti-trust protection, so adding TRUST is easy.
