Which is exactly why it encourages 24/7 mining.

Your earnings are consistent and predictable, on a proportional pool you are discouraged to mine 24/7 because pool hoppers are eating away at 5-10% or more of your earnings.
You are statistically encouraged to switch away at certain times and hop in early during the start of rounds.

This incentive to 'cheat' (or rather maximize your earnings) doesn't exist in PPLNS or PPS schemes

From what I read, in Q2

Also, AMD and Nvidia account for nearly all of TSMC's business.

I'm just posting the news as they come because the delays are relevant for mining

http://uptonews.com/07/tsmc-admits-28nm-ramp-up-is-taking-longer-than-expected.html

Their specs don't list precise dB numbers, but it promises 'whisper quiet' on all speeds. A retailer near you might have a sample piece to try out.

To my ear it sounded maybe ~20dB on high, not whisper quiet but definitely something that wouldn't disturb your sleep. Magnitudes quieter than the 6990 fan on 50%.

Bad news, interview of TSMC CEO confirmed 28nm chips will be delayed because AMD/Nvidia have canceled their major orders for this year.
28nm chips will only account for some 1% of their revenues by end of Q4 this year

Doesn't sound too promising for a 2011 launch

PPLNS is probably the best, also encourages 24/7 mining (some would prob. still continue mining after 1st round rewards),
zero financial risk to you, no pool hoppers or other cheaters, no risks typical to small startup proportional pools

(such as zero payout for days, weeks or longer due to long 95+ percentile round)

Nice perks.
Would definitely throw all my hashing power here temporarily if it wasn't for the proportional payment method.

I run cards in a dedicated place with ventilation so just default fans..

If you run these at home you will *need* extra fans blowing air on the cards if you want to actually live in the house.
(Well.. Even if you put them in a basement, many cards next to one another will still run very hot)

The fan noise of these cards at 100% is absolutely unbearable.
Actually measured ~85dB with a professional Extech decibel tester a few meters away, which is not that far away from a small jet engine.

Anyway, if you want to cool a ton of rigs at once, try these. They are very power efficient for the amount of CFM provided.

Home Depot, Costco and some other big retailers routinely carry these in their inventory.

Pre-4xxx series cards don't have OpenCL support.

Humidity is fine, condensation wont be happening
Rainwater on the other hand will obv. kill your rigs if you do free ventilation by just removing hot air from your compound

Use some sort of curtain so that rain drops aren't coming into contact with the rigs in any way.
That way you don't have to shut the windows and have massive heat buildup during storms

Sure, but you don't represent the average female online consumer, who will likely guess Nvidia is some type of eyeliner.
Of all the products I've sold on forums and sites like alibaba/ebay, women would only order or locally pick up things like open box Prada shoes at a discount. I've sold computer stuff to a female customer maybe once or twice, and those were basic ethernet cables to an old lady.
 
It would be a big waste of cash to market GPUs or anything related to mining to that demographic

If only online retailers like Zalando that cater to mid-high range female clothing and shoes would accept BTC as a payment method, the popularity among bitcoin would skyrocket, largely due to word of mouth and positive image due to assurement from a big seller.

You never know about fashion designers either, their personalities are one in a million, some like Ralph Lauren might be quirky enough to consider payments in bitcoin after reading the concept.

Mine with it, very profitable considering you picked it up for $70 & it yields 400mhash/s at best.

In fact at the current & upcoming difficulty you'll pay it off fully within about 2-3 weeks. Not just that, but it has a real resale value of at least $120-$150.

So congrats, you stumbled onto free money (well, minus the power costs.. No free lunch)

Stereotypes can be profited from due to some reasons you listed (grain of truth, etc)

If women want to buy shoes, purses, jewelry, makeup etc... Then let them. I'm not arguing women aren't different from men; They are like day and night when it comes to purchase patterns.
Men don't give a shit about purses and makeup, and women don't give a shit about electrical stuff or hardware.

Sell female-oriented products with easily obtainable bitcoins and you're in for a massive market.

From a business persp., nobody should care  'why' they opt for those products as long as they have money to pay for it.
I for one don't care whether the revenue comes from someone with a dick or someone without. I don't care about the evolutionary psychology behind it.

The only relevant thing is they have enough money to pay for something marketable with bitcoins, which makes women an untapped market worth a lot of money.
If bitcoins were easier to obtain than Paypal funds or credit card payments, ordinary women would use BTC every day.

Everything about the site screams scam.

Only on watercooling or various types of extreme cooling on the VRM's, any realistic attempts at 24/7 mining will be limited to about 1.20-25 on air.

I don't think the mod is financially worth it, unless you have some cards to 'spare' or got one for free

The hardmod (or rather enhancement) does enable much higher stable max. voltage,
the problem is how do you transfer the heat when VRM temps shoot up to 150c

(and it still wouldn't help OP as he runs Linux on an earlier revision, so in essence his problem is unsolvable unless someone codes a tool like Trixx for Linux that accesses voltage regulators on the 5850 xtreme, as conventional volting tools don't work)

bsod error suggests GPU driver being the culprit, did you run driversweeper before installing 11.7

Lower the GPU core clock frequency, set voltage to default

Obv. pure PPS is ideal for the miner since he risks nothing and gets zero variance day in day out..
But it's not viable for you the operator unless you have massive reserves of BTC in store for a stormy period. Even then you'd need some sort of fee to fence off your risk, deepbit for example has 10% and rfcpool.com has 7%

PPLNS doesn't require any buffer on your part. It also can't be exploited statistically by hopping in after many high percentile rounds to profit from early, valuable shares of likely upcoming short rounds.

Short reading

Well noticed. Without looking at in-depth charts, I don't think I've ever seen BTC/€ significantly under 10 euros. In the low 9's but that's it.

Miners probably are reluctant to sell below that price point, there is no rational reason why it didn't plunge down to 7€ back when prices plummeted to $10.25

Wow. Finally some unique and useful features in a startup pool. That remote control scheme is definitely a world-first.

The only thing that stands out negatively is prop. payments.
As you might know it's one of the worst models for a 24/7 non-hopping miner, any plans of PPS variant schemes or PPLNS?

It's worth the near-zero risk of bricking the card, you gain in the best case 40-50mhash/s more. Worst case the extra cores are defective, you lose nothing.

Really, if you have a 2gb model they even have a dual bios switch, you can't screw up in any way (even if the flash went bad, just switch back to bios1 and try again)

Anyone can do it and it's safe.
