941  Alternate cryptocurrencies / Altcoin Discussion / Re: Namecoin - one huge step closer to being a big market player on: June 20, 2011, 07:43:51 PM
That's interesting news. How would namecoin go on about making .bit domains accessible to everyone, though?

Currently you need to set a custom DNS which is gibberish to the average Joe and 99.9% of people. People will definitely like the fact they can't be revoked, stolen or hijacked, but if you can't just type it in the browser bar as you would .com, .net, .org etc..
It wont be much of a hit product.

If your room is at 90 degree(i guess fahrenheits) and your gpu is at 80 degree(with same scale) then your temp sensor is broken.
i have a coolmaster 932 full tower and the computer is cooler then the room cause of the fans inside it.(this is the crossfire 6990s)

I don't know how familiar you are with the law of thermodynamics, but it's not possible to cool an object to sub-ambient temperatures using surrounding air, no matter how many 'fans' you have blowing on the card.

No, you're not going to catch a break. We don't give breaks to people scamming bitcoins, so we're not going to give breaks to people scamming newegg.

It's ok to scam companies. They are evil and bad, like corporations.

They are run by androids from Mercury and have infinite money supplies.
The shipments also teleport from warehouses into DHL vans the moment you order stuff.

If they have good faith clauses it just means they just want to be exploited.
Like, when your parents give you their Lexus to "drive to the store" and you go drifting instead and smash into a traffic light.
 
Those suckers got what they had coming for them, 'believing' you. Pfft.
No matter if nobody else in the neighborhood gets to loan cars without supervision anymore due to paranoia.

Consequences is just a buzzword. Screw the world. Haha, "the world". Those guys suck.

Not my fault they bough nvidia cards  Cheesy

Nvidia cards are superior for distributed computing in general. Take F@h protein folding, or space research such as SETI for example;
Nvidia cards fetch 4-10x more performance than a comparable ATI/AMD card.

Also most supercomputers in the world use Nvidia cards or ASICs.

945  Bitcoin / Mining / Re: What are some of the dangers of voltage tweaking GPUs? on: June 20, 2011, 06:13:44 PM
Take a heatgun and point it at the VRM/power intake.

I'll give you a hint: It's about 110 celsius when you operate at stock frequencies which is well past boiling point.

It jumps up to 130-140c even with a 15% overvolt.

Yes it can be sustained for a short time, but it's simply dumb for 24/7 operation.
It makes no sense for bitcoin mining. It might make sense for short term gaming gains.

Core temp of the chip itself tells nothing of stability like pointed above (but it has a much lower thermal threshold than VRM; it will downthrottle at about 100c.

What card are you using that has 110 celcius at stock freqs? And is that when bitcoin mining is going on at 100% load you mean?



No GPU core can go to 110 celsius. It would downthrottle immediately much earlier.

VRM is the voltage regulation module on a GPU silicon. The temperature of the component is about 100-110 celsius even if you run the core (which shows in afterburner) at 60-70c.

The more voltage you add to the card the hotter the VRM gets.
When it gets past 145 celsius (for comparison; much past the boiling point) at 20-30% overvoltage, you are accelerating it's death. They are not specified to handle those temperatures in the long term. For game benchmarking it might be OK to run the VRM at those temperatures for half an hour.

For 24/7 bitcoin mining you are just asking for the card to die within months or even weeks.

Here is an example of a voltage bump from 0.912 to 1.025v in conjunction with a 170mhz overclock & what happens.

Mark Zuckerberg was a "kid" barely in his 20s when he created Facebook. It was also riddled with problems after it started expanding.

He's now 27 and owns one of the most valuable companies in the world employing 1000+ people and is a billionaire. Point?

The current economic crisis was started by bankers in their 50's and 60's taking astronomical risks and speculating on garbage loans in the US housing market. Age doesn't mean anything.

Don't worry, mommy will bail you out. Or newegg. Or the gubernment. Or Jebus. Just don't cut your finger playing in the big bad world.

Mt. Gox aren't some guys in a basement.
They have a massive office in Cerulean Tower which is one of the most expensive areas in Tokyo. They are a registered company that pays taxes in Japan.

You can even visit them or check the place on google maps.
I think you are discounting the fact that their turnover is often nearly a million dollars per day.

Is Sony just a mickey mouse operation because all their data was stolen?
No, it's one of the oldest technology companies in the world.

p.s. People, companies and stock market officials have been sued after real life flash crashes.
There are countless cases where a computer error executed a sell order in a wrong sequence (i.e. 60,000 stocks at $1 instead if 1 stock at $60,000).
949  Bitcoin / Mining / Re: What card to get? on: June 20, 2011, 03:23:02 PM
A single 5970 can work at 800MH/s according to this.

Yes, and a 5850 can work at 425mhash/s if you OC the core from 725 to 1015mhz and up the voltage by about 30%.
Good for mining if you are setting up a one-week operation.

I hope people don't blindly follow the chart but also use their common sense & think what is a safe 24/7 clock frequency.
950  Other / CPU/GPU Bitcoin mining hardware / Re: 5970 or 6990?? on: June 20, 2011, 03:16:54 PM
You have to raise the voltage and OC to 950-990mhz which I'm not going to do, and wouldn't advise anyone else to do so either.
The card is already pushed to it's limits running practically two full 6970's if you switch to the normal OC mode (830 -> 880mhz plus increased memory clock)

I'd never run the cores at nearly 1ghz and over 100 celsius 24/7. Even with watercooling I think it's unsafe and stupid with a $800 card.
951  Other / CPU/GPU Bitcoin mining hardware / Re: Anyone use a splitter like this ? on: June 20, 2011, 03:08:59 PM
It's not designed for x16 graphics cards but rather various x1 expansion cards/sound cards/PCI-e work tools.
For your money's and warranty's sake don't use something like that for mining.

If you put 4 PCI-e GPU's in the slots and fire up your motherboard, the splitter will draw 300 watts just from one socket.
It will fry the motherboard within a second.

However if you decide to, at least use one of those modded cables from cablesaurus with a Molex connector feeding extra power to prevent damage.
952  Other / CPU/GPU Bitcoin mining hardware / Re: Second graphics card not detected??? on: June 20, 2011, 03:05:24 PM
The second card has to be either dummy plugged, or plugged into a live monitor.

Otherwise it wont be detected as being active.
953  Bitcoin / Mining / Re: New Difficulty Calculation on: June 20, 2011, 02:55:16 PM
watching their value go from 17.50 to .01 in minutes

Why do you keep panicking on the forums week after week?

The value didn't "go from 17.50 to 0.01". Someone simply filled all the sell orders open on the market. Google flash crash; It's happened on the stock markets as well.
Those "placeholder bids" aren't supposed to be filled, but if someone actually buys them at that price, the system doesn't discriminate.

Tianhe-1 has 7168 Nvidia S1070 tesla gpu's.

Their hashing power comes to around 1.1thash/s which is about 12.5% of the total bitcoin network capacity, or less depending on the timeframe.

It's ranked #1 on top500.org as well.

I don't notice any difference between Phoenix and POCLBM using a 6990.

In fact Phoenix just makes it run too hot without noticeable speed benefits (using sdk 2.4).
Also core 0 is always about 5% slower than core 1 even though both have the same exact flags.
What speeds do you get?

351mhash/s on core 1, 339-342mhash/s on core 0. Also core 0 temperature is 92c constant, core 1 is 78-81.

Doesn't matter what flags I use or none at all; Core 0 always runs hotter and slower.

Nothing else is being used or run the card.

Yes the currency in my bank is a physical object, and I need to put in physical currency for it to reflect as a digital value. Yes it is tied to the value of gold like all currencies in the world....this is so funny....also, speculators ( if you have the capability to understand the context) are a bunch of noise and trouble.

Interesting. What currency are you using that is "backed by gold"?

Certainly it isn't the US dollar, Euro, Yen, Chinese yuan or Great Britain Pounds, since those are all fiat currencies with no intrisistic value.

I need to know as I've only made instant payments in the past, but took a break, and my accumulated coins have been withdrawn to my BTC address.
959  Other / Obsolete (selling) / Re: Selling Mining Rig with 2x 5850's for BTC on: June 19, 2011, 09:25:03 PM
That's because we own identical rigs...

Now, do you have any legit questions or are you here to troll?

Why did you only change 2x dummy plugs to 1x, and 4x case fans to 6?

You are a tard. He didnt change it to 6, I said I added 4 additional fans but the case comes WITH 2. Making a total of 6.

He has the same system because I helped him and sent the links to what I bought.

So you join the forum 2 days ago on June 17th, give him advice on which rig to buy,
he recieves & builds his rig in 2 days, decides to sell it instantly at the same time you do on June 19th.

And you both post about 15 minutes apart every time & both make a selling thread with identical systems within ½ an hour.

How stupid do you think people are?
