Free market capitalism leads to less concentration of wealth.
Do you have any examples that free market will not naturally lead to monopole? Who is competing against google/facebook/coca cola...? In an information society, it is very common for people to select a few of service provider which ranked in top 3 and ignore the rest And I think the cooperation between biggest market players are much easier than individual person |

Building the Pyramid maybe is the way to create full employment, and the return of this huge project (through tourism) will spread over several thousand years. Those slaves who were building the pyramid everyday, they also got a work, food and shelter etc...
The "Sponsor" concept from "hunger game" talks some truth: In a world that most of the wealth are in a few people's hand, most of the people will try their best to impress these Sponsors, that's where free market leads to
Slavery and war are the solutions you propose for full employment? What an inspiring worldview you have! Well, instead of slavery, you get a loan for your house; instead of war, you get free market to slaughter each other using cash, but does that change the essential?  |

Instead of use law-based rules to guide the society, the interest-based actions are more centralized (Ever heard about the democracy for interest rate?) Governments typically use monetary tool to adjust the economy of the country, although they will create inflation/deflation, but they do have certain maneuverability
When they start to use EURO, many governments lost the ability to adjust the economy according to their specific culture. Same happens with BTC, if a government adopt BTC, they will have no way to affect the economy using monetary policies, and that's the reason gold was abandoned as a currency

Yesterday tried 0.95V 710M/150M setting on 5970 and after some hours one of the GPU dead, seems 700Mhz could be run stable, and at 1.0V 750Mhz is stable
|

5970 voltage steps tested at 650Mhz:
0.000-0.950 xxxW
0.955-1.000 xxx+8W
1.005-1.035 xxx+16W
1.040-1.050 xxx+19W
I think xxx is around 200w, but no precise figure since this is a test from mixed gpu on board

The main obstacle to buying things you want in bitcoins (if someone is selling) is transferring your wealth into btc. Once people are "sitting on" enough bitcoins they will start using them to buy stuff more often.
Good point! And how much is Enough? IMO, there are 2 different measure: 1. I have constant BTC inflow which covers more than my monthly spending (500 BTC per month at today's price ) 2. I have enough BTC that will ensure my living cost of about 3 years (15,000 BTC in today's price) If none of these conditions met, I tend to keep accumulating BTC Isn't this true for most of the people? And due to the limited supply of total coins, these conditions will never be met by most of the people, so most of the people will keep accumulating BTC  |

A big turning point is coming when the block reward is cut by half
If the price of BTC can not double after that, most of the miners will be forced out, and the difficulty will drop a lot, and less people will be interested in BTC
If the price doubled after that, it will show strength of the BTC, then maybe more and more people will notice it
As I understand, the limited supply (not supply speed) is the biggest obstacle for BTC to become a transaction medium, but if the price can be kept high, then it will become a digital collection item

For my 5xxx cards, I found out that 2.2.6 works best. Although 2.3.3 also works fine, the cursor jumps everywhere on the screen randomly
I did see performance drop when I switch to diablo kernel, don't know why

Did anyone tested 5970 voltage stages and what is the maximum stable clock for each stage?
This one is a big heat and noise generator, I guess reduce the voltage can help a lot ...
|
|

I made some measurement again using my best 5870 card, here is the result:
0.000-0.950 stage 1, highest stable 730Mhz 320Mh/s consume 95W/card -------------- 3.37 Mhs/W
0.955-1.060 stage 2, highest stable 880Mhz 395Mh/s consume 135W/card --------------- 2.93 Mhs/W
1.065-1.165 stage 3, highest stable 900Mhz (BIOS limit) 405Mh/s consume 171W/card ---------------2.37Mhs/W
So the highest voltage setting is definitely to be avoided, but weather or not to use the lowest voltage setting is up to each person's preference. As long as the heat and noise is not a problem, I'm satisfied with stage 2 voltage settings, anyway I do not want my hash rate drop too much, time is also a cost that should be put into consideration
BTW, I saw some screen artifacts when I run lowest voltage settings, stability could be an issue

VRM are only capable of certain discrete voltage values.
So if 0.959v isn't a valid voltage the card will actually be running at voltage > 0.959V whatever the next higher step is. Which according to johnyj (not verified by me) is 1.06V
So 0.959V, 0.96V 1.0V, 1.0123456789V it doesn't matter the card is running at the next higher valid step which may be 1.06V.
The only way to verify for sure is to pick a static clock (lower is better) and connect rig to watt meter (like kill-a-watt). Change voltage and look for a change in wattage. No change in wattage = no actual change in voltage. Since wattage is going to have some variance anyways it may require measuring power instead (kWh) and time to get average wattage.
So something like
Set clocks to a static 700 Mhz.
Set voltage to stock.
Measure power for ~10 minutes.
Divide power by exact time to get avg wattage.
Lower voltage and try again.
You will notice something like this
Voltage: 1.05V, 1.04V, 1.03V, 1.02V 1.01V = same wattage. Then at some point the wattage will drop. THAT IS THE DISCRETE STEP.
That's exactly what I did, I measured the change with only one 5870 installed, the result is directly visible on the power meter after each voltage change, I do not remember the exact voltage step location, but my card can run at 1.06v as high as 880Mhz, so I'm quite satisfied at this setting for now |

Bastiat is the greatest. I have a man-crush on him. The concept of the unseen is one of the most important economic concepts for people to grasp. Consider the government-built sports stadium. Hundreds of millions of dollars in cost. When it's built, the people see it and marvel at the wondrous building, and thank the government for creating something so great. They do this because they SEE it. What is unseen, however, is all the goods and services that did not come into existence, because the resources which would've been used to purchase those things was taxed away to build the stadium. But, because it's unseen and distributed over many people and over much time, the population doesn't realize the cost, and instead they stand in naive admiration of the sports stadium, and lavish praise upon the government which has likely made them all poorer. It is a phenomenon present in almost every government program, and it deceives the public in perpetuity. If only people would read Bastiat in school  True, most of the people only care about what is happening now, and what is happening on themselves, that's the reason that long term project which charge a little on each person usually can generate huge return. Insurance for example |

BTC price is the most difficult thing to predict...
If someone can create a very demanded product/service which is only payable in BTC, it will push the BTC price to cloud
Some possible candidates of these services:
Medical insurance
Jobless insurance
Pension fund
If you tell your friends that BTC is the first P2P currency in the world, he might not care about it at all. But if you tell your friend that he can buy an extra medical/jobless insurance using BTC, then he might be showing some interest

On 5870, there are only 3 effective voltage, distributed in range:
0.95v
0.96v-1.06v
1.07v-1.17v
0.96v and 1.06v actually gave same readout on power meter, so you may run 825Mhz on 0.96v, but that will not improve efficiency

angry chimp indeed...thx for the tip D&T, just ordered from frozencpu:
Phobya Thermal Pad XT 120mm x 20mm x 0.5mm - 7W/mk (V-Regs, RAM, Ramplex, Koolance, MIPs, Innovatek) (19099)
Phobya Thermal Pad XT 120mm x 20mm x 1.0mm - 7W/mk (V-Regs, RAM, Ramplex, Koolance, MIPs, Innovatek) (19100)
I figure I'll use both thicknesses at some point as I split my remaining cards open and re-grease prior to the summer months.
Looks like I've got some time to polish up the GPUs waiting for the USPS - thx rjk
I also purchased these pads. For 5970, do not use 1.0mm pads, they will raise the card too much so that the GPU could not have tight contact with the heat sink. 0.5mm pads worked for my RAMs, and I use another type of very soft 0.5mm pads for VRMs |

I have 2 under-volted 5870's.
One at 840/155 and 1v = 384 mh/s
The other at 755/155 and .95v = 347 mh/s
If I try to set the first card to .95v I have to set the engine clock too low to around 400, otherwise it crashes.
The 2nd card is happy as can be at .95v
That's a 5% drop in power usage and 10% drop in hash rate, not very attractive IMO But of course if you have plenty of hash power and want to reduce the noise/heat, it will help |

My main/standalone machine. 3x5830 1x5850 gets about 1.3ghs not the prettiest, but its ultra portable lol get another 200mhs from the 5770 in my everyday computer when i am not using it.  Nice, I'm also taking this approach and want to make a tower sized outdoor shelf by pointing those exhausts upwards and pack the whole shelf with plastic foil |
