Re: How to update drivers/get OpenCL on a Sony Vaio?

on 21/04/2013, 17:32:13 UTC
the only versions in those links were windows 7 or vista, im running XP currently
Not sure if this is what you want to hear, but I have windows 7 32 bit and tried the same thing with my vaio.

None of the homebrew drivers seemed to install OpenCL for me. Maybe better luck with 64bit homebrew drivers as they're newer?

Re: Explain wallets to me

The very fact you've used your private key to send money to the small wallet means that private key is no longer safe?
This is the part that I don't really understand yet either

Free iphone web app w/ exchange rates
by

I'm developing a web app for the iphone/ipad. It is for quick reference of BTC exchange rates from multiple sources.

It currently provides rates for major currencies on the bitcoinotc & blockchain exchanges. And BTC/USD rates at MtGox & btc-e.

Visit http://clickco.in from an idevice to check it out.

Thoughts for improvement are welcome.

So, is it not ok to have a computer on 24 hrs a day?
That's not really what I was trying to say. I was trying to look at the scenario where a typical person starts bitcoin mining. I know your average pc user doesn't have their PC turned on 24 hours per day but that may well become the case if they start mining.

Not sure if I'm right on this, the asicminer being bid on does 12gh at 86W and the current hash rate is 70265gh so that adds up to just a little under 500kw to run the worlds most powerful security network. That techs development was publicly funded with Bitcoin.

EDIT: 10gh, 12gh is an overclocking estimate so 600kw.
Food for thought. We're not all using asicminer just yet though. And do you think the global hash rate might increase once everyone owns an one ? Wink

Re: Mining noob but quick learner, 7970 Asus preferential set up

Just got it yesterday, extremely stable for overclocking, pulls up about 600 mhas/s for now.
According to this info Robi has shared, should be able to get about 700 with a bit of work.

Hi, I got one of these on order. What settings are you using to get 600 and can you keep us updated as to stability at that overclock.

....Where I live solar is common and grid power is not especially cheap, so it become more sensible to mine during the daylight hours only and use just the solar power. Though it slows things down considerably, if your power costs are substantial it can make sense.

You would need more qualitative data to know for sure. For instance some countries have a high or even 100% green energy. Some individuals use solar power. Some might use off-peak which would otherwise go to waste. etc.

Interesting, so depending on the power source, a 12/24 rig could be much more than twice as environmentally friendly (and cost effective) than a 24/24.

Fair point, to a newbie it could seem like such a waste of energy to get no physical return.

So as efficiency increases, more devices get used, will power going into mining (globally) decrease or increase ?

Just wondering what peoples thoughts are on bitcoin mining.

In a simplified case, say you mine with your pc 24 hours per day you are more than doubling your power usage (increasing carbon footprint) compared to if you used it for 12 hours or for an 8 hour working day.

Re: Mining on the road (reduce energy cost of mining)
by
decentral
on 17/04/2013, 11:43:35 UTC
Say for example you are on the road for 8hours per day, you're driving anyway, say inner-city taxi driver. Am I correct in thinking that alternators are rated at a (marginally) higher power output than the power drawn by electronics + power required to charge the battery?

Mining at work / free electricity aside Wink

Mining on the road (reduce energy cost of mining)
by
decentral
on 17/04/2013, 11:19:17 UTC
I've been thinking about how the cost of mining could be reduced.

You've got the obvious ways like using renewable energy as a power source but has anyone thought of using 12V (of 24V for trucks) whilst on the road?

Would mining over a mobile internet connection be possible?

Hi bitcointalk community. new to bitcoin, maybe I should have paid more attention to it when I read about it a couple of years back Smiley
