721  Economy / Marketplace / Re: Earn 131BTC or 1BTC for getting shops/organisations to accept Bitcoin! on: June 10, 2011, 05:12:56 PM
Perhaps for a different thread, but what I'd really like to see is a list of the TYPES of businesses we'd like to see accepting BTC.

For me, Im an IT guy by trade, and I'd happily accept BTC for my services, but I don't see the BTC crowd as being in need of a computer nerd Smiley

I'd love to be able to shop someplace like Amazon.

And yes, I know we'd all love to see EVERYTHING and EVERYBODY accept it, but maybe if we make a punch list of types of businesses, say Amazon to start with, we get 10,000 people to all contact that ONE PLACE to accept BTC.

yeah i just switched over to phoenix... i am getting 344 with aggression = 7.  I'm getting 91c/71c.  Its in an air conditioned basement.  The cards are pretty much stacked right on top of one another... using the catalyst control center, 900mhz is the lowest i can go on the memory clock, and gpu clock is currently 850.

Once I just bumped down the memory to 900, im noticing it still runs at about 339 MH/s, but periodically dips down into the 250's.  Any tips based on all of that info?


you might want to try to get that first card cooler.

Definitely want to, but I dont have any kind of overclocking tools to drop the memory clock below 900.  What do you guys recommend?

What are you guys using for clocking and voltage settings?  All I have at the moment is the catalyst drivers.

Want to get those temps down a bit and bump up the speed as well.

using poclbm 1.48 and SDK 2.4 (couldnt get 2.1 working, so I just went for the latest... 5-10% doesn't make a huge difference to me just yet).

What to do?  I'm considering phoenix as I see that a lot on the hardware guide... I will say these cards are huge as shit and 1 more wire in the case and they wouldnt have fit, literally.

Play with the GPU settings, or switch to phoenix first?  BIG difference from 29MH/s with 0.2 BTC/day on a good day lol

Why not create a tool that generates scripts for new users to use BitCoin, or some useful function, rather than DDoS scripts?  How does attacking a site lots of people enjoy accomplish anything positive?
727  Bitcoin / Bitcoin Discussion / Re: Semi-rational exuberance anyone? on: June 08, 2011, 12:15:03 AM
I just really don't see how over 7 days a 25% difficulty increase results in a 300% price increase... I have a gut feeling if I buy today, its gonna drop, and if I don't, tomorrow its up another 20% lol
728  Bitcoin / Mining / Re: Would this quad GPU mining setup work? on: June 07, 2011, 08:38:13 PM
A) You cannot put an AMD CPU with an Intel socket. Moreover, that mobo is socket 1155, so the cheapest CPU you could get with that would be the i3-1200. $99 from Microcenter, or $125 from newegg.
B) That motherboard only has 2 PCI 2.0x16 slots, so you could only have 4 GPUs in there unless you buy some adaptors
C) A 750W power supply is nowhere near enough for 4 GPUs. Maybe 2.

I was assuming that his properly stocked garage included a dremel and a soldering iron... add in a pizza box and some duct tape, and you can make anything fit!
729  Bitcoin / Mining / Re: Would this quad GPU mining setup work? on: June 07, 2011, 01:46:20 PM
I think AMD CPUs are smaller... you should be able to fit 2 AMD CPUs into the one Intel slot.  Since it's in the garage, im sure you have some duct tape lying around, just make sure you use plenty of Artic Silver after you tape them together.  You may need to shpritz a little starter fluid in the carburator on the power supply to get it fired up.  Make sure you do a deep cycle charge on the CMOS battery first, so you can properly overclock.  If you set a mason jar full of Prestone on top of the video card section, that will give you your liquid cooling.

If any of that fails, you could always sacrifice 5 minutes of your time reading about what you're actually going to do first, but if you have a properly stocked garage, the above should work great.

The solution:

Enable power management to +20 in CCC....
I'm running unlocked @ 900 core: 380-400 Mhash/s

Donate if this fixed your problem:

Grtz

Dude, I'm the one who posted the solution in the post directly above your post >_> How are you going to accept donations for posting my same answer right under my post?

LOL cuz he was smart enough to take credit and demand payment?  Seriously though, dick move.  How about "Send me an email saying thanks if you appreciated it".

I had forgotten the joy of a last 30 second ebay auction snipe is Smiley  Just picked up two ATI 5870s for $525.  Not much cheaper than new, but every place seems to have a hard time keeping them in stock.

The question then becomes for me, as a "new guy", do I spend the money buying coins, or buying the hardware... I have a decent PC rig already, minus the video card... was going to do dual 5870's or a single 5970.
I'd say go with the cheaper cards 5850 or 5870 and spend the rest buying bitcoins. But you'll probably be even better off spending all on coins. Expect difficulty to go way up due to the higher price. I think most of the miners who only started the last few months regret not having bought bitcoins with the money instead...

You have to do the math yourself for your situation - if you do, consider difficulty increases of at least 30% every ~11 days and don't count on being able to sell your used mining gear in case Bitcoin crashes completely - you'd be one of very many trying to do so.

Having said that, welcome to the community and I wish you the best of luck!


Awesome, thanks for the input.  Although looking at the next expected difficulty, I think BTC is a bit overvalued at the moment... looks like there's sort of a craze yesterday and today.  I think it will settle in around $15 or so in the next couple of days, which is in line with the last 55% difficulty and the upcoming ~25% difficulty.

I was thinking about the difficulty as far as buying cards, and yes, blocks will be harder to find, but I think the price will balance it out... not much difference finding 50 BTC @ $8 and "only" finding $25 @ $16.

I think you have the right idea though... if I get the cards and the coins I'm covered both ways.  I'm an IT guy and leave my computer on 24/7 anyhow, so it shouldn't be a huge difference for the video cards added in.  The video card I have now is pumping out 28 Mh/s lol.  So pretty much anything would be an improvement.

As far as you guys with the post apocalyptic stuff, BTC is going to be useless if nobody has electricity or internet anymore, if you're hiding in your backyard bunkers Smiley  Food, medicine, and ammunition will be the currency, in that order.

Hi Guys... new kid on the block.

I experienced the same thing trying to buy with dwolla - except I tried to buy at 9 and now its 17.

Just looking at the market cap, it has gone up 250% - if you think of it like a traditional stock, it has gone up more than double, without the appropriate "earnings" - I'm thinking it's going to settle back down a bit.  If difficulty increased 55% at $8, and if we assume its going to go up another 50% or so, (these are all guesses), I'm thinking $16-$18/BTC is not unreasonable.

The question then becomes for me, as a "new guy", do I spend the money buying coins, or buying the hardware... I have a decent PC rig already, minus the video card... was going to do dual 5870's or a single 5970.  I see everybody going crazy for the 6990s, but honestly, the pricing on a 5970 is 400% of a 5870, but its only 200% of the speed.

The advantage obviously being if you have 1 PC, and the "coin" to spend on video cards, you can put two 6990s or 5970s in, which will then be double the speed (or more) of two 5870s.

Unfortunately I took a night to "sleep on it" before ordering video cards, and now they're all out of stock.

Do you guys have a spot youre willing to share that accepts good old fashioned credit cards to purchase 5870 or 5970?  Paypal is the Great Satan, and we refuse to do business with each other, and I don't have any BTCs yet.
