821  Bitcoin / Mining / Re: Is rig building still profitable? on: May 20, 2011, 05:39:34 AM
How are you planning on achieving 1.5 Ghash/sec with an $800 budget?

5870's are $250 apiece at the moment and each only get around 350 Mh/s and are one of the most cost efficient GPUs at the moment. Even 3 of them would not get 1.5 Ghas / sec and that's not including the substantial cost of the rest of the equipment that goes with a computer.

well, in fairness, he did say "0.5 - 1.5".

two 5870s can be had (recently, anyway - if not today) for $225 each - and the rest of the box (CPU, motherboard, RAM, the box, a couple extra fans, and a PSU [all software is free, of course]) can be put together for $225 if you're careful and maybe a bit experienced.

and really, you should be able to get 775 Mh/s out of a couple of 5870s without trying too hard.  i do.

his numbers work.  and mining is still quite profitable.

Looks promising. A pretty decent hash speed to start with. Can't wait to see where the community takes this.

indeed.

let us keep in mind that when the Bitcoin client was first released, the very idea of even 20 Mhash/second was like some far-off holy grail.

80 Mh/s?  that's pretty damn stout for a first whack...

824  Bitcoin / Mining / Re: AMD Catalyst 11.5 Discussion on: May 19, 2011, 03:21:47 PM
installed 11.5 on a dual 5870 miner with Debian testing and SDK 2.1.

running DiabloMiner, the only oddity i noticed was that my Mhash/sec started out comparatively high (820+), and then settled down to a lower figure.

i've tried a lot of other combinations of CC + SDK (always on Debian), and the Mhash/sec has always started low and gone up to a higher, stable number.

kinda weird, but it works fine.

and the new version of DiabloMiner with BFI_INT is absolutely killer.  i need more fans... Grin

826  Bitcoin / Mining / Re: help cant boot w/ 5850 on: May 19, 2011, 01:57:39 AM
Ok, I took the motherboard out of the case. Booting it up on the insulated material it came in. With one graphics card plugged in, and one stick of RAM. Nothing else.

When I boot, instead of 3 long beeps, I now get 1 long beep, and 2 short beeps.

MSI website says this means "A video error has occurred and the BIOS cannot intialize the video screen to display any additional information "

What are my options now?

you probably need a monitor plugged in.

what are you using?  a monitor with a VGA connector - plugged into a gender-bender on the first DVI plug (the one in line with the PCIe slot the card is plugged into)?

828  Bitcoin / Mining / Re: help cant boot w/ 5850 on: May 18, 2011, 11:57:49 PM
well, i was wrong then.

I have the 8 pin connector plugged into the motherboard. I have two PCI-e cables from PSU to graphics card. I've been trying to boot with only one card the whole time.

You may have some defective hardware, then. I'm guessing the MoBo doesn't have an LED POST readout on it?

I'd try reseating the RAM, only putting one stick in, and trying different RAM slots, then reseating the CPU, then replugging all the power supply connections, and then I'd send it back if it still isn't working -- worst part is you don't know what's failing unless you can get a POST code. Rarely, MoBo manufacturers include a speaker which will beep out an error code. If you have a case, sometimes they have the speaker built into case with a wire coming out which goes into the speaker pins for a code.

if you got the mobo new in the box, it came with a little speaker (pencil-eraser size) attached with two inch-long wires.  plug it in to the speaker header, and check MSI's web site for beep codes...

It's funny because that question is answered every time the difficulty changes. Maybe these people could use the search function once in a while, you know...

Have you tried it?

Give me a search phrase that can answer this question without browsing beyond the 3rd page of results.

This may mark me as a total newbie but...
How are people setting their memory clocks? CCC won't let me set mine lower than 450MHz. Running dual 4870's.

what operating system?
831  Bitcoin / Mining / Re: help cant boot w/ 5850 on: May 18, 2011, 11:45:13 PM
Its a msi 890fxa-gd79 (w/ no onboard video i think)

http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274

yeah, there was a little rubber blocker thing, but i took it off. oops. the manual itself says 8 pin though, and shows all 8 pins, so idk

I just got one of those this week. Mine's running like a champ so far.

i've never owned that particular board - but i've had lots of MSIs.  haven't seen one yet that took all 8.  but if it worked for you i guess i'm wrong.

i'd still try it though...  Huh

nope.  you need to plug just one 4-pin in.  the rubber blocker was almost surely toward the CPU end of the board.  plug in the 4 pin connector (the one that fits - they're different.  look at the corners; some are rounded, some are square) to the four pins that are closest to the PCI/PCIe slots.

what motherboard?

frequently, only one of the 4-pin connectors gets plugged in to the CPU power connector, and the manufacturer (like; MSI) has four of them blocked off with a little rubber thingie that's prone to falling out.  read the manual for your board.
834  Bitcoin / Bitcoin Discussion / Re: Fixing the "mining problem" on: May 18, 2011, 07:11:21 PM
If the majority of bitcoins are treated as a sort of speculators tool then yeah their value won't have much of a solid base. So I personally agree with people that say that bitcoin needs to grow in economic use. This whole mining thing is blown way out of proportion. I have this uneasy feeling that mining will still be an ongoing central focus for most people until all 21 million coins are minted. I worry that a large majority of newbies are going to treat bitcoin as a cashcow (mine some coins and then dump them as quickly as possible). Heck, hoarding would be better than mining and then dumping them quickly into fiat. Even better would be to buy services and goods or offer their own services and good for them.

I do not agree with not telling people about mining though. I don't think it's a good idea to conspire to keep new bitcoin users in the dark about this aspect of the bitcoin system. It would be pretty damn hard to keep them from finding out about mining anyways. The economic incentive is there so it's hard to blame them for wanting to exploit the potential for profit.

Dare I go so far as to say that we're going to have a "mining bubble" which is going to drive up price and so on and so forth. Eventually the mining bubble will pop as the non-professional miners will get kicked out of the market by the increasing difficulty. So in the end everything will or should work out just fine Smiley

@ speeder, I agree with you, there are a LOT of miners out there that don't give a shit about the security of the bitcoin network and they aren't planning to do this for the long term. They just want to squeeze as much fiat money out of this bitcoin thing for what it's worth. I'd have more faith in the early adopters than in say some teenager with his fancy pants radeon that his mommy bought him for Christmas. It's those that have a lot to lose and a lot to gain from bitcoin's success that you can count on to be there for the system when it needs them.

Heck I'll mine at a loss if necessary! I don't give a crap about an extra $20 a month in electricity. I want bitcoin to succeed in giving a large portion of humanity freedom and control over their OWN money. On the flip side I understand that I'm probably in the minority and that not a lot of people share my ideological motivations.

C'est la vie, n'est pas?

[emphasis mine]

i more or less agree.  i dunno if i'll mine at a flat loss - but as long as i can cover my electric bill and an occasional cup of coffee i will.  i want Bitcoin to succeed as well, and my hardware was paid for some time ago.  even now, i'm keeping a nice bunch of BTC, but spending proceeds from my mining.

spending BTC is like hashing - they both secure the network, in their own way.
835  Bitcoin / Bitcoin Discussion / Re: The Bitcoin 100+ - The Internet's Richest Bitcoiners on: May 18, 2011, 12:20:52 AM
I'm not sure I understand the instructions. Are you suggesting that the person announces their balance here, then moves it to 5 other addresses so that they can post links to Bitcoin Block Explorer as evidence?

Apart from the fact that few people would go to that much trouble, there is the downside that by consolidating your coins you link their histories together. Not everyone will want this.

Atlas, why don't you show your own wealth? If no-one else shows theirs, you will be permanently ranked Richest Bitcoiner #1.

[emphasis mine]

not only do you link their history - you damage their value.  my understanding is that solo-mined virgin blocks will always command a premium price over the current market, since they are the most anonymous Bitcoin extant.  the mixer sites need those...  yes?

836  Economy / Economics / Re: What happens if the US bans the use of bitcoins? on: May 18, 2011, 12:06:36 AM
The US will NEVER ban Bitcoin. The US might pass some legislation that appears to ban Bitcoin, but in actuality it will not be banned, ever. It is an impossibility. However they CAN and might ban the purchase of bitcoins using USD or the purchase of USD using bitcoins.

ahhh... "...within the borders of the US."

the US gov't couldn't do anything about exchanges outside the US - even if they traded USD.  and as i recall, there's more USD outside the country than inside.

just ain't gonna happen.

Hmm, that site lots good- barely anything for sale on it though, which makes me think it's unlikely I'd ever sell anything.
Can you vouch for its legitimacy?
Also, they charge an insertion fee- which, seeing as I have no bitcoins, I wouldn't even be able to pay!

Any other tips?

839  Bitcoin / Mining / Re: Tips for a beginner on: May 17, 2011, 03:48:01 PM
you'll wind up with 8 connections and about 124,600 blocks.  takes a little while.

that said, mining with a CPU (instead of a GPU) is unprofitable.

"I have a certain amount of historical understanding of how fiat money acquired its value, albeit based currently on faith. But I don't grasp where the value of Bitcoin originates."

take a piece of fiat money out of your pocket.  look at it.

where does the value of it originate?  in your faith, and only there - even knowing it is completely manipulated and manipulable by forces outside your control.

now open up your Bitcoin wallet.  look at it.

faith is good - and faith in Bitcoin (that it is usable for transactions with others) is good.

but also, it is not under the control of outside forces.

better.
