can someone explain the 8.04 / 440s?

I thought the network solved (ideally) 6 blocks an hour which would be 6.00 / 3600s ?

I'm one of the newbs who got a bunch of 6870s and have em running.. 3.6 gigahash installed, and im calling newegg monday to see what i can return unopened.  I may keep a small farm going just for shits and grins but at chicago power rates of 15 kWh and 20% difficulty increases every 14 days I will never recover my costs (not even close).

Extra equipment i bought:

700$ electrician work, (individual circuits, breaking out circuits near a window for good airflow, etc)
100$ various fans
50$ tables/benches
80$ 16 port switch
10000$ computer equipment (6870 radeons, motherboards, semprons, 1000w power supplies, PCIe risers, ethernet cables etc)
40 hours work setting it up
(insurance, risk of fire/flood damage, massive heat generated, the 50 flies that are in my house because i opened a window near my set up to deal with heat)

Chicago electricity:  15c/ kWh (this is my #1 cost and its MAJOR)

Basically I'm in hell.. I'm praying for a miracle and all i see is MORE posts about people buying 6990's and other cards that are even LESS efficient than mine.. and I now realize that i'm basically up against a bunch of enthusiasts who really dont care about the economics of this at all, they just think its 'cool'

If anyone needs any of this equipment please make me an offer near newegg type prices, I will give advice on how to set it up, etc.  You can pay me paypal, bitcoin, cash, however.  I would like to move this stuff in bulk if possible, if you are planning on starting an operation or are a reseller, etc.  

I can help with running it, I have a about 3.5 gigahash mining right now rest is in boxes, unopened.  If you are in a lower cost state or mooching off a college campus you can probably run this profitably.

so as I understand it you're only vulnerable if you're compromised by another site already?  Why dont you clearly state what actions can make you vulnerable instead of making people think that mtgox has a virus on it or something (which is what most 'regular' people woul infer from this)

common sense would dictate that the price will quickly move to the lowest common denominator which is someone living where electricity is 'free' (dorm room, IT techs, kids in basement) etc, with people who dont factor in depreciation at all (gamer who would buy the graphics card anyway), and someone who values his time at 0$/hr (an enthusiast, someone who enjoys working on gaming rigs).

Factor in these 3 costs, 0$, 0$, and 0$.. and it takes very little to keep some sizeable hashing power online.  Consider 'folding@home' which reached 8 Petaflops with NO monetary incentive.  And I think you can see the future of bitcoin mining...

And people dont realize how quickly exponential decay destroys margins.

Please, if you live in the chicago area I have plenty of high end mobos, power supplies, radeon 6870's, i will sell at reasonable prices. 

Truth is i went gung-ho an set up a buncha rigs myself.. and i'm regretting it already.  I did a spreadsheet with minor 20% difficulty increases every 2 weeks (which is very optimistic) at 20$ a bit coin, and its a loss.  And if bitcoins get hot again, and prices shoot up, we'll just get more 30%+ difficulty increases.

The fact is there's enough kids with graphics cards who will run the miners part time at no electrictiy cost (college dorms) to overwhelm the current network of about 30,000 GPUs.  I'm in chicago and paying 15 cents per kilowatt hour.  What ends up killing the profability is electricity, depreciation of equipment, and difficulty increases.. not so much the value of bitcoins themselves.  If you do believe in bitcoin appreciate then just buy the bitcoins themselves.

My partner has dropped out and if anyone is in the chicago area and wants to buy some 6870's please private message me.  It's not a realistic business plan to compete against a miner who's 'happy to pay off part of his graphics card to play the next cool game'.

On the plus side i got all rigs running and fully operational, very sweet set up, i may take pics.

namley i could NOT get ubuntu to boot on the MSI just FYI...

I'm NOT using dummy plugs on any of my cards, but linux does recognize 2 cards even without monitor switching.. Maybe dummy plugs would make all these problems go away?

using the 890FXA lines from both biostar and MSI, and i always have trouble running more than 2.  I'm using either 4x5830's or 4x6870's in my setup.

The biostar has alternating pci16x 4x 16x 1x slots.  The 16x are red and the 4x,1x are white, the white slots are real close to the red slots so its impossible to put the cards side by side, so i use risers.

Everything is fine as long as im using one from the first 2 and one from the last 2, but when i try to put a gfx card in a red slot then one right next to it in the white slot (with a riser) it fails.

MSI has enough board space to allow all 4 to fit fine (jammed together but fits), but again same problem more than 2 and caput.

I'm using a 1080 watt Xforce power supply it has 4 12 volt rails with 20+amps on each rail, so should be ample power.

The funny thing is when i boot ubuntu on the biostar with more than 2, it frequently has weird behavior like artifacts, and the login window doesnt appear but the purple background does, etc etc.

Anyone have any ideas?

so the 'source' for this 'true story' is bitcoinmining.com?  Is that like a division of CNN?

ATI overdrive software with the default BIOS lets me do 600-875 on the gpu and 900-1200 on the memory
what kind of hashes can i get without flashing the BIOS

and where can i get the flash software to flash the better BIOS?

i dont care about running them hot i've run radeons hot for years and they never burn out

Thanks fellow bitcoin-rush miners!  The flags got me to aroudn 255.. but when i tried installing the 2.1 SDK (win7 - 64 bit) guiminer gets stuck at 'starting...' when i try to mine.. so my hash rate is now 0

anyone got any ideas why 2.1 SDK screwed things up?

running at 400 mhz mem clock, 875 mhz GPU using the ATI overdrive
using asus m3n7d-2 mobo with phenom x4.

Miner: guiminer, no extra flags (they dont seem to make a difference)

any reason why its so low? thought this was sposed to be sexy 300 megahash monster.

is it cuz i skipped the hash browns at breakfast this morning (too many carbs)

i was on the phone with their corporate sales when they went from 200 to 0 within about an hour after some tard posted it on here.

Newegg similar story.. I got some from them, but sell out very fast.. even checked some contacts in china, stores with inventories of 300+ being cleared out instantly.

I shudder to think what difficulty is gonna be in about a week once the 3 day shipping windows are up

For the record, I'm buying, and mining, because I believe that we're in the early phases of a bubble, and there's plenty of money to be made in bubbles.  Also, I think that buy-and-hold'ers will make money if they can weather the volatility.  But to those who are deluded that this is gonna be a smooth parabolic rise to the moon, NO.

(my belief, no proof).  To arguments about the validity of the mythos currently surroudn bitcoins, I say 'it doesnt matter - bubbles arent about logic, they're about greed and fear.. thats all'

and  i think fundamentally we're in agreement.. BUY BUY BUY!!!!

oh i agree... I'm not selling by any means.. im buying.. i think the price goes over 100$.. still early phase.  This is a bubble in its very early phase.. and even after it pops, there will be a dead cat bounce at which point i will sell.

actually its you who doesnt get the concept of a bubble.  You are spouting the classic 'this time its different' line.  Everything you said can be perfectly true and still lead to a bubble, actually most bubbles are founded in very real and accurate logic.. 'tech is the future', 'god aint makin' anymore land' etc the problem is when price action accumulates years of "new paradigm" in a matter of a few weeks/months, and the collapse is not necessarily caused by the failure of a technology to live up to the promise, its true cause is PANIC, people simply can not watch millions of dollars go to 0 without selling, and no matter how intelligent a crowd is if a fire starts, they will trample each other to death.

This IS a bubble, and there will be a huge crash, but that DOES NOT mean that bitcoins are a failure, it will just take longer for it to happen.  I mean tech didnt go away.. eventually amazon.com did live up to the promise of 2001.  IT just didnt do it in in 3 weeks while the public was panic buying to get rich.


O

so basically yer sayin what came first the chicken or the egg

uh q q q q thats some fancy talk for somethin that anyone with some farmin' sense already knows natural

so where's Satoshi in all this? Isnt he the creator?  The mastermind? .. so a buncha white-collar techie sell-outs co-opt this thing without even comprehending the spirit of it all?  Just because it's peer to peer doesnt mean it has to be EVIL.... we can take it upon ourselves to know who we're doing business with and report the drug dealers ourselves.

If the people behind this dont have any kind of idealism or ethics this thing is just gonna turn into another fee-based thing which will charge 0.001% less than the banks (until theres a 'meeting' with the bank which will oddly result in fees being identical or just an outright sale to said bank)

Fine.. I understand.. your scared of the big bad all-powerful government.  But why surrender before the fight has even begun?  If they reall wanna go down bashing in doors and arresting pasty-faced geeks at their computers then throw in the towel but dont just hand it to em on a silver platter.

this is the equivalent of a mafia foot soldier visiting the feds 'just to chat' or the head of the nuclear program visiting iran 'just to give a presentation'

Honestly... way to sell this whole idea out.   It's one thing to tolerate the CIA but another to get right into bed with them.  Noone is saying to flout the law, but somehow I dont think that martin luther king would have gone to a clan meeting cuz he got paid 3000$.

Do you HONESTLY think these guys are fascinated by the intellectual curiosities of this like little school children?  

Sometimes a little passive resistance is CALLED for.. there's enough people selling out to the CIA they dont need YOUR HELP.

anyone got the formula?
With current difficulty, of course

I can see it now... untouchables raiding poor hicks in the south... is that a 5800x gpu i see?
BIT-LEGGERS!!! smash the BIT-STILL!!
