I doubt they're a scam. You should be fine. They're just taking longer than expected.. to say the least  Roll Eyes

Well, have you read the wired magazine article?  I mean, it's not some mickey mouse publication here, it's wired.  I really hope it's not true cause I already paid and I doubt I can get my money back.  Cause without those asic machines I don't see an affordable option at this point with the difficulty where it is.  I can't even mine decent litecoins and their difficulty is only about 480. 

can anybody chime in on BFL?  TIA

I've been doing a lot of reading on devcoins and I find some interesting things about it and I think it's only a matter of time before devcoin really takes off.

I would like to add my thoughts and contributions on the devcoin main thread and it appear that you actually get paid for writing articles and such for devcoin.  But how can I do that when I'm now allowed to post anywhere except this newbie thread.

Does anybody know how long before a newbie like myself gets bumped to Jr level so I can post on other threads?  Is there a time limit or if you post enough quality posts will that work?  TIA

10,892 mh/s
1x Block Erupter

so you're getting 1 GH with just one video card?  Sorry but I've never heard of block erupter, is that an ATI card?  what about the rest of your setup, can you elaborate and perhaps add the cost of the equipment as well.  thanks

A pathetic 27MH/s on a ATI Radeon HD4600 Series.

Eyeing up a 7850 for future purchase.

Just last week I returned a dual 7850 new computer with an AMD FX 8350 8 Core chip, 140 gig Samsung 8400 pro solid state drive, 8 gig of ram a 1200 watt power supply (paid $1700 with windows 7 Pro at Frys, and lost $300 2 days later when I returned it) and all I was getting on litecoin was 300-500 kilo hash and there's about a 1,000 fold increase for bitcoin mining hashes so I'm guessing I would have gotten 500MH.  For $1700 and the cost of probably around 800 watts running 24/7 that's just not a winning solution in my mind.

There's some real veterans here who have seen all types of systems and cards - can someone spell out in simple terms what the best way is to go as far as hardware and energy costs.  1 time costs I can stomach even if I have to get 4 video cards, but if I'm gonna spent $250 per month on juice just to make $500 with no guarantee the difficulty won't sky rocket when the BFL units hit the street in the coming months, then it's just not a good return on investment.

I have a question for the experts here.

If you get a rig with 2 or more graphic cards is it better to crossfire the ATI cards?  What I mean is, I've heard you lose efficiencies when you load more than 1 card in the same computer, is it better if there's 2 or more GPUs acting as separate units or is it better if you crossfire them so they mine together as one?  I had my 2 7850's crossfired and it was weird, on litecoin I was sometimes getting 300kilo hash and other times 500 kilo hash.  that's a huge difference.  and on top of it, each card was rated at 350 kilo hash so was I losing that much by having them run in the same computer?  Cause if you lose close to 50% in GPU efficiency it's almost better to buy a cheap $300 computer and run the second card by itself.

Do not crossfire them there is a slight performance decreas (at least on my 7950's and 7870 tahiti's).

Thanks, that makes sense.  The guys at frys should have known better.  I told them I would be using the rig for mining on top of other things.

Best choice now would be to go for 7950s and mine LTC.

I agree bitcoins are hopeless at this point unless you have a huge setup.  But even litecoins, for some reason with a dual 7850 setup and new FX 8350 CPU, high end $1700 setup I wasn't even getting half of a litecoin per 24 hours.  So that's around 2 litecoins per week or 8 per month.  So you spend $1700 and run a hungry computer 24/7 all month for 8 coins or roughly $35.  That's nuts.  I'm sure electricity on a rig like that alone costs more as my unit had a 1200 watt psu.

So what am I missing?  Why are there so many people here banking coin and I'm not?  Or is everybody else just thinking they're making a profit cause they haven't done the math?

What does it take to become Jr member?  I would really like to post on other threads like the devcoin thread but can't.

Mining about 400 Mh/s with 7870XT. BTC have mainly being my pick, while tried some LTC mining but results were rather poor compared to BTC.

That can't be right I've been posting for over a week and have 20 posts and I'm still a newbie.  Maybe they consider 4 hours having to actively search through posts.

I'm running a HD Radeon 6770 at ~130Mhash/s and a laptop at ~1.5Mhash/s

Using pooled mining because fuck competition.

What are you running?

I'm running a HD Radeon 6770 at ~190Mhash/s

Very wrong settings you have. I mine almost 0.5 litecoins/24H with Radeon HD 6770

I've got my 7870 (gigabyte 7870 OC) bouncing between 490mh/s and 550mh/s. temperature is around 58*C to 63*c, which inturn runs the fan from 38% up to 68% between those temperatures.  It's consuming around 140w/h.
