I don't mine because i really don't believe that any Hasrate is enough to gain profit.

so I got an older dell server with 2 quad core 2.5 ghz L5420 and I tried to use cpu miner but it's pretty much worthless.  I then tried to mine litecoin since that's CPU friendly (supposedly) but Im only getting 40 kilo hash on litecoin.

can this be right?  I disabled the step technology in bios so the cpu doesn't slow down and it didn't do anything.  I'm running windows 7 pro.  any ideas, is it possible only 1 cpu is working?  I just can't believe 40 kilo hash is all i'd get from dual xeons, even if they are a bit older.  the ram is 16 ECC  gig, and 15K scsi drives which of course make no difference.  I guess I can install a GPU but then energy cost is gonna go through the roof.

Any ideas would be appreciated.  I read that a 4 way mining program works great for cpu mining but I couldn't find any 64 bit windows 7 ones that would work on my server.  the server came totally wiped  clean so I spent all night just loading some necessary software so perhaps I'm still missing something.  I did install Open CL from the intel site and other important drivers.

On a side note, because I can't yet post on the devcoin thread, how do I get a devcoin wallet?  I installed the software but what pops up is a window that says bitcoin address.  this can't be right, correct?  It's confusing cause I have a bitcoin wallet and litecoin as well on the same laptop.  thanks in advance.

You know, I've been at this about 30 days now and I've spent some money and i'm starting to feel the same thing.  I can't even effectively mine the cheaper coins like namecoin or litecoin.  It's getting ridiculous, but I'm still trying to make something work.

I even ordered 2 5GH units from Butterfly labs and now I just read a wired article which says it's  total scam and that they don't work as advertised.  What do I do, they already took my money out of my paypal account and their website says no refunds.  What BS.  can anybody confirm if BFL is really just a scam.  I wish you could use their units for mining other coins, that would be worth it since mining bitcoin is pretty much a lost cause right now unless you have a killer rig and free energy.

thanks in advance.

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

hold on.  you're running 18 graphic cards?  can I ask, what setup do you have?  I've read once you put more than 2 cards in a computer you lose a lot of performance so do you have like 9 computers you're running?  also, if that's the case isn't your energy bill at least $500 per month - and how much money can you clear?  I checked the bitcoin calculator and even at 10GH you're only making about $40 per day.  seems like a huge investment for $800 per month profit.

Am I missing something here?  I'm looking for the most efficient way to make this work and I can't seem to find anything reasonable.  And I don't even care about mining bitcoins, I see that as a boat that sailed away, I would like to at least be able to mine other coins like namecoin or litecoin, devcoins, etc.

Any advice would be appreciated.  TIA

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

[Vlad2Vlad]

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

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

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.

[Vlad2Vlad]

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.
My 2cents

[Vlad2Vlad]

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?
