You're going to wait a while, unfortunately.  The current difficulty for finding a share in p2pool is 11097489.31.  At 202GH/s, that means your expected time to find a share is 2.73 days.

Plenty of choices... The gridseed orbs, fury, black widow, terminators... The fury is a decent little entry level kit... About $35 or so.

The guys who make the hardware and also mine with it.  They're the ones making the lion's share of the profit.  You and I can't compete with that.

I'm not saying mining is absolutely in no way profitable for the home user - it just becomes more and more difficult to squeak out the profits as time goes on.  You basically need to be lucky... you need to get the hardware very early on in its existence, you need for the difficulty to not rise too much during the early stages of mining with your new hardware, etc.  You need to do a ton of research and pretty much be in the right place at the right time.  So, it's just far easier and more efficient to answer "don't bother" to most everyone, simply because most everyone asks, "What's the best miner for me to buy that will get me the most profit?"  Just like the OP of this thread.  He wants to get into mining and thinks 1GH/s is a good start.  Maybe over a year ago.  Not now.  So, that's why most of us answered the way we did.  Heck, I even told the poor guy to walk around looking for spare change on the ground as it would net him a better profit.

Since you've made the changes, can you log into the miners?  In other words, they're visible on your network, and you can play around in the web configuration and/or SSH into them?

I owned an SP10.  Spondoolies has been a great company to work with, and their gear is top notch.  I have personally spoken with Guy (their CEO) a few times, and have worked with Zvi (their software guru) to ensure my miner performed at peak.  Nothing but kudos to these guys for their hardware, and their customer service.

I did not get in on the SP30 group buy, and honestly, I'm glad I didn't - the machines unfortunately came back at much lower than expected rates with higher power consumption.  Here again, though, I need to give the SP guys a tip of the hat because they are working with people who ordered the machines to give them compensation for the differences between the actual machines and the initial specs.  If the SP31 was coming out early next month instead of in October I would have snapped a couple up.  For now, I'm running a bunch of S3s.  We'll see what the next few months brings... maybe I'll be in line for their next generation gear

Are your Antminers configured using static IP addresses?  if yes, you'll have to change them to match the new subnet 192.168.0.*.  If you're using DHCP, then rebooting them on the new network they should pick up the new 192.168.0.* address on their own.

Sorry to be so harsh with the answer.  I just want to make sure you don't go into it thinking you're going to be able to mine with your PC, no matter how much of a beast it might be.  I guarantee I can hand you a little USB miner that will blow the doors off of the best computer you can buy.  Then, I'll show you a miner that will slaughter that little USB device.

If you're really interested in mining, there's a bunch of hardware out there for you to look at.  Your PC is not one of those pieces of hardware

You absolutely, positively, without a doubt CANNOT use an Antminer U2 to mine scrypt coins.  Period.  The Antminer U2 can only ever be used to mine SHA-256 coins.  That's all it can do because the ASIC has been built to do the SHA-256 hashing algorithm in the hardware.  That's all the hardware does, and it's all the hardware understands, and it's all the hardware will EVER understand.  It can't be reprogrammed, or reasoned with or bribed.  Nothing you can do or say to it will change the fact that it can only deal with the SHA-256 hash.

I hope that helps clear up that little misunderstanding

If you've got any other questions, I'd be happy to help.

Ahhh... your U2 will ONLY mine SHA-256 coins (Bitcoin, Namecoin, MazaCoin, etc).  It will not work at all on Litecoin, Darkcoin, Dogecoin, etc because the hashing algorithms are completely different.

I actually run U2s at home connected to a Raspberry Pi.  Every now and then I'll mine some alt coin, but typically they're "playing the lottery."  In other words, I've got them solo mining Bitcoin hoping to get lucky and solve the block and get all 25BTC for it.  I do it because the total power usage is negligible, and they were one of the first hardware purchases I ever made

I should have specified that CPU and GPU mining of Bitcoin is dead.  As RodeoX posted, profitable Bitcoin mining is dedicated hardware setups with very cheap power costs.  By the way, nice picture

Litecoins, and other coins based on the scrypt algorithm are also now in the realm of ASICs.  Your 300-400MH/s GPUs won't cut it - you can pick up a 1.3MH/s Fury for less than $50 with power supply and cables.

Your only chance, if you do insist on using your CPU/GPU is to find some alt coin that uses an algorithm that is not yet ASIC and hope it takes off.  Otherwise, you'll need to buy a dedicated mining rig.

I really do wish I could be giving you better news, but that's the reality of things.

I have no affiliation with NiceHash (or WestHash); however, I can confirm they actually DO mine.  I know this because I ended up with about 70TH/s on my p2pool node from them.  No idea how they even found my node since I don't promote it (but I do leave port 9332 forwarded so I can look at my stats from the road), but suddenly I had a new miner on my node with a pretty significant hash rate.  When I looked at the traffic, I saw the IP address and it was owned by NiceHash.

Anyway, that's just my 2 bits on NiceHash.  I've checked out their site, and it's pretty interesting.  Basically if you own hardware, you configure it to point to their pool.  You also put out orders for people to use your mining power.  If somebody buys hash rate, and NiceHash decides to use your hardware to satisfy that order, suddenly your miners are running on their pool.  If nobody is using your hash rate, the pool appears "dead" to your miners, so they go to their fallback.

Honestly, it's about the most interesting "cloud" mining solution I've seen yet.  It's distributed because it relies on your hardware, and it actually mines on real pools.  I haven't checked out their pricing or fees, so I can't comment on it.

I'll save you some trouble.  Stop what you're doing.  You cannot successfully mine BTC with your computer.  Period.

The days of CPU mining BTC are long since over.  The only thing you're going to get is a huge electricity bill and potentially shorter life of your CPU because you're going to be running it at 100% constantly.

In general, yes you're heading in the right direction by downloading the core software, creating an account at a pool and creating an account at an exchange.  Now you just need to purchase a miner.  Your computer is worthless for mining.

Perhaps you might be willing to share a bit more detail?  Thus far you've successfully ranted and raved about how you know nothing about computers and can find absolutely no instructions anywhere on how to do anything.  Hopefully that's out of your system and you can start discussing some things rationally

1) What hardware are you using to mine?
2) What coins are you trying to mine?

I see you mention scrypt a few times.  If you're looking to mine alt coins (i.e. not Bitcoin), you're in the wrong forum.  If you're trying to mine Bitcoin, you're using the wrong algorithm (Bitcoin is SHA-256, not scrypt).

They offer the hosting as a convenience, and yes I agree they price it extremely high.  $500 a month is a tough pill to swallow since there are far cheaper options elsewhere.  They don't have the capacity to host a ton of miners.  They've come out and said as much on their thread, which is why they initially partnered with the facility in Washington - further supporting my point that not all companies are pre-mining their hardware before sending it off to customers.  I'm quite sure that Spondoolies didn't ship a boatload of SP30s to Washington, mine them for months, and then decide to ship them back to Israel to send to customers.

Don't get me wrong, I do indeed believe there are companies doing exactly what you're accusing those companies of doing.  I also agree that your average consumer doesn't have a snowball's chance in hell of competing with the guys who are producing the rigs if those guys are also mining with them.

OK, good .  Now that we've cleared up you're plugging things in properly, I fall back to my original post here: I wouldn't trust the PSU.  If you're plugging in only 2 PCI-e cables and it trips the PSU, something's off.  It looks like you tried another PSU that exhibited the same behavior at first, but has since run properly?  What kind of PSUs are you using?  I've got EVGA 1300 G2, Corsair HX1050 and a Corsair CX600M that I use and have not run into issues like you're describing.

OK... another question for you that may seem obvious: are you accidentally causing this on your PSU somehow (like, are you using the old paperclip test, and that clip slips out or shorts or something)?

Are you truly thinking about only 1 gigahash?  Did you mean 1 terrahash?  Maybe I should rephrase this... how much are you looking to spend on your initial hardware investment?

If you were serious about the 1GH/s, if you had that mining for you right now, you could expect to earn 0.00002109BTC per day, which at current conversion to USD is just about $0.01 a day.  Unless your electricity is free, and the hardware you're planning to use was also free, you should really re-think getting into mining.  Even if it IS free, you should re-think getting into mining.  I'm pretty sure you'd be better off walking around and looking for change on the ground.

I don't think it is.  I'm pretty sure that when SP first came on the scene, that was the URL they provided.  Also, the URL you can use to detect the SP gear on your network is myminer.io.

I'll certainly agree there are SOME manufacturers doing precisely what you're stating, but it is not all of them.  Spondoolies, for example, sent their first SP30s out in July.  If what you say were true, then they'd been mining with those SP30s since May - which simply isn't the case.  They never even received the first of the Rockerbox chips until July, at which point they realized the chips were way off of the specs they had simulated (promised 6TH/s got 4.5TH/s with higher power usage).  Same with Bitmain's S3.  That machine went on sale June 30, so according to you they'd been mining them since April.  Initial specs for the machine were 504GH/s, later reduced to 478GH/s. The actual released machine was 440GH/s because of lousy DC/DC converters.

I'm not sure how much I believe that the network suddenly spiked 50PH/s in the past 36 hours.  The network hash rate showing on other places is currently at or around 185PH/s.


Even if Bitmain has secretly developed the S4, do you think they have the capability of deploying 15000 of them at once?  They just happen to have a 20MW facility sitting around idly waiting for them to throw hardware into it?  BFL?  Please... they couldn't hit the ground by falling, let alone suddenly throw that kind of hash rate out there.

Let's all relax and see how things are evolving after 1000 blocks or so.
