You'll probably never recover your initial expenditure of $600. However, depending on other specs, getting a G7 for that price is probably not too bad. You can possibly resell it for more than that in the future (on eBay) when you're done mining with it.

How much power consumption at 100% load? I hope your running it at work where that doesn't matter. Also, noise.

Solo or pool depends on how long you can wait between payouts. I'd probably just aim for solo.

Although the number of cores sounds impressive, like many people here who've gotten high-core opterons you may be disappointed with the overall performance.

At 100% load what is your chainsperday in HP11? From there you can estimate how much coin it will generate and how quickly it'll start paying itself off.

"Bitcoin" is a danger word to eBay/paypal. They've even circulated internal emails (that have been leaked) saying that the (currency) is high-risk in their eyes, which carries many implications especially if there is a problem with the transactions between the seller and buyer. It does not matter to them if the transaction is made using bitcoins, the trade is for buying/selling bitcoins themselves, or if its bitcoin related hardware: it's all the same in their eyes.

Sellers might be able to get away with it if they don't specifically use the word 'bitcoin' or 'BTC' in their listings.

EXAMPLE:


You must then test the address by importing the privkey and then testing it with a (small) quantity of coin.

Well if you have the hardware (no investment / capital cost) and free electricity (no operational costs) then yes, by definition you are mining with 100% profit.

Will you make A LOT of money from it? No. (Probably a few cents or tens of cents per day on average). You'll also want to look at pooled mining.

A statement for which you can provide convincing evidence for, I am sure.

My comment above has nothing to do with the discussion about GPU. You are confusing two different discussions going on in this thread simultaneously. The formula I provided is one determined by the work of mikaelh, who is the author of the HP series of miners. I realize you are fairly new and may not have read all 170+ pages of this thread, you would've come across it many times if you had. The formula provides an accurate representation of the mining reward when using CPU and when assuming zero variance, eg. an average over a long period of time.

---

I suspect you are in fact trying to subtly manipulate the markets by stirring up the "IMPENDING GPU MINER" hysteria (again) that serves to create sillyness in the altcoin exchange trollboxes and market instability in general.

I am putting this down to another piss-poor attempt at market manipulation until some code is released and verified as working by other miners.

My special botnet that virtualizes the hosts CPU cores without them realizing, infects even and divisible numbers of machines/cores, is limited to spreading inside just one room, and effects only E3 series Xeons. Yes.



 

Great discussion it will be interesting to see how this plays out over the next week or two.


This would be good to have in the FAQ on the OP since a lot of newbies seem to be in denial about how hard it is to mine these days.

I have 192 E3-series xeon vCPU going offline today, maybe it will make the diff 0.001 lower for you guys 

8.0754 * 0.8 * 0.04 = 0.26 blocks per day (no variance) = those results are completely as expected = deal with it!

Edit: Apparently this old method of estimating blocks/day is outdated: ref: https://bitcointalk.org/index.php?topic=255782.msg3487226#msg3487226

Keep in mind scrypt is just one of many dozens of scrypt based coins, and litecoin certainly isn't the most profitable to mine most of the time. Very nice setup by the way I'm sure it brings in some good coin.

Holy crap, why did I do a masters degree in the physical sciences? I'll be in the nearest corner, crying to myself.

Yes. the fractional difficulty is currently very high (.96 or more) This means only 4% or less of the chains suggested by the chainsperday value would be accepted by the network.

If my understanding is correct, when we hit 10.000 diff, then the chainsperday value will change to a much lower number since its related directly to the whole integer value of the difficulty.

If you only have one (or a small few) machines then you probably wont see a block each day anymore.

This has come up in previous pages. The answer is: its complicated, and difficult to achieve.

The calculations to estimate your XPM per day have been discussed quite a bit by mikaelh and in my own posts, suggest you look through our comment histories for examples.

29 miners running here and never seen that error? Maybe I'm lucky.

Have you stress tested your system to see if its actually stable? You seem to be having a lot of unusual problems.

Many quiet fans != noise

Sound intensity does not scale like you think it does.

Wifi is unreliable. You can't VNC / teamviewer / remote desktop into a machine that has a wifi adapter that's deciding not to auto-reconnect. For this reason all of my primecoin miners ( 8 ) are hard-wired on 100/1000.

Also if something happens during POST or boot up, or a hang/wait on shutdown, and you dont have KVM connected, then you're screwed.

(Wireless KVM systems are in my experience: annoying, poor quality, buggy, laggy, and expensive).

After ensuring your time problem(s) were resolved:

1) Append the following to your shortcut path field or batch file. If you run the .exe directly create a shortcut to it


Run it

It will attempt to reindex the blockchain, but probably crash immediately. Close the program, remove the -reindex parameter, and run as you normally would.

It should now reindex the blockchain (could take a long time depending on your machine specs).

Installed any 3rd party security or network management software lately?

Check Windows firewall exception exists for the relevent .exe's in their current location. These can sometime be reset with windows updates or if the file location changes (although Windows Firewall itself would suggest that these problems should not occur, they can..).

And,
