Its what happens when you have too many double shot espresso's at night time. Pay attention kids.   

Honestly, its one of those "if you have to ask the question, you shouldn't do it" kind of things. Many here have tried and failed to optimize parameters. Mikaelh and Sunny King and others have already put a lot of time into testing different parameters, and accordingly the default parameters used in each version have changed throughout its development.

Immersion cool in baby oil (paraffin oil) (About $5 per liter not buying it in bulk), circulate with a quality car windscreen wiper fluid pump or electronic fuel pump. The reason for this oil choice is its availability and its not very viscous at all. These are about the same cost as a "gaming" water cooling pump but far more better quality and more robust: just get one from your local car junkyard they should have millions. Also, fuel pumps are designed to handle non-polar fluids (which includes oils) so they're more likely to be compatible with the oil than a random watercooling system pump which may contain materials that will disintegrate / dissolve / embrittle in the oil.

Get yourself a portable air conditioner, or external unit of a split system air conditioner and have the gas removed by a licensed refrigeration mechanic (of course). OR, a second hand car radiator. All of these should be able to handle over 3 kW of heat assuming you put some decent fans near it. Even with silent fans you can remove immense quantities of heat thanks to their ridiculous surface area.

Tubing should be silicone (medical) tubing or fuel line tubing that automotive and some hardware stores stock. Fuel line tubing costs about $7/meter where I live for 2 mm thick walled stuff (Masters Home Improvement centers, Australia). Medical tubing is usually even more expensive ($10+ /m) and not necessarily any better and you'll probably find stock in your country is monopolized by companies who specialize it selling it.

Before installing the system for real, you should place it over some kind of sealed basin or container and leak test the entire system with its full lengths of tubing for at least 1 day. However as some materials are semi-permeable to oils you should think about testing it for at least a week if you want to be cautious.

If you have access to a quality router with metal routing bits you can easily make your own waterblocks with a moderate ammount of fore planning their design. It should be made from aluminium. If your have a router or CNC capable of doing this work then you don't need to be told where to get metal from. You can buy silicone sealant strips or rings, and silicone sealant type glues from any half decent hardware store to make the seal.

If you dont want to make your own 'oil blocks' then you can buy the relatively large (and relatively dodgy) Chinese eBay waterblocks. I have heard reports that they CAN be used with oil.

It's also worth keeping in mind that although its VERY hard to ignite paraffin oil without preheating it to at least a few hundred deg C, it can burn. And if it starts to burn and you have a few liters of it you have a extreme problem. I recommend that any high-current cables passing through the air-water interface are sealed inside of a metal tube so that if there is a fire in those cables then it cannot contact the oil interface. It is almost impossible to get a resistively heated wire to ignite oil if it is fully submerged in the oil. It can only ignite if it manages to heat the entire oil mass to its autoignition temperature or if it can come into contact with the air-water interface. I recommend you test this for yourself with a small qty of oil and and old ATX PSU.

My ones at home are 4 to 16 GB each. The ones at work can be up to 256 GB not that this software would ever come close to using that even with 64 threads.

I installed OPs software on all my systems at home last night and ran for 12 hours. On systems with more than two threads I ran the program (with different ports and data directories) with genproclimit 2.

However... only two machines at the end of the 12 hours were on the actual current block. All the others had become confused. It was not a connectivity issue: there is no indication of a internet disconnection etc.

On primecoin this happens too, but maybe only once or twice per week, on 1 or 2 machines at most. So I am surprised to see this problem is so prevalent with this client. When -QT based clients do this, they continue to mine with threads wasting energy without alerting you to the problem, so you must actively look for it.

For those wondering, the full shortcut command to launch with low priority, a different port and data dir, and autostart with 2 threads is: (example)

C:\Windows\System32\cmd.exe /c start "runlow" /low C:\protoshares\protoshares-qt.exe  -port=17690  -gen -genproclimit=2 -datadir=C:\ProtoShares2

I too have had problems with cryptsy deposit / withdrawals. Their support is slow and sometimes does not reply, however the problems I've had were always fixed in the end. That being said, they need to lift their game if they want to compete with other exchanges.

Do these individuals like to wear leather jackets and play a lot of baseball with peoples heads by any chance?

So I have almost a dozen machines running XPM solo mining right now. But new to PTS and looking to give it a try.

Some quick questions:

- Is the software in this threads OP considered the "official" client? I'm guessing it runs slower than the forked versions. Would OP's software here be analogous to Sunny Kings official primecoin client?

- Is there solo mining software that offers the same performance as some of the optimized pool mining software referred to over the last few pages (I prefer to solo mine as it does not rely on a 3rd party server)

- Any recommendations for solo mining clients if there are forks that are faster than OP's?

Its generally better to use the chainsperday value for comparison/performance assessment. However, 3k PPS is similar to what you'd expect from a top of the line intel i5 CPU and some of the higher end i7's. So I wouldn't really call that 'low end'.

Using poor or solo mining depends only on how long you can wait between getting payouts. Its possible at around 3k PPS that you may now only find a block once per fortnight or less. However keep in mind that a block is currently worth a lot more thanks to recent interest: Right now a block of 10.10 XPM is just under $60 as I write this.

Although a lot of people struggle to understand/accept the variance inherent in solo mining blocks, my anecdote from my ~3k PPS CPU is that I have found about 1 block per week over the last month. However you need to keep in mind that difficulty has recently risen another few %. I have some slower machines that can go months without finding a block.

If you look through my comment history, or mikaelh's comment history, you will see discussion regarding the calculations you can use to estimate your mining capability.

It looks like we might be stuck in diff 9 land for a while longer...

A lot of the daily scrypt shitcoins are giving 1400 to 1500% better return than mining SHA-256 (bitcoin).

As I write this, 6 MH/s of scrypt could easily give you $500+ USD per day revenue at current market rates on several of those coins.

If you have ANY radeon graphics cards and you're not mining (at least) litecoin or one of the other altcoins then you are doing it wrong or don't like money or both.

I've been using bitcoin-qt for a while. However, there are certain websites which aggregate bitcoin node IP address and geoip/whois locations. I believe this is highly undesirable (I question the motives of the operators of such sites too).

As a result I installed TOR and setup the proxy preferences for my client, after I had my ISP change my external statically assigned IP.

I then sent ~0.3 BTC to an exchange with bitcoin-qt, it asked for my password, but it did not suggest a fee, instead it immediately sent the transaction with no fee (confirmed via listtransactions).



I notice in the preferences that it is set to not include a fee (it is set to "0.00000000 BTC" fee per kb), however this seems to be the default setting (even though this client has previously suggested fees while making a transaction previously)?

Could this behavior be related to the addition of the proxy config, which from what I understand disables "listen" in qt clients. I think that regardless it is time I move to more lightweight client, but it would be interesting to see if others are having this problem.

(EDIT: The transaction of course confirmed, but this was still a substantial delay, about 8 hours.)

People who rarely check their hardware and possibly those who mine offsite.
People who received miners as gifts (eg BE USB's) and were never really sure what the deal with them was.
Noobs who are new to mining and can't tell that there is all kinds of problems with the site at the moment.

Was there something it specifically needed or do you just like incremental numbers?

This is an excellent summary of the current situation. A+

I've not encountered this specific one before, but you could try:

- Checking your computers clock region and that the time is in sync with an internet time source (this has caused other people lots of strange problems it seems)
- Ensure the computer is stable under high load (with a CPU stress tester like Intel Burn In Test or OCCT) and testing memory with a CD/USB of Memtest86+
- Ensure your storage device containing the data files is in good health (you'd probably have many other problems if this was the cause)
- Double check any command line parameters you may be using to launch the .exe
- Delete the data directory and try again. On windows it lives in /userprofile/AppData/Roaming/Primecoin

You can skip through the blockchain download by copying the files in the path above from a machine that works. However, not all the files should be copied (eg wallet.dat). I usually only copy:



which seems to work well.

As one of the two people who posted a screenshot, I feel your burn.

However, I assume that any pool operator would be at least a little bit smart, and not payout $200k+ of coins to anyone based on an obviously corrupt database (they admit this in their news reports). So I did not and do not expect a payout like that in any case.

The mega thread with everything you need to know about block erupters and pies.

I run solo at home and also at work, but there are a lot of machines so I see blocks regularly: if you only have 1 or a few machines to mine on then pooled mining might be better for you.

I personally doubt that any pooled mining client will be faster at finding blocks than HP11.

I have tried a couple of the pools but dislike relying on a 3rd parties servers.
