Correct me if I am wrong, but no exchange is currently trading STR?

whatever happened to primecoin? The price is crashing like pit.  The price has been trending down the last few days because bitcoin raised in value ~10 USD recently. The change to below 0.0050 BTC/XPM is because someone sold 20k XPM. 20,000?? When/where did that happen? I don't see where anyone even sold 1,000. But I'm just looking at Vircurex. Vircurex is a very small XPM exchanger. mcxnow is has orders of magnitude more trade volume. FYI: http://www.cryptocoincharts.info/#jump-xpm-btc |

This coin is currently #1 for profitability on coinwarz... now I see why. Moving on!

Sunny I like the simplicity of the home page. It does not spam you with endless info like some other cryptocoin sites and looks very clean. And yes the truck icon is amusing! |

HP10 definitely more faster than HP9, I think the diff will going to 10 very soon.
I also selling my AWS $100 Credit, PM me with your offer.
I kind of doubt that. It looks like Diff actually fell a tiny tiny little bit recently. And it's near the end of the month, with a GPU miner looming around the corner. I think we'll see a lot of monthly payment VPS miners getting off the train in the next day or two. Much too risky to invest in another month of payments. I bet we won't see diff 10 until GPU miner comes out. I would think that almost all VPS providers would be billing each month on that users sign up date, not the start of every month. So we'd be seeing changes continuously throughout the month if this was the case. But in fact we see diff is still rising each day, if only slightly. I refuse to change my mining operation or mining plan on the whim of the possibility of a chance that there might be a GPU miner coming out. I will believe it when I see it. |

Some info on ROI / break even from my existing two BEs.
Each is currently pumping out 0.00367018 BTC per day at ozcoin pool using POT (pay on target) which is only slightly below what DGM would pay out.
At 0.17 BTC each, it would take you 46 days to make back that investment. This disregards power consumption and future increases in diff, which will probably +10-30% per every 2016 blocks for the foreseeable future.
So I think that these will probably pay for themselves within 3-4 months at current prices. That is pretty good I suppose...

got my first block on hp10 with stock settings after 3 days, mining on a core i3 with -1 idle priority (usually, when I leave the computer, I find a block). but i'm keeping my PC turned on 24/7, not doing really well.
Then consider yourself lucky. I spent three days without a block on an i7 3770k. I have given up for the moment. I have gotten improved performance since the hp10 update on my desktop. I got two blocks on the 26th and one tonight on my 3930k. Before that I was just getting a block every four or five days. At the same time, it could still be a lucky streak since I have had mixed luck mining on it previously. That's a great sample size and statistical analysis you've provided there. It could've easily been due to variance (luck) alone. I wouldn't read too far into it. |

has anyone tried Xeon L5639 yet  is it worth to buy at ~ 90$ ? Is it a 1366 xeon? Then yeah, it's quite decent. yes,it is mg]http://img03.taobaocdn.com/imgextra/i3/41935106/T2LXMIXaVXXXXXXXXX_!!41935106.gif[/img] with 10 L5639s (df and oced to 3.6Ghz),how much income from mining XMP Quite a bit, I wouldn't dare to speculate on a quantitative figure. At least a few blocks a day on average. Question is, can you make a return on it, since it looks like (based on the the OS, W7?)these CPUs would be running in 'desktop servers' that you probably purchased. |

[2013-08-27 15:31:58] Staged work underrun; increasing queue minimum to 2 That's to do with the 'queue' parameter in the miner client. Either set it to a very high number (~1000) which will use a lot of CPU (relatively) or set it to zero (0). It is not really a 'error', it just seems to be with the rate the client goes through work units. |

Having said that, I do find it very frustrating not finishing things, so if you do have any other ideas I would still quite like to hear them...  Maybe try a fresh OS install as well. I am not sure. Out of interest though, how did you generate those amazing addresses in your sig? Presumably those were case-insensitive searches, but not using RegEx? If you don't care which letter of the alphabet is repeated is the slow-down from using regex worth it for the increase in potential matches? Or do you just specify a long list of strings to match in a text file? Also, is there a limit to the number of things you can put in the text file? And do these obey the case-insensitive switch or are they always searched for exactly as written? Well you're just full of questions arnt you  I generated them with very long strings of patterns typed out manually and with CTRL+C/V Yes case insensitive is best in most cases Not regex Listing too many patterns does have some performance hit but I often run with 30+ patterns I dont use a text file, I have a long list of patterns that I paste into the command line and so they follow the case insensitivity |

For example, what do you think would be faster:
A server with one dual-core AMD Opteron CPU @ 2.4 GHz
or,
A server with two physical intel Xeon CPUs, each single core, with hyper threading @ 3.6 GHz
As it turns out, the AMD will GREATLY outperform the intel CPUs.
I respectfully disagree, sir or madam. I believe Intel has been ahead in the CPU race since the core 2, or even the core duo, and since the i3/5/7, they have been getting further ahead. Including instructions per clock. I am not saying that one company offers superior tech to the other. I am just saying that generally speaking, especially from a historical point of view, AMD tend to do more ops per cycle. Of course there will be exceptions though, and I admit I am not really familiar with the models from either company that are less than a year old. |

Some stats for hp10 :
2 x Opteron 2376 = "chainsperday" : 2.54092020 <- Really old CPU
1 x Intel i7 3770K = "chainsperday" : 2.77305771
Still no blocks found though in almost 24h.
Hope others will share their stats so we can build a nice performance thread.
It would not work well, because it varies with difficulty. --- I'm fairly certain that HP10 does NOT find blocks at 2 x the rate of HP9, despite the 2 x increase in chains per day value. About an hour after HP10 came out I spun up 500 x 8 core VPS instances and ran them for 6 hours. That was ~1000 CPD. I'm aware that the diff is now rising which will skew things, but in that time I got about the same block rate (average 4 an hour) as I did when I last tested a week ago with HP9 when diff was 9.75. Allowing for some luck variation (which should be largely eliminated due to the high number of instances), I can say it is not twice as fast at finding blocks. I can't say how much faster it is without more testing, which I'm not doing as running those 500 instances is NOT profitable by a long way My limited anecdotal experience suggests that same: it's not really ~100% improved mining. It sounds too good to be true anyway, but I'm sure the optimizations help somewhat. Out of curiosity how much did those 6 hours cost? Also we would expect to see changes in network diff and blocks found if there was really such a huge improvement from HP10: http://192.241.170.170/ Instead we see this is not the case. |

I run 3 computers with shitty Athlon II X4 640s and together they seem to produce a block every 2 days using the latest hp client. Individually they seem to out perform my main computer with a mid level sandy bridge i5. Are AMD CPUs better for xpm mining?
Probably not. I will leave it to OP to confirm support for various instruction sets / types. A lot of people think an AMD is 'better' than a intel CPU because they arn't aware that AMD CPUs complete more computational operations per cycle than intel CPUs. This allows them to do 'more work' in any period of time compared to a intel CPU, even one that has a faster frequency (GHz). For example, what do you think would be faster: A server with one dual-core AMD Opteron CPU @ 2.4 GHz or, A server with two physical intel Xeon CPUs, each single core, with hyper threading @ 3.6 GHz As it turns out, the AMD will GREATLY outperform the intel CPUs. --- In reality even comparing frequency is meaningless now. There are other important differences like bus / HT speed, cache size and allotment (shared or dedicated between cores etc). I would recommend this page: http://www.cpubenchmark.net/cpu_list.phpas a reasonably good source of estimates for comparing CPUs. Be careful though: if you must make an important comparison (eg when buying things) then click the link of each CPU listed and check that the score is a good average of several submitted scores. CPUs with only a handful - or worse only one - submitted score can have huge score variances (20%+) and mislead you. |

whats wrong with 7970 cards? they don't work well with Litecoin-mining and vanity generating also doesn't work .. I have a damn expensive card and now my fu*king i7-3770k cpu is faster than my 7970 in vanity generating  I want to use Win7 x64 + AMD 7970 + Catalyst 13.8 + oclvanitygen !!!!but I always get this stupid gpuhash-cpuhash-found-delta-ERROR Whose fault is that? AMD ? please fix this !!!!!!!!Why do you want v13.8 why can you not downgrade to 12.8? because this is my gaming-pc .. I need that driver for Battlefield 3 Well then you have a problem. Keep in mind that vanitygen was made by enthusiasts for the bitcoin community and is not a paid-for program or product, so you should not expect an easy to use push-bhutan-get-results kind of program. Even though it runs on the command line the software is actually very impressive and well designed, once you get past the learning curve. Does BF3 really need 13.8 ? 12.8 is 'old' but probably not too much older than the game. I'd be surprised if it doesn't play or if there is a huge performance hit. I have been playing bioshock infinite and a few others on 12.8 no problems.. I might suggest you consider creating a dual-booting system or install a second OS on another storage device / partition so that you can boot to it and run vanity gen. It is probably possible to run oclvanitygen on a virtual machine however unless you are extremely familiar with enterprise-level VMware implementations or have an IT degree then you will probably struggle to get that working. Seriously, installing an OS to a spare IDE / SATA hard drive is a much faster option for 99.99% of people in this specific situation... yes, I think I will install a second OS but what if this problem occurs also with AMD HD9970 ? this is unacceptable.. Right, well, vanitygen was made and supplied to you for free. Why do you think its unacceptable when you didn't even pay anything for it? Are you saying that AMD cards and drivers should be made to run vanitygen? What a joke. AMD cards are designed to appeal to and function for gamers, not people with an interest in cryptocoin software, we are an extreme minority to them, barely worthy of their acknowledgement. |

Months ago I paid 1 BTC each for 2 miners and 1 BTC in shipping to my country (I live in a technological wasteland called Australia), my miners are so far from ROI I can't express it in words.
Don't worry, bcp19 says BTC will go to $1000 and you will get "ROI". Actually, worry. A lot.  Yeah, to be clear I did not buy them with any expectation of making ROI or 'lots of easy money' (like a lot of newbs seem to... geez). I got them because they are cute and amusing, and replace my existing graphics card setup* (300 watts for a HD5970 or 5 watts for two AM USB's?!). I considered modding them as per the overclocking thread but instead I ended up just sticking the cleaned up PCB onto a huge copper heatsink, which keeps em very cool but offers no other benefit. *I was mining terracoin (SHA-256) at the time, so it seemed like a good idea. Now, not so much  |

I am not saying that the site is currently safe or not, but just something to keep in mind...
... a lot of programs that are found in the cryptocoin world are flagged by AV companies because the software (code) finds its way into (usually existing - 'plugged in') botnet software. When the victims report the infection or the box is investigated by the AV companies they just flag all the code as malicious and so it can result in false positives.
FWIW I am happy using primecoin HP releases and I have not come across any security concerns thus far.
You should all be taking basic steps to keep your coins safe anyway, like sending the majority of them to a wallet address you know is secured. Software wallet client(s) storing coins should be on boxes or at least VM's that you know are secure to a high degree...
