I'm also seeing some strange fluctuations - I have one system with two 7850s getting roughly the same hashrate on the worker as a second system with only one 7850 on a worker. I feel like I'm asking something that was probably already answered, but why does the value reported on the website vary so much from what my miner says? The website says anything from 100 to 700 Khash/sec for a single 7850 when the miner on my pc says 260 Khash/sec right now.

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.

you are at the pole.

But I'm lazy... If anything I would find an exchange that trades them and put the exchange wallet address and trade them for something else...

I like trivia and don't care about coins - can I still play without putting up an address?

Thanks for the update. I know everyone here is glad to get an update for a highly anticipated project like this one. I can't wait to see the working version.

It wasn't a payment, it was a donation. The ability to test the miner is a bonus perk and not something you directly paid for. But again, lets not turn this thread back into an argument about what constitutes a donation or a payment. If we do that it just wastes everyone's time and clutters the thread with more nonsense nobody really wants to read.

The one getting 0.5 cpd is a Phenom II x4 960T (the six core with two cores locked) and the 0.7 cpd one is a Phenom II x3 740 that was unlocked to x4. They have the same cache sizes and operating frequencies but are slightly different chip designs (x4 vs x6).

Yeah, it's really hard to follow a thread like this especially when dealing with outside issues like work/school/etc.

I feel like I'm going to be lazy asking this question since it probably has been answered somewhere in the thread, but I have two similar computers mining. Both have Phenom II processors and one is running windows 7 and the other is running ubuntu 13.04. Both computers are running hp9. The one running it in windows is getting 0.7 cpd and the Ubuntu one is getting 0.5 cpd despite the fact that they have phenom IIs with the same number of cores and the same clock speed. Could this be caused by the fact that one of these is a quad core chip (the 0.7 cpd cpu) and one is one of the 6 core ones with two cores locked (the 0.5 cpd chip)? I'm just trying to figure out what I should be doing to get the one with lower performance to match the other one.

It's a bug in the primecoin client - It's been partially fixed but everyone gets it occasinally. From what I have heard systems with more cores (6+)tend to get it more often. All we can do is just restart the primecoin client to deal with it for now.

It seems to not be accurate for me - I haven't gotten any blocks since the 25th (other than an orphan on the 25th) on my desktop though so I feel it's hard to tell.  Then again my sister got three blocks on saturday with the same cpu... It seems like it's a rough average that was accurate when it was added but is slowly becoming less useful for judging how often you might get a block from my experiences.

It was a spike on Cryptsy. Take a look at the graph there - it's still at .00835 right now though.

Ah, thanks. I have a friend with some good video cards but a terrible cpu that was thinking of trying it out just to see if he could get anything with it. I just want to get an idea since I haven't gotten a block on my 3930k since the 25th. Luck tends to be that way anyway... I got one a day for three days and then an orphan - nothing else after that cpu mining. It just worked out that way...

Look at those xpm prices tonight... they went up from .006 this morning to .01 at a peak tonight - back down to .008 now....

Lets get off the topic of what constitutes a donation or a purchase for now.

On a completely unrelated note, has anyone downloaded that "alpha copy" of a miner that has been floating around online? I'm curious about what it actually is since nobody here actually said anything from personal experience as far as I could tell - it seemed like people were just looking at what antivirus programs picked it up as malware on virus total or something like that.

This is the CPU version of the Reaper miner that was mentioned earlier in the thread.

I see something similar to this on my end right now but not that bad - On my 3930k I can set genproclimit to 6 and I get 2517 pps and 1.2 cpd and with genproclimit set to 12 I get 2900 pps and 1.4 cpd. Something seems wrong with this right now. I also set genproclimit to 1 and I'm getting about 450 pps/ 0.23 cpd. If the performance scaled linearly I would be getting ~5kpps/2.7 or 2.8 cpd. Yes, I know that I should never expect anything like this but it seems like the performance scales linearly up until hyperthreading is involved and then it steeply drops off.

Edit: I just tried a few values between 6 and 12 and I'm getting at most a 100 pps increase in performance from one to another, and in some cases no significant increase whatsoever (going from 9 to 10 increased from 2784 to 2832).

I like your sense of humor. Your post made me laugh. Thanks for giving people the xpm donations - it helps people with no luck mining get started with primecoin.

People keep forgetting how the reward for mining a block is generated. With primecoin it is anything but a static reward and within the span of a day it can fluctuate from about 11.75 to 11.55 (roughly the change over the last day). Primecoin block rewards dynamically change with the difficulty - the equation for it is 999/difficulty^2 if I remember correctly, so as the difficulty goes up the reward per block plummets.

People are speculating that the price won't tank in the same way as expected since the difficulty is recalculated with every block. It also changes the reward with difficulty since the reward is 999/(difficulty)^2 or something like that. That would mean if the difficulty was 15 the reward would be something like 4.4/block instead of the 11.6 or so we are getting right now. At the same time there will be people that will dump for low prices on the exchanges just to get cash quickly which will really drive the prices down. But the way I see this right now a gpu miner would help the difficulty rise fairly quickly which would drop the block rewards and make each individual coin gain more value over time with a lower inflation rate. With that said, the inflation rate will probably temporarily rise when the gpu miner is released since the difficulty isn't able to catch up instantly, meaning there will be some excessively high inflation for a short period of time. It's honestly anybody's guess where it will go since it's a new market without a lot of support yet.
