Did make me think Sunnyking maybe in southern hemisphere as both PPC and XPM were launched during the summer… either that or he has kids and that’s when the wife takes them off on holiday and he is given free reign of the house and his time and hence launches his new coins 
Got two blocks over the weekend @ nearly 40k pps. 
But it´s still a better quote the mining at ypool atm. But when the diff is going up more and more, someday I have to switch over.
Which CPU will you advice me to buy for mining XPM on a s1155 machine?
I want to upgrade anyways, so why not get some XPM. I can get good prices on:
I3-3XXX
I5-3XXX
I7-3770
Which one is the best - performance vs. price?

That’s a really hard question. We don’t even know why certain machines appear more effective than others. Some people claim that certain AMD processors are even faster. Even these anecdotal evidences are real, it’s probably due to some features in the current miner software unintentionally hitting sweet spot of these CPU/architecture. If the miner software changes the feature, e.g. a replacement of certain algorithm, then the advantage could disappear.
You could get one of each and run the latest miner and see which gets more 5-chains/h, or performs better on testnet. But neither is a sure indicator of mining speed.
This may help you with your decision:
http://www.tomshardware.com/charts/cpu-charts-2012/benchmarks,140.html
It’s the CPU chart from Tom’s Hardware, and it includes all the processors you have mentioned as well as a varity of benchmarks.
Finding Primecoin blocks has more to do with luck than processing speed. I’ve mined 24/7 for a few weeks now with 3 different processors, and the number of blocks I’ve found on each system has no relation to their speed. Unfortunately, the chart I’ve linked to doesn’t have a “CPU Luckyness” benchmark!
I’m assuming that Primecoin mining is not the only thing you are going to use the computer for, so I’d recommend looking at the benchmarks for whatever it’s other uses will be.
Wow. I had about 60K pps split among several machines and found 17 blocks. That’s just bad luck, mate.
fwiw, I have found that I have much better luck on machines where I compiled Openssl (CentOS) than ones where I did not (Ubuntu)
This is the key word, but at the end if you have enough power to cut down variance luck should not matter. :
The CPUs will be put on my scrypt miners around 20 machines with s1155, so they will be used only for Primecoin mining.
Now I Have Celerons G550 G1610 etc. I can return them, pay some extra and get something more powerful so I guess I will go for the 3k series
On my little Intel 3 GHz dual core box, I see this:
"primespersec" : 142,
"chainsperday" : 0.02146100,It’s been running for 3 days, and nothing. Some of these posts suggest that I might find one block within a few days. Others say that 10x my PPS rate might result in a block within a month. I have no idea who’s telling the truth. I really like the concept of XPM and would like to be spending my cycles on something useful, but I have a sinking feeling that this is already out of reach for someone not willing to dump another $1k into equipment.

Pool mine my friend… ypool.net is your friend 
My first 8 hours of mining XPM I got 2 blocks ;D
1 from my i7 3.5GHz 4 core
1 from an Amazon EC2 8 core beast
Since then 1.5 days later and nothing …
I’m thinking of going over to the pool to see if that makes much difference. Anyway, I’ve been digging through the log files and charted the difficulty level as every time I look it has gone up. Here is the chart any way:

Always with the pools. I ran it for 12 hours and didn’t get one share. Even CPU mining with litecoin will generate a share every once in a while. I dunno.

Are you using the latest version of their miner? its on 0.3.5 last i checked, and one downside I have noticed on the pool if you are not using the latest miner chances are yes you will not get a share… i have some very old cpu’s running on the pool and yes just like litecoin they will get a share every once in a while… but i had not updated from the 0.3.2 version and had a day or two without any shares or coins.

Some results finally. The stock miner from ypool didn’t seem to work, even after half a day of mining. I dug down to this post https://bitcointalk.org/index.php?topic=257623.msg2846079#msg2846079. Normally I’m pretty resistant to downloading binary blobs from random people on the internet and running them on my machine, but it’s not running as root so what could possibly go wrong?
So on my Intel Pentium D dual-core 2.80GHz box, after running for only a few hours, I see:
SPH: 2.04 - Val/h 0.8268 - 4ch/h: 268 - 5ch/h: 24 - 6ch/h: 5.09 - 7ch/h: 1.02 - PPS: 690Yay. Rather piddly, but I’ve finally gotten a result. I have a few shares in ypool and have something to show for my efforts. Yes I have to run things in wine but them’s are the breaks. I still have some doubt that a GPU miner will be all it’s cracked up to be, given the nature of the math involved.
Anyone know of a porting effort to native Linux?

I have been testing this one out myself on Ubuntu 64bit 8 core Opteron under wine and found v4 works better than v5. However, on my Win7 64 bit Desktop the v5 works better.
I would like a port to Linux also …
I got a strange block reward last night…
In the last few weeks I’ve probably found about 15 blocks, and each time the reward has been 11.xx XPM per block.
However, last night I mined 2 blocks within an hour of each other. The one mined at 4:03am rewarded 11.10 XPM, but the one at 03:14am rewarded 11.112418 XPM
Anyone else had this happen?

That will be a traansaction fee that has been added as reward to the block
Could happen when difficulty drops, too.
I’m running a number of vps machines on DigitalOcean, and I’m getting quite a number of shares on Ypool.
I have set up Fedora 64bit Desktop, with wine installed, running jhPrimeminer v7.1
I use -s 2000000 because mumu recommended a minimum of 2000000. The PPS goes down from when I was running -s 300000, but the number of shares it finds goes up. So PPS is not the true measurement on Ypool, only an indicator.
With this setup the PPS varies from 4500 to 5750. I have 30 of these running, and I’m getting around 12 XPM per day with these.
Until v7.1 came out the workers kept coming up as inactive, now they stay green, and rarely turn yellow.
I also have an old e-machine computer that I installed Ubuntu on, running v7.1 and it finds a share every 3 to 4 hours, not very exciting. 
I have found 12 blocks so far in 10 days of mining on YPool.net.
Just wanted to state an observation here.
YPool.net is mining just under 30% of the blocks found.
in the past 72 hours we’ve mined 1176 blocks. I’ve checked the block numbers and in the past 24 hours the network has been mining just under 1 block a minute. So right now, there isn’t a huge increase in prime processing as some other threads are suggesting.
Its very easy to see if that were to occur, because the block numbers would go up dramatically, indicating more than one block per minute being mined.

Is it not quite expensive to run 30 instances on DigitalOcean? 30 x $20 = $600/month?
