I successfully compiled primecoind in OS X 10.8.4. I get 0-4 primespersec with an i7 1.8 GHz in Macbook Air mid-2011. Is it worth bothering at this rate?

Give it some time, I believe you'll probably average out at something a little higher than that. How long have you had it running? Let it run a few days you could get a few blocks while the difficulty is relatively low.

Okay, just about two hours. It was up at 8, down to 5, and currently 6. Thanks!

Edit: Up to 12 and down to 10.

Not a problem, good luck. I'm running mine at setgenerate true (x) where x is one less core than the CPU max.

So for my 6 core AMD I run setgenerate true 5

It seems to be giving me higher consistent primespersec, though I am gpu mining on that rig as well and if I don't exclude one core my cgminer performance hits the gutter.

Ok, I just started this up and did exactly what you said. I have never mined anything before, but figured I'd give it a shot. I have an Alienware M17X R3 laptop. My primespersec is so far going between 18 and 88. Does this sound right?

3 questions:
- What does primespersec mean? Does this number judge how fast you will mine coins?
- When I mine coins like this, do they just show up where it says balance?
- If CPU usage is at 100% is there any danger in just leaving my computer on all the time, like overheating?

Something seems to be wrong here:

PC1 (Workstation): 1x Xeon Quadcore 3 Ghz, Win 7 -> 74-106 PPS
PC2 (Server): 2x Xeon Quadcore 2,4 Ghz, Ubuntu -> 1-15 PPS
PC3 (Server): 2x Xeon Quadcore 2,4 Ghz, Ubuntu -> 1-15 PPS
PC4:(Notebook) 1x i5 Mobile Dualcore 2,5 Ghz, Win 7 -> 3-14 PPS

While I can imagine that PC4 is simply that slow, PC2&3 should be much faster then PC1. CPU is at 100% and Primecoin the only thing running.

Does anyone have an idea what´s wrong here?

Basically, yes. You have to have luck to find a block. But your chances are higher when this value is higher.

Yes

You should ofcourse check your CPU temp. But normally this shouldn't be a problem. If your cooler is adequate, everything is fine.

Update:

Set up PC5 (Server) with 2x Xeon X5355 2,67Ghz (Quadcore) and Win 2k8R2. Same problem here only 1-40 PPS. Way to low for 8 physical (16 virtual) cores. Wondering what could be the problem?

My top rate yet is 23 primespersec, down at 2 now.

I have 60 XPM, so it's definitely worth mining with my Air. A friend with Sandy Bridge i5 3.3 GHz (desktop) has got 80 XPM in only a few hours less time.

Does the CPU keep mining when I go to bed and the computer falls into Sleep mode?

How do I keep it mining if so?

Thanks

When I got to check my computer today it said that the Wallet was behind so I'm assuming it stopped mining when it went into Sleep mode.

Can anyone confirm if this is correct and that I must set the computer never to sleep?

Sentinelrv · « **Reply #37 on:** July 08, 2013, 05:13:20 pm »

Well, it's been 10 hours and I have 19.84 XPM. Is this normal for my speed? It's been around 80-90 pps.

When the computer sleeps it goes to a low power state and program activity stops. If you want it to continue mining, you need to set it to not sleep.

So I mined some primecoin. My first ever of any kind! pretty exciting for me anyway.

Question:

It says they are immature and unconfirmed.

Do I need to do anything for these to be confirmed?

Will each "find" have a different transaction address and if the transaction
address where discovered by someone else, does that mean all of these
19.73 XPM would be vunerable to theft?

parachatt · « **Reply #40 on:** July 08, 2013, 09:14:21 pm »

I'm also trying to mine some XMP
My "hashrate" is around 200 pps
I got 19.64 XMP labelled as immature which have completely disappeared off my wallet before to be confirmed
Can someboby be so kind to explain me this issue

?
Thank in advance

Mine are still showing as immature. Not showing as unconfirmed or in balance yet.

Could anyone comment?

Mined blocks take something like 3000 confirmations for primecoin i believe.

So just wait it out and you will get your coins in your wallet soon enough

One thing u can do is see how many confirmations you have on each block u mined... go to the transactions page and hover the mouse over the block stopclock on the left hand side..... or go to the debug window and type "listtransactions" and you will see the number of confirms there.

Hi Fuzzy Thanks for the responding.

Do you use the encryption method in the wallet listed under Settings or is there a better alternative you use?

Is it okay to back up and/or encrypt while you are waiting on coins to mature?

Regards,

Adrian

My plan to mine with a ton of cores fizzled today. Got one server loaded to try it with 48 cores. It was suggested that the CPU cache was not enough for all the work it was trying to do.

I tried several different methods, played with the Windows settings for L2 cache in the registry and after a two hours I had a whopping 2 primespersec on 48 cores.

Giveaway will have to wait a few weeks
