[XPM] [ANN] Primecoin High Performance | HP14 released!

[nhminer]

Isn't it still 10.47 or so?

The last block reward I got was 10.47. With the current difficulty of 9.76620036 (block 123751) one should get 10.47 XPM reward. But maybe I'm on a wrong chain - with all my miners...
Btw blockhash for "my" block 123751 is 103c5b2d0c5b3fd3531b662d17460e4b5832f56af74003b981c24be1d86d56b8
Is that the same for anyone else?

My last reward was 10.48 and my block 123751 hash agrees with yours

Just read in mcxnow chat that someone has a working GPU miner they coded themselves.  They claim to have earned nearly 300,000 XPM with their 25 x 7950s.  And they also claim to have sold 150,000 of that over the past few days, which would explain the dip in price recently.

Yes it's WEF.
He supposedly had a gpu miner 2 weeks after the launch of the coin. He said he has sold 150K over the past 3 weeks.
There is no proof, it's only his claims.

[crendore]

If it was true there would be no reason for him to say it, especially now.

Believing anything you read in the troll box

To be fair the mcxnow chat is far less retarded than the btc-e chat.

I have mined on a variety of AMD and Intel CPU now and in conclusion the way to 'tune' your CPU is to buy a faster one. The only way you could have 'detuned' your CPU is if you installed a 32-bit OS on a 64-bit CPU or if its reducing its own clocks because it is detecting that its temperatures have reached a thermal protection threshold. I have a laptop that will do this (i5) and it will never go its highest multiplier. It just adjusts itself to be around 80 deg C. The maximum Tcase temperature according to intel is 105 deg C though.

The reason I was asking is that several people have said they are getting .8-1.0 chains using AMD processors. The FX 8150 scores fairly well on cpubenchmark.net with a 7755:

It seems like mine is under performing.

Crendore did a great job of illustrating the spike I was talking about. HP9 with the current miners seems to have maxed itself out at around 9.75 then there was a sudden change in the slope with a relatively quick clime to 9.77. Not a big change numerically but I get the feeling it takes a lot of computing horsepower to change things that much at this difficulty. When I turned off my servers last week it barely registered on the difficulty. I was running around 90 chains/day with them.

At 10.6XPM per block and 1440 blocks a day on average, they must have mined 70% of all new XPMs since July 22, two weeks after Primecoin was released, leaving the rest to ypool. They could launch a 51% attack and  didn't ? Hard to believe.

ty for confirming that. I don't wanna get zaxed

A change of 2% over the integer 9 difficulty is barely worth mentioning. I find it hard to believe you can really consider it a significant change.

Turning your servers off is an entirely anecdotal example. Also as it is unlikely you have access to such hardware for free, I am going to assume you splurged on VPS for a few days at most. In the other thread they are discussing VPS hosting for $5-20/month for 1 chain/day being 'reasonable' so having 90 seems a bit extraordinary.

There are thousands and thousands of VPS servers running primecoin right now. Why? They take nil effort to set up. All considerations of running them are moved off site and lumped into a simple daily/weekly/monthly fee. People will take advantage of any such situation even if the profit margins are small. Then you have the casual people mining on their gaming rigs at home on i5's and i7's etc. Your servers are just some of thousands of the thousands of CPUs mining so its not surprising there was no change in difficulty.

Five weeks ago one person such as yourself may have been significant on the network, when the difficulty was <9.00, but now primecoin is well known amongst altcoin miners. The secret is out. I would think over 250 pages on this forum alone related to primecoin topics would've indicated that clearly. This coin remains highly profitable to anyone with enough good CPUs available or who can spend some time working out the best options for VPS servers. Although I was never heavily invested in mining any other types of coins, and I do have some GPU and ASIC, they remain pathetic compared to the profits seen from primecoin. I feel like primecoin is a profit void, waiting to be filled. I think it has a long way to go yet.

mcxnow trollbox GPU miner story? Seriously?  

[jjiimm_64]

They could launch a 51% attack and  didn't ? Hard to believe.

What would the incentive be to launch a 51% attack?? 

Is there something i am missing?  Is there a way to profit from such an attack more so then just mining the coin directly?

You are not missing anything, you are right - there is no reason to launch 51% attack except to destroy the coin, Satoshi Nakamoto proved it in bitcoin paper.

[crendore]

Couldn't you do double spends though?

[loucy]

You could, but you can make much more profit by mining and selling them. A successful 51% attack would destroy the coin and make it worthless.

It doesn't have to destroy the coin. A 51% attacker gets to select whose/which block gets to stay on the main chain. It has many applications. Double spending is one of them.

JUst started to mine XPM, but I have no idea how to set things up.  Downloaded the QT from first post, all synced up, but the only guides I can find seem to go through the command line instead of an exe or a bat/conf file.

Create a shortcut to the .exe or make a new shortcut, with the target field as follows:

C:\Windows\System32\cmd.exe /c start "runlow" /low C:\primecoin-0.1.2-hp9-winx64\primecoin-qt.exe -gen

Edit folder location as necessary.

This will launch the process with a low priority to allow your computer to run other things with their normal (default) priority without competing  for CPU with primecoin.

The -gen sets it to begin mining without needing to go into the clients console.

You could just as easily make this into a .bat if that's more appealing.

You can also add this shortcut/.bat to your windows startup folder to easily make it start with windows.

We are taking these for buying Gold and Silver for a week to see if the interest is there and which coins we decide to keep up permanently

Yeah, I've tried that guide, but there's no console window like cgminer to show me if I'm actually doing anything.  My CPU is pegged at 100% though
