[ANN] New Primecoin Pool + GPU Miner

[madMAx510510]

--------------------------------------------------------------------------------------------------------
UPDATE: Pool is closed.
--------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------
NEWS: I've decided to go open source: https://bitcointalk.org/index.php?topic=602292.0
--------------------------------------------------------------------------------------------------------

After a few days of testing my new Primecoin pool is now open to the public:
http://54.187.143.168/

I don't have a domain name yet, sorry. The pool works with my new GPU miner which you can download here:

EDIT: this is new version rc1 for i5 i7 fix!
32bit Windows: https://mega.co.nz/#!QBpnDSAR!5_AVpyO2ow1Y5NAAryZdeRcUtOH0rZTmalMfWMoeB_8

EDIT: same fix for linux will follow shortly.
64bit Linux: https://mega.co.nz/#!NEomzA4B!DqKHLTaA6jNPVaRi7BOIERKHbDkicTJDW80vKTWhV4o

To start mining:
1.) Download miner and unpack.
2.) Put your payout address in config.txt
3.) Now you can start the miner
4.) After you find your first share you can view your account and workers on the website

Pool System:
- Similar to beeeeer.org
- The automatic payout threshold is 11 XPM
- Exception: Your very first payout will be requested once you hit 1 XPM to confirm your address
- There is no manual payout (yet)
- Payouts will be executed after ~2 days when the coins are mature
- The minimum share is 8-chain
- Each share has a value that is recomputed every 30min based on the last 24h
- The poolfee is 10%

Known Performance:

3.3 CPD on 7950 @ 1000/1250
4.1 CPD on 7970/280X @ 1100/1250

Yes those numbers are real . They are accurate to +-0.5% when averaged over a long time.
Also, you can see the memory clock does not need to be very high.

Some things you might want to know:
- The Linux version is untested.
- The miner works with Catalyst 14.4, older versions might not work as good or not even at all (EDIT: 14.3 should be ok too)
- The default settings are optimized for 79XX and 280X
- For 290/290X you can try sieveprimorial = 12

The website is still very basic, but get's the job done. I'm still working on it.
The site will automatically reload every minute, so don't use F5 please.

Happy mining!

Cool!! Definitely taking a look!

sas that need 14.4 driver - its very bugged

Catalyst 14.3 should be ok too.

Can anyone vouch for this pool/miner?

I don't have the means to test it atm.

[kaleruka]

i start to test with some of my rigs...wil report later

why so high latency at pool?

[madMAx510510]

why so high latency at pool?

It's the average of all connected workers. But ~200ms is still very low, keep in mind this is 2x network ping latency + server cpu time needed to create all work.
On other pools this latency is in the order of multiple seconds and that's why they have so many stale/invalid shares.

got 1 xmp on balance allready & didnt reciew it yet(

[mainman1009]

What are you valuing 11 and 12 chains? Also is there a block winning reward?

[madMAx510510]

got 1 xmp on balance allready & didnt reciew it yet(

It takes ~2days for the coins to mature. I don't have the funds to create a buffer to be able to pay immediately.
Although in the future this might be possible, once the hashrate has stabilized and is not increasing.

What are you valuing 11 and 12 chains? Also is there a block winning reward?

Anything above 10 is valued as 10, because these chains are so rare that you don't want to depend on them. Therefore 10 chains have higher value of course.
And there is no block reward for the same reasons.

Does anyone have a link to 14.3 drivers for windows 8.1? At AMDs page I only find 14.4 now...

Code:

error: ProbablePrimeChainTestFast 0/4

[kaleruka]

in next version of miner please add GPU fan control

[madMAx510510]

Code:

error: ProbablePrimeChainTestFast 0/4

It happens when you OC too much. Try lowering memory clock first, this helps a lot in my experience. Even stock memory clock isn't stable on some cards.
EDIT: Once a GPU has crashed you need to reboot for it to work again without errors.

in next version of miner please add GPU fan control

Can be done. Do you mean a static setting of how much % or an automatic control that tries to hold a certain temperature?

[kaleruka]

60-80%

No ammount of overclock change has seemed to get it to stop crashing on startup i had the same error and now that i have lowered the overclock i don't even seem to get that error but its just straight up crashing as soon as it gets work from the server.

 I'm testing it on a rig of 4 sapphires 290x, windows 8, i7 3820 and 14.3 drivers however on my other rig using windows 7 it all seems to work nice and if you actually pay out then this is one hot smoking miner but would love a fix for windows 8 rig if possible brah

gj man, i see a little problem, i connected 6 rigs and ur pool shows me only 2 of them - can u check is everythink allright?

Hi,

Thank you, finally one for Linux!! I was lazy to try out other's XPM miners as all of my rigs are Linux.
Just downloaded Linux version and testing with a 5xR270. Seems working but all the set core and powertune failed.
Does it even support R270? I will test with 7950/7970 later.
The followings are the corresponding error messages.

Try having a look at the readout in the console i have a feeling you will see your cards saying crashed
