Primecoin GPU miner: 9.1 CPD on a 280x / pool / 2% dev.fee

[csa1234]

i have to move to Claymore miner since its the only miner that accept catalyst 13.12 and those drivers are the only one who will work on 6 x GPU at same board.

Well, I'm not sure it's more profitable to mine on 6 280x's with Claymore's than on 5 cards with our miner.

PrimeGPU i sent you an email with new key request for upgrading to 5 x GPU

Higher difficulty.....
My blocks are coming much slower.  The last couple days I have only gotten 1 per day, where I was getting 4 or more per day. 

I have a mixed gpu rig that just stops when running the last revision of the miner, even after lowering all cards to stock clocks.  I just went back to the previous revision of the miner and it is fine.  Is this due to increased usage % or could it be something else?

Most likely.
Could you tell if it mines for at least an hour or just stops right away?
Does the other rig have the same problem with the latest version?

We'll probably make this optimization optional.

Been running the free version for a couple of days now but it seems very unstable. Fresh win 8.1 installation, 14.4 drivers. Sometimes it crashes the miner, sometimes I see that the computer just have restarted. (and I can only run 5 of my 6 cards, error code 43).

It is unstable or should I do something to get it stable?

i see the website is gone 502 bad gateway

It's quite stable in our rigs. Have you tried running it on lower clocks?

How's the progress with the pool?

We hope to have it in the next version.

It seems to go for a while before stopping.It would always stop after I quit watching it.

Also,  My house was getting too hot, so I have moved my rigs to a remote location. so I haven't messed with it too much.  Stability was more important.

I guess its about time in view of crazy difficulty ahead.. is that going to be your own pool? no more ypool please..

How's the progress with the pool?

We hope to have it in the next version.

I am running my 280xs in 1030/1500 mhz. Should be fine right?

you will be fine. In fact i use it with 1150/1500 (MSI R9 280x Gaming OC + Sapphire R9 280x Toxic)

From the other miner's thread:

My 280X give 189K 4ch/h & 2.2CPD (48h), but how about yours 4ch/h?

sometime give mi invalid shares

7% invalid shares is the same as having 7% stale/orphan blocks.

A pool is much needed at this point, since the difficulty is high. I notice I get a lot of 10.7 to 10.2 out of the 10-ch I find, no blocks for 96 hours of mining. So, I had to switch to the other miner for pool mining.

Just think of it this way.


with the difficulty at 10.88 you basically have a 12% chance that a 10 chain will be a block and that will only shrink further.

I would say solo mining Primecoin is (currently) dead. Just waiting for a block before I move over to ypool.

[kev7112001]

not dead at all u might not hit a block in 48hrs but it doesnt mean that u wont hit 1 after that or 2 etc just the way soloming is it will average out the same

when soloming u should mine for at least a week to compare with pool and with pool u have down time and pool fees
