Until stratum works for windows miners we have opened another longpoll port on 4205 for gpu miners.

It has a higher difficulty for better pps and less stales.
Some miners stop work after 5 minutes on 4205 port, on 4200 this is not observed.

You are right! we thought it was just us, very weird, we dropped the difficulty a little bit on 4205 and seems to have cured the work stopping.

I got 3x290 and it seems work fine but than after some time the speed starts decreasing in 400 times. It's solo mining.





The Miner currently uses the cpu for sieving, and is very memory hungry,
maybe you run out of memory and parts of the program where moved onto the disk (pagefile).

The memory consumption is so high, because a very lage sieve is used, with many primes,
and also a queue is used to keep the cpu busy while the gpu is processing the fermat tests.

You can alter a few parameters to reduce the memory load:

Code:
 -s  --sieve-size        the prime sieve size

  -w  --work-items        gpu work items (default 2048)

  -a  --max-primes        maximum sieve primes (for use with gpu)

  -z  --queue-size        the gpu waiting queue size (memory intensive)

The Sieve dynamically adjusts the sieve primes,
so that it opimaly generaets a new set of prime candidates while the gpu is testing a previous set.
The queue must have a minimum size of 2.

I got 16gb memory and 16384 Mb swap and i7 4770K. Can you tell me what exactly i have to use for -s -w -a -z

Btw. Mine with pool has permanent hashrate.

Err, maybe spoke too soon, just had one miner stop mining again, just took a little longer.

Yes, I have the same, stop after 15 minutes.

Looks like your miner stopped to work, there are not accepted shares.
Do you use port 4205?

It's solo mining.

P\S to devs, i guess -z 10 solve the problem.

Actually I think 10 is the default,

We have been messing with the -z --queue-size locally with the previous port 4205 higher difficulty.

Currently...
-z 10 stops mining in about 5 minutes,
-z 4 ran for 45 minutes before we stopped it to try some other numbers.
-z 6 stopped in about 5 minutes

back to testing -z 4
15 minutes and counting...

I'll admit that I am not always the brightest and this has been asked a ton.

I created 2 different folders one 280x (device 0) and one 270x (device 1). I have in 280x folder --use-gpu 0. I have in 270x folder --use-gpu 1.

The 280x runs fine. I start the bat in 270x (gpu 1) and the bat runs gpu 0, the 280x.

Can someone enlighten me please.

-d 0 and -d 1 and --use-gpu without any numbers

Awesome man. I really appreciate that.

Got them up and running.

Can someone help me i get this eror http://postimg.org/image/i3evcadmn/

Thx in advance
delete stratum option and change port

it's working thx and how can in use all my 5 cards because it's working just Gpu[0]

Just in case you have not got them going, the answer was right in the quote.

Use an instance for each card.

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks Wink

-z 10 was about 30 minutes and than stopped.

-z 4 workin about 1.5 hours (continue mining) and 2 blocks were found in solo mode.

Man the GPU miner have really made it impossible to CPU mine this coin...

Oh well I guess i'll move on to the next interesting coin

I didnt. GPU is still buggy it seems or people dont know how to configure it. I am still getting a few blocks per day. Once network hashrate gets like 25% more then i will consider stopping too.

What bothers me as i have told before is that i would prefer a more aggresive block reward halving instead of the 2 years one in order sto stimulate more speculation.

And at least some basic marketing, not about gapcoin being the future of the cryptos but about proposing people to try it and be part of some record breaking which generally help crypto exposure...

Any ideas ?

I was triyng setting my AMD Sapphire 280X rig to it yestarday. I was able setting mining with the rig stable only with 2 cards. Obviously the GPU miner requires more powerful CPU than celeron , because of this I considered not to use the rig for GAP...

I didn't stop, my rate of finding blocks hasn't changed in the last 24hrs and I am still profitable (even with the price drop).

I would be very interested in how many coins a solo GPU miner is finding per day; pps numbers are difficult to use when a non-standard sieve is being used.

Regards,
