Where/how can we check the network hashrate ? I can't access to the block explorer.
With a normal GTX 980, I can mine at about 650mh/s : I know there are some private miners with a R9 280X mining at 800mh/s, but I can't believe hashrate is so high than you need 300GH/s which correspond to a good gpu farm (375 280x) to mine a block per week.
 

With the last version you can specify -p1 : the opencl platform is usually 0 but in my case it was 1 : I had the same error than you, and now it works.

Recently, many "last years good enough altcoin" such as mint, blk, vtc ... have been pumped without any visible reason.
Flt turn could come soon.

With only 1.5 year of experience in crypto, I no longer believe fair distribution of coins exists for real.
On the other hand, there are some less unfair than others.
Sia is not too bad in this area to my opinion (and I still can't mine with my nvidia setup on windows due to opencl platform id bug; I have managed to mine 1 block with my cpu).

Hello,

I have the error message
Initializing...failed to get Device IDs: -1

I have two nvidia card and i believe the error is due to this :
http://stackoverflow.com/questions/24200539/cant-get-my-graphics-card-device-in-opencl

The code in this miner is :
// Get Platform/Device Information
   ret = clGetPlatformIDs(1, &platform_id, &ret_num_platforms);
   if (ret != CL_SUCCESS) { printf("failed to get platform IDs: %d\n", ret); exit(1); }
   ret = clGetDeviceIDs(platform_id, CL_DEVICE_TYPE_GPU, 1, &device_id, &ret_num_devices);
   if (ret != CL_SUCCESS) { printf("failed to get Device IDs: %d\n", ret); exit(1); }

If I read correctly, this means the opencl platform is supposed to be 1, but it can be another number.
according to the :
for(int i=0; i<num_of_platforms; i++)
    if(clGetDeviceIDs(&platform_id, CL_DEVICE_TYPE_GPU, 1, &device_id, &num_of_devices) == CL_SUCCESS){
      
I am on windows now and compiling the miner seems rather complicated.
So if the personne in charge of this miner can try to correct this, I will be grateful...

80°C for a GTX980 is a normal operating temperature. I have a similar setup (two GTX 980 evga) and with quark algo and a reasonable overclock ( +100 but they are already oc : so I ran them at about 1500mhz @gpu) they are between 77-80.

Those mining with amd card are used to go higher!!!

probably memory frequency @1500 is too high for your card. Try 1250.

By the way, your psu is somewhat a bit weak for combining gpu mining and cpu mining 24H/24. It would be better to have a little bit more room.
With your psu, you can use at ease a 750 ti, a GTX 960 with mining both on cpu and gpu, but I would not mine with you config with a GTX 970 and cpu (it is OK for gaming or casual mining but a bit risky for mining 24/24 for a long period)

Gpu mining xmr is not very profitable.
The best gpu miner is Claymore for AMD : about 800h/s for a R9 290X (Hynix memory).
There is a private nvidia miner for maxwell nvidia cards (sp_ ccminer but not the public one) : but a GTX 980 has less hashrate with this miner than Claymore and a R9 280X...
 

Price is going up & down for every crypto coin with periodic highs & lows. Frequently traders pump the coin just before a new feature is released and dump on the release.

 With most coins, they reach a maximum they never recover again and gradually their lows & high are lower. But for quality coins - I believe geocoin is one of them - they can reach higher lows & highs  with dev & marketing progress...

I agree with the developper fee.
This is more fair than a fixed amount for small miners ...
You can made it switchable in the source code and force it in the binary releases (I am using the binary releases and I will be happy to contribute for 2% for your work.)

I feel the same!

I seems our vanillacoin are lost. I have bought some there before the warnings and the c-cex owner just seems to have definitely lost the coins  :

Hello,
What's happened to vanillacoin?
I had 1000 vanillacoin bought on your trading platform, I log in today and vanillacoin has disapeared ? How can I recover my coins?

Hello! Apologies for being late with this answer.

VNL wallet is beta software with lot's of issues inside and unfinished functions supplied by dev without any warany and support. We had lot's of problems with VNL wallet and spent many hours to resolve it. The last problem when wallet refused to send coins having enough balance in it (returning "connection input failed" message) could not be solved without dev help. Instead of collaboration JohnConnor refused to help to fix his software and posted this: https://talk.vanillacoin.net/topic/130/c-cex-de-list-request/4
So we removed wallet from exchange without any chance to fix wallet and send VNL balances to users. According to our rules https://c-cex.com/?id=terms this is exactly the case when we had to remove wallet without any compensation. HoneyBadger honestly offered us to help fixing this problem and we already negotiating our terms of collaboration with him. We give no guarantee but it is possible he can solve a problem with wallet and send us sendable coins so we can compensate user balances.

Thanks!

Hello,
What's up with the vanillacoin wallet ? Did you come to an agreement with HoneyBadger for an help?

Yes, but he was unable to help. It's broken.

Thanks. Very interested as you know.

ccminer was profitable with whirlpoolx, but smelter released a miner with >500mh/s for 1 280X (https://bitcointalk.org/index.php?topic=977245.900). Now this an amd only coin. A GTX 980 can do almost 300mh/s which used to be good, few weeks ago.

If you can do something like 600mh/s for a GTX 980, it will be profitable again.

Theses developpers have delivered a lot for free : but almost no donations from people using their soft. I can understand they tried to make some profit selling  private miners.

Well I hope you won't release such an amd miner qubit optimized : qubit is one the most profitable algo with maxwell nvidia : this will end as soon as an optimized amd miner is out.

Well they are coders : they have tweaked theirs miners which are more efficient than public ones, so they can ROI. But the golden age of gpu mining is probably over.
With some luck and wisdom, you can still ROI : I have mined vanillacoin as soon as gpu miners for nividia was released and I made some nice profits ( I didn't sold my vanillacoin, since I believe It can increase a lot again). I have made some little profits with geocoin too. But I loose with spreadcoin ( not selling at the right time).

To sum up, you can ROI but this is not easy. Better to buy gpu at discount or usaged.
Above all, it should be fun for you otherwise don't bother.

+1 : I am a small miner : I paid 0.1 btc for the optimized spreadcoin ccminer, but with two cards only, there is no way to recover the cost for cryptonight. I paid once because I am using the work of sp_ (and others) for others algo too in the open source ccminer.
The percentage thing like Claymore is far better for small miner. For the dev, I think it could be more profitable if the coin is good and keep value (xmr and vanillacoin should !).

Come on : for every crypto algo, probably there have been private miners : http://da-data.blogspot.fr/2014/08/minting-money-with-monero-and-cpu.html.
I have heard there were private miners for bitcoin too during the cpu and gpu mining area.
There have been for X11, groestl, ....
The most optimized here are probably about twice more performant. And the dev seems to keep for themselves (the worst would be to sell it to big private pools). With the very low amount of donations for dev, I find legit they keep for themselves for few weeks their super optimized code.
I am mining with the nvidia public miner and I find it profitable and I am happy.
