Whats happenned? Why my account balance become too small?
Now pool make payments without 2,5-3 day delay (15 minutes maximum), check your wallet Smiley I'll add message on web site about it.

I am interested to know if it will be using CUDA or OpenCL for Nvidia? My guess is OpenCL as it is a nightmare to recode everything in CUDA and then maintain two versions, but CUDA should be quite a bit faster than OpenCL on Nvidia platform.
I'm using OpenCL with diffenent implementation for some functions.. and don't see a much speed difference between CUDA and OpenCL on same code.
NVidia Maxwell GPUs required different sieve implementation, if I create it, GTX970 will do 9-9,5CPD, GTX980 up to 11CPD, but it not easy Sad

miner generates a message - disconnect retry 30 sec
Problem solved? I see your wallet in payment log for 26 Nov.

You should be right as you are the expert. My thinking is simply based on the fact Cuda being more "native" on Nvidia platform and miners using Cuda (e.g. ccminer) seem to be much faster than OpenCL miner on those X11/13/15 algorithm.

Can it work well on 5970 GPU-s?
It is working with Claymore miner 3x 5970 only 11cpd any driver any version of Claymore miner!!

NVidia GPUs have some features accessible only from CUDA.. may be X11 and other miners uses itAssuming XPM uses bignum stuff - I'm pretty sure it does, but I've barely looked at the code - CUDA should provide a speedup, if done correctly. Might need PTX assembly, though.
PTX assembly available in OpenCL too.
https://developer.nvidia.com/opencl - see "Using Inline PTX with OpenCL" example.

Can it work well on 5970 GPU-s?
It is working with Claymore miner 3x 5970 only 11cpd any driver any version of Claymore miner!!
I have kernel for HD5xxx GPUs, but this GPU not suitable for XPM mining, too low speed compare to GCN HD7xxx & R9 2xx cards.

But in my opinion, CUDA is simply a lot easier and nicer to code with.
For me not so much difference.
But some NVidia features not accessible through OpenCL, for example http://acceleware.com/blog/keplers-shuffle-instruction

I am test running it on 7950 1150/1550 how much  cpd should I expect?


EDIT


unfortunately the card clocks fluctuate as well as usage and CPD stays at 5.5...

how can i stop usage fluctuation?

Update.

my r9 290 mines away at 14.2 CPD (1000/1300)

I solved the throttling on 7950,seems it is hitting a wattage wall.

However at 1000/1550 the card gets only 5.3 CPD is this normal for a 7950, I thought it should be over 8 CPD

You also can try use address from exchange (Cryptsy or other), it must work.

Hi, is there still plan to support Nvidia by v10?
I have unfinished miner for NVidia 750Ti / GTX970 / GTX980, but performance too low compare to AMD GPUs (~6 CPD on GTX970 and ~7.5 CPD on GTX980, it's 1/2 of R9 290X speed).
