CUDA Optimalized BTC miner for NVIDIA cards

[icedev576]

I`ve started to optimalize the rpc-miner CUDA version. Currently it runs on Linux (Ubuntu 12.04), and tested on 2 different cards:
Asus GTX-590: 260 MH/s (no OC)
Asus GTX-690: 230 MH/s (no OC)
It is about 15-30% faster then the original.
I started this topic to discuss is it worth it to continue this project or no one interested in...

I am intersted in your current hash rates on newer nvidia cards also.

I accept donations for this project in the following BTC address: 1GgnBSzLq6DioYS4haPSx6gZCeL9KMUYFW.

It will be opensource.

Hi!

I have an overclocked 680 and have only 135 Mhash/s. I would love to see if your modification helps a bit. By the way I am using on older Ubuntu. When will it be available?

This is interesting. I am reading the post, maybe I can mix the solutions together.

[klintay]

yeah i would be interest too in this!

[smoothie]

Hopefully this hasn't already been optimized. But if so, good job.

[icedev576]

My code is a mess now, so it isn`t ready for a public release, but because gaborjakab uses almost the same hardware, and OS like me, I can send a binary from the current stage just for the test. So if you like please send a private message.

[LighningChun]

i have a gtx card, looking forward for this! 

[icedev576]

Well, I read the whole "NVIDIA Kepler (K20) from 134MHash/s to 330MHash/s with CUDA" topic. As far I know psychocoder has optimalized the cuda code for the GK110 architecture (sm_35 in cuda). There was only 2 card supporting this: Tesla K20, Geforce Titan, but from yesterday you can buy the Geforce 780! It is the same arch, a little cheaper and more consumer. If I had enough donations, I will buy one.

My solution is speeding up the older generations: Fermi and Kepler(sm_20, sm_30), that means geforce 4xx to 6xx. So I hope I can merge them together.

I sent a binary to gaborjakab, others please wait and keep me posted.

Thanks man, I have tried it, now it goes with about 150 MHash/s, about 10% faster then before. It is not a miracle, but it is something.

I used a gtx 660 (non Ti) i couldnt get it higher then 73 mhash/s

[icedev576]

Thomassie12 are you still mining or you give up? What kind of miner do you use or used?

[kenshin23]

I'm currently using a EVGA GTX 670 with cgminer and I get 91-95 MH/s. Seems low, but I don't have any sort of optimizations for it just yet. So I'm very interested to see what you can achieve with this.

[icedev576]

HI Kenshin23!

Can you give me some information: what OS you use is it 64bit win or linux(distro?)? And the most important are you using rpcminer or something else?

[Cyberclones]

I started by running a EVGA GTX 550 Ti 1 GB was getting about 45Mhash/s without a overclock on it but I no longer run it

[icedev576]

I`ve managed to merge the source. Tomorrow I will upload the source code to github. I am also thinking to create an cuda mining survival guide to add some help for nvidia card owners.

[kenshin23]

HI Kenshin23!

Can you give me some information: what OS you use is it 64bit win or linux(distro?)? And the most important are you using rpcminer or something else?

Hi, sure! Win 7 64 bit and currently using cgminer 3.1.1 as-is, but willing to switch to another miner if it means it'll be more efficient.

The CUDA mining survival guide sounds great; looking forward to it.

[OnLashoc]

I'm in same boat you are ^^

[xh4]

Looking forward to using all my old graphics cards for something useful...

[gaborjakab]

Any news from here? I am still waiting the sourcecode.
