[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[th00ber]

I would love to try that but I am running on linux (ubuntu) and so can't easily overclock as far as I know.

Unless people know otherwise?

2 x 750 (non ti) give me 4.1-4.2 on X11. Overclocked (see my other post).

planning to replace my 40 280x with 66 Ti's , will save 1/2 of power costs.

With the lastest driver, it's possible
I have share the info in this thread : https://bitcointalk.org/index.php?topic=167229.msg7718377#msg7718377
YOu can also asking info on the KopiemTu (Linux nvidia mining distro) (link in the previous message)

cudamining.cc is going to go offline again in a second to yet again change everything on the website
it will be changed back don't worry, will post when it has

EDIT:

ok you can all have the website back now i guess 
Seems like most of the new system is working, i just need to edit some back end stuff still

280 h/s is the maximum for xmr?

Pretty much the highest I can get is 285 using -l 8x60 but I applied the regfix included in the last nvminer package, before that I would get BSOD trying to use those setting.

I don't see much of a difference with ccminer. I am still getting 6.8./6.9 Mhash.

Here is my config: nvminer.exe -d 0,1 -a dmd-gr -o stratum+tcp://dmdpool.digsys.bg:3333 -u user -p pass

Any additional flag that you are using to get 7.8? Or perhaps are you overclocking the card?

I'm in my car right now.   When i get home I'll lookup what I used to test hash with.   I know it wasn't the same pool you used.

I also used stock clock speeds but the 750ti is a higher end Gigabyte OCed card.
I will post clock speeds also.

isn't it illegal to surf on the internet in a car ?

I wasn't "surfing", just typing.  Ironic, however is that I was coming home from a court appearance (don't ask). 3rd appearance and postponed again.

OK as promised.  I'm rerunning another test.

Using pool: stratum+tcp://dmd.minep.it:3367
I get hash rate of 7891 hash

Using nvidia inspector I get the following:
Current Clock: 1333
Memory: 2700
Driver 340.43

So there you go.  Almost 7.9 Kh.  Easily over 8K with additional OC.

[SRBOOTH]

Slightly off topic......wondering if any of you magicians interested in a bounty for DCRYPT GPU miner.....what do you you tink the worth/merit of doing so is??? And I would love to hear some commentary on the algos viability in general.....GO NVIDIA!!! lol   Thanks

Might be my drivers. I used the latest official release 337.88

I guess I would have to install the beta drivers 340.43

Note aside, would it be useful to add a "Drivers" column to the configuration page of http://cudamining.cc/url/configurations ?

[tc61]

In the latest version of NVminer, with all the combined algos, when I am mining XMR is it suppose to slow the machine down to a crawl?

I think so but tsiv releave a version about a week ago that improve this "side effect".

Check the readme file about it.

I would love to get this version for Linux OS !

I've update to the Beta drivers 340.88 and the hash increased slightly. Now getting 7.1 Mh or so but still not the 7.8/7.9 Mh you are getting. I also tried with minep.it pool but as I was expecting it didn't change anything.

Any more ideas?

It has this facility also, it is just not enabled by default. Add the argument --bfactor=6 to your starting line. This is then the same as Windows default behaviour. You may lose a little hash, but it also drops power usage.

I have not followed the whole conversation, but I am wondering if one of you is running on risers and the other not?

That's an interesting theory. I read somewhere that indeed it could affect the hash rate http://cryptomining-blog.com/1276-first-impressions-from-a-6-card-mining-rig-using-geforce-gtx-750-ti-gpus/

I, on my side am using risers. Powered for that matter. The difference it rather significant: ~800/900 Kh

I am also using ASUS, not Gigabyte. Perhaps that could also be the reason.

Can anyone send me a link to the latest NVminer sourcecode. (merged)

Seems like the funnel shift is missing in some of the 11 algorithms: (With a ROL compute 5.0 + devices will get a boost)


From Github (ccminer 1.2):

cuda_x11_luffa512.cu:

   define TWEAK(a0,a1,a2,a3,j)\
    a0 = (a0<<(j))|(a0>>(32-j));\
    a1 = (a1<<(j))|(a1>>(32-j));\
    a2 = (a2<<(j))|(a2>>(32-j));\
    a3 = (a3<<(j))|(a3>>(32-j));
   
#define MIXWORD(a0,a4)\
    a4 ^= a0;\
    a0  = (a0<<2) | (a0>>(30));\
    a0 ^= a4;\
    a4  = (a4<<14) | (a4>>(18));\
    a4 ^= a0;\
    a0  = (a0<<10) | (a0>>(22));\
    a0 ^= a4;\
    a4  = (a4<<1) | (a4>>(31));   

cuda_x11_cubehash512.cu:
   
#define ROTATEUPWARDS7(a) (((a) << 7) | ((a) >> 25))
#define ROTATEUPWARDS11(a) (((a) << 11) | ((a) >> 21))

etc..

By rewriting these macros shift+shift+or cuda instructions can be replaced with a single rol (3 times faster)  (Compute maxwell / 5.0+)
