CCminer(SP-MOD) Modded GPU kernels.

[Epsylon3]

The 650 is doing pretty bad. 727KHASH@x11. The merged simd code (compress1/compress2) into one kernal, reduced the performance by 10KHASH. (1.3%) But Cudaarch is not possible to check in host code.

In fact it is check fugue :

        int intensity = (device_sm[device_map[thr_id]] > 500) ? 22 : 19;

Thanks. Checked in a fix for 650 now.

I also managed to make x11 and x13 25KHASH faster by moving the final test into the (echo and fugue) kernal. @github.

Will prepare an exe for test. Build 9.

exe 9 can be found here:

I've made a pull request on github.

The Hashrate didn't increase after your commit, but the power consumption is down. Memory controller load is now 14-15% and power 65-100%. I have also removed /merged some kernals, so this can also be the reason. Memory load in the previous release on 980 was above 20%.

release8 had 28% load@9.3 MHASH

nice work, that give me a lot of things to check for 3.0 simd, check my latest commit...

[sp_]

The simd fix for 3.0/3.5 is nice. I only fixed x11 in my fork, so yours is bether. When comparing, you should also check the Wattage. Some changes does not improve hashrate, but they do reduce power.

[Epsylon3]

yes, i need to double check the commit, i lost 1ms, edit: ok fixed

@sp_ I'm mining at yaamp.com and release 9 doesn't seem to connect very well to the mining pool. No problems with release 8.

Edit: CCminer(release9) sends 1 share then doesn't do anything else after. However gpu is at 99% load. Same for every algo. It does work for nicehash/westhash and p2pool.

Same here. GTX 970, tried both exe files different pools (X11,13,15) it's a hit and miss.
At least I couldn't find any dependency on when it connects and when it doesn't.

+1 same thing , lots of connection interupts...

Mine on a pool without extranounce support. F.ex wafflepool. What rates are you getting on benchmark mode?

[Epsylon3]

i made a fix for yaamp today... but todays disconnections are not related to the code. yaamp doesnt use extranonce, only nicehash and westhash

[jjjordan]

benchmark (970) is:
X11 - 7.3
X13 - 5.4
X15 - 4.7

[sp_]

I have tested the build 9 on wafflepool and it reports nice rates with little disconnect.

Could you try the binary from the blog?

http://cryptomining-blog.com/3893-updated-ccminer-1-5-git-fork-by-tpruvot-with-extra-nonce-support/

This is the tvpouvet version without some of the optimalizations. Do you have disconnect problems in this version?
What do you get in benchmark mode?

Ok with nicehash/westhash & p2pool. Problem with yaamp.com

Win7x64. Nvidia driver 344.75. GTX 750Ti. GPU Clock: 1210 MHz / Memory Clock: 1600 MHz

benchmark (970) is:
X11 - 7.3
X13 - 5.4
X15 - 4.7

Is this with standard clocks?

I think the release 8 did 6,7 MHASH@x11 on stock clocks(970) does it meen a  600KHASH Boost?

jpouza, are you there? Please post the 980 OC results

Hi sp_!
Here are the results with maximum overclock, about 9,5-9,7MH/s, some disconnects happening as mentioned by the guys before:

EDIT:
And keep going, nice so far , pool reporting proper hash, everything OK.

It is for EVGA SC GTX 970 ACX v.2
http://www.evga.com/Products/Product.aspx?pn=04G-P4-2974-KR
Non-overclocked, but its stock clocks are a little higher.
Will test tomorrow with yaamp and nice/westhash when rig rental is over.

sp did you optimize x11 in release 9
I've jumped to 7700 khash now (with 200 MHZ OC) on gtx970

[sp_]

jpouza: From the picture I see that you get a couple of does not validate on the cpu. Did you clock it too high? 9600 KHASH is i monster hashrate btw

Need to check the  "does not validate" , seams to work fine on the 750ti. This might be a problem with the ccminer52.exe file. Is the ccminer.exe performing the same as the 52 version?
