CCminer(SP-MOD) Modded GPU kernels.

[CapnBDL]

Hi,

Ok, can someone tell me who has the best version for a GTX750Ti2Gb and where to find it...please? I've been running ccMiner version 70 and getting a consistent 3123kH (OC & hot). Is there a better one for x11 now?


Thanks much!!!!



edit: missed typed.....it should have been version 40.

Thanks...I'll give it a try. What might I expect to see? (so I can get an idea).

Depends on the card and the clockrate.  Gigabyte black with overclock should do around 3.2-3.3MHASH.

It's an ASUS card. I can get those clocks but the system becomes unstable if I try to do anything else but mine x11. Using GPUtweak /w clock of 1256 and mem of 5446, I can still get to mail and browser /w it being video slow but usable. It (v41) gives me just a small boost compared to v40. It's all good! Still over 3.1Mh. Not gonna complain. Keep up the good work!


Thanks

edit: Anyone know what happened to xHash.net? Not running for me, can't even get the homepage to come up.

I have submitted my modded Whirlpoolx to github. Building version 42

[sp_]

-Added Wirpoolx and optimized a few percent. (uint2 rewrite)
-Keccak +5MHASH on the 750ti
-tiny hashimprovements in some algos.


1.5.42(sp-MOD) is available here: (8-mar-2015)

https://github.com/sp-hash/ccminer/releases/tag/1.5.42

The sourcecode is available here:

thanks, but I get a scanhash_whirlpoolx out of memory on linux

Same here.  Dual 750Ti Ubuntu 14.04

WHIRLPOOL COMMANDLINE--

What is the proper commandline for whirlpoolx on NiceHash?  Also, what is the default Intensity?       --scryptr

[sp_]

To fix the default intensity(linuxI) you have to change the hardcoded value 26U in the whirlpoolx.cuda file. I forgot to add support for the intensity parameter. Will do it later.

Guys, this kernal is very fast, very profitable and very free. Please donate some beers to the authors

Thank you.  How do you properly call the algorithm?   Is it "whirl", or "whirlpoolx"?       --scryptr

I haven't been able to mine whirlpoolx on NiceHash yet.  Right now it is the hottest algo there.  

NiceHash posted that they increased the security for DDOS attacks, and miners are complaining that they are being blocked.  Earlier this week NiceHash was offline for maintenance.

I use a JSON.conf file as below:

{
   "url" : "stratum+tcp://stratum.nicehash.com:3343"
   "user" : "bitcoinaddress.worker",
   "pass" : "d=0.02",

   "algo" : "whirlpoolx"
}

and call it with the command line "ccminer.exe -c JSON.conf" on Win7 x64 with a GTX 960.  I get about 128150 kh/s but no accepts.       --scryptr

This is working on my 960 using my build(42) on windows 7

ccminer.exe -a whirlpoolx -u 1CTiNJyoUmbdMRACtteRWXhGqtSETYd6Vd -p 1 -o stratum+tcp://stratum.nicehash.com:3343

but you need to wait some seconds, and then Nicehash will set the diff correcly.

My 960 is also getting abit higher hashrate. I use -500Mzh on the memoryclockrate.

-a whirlpoolx

Well done on WhirlpoolX - my 290X is doing about 520MH/s.

That is really good. my 980 is around 300MHASH with overclocking. I tried to rewrite to uint4 but it went slower. What did you do? did you remove the lookuptables?

I updated line 47 of x15/whirlpoolx.cu to be:
uint32_t throughput = pow(2,19);

That got rid of the memory error, but I've encountered another issue.  When I hash with both GPUs (both 750Ti) one GPU gives me a crazy hashing number, for example:
[2015-03-08 14:17:02] GPU #1: GeForce GTX 750 Ti, 667438585 kH/s
[2015-03-08 14:17:03] GPU #1: GeForce GTX 750 Ti, 661272871 kH/s
[2015-03-08 14:17:03] GPU #1: GeForce GTX 750 Ti, 658636297 kH/s
[2015-03-08 14:17:04] GPU #1: GeForce GTX 750 Ti, 657527143 kH/s
[2015-03-08 14:17:05] GPU #1: GeForce GTX 750 Ti, 658030840 kH/s
and fills up the screen very quickly with these values (I believe the other GPU at some point does output a valid looking hash, but it scrolls by so quickly).  But if I use the -d switch and hash with only one of the GPUs, I get proper values of:

brother. i confirm. i have the same issue with every source out there (linux version!).
