Latest version on X11,x13,x15 i'm getting a CPU does not validate, all other algos are ok.
previous version was working fine

Note that the exe is build without compute 5.2. If you have a 960/970/980 card you should eighter build yourself or wait for another build.

The cuda version I am using doesn't support compute 5.2 and it takes forever to download on my mobile link in Thailand.

GTX 960 and X11--

My GTX 960 on Win 7 x64 runs 225+ kh/s faster with X11 (5740kh/s v 5515kh/s), but gets nothing but "does not validate on CPU" errors with no accepts.  I reverted to v42 after a very short trial.       --scryptr

Download the binary from here:

My version is buildt with an older version of cuda 6.5 wich doesn't support compute 5.2

I downloaded the crypto-blog version.  I assume that it was compiled by a friendly third-party.  It is currently mining X11 at 5545kh/s on my Win 7 x64 GTX 960.  This result is compared to 5515kh/s on your last release of v42.  I suppose my earlier (and unsuccessful) results gave a larger, but false, increase in hash rate for v43.

Thanks for your continued programming efforts.        --scryptr

With 1.5.43(sp-MOD), I'm getting 50-80 watts lower than 1.5.42(sp-MOD) with some better performance on Whirlpoolx, even without being optimized for Compute 5.2. I did not recompile.

Try the version compiled by the cryptomining blog. Faster? how many watts?

I didn't tweak the parameters on compute 5.2 cards yet.

in the file:

cuda_whirlpoolx.cu

you can try to alter these values:

#define TPB 512
#define NONCES_PER_THREAD 8

tpb must be a number above 256 and dividable by 32

you can also search for __launchbounds in the file and change the ,3 to something else.

The gtx 980 is doing 200khash bether mining x11 from release 42 to 43. What are you getting on the 960? Did it work with the other build?

3RD PARTY BUILD-

OK, the v43 build you released did not work on my GTX 960.  You posted regarding the difficulty downloading CUDA requisites.  The 3rd party build of v43 does 30kh/s better than your release of v42. Your build of v43 gets 200kh/s better, but with no accepted shares, and "does not validate on CPU" errors.

My German is more limited than your English.  I tried to use simple statements.  It is entirely possible that the 3rd party build is slower than what your build could truly do.  In fact, I hope that is the case.          --scryptr

I have submitted a bugfix that might fix the issue. Remove compute 5.2 from the project file and rebuild. Should give correct results now.
Don't know if it will run faster though...

submitted a 3khash increase in x11 (750ti)

The current launch config is incorrect. you should get around 300MHASH if you change it a bit on the gtx 980 with overclock.

Still far behind wolf0's 290x whirlpoolx kernal. (450MHASH)

My 290X kernel does 660MH/s, not 450MH/s.

Because of the kind darkcoin donators a fistful of darkcoins has now turned into a fistfull of fiat.

So DARK coin is now officially DASH.

Good work sp  on #43  quark ~ +50kh/s to +75kh/s and ~ 5 watts less on electricity.  X11,X13,X15  increase on hash too.

X11 HASH RATE--

After a cold reboot of my system, I am getting 5575kh/s on my GTX 960 with the cryptoblog build of v43.  Any load on the system will lower the kh/s result, but the hash rate is consistent when no other load is taxing the system.  This is a 60kh/s increase from v42, which topped out at 5515kh/s for X11.  X11 is presently a top earning algo.       --scryptr

Greetings
What is the best one to mine CryptoNight algo? I have 2 X 6 X GTX 750 ti and have decided to take them out of hibernation and put them to work. I have been out of the loop for too long and have no idea where to look and what to use. Help appreciated.
Danka

My private kernal is the best. I am selling it for a 0.2BTC donation. It also includes a fast spreadcoin miner with full sourcecode.

[sp_]

today I rewrote whirlpool in x15.

+15KHASH on the 750ti.

Submitted to github

[Grim]

Is anyone mining darkcoin (dash) here ?
Blockfinder only gets about 60% ...

Therefore any mining calculator is WAY off.

?

sp_,

Any updates soon on the cryptonight donation miner?

[sp_]

Don't have the sourcecode here, but I will spend some time on it when I get back.

Sold a darkcoin masternode.

my vacation is extended $$$

What values did you set that gave you 300 mh/s on the 980?
