this is what I get on my 660Ti under Linux.

I wonder, if it is really good for the coin all that...

I think it's good for all crypto if @ least one coin make nvidia cards owners join the game... And I say that as an Ati farm owner...

[djm34]

ok here we go:

COuld you please share the download with the rest of us windows users? Thanks

+1

There will be an official release at 7pm...

Actually, nvidia cards are are already ahead for script-jane Nfactor=9 (or at least pretty close)

I settled for maxrregcount=96 in keccak.cu.  Using __launch_bounds__ directives I make sure the other keccak512 kernels (for scrypt-jane) remain at 64 registers so they keep working.

Maybe some guys will want to test the Linux based Makefile.am (run ./autogen.sh) and run it on ther GTX 780's, Titans, 780 Ti's and GT 640 with Compute 3.5 ?  You can go up to x24 launch configurations with this register count on Compute 3.5 devices. And hopefully we'll get into the >400 kHash/s range

how do we test this christian? sorry i am a little slow today, compile as normal?

Ok guys I have a couple of gts 450 1gb, what cuddaminer should I use for maxcoin? the default download from page one or a special ed (link if possible)?

Could you advise me on abat file configuration?

I am on windows!

[cbuchner1]

Me want! Christian I think something must be throttling back the 780 to the 780ti. There isnt that much performance difference and right now its over a 300Mhash/s difference

it's the maxrregcount option during compilation.

yes, right from github. Don't forget the ./autogen.sh

I haven't modified the Visual Studio 2010 solution's maxrregcount yet!

ok downloaded directly from github, compiled as normal. Results;

yehhhhh

im getting results as high as 67million khash/s

using ./cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark
i am still getting 4.6million khash/s

in term of Hashrate / price ? I don't think so...

improbable. probably broken launch config.

[bigjme]

using ./cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark
i am still getting 4.6million khash/s

that being said, every 3 attempts it does nothing,
so its saying

4.6million khash/s
4.6million khash/s
0 khash/s

[cbuchner1]

using ./cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark
i am still getting 4.6million khash/s

try x16 x20 x21...

x22 might already exceed the register file's 65536 limit because 96 registers per thread x 22 warps x 32 threads/warp > 65536.

[djm34]

you have one line at 0 and the next 1.6G

[cbuchner1]

you have one line at 0 and the next 1.6G

yeah don't trust numbers that are so obviously suspicious.

I am not even sure if I can trust the 450 kHash/s that someone was reporting on Windows.

[bigjme]

./cudaminer --algo=keccak -d gtx780 -L 16 -l K192x22 --benchmark

115Mhash/s

and thats why i posted the screenshot :-)

EDIT:
so i just ran tests from
/cudaminer --algo=keccak -d gtx780 -L 92 -l K192x32 --benchmark
down to
/cudaminer --algo=keccak -d gtx780 -L 92 -l K192x24 --benchmark

changing the x** number down 1 each time. anything higher then x24 gives me stupid numbers, 24 gives me 126Mhash/s, and i lost about 5Mhash/s for every x** i take off after that

oke cbuchner1  thanks for updating, do you have perhaps a good setting for my poor Evga GT610 2 GB card ? i cant get it higher then 7.5 khash/s !

I do not think this device can be much faster. 48 CUDA cores on what I believe to be a single Compute 2.1 multiprocessor.

As you see it's already putting out more heat than your fan (or passive cooling) can transport away.

yep correct i did know that nut perhaps could it be better , saving for other card i think , thanks m8

[rtm]

Can some one help me with gt640 2gb?
I try with
cudaminer --algo=keccak -d gt640 -l K2x32 --benchmark

K2x32 is from autotune without --algo=keccak
When i put --algo=keccak and the miner says "try cudaminer --help"

[FlyingLotus]

ok here we go:

:O

Is this legit?

What do you reckon for 2x670s?

[cbuchner1]

K2x32 is from autotune without --algo=keccak

keccak requires a less than 24 hours old development build, and autotune does not yet tune for keccak, but for scrypt.
