What is the average speed difference for scrypt mining between the GTX 750 and GTX 750 ti? Guessing 260 to 300 KH/s @ $110 to $155? Does the extra 1GB memory make that much of difference?

may-be on yaccoin

Right, so-what's the actual KH/s for a GTX 750? Couldn't find on spreadsheet.
I got about $220 to spend. One GTX 750 ti or two GTX 750's. ;-)
Opinions?

Later I will try but exactly what means F4x16 and F2x8
What these value means?

Hi Cristian, how about new release?

tonight then. After the update performance will be approximately like this.

6x 750 Ti= 510 MHash/s = 3 x 780Ti   (all not overclocked, on Linux)

previously it would take you 12-15 750Ti's to get this hash

Is the new release going to bump the performance of 780's and 780 Ti's?

I'm currently getting about 180 mh/s on my 780 and 250mh/s on my 780 Ti. Even then I'm not using 100% of my graphics cards. They're hovering around 90% to 95% usage with or without Chrome or flash open.

So I think that my hasching speed is arount 24 khash/s (is it so low as value to do something concrete?) and, at first stage I have to change it in 12 khash/s

But what exactly have I to do to perform this operation? You say to me that I haveto reduce the -l...ok...but if execute:

cudaminer.exe --help for the -l paramether it say to me:

Code:

 -l, --launch-config   gives the launch configuration for each kernel
                       in a comma separated list, one per device.

So it seems to me that it is not related to the hashrate speed...

What am I missing?

Tnx

See this [2014-03-21 18:57:45] GPU #0: using launch configuration F4x16. Try run with -l F2x8

I have read the documentation about the Cuda Kernel but seems don't work because after that I execute my CudaMiner application using this statment:

So the hashrate velocity reach the 20,14 khash/s (that is very near to the banchmark value that was 24 khash/s)

Some ideas about how reduce more?

[ivanlabrie]

You won't get anything decent out of that laptop gpu...maybe try yacoin?
How much ram does it have?

Try reduce kernel load more.

 any thought on spartancoin ?
Just solo mine 2 blocks

[Mek]

I tried getting source code from git and compiling cudaminer myself to see how blake works there
I got it running after some time but I was surprised to get only around 42 MH/s on my GF GTX670M.
cgminer is much faster (250 MH/s) but that is still very low hashrate compared to the AMD cards which are equally powerful.
I just wanted to ask - is blake in some very early stage and will the performance be improved so we get more than using cgminer?

I'm probably going to try out Rotocoin. Launch is in about 3-4 hours.

2% premine, no exchange, no required data for N-factor coins, good luck to you!

[ivanlabrie]

+1 to roto...instamine won't last long.

[djm34]

Doesn't cost much, to do the launch and grab a few blocks. Just in case.

What would be the scrypt-n parameters though?
I have never been on a N-factor coin launch

you haven't been on any vertcoin, exe, gpuc ?  
cudaminer.exe --algo=scrypt:2048  -q -m1 -d gtx780 -b32768 -C2 -lt15x32 -i 0 -H 2

you might have to change the config though...

(try autotune first, I think for some cards the T kernel is better)

in case you didn't get the memo: nVidia sucks at compute bound hashing algorithms.
Factor 2 slower than AMD or so...

Now about the 42 MH/s vs 250 MH/s... I don't know how you compiled it. Custom builds
break the warranty ;-)

ccMiner v0.2 now supports pools with fuguecoin (like dwarfpool) and has a nice boost for Fermi and Maxwell owners.

cbuchner1, any chance I could get a small bit of help optimizing which version of cudaminer I should use for my gts250s? I'm just a small time miner but I'd definitely be willing to toss a small litecoin donation your way for some help!
