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

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?
Read >>> About CUDA Kernels <<< in README file

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/sBut 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: -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 Later I will try but exactly what means F4x16 and F2x8What these value means?

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?

Try reduce kernel load more.

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?

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

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 ;-) Christian

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!
