Anyone having any luck with UTC now that the numbers went through the floor? Or would this even work over there?
My 750ti's were getting like 75KHash/s each after the increase. What are you getting with your mods and 750s after the change?

Before the change in N-factor over the past day or so, I was getting 60kh/s on UTC (and 300kh/s on normal scrypt so you can roughly judge my overclock on the the card).
The setting for UTC I was using before the n-factor change was...
-l T5x11 -b 4096 -i 1 -a scrypt-jane:UTC
What command line switches and OC on the card were you using to achieve 75kh/s?
At the moment with the same switches I'm only get 1.35kh/s
Apparently I was exhausted last night, and mis-stated the total as each card and not total.
I am getting ~19.10 khash/s for each card after the switch, and 75.80 khash/s total for 4 x 750 ti cards.
That being said it still seems more than what you posted, so here is the config I was using if it helps you.
Sorry for the confusion.
cudaminer.exe -a scrypt-jane:UTC -m 1 -i 0 -H 2
Autoconfig chose T31x1.

Speaking of having an edge.
It seems that at scrypt:64 the nvidia are doing rather well.
My gtx780ti is faster than the amd (not comparing to mine... which does not work well with scrypt getting only 6.4Mhash/s) and gets higher than 8MHash/s.

Hi Christian,
This coin seems to at least start the algorithm with Fugue. Maybe something extensible for ccminer?

Don't know if can say or not but was curious if you have early access to Nvidia's new driver 337.50?
Edit: Just meant to see if it made an increase in mining. I didn't mean to try and get early access.

no early access for me. Occasionally I get heads up about upcoming fixes (and non-fixes) for
CUDA versions and driver versions, but most of the time I am asked to keep it confidential.

It probably doesn't get said enough, but I want to thank the two Christians for working on the CUDA projects and accomplishing so much.
that's right!
they are the reason why I started this crazy hobby with a bag of 750ti's in the basement.
thanks!

It is a lot of fun watching where this is going. You are both extremely talented.

we're working on a KILLER groestl, requiring a deeper understanding of the hash algo.

I did some benchmarking and tweaking of the ccminer code and was able to squeeze out a 5% hashrate increase mining HVC out of my 750 Ti rig (+800 khash/s per card). Not a big advancement but I think it's pretty good for a guy whose name is not Christian 
I was mining Ultracoin today and just went over there on a whim, and of course the N factor went up just a little bit ago.

Yeh, and the scrypt miners coming very soon. Scrypt is a lost dream to nvidia.
well... yes and no... there are so many scrypt coin which are released... that it is always possible to find something which doesn't interest the whales... Takes Spartancoin for example. At the moment no exchange (hence small hashrate), large block reward, but should get soon on an exchange. Even at one sat, it is profitable. Another one Comedy Gold coin started as a joke on april fool day (I have something like 80millions) but there is a chance it get to an exchange... etc...
Scrypt coin (and most coin) it is just a question of timing. There is no point to go the big hype coins because even at start it will be difficult, but the small one are perfectly accessible (between launch and exchange time)
You can get few millions easy and even at 1 sat. it is still interesting

Anyone wanna help me figure out why ccMiner isn't hashing?
I have a 6 x 750TI rig, and I'm wanting to mine HVC. My .bat looks like this:
ccminer35.exe -a heavy -o stratum+tcp://<> -u <> -p <> -v 512
It connects to the stratum and starts detecting new blocks however this is the only output on the window.
Binding thread 0 to cpu 0
Binding thread 1 to cpu 1
Binding thread 2 to cpu 2
Binding thread 3 to cpu 3
Binding thread 4 to cpu 4
Binding thread 5 to cpu 5
And that's it. It never actually starts hashing, and yet the stratum keeps detecting new blocks.
Also via Hardware Monitor I can see that none of my cards are under any load at all.
Thoughts?

I've tried google and in site searching and keep coming up empty handed for some reason, I've got 6 gigabyte OC 750ti's and USB risers and can't get windows 7 or 8 to be happy with more than 4 cards. If I go 6, 2 will show yellow bullets. I would greatly appreciate some links or quick advice around this, I know it's something I am missing.
Thanks

I had initially removed support for all Compute versions except CC5.0, but I was able to get CC2.0+ compiled. Alas, I have no way to test whether this fork will work with CC3.5 and below, or on Windows for that matter. Therefore I can make no guarantee of your success if your rig uses either or both.
If you're brave, you can checkout my fork or view the full diff of changes..
Summary of changes:
* Compiled with CUDA 6 RC
* Made modest changes to hefty1 kernel. Honestly not sure these even made a difference; the original code from the C+C hash factory was already damn near perfect
* Changed code compilation
* relocatable device code support
* explicit linking via nvlink
* Removed maxrregcount to let compiler choose register count
My testbed specs:
And some performance metrics:

Current profitability status report for you guys. This is 8x 750Ti's.
Judging by that I should be mining fuge, i've got 6 x 750Ti's, which settings are you using and which is best pool?
ccminer35.exe -a fugue256
How about trying infinitecoin? Price is undervalued IMO and difficulty is 0.3-0.4. Almost mined out but new client allows mining of transaction fees. http://infinitecoin.com
Not so good of an idea for nvidia miners, specially 750 ti cards. scrypt is amd's territory, specially with the amount of miners and farms that mine scrypt already.
