Optimization anything about GTX950? I have three cards in wait. Yesterday I've been testing one of these babies. It reaches 8.77MH on quark with overclock... At how many watts plz.

master's whirlpoolx seems broken, it segfaults under linux...
I've PR'd a fix. If you can build yourself, you can pull down the branch at https://github.com/t-nelson/ccminer/tree/whpx_segv

It seems that compared to the 750ti, 950 and 960 scale +/-10% at around 133% and 200% respectively when you consider price, power and performance together. Price and power (and that goofy ass memory interface on the 970) start to discourage the higher-end cards.

750Ti still seem like a really good choice imo. I guess the prices will go down a bit also now when new cards show up ? Me myself are buying used 750Ti:s for like 80 bucks.
All my 750Ti:s produce around 7.1-7.3Mhs @Quark superstable.

still segfaulting... i also notice it segfaults even with the -h or -V flags too after printing out the infos and curiously it doesn't when started inside gdb (it starts hashing normally)

I don't have a pool for that so only tested with -a whirlpoolx --benchmark. I came across that other mess of crashes you mentioned. Uninitialized globals galore! See https://github.com/t-nelson/ccminer/tree/sigh. I'll PR it once I test build on Windows.

Or if it's public/anon pool you can just PM me your credentials and I'll throw some hashes at you to test.

I've spent the last week trying to get more out of my 6 x 750ti & all I can get is 6200 each and then its not 100% stable Can I ask how are you getting 7000 out of yours?

True. But when you consider the fact that you can only fit so many cards in one box, looking at performance per card starts to be a bit more important. One box with 6x 960 should be about the same (probably better) hash/watt as two boxes with 6x 750ti each, but with significantly lower upfront cost.

You need to use the release 65. The asus strix 750ti does 6,25MHASH on standard clocks. x86 windows. (the remaining 12% should be possible with overclocking) You can also use the new option -C to let the cpu aid the gpu as well (but it will draw more power)
