Also, does memory amount on gpu matter?
For scrypt? Not so much, but for scrypt-jane it does matter.
Is Scrypt jane heavily dependent on memory available? If so how are 6GB Titans performing?
I think Titans have a problem allocating all that memory.
Quoted from the Scrypt-jane spreadsheet:
"GPU Memory usage: 2883 MB"
"Seems Kepler Kernal has better memory allocation then the Titan for Scrypt-Jane. Texture Cache set to -C 1 throws an error indicating it fails over to -C 2 but if you launch a -C2 the hashrate is nearly halved."
Edit: Also "Current Titan kernal appears not to allow much more then this before driver soft crashes currently."
Sorry im very noob into this, would be nice if anyone would post a working version for Gpu/Windows 64

I believe one was shared a couple of pages back.
I now have 30 kHash/s working for me. I think I am pulling more than a kilowatt of power now. Eeek. I am global warming.
More like global warning..... to ATI/AMD!
........ok, I stop.
