Thank you so much Bufius, just let me know if I give the wrong credit in first page or in the website.
It is nearly OK, just change Trullala to Bufius (new nick, also in irc channel now
![Wink](https://bitcointalk.org/Smileys/default/wink.gif)
and give credits for source adaption to me and for windows builds to Aleks.
For everyone reading:
- yes, hashing speed is ~50% of normal scrypt because the main (memory and work intensive) loop is 2048 cycles instead of 1024 for normal scrypt.
- during the upcoming changes of nFactor, the hashing speed will half every time = every year
- for now, TC needs to be lowered to ~80% of normal scrypt (as a starting point). I cannot give a better estimation, need to understand cgminer and opencl code in general much better to do this.
- try to change TC to something like 256*x (for me this works OK)
- for my 7950s i use 19712 = 256*77 without HW errors @1000/1500
- 5770 is at 4096, also no HW errors @ 925/1350
- playing around with the lookup gap is also possible if HW errors occur, but everything != 2 lowers performance.
- increase to 4 or 8
