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
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
