thank you very much largon and yiancar !

this is what i did not understand in which direction to read it.
so measure resistance x20 = trimmer.

got it up to 900 linked on ss-hope for 1000mhz+
little bit dissappointed from 55nm performance to 65nm-not much diff-only shader goes higher.
will report back with numbers from hwbot-got my 8600 up to 5700 on ln2 with only 1,65(1,592 load)-hoping for 6,0ghz in mark05.

thanks for your effort and time
jo from austria
