so, now the soldered VMem-Mod is done
the results are with GPU= 790 MHz:
VMem-stock= 804 MHz / Aquamark3-tested
VMem-now= 873 MHz / Aquamark3-tested
the resistant-Ohms are
stock=610 Ohm
adjust.=565 Ohm (25 KOhm-poti)
V is calculated (not measured)
stock=1,75 V (?)
now=1,93 V (?)
(the solder-points are solder-friendly substitue-points)
so long
