Try to connect vr to mod points on both PCBs. Then measure resistance. Lower resistance very little first. Example 1070ohm -->1000ohm. (ISL 6534)
Then boot your computer and measure voltage. If you don't lower resistance much, there shouldn't be any problems.
I'm back! :)
Did the mods on ISL6534 today on both PCBs and started with a resistance of 1018ohm. No artefacts this time, but i lowered resitance to about 850ohm and i got no voltage gain from it, so i presume it is maybe the Vddr mod? Or should i lower the resitance more? But i stoped there, bcs. if it is for the Vddr i will damage it, without any measuring point..
Should i try the mod now on the other IC?

Thanks for your reply in advance! :toast:
What a small GPU :) Pf its HUGE!:eek: :eek: :eek: :eek:
The card has DDR3, correct?
Stick the black probe of your multimeter into a black wire of a molex (ground), and with the red probe carefully measure voltage on the larger tan colored resistors in the volt modding area. Look for around 1.8-1.9 volts for a memory read point.
Found the point for Vddr now and lowered resistance to about 850ohm again, but nothing happened on Vddr too?! :p: What mod i did there..

1,920V on 1070ohm and 1,920V on 850ohm. :stick:
Ok, now Vddr works perfect on ISL6549CBZ, but i do not really need this mod. Please someone can recheck the mod for Vgpu on ISL6534CRZ?! :)
I already tried to understand it, by reading the specification papers from the IC, but i don't get it.. :(
Please guys! :clap:
Anyone want to help me plz?! :(
