I am not much of a talker but I would appreciate if could get some assistance. I have a 14.1" T61 widescreen and I would like go for this mod. I might be few years late

1) Flash BIOS
2) cut trace at motheroard
3) solder one new trace (someone posted a picture that has a green wire)
4) solder second new trace (D22)
5) cut or isolate pins from QuadCore CPU
6) flash RAM if problems (or flash RAM as first step to avoid problems)
The problem is that my motherboard does not have D22. I believe totoro_kun and pentode has succesfully made this modification in T61 widescreen and it should be possible. Are all the modifications at motherboard mandatory and what are my options for a workaround ?
I have QX9300 CPU and modified BIOS files awaiting. I am now running X9000 overclocked @3,6GHz with advanced dock 2503 +Radeon RX560, 8Gb 800MHz RAM. I don't care about battery life since I keep it as a static installion for gaming and I don't have problems with temperatures or fan noise. I just feel I need to squeeze every last drop from this wonderful machine. I also have couple spare T61s if I screw up soldering.
Anyway, I would be glad if someone could show me the right way with this.
