Hi, as I promised I post the results of my modification at DV6, I finally finded time to disassemble it and tryed the spare parts that I ordered. QX9300 work flawless with the new DV7 motherboard, it is recognized and turned on at first attempt and it fit in the case as I supposed, the only thing is the Battery connector that is positioned bit ahead, and must be performed some modification at plastic case, I still didnt do that anyway cause first need to solve the heat problem; CPU in IDLE status is about 38-40° C, but under heavy load reach also 90+, and same thing and even worst for VGA, that reached about 100° C, I guess that heatsink of DV6 is not adeguate for the thermal request of these new components. I just have order the one of DV7 (Quad Core version) and I will see what happen I will updated you. Another good news is that MODDED Firmware for my old DV6 that I got here work as well in this board, the board still have F24 so I can update at modded F46 one. Hope that the new heatsink will do the job and I will finish the updates at this amazing laptop.
PS. I tryed to install F26 Modded Bios and work flawless, now I have all advanced option there and whitelist removed. Also AMD Mobility driver seems to fix High temp GPU issue, now is fixed at 45°. I put on also ThrottleStop and undervolt CPU at 1.050V, it pass also stability test, and temp do not exceed 75°, but anyway PC is still open... I wait the new heatsink for full test and to close it.
PS2. Another problem that I found but I guess I can solve it is the switch of touchpad, are shifted in another position in layout of this motherboard but there are too the empty position for my layout, so I need to weld it in correct position as you can see in this pic.
