V8 Modbo modchip installation diagram

One of the revisions of the fat PlayStation 2 was the V8. They were found in many of the SCPH-3900x models. Matching console model numbers and board numbers are listed below.

You can find the model number on the sticker on the bottom of the console, and the board number is printed on the PS2 main board if you take apart your console. Note that there can be multiple board numbers within a specific model number.

  • NTSC-J (Japan):
    • SCPH-39000 (GH-019, GH-022)
    • SCPH-39006 (GH-019, GH-022)
    • SCPH-39007 (GH-019, GH-022)
  • PAL
    • SCPH-39002 (GH-019, GH-022)
    • SCPH-39003 (GH-019, GH-022)
    • SCPH-39004 (GH-019, GH-022)
    • SCPH-39008 (GH-019, GH-022)

Note that there are multiple versions of the Modbo modchips available, but the installation diagrams are all the same. Some example versions are Modbo 3.0, Modbo 4.0, Modbo 5.0, and Modbo 750.

Installation tips

Here are some tips I have for you when you are soldering your chip into a V8.

  • Using 30 AWG solid core wire works well for most of the points.
  • Use some thicker wire for the 5V and ground wires.

This first one is a GH-019 board (click on the image and then zoom in to see the details). There is some solder on some additional points because I removed an older modchip and replaced it with a Modbo 5.0 on this board.

This second one is a GH-022 board (click on the image and then zoom in to see the details). You can see that even though the BIOS chip has a gap in the pins the wiring is the same.

Hi!
I don’t know if anyone will see this these days but I’m following this guide and I have an issue. Everything’s gone fine except the pad that you wire to B somehow pulled off the board. Is this an issue? Is there an alternate place? Or can I just do it without?
Thanks
