Motherboards

Most motherboards have several sub-revisions which are also listed here for every revision. On fat motherboards, the subrevision is denoted by the number after the last hyphen in the item No. On slim motherboards, it is written after the board number (e.g. GH-032-11). For PSX (DESR) motherboards, see PSX motherboards. For arcade systems, see Arcade Boards.

Playstation 2 Fat Motherboard Models

GH-00X

GH-001

• Year 2000
• Models SCPH-10000
• Chassis A
• Japanese launch revision
• Always has a green solder mask, unlike later boards, which mostly have blue solder masks
• This board (together with GH-003) takes just 8.5 V as input voltage. NEVER install a 12 V power supply in these consoles!
• Incomplete BIOS (no DVD player); DVD player can be installed onto a memory card using an update disc
• Buggy DVD player (version 1.00) that allows region free (but 60 Hz only) playback using some trick as well as RGB-output during DVD-playback, which was disabled on later versions
• Later production models might come with an updated BIOS that blocks installation and startup of DVD player 1.00, as well as with an updated MechaCon (or updated calibration data in EEPROM, e.g. for speedier tray loading), just like GH-003 does
• On the CDVD Drive daughter board, GH-001 boards only support the Sony CXA2605R RF-Amp (daughter board GM-038)
• Known sub-revisions: 1-677-377-xx
  • -12

GH-003

• Year 2000
• Models SCPH-15000, SCPH-18000 (besides GH-008)
• Chassis A (in SCPH-15000), A+ (in SCPH-18000)
• First board to use a blue solder mask, as do most later boards (with some exceptions)
• This board (together with GH-001) takes just 8.5 V as input voltage. NEVER install a 12 V power supply in these consoles!
• Some small component changes (resistor packs instead of discrete resistors between EE and GS and some other places, some other small SMD components changed around GS and near the drive connector etc)
• In SCPH-15000, DVD player still needs to be installed first (in a newer, partially fixed version (v 1.01), that seemingly can also be used on SCPH-10000), but BIOS disallows use of the buggy version 1.00
• In SCPH-18000, DVD player is preinstalled (v 2.0)
• In SCPH-18000, it has a different boot-ROM installed on a daughter board on the bottom, while the normal bootrom pads are left unpopulated
• Updated MechaCon for speedier tray opening/closing
• On the CDVD Drive daughter board, GH-003 boards support either the Sony RF-Amp CXA2605R (daughter board GM-038) or the Texas Instruments SP3727A RF-Amp (daughter board GM-042), depending on which components are installed on this board at certain positions
  • on -21, a jumper labeled "TI" next to MechaCon identifies which RF-amp is supported; the jumper is just a marking and does not change anything electrically, while the actual differences are some other component changes
• Known sub-revisions: 1-679-266-xx

GH-004 + GD-011

• Year 2000
• Models SCPH-30001
• Chassis B
• US launch revision (together with GH-005)
• This board and all later fat PS2 boards take 12 V as input voltage
• Has DVD-player preinstalled, just like every later board
• Has alternate solder pads for either 2 separate ROMs for BIOS and DVD-player (informally known as no-gap-BIOS) or a single ROM containing both (informally known as gap-BIOS)
• Has a daughterboard (GD-011, not the same as GD-012 with GH-005) containing voltage regulators, Syscon, EEPROM, RTC (with battery) and CR2032 coin cell
  • The large 4-pin connection between the motherboard and the daughterboard is sometimes or always soldered and needs to be desoldered to take them apart; some consoles might have a different connector that can be disconnected, though
  • This connection carries high-current supply voltages for EE and GS; other voltages are supplied through the other connector
• Known sub-revisions: 1-680-109-xx

• Variant of K-chassis with separate EE and GS (requires different heatsink than GH-035!)

• Chassis L
• Variant of L-chassis with combined EE+GS
• Introduces new PPC 405 based IOP with external 4MB DDR-SDRAM, which emulates functions of the old MIPS-based IOP as well as SPEED; has some compatibility issues
• As the functions of SPEED were integrated into the IOP, having an SSBUS-controller became obsolete, thus the combined SSBUS-Controller + SPU2 chip (CXD2955R) that was introduced with GH-026 got "downgraded" to the older SPU2 (+SPU2 RAM) chip (CXD2947R), that was introduced way back with GH-017
