Xbox 360:Alternate Solder Points

Phat

3.3v, 5v, GND, and RGH 2 i2C

• J2B1
  • 

1.8V (Only if using an X360 ACE V1/V2/V3)

• Non-Xenon
  • 
• Xenon
  • 

PLL Repair on a Phat motherboard (required if bottom pad is damaged). Image credit to TheLazyITGuy.

CPU_RST

• C7R112
  • 
• R8C2
  • 

• J8C1
  • Will not work with EXT_CLK.
  • 

EXT_CLK

• Bottom (Under CPU)
  • 

FT6U1 POST (RGH 1.2 or EXT_CLK)

• Bottom
  • 
• Top (requires scraping)
  • 

FT6U7 POST (RGH 1, 2, or 3)

• Bottom
  • 
• Top (requires scraping)
  • 

GND

• J2B1 Header
• AV Port
• Any other ground point

PLL

• Bottom
  • 
• Top (under CPU heatsink; requires scraping)
  • 

STBY_CLK

• Top (Xenon)
  • 
• Top (Non-Xenon)
  • 
  • There are 2 points boxed; either can be used.

• Bottom (Non-Xenon)
  • 

SMC

• POST and PLL (Bottom)
  • 
  • Alternative SMC_PLL (Top)
    • 

Trinity

3.3v, 5v, GND, and RGH 2 i2C

• J2C3
  • 

CPU_CLK (Only if using an X360 ACE V4/V5)

• Top (HANA)
  • 
  • There are two points circled for C1 and C2 respectively; either can be used or bridged.

• Bottom
  • 

PLL

• Bottom (Requires scraping)
  • 
  • No alternative point!

POST & RST

• Bottom
  • 
  • There are two RST points, either can be used.

• Top (without postfix adapter, requires scraping)
  • 
• Top (with postfix Adapter)
  • 
  • A Postfix adapter can be used on Trinity in case the POST point is damaged.
  • The post pad you use on the adapter does not matter, as they connect to the same spot on the CPU anyway. It was only used for tuning the boot times of early I2C RGH methods.

STBY_CLK

• C3B10 (Top)
  • 

• FT3N2 (Bottom)
  • 

SMC

• The GPIO used for SMC_PLL is also used for Muffin/Mufas
• SMC_PLL
  • Bottom
    • 
  • Bottom (Alt point, requires scraping)
    • 
  • Top (Alt point; preferred for Muffin/Mufas)
    • 
• SMC_POST
  • Bottom
    • 

Corona/Waitsburg/Stingray

3.3v, 5v, GND, and RGH 2 i2C

• J2C3
  • 

CPU_CLK (Only if using an X360 ACE V4/V5)

• Top
  • 
• There are two points circled for C1 and C2 respectively, either can be used or bridged.

PLL

• Bottom
  • 
  • No alternative point!

POST & RST

• Bottom
  • 
  • There are two RST points; either can be used.
• Top (without postfix adapter)
  • 
• Top (Postfix Adapter)
  • 
  • If POST on the bottom is disabled (like in Waitsburg & Stingray boards) or damaged, a postfix adapter is required.
  • The post pad you use on the adapter does not matter, as they connect to the same spot on the CPU anyway. It was only used for tuning the boot times of early I2C RGH methods.

SMC

• The GPIO used for SMC_PLL is also used for Muffin/Mufas
• POST and PLL (Bottom)
  • 
• Alternate SMC_PLL (Top, southbridge. Requires scraping.)
  • 
• Alternate SMC_PLL (Top, DB2G3)
