Support request: TeamGroup T-Force Delta RGB DDR5 (Model FF3D532G6000HC30DC01, AM5 platform)

Description:

Technical note:
On AM5 motherboards, DDR5 RGB control seems inaccessible to OpenRGB because the memory’s SPD/PMIC bus is not directly exposed to the OS I²C controller. This may require adding SMBus access through AMD’s AGESA or another low-level method. Posting this for visibility and to help with DDR5 + AM5 support development.

Hello!
I’d like to request support for TeamGroup T-Force Delta RGB DDR5 memory modules.
The DDR4 versions are already supported, but the DDR5 variants aren’t detected on AM5 platforms.

System details:

  • Motherboard: Gigabyte B650 Eagle AX
  • CPU: AMD Ryzen 7 7700
  • RAM: 2 × 16 GB TeamGroup T-Force Delta RGB DDR5 6000 MHz
    • Model: FF3D532G6000HC30DC01
  • OS: Arch Linux
  • OpenRGB version: 0.9 + (1.0 rc2)

Observed behavior:

  • OpenRGB does not detect the DDR5 RGB modules.
  • The RGB stays on the default motherboard pattern.
  • decode-dimms and i2cdetect both fail to locate SPD/EEPROM addresses.

Relevant output:

[i2c_smbus_linux] Failed to read i2c device PCI device ID decode-dimms: No EEPROM found (even with eeprom/at24/ee1004 modules)

i2c-0 through i2c-17 present (Synopsys + AMDGPU), but no devices respond on 0x50–0x57

Notes:

  • DDR4 versions of T-Force Delta RGB are already listed as supported.
  • This DDR5 model might need new SMBus/PMIC handling for RGB detection.
