745823-B21 – TPM 2.0 20-1 Pin LPC Module for Gen9 Servers
Discrete TPM 2.0 add-in kit for systems that use the 20-1 pin LPC “TPM” header. Provides a hardware root-of-trust for BitLocker/Device Encryption, measured boot, and platform attestation on UEFI systems.
Description
The module plugs directly into the motherboard’s LPC TPM (20-1) header and exposes a TPM 2.0 device to firmware and the OS. Designed for Gen9 server platforms that require a removable, discrete TPM rather than firmware TPM.
Technical Specifications
- Interface/Header: LPC, 20-1 pin keyed (2×10 with one missing pin)
- TPM Standard: 2.0 (TCG 2.0)
- Form Factor: Small vertical daughtercard, direct plug-in
- Functions: Secure key storage, RNG, PCR/attestation, measured boot
- Firmware/OS: UEFI required; enable TPM in system setup

✅ Confirmed Compatibility
Please note that the following list is not exhaustive. Compatibility depends on your system’s specific configuration. It’s essential to verify compatibility with your system or enclosure manufacturer prior to installation.
✔️ Gen9 rack/tower servers that specify support for the TPM 2.0 kit 745823-B21, including common models such as DL360 Gen9, DL380 Gen9, DL160 Gen9, DL180 Gen9, DL580 Gen9, ML350 Gen9, ML150 Gen9, ML110 Gen9 (and other Gen9 systems listing this kit in their documentation)
☑️ Key Features
- ☑️ Hardware root-of-trust for encryption keys and credentials
- ☑️ Direct 20-1 pin plug-in—no cable required
- ☑️ TPM 2.0 support for modern security and compliance workflows
- ☑️ Purpose-built for Gen9 server platforms
⚙️ Fit Notes
- Requires UEFI mode to utilize TPM 2.0 features.
- This is the LPC 20-1 style module; it is not compatible with 14-pin LPC or SPI_TPM headers.
- If a TPM 1.2 module is already installed, replace it only if the platform documentation allows it.
- After installation, enable Security Device/TPM in BIOS and clear/initialize if the OS prompts before enabling BitLocker or similar features.
