About the 461-AAIG
The Dell 461-AAIG is a Dell Trusted Platform Module (TPM 2.0) Security Module for 14G/15G designed to provide hardware-based cryptographic security for Dell PowerEdge servers. The 461-AAIG stores encryption keys, platform measurements, and certificates in tamper-resistant silicon, enabling Secure Boot, BitLocker drive encryption, and hypervisor attestation.
Compatibility
The 461-AAIG installs into a dedicated motherboard TPM header on Dell PowerEdge R740, R640, R750, R650 servers. Once bound and enabled in system BIOS, the 461-AAIG establishes permanent cryptographic pairing with the host motherboard as governed by platform security standards.
How to identify a genuine unit
Genuine Dell 461-AAIG TPM modules display a miniature serialized label showing DP/N 01Y28P and regulatory compliance markings. In system BIOS and iDRAC System Security inventory, the 461-AAIG module enumerates as TPM 2.0 with active firmware and PPI status, verifying cryptographic hardware readiness.
Buying used
Note that Dell TPM modules like 461-AAIG are cryptographically paired to the host motherboard upon activation and cannot be reset or moved to another server once enabled. Pre-owned 461-AAIG modules must be verified as brand-new, uninstalled spares with undamaged connection pins.

FAQ
Can a used TPM 2.0 module be installed on a different server?
No, Dell motherboards permanently bind the cryptographic security token to the TPM chip upon first boot; used TPMs cannot be reused on another motherboard.
What is the tamper screw/rivet included with the module?
It is a one-way security rivet designed to physically lock the module to the motherboard to prevent unauthorized physical removal.
