  • TPM 2.0 module adds hardware encryption for Windows 11 upgrade
  • SLB9665 chipset provides independent secure storage for sensitive data
  • 20-pin LPC header fits listed Gigabyte AX370 and AB350 motherboards
  • Also compatible with listed Gigabyte A320 series desktop boards
  • Resolves TPM 2.0 verification issue blocking Windows 11 installation

TPM 2.0 module with 20-pin header

This discrete TPM 2.0 module uses the SLB9665 chipset and connects through a 20-pin LPC header. It is designed to add a hardware trusted platform module to compatible desktop motherboards. The unit functions as an independent encryption chip for secure key storage and platform integrity checks.

Builders adding Windows 11 support to older boards

The module targets owners of older Intel and AMD desktop motherboards that lack firmware TPM and have a physical 20-pin TPM header. It will not work with newer motherboards that already implement firmware TPM, nor with all-in-one systems or laptops. Buyers needing a module for a different pin count or form factor should look elsewhere.

20-pin LPC header compatibility

Installation requires a motherboard equipped with a 20-pin TPM header wired to the LPC bus. The chipset is SLB9665 and the specification is TPM 2.0. Verify the header pin-out and BIOS support before purchase.

Questions about this item

Does the SLB9665 TPM 2.0 module draw noticeable power or generate heat when the system runs all day?

The module is a small LPC security chip that consumes negligible power and produces no perceptible heat during continuous operation.

What must my motherboard already have for this 20-pin TPM 2.0 module to work?

Your motherboard needs a 20-pin LPC TPM header and must be one of the listed Gigabyte models such as the GA-AB350-Gaming or GA-A320M-S2H.

Will this TPM 2.0 module function alongside the older Gigabyte GA-AB350-Gaming motherboard I plan to keep?

Yes, the SLB9665 is designed for that exact board and other 350- and 370-series models, providing the firmware TPM 2.0 required for Windows 11 upgrades.
