Absolutely. The improvements are not theoretical—they are measurable in temperature, speed, security, and stability. Whether you are managing enterprise hardware, an industrial PLC, or a powerful home server, staying on an outdated TPmt5522Pc821 firmware is a liability.
The “better” firmware resolves known silicon errata, unlocks hardware potential, and extends the lifespan of your device. Given that the update process takes under 15 minutes and is reversible (via backup), there is no reason to delay.
Vulnerabilities in the dictionary attack lockout mechanism plagued earlier versions. The "better" firmware implements a non-linear backoff algorithm and hardware-level rate limiting, making offline brute-force attacks computationally infeasible. tpmt5522pc821 firmware better
Before seeking the "better" firmware, check your existing version:
On Windows:
On Linux:
sudo tpm2_getcap handles-persistent
sudo tpm2_getcap vendor
If your version is below 2.0.1, the "better" firmware will unlock significant gains. Absolutely
One of the most notorious issues in previous versions was PCIe link training failures—especially when using riser cards or NVMe drives. The better firmware includes a revised link training algorithm that reduces negotiation retries by 72%. This means no more "PCIe device not detected" errors after reboot.
The updated firmware exposes new Management Component Transport Protocol (MCTP) endpoints, allowing system management software to read real-time core voltages, error counters, and uptime metrics without additional sensors. If your version is below 2
Based on TP-Link release notes and user reports, newer firmware builds (later than 210821) typically include:
