Just a quick question, for this Gigabyte GA-Z68MA-D2H-B3 board http://www.newegg.com/Pro...x?Item=N82E16813128495 it doesn't say in the details that it has internal USB 3.0 headers, however in the picture here's what I see...
Can someone confirm that it is indeed a USB 3.0 header? I just bought the Solo II case and need a budget board that can make use of the front panel USB 3.0 headers. This is all gonna be for my secondary rig btw!
That is a Trusted Platform Module (TPM) header.
Here's a brief description of the purpose of a TPM:
Computers that incorporate a TPM have the ability to create cryptographic keys and encrypt them so that they can be decrypted only by the TPM. This process, often called "wrapping" or "binding" a key, can help protect the key from disclosure. Each TPM has a root "wrapping" key, called the Storage Root Key (SRK), which is stored within the TPM itself. The private portion of a key created in a TPM is never exposed to any other component, software, process, or person.
Computers that incorporate a TPM can also create a key that has not only been wrapped, but also tied to certain platform measurements. This type of key can only be unwrapped when those platform measurements have the same values that they had when the key was created. This process is called "sealing" the key to the TPM. Decrypting it is called "unsealing." The TPM can also seal and unseal data generated outside of the TPM. With this sealed key and software like Windows BitLocker Drive Encryption, you can lock data until specific hardware or software conditions are met.
With a TPM, private portions of key pairs are kept separated from the memory controlled by the operating system. Keys can be sealed to the TPM, and certain assurances about the state of a system—that define its "trustworthiness"—can be made before the keys are unsealed and released for use. Because the TPM uses its own internal firmware and logic circuits for processing instructions, it does not rely upon the operating system and is not exposed to external software vulnerabilities.
