# Hardware with SGX Support

### CPU

SGX was first introduced in 2015 with the sixth generation Intel Core microprocessors based on the Skylake microarchitecture.

Lists with SGX feature enabled CPUs are maintained by Intel at:\
[SGX with Intel® ME](https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873&2_SoftwareGuardExtensions=Yes%20with%20Intel%C2%AE%20ME)\
[SGX with Intel® SPS and Intel® ME](https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873&2_SoftwareGuardExtensions=Yes%20with%20both%20Intel%C2%AE%20SPS%20and%20Intel%C2%AE%20ME)

Some of the initial 2015 released CPUs do not support SGX. Only specific S-Spec support it. Please consult the table below:

### Motherboards / Compatible Systems

A list of SGX compatible systems that support Intel SGX is maintained here: <https://github.com/ayeks/SGX-hardware>

Starting April 2025, only Hardware with [FLC](https://software.intel.com/en-us/blogs/2018/12/09/an-update-on-3rd-party-attestation) is needed to be part of the mainnet, for the testnet SGX1 without [FLC](https://software.intel.com/en-us/blogs/2018/12/09/an-update-on-3rd-party-attestation) can be used.

### BIOS

A bios upgrade might be necessary for your system to activate SGX support. Please consult the hardware manufacturer.\
SGX must be set to ENABLED in the system BIOS.
