XMP (Extreme Memory Profile) is a preprogrammed profile by Intel that enable you in BIOS to set the correct memory settings in a easy step. XMP is exclusive for Intel platforms only.

DOCP and A-XMP is similar program with XMP, but designed for AMD platforms.

We do not recommend mixing memory kits, regardless of brand or model.

By mixing memory kits together, there may be compatibility issues such as unable to boot or unable to operate at rated specifications.

Each of our memory kit are thoroughly tested to ensure compatibility within each memory kit.

And because we have not tested our memory kit with your existing memory kit, we cannot guarantee compatibility when multiple kits are used.

If your operating system is 32-bits, then it cannot use more than 4GB of memory. Please upgrade to a 64-bit operating system to use more than 4GB of memory.

If your Windows 7 operating system is 64-bits, then please check the Windows version. Each version has a maximum limit:

Windows 7 Home Basic: 8 GB; Windows 7 Home Premium: 16 GB; Windows 7 Professional: 192 GB; Windows 7 Enterprise: 192 GB; Windows 7 Ultimate: 192 GB

If your Windows 7 operating system version is correct, please check that Windows is not limiting your RAM usage. To check, go to the “Run…” dialogue, type “msconfig”, and press Enter. Then select “Boot” tab and click on “Advanced options…” button. Please make sure “Maximum memory” is not checked, then click “OK” for all dialogue boxes and reboot your system.

Windows 8, 8.1, and 10 has a higher physical memory limitation beyond configurable memory capacity, so 64-bit versions of Windows 8, 8.1, and 10 should not experience limitations on physical memory capacity.

Windows 8: 128GB; Windows 8/8.1 Enterprise: 512GB; Windows 8/8.1 Professional: 512GB; Windows 10 Home: 128GB; Windows 10 Enterprise/Education/Pro: 2TB
