Please realize that there is a certain risk involved with overclocking, including adjust-
ing the setting in the BIOS, applying Untied Overclocking Technology, or using third-
party overclocking tools. Overclocking may aect your system’s stability, or even cause
damage to the components and devices of your system. It should be done at your own
risk and expense. We are not responsible for possible damage caused by overclocking.
Due to limitation, the actual memory size may be less than 4GB for the reservation
for system usage under Windows® 32-bit operating systems. Windows® 64-bit operat-
ing systems do not have such limitations. You can use ASRock XFast RAM to utilize
the memory that Windows® cannot use.
