Final answer:
The speed of SDRAM can be increased without increasing the motherboard's system clock by overclocking, using faster memory modules, and optimizing memory settings in the BIOS or UEFI.
Step-by-step explanation:
The speed of synchronous dynamic random access memory (SDRAM) can be increased without increasing the motherboard's system clock speed by using a technique called overclocking. Overclocking involves increasing the voltage and adjusting the settings of the memory modules to achieve higher speeds.
Another way to increase the speed of SDRAM without affecting the motherboard's system clock is by using faster memory modules. For example, upgrading from DDR3 to DDR4 RAM can significantly improve the speed.
Additionally, optimizing the computer's memory settings in the BIOS or UEFI can also help increase the speed of SDRAM without relying on changes to the system clock.
