The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
These adjustments provide the two common methods of overclocking and underclocking a computer, perhaps combined with some adjustment of CPU or memory voltages (changing oscillator crystals occurs only rarely); note that careless overclocking can cause damage to a CPU or other component due to overheating or even voltage breakdown.
In the late 1980s IBM invented DDR SDRAM, they built a dual-edge clocking RAM and presented their results at the International Solid-State Circuits Convention in 1990. [ 6 ] [ 7 ] Samsung released the first commercial DDR SDRAM chip (64 Mbit ) in June 1998, [ 3 ] followed soon after by Hyundai Electronics (now SK Hynix ) the same year. [ 8 ]
Machine checks are a hardware problem, not a software problem. They are often the result of overclocking or overheating. In some cases, the CPU will shut itself off once passing a thermal limit to avoid permanent damage. But they can also be caused by bus errors introduced by other failing components, like memory or I/O devices.
In order to prevent damage by accidental insertion of the wrong memory type, DDR5 UDIMMs and (L)RDIMMs are not mechanically compatible. Additionally, DDR5 DIMMs are supplied with management interface power at 3.3 V, [ 19 ] [ 20 ] and use on-board circuitry (a power management integrated circuit [ 21 ] and associated passive components ) to ...
Memory timings or RAM timings describe the timing information of a memory module or the onboard LPDDRx. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands. Executing commands too quickly will result in data corruption and results in system instability.
Both dynamic voltage scaling and dynamic frequency scaling can be used to prevent computer system overheating, which can result in program or operating system crashes, and possibly hardware damage. Reducing the voltage supplied to the CPU below the manufacturer's recommended minimum setting can result in system instability.
A memory leak can cause an increase in memory usage and performance run-time, and can negatively impact the user experience. [4] Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to ...
