A memory divider is a ratio which is used to determine the operating clock frequency of computer memory in accordance with front side bus (FSB) frequency, if the memory system is dependent on FSB clock speed. Along with memory latency timings, memory dividers are extensively used in overclocking memory subsystems to find stable, working memory ...
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.
Overclocking is the process of forcing your computer to run faster than it's intended to go, which can help you run advanced programs on an older PC.
When translating memory timings into actual latency, timings are in units of clock cycles, which for double data rate memory is half the speed of the commonly quoted transfer rate. Without knowing the clock frequency it is impossible to state if one set of timings is "faster" than another.
For instance, under a 1,066MHz FSB, the only choices regarding memory speed in the MRC are DDR2-667 and DDR2-800. We have to provide additional choices. For people who want higher memory frequency, we used the setting of 800MHz FSB:DDR2-800 in MRC, but overclocked it to work with a 1,066MHz FSB, so we could implement support for DDR2-1066.
In contrast with standard SDRAM, used in stationary devices and laptops and usually connected over a 64-bit wide memory bus, LPDDR also permits 16- or 32-bit wide channels. [2] The "E" and "X" versions mark enhanced versions of the specifications. They formalize overclocking the memory array by usually 33%.
However, other methods exist of producing inaccurate or fake time results, raising questions about the program's future as an overclocking benchmark. Super PI utilizes x87 floating point instructions which are supported on all x86 and x86-64 processors, current versions which also support the lower precision Streaming SIMD Extensions vector ...
Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017. [9] [10] On November 15, 2018, SK Hynix announced completion of its first DDR5 RAM chip; running at 5.2 GT/s at 1.1 V. [11] In February 2019, SK Hynix announced a 6.4 GT/s chip, the highest speed specified by the preliminary DDR5 standard. [12]
