The BIOS on a PC may allow the user to manually make timing adjustments in an effort to increase performance (with possible risk of decreased stability) or, in some cases, to increase stability (by using suggested timings). [clarification needed] DDR5 introduced support for FGR (fine granular refresh), with its own tRFC2 and tRFC4 timings. [1]
None of its successors are forward or backward compatible with DDR1 SDRAM, meaning DDR2, DDR3, DDR4 and DDR5 memory modules will not work on DDR1-equipped motherboards, and vice versa. Compared to single data rate ( SDR ) SDRAM, the DDR SDRAM interface makes higher transfer rates possible through more strict control of the timing of the ...
Double Data Rate 5 Synchronous Dynamic Random-Access Memory (DDR5 SDRAM) is a type of synchronous dynamic random-access memory. Compared to its predecessor DDR4 SDRAM , DDR5 was planned to reduce power consumption, while doubling bandwidth . [ 5 ]
The MRC is part of reference BIOS code, which relates to memory initialization in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced ...

This was generally described as "5-2-2-2" timing, as bursts of four reads within a page were common. When describing synchronous memory, timing is described by clock cycle counts separated by hyphens. These numbers represent t CL-t RCD-t RP-t RAS in multiples of the DRAM clock cycle time.
So, for example, for a burst length of four, and a requested column address of five, the words would be accessed in the order 5-6-7-4. If the burst length were eight, the access order would be 5-6-7-0-1-2-3-4. This is done by adding a counter to the column address, and ignoring carries past the burst length.
Column address strobe latency, also called CAS latency or CL, is the delay in clock cycles between the READ command and the moment data is available. [1] [2] In asynchronous DRAM, the interval is specified in nanoseconds (absolute time). [3]
