This rate is normally specified relative to the front-side bus clock. (DRAM Clock) Specifies the clock speed of the memory bus. (Active to Precharge Delay, Precharge Wait State, Row Active Delay, Row Precharge Delay) Delay that results when two different rows in a memory chip are addressed one after another. Setting this value to two clock cycles can enhance performance by up to four percent. (RAS to CAS Delay, Active to CMD) Number of clock cycles that pass between the row address being determined and the column address being sent out. (RAS Precharge, Precharge to active) Number of clock cycles needed to precharge the circuits so that the row address can be determined.
How to make computer faster through bios full#
If your memory banks are full to capacity, you will have to raise this rate to two, resulting in a considerable drop in performance. (Command Rate, MA 1T/2T Select) Number of clock cycles needed to address the memory module and the memory chip with the desired data zone. Windows 7, 8, and 10 defrag your hard drive automatically. Defragmenting will organize your data and free up space so your computer can access data faster. The memory manufacturer lists the best possible setting as the CL rating. When data is fragmented, your computer must search for the fragments of files that could be spread all over your hard drive. (CAS Latency Time, CAS Timing Delay) The number of clock cycles that pass from the column being addressed to the data arriving in the output register.
That is equal to 64 Bytes, or eight data packets. Ideally, one transmission will fill one memory row on the L2 cache found in modern Pentium 4 and Athlon XP CPUs. The burst length specifies how many data blocks are sent in one transmission cycle.
