DDR3 Desktop RAM
DDR4 Desktop RAM
DDR5 Desktop RAM
Different types of Desktop Memory
- SDRAM stands for Synchronous DRAM- it started out running at a speed of 66MHz but can be upgraded to 180 MHz.
- DDR stands for Double Data Rate memory- the system doubles the rate of data transfer of the regular SDRAM by moving data through a clock cycle. The fact that it is doubled means that if it is rated 333MHz, it is actually operating at 166MHz multiplied by two. DDR Ram consists of DDR2, DDR3, DDR4, and soon DDR5 all which indicate the speed capacity.
- Rambus SDRAM is the last common type of desktop RAM that is available. It is common in what we call the Pentium memory range of computers and is the most recommended memory types for the new computer models.
What is the difference between desktop memory and laptop memory?
What distinguishes laptop memory from desktop memory is the form factor Form factor is a memory’s physical size and its pin arrangement. Most desktop manufacturers use DIMM. A full-size DIMM has 100, 168, 184, or 240 pins and is usually 4.5 to five inches in length. Most laptop manufacturers use SO DIMM (Small Outline DIMM). A SO DIMM has 72, 100, 144, or 200 pins and is smaller — 2.5 to 3 inches. There is also SO RIMM, which is similar to SO DIMM, but like DIMM/RIMM has a different pin count.
What does DDR stand for?
DDR is the abbreviation for Double Data Rate. DDR3, and DDR4 memory are based on the design predecessor RAM SDRAM which stands for Synchronous RAM. This means that they synchronize things using a clock signal. Memories from the DDR category transfer two chunks of data in one cycle.
