What PC2-4200?
DDR2 PC2-4200 (commonly referred to as DDR2-533) memory is DDR2 designed for use in systems with a 266MHz front-side bus (providing a 533MT/s data transfer rate). The “4200” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 4200MB/s, or 4.2GB/s.
What is the full form of Sdram?
SDRAM (Synchronous Dynamic Random Access Memory): “Synchronous” tells about the behaviour of the DRAM type.
What was the original clock rate for DDR2?
DDR2 was officially introduced in the second quarter of 2003 at two initial clock rates: 200 MHz (referred to as PC2-3200) and 266 MHz (PC2-4200). Both performed worse than the original DDR specification due to higher latency, which made total access times longer.
When did DDR2 SDRAM come to the market?
DDR2 was officially introduced in the second quarter of 2003 at two initial clock rates: 200 MHz (referred to as PC2-3200) and 266 MHz (PC2-4200).
What kind of memory interface is DDR2 SDRAM?
DDR2 SDRAM is a double data rate synchronous dynamic random-access memory interface.
What’s the difference between DDR and DDR2 DIMMs?
The notch on DDR2 DIMMs is in a different position from DDR DIMMs, and the pin density is higher than DDR DIMMs in desktops. DDR2 is a 240-pin module, DDR is a 184-pin module. Notebooks have 200-pin SO-DIMMs for DDR and DDR2; however, the notch on DDR2 modules is in a slightly different position than on DDR modules.
