What is the maximum transfer rate of DDR3 SDRAM?

What is the maximum transfer rate of DDR3 SDRAM?

With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits in a byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s.

What’s the difference between DDR2 and DDR3 DIMMs?

DDR3 dual-inline memory modules (DIMMs) have 240 pins and are electrically incompatible with DDR2. A key notch—located differently in DDR2 and DDR3 DIMMs—prevents accidentally interchanging them. Not only are they keyed differently, but DDR2 has rounded notches on the side and the DDR3 modules have square notches on the side.

What’s the maximum memory size for DDR3 memory?

The DDR3 standard permits DRAM chip capacities of up to 8 gibibits, and up to four ranks of 64 bits each for a total maximum of 16 GiB per DDR3 DIMM. Because of a hardware limitation not fixed until Ivy Bridge-E in 2013, most older Intel CPUs only support up to 4- gibibit chips for 8 GiB DIMMs…

What’s the difference between DDR3L and PC3L memory?

The DDR3L (DDR3 Low Voltage) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices. The DDR3L standard is 1.35 V and has the label PC3L for its modules.

How is the bandwidth of DDR3 memory calculated?

Bandwidth is calculated by taking transfers per second and multiplying by eight. This is because DDR3 memory modules transfer data on a bus that is 64 data bits wide, and since a byte comprises 8 bits, this equates to 8 bytes of data per transfer.

What’s the difference between DDR3 and DDR2 SDRAM?

DDR3 SDRAM. DDR3 is a DRAM interface specification. The actual DRAM arrays that store the data are similar to earlier types, with similar performance. The primary benefit of DDR3 SDRAM over its immediate predecessor, DDR2 SDRAM, is its ability to transfer data at twice the rate (eight times the speed of its internal memory arrays),…

Why is DDR3 SDRAM not backward compatible with earlier memory?

DDR3 SDRAM is neither forward nor backward compatible with any earlier type of random-access memory (RAM) because of different signaling voltages, timings, and other factors. DDR3 is a DRAM interface specification. The actual DRAM arrays that store the data are similar to earlier types, with similar performance. See More…

What’s the maximum memory size for DDR3 memory?

The DDR3 standard permits DRAM chip capacities of up to 8 gigabits (Gbit), and up to four ranks of 64 bits each for a total maximum of 16 gigabytes (GB) per DDR3 DIMM.

What’s the correct name for a DDR3 memory module?

Alternative naming: DDR3 modules are often incorrectly labeled with the prefix PC (instead of PC3), for marketing reasons, followed by the data-rate. Under this convention PC3-10600 is listed as PC1333.
