What is the DDR rating for PC3200?
3.2GBps
Also known as “DDR-400.” A rating for the performance of DDR SDRAM chips. The “3200” portion represents the transfer rate in MBps (megabytes per second), so with PC3200 RAM, the chips are rated for 3.2GBps (gigabyte per second) speeds.
What is the difference between DDR 400 and PC3200?
DDR400 means DDR RAM that runs at 400Mhz (2 x 200Mhz). PC3200 means 3.2GB/s, the transfer speed.
What is PC3200 memory?
PC3200 is DDR SDRAM designed to operate at 200 MHz using DDR-400 chips with a bandwidth of 3,200 MB/s. Because PC3200 memory transfers data on both the rising and falling clock edges, its effective clock rate is 400 MHz.
What is the total bandwidth of a DDR 333 Sdram?
2666 MB/sec
Note that even though modules using DDR333 chips have a bandwidth of 2666 MB/sec, the modules are called PC2700 instead.
What is the clock speed rating for DDR RAM with a DDR 200 speed rating and PC 1600 PC speed rating?
Ram Chart
| Module Type | Chip Type | Clock Speed |
|---|---|---|
| PC-1600 DDR SDRAM | DDR-200 | 100 MHz |
| PC-2100 DDR SDRAM | DDR-266 | 133 MHz |
| PC-2700 DDR SDRAM | DDR-333 | 166 MHz |
| PC-3200 DDR SDRAM | DDR-400 | 200 MHz |
What is the bandwidth of DDR4?
17 GB/s
What are the data transfer rates for DDR, DDR2, DDR3 and DDR4?
| RAM Type | Speed | Peak Transfer Rate* |
|---|---|---|
| DDR4 | 2133 | 17 GB/s |
| 2400 | 19.2 GB/s | |
| 2666 | 21.3 GB/s | |

| Voltage | 1,5V | 1,2V |
| Low Voltage Standard | Yes (DDR3L at 1.35V) | Anticipated at 1.05V |
| Internal Banks | 8 | 16 |
What is Sdram in laptop?
SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.
What is the total bandwidth of a DDR2 533 module?
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.
How is DDR memory bandwidth calculated?
The theoretical maximum memory bandwidth for Intel Core X-Series Processors can be calculated by multiplying the memory frequency (one half since double data rate x 2), multiplied by the number of the bytes of width, and multiplied by the number of the channels supported for the processor.
How fast is 3200mhz RAM?
25.6 GB/s
What is the effective clock rate of PC3200 memory?
Because PC3200 memory transfers data on both the rising and falling clock edges, its effective clock rate is 400 MHz. 1 GB PC3200 non-ECC modules are usually made with 16 512 Mbit chips, 8 on each side (512 Mbits × 16 chips) / (8 bits (per byte)) = 1,024 MB.
What’s the difference between DDR SDRAM and PC-1600?
The package sizes in which DDR SDRAM is manufactured are also standardized by JEDEC. There is no architectural difference between DDR SDRAM designed for different clock frequencies, for example, PC-1600, designed to run at 100 MHz, and PC-2100, designed to run at 133 MHz.
What’s the maximum transfer rate of DDR SDRAM?
Thus, with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s.
What are the characteristics of a DDR memory module?
Module characteristics. A module of any particular size can therefore be assembled either from 32 small chips (36 for ECC memory), or 16 (18) or 8 (9) bigger ones. DDR memory bus width per channel is 64 bits (72 for ECC memory). Total module bit width is a product of bits per chip and number of chips.
