What is the bus clock MHz of DDR?
DDR SDRAM operating with a 100 MHz clock is called DDR-200 (after its 200 MT/s data transfer rate), and a 64-bit (8-byte) wide DIMM operated at that data rate is called PC-1600, after its 1600 MB/s peak (theoretical) bandwidth. DDR SDRAM uses double-data-rate signalling only on the data lines.
What is the bus speed of DDR3 RAM?
The clock speed of DDR3 vary from 800 MHz to 2133 MHz, where 2133 MHz is the its peak in some cases, generally clock speed is vary between 1600 to 1800 MHz.
What is the peak transfer rate of a DDR3/1600 module?
12.8GB/sec
DDR3-1600 memory has a module classification of PC3-12800, which effectively means the peak data rate of the module is 12.8GB/sec (see table).
What is the transfer rate of DDR3-1600?
12800 MB/s
DDR3 speeds
| Friendly name | Industry name | Peak Transfer Rate |
|---|---|---|
| DDR3-800 | PC3-6400 | 6400 MB/s |
| DDR3-1066 | PC3-8500 | 8533 MB/s |
| DDR3-1333 | PC3-10600 | 10667 MB/s |
| DDR3-1600 | PC3-12800 | 12800 MB/s |
What is bus clock rate in RAM?
A bus cycle occurs every time data travels from memory to the CPU. For example, a 100-MHz 32-bit bus is theoretically capable of sending 4 bytes (32 bits divided by 8 = 4 bytes) of data to the CPU 100 million times per second, while a 66-MHz 16-bit bus can send 2 bytes of data 66 million times per second.

How is memory clock and I / O bus clock different?
I/O bus clock is always half of bus data rate. example: DDR2-800: bus data rate is 800 MT/s, IO clock is 400 MHz. Memory clock is the clock which sync memory controller: DDR1: 1/2 of bus data rate, because of 2n-prefetch
Which is the correct memory speed DDR3 or 1333?
The specs posted to the Sony website are incorrect in that it states the Type/Speed is DDR3/1333MHz. The “1333” speed reference pertains to MT/s (data rate) not MHz (I/O bus clock). Sony needs to correct their website specs for this product.
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 speed of a DDR memory module?
A DDR memory module transfers data at 64-bits at a time which equates to 8-bytes at a time. Therefore we can work out the speed of the memory. DDR-200 runs at 200MHz which works out at 200 x (64/8) = 1600MB/s (megabytes per second).
