DQS = data strobe. When data is read from DRAM using the DQ pins, DQS is asserted so that memory controller can use that to read data. When memory controller writes to DRAM, it asserts DQS when DQ pins have the data to be written.

The DDR3 has two pairs of DQS in per data lane for optimal termination values. IT is also for signal topology and the possible swapping of the DDR3's memory side pin.Ê

DDR3 means that the memory is double data rate type three. SDRAM indicates that it is synchronous dynamic RAM. the 1066 MHz refers to the clock frequency that it transfers data at.



It represents DDR3 SDRAM with Data Rate of 1600 MT\s with 200 Mhz (1600/8) memory clock.


DDR3 itself, stands for double data rate (revision 3). DDR3 commonly precedes "memory" or "RAM." DDR3 SDRAM is used in most modern computers or laptops, although DDR4 RAM will make its debut in the next year.

The Apple MacBook has a 2.0GHz or 2.4GHz Intel Core 2 Duo processor with a 3MB on-chip shared L2 cache, a 1066MHz frontside bus, and 2GB (two 1GB SO-DIMMs) of 1066MHz DDR3 SDRAM; and uses the NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory.


DDR3 SDRAM stands for double data rate type three synchronous dynamic random access memory. It is used at the tempory memory a computer needs to operate. It is a faster version of the DDR2 RAM.


Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color-coded on the motherboard.


Types of DIMMs are DDR3 and DDR2 that have 240 pins, DDR DIMMs with 184 pins and SDRAM DIMMs with 168 pins.


The 184-pin DIMM configuration was used for DDR SDRAM. It is identified by sharing the larger contact sizes with the earlier SDRAM, but having only one cut out instead of two. Later DDR2 and DDR3 have much smaller contacts.


No. SDRAM and DDR SDRAM are not compatible with each other.


DDR3 SDRAM. This type of memory is the only one capable of triple-channeling, hence the three yellow slots. :)


No, DDR2 is quite slower than DDR3. DDR4 was released very recently. DDR4 is currently the fasted SDRAM available.


Most current motherboards are using DDR3 SDRAM, although new higher-performing motherboards are starting to appear which use DDR4.
