What is the difference between DDR3 and SDRAM?

DDR2 533 and DDR2 800 memory types are on the market. DDR3 SDRAM(Double Data Rate Three SDRAM): DDR3 memory reduces 40% power consumption compared to current DDR2 modules, allowing for lower operating currents and voltages (1.5 V, compared to DDR2’s 1.8 V or DDR’s 2.5 V). The transfer rate of DDR3 is 800~1600 MT/s.

How many pins does DDR3 SO DIMM have?

204 pins
SO DIMM sockets are designed for the latest DDR4, as well as previous versions DDR3, DDR2, DDR, and SDRAM memory modules. For DDR1 and DDR2 SO DIMM sockets, the pin count is 200 pins; for DDR3 SO DIMM sockets, the pin count is 204 pins; for DDR4 SO DIMM sockets, the pin count is 260 pins.

Which is better SDRAM or DDR?

The main difference between SDRAM and DDR memory is the doubled speed: DDR can transfer data at roughly twice the speed of SDRAM. PC133 SDRAM runs at 133 MHz, while 133 MHz DDR effectively runs at 133 MHz x 2 = 266 Mhz.

What is VTT termination?

VTT is a memory bus termination voltage equaling VDDQ/2. To place VTT in perspective, it is necessary to understand how system voltages are related.

Is SDRAM compatible with DIMM?

Honorable. Yes, SDRAM is the same thing as DIMM basically.

What is the difference between DIMM and SO-DIMM?

A Registered DIMM is a memory module designed for network servers and high end workstations. A SODIMM (Small Outline Dual In-line Memory Module) is a memory module with a smaller outline and thickness than standard DIMM modules and designed primarily for notebook computers.

How many pins does a DIMM have?

On the bottom edge of 168-pin DIMMs there are two notches, and the location of each notch determines a particular feature of the module.

What is termination in DDR?

DDR termination regulators achieve power conservation by rapidly dropping or increasing current so that the output termination voltage (VTT) would be half of the supply voltage (VDDQ). This results in reduced power dissipation and higher efficiency.

What is VTT in DDR3?

The Vtt Power Supply provides the proper voltage to the termination resistors on the Command, Address, and Control signals on the DIMM. This voltage is set at Vdd/2, which is nominally 0.75V for DDR3 and 0.6V for DDR4.

Is DIMM and SDRAM the same?

DIMM is a printed circuit board with mounted DRAM or SDRAM integrated circuits. SDRAM is Synchronous DRAM that runs at significantly higher clock speeds. Cooling. As DIMM chip density increased to improve performance, higher clock speeds generated more heat.

Can I use DDR3 RAM in DIMM slot?

All DDR3 sold for PC’s uses 240 pin DIMM’s (or 204 pin SO-DIMM’s for laptops. So SDRAM and DIMM are referring to slightly different things. Anyway the simple answer is yes DDR3 SDRAM will work with your motherboard, and in fact you already have DDR3 SDRAM installed.
