Ddr2 and ddr3 slot difference

By author

Difference is the location of notch. DDR2 notch is centrally located while DDR3 notch is a little offset from center. You can look at the notch position in RAM slot on your computer’s motherboard to find out what type of RAM it will accept. DDR3 uses less power than DDR2. DDR3 uses 1.5V as compared to DDR2 that uses 1.8V.

This is a video giving some basic differences between the new gen DDR3 memory modules and the previous gen DDR2 memory modules. Difference Between DDR3 and DDR3L | DDR3 vs DDR3L DDR3 vs DDR3L. The main difference between DDR3 and DDR3L is in the voltage specification. Voltage specification for DDR3 is 1.5V, but the voltage for DDR3L is less, which is 1.35V. The letter L in DDR3L refers to low voltage standard. As DDR3L is a special type of DDR3 all other specifications except the voltage remains the same. What's the Difference Between DDR2 and DDR3? | Crucial.com DDR3 is not backwards compatible with DDR2. While both types of modules have similar numbers of pins, the notches in the PCB are in different locations. In other words, a DDR3 module cannot be placed in a DDR2 memory socket, and vice-versa. DDR3 uses less power. DDR3 modules run on 1.5V compared to the 1.8V that DDR2 modules require. What is the difference between DDR2 and DDR3? - UFASK Main differences between DDR2 and DDR3 DDR2 memory operates at frequencies ranging from 400 to 800 Mhz, generating data rates up to 800 Mbps. In contrast, DDR3 operates from 800 to 1600 Mhz with a data transmission rate of up to 1600 Mbps.

DDR2 "JEDEC standard" memory typically stops at around 800MHz whereas the introductory speeds of DDR3 when it was released in 2007 started at 800MHz. Current DDR3 memory runs up to 1866MHz and performance DDR3 modules (Crucial Ballistix) are capable of running at speeds greater than 2100MHz.

In contrast, DDR3 operates from 800 to 1600 Mhz with a data transmission rate of up to 1600 Mbps. DDR2 consumes more power because it provides 1.8 volts.

DDR3 vs DDR4 is the hottest topic these and many confused between DDR3 and DDR4. We will help you figure out which one you need to buy,

Basically it is a lower power lower heat version of memory based on the DDR2 specification. GDDR3 also features higher bandwidth than traditional DDR2. so the difference between GDDR3 and DDR3 is that GDDR3 is memory designed for use in graphics cards and is based on DDR2. DDR3 is the successor to DDR2 and is used for computer ram.

Best Answer: DDR3 is a standard, DDR2 is a different standard, DDR is a different standard. You cannot mix and match them. And, you can only use the type of RAM in the computer that the motherboard was designed for.

DDR1 is 184 pin, while DDR2 and DDR3 are both 240 pin, so some motherboards support both DDR2 and DDR3. If the speed is not supported by the motherboard, it will revert to the highest supported speed. All RAM will run at the speed of the slowest module. In theory, it should work; I wouldn't count on it. What are the differences between ddr1 ddr2 and ddr3? Answer No. DDR3 is not backward compatible with DDR2 and DDR. e.g. DDR3 has 1.5V power, DDR2 needs 1.8V and DDR needs 2.5V power. In terms of standard motherboard slots also the notch or the key ... Difference between ddr ddr2 and ddr3 - answers.com The DDR3 has 240 pins just like the DDR2, however, they will not be compatible, you will not be able to put a DDR3 into a DDR2 slot. The knotch on the stick of RAM is in a different location so it ...
