Can We Use Ddr2 Ram In Ddr3 Slot

Sep 17, 2013 You cannot change DDR2 modules for DDR3, they are different technologies and the modules are not compatible with each other. According to Crucial you can upgrade your laptop either to 4GB or to 8GB, depending on the exact model. All the newer PC's use DDR or DDR2 (even DDR3) memory. Try to find out how many pins the memory slots use. I believe that SDRAM is 168pins and DDR/DDR2 is 240pin. Due to the different pin design of DDR2 and DDR3, it will be physically impossible to put a DDR2 stick into a DDR3 slot. You will need to have DDR3 RAM. When you buy it, be sure that it runs at 1.65V or less; that's RAM designed for the X58 and P55 chipsets. Anything over running in the 1.7-1.9V range was for Nvidia's 780i chipset.

DDR2 vs DDR3 RAM - What's the difference between DDR2 and DDR3 memory? How do you tell them apart? Can you use DDR3 RAM in a DDR2 socket? Get the full answers right here.

The RAM found in most modern desktop and laptop computers is DDR3 RAM (DDR3 is short for Double Data Rate Type 3). To be more precise, its full technical name is DDR3 SDRAM.

If your computer was built in 2008 or earlier, then chances are that it has the older DDR2 RAM instead.

At buildcomputers.net, we don't take chances or make guesses.. so let's learn what are the differences between DDR3 vs DDR2 RAM and how to tell them apart.

How to Tell If You Have a DDR2 or DDR3 RAM Module

Hp pavilion x360 14 ram slot. In terms of physical appearance, DDR2 vs DDR3 RAM looks largely similar. They are of the same length (~13.3 cm or 5.25 in) and have the same number of pins (240):

Here's the trick to tell them apart: Look at their notch positions (circled in yellow above).

As you can see from the image below, the DDR2 notch is located near the middle of the RAM stick while the DDR3 notch is positioned nearer to the left side. If you want to be more precise,

• DDR2: distance between left side of RAM stick and notch = 7.1 cm (2.8 in)
• DDR3: distance between left side of RAM stick and notch = 5.4 cm (2.1 in)

This difference in notch position is also why you can't use DDR3 RAM in a DDR2 system or install DDR2 RAM into a DDR3 slot (even though they have the same number of pins).

In short, DDR2 and DDR3 RAM are not compatible with each other: If your motherboard has DDR2 RAM slots, then you can only use DDR2 RAM. The same applies to DDR3 RAM.

What's the Difference between DDR2 and DDR3 RAM?

From the DDR2 vs DDR3 table above, we can see that DDR3 RAM offers better performance while consuming less power.

The difference in clock speed and max transfer rate numbers look impressive on paper, but DDR3 RAM is in fact just 2 to 10% faster than DDR2 RAM for most real-world applications (depending on your hardware specification and usage).

DDR3 RAM consumes less power and produces less heat than DDR2 RAM at the same clock speed (e.g. DDR3 vs DDR2 RAM that is both running at 1,066 MHz). However there is a catch: RAM with higher clock speeds have higher power consumption so DDR3 RAM running at 2,133 MHz will still drain more power than DDR2 RAM at 1,066 MHz.
