How to check RAM type (DDR, DDR2 or DDR3) in Windows?

Well, we’ve come a long way, from command-based computers to having touch-interface enabled systems. The same goes for other supportive hardware on our systems as well.

Hardware pieces like the Graphic card, USB ports, or even the  RAM have held the hand of evolution every step of the way. That’s what gave birth to DDR DDR2 and DDR3 types of RAM in the first place.

So before getting to the bottom of How to Detect the Type of RAM in a PC, let’s have a basic insight into what RAM types exactly exist on the planet.

What are DDR, DDR2 and DDR3 RAM Types?

DDR:- (Double Data RAM )

One of the earliest kinds of RAMs to see the light of day was the DDR RAMs. Considering we’re more friendly with the DDR3 generations these days, there isn’t a lot I can sing in praise of these ancient types.

They consumed a lot more power than the DDR2 RAMs, demanding a voltage of almost 2.5v compared to only 1.8v with the DDR2 RAMs.

They had a speed of around 200-800MHz and had 2-bits prefetch buffers, with a maximum reading latency of 3 clock cycles, compare that to the 9-clock cycle reading latency of the DDR2 RAMs and it won’t be hard to imagine why the DDRs went out of business.

DDR2:- (Double Data RAM 2)

The Internal clocks of the DDR2 RAMs run at half the speed of the data bus, meaning it has twice the speed of the original DDR RAMs, the improved bus signal helps us achieve that.

Also, these have a theoretical typical latency of around 5 compared to only 3 of the DDR RAMs. But obviously that’s lower than the typical latency of the DDR3 RAMs.

Although the number of pins both for the DDR2 and DDR3 RAMs is the same, that’s 240!

DDR3:- (Double Data RAM 3)

The primary benefit it offers us is lower power consumption (lowest in comparison to the other two types), as much as 40% lower! Also, it’s comparatively faster, with the bus clock running at 533-800 Mhz and with data rates between 1066-1600MT/s!

There are a bunch of other technical terms, but in the simplest possible words, all I can say is, DDR3 is the fastest RAM type available today.

Worry not we will be getting down to How to check RAM speed, but before that let’s spend just a couple more minutes understanding the difference between DDR3 and DDR2 RAM types.

Primary Difference Between DDR3 and DDR2 RAM Types:-

  • The Prefetch buffer for DDR3 RAM types is the 8-bit deep buffer while the DDR2 operates on a 4-bit prefetch buffer.
  • The data transfer rate with DDR 3 RAMs is an impressive 800-1600MHz while that with the DDR2 RAM types is only around 400-800MHz
  • The DDR2 RAMs use a 200-400MHz I/O clock for data transfer, while the DDR3 RAMs make use of the more effective, 100-200mHz I/O clocks.
  • As mentioned earlier, the power consumption with DDR3 RAMs is considerably lower compared to DDR2 RAMs, as much as 40% lower to be specific, and this comes in handy and as a great marketing edge when it comes to power specific devices like Laptops.
  • If you’re a gaming geek you might be familiar with the different types of Graphic Cards. Well, DDR3 RAMs are preferable while processing graphics because those cards need faster frame rates which isn’t the case with DDR2 RAMs.

Cons:-

Not all the “grass is greener on the other side”, and the same applies to the different types of RAMs as well.

  • DDR3 RAMs are a tad bit more expensive compared to DDR2 RAMs. (It isn’t exactly a negative factor, but it counts!)
  • The CAS Latency for DDR3 RAMs is higher compared to DDR2 RAMs.

How to check RAM type (DDR, DDR2 or DDR3) in Windows?

So finally we’re down to the section you’ve been waiting for. In this final section of this article, I’ll be explaining how to check RAM type in windows 7, (the process is more or less similar to every other Windows Operating system.) plain and simple.

Unfortunately, there’s no in-built option or tool which tells you the RAM type on Windows, so you’ll need the help of third-party software like CPU-Z.  (It’s a lightweight program, less than 1MB in size, and is free!)

Go to the link above, choose your operating system and click on download.

Once you’ve downloaded it, install it like any other Windows program.

How to check RAM type (DDR, DDR2 or DDR3) in Windows

After it’s successfully installed, just run it from its desktop icon or the start menu.

And then click on “Memory”. It will get you all the details you need to unveil regarding your RAM.

In fact, apart from the RAM type, it gets you other advanced details as well including:-

  • CAS Latency
  • RAS Delay
  • Cycle Time etc.

And just in case you might want to peep through the other options on the screen, feel free to do so.

In fact, if you click on the CPU option, it gets you a plethora of information which includes Bus type, technology, code name, Clock data, core data and what not!

Other tabs like the MainBoard can be used to access information related to the Motherboard of your system.

And the best part is, there’s even a “Bench” tab, which lets you benchmark your system, either individually as a single-thread or as a multi-thread machine.

Final Words:-

So that was all I had on How to check RAM type (DDR, DDR2 or DDR3) in Windows folks. I hope this piece helped, in fact, I tried my best to make sure you get not only the RAM types but also other information that you might need at a later time.

You can use CPU-Z to access just about any other kind of CPU information related to your system. And it’s not an “authoritative” tool, rather a reflective one, so feel free to play around because there’s not a lot you can mess up with this one.
