Memory Lane: DDR SDRAM

As some of you may recall, before branching out into power supplies, coolers, fans, cases, and gaming peripherals, CORSAIR was primarily known for high performance memory products! We’ve got a long history with DRAM and today we’d like to take a brief look back at the original DDR, a time when Athlon and Pentium processors were king.

What is DDR?

No, it’s not a rhythm game. DDR or Double Data Rate SDRAM brought about a significant change in how memory works in a computer. Those with keen eyes might notice it in the name, double data rate, but what does that mean exactly?

CORSAIR XMS Platinum Series DDR Memory

Previous generations of SDRAM could only perform one read or write command per clock cycle, DDR SDRAM on the other hand, could perform two commands per clock cycle, it’s as simple as that!

Additional Improvements

Additional improvements with the first generation of DDR were increased densities of up to 1 GB and speeds hitting over 200MHz, providing an effective speed of over 400MHz when you account for double data rate!

Dual Channel Comes to Market

One other evolution of DRAM that came with DDR memory was the concept of running memory in dual channel. This meant that your processor could send commands to two modules at once, further increasing bandwidth! Dual channel memory would be a continuing trend on mainstream platforms to this day.

CORSAIR XMS Pro Series Twin X

To make it easy to ensure that systems at the time could take advantage of dual channel memory configurations, CORSAIR introduced its first twin pack of matched memory modules with the XMS Twin X so that you’d be guaranteed to have two modules with the same ICs and rated for the same frequencies (we still do this today for all memory kits that include 2, 4, and even 8 modules for quad channel)!

A Glimpse at the Future

This was also a time when windowed side panels were just starting to come into fashion, so we released our first LED memory modules with the XMS PRO series that featured activity LEDs along the top bar so you could check your memory utilization at a glance.

We followed up XMS Pro Series with XMS XPERT, which took the activity LEDs a step further with a fully programmable digital read out that let you check info like frequency, temperature, and voltage in real time!

Closing Thoughts

DDR SDRAM was a big deal for computing and paved the way for what was to come in further generations of DDR memory as faster processors with a growing number of cores were on the horizon.

CORSAIR 4000, 5000, and 7000 Series PC Cases

The CORSAIR 7000 Series of full-tower cases is our latest addition to our new case lineup that started with the CORSAIR 4000 Series last year and 5000 Series earlier this year. Today we’ll take a look at the core features that these cases share as well as what makes them unique to help you decide which chassis is the right one for your next build! 

The Details

For convenience, we’ve put together the following comparison charts for reference:

X-variant case comparisons
D-variant case comparisons

It’s All in the Name

The 4000, 5000, and 7000 Series cases support motherboard form-factors of mini-ITX up to E-ATX, and as you go up the stack, the more internal volume you’ll have available, with the 4000 Series being the most compact and 7000 Series being the largest. More internal volume allows for more fans, radiators, and other accessories to be installed.

Beyond the series number, the letter at the end of the name helps to denote the feature set a case is equipped with. For example, an “X” case focuses more on showcasing your components and comes equipped with additional tempered glass panels (two on 4000X, four on 5000X, and three on 7000X cases) when compared to a “D” case which feature solid/perforated steel front panels with a focus more on minimalism or performance (as seen on AIRFLOW versions) while retaining a large tempered glass side panel. 

Keeping Your Build Cool

CORSAIR SP RGB Elite AirGuide Fans

Since the 4000X, 5000X and 7000X lines offer tempered glass front panels, they also come with CORSAIR SP RGB Elite AirGuide fans in the box whereas the 4000D, 5000D, and 7000D lines will come with non-RGB AirGuide fans. The 7000 Series comes equipped with 140mm fans and the 4000/5000 Series come with 120mm fans. In the larger 5000 and 7000 Series cases, you’ll also find a PWM repeater to help manage cooling.

When it comes to RGB, the 4000X and 5000X cases include a CORSAIR Lighting Node CORE to manage fan lighting and the 7000X comes with a COMMANDER CORE XT that offers a complete package of lighting and PWM fan control. Both the Lighting Node CORE and COMMANDER CORE XT connect to your motherboard via an internal USB 2.0 header and are managed using CORSAIR iCUE

CORSAIR XR5 series radiators for custom water cooling

When it comes to water cooling, 4000 and 5000 series cases can support up to 360mm radiators from either an AIO (all-in-one) liquid CPU cooler or custom water cooling components like our CORSAIR Hydro X Series . 7000 series cases on the other hand can support up to 420mm and 480mm radiators for some serious cooling!

Keeping Your Build Tidy

When it comes to PC building, it goes without saying that cable management is very important and we want to take this opportunity to highlight the benefits of the RapidRoute Cable Management System that is part of the core feature set in the 4000, 5000, and 7000 Series cases.

Cable management is probably the most overlooked process of PC building, especially for beginners. With our new case family, cable management couldn’t be easier for a new system builder, as we’ve designed the 4000, 5000, and 7000 Series cases to have more physical space available behind the rear side panel and include cable raceways and straps to make it quick and easy to organize your cable clutter!

Imagine the Possibilities

This new case lineup is our best yet and we can’t wait to see what builds you’ll make with them! For those still deciding which case to go with, here are some final notes that may help:

4000 Series – The 4000 Series is a great start to a new build, fitting the standard mid-tower look while providing a lot of features that make it easy to build in and provide excellent cooling to your components. 

5000 Series – The 5000 Series takes the winning formula of the 4000 Series and packs it into a larger mid-tower with expanded cooling options and room for larger components and accessories. 

7000 Series – The 7000 Series expands the cable management and performance concepts to a full-tower providing all the fan/cooler mounting and internal space you need to build your next masterpiece! 

And to see what a fully custom water-cooled build in a 7000 Series case could look like, check out this build video we’ve put together:

Better Together: Controlling ASUS RGB Graphics Cards and Motherboards in iCUE

System builders are well aware of the components produced by our friends over at ASUS. If you’ve got ASUS RGB components like a graphics card or motherboard, you can sync their RGB lighting together with the rest of your CORSAIR gear using the CORSAIR iCUE software!

First you’ll need to have your ASUS motherboard and graphics card properly set up while having the latest versions of ASUS Armoury Crate and CORSAIR iCUE installed on your PC.

The process is the same for both components so follow these steps to customize your RGB lighting effects. We’ll use the motherboard setup process as the example.

  1. Open up iCUE and click on the ASUS motherboard icon that should be listed on your profile home interface and select the Lighting Effects tab on the left hand side.
  2. Click the “+” button in the Lighting Layers panel to create a new lighting layer and you’ll see a couple additional panels pop up for additional configuration options.
  3. Every motherboard and graphics card will have different RGB lighting zones, some more or less than others. You can select and deselect the lighting zones you want to customize by clicking on them to see if they are highlighted or not.
  4. The Lighting Type panel will show you a list of lighting effects you can choose from. You can pick one of our preset effects, customize your own, or use the Lighting Link effects to sync all your iCUE-compatible devices on your PC.
  5. The third panel will allow further customization by changing the speed or direction of your lighting effects. Not all effects will have this so it will depend on which effects you choose in the Lighting Type panel.
  6. Additionally, you may add multiple lighting layers in the first menu and apply them to any of your lighting zones for more complex effects.
  • CORSAIR iCUE can control the 12V RGB header on a supported motherboard, however, 5V ARGB header control can only be done through ASUS Armoury Crate.

For supported ASUS graphics cards, you can follow the same steps that we covered for configuring motherboard lighting. Here is a video tutorial on our CORSAIR LAB channel.

Video tutorial on customizing ASUS graphics cards RGB through CORSAIR iCUE 4.

Most supported ASUS graphics cards will only have one lighting zone to customize. You can however add multiple layers in the Lighting Effects menus to that single zone in order to create more complex lighting effects.
