Everything you need to know about Crucial memory

What is a Memory Rank?

26-March-2019

The concept of memory rank applies to all memory module form factors, though in general it tends to matter primarily on server platforms, due to the larger amounts of memory they manage.

1.35v - 1.5v Dual-Voltage DDR3 Memory

04-April-2019

Voltage refers to the power consumed by a module. In the past, most DDR3 memory voltage ranged from 1.5 - 1.65v. More recently, dual 1.35/1.5 voltage modules came available at Crucial.com.

Understanding CPU Limitations with Memory

26-March-2019

With modern CPUs the memory controller is built directly into the CPU itself, which means different types of CPUs may support different speeds of memory.

What are Memory Timings?

26-March-2019

If we think of memory as a race car, the module speed (MH/z) would be like the raw horse power of the engine, and the timings would be the driver of the car.

Why Doesn't Windows® Recognize All of My Memory?

26-March-2019

The maximum amount of memory that your system can use is limited in two ways. There is a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept.

ECC vs. non-ECC - What do I Have and Can I Mix?

26-March-2019

You can determine if your system has ECC by simply counting the number of black memory chips on each module. ECC memory modules have a chip count divisible by three or five.

Overview of Memory Chip Density

26-March-2019

The density of a memory module is determined by the small black DRAM chips that make up the memory module. The fewer chips there are on the module, the higher the density.

What is XMP?

26-March-2019

Extreme Memory Profile (XMP) speeds are higher performing, and are usually custom tweaked to the specific needs of the memory.

How Much Power Does Memory Use?

26-March-2019

As a rule of thumb, you want to allocate around 3 watts of power for every 8GB of DDR3 or DDR4 memory. High-performance memory such as Ballistix® parts can draw more power, especially if you overclock the voltage beyond XMP settings.

What Is The Difference Between DDR4, DDR3, DDR2, DDR, and SDRAM?

26-March-2019

The most significant difference between DDR and SDR is that DDR reads data on both the rising and falling edges of the clock signal, enabling a DDR memory module to transfer data twice as fast as an SDR memory module.
