Workstation RAM

Memory capacity is among the factors that computer manufacturers include in large letters on advertisements because it's simple to see that Workstation RAM is more beneficial. 

This time, we're not going to immediately start disputing that statement since it's usually pretty exact. 

What is Workstation RAM?

Workstation Motherboards usually come with three specifications regarding what they can support. 

There will be a limitation of the maximum size of each module, which means it might not be feasible to use, for instance, 64GB DIMMs with specific motherboards. 

Many systems at the level I'm discussing will have a limit of 128GB or less, which means there's no reason to use 64GB modules in the first place. 

Add two, and you're already overcapacity, which means you can consider using four 32s, which will cost less. 

There's also speed, usually referred to as a clock's speed, in megahertz, similar to a workstation CPU, but in the format DDR4-3200 for example.

Single-Sided vs. Double-Sided

A single-sided (more often referred to as a single-ranked) module comes with a single 64-bit wide memory chip. 

The double-sided (double-ranked) module comes with two 64-bit memory banks stacked to provide greater capacity. 

However, a majority, not all of these modules, utilize two sides to store memory. 

However, small memory chips allow "double-sided" modules to have all the chips on the same side. Refer to Figure 4-2. 

It is a one-sided module on top (one 64-bit rank), and the bottom module is double-sided (two 64-bit ranks). 

However, all memory chips reside located on the front of the module.

RAM Compatibility

When it is about memories, the compatibility of each is crucial. 

The type of memory module you choose should be compatible with the motherboard, speed should be compatible, and the memory module/combination size fits your computer system well.

The labels on memory modules in Figure 4-1 indicate the manufacturer, type of module size, and speed. Most also include the LAT (CL) amount. 

If you want to purchase more modules of similar size, you may use this information to buy additional modules.

But, to determine what kind of memory modules work on your motherboard, go to the manufacturer's website and look through the database. 

Make sure you have your model's number on your motherboard and the model of your computer you are using.

Some memory companies offer a web-based application that checks your system for memory installed and recommends memory compatible with the system you're using. 

This type of tool shows the speed and size of memory installed.

Types of Workstation RAM

  • DRAM 

  • SRAM 

  • Synchronous DRAM (SDRAM)

  • Rambus DRAM (RDRAM)

  • Double Data Rate SDRAM (DDR SDRAM)

DRAM

The DRAM (pronounced DEE-workstation RAM) is extensively used as the main computer memory. 

Every DRAM memory cell comprises one transistor and one capacitor inside an integrated circuit. Information is stored inside the capacitor. 

Since transistors are always leaking some amount, capacitors are prone to discharge over time and cause the data stored in the capacitor to be drained. 

As a result, DRAM has to be replenished (given the possibility of a fresh electric charge) every few milliseconds to preserve the data.

SRAM

SRAM (pronounced"ES-workstation RAM'') consists of up to six transistors.

It holds data in memory for as long as power is available to the system, unlike DRAM that has to be refreshed regularly.

Therefore, SRAM is quicker but more expensive, making DRAM the most commonly used memory used in computers.

Synchronous DRAM (SDRAM)

Synchronous DRAM (SDRAM) "synchronizes" the memory speed to the CPU clock speed so that the controller can determine exactly at which the data requested is ready. 

This lets the CPU execute more tasks in the same period. The typical SDRAM transfers data at speeds of up to 133 million MHz.

Rambus DRAM (RDRAM)

Rambus DRAM (RDRAM) is the name behind its Rambus DRAM Rambus. 

It became popular in the 2000s and was mostly used for video game devices and workstation graphics cards

It could be used to speeds of transfer as high as 1 GHz.

Double Data Rate SDRAM (DDR SDRAM)

Double Data Rate SDRAM (DDR SDRAM) is a synchronous memory type that can nearly double the capacity of one-dimensional rate (SDR).

Workstation RAM(SDRAM) running at the same clock speed using a technique known as "double pumping," which permits data transfer at both the falling and rising sides of the clock signals, without any change in the frequency of the clock.
