Industrial RAM modules from GOODRAM at TME
Industrial RAM modules are a new addition to the TME catalogue, get started with modules from GOODRAM.
Computerisation of the industry, and the IT industry itself, have become ‘a sign of the times.’ With the exploitation of electronics being more intensive than ever, electronic components have to be designed for constant use and extreme, often suboptimal operating conditions.
Industrial RAM modules are a new category in the TME catalogue. The first to arrive were the products from GOODRAM, a Polish company with 30 years of experience. As of today, GOODRAM is the only manufacturer of RAM modules in Europe, well-known and trusted by customers from many countries in the EU and beyond.
That being so, we would like to provide our customers with an overview of the products offered by this supplier and present some basic concepts related to RAM modules used in computers, servers, industrial automation drivers and integrated compact systems such as IoT or embedded.
In this article, we will touch upon the following subjects:
- Why do computers need RAM?
- SDRAM, SODIMM and other acronyms from the computer world
- How is RAM adapted for industrial applications?
- What are the differences between DDR3, DDR4 and DDR5 memory modules?
A few words about RAM
Random access memory is one of the most important components of a conventional computer, as without it, the device will not boot. The CPU uses it for storing data – therefore, it is directly controlled and accessed by the central processing unit. In newer systems, it can also serve other functions, e.g. be shared with the GPU. In other words, the speed and quality of RAM directly affect how the computer functions. What is more, the evolution of such components is linked to the evolution of the CPU architecture, which is why whenever we want to purchase a memory module we have to check if its speed, capacity, and version are supported by our CPU model. Such information, being one of the most important details, is always listed in the specifications of the CPU.
What makes GOODRAM products stand out?
Industrial conditions require from manufacturers a lot of emphasis on the durability and longevity of their components. Memory modules included in the GOODRAM Industrial series are designed with such applications in mind. A perfect example of this is the wide thermal tolerance displayed by these RAM modules (they can operate in a temperature ranging from 0°C to 85°C) and the high quality of integrated circuits incorporated into their design. In addition, selected products also support the ECC (Error Correction Code) technology which is a method used for detecting and correcting errors in data transmission – this guarantees that the computer will run smoothly without any interruption, even during constant and intensive memory use. It is also important to note that the modules undergo extensive longevity and thermal resistance tests, and are manufactured in a factory located in the European Union.
GOODRAM Industrial RAM modules have been produced and designed for automotive, home and industrial automation applications. They can be also mounted inside self-checkouts and other self-service machines (parcel lockers, ticket machines), IoT devices (Internet of Things) or even medical equipment.
DDR memory generations
As we have mentioned above, the “DDR” acronym is often associated with the subsequent generations of computer RAM modules. In the case of the products from the GOODRAM Industrial offer, there are three types of RAM available: DDR3, DDR4, DDR5. Due to the fact that these versions are not interchangeable, and the technology used to manufacture them is directly linked to their parameters and capabilities, below we present a short description of memory modules you can purchase from the TME catalogue.
These RAM modules are still used in some systems, mainly those which are based on reliable motherboards. The products offered by GOODRAM can also be used for performing upgrades and maintenance work on older computers. The DDR3 modules exhibit energy consumption levels that are lower than the ones displayed by their predecessors, which is why they quickly gained popularity and began to be commonly used in mobile devices and compact computers. The industrial DDR3 RAM modules are compatible with buses operating at up to 1600 MHz and offer a choice of the following capacities: 2 GB, 4 GB and 8 GB.
As of now, this is the most popular type of RAM. When it was first launched, DDR4 offered a number of innovative solutions: a lower power supply voltage (1.2 V DC), address parity bit and DBI (Data Bus Inversion), i.e. the technology for data bus inversion which was applied in order to reduce the energy consumed by RAM. The DDR4 modules from GOODRAM Industrial can be purchased in capacities ranging from 4 GB to 32 GB and operating at a frequency of up to 3200 MHz, meaning that the speed of data transfer can reach up to 25600 MB/s.
This is the newest generation of DRAM. The upgrades, which include the power management integrated circuit, made it possible to achieve an even lower level of energy consumption (reduced by 15% in comparison to the previous solutions). Not only did such a design improve the parameters and stability of data transfer but it also simplified the structure of motherboards. Furthermore, DDR5 utilizes dual 32-bit channels which doubles the efficiency of older RAM modules.
In the TME catalogue, you can find GOODRAM Industrial DIMM and SODIMM memory modules operating at the frequency of 4800 MHz. They offer a choice of the following total capacities: 8 GB, 16 GB and 32 GB.
