Hyperbook - absolute memory - what is worth knowing about RAM
Your computer uses many types of memory. Of course, the best solution is to use a large amount of fast memory, but the price is an obstacle here. Therefore, the faster and more expensive the memory, the less it is. Simply put, there are three main types of memory. The first is non-volatile memory, i.e. the one whose contents are not lost when the power is turned off. A perfect example here are HDDs and faster, but also more expensive SSDs. We store all files on disks. RAM memory, the content of which is erased when the computer is turned off, is a kind of scrapbook for the processor where it stores the data needed for current work and calculations. RAM is at least several times faster than already fast SSDs. The third type of memory, again much faster than RAM, is several levels of cache inside the CPU. This one is the fastest so that the processor does not have to wait for access to it, but also the most expensive. Of course, this is not all types of computer memory, but for the purposes of this article, it is a good approximation.
How much RAM is enough?
Basically, the more RAM the better, but don't overdo it. A typical office laptop can handle 8GB of RAM. However, if we have such an opportunity, it is worth choosing 16 GB - Windows will speed up work with many applications. 16 GB is also basically the standard when we choose a gaming machine. Some games may not run on 8GB. In the event that we use applications that are particularly memory-intensive, e.g. professional ones, it is worth considering equipping the computer with 32 and sometimes even 64 GB of RAM. A special case in which it is worth buying more RAM than the minimum of 8 GB is when the computer uses a graphics card built into the processor. Such a card, unlike a dedicated one, does not have its own memory and uses the system memory. This means that out of our 8 GB, only about 6 GB is available for Windows, which negatively affects performance.

RAM has evolved with the development of computers and its types have changed. Currently, the most popular is DDR4, but by the end of 2021 we will most likely see DDR5. Older computers, on the other hand, use DDR3. Different types of RAM modules are shaped so that they do not fit into other slots. However, for those who want nothing difficult - if someone insists, they will push the module into the wrong slot and then the memory or motherboard failure is guaranteed. From the point of view of the laptop user, it is also worth remembering that the modules for portable computers are smaller than for desktop computers and have a form called SO-DIMM. Memories also differ, like processors, in the clock with which they operate. This parameter should be taken into account when buying memory, because modern processors are relatively sensitive to memory speed. Therefore, you should not use chips slower than the nominal speed of the memory controller built into the processor.
Currently, depending on the processor, it is 2933 to 3200 MHz. For older systems, however, it can be even 2133 MHz. Modules with a speed of 3600 MHz have an optimal price-performance ratio. Faster modules are very expensive and performance gains are not so spectacular.
RAM in Hyperbooks
In Hyperbook computers, we use very good quality memories produced on special order by Wilk Elektronik SA. Modules specially prepared for us are characterized by high efficiency and reliability. By the way, we support the Polish industry, because the production lines of Wilk Elektronik SA are located in our country. Assembled systems are 100 percent subject to multi-stage control. The quality of welds and the correctness of soldering is visually controlled. The culmination of the assembly process is the selection carried out by the AOI device through an automated warehouse. AOI separates PCB multiblocks into those without defects, the so-called passes and multiblocks in which a discrepancy was found, the so-called fails. Elements in the housings are checked by X-rays.
The next stages are electrical and application tests - it is a simulation of typical working conditions in a computer. A special application developed by Wilk Elektronik SA saves and reads tens of gigabytes of data, detecting even single errors. Finally, the modules undergo thermal tests. Thermal acceleration test shortening the time needed to observe potential damage, and a test in a climatic chamber at temperatures from -70 to +180 degrees Celsius.
