On the Internet we can find a large number of simple projects for the restless and DIY enthusiasts. It is common to develop smart mirrors, automatic irrigation systems or video intercoms, among others, based on Raspberry Pi. The YouTuber Bits und Bolts has developed his own RAM memory modules which works perfectly.
Any type of computer that we imagine needing must have RAM memory. This type of memory is essential for the processor to be able to store a certain amount of information. This type of memory is used because of the high transfer speeds it offers.
What any of us would do is go to any store and buy the amount we need. But what if you need a type of RAM that is no longer manufactured? That’s what happened to content creator Bits und Bolts and he decided to create his own modules.
YouTuber Created His Own RAM Memory Modules
Acquiring DDR3 memory is quite simple, you can even find DDR2 and DDR1 modules with relative ease. But it gets complicated when we talk about older standards, like the 30-pin SIMM format. They are very difficult to find, which is why this user created them.
Bits und Bolts had an old system that I wanted to increase the amount of RAM on. The problem was that most of the SIMMs available were 8MB or less. So they developed their own SIMMs with 16MB per module. Most impressive of all, they are very easy to manufacture, providing a guide to components and assembly.
Note that this YouTuber had already uploaded an interesting video creating 30-pin SIMM solutions with a capacity of 4 MB. In this case, he went further and quadrupled the capacity of each tablet.
These memories were designed for a system equipped with an Intel 80386 processor. You should know that at that time memories were normally 4 MB and 8 MB ones were rare, while 16 MB ones are very rare to see and also expensive. like no There are new ones, they are all used.
For all these reasons, it launched its own 30-pin SIMMs with a capacity of 16 MB. The idea was to explore the limits of the system with the Intel 80386 processor.
Before starting the process, I looked at the technical specifications and manuals of the 80386 motherboard. I wanted to know if it could boot with 64MB of RAM, which was unclear to me. Well, he found out that it could if he filled four of the eight available RAM slots.
One of the interesting aspects of their tests was the use of memtest software. This tool is widely used to see the performance of RAM and check for possible errors. Well, this program, which normally does the job in a few minutes, took no less than 10 hours to complete a test on the 64 MB of RAM installed.
During development, the problem of ensuring that the memory was FPM and not EDO was encountered. To solve the problem, the modules have the ability to switch between the two operating modes.
We can see in another video how Windows 3.1 manages to run without any problems. Currently, Bits und Bolts is already working on how much additional memory it can install in a system based on an Intel 80486.
