I have a gaming notebook - see sig - with 16 GB RAM. Runs perfectly fine.
On normal occasions memory usage is around 31-33%. When playing games like Cyberpunk 2077 it runs to 57-60%.
Is more RAM needed, or just a nice-to-have?

Raspberry Pi Foundation unveils a case fan for the Raspberry Pi 4
by Jefferson Mangubat
The Raspberry Pi Foundation has released a case fan for the Raspberry Pi 4. The $5 fan is available to purchase starting today and it is built to keep the single-board computer from overheating.
Combined with a small heatsink, the fan works with the official case that comes with the Raspberry Pi 4, which was announced last year. It's powered by a 1.5GHz quad-core ARM Cortex-A72 processor called Broadcom BCM2711, marking a significant upgrade from its predecessor.
That said, the Raspberry Pi 4 can get hot when it runs at maximum performance for a long period and eventually throttles the CPU's frequency to minimize heat, a feature called sprint-and-recover mode. This happens under certain conditions such as when you’re using a case, which can block proper ventilation, or when the computer overclocks to 1.8GHz or higher.
Over the last 18 months, the foundation has addressed this issue with power optimization feature that it released in November of last year. While that update fixed the problem in some cases, the overheating issue arises when the Raspberry Pi is used for extended periods.
The foundation describes how the new case fan works: "It draws air in over the USB and Ethernet connectors, passes it over a small finned heatsink attached to the processor, and exhausts it through the SD card slot." A test workload that ran with the fan demonstrated that the board managed to keep its temperature below 70 degrees Celsius.
The fan is available to purchase for $5 via Raspberry Pi approved resellers in select countries. In the future, the foundation will expand its availability to more territories not yet included in the list.
IBM, Red Hat and others want inclusive language in software
by Paul Hill
IBM, Red Hat and VMWare are among several companies that have come together to create the Inclusive Naming Initiative which aims to eliminate problematic language from projects and replace them with an agreed set of neutral terms. To do this, the initiative will define processes and tools to remove harmful language from projects.
Some of the processes and tools which the Inclusive Naming Initiative will be creating include a comprehensive list of terms with replacements, language evaluation frameworks and templates, and infrastructure to aid the transition.
Explaining the need for more inclusive words, the initiative says:
Initially, attention will be aimed at replacing the terms ‘master’, ‘slave’, ‘whitelist’ and ‘blacklist’ because these are the most visible and problematic across the industry. Over time, it will expand its scope to find replacements for other terms that reference mental health, gender, physical handicaps, and several other categories. In the future, it might also give tips to avoid colloquialisms that don’t translate into other languages very well or are a barrier to understanding.
While some people may be against the changing of these terms, the Inclusive Naming Initiative argues that the neutral terms are more descriptive, for example, it says that ‘Denylist’ is more precise and more accurate than ‘blacklist’.

SK hynix introduces DDR5 DRAM, the first in the world
by João Carrasqueira
SK hynix, a well-known manufacturer and developer of memory chips, today announced the launch of the world's first DDR5 DRAM. About two years ago, the company had announced it was developing the first 16Gb DDR5 DRAM, and today the company delivered on that goal.
DDR5 is the next evolutionary step in memory technology, and it continues the trend of the past few generations, further lowering the operating voltage to 1.1V from 1.2V. This allows the unit to consume even less power, with SK hynix claiming a 20% reduction. Additionally, the new memory offers significantly faster transfers, with a transfer rate between 4,800Mbps and 5,600Mbps, 1.8 times higher than the range DDR4.
In addition to being much faster, the new DDR5 DRAM also includes error correcting code (ECC), which can correct 1-bit-level errors and increase application reliability by up to 20 times.
SK hynix also said that it will continue to work with other partners in the memory chip business to develop the DDR5 ecosystem. Some partners, like Montage Technology, already have DDR5 products listed on their websites, but SK hynix itself doesn't appear to show any as of yet. At this time, DDR5 products are being geared towards high-performance computing tasks like Big Data, AI, and machine learning, so it may be some time before general consumers get to have it in their computers. Additionally, support for this memory is only planned for future generations of Intel and AMD processors.
Samsung discovers new material for semiconductors
by Paul Hill
Samsung has announced the joint discovery of a new material called amorphous boron nitride (a-BN). Its researchers at the Samsung Advanced Institute of Technology (SAIT) worked with the Ulsan National Institute of Science and Technology (UNIST) and the University of Cambridge to make the discovery. The collaborators published their findings in the Nature journal and believe that the material will “accelerate the advent of the next generation of semiconductors.”
Explaining the newly discovered amorphous boron nitride, Samsung said it consists of boron and nitrogen atoms with an amorphous molecule structure. The Korean firm said that the new material is derived from white graphene but that the different molecular structure makes a-BN “uniquely distinctive” from white graphene.
Samsung said that a-BN is expected to be widely used in DRAM and NAND solutions because it’s able to minimise electrical interference and can be grown on a wafer-scale at a relatively low temperature of 400°C.
Commenting on the material, Hyeon-Jin Shin, a graphene project leader and Principal Researcher at SAIT, said:
The firm didn’t give a date on when it hopes to start using the new material in its hardware products but did say that it would be applied to semiconductors, especially DRAM and NAND solution, in next-gen memory solutions for large-scale servers.
