Slashdot: Why Are Laptops Moving to Soldered RAM?

Why Are Laptops Moving to Soldered RAM?
Published on April 29, 2024 at 12:43AM
This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair." "This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year. After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board." This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery.... All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer." SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, so "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth." But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

Slashdot: Spain-Backed Fund Joins FOSSA's Sovereign Satellite Communications Push

Spain-Backed Fund Joins FOSSA's Sovereign Satellite Communications Push Published on 2026-06-28T22:05:00Z Spanish startup FOSSA Systems "has raised about $10.5 million to expand its connectivity constellation," reports Space News, noting some funding is backed by Spain's government: The support from the Spanish Society for Technological Transformation (SETT) comes a year after the fund injected 14 million euros into Spain's Sateliot , which is also developing a satellite connectivity network with security and defense applications. Spanish private investment firm Kibo Ventures led FOSSA's funding round, the six-year-old venture announced June 24, bringing its total raised to date to nearly 20 million euros. The proceeds will help fuel FOSSA's push beyond the tiny picosatellites it once used to connect low-power monitoring devices toward larger cubesats in low Earth orbit, enabling additional sovereign communications and space-based intelligence capab...

Slashdot: AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age

AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age Published on 2026-03-10T20:00:00Z AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said. The spending will focus on expanding its fiber and wireless networks, including accelerating deployment of fiber broadband, 5G home internet and satellite co...
