From the how-about-that department: An anonymous reader shares a report: Earlier this month, we wrote that some of Intel's recent high-end Core i9 and Core i7 processors had been crashing and exhibiting other weird issues in some games and that Intel was investigating the cause. An Intel statement obtained by Igor's Lab suggests that Intel's investigation is wrapping up, and the company is pointing squarely in the direction of enthusiast motherboard makers that are turning up power limits and disabling safeguards to try to wring a little more performance out of the processors.
"While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards," the statement reads. "Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency."
These are the specific settings that Intel believes are causing problems:
Disabling Current Excursion Protection (CEP)
Enabling the IccMax Unlimited bit
Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB)
Additional settings which may increase the risk of system instability:
Disabling C-states
Using Windows Ultimate Performance mode
Increasing PL1 and PL2 beyond Intel recommended limits.

From the how-about-that department: Razer will have to fork over $1.1 million in refunds to customers who purchased its RGB-clad Zephyr face mask, according to a proposed settlement announced by the Federal Trade Commission on Monday. From a report: The company claimed the face mask used N95-grade filters, but the FTC alleges Razer never submitted them for testing and only "stopped the false advertising following negative press coverage and consumer outrage at the deceptive claims."
Razer first released its Zephyr face mask in 2021 as a nifty, cyberpunk-esque alternative to traditional face masks worn during the covid-19 pandemic. Although Razer initially marketed the $100 mask as having N95-grade filters, it scrubbed any mention of the grade after YouTuber Naomi Wu tore down the mask and found that it wasn't N95 certified after all. N95 masks are supposed to filter out at least 95 percent of airborne particles, according to the Centers for Disease Control and Prevention. Razer also planned on launching a $150 Zephyr Pro with a voice amplification feature, but that never panned out. At the time, Razer addressed claims about its Zephyr masks, saying in a post on X that "the Razer Zephyr and Zephyr Pro are not medical devices, respirators, surgical masks, or personal protective equipment (PPE) and are not meant to be used in medical or clinical settings."

From the truckin' department: Oakland, California is now home to "the first commercial hydrogen fuel station for big-rig trucks in the United States," according to the Los Angeles Times — serving 30 hydrogen fuel-cell trucks.
The newspaper says the facility "could mark the start of a nationwide network for fuel-cell truck refueling. It could also flop."
Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. The fuel cells, which drive electric motors to drive the truck, are enormously expensive as well.... The vehicles themselves are expensive too. Both battery electric and hydrogen fuel-cell trucks can cost three times as much or more than a $120,000 diesel truck. Those buying the trucks can qualify for state and federal subsidies to make up most of the upfront costs.
But government regulations may spark some demand:
New diesel truck sales will be outlawed in California by 2036. Only zero-tailpipe-emission new trucks will be allowed. Already, zero-emission requirements are in place for trucks that enter ocean ports. And only two technologies are available to achieve that goal: battery electric trucks and hydrogen fuel-cell trucks. "We believe a good portion of those will be hydrogen vehicles," said Matt Miyasato, chief of public policy for hydrogen fuel distributor FirstElement Fuel. FirstElement, through its True Zero brand fueling stations, is the largest hydrogen vehicle fuel distributor in the U.S...
Battery electric is gaining a strong foothold in the medium-sized delivery truck market, but hydrogen could have a leg up for long-haul trucking. While a fuel cell is comparable in size to a diesel engine, a battery big enough for long-haul trucks adds weight and size and cuts down on the total freight load the truck can deliver. And while an electric truck battery can take hours to recharge, the refill time for hydrogen is more comparable to filling up with diesel fuel.
