Over seven months later, Intel CPU instability might be over

We first reported on the Intel CPU instability issue in February 2024, and since then, Intel has offered various fixes that helped, but still failed to fix the problem once and for all. Now, it finally seems like the owners of Intel’s best CPUs might soon be able to rest easy. Intel has shared a new update that pinpoints the four causes of Raptor Lake problems and provides a fix.

Intel’s July update on the matter disclosed that the company was aware of issues within the microcode and that the problem was related to incorrect voltages. Today’s update breaks this down into four operating scenarios that can cause problems. Intel now refers to these long-lasting issues as the “Vmin Shift Instability.”

“Intel has localized the Vmin Shift Instability issue to a clock tree circuit within the IA core which is particularly vulnerable to reliability aging under elevated voltage and temperature. Intel has observed these conditions can lead to a duty cycle shift of the clocks and observed system instability,” said Thomas Hannaford in an Intel community post. Breaking it down into simpler terms, Intel has confirmed that increased voltage affects the stability of these processors, even if operating within warrantied voltages.

Intel’s already provided microcode updates for three out of the four identified root causes behind the Vmin Shift Instability. This includes:

  • Some motherboards pushed the power delivery settings higher than what Intel recommended. This was addressed with Intel’s Baseline Profiles, which ended up being quite confusing.
  • An eTVB (efficient thermal velocity boost) microcode algorithm allowed Intel CPUs to run at higher performance modes despite elevated temperatures, thus endangering the processor. A June 2024 BIOS update fixed this problem.
  • Another microcode algorithm (serial voltage identification, or SVID) requested high voltages combined with just the right frequency and duration to make the CPU unstable. Intel addressed this in August.
  • Finally, Intel reports that the microcode and the BIOS were requesting elevated core voltages, which caused the Vmin Shift Instability when the CPU was running light tasks or even was completely idle.

This final root cause of Vmin Shift is now being addressed by Intel. The company is releasing a microcode update, 0x12B, which includes the previous two updates and also fixes the elevated voltage requests. Depending on your motherboard vendor, you might have to wait — the update is being rolled out and it’ll probably take a little while for everyone’s BIOS updates to be up for grabs.

Intel assured that the new microcode shouldn’t have any impact on performance, citing internal benchmarks in tools like Cinebench R23 or Crossmark, as well as gaming tests in Cyberpunk 2077Shadow of the Tomb Raider, and more. The company also reaffirmed that, despite previous reports, the Vmin Shift Instability doesn’t affect laptops and CPUs of other generations.

Is this really the end of unstable Intel CPUs? We’ll have to wait and see, but right now, Intel certainly appears to think so — and that’s great news for those who are using CPUs like the Core i9-14900K. It might finally be time to breathe a sigh of relief and keep an eye out for those microcode updates.

Trailers of the week: Thunderbolts, Rumors, and Disclaimer

Trailers of the week: Thunderbolts, Rumors, and Disclaimer

This week, I’ve been slowly catching up on Dark Matter; I’m about 20 hours into Paper Mario: The Thousand-Year Door on the Switch; and I’m still trying to work a trip to the movie theater into my schedule to see Beetlejuice Beetlejuice.

I’m behind, in other words! And this week’s trailers shoveled so much more onto my need-to-watch pile, from the next Marvel MCU film, Thunderbolts, to the amusingly bizarre black comedy Rumours, to Disclaimer, Alfonso Cuarón’s new Apple TV Plus series. That’s to say nothing of all the game trailers from Sony’s State of Play event this week.

Check out some of my favorite trailers from this week below.

Thunderbolts

Marvel hasn’t said much about Thunderbolts, which sees David Harbour’s Red Guardian and his daughter, Yelena Belova (Florence Pugh) in a new outing that concludes the MCU’s phase 5 in May next year.

Joining them are Taskmaster (Olga Kurylenko), Ghost (Hannah John-Kamen), Bucky Barnes (Sebastian Stan), and John Walker (Wyatt Russell), with Valentina Allegra de Fontaine (Julia Louis-Dreyfus) as their apparent ring leader. There’s also a mystery character named Bob (Lewis Pullman) who, as The Verge’s Charles Pulliam-Moore hinted earlier this week — and Polygon went at head-on — is probably Sentry, a Marvel version of Superm—er, a flying bulletproof guy with superhuman strength, speed, and agility.

Rumours

I’m trying to think of the best thing to compare Rumours to. The big, sans-serif, drop-shadowed fonts scream 1970s-era exploitation films, as do its backlit fog and sometimes pinkish tint, which makes it look a bit like a well-aged film print.

The trailer has notes of Wes Anderson’s deliberate blocking and framing, mixed with the absurdism of Quentin Dupieux’s Rubber. There’s a gigantic brain? And some zombies. And leaders of the G7 nations, trapped in the woods with all of that. Whatever it is, Rumours, a black comedy from co-directors Guy Maddin, Evan Johnson, and Galen Johnson looks like it’ll be a hoot when it hits theaters on October 18th.

Sinners

Sinners sees one of director Ryan Coogler’s mainstay actors, Michael B. Jordan, playing 1930s twin brothers who go back to their hometown to start over, only to be confronted by some unknown horror. 

The name and trailer point to a religious theme. (“You keep dancing with the devil, one day he’s gonna follow you home.”) But shadowy figures outside a juke joint and a young boy walking into a church with fresh claw marks on his face hint at more. Maybe it’s a murderous cult, maybe the town is beset by actual demons. What’s really going on is a total mystery, and hopefully, it’ll stay that way until its March 7th theatrical release.

Alfonso Cuarón’s new Apple TV series, Disclaimer, is a seven-part psychological thriller that starts streaming on October 11th. Cate Blanchett stars as a journalist named Catherine Ravenscroft, whose dark secrets are revealed in an anonymously written novel that is sent to her. 

The secrets are apparently bad enough to threaten her relationship with her husband, Robert (Sacha Baron Cohen), and her son, Nicholas (Kodi Smit-McPhee). The series also stars Kevin Kline, Lesley Manville, Louis Partridge, Leila George, and Hoyeon, and it’s narrated by Indira Varma.

Since I became science fiction columnist for New Scientist, I have had to think a lot about what qualifies as sci-fi. Very often, a book could actually be classified as fantasy, which is outside my remit. More and more, I find myself agreeing with the writer Damon Knight when he said: “Science fiction is what I point to [when I say] ‘That’s science fiction’.”

Anyway, for this holiday reading special, I present my list of some of the year’s best sci-fi so far. All that binds these incredibly diverse books…

Next Apple HomeKit device could blend HomePod, iPad, and AI

Next Apple HomeKit device could blend HomePod, iPad, and AI

Apple HomeKit has always lagged behind Alexa and Google Assistant, notably lacking a smart display similar to that of the Echo Show 15 or the Nest Hub. Rumors suggest that the company’s next gadget might rectify that. MacRumors reported code found in Apple’s backend that referenced something called HomeAccessory17,1. That might not seem like much to go on until you realize that HomePod is similarly named AudioAccessory.

There are still too few details to make any definitive conclusions, but we can venture an educated guess that the upcoming device might be powered by the A18 chip and feature AI-focused features. Apple already has plans to integrate OpenAI and Siri. Adding AI-powered intelligence into a smart home system would potentially give it never-before-seen functionality — perhaps even more than what Alexa can currently offer, although Google Assistant’s use of Gemini could level the playing field.

The code also hinted that the HomeAccessory — probably not the final name of the product — would run on a version of tvOS. If true, then this new gadget might be a chimera-like build of the iPad and HomePod. It’s speculation, but it might look similar to the Google Pixel Tablet.

Other rumors suggest the next HomeKit device could contain a camera for user identification and gesture recognition. Again, take all of this with a grain of salt — none of it has been confirmed yet, but it’s exciting to see new developments in a smart home platform that has largely been underrepresented.

With confirmed changes coming to HomeKit in iOS 18 like enhanced guest controls and robot vacuum support, HomeKit might finally be getting the attention it needs.
