Users complain about mysterious crashes of new Macs – crackling and sudden reboots

Published

on

There are more and more complaints on the network about mysterious failures of new Mac computers based on Apple’s proprietary M1 SoC.

The situation is such – a crackling sound is heard, as from static electricity, and then a sudden reboot follows. As noted by the publication ZDnet, the sound is made by the speaker, not the “roasting electronics”. At the same time, complaints are becoming more common in Apple communities.

Mac mini and Apple M1-based MacBook users report crashes and restarts with the bewildering error “SOCD report detected: (AP timer expired)”.

Reboots happen in different conditions, but most often – with devices connected to Thunderbolt 3, such as external drives, docking stations, and so on. Different versions of the operating system are used – both macOS Big Sur 11.4 and macOS Big Sur 11.5.

Apple itself has not yet commented on the situation.

There may be problems with the official repair of Xiaomi

As of today, Xiaomi has stopped after-sales service for several of its phones released in 2018 and 2019. We are talking about Xiaomi Mi 8, Mi 9 SE, Mi 9 Explorer, Mi 9, Redmi K20 Pro and Redmi K20 Pro Premium. The company no longer produces spare parts for them, and the official service may refuse to repair.

At the same time, in a company service, if necessary, they will be able to test the phone and diagnose a possible problem, as well as clean it. A full repair can be carried out by third-party services.

Xiaomi has also excluded the Redmi K20 Pro and Redmi K20 Pro Premium from its battery replacement program. Apparently, for the same reason: batteries for these phones are no longer produced.

Tesla Dojo Supercomputer Unveiled So Powerful It Shut Down Power

Tesla unveiled its latest iteration of its Dojo supercomputer, which proved to be so powerful it shut down the power grid in Palo Alto.

Dojo is Tesla’s own dedicated supercomputing platform, built from the ground up for AI machine learning and specifically for video training using video data coming from Tesla electric vehicles.

The automaker already has a large supercomputer powered by Nvidia GPUs, which is one of the most powerful in the world, but Dojo’s new custom computer uses Tesla-designed chips and infrastructure.

The new supercomputer will boost Tesla’s ability to train neural networks using video data, which is critical for computer vision technology to enable self-driving driving. A year ago, the company first announced the creation of Dojo. Now she spoke about the progress made over the year.

Tesla claims it can replace 6 GPU blocks with a single tile (Dojo tile), which the company claims costs less than one GPU block. On a tray (system tray) 6 such tiles. One tray is equivalent to “3-4 fully loaded supercomputer racks”. Tesla can accommodate two of these system trays in the same Dojo chassis. Tesla is still developing and testing the infrastructure needed to combine multiple cabinets to create the first Dojo Exapod, whose main specifications are already known: 1.1 EFLOP, 1.3TB SRAM, and 13TB high-bandwidth DRAM.

“We knew we needed to rethink every aspect of the data center infrastructure to deliver unprecedented cooling and power density,” said Bill Chang, Tesla’s chief system engineer for the Dojo project.

They had to develop their own powerful cooling and power system for Dojo cabinets. Chang confirmed that Tesla shut down its local power grid substation while testing Dojo: “Earlier this year, we began stress testing our power and cooling infrastructure and managed to increase capacity by more than 2 MW before we shut down our substation and received a call from cities”.

There are currently plans to build seven Dojo Exapods in Palo Alto.

MediaTek beats Qualcomm again Asus ROG 6 Dimensity Supreme Edition

The developers of the AnTuTu benchmark have published another performance rating of top smartphones for September. It has only one model on a MediaTek single-chip platform, but it is also the best.

The recently unveiled Asus ROG 6 Dimensity Supreme Edition, based on the Dimensity 9000+, topped the rankings with a score of 1,123,036 – no other phone (and all nine models are built on Snapdragon 8 Plus Gen 1) could beat this result.

In this context, it is interesting to evaluate the results of the survey conducted by GSMArena. The journalists wondered how interesting users are both the Asus ROG 6 Dimensity Supreme Edition itself and its versions on Qualcomm and MediaTek SoCs. It turned out that out of almost 1700 participants, only 341 are ready to purchase the Dimensity 9000+ version, while almost twice as many respondents prefer the Snapdragon 8 Plus Gen 1 version of the phone.

It turns out that users tend to trust models based on SoC MediaTek less, even though they demonstrate performance at the level (and in this particular situation, even higher) of Qualcomm SoC.
