Asus Details ROG Matrix GeForce RTX 4090: Liquid Cooling Meets Liquid Metal

Asus has introduced a new flagship RTX 4090 graphics card that uses an all-in-one liquid cooling system combined with liquid metal thermal interface. Dubbed the ROG Matrix GeForce RTX 4090, Asus says that its advanced cooler combined with extremely efficient thermal interface will ensure the maximum boost clocks possible, with Asus taking clear aim of producing the fastest gaming graphics card on the market.


Proper power delivery and efficient cooling are main ways to enable consistently high CPU and GPU performance these days, so when designing its ROG Matrix GeForce RTX 4090, the company used its own proprietary printed circuit board (PCB) with an advanced voltage regulating module (VRM). Meanwhile cooling is being provided by an all-in-one liquid cooling system that removes heat not only from GPU, but also from memory and VRM, exhausting that heat via the attached “extra-thick” 360mm radiator.


But Asus says that its ROG Matrix GeForce RTX 4090 has a secret ingredient that its rivals lack: liquid metal thermal interface material (TIM) that ensures superior heat transfer from hot components to cooling systems. 


Asus does not disclose what type of liquid metal TIM it uses for graphics cards (it uses ThermalGrizzly’s Conductonaut Extreme for some laptops), bus usually such thermal interfaces are made from gallium or gallium alloys, which are liquid at or near room temperature and are great conductors of heat.



But there are also some risks and challenges associated with using liquid metal thermal interfaces. Firstly, they are electrically conductive, which means that if the material spills or is not properly contained, it could cause a short circuit. Secondly, these materials can be corrosive to certain metals like aluminum. Thirdly, applying liquid metal can be more complicated than using other types of thermal paste, requiring careful handling and precision.


Asus says that it has been using liquid metal TIMs in its laptops for years, so using them for graphics cards does not seem to be a big challenge for the company.

Asus is not disclosing the complete specifications of the ROG Matrix GeForce RTX 4090 for the moment, but it certainly hopes to make the graphics card the world’s fastest. It remains to be seen whether the product will indeed be the fastest out-of-box, but it will certainly offer a noteworthy overclocking potential when compared to regular GeForce RTX 4090 graphics boards with regular coolers.


The Asus ROG Matrix GeForce RTX 4090 will be a limited-edition card available for sale in Q3.

The world of biomedicine has developed a lot of technology that seems a small step removed from science fiction, but the public isn’t aware of much of it. mRNA-based vaccines, though, were a big exception as a lot of the public tracked the technology’s development as a key step toward emerging from the worst of the pandemic and then received the vaccines in droves.

mRNA technology has a lot of potential applications beyond COVID, and we talked a bit about those during the “Beyond COVID: What Does mRNA Technology Mean for Disease Treatment?” panel at last week’s Ars Frontiers event. We’ve archived the panel on YouTube; if you want to focus on the discussion about mRNA therapies, you can start at the 1-hour, 55-minute mark.

mRNA is a nucleic acid molecule that instructs the cell to make specific proteins. When used as vaccines, the instructions call for a protein produced by a pathogen, such as a virus. “It helps put up a wanted poster for the immune system,” was how Nathaniel Wang, co-founder and CEO of Replicate Bioscience put it.

Corsair Unveils Dominator Titanium DDR5 Kits: Reaching For DDR5-8000

Corsair has introduced its new Dominator Titanium series of DDR5 memory modules that will combine performance, capacity, and style. The new lineup of memory modules and kits will offer DRAM kits up to 192 GB in capacity at data transfer rates as high as DDR5-8000.


The Dominator Titanium DIMMs are based on cherry-picked memory chips and Corsair’s own printed circuit boards to ensure signal quality and integrity. Also, these PCBs are supplemented with internal cooling planes and external thermal pads that transfer heat to aluminum heat spreaders, with an aim on keeping the heavily overclocked DRAM sufficiently cooled.



With regards to performance, the retail versions of the Titanium kits will run at speeds ranging from DDR5-6000 to DDR5-8000. Which, at the moment, would make the top-end SKUs of the highest clocked DDR5 RAM on the market. Corsair is also promissing kits with CAS latencies as low as CL30, though absent a full product matrix, it’s likely those kits will be clocked lower. The DIMMs come equipped with AMD’s EXPO (AMD version) and Intel’s XMP 3.0 (Intel version) SPD profiles for easier overclocking.


As for capacity, the Titanium DIMMs will be available in 16GB, 24GB, 32GB, and 48GB configurations, allowing for kits ranging from 32GB (2 x 16GB) up to 192GB (4x 48GB). Following the usual rule curve for DDR5 memory kits, we’ll wager that DDR5-8000 kits won’t be avaialble in 192GB capacities – even Intel’s DDR5 memory controller has a very hard time with running 4 DIMMs anywhere near that fast – so we’re expecting that the fastest kits will be limited to smaller capacities; likely 48GB (2 x 24GB).


Corsair is not disclosing whose memory chips it uses for its Dominator Titanium memory modules, but there is a good chance that it uses Micron’s latest generation of DDR5 chips, which are available in both 16Gbit and 24Gbit capacities. Micron was the first DRAM vendor to publicly start shipping 24Gbit DRAM chips, so they are the most likely candidate for the first 24GB/48GB DIMMs such as Corsair’s. And if that’s the case, that would mark an interesting turn-around for Micron; the company’s first-generation DDR5 modules are not known for overclocking very well, which is why we haven’t been seeing them on current high-end DDR5 kits.

Corsair has also taken into account aesthetic preferences by incorporating 11 addressable Capellix RGB LEDs into the modules. Users can customize and control these LEDs using Corsair’s iCue software. For those favoring minimalism, Corsair offers separate Fin Accessory Kits. These kits replace the RGB top bars with fins, bringing a classic look reminiscent of the original Dominator memory.


While Corsair’s new Dominator Titanium memory modules are already very fast, to commemorate their debut Corsair plans to release a limited run of First-Edition kits. These exclusive kits will feature even higher clocks and tighter timings – likely running at DDR5-8266 speeds, which Corsair is showing off at Computex. Corsair intends to offer only 500 individually numbered First-Edition kits.



Corsair plans to start selling its Dominator Titanium kits in July. Pricing will depend on market conditions, but expect these DIMMs to carry a premium price tags.

Lawyer Cited 6 Fake Cases Made Up By ChatGPT; Judge Calls It 'Unprecedented'

An anonymous reader quotes a report from Ars Technica: A lawyer is in trouble after admitting he used ChatGPT to help write court filings that cited six nonexistent cases invented by the artificial intelligence tool. Lawyer Steven Schwartz of the firm Levidow, Levidow, & Oberman “greatly regrets having utilized generative artificial intelligence to supplement the legal research performed herein and will never do so in the future without absolute verification of its authenticity,” Schwartz wrote in an affidavit (PDF) on May 24 regarding the bogus citations previously submitted in US District Court for the Southern District of New York.

Schwartz wrote that “the use of generative artificial intelligence has evolved within law rms” and that he “consulted the artificial intelligence website ChatGPT in order to supplement the legal research performed.” The “citations and opinions in question were provided by ChatGPT which also provided its legal source and assured the reliability of its content,” he wrote. Schwartz admitted that he “relied on the legal opinions provided to him by a source that has revealed itself to be unreliable,” and stated that it is his fault for not confirming the sources provided by ChatGPT. Schwartz didn’t previously consider the possibility that an artificial intelligence tool like ChatGPT could provide false information, even though AI chatbot mistakes have been extensively reported by non-artificial intelligence such as the human journalists employed by reputable news organizations. The lawyer’s affidavit said he had “never utilized ChatGPT as a source for conducting legal research prior to this occurrence and therefore was unaware of the possibility that its content could be false.”

Federal Judge Kevin Castel is considering punishments for Schwartz and his associates. In an order on Friday, Castel scheduled a June 8 hearing at which Schwartz, fellow attorney Peter LoDuca, and the law firm must show cause for why they should not be sanctioned. “The Court is presented with an unprecedented circumstance,” Castel wrote in a previous order on May 4. “A submission filed by plaintiff’s counsel in opposition to a motion to dismiss is replete with citations to non-existent cases… Six of the submitted cases appear to be bogus judicial decisions with bogus quotes and bogus internal citations.” […] In the order issued on Friday last week, Castel said that Schwartz may be sanctioned for “the citation of non-existent cases to the Court,” “the submission to the Court of copies of non-existent judicial opinions,” and “the use of a false and fraudulent notarization.” Schwartz may also be referred to an attorney grievance committee for additional punishment. Castel wrote that LoDuca may be sanctioned “for the use of a false and fraudulent notarization in his affidavit filed on April 25, 2023.” The law firm could be sanctioned for “the citation of non-existent cases to the Court,” “the submission to the Court of copies of non-existent judicial opinions annexed to the Affidavit filed on April 25, 2023,” and “the use of a false and fraudulent notarization in the affidavit filed on April 25, 2023.”

Beating the heat: These plant-based iridescent films stay cool in the sun

Summer is almost here, bringing higher temperatures and prompting many of us to crank up the air conditioning on particularly hot days. The downside to A/C is that the units gobble up energy and can emit greenhouse gases, contributing further to global warming. Hence, there is strong interest in coming up with eco-friendly alternatives. Scientists from the University of Cambridge have developed an innovative new plant-based film that gets cooler when exposed to sunlight, making it ideal for cooling buildings or cars in the future without needing any external power source. They described their work at a recent meeting of the American Chemical Society.

The technical term for this approach is passive daytime radiative cooling (PDRC), so named because it doesn’t require an injection of energy into the system to disperse heat. The surface emits its own heat into space without being absorbed by the air or atmosphere, thereby becoming several degrees cooler than the surrounding air without needing electrical energy.

“We know there is spontaneous thermal transfer between objects with different temperatures,” Qingchen Shen said at a press conference during the meeting. Their cooling technology exploits that thermal transfer, with a twist. Most PDRC materials (paints, films, and so forth) are white, or have a mirrored finish, to achieve a broadband reflection of sunlight. Pigments or dyes interfere with that since they absorb specific wavelengths of light and only reflect certain colors, thereby transforming energy from the light into heat. The films created by Shen et al. are colored, but it is structural color in the form of nanocrystals, not due to adding pigments or dyes. So color can be added without sacrificing the passive cooling efficiency.
