GALAX did not expedite the development of a flagship GeForce RTX 5090D custom design; as evidenced by the absence of a top-flight Hall of Fame (HOF) option during launch week. "Cheaper" options—in the form of General and 1-Click models—were made available to the Chinese public on January 30. GALAX's fanciest new-gen "Blackwell" HOF model debuted with less potent hardware onboard: GeForce RTX 5080 OC LAB Plus-X Edition. Throughout early 2025, GALAX seeded early samples—of HOF GeForce RTX 5090D hardware—with tenured extreme overclocking organizations. Last month, almost finalized board designs became record breakers—achieved via liquid nitrogen cooled methodologies. Earlier prototypes sported a single 16-pin power connector, but newer Extreme Overclock (XOC) iterations were distributed with a second power delivery channel.

Yesterday, GALAX's social media channel teased the imminent launch of their air-cooled retail variant: "5090D HOF XOC Edition (Limited). Seems like it will be on China market soon…" Up until very recently, overclocking champions have shared photos of bare GALAX GeForce 5090D HOF cards—industry watchdogs reckoned that company engineers were still realizing a next-gen cooling solution. The Chinese manufacturer's promo material advertises the (presumably) very expensive forthcoming SKU as an option "only for better performance." Product renders showcase a familiar (optional) crown-adorned shroud, but it is not clear whether GALAX has revised its backplate design for this generation's XOC flagship.

GALAX unveiled its Boomstar series graphics card, introducing two RTX 5090D variants, LUNA and NOX, exclusively for the Chinese market. Both models share identical specifications, differing only in aesthetics: LUNA sports an all-white finish, while NOX adopts a matte black look. At the heart of each Boomstar card lies NVIDIA's GeForce RTX 5090D GPU, factory-overclocked to a 2,452 MHz boost clock, up from the reference 2,407 MHz. Power delivery is handled by a robust 16+6+7 phase VRM on a 14-layer PCB, with the card's total thermal design power rated at 575 W. GALAX recommends pairing the Boomstar series with a 1,000 W power supply, utilizing the latest 12 V-2×6-pin connector standard to ensure stability under full load. Display connectivity comprises three DisplayPort 2.1b outputs alongside a single HDMI 2.1b port, enabling multi-monitor and high-refresh-rate setups.

Measuring 348 × 155 × 60 mm (including bracket), the triple-slot, triple-fan cooler departs from conventional designs by employing magnetic attachments for both shroud and backplate. This tool-free system allows users to lift off the entire fan assembly without screws or cables, simplifying dust removal and maintenance. GALAX confirms that detaching these magnetized components does not void the warranty, although it cautions against removal while the card is operational. Out of the box, each card includes one customizable magnetic sticker, part of Boomstar's signature interchangeable panel concept. GALAX has yet to clarify whether additional sticker packs will be sold separately. GALAX has not disclosed pricing or availability timelines but confirms that Boomstar LUNA and NOX will remain confined to China, with no non-D variant planned for other regions.

Lenovo has listed two custom Legion GPUs designed specifically for its Legion 9000K gaming systems. These models—the RTX 5090D and RTX 5080—are available exclusively in the Chinese market and are not intended for the DIY segment. The "D" designation in the RTX 5090D model signifies that the component adheres to specific regulatory standards required in China, hence Lenovo choosing it for their China-exclusive systems. Both GPUs incorporate a cooling solution that spans four expansion slots and utilizes three fans, complemented by CNC-machined metal shrouds and full backplates. While detailed parameters such as core and memory clock speeds have not been disclosed, the two models differ in their GPU architectures: the RTX 5090D is built around the larger GB202 die, and the RTX 5080 uses the smaller GB203 silicon.

Both cards employ a single 16-pin power connector and are expected to operate at standard factory settings without factory overclocking dialed in yet. But with a massive cooler configuration, it should be an easy thing to do. Regarding computational capability, the RTX 5090D delivers up to 2,375 TOPS, supporting gaming tasks and localized AI processing. These GPUs are integrated within systems powered by Intel's Core Ultra 200K series processors. System configurations start at 22,499 RMB (approximately $3,100) for units featuring the RTX 5080 paired with a Core Ultra 7 265K processor and 32 GB of RAM. In contrast, configurations with the RTX 5090D, Core Ultra 9 285K processor, and 64 GB of RAM are priced at 41,999 RMB (roughly $5,820). Lenovo has also indicated that mid-range RTX 5070 variants are planned for future releases and that final production units may vary slightly from the initial promotional renders of these cards.

A formerly dormant member of China's Chiphell discussion board has resurfaced with a major GALAX leak; they claimed ownership of a pre-release GeForce RTX 5090D HOF OC LAB edition graphics card. The Hong Kong-based AIB did not update its "Hall of Fame" series with flagship NVIDIA "Blackwell" GPU silicon in time for last month's launch. Their highest-end offering arrived in the form of a GeForce RTX 5080 HOF OC LAB Plus-X SKU; reportedly an over-specced juggernaut. According to the latest reports, GALAX's top GeForce RTX 5090D candidate is in the pipeline—early details indicate an impressive feature set. The manufacturer is well known for its selective methodology; GPU industry watchdogs believe that the incoming flagship utilizes only the very best pre-binned GB202 GPU dies and GDDR7 memory modules.

Despite a fitting of elite-tier parts, the lucky owner reported issues with their allegedly sanction box-ticking card: "this time the overclocking was more troublesome. The bracket and backplate of the graphics card gun had to be remade. Finally, it was done. I won't say more. I'm going to fill it with liquid nitrogen." VideoCardz believes that GALAX has sent preview samples to local overclocking specialists, minus finalized air-cooled solution attachments. As disclosed by the Chiphell member
(laoshu1919), early evaluators appear to be experimenting with liquid cooling. A photo of GALAX's GeForce RTX 5090D HOF OC LAB PCB design was shared on the forum; showing a grand total of 38 high-quality power phases. The GPU die is surrounded by 26 of these units, while 10 are positioned closer to the card's VRAM. Another 2 are located nearby to a single 16-pin power connector, with enough extra room to accommodate two more. Judging from laoshu1919's photo, this prototype seems capable of hosting another 16-pin power connector. The sample's I/O bracket likely sports GALAX's signature "1-Click OC" button.

Unlucky owners of problematic GeForce RTX 5090 and RTX 5080 graphics cards have posted feedback across various online community sites. Press outlets started to take notice of these documented issues soon after the launch of NVIDIA's debut wave of "Blackwell" GPUs. PC Gamer has "kept track" of reports relating to black screens and miscellaneous failures—the site published an investigative article late last week, following user feedback "hitting critical mass" across Reddit and Team Green's own forum. A request for comment was sent over to NVIDIA HQ; PC Gamer received a brief response. A company spokesperson confirmed that their team is: "investigating the reported issues with the RTX 50-series."

Several PC hardware community members have documented their troubleshooting experiences—the most common suggestion involves downshifting from a PCIe 5.0 connection to 4.0, on the PEG-16 graphics port. Unfortunately, this step did not resolve black screen issues for certain owners—a member of the buildapc subreddit explored a wide array of troubleshooting channels. They re-installed Windows 11 (23H2), adjusted BIOS settings, experimented with monitor connections, and played around with drivers. Best results were produced by connecting a single monitor to their MSI GeForce RTX 5090 GAMING TRIO OC's DisplayPort, with nothing else hooked up to the other ports (DP and HDMI). They suspect that Team Green's GPU drivers could be the source of frustrations; corroborated by a recent VideoCardz news piece. In addition, the 572.16 driver is reportedly affecting "certain GeForce RTX 40-series." A smaller number of owners have discussed a "bricking" of cards; VideoCardz believes that China-exclusive GeForce RTX 5090D models are suffering the most. Manli will be analyzing a "bricked" unit at its service center, in the near future. Colorful did not reply with a comment on the situation.

A South Korea-based hardware enthusiast—Harukaze5719—has discovered a curious listing of ZOTAC's GeForce RTX 5090 SOLID OC model on a Chinese auction site (asking price: ~$4175 USD). This finding was shared with their audience, via a social media post—a screenshot was accompanied by harukaze5719's short and succinct message: "OMG..." Officially, NVIDIA and its board partners cater to the Chinese hardware market with a restricted variant of the flagship "Blackwell" GPU—GeForce RTX 5090D. Despite under-the-hood nerfing, this region-exclusive model still offers enviable performance (when pushed).

The "full fat" GeForce RTX 5090 GPU appears to be an even hotter commodity—with demand (at launch) exceeding far exceeding supply. ZOTAC's South Korean branch warned potential customers about difficult conditions almost two weeks ahead of Blackwell's market debut on January 30. Harukaze5719 has likely expressed semi-personal frustration over apparent South Korea market-destined ZOTAC stock turning up for sale in China. So-called "Chinese GPU shopping tourists" could have made the journey to a South Korean PC hardware store, with their sole objective being the acquisition of GeForce RTX 5090 graphics cards. Tom's Hardware has gathered various related tidbits from Japanese and Taiwanese news sources—where local TV coverage explored the events of last week's launch event.

Late last month, NVIDIA claimed that 16-pin power connector issues were a thing of the past. The controversial 12VHPWR connection standard has fueled many online debates—prompting investigations from several prominent press outlets. Following NVIDIA's latest "safety" declaration—likely by coincidence—PCM Hong Kong reported another melting incident, affecting two cables and a power supply unit. The publication's hardware reviewer was recently engaged in the "full-load" testing of GeForce RTX 5090D and RTX 5080 graphics cards. Last week's evaluation session was interrupted by notable test system instabilities—upon downing tools, the PCM staffer discovered that their 1200 W PSU had given up the ghost. Additionally, two 16-pin cables had melted at both ends—initial detective work pointed to a GeForce RTX 4090 sample card being the main culprit.

VideoCardz and UNIKO's Hardware kept close tabs on PCM's next steps—online interactions, over the past weekend, spurred a re-evaluation of circumstances. According to PCM's latest update, they noticed burn marks on the GeForce RTX 4090 test unit—the two GeForce RTX-50-series cards did not exhibit any physical damage. Post-analysis, the reviewer now suspects that an SSD failure could be the root cause. They were happy to report that all involved RTX cards have survived, and that their test platform has been re-equipped with 12V-2x6 cables. An amended VideoCardz article proposes that everything came down to a simple human error.

According to widespread user reports from Chinese tech forums and Reddit communities, multiple RTX 5090 and 5090D graphics cards are failing permanently after standard driver installation. The issue affects both the standard RTX 5090 and the export-modified 5090D variant released for the Chinese market on January 30th. Users report consistent failure patterns: upon initial driver installation, displays go dark, and systems permanently lose the ability to detect the GPU through both DisplayPort and HDMI interfaces. Hardware failures have been documented across multiple board partners, with Colorful, Manli, and Gigabyte cards showing identical symptoms. Third-party vendor reports sometimes indicate potential IC burn damage, suggesting hardware-level failure rather than recoverable software issues.

Some investigations point to PCIe Gen 5 implementation as a possible root cause. The RTX 5090 series represents NVIDIA's first fully Gen 5-compliant GPU architecture, introducing new signal integrity challenges. Some users report temporary mitigation by forcing PCIe 4.0 mode in BIOS settings, though this workaround remains unverified. Additional complications arise from modern motherboard designs that share PCIe lanes between M.2 storage and graphics slots. The failure pattern appears consistent across both domestic and international markets. On r/ASUS, users report identical detection failures persisting through CMOS resets and system rebuilds. Chinese forum documentation shows systematic failures across multiple board partner implementations, suggesting a fundamental architecture or driver compatibility issue rather than isolated manufacturing defects. NVIDIA has not issued official guidance on the failures.Below are screenshots of the reported user problems:

Yes, the title is correct. One of NVIDIA's GeForce RTX 5090D "China" edition GPUs, not the regular RTX 5090, managed to run at 3.4 GHz under liquid nitrogen. With a staggering 575 W default TDP, Tony Yu, ASUS China's general manager, has performed physical modifications that allow the card to run up to 1000 W TDP. The RTX 5090D is a China-exclusive variant with virtually no difference from the regular RTX 5090, just limited general AI capability due to US export regulations. ASUS China used its top-end Astral OC variant for this stunt, which, as we proved in our review of the regular ASUS RTX 5090 Astral OC, has some pretty good chip binning, allowing the card to reach the highest overclock. We pushed the regular RTX 5090 Astral OC GPU on air to 3086 MHz, a +277 MHz over the stock boost setting. However, the RTX 5090D equivalent under LN2 manages to reach 3,390 MHz at peak loads, which is a +581 MHz difference.

For memory, the overclock is equally impressive with 34 Gbps. Regarding performance, the LN2-overclocked RTX 5090D surpassed stock performance by approximately 16%. During benchmark tests, the GPU outperformed multiple previous-generation graphics cards, including a dual RTX 3090 Ti configuration in Port Royal and a quad GTX 1080 Ti setup in Fire Strike. Power consumption figures indicate that 1,760 W was used in total for a rig with ASUS ROG Astral RTX 5090D, which is paired with the Ryzen 7 9800X3D on the ASUS ROG X870E Hero motherboard. This roughly yields a 1,000 W power consumption by the card, which has seen its PCB get physical modifications to output such high power.

NVIDIA's upcoming GeForce RTX 50-series is expected to make a debut during the CES 2025 show in January. However, NVIDIA serves a lot of markets, and its significant presence is also recorded in the Chinese market as well. Hence, the company has prepared its "Dragon" version of the top-of-the-line GPU versions for Chinese gamers, complying with export regulations that forbid Chinese entities from acquiring GPUs powerful enough to train AI models. NVIDIA appears to be developing "D" variants for both RTX 5090 and RTX 5080 cards, but we only have the confirmation for the GeForce RTX 5090D so far, thanks to MEGAsizeGPU. However, a new leak from the Chinese Chiphell forum points to RTX5090D having the same hardware specification as the regular RTX 5090.

In the last generation, RTX 4090 and RTX 4090D were different, with the RTX 4090D having lower TGP and core count. However, this time around, NVIDIA will physically leave the same expected GB202 "Blackwell" die with CUDA core count and memory, only to lock certain features through firmware. Since the primary goal of export regulations the US is imposing is slowing down Chinese access to GPUs powerful enough to train and inference AI models, we expect to see the RTX 5090D with reduced Tensor core capability and maybe a lowered frequency of the overall chip. This could limit some applications from using these Tensor cores for inference, while NVIDIA's AI features like DLSS could also be a bit slowed down. NVIDIA may find a way to allow DLSS and other gaming-related technologies to operate normally while other general-purpose AI tasks are limited. Readers may recall Low Hash Rate (LHR) cards during the crypto mining boom, which had a similar firmware lock to cap mining hash rate.
