TLDR
- SK Hynix has begun mass production of its 192GB SOCAMM2 memory module, built for Nvidia’s upcoming Vera Rubin AI platform.
- HXSCL stock rose 3.4% in the Korean session on the news; Nvidia (NVDA) was down about 1.4% in pre-market trading.
- The SOCAMM2 is designed to cut power use and eliminate memory bottlenecks in AI model training and inference.
- Vera Rubin is set to succeed Nvidia’s Blackwell line, with initial shipments expected in the second half of 2026.
- Bernstein analyst David Dai called Vera Rubin “a monster,” projecting up to 5x better inference performance and 3.5x faster training than current models.
SK Hynix, one of the world’s largest memory chip makers, confirmed Monday it has started mass production of the 192GB SOCAMM2 — a next-generation memory module built specifically for Nvidia’s Vera Rubin AI platform.

The announcement pushed SK Hynix stock up 3.4% in Seoul trading. Rival Samsung shed 1% on the same day. NVDA was trading around 1.4% lower in pre-market hours, though that move appeared unrelated to the announcement.
The SOCAMM2 is not a minor spec bump. SK Hynix says the module is engineered to run AI servers at lower power consumption while tackling the memory bottlenecks that slow down both training and inference of large language models.
That’s a direct pitch to Nvidia’s core data center market, where power efficiency is increasingly a top selling point for customers building out AI infrastructure.
What Is Vera Rubin?
Nvidia unveiled its Vera Rubin platform earlier this year as the follow-up to its Blackwell processor line. First shipments are expected to start in the second half of 2026, though recent reports have flagged potential delays tied to capacity constraints at key suppliers.
Bernstein analyst David Dai described Vera Rubin as “a monster,” projecting up to 5x higher inference performance and 3.5x faster training compared to current-generation models. Those are the kinds of numbers that get data center buyers paying attention.
SK Hynix starting mass production now is a meaningful signal that the supply chain is moving in the right direction for an on-time launch.
The KOSPI index rose about 1% on Monday, partly lifted by the SK Hynix gains.
SK Hynix’s Position in the AI Supply Chain
SK Hynix is a key supplier of advanced memory to Nvidia. Its products — including high-bandwidth memory (HBM) used in AI accelerators — have made it one of the biggest beneficiaries of the AI infrastructure build-out.
The company also supplies memory components to Apple, among others, giving it broad exposure across the technology sector.
Samsung, its closest competitor in the advanced memory space, has been working to catch up in HBM production but has faced qualification hurdles with Nvidia. Monday’s 1% drop for Samsung stands in contrast to the Hynix rally.
According to TipRanks, NVDA stock carries a Strong Buy consensus rating based on 41 Buy ratings, one Hold, and one Sell over the past three months. The average price target of $237.57 implies roughly 35.6% upside from current levels.
SK Hynix rose 2.1% in one data point and 3.4% in another cited by different reports — the spread likely reflects intraday movement versus the session close.
