SK Hynix has quietly prepared four new DDR5 chips capable of reaching native speeds of 7200 MT/s, surpassing the current JEDEC standard of 6400 MT/s. Spotted on Chinese e-commerce platform JD, these chips include 2Gb B-Die and 4Gb M-Die variants alongside previously reported A-Die and C-Die options—expanding high-speed DDR5 availability across multiple capacity tiers.

Four Dies, Same Blazing Speed
SK Hynix has developed chips with capacities ranging from 2Gb to 4Gb, all featuring the “KB” designation that indicates 7200 MT/s native speed. The lineup includes the previously reported 3Gb A-Die alongside three newly spotted variants: 2Gb B-Die, 2Gb C-Die, and 4Gb M-Die.
Particularly noteworthy is the 2Gb B-Die—a configuration never before seen in SK Hynix’s lineup—and the 4Gb M-Die, representing the first example of this process node at that capacity. This diverse range allows manufacturers to balance speed versus density depending on use cases.
PCB Requirements for Stability
High-speed 7200 MT/s DDR5 modules will require at least 10-layer or 12-layer PCBs to sustain these speeds, particularly when overclocked. The initial samples spotted may use simpler PCB designs, but expect higher-layer boards soon for better signal integrity and overclocking headroom beyond 8000 MT/s.
This aligns with Intel’s platform roadmap—Panther Lake CPUs (late 2025) and Arrow Lake Refresh (2026) are expected to support DDR5-7200, representing a significant leap from Raptor Lake’s DDR5-5600 and current Arrow Lake’s DDR5-6400 standards.

Already in Production
SK Hynix hasn’t officially announced the availability of these 7200 MT/s memory chips, but their presence on JD confirms production is already underway. This quiet rollout is common in the memory industry, where products are often tested through select distribution channels before global launches.
The expansion beyond A-Die demonstrates SK Hynix’s commitment to high-speed DDR5 across multiple price and performance tiers, ensuring manufacturers can build everything from enthusiast overclocking kits to mainstream high-performance modules.
FAQs
When will 7200 MT/s DDR5 memory be widely available?
Production is underway, with broader availability expected alongside Intel Panther Lake and Arrow Lake Refresh launches in 2025-2026.
Which SK Hynix die is best for overclocking?
The 3Gb A-Die remains the preferred choice for extreme overclocking, with proven headroom beyond 8000 MT/s.
