MSI RTX 5090 Lightning Z OCER Breaks LN2 Records Ahead of CES 2026 Reveal

MSI teases a January 5 reveal following PCB leaks plus community benchmark posts.

Overview

  • New overclocking runs pushed the GPU to roughly 3.75 GHz under LN2, edging past a prior 3.65 GHz mark, with GDDR7 tuned to 36 Gbps.
  • Wccftech reports an XOC BIOS power limit up to 2,500W, topping ASUS’s 2,000W figure, with these settings intended for extreme benchmarking rather than typical use.
  • Leaked PCB photos show a 40-phase power design and Lightning branding, while reports conflict on dual 16-pin versus dual 12V-2x6 connectors, which remain unconfirmed.
  • Multiple HWBot and 3DMark submissions that reference an MSI GeForce RTX 5090 Lightning claim first-place results across tests, including new high Time Spy scores.
  • Overclocker commentary indicates the OCER units are non-retail samples with bare heatsinks for LN2 sessions, leaving retail specifications and performance to be clarified at CES.
