The board

The donor board is the current revision of the 32GB clamshell design. It ships as a 2-slot blower (turbo) card, the form factor built for stacking several cards in one workstation or server chassis.

The memory

8 additional Micron D8BZC modules are fitted alongside your original 8. Every module on the finished board is tested.

The clamshell design

The upgrade board carries memory on both faces: 8 modules on the front, 8 on the rear, sharing address and data lanes in the configuration the memory was designed for. Your original 8 modules transfer; 8 more complete the set.

The VBIOS

The card runs completely stock: stock clocks, stock power limits, stock behaviour everywhere else. No overclock is applied, nothing is pushed past specification.

Power delivery

The board's power stages carry substantial margin over the 320W the core ever asks for. The memory rail is similarly overbuilt. Nothing in this upgrade runs close to a limit.

Who this is not for

We would rather tell you now than after you have shipped a card.

  • Gamers. 16GB already covers modern games, and frame rates do not change.
  • Anyone buying a stock 4080 SUPER just to send it in. Ask us about a ready-built unit instead.
  • Anyone whose models already fit comfortably in 16GB.
  • Cards under warranty you want to keep. The upgrade replaces the board, and the manufacturer warranty does not survive that.
  • Quick turnarounds. The protocol takes the time it takes.

Still sure? Then you are exactly who we built this for.
