Context Before

Situated at the back of the chassis, the Strata module of VR NVL72 is the equivalent of the Bianca board of GB200/300. It houses two Rubin GPUs and one Vera CPU.

Evidence

Unlike Bianca, the LPDDR5X memory for Vera is socketed via SOCAMM module.

Context After

8 SOCAMM sockets are placed on the left and right of Vera. Two SOCAMM modules of different capacities are offered, 192GByte and 128GByte, for a maximum of 1,534GByte and a minimum of 1,024GByte per Vera.

② Atomic Claim

不同於 Bianca，Vera 使用的 LPDDR5X memory 透過 SOCAMM module 以 socket 方式安裝。
