Circuit Board (PCB) Analysis

GPU voltage is handled by a 6-phase VRM driven by a UPI uP9512R controller.


Alpha & Omega Semiconductor BLN3-AOZ5311NQI DrMOS are used for the GPU power phases, these are each capable of 55 A.


A single-phase buck controller handles memory voltage.


For memory, Galax is using a set of Sinotech ON3103 and ON3107 discrete MOSFETs rated for 64 A.


The GDDR6 memory chips are made by Samsung and carry the model number K4ZAF325BC-SC20. They are specified to run at 2500 MHz (20 Gbps
effective).


NVIDIA's AD106 graphics processor is the company's fourth Ada Lovelace GPU. It is built using a 5 nanometer process at TSMC Taiwan, with a transistor count of 22.9 billion and a die size of 190 mm².
