VideoCardz reports overclockers are already playing with the yet-to-be-introduced MSI GeForce RTX 2080 Ti Lightning Z video card. Expected to be introduced at CES, this model features 19-phase VRM and three 8-pin PCIe power connectors. The PCB is designed for overclocking on LN2. It has various fan and voltage connectors on the right side, which is covered by its own heat plate with a heatpipe.
Various entries can be found on the HWBOT website, showing LN2 overclocking sessions in excess of 2450MHz. Photos of the PCB can be found online but so far there are no pics of the card's cooler.
