HELP NEEDED: Uncorrectable ECC memory error

JUST BOUGHT TWO NVIDIA A100-PCIE-40GB. One of the two says ‘DRAM Uncorrectable: 47’ and does not run.
Is this a hardware problem? If it is a permanent damage I guess I can have the unit replaced since I just bought it. I read that one has to reset the unit but I don’t want to do it if it involves loosing memory banks or any limitation to my brand new unit.

I would try to replace the GPU

Thanks.
