articolo che spiega bene il problema SP-CAPS/MLCC

TLDR:
Owners of cards, which still run really stable despite six solids, owe everything to the very good chip quality. Owners of cards with MLCC, where errors still occur, may be annoyed about a GPU that does not even consistently cope with the stored voltage/frequency curve. This is exactly the point where the board partners couldn’t test anything at all with the first cards due to the lack of suitable drivers. There are certainly many cards in circulation here that would not have been suitable as OC cards.
The fact that NVIDIA has split the GPU’s power supply voltages between NVVDD and MSVDD also shows that they are well aware of the problem. I noticed that the MSVDD has much less changes and is generated independently from the NVVDD, so you should be able to get along with a well equipped MLCC group. So more MLCC does no harm if the rest of the layout allows this interpretation. Without it, however, becomes slow and sluggish.
