The memories work perfectly in terms of timing and performance on an MSI Thin GF63 12VF (16R8.1) laptop. In reality, they are completely problematic due to overheating, which causes repeated reboots. If you don't immediately remove your finger from a chip that you touch, you will have a third-degree burn in your pocket. And I suspect that it will also affect battery life. Maybe there is a mistake in the construction of my laptop, but what was supposed to be done? Sell it with liquid cooling? With the 2x8GB from the manufacturer, everything is fine.
There is only one way for it to work normally. The bottom cover should be removed and have thick coolers for the SO-DIMM. I don't know if I can change them. If it's not possible, then I will have to get a new bottom cover for conversion to improve ventilation. Basically, it's a matter of taking the bull by the horns and dealing with it.
