While playing Red Dead Redemption 2, my Kingston DDR4 temp readings jump from 60℃ to 80℃ instantly. Is the sensor broken or do I need a replacement?

I went through a classic misdiagnosis here. I thought the RAM was actually overheating, so I slapped on heatsinks, but it did absolutely nothing. In test environment 2026-07-F, I went into the monitoring software settings and switched the sensor mode from 'Fast' to 'Precise'. I discovered the motherboard sensor interface was picking up interference under heavy load. I tried disabling power-saving states in the BIOS Advanced Power Management to force a stable voltage to the memory controller. Under GamePP, RAM usage stayed between 6.2GB - 6.8GB, and temps finally leveled out at 64℃ - 67℃. It fixed the jumping, but my idle power draw went up by 5W, which might be a dealbreaker for laptop users.
