Does the RAM thermal throttling occur on your PC, and is it a serious issue?
I didn’t find a review that fully answers this, but could a high-quality cooled memory improve stability rather than just system performance? Is it true that thermal throttling RAM is real and that overclocked memory is a significant topic? I’m wondering if this helps explain why strong CPU overclocks on some machines don’t always translate to better gaming or productivity results. Anyone have tested how RAM temperature affects actual system performance, especially in overclocked setups? Please let me know what you think.
The likelihood of ram overheating is very low, almost nonexistent. In fact, ram heatsinks provide minimal cooling, and even RGB lighting isn't sufficient to cause significant thermal throttling. Changing the PC's overclocking settings won't impact ram performance; however, other problems like stability issues will appear long before overheating occurs. You'd need to push maximum overclocks with extremely high voltage, which still risks damaging the ram through over-voltage.

In reality, RAM cooling fins offer minimal assistance, and even RGB lighting doesn't create significant enough thermal problems to cause throttling. Changing the PC's settings won't impact the RAM; adjusting RAM settings does affect performance, but you'll encounter stability problems long before overheating occurs. Pushing maximum settings with high voltage could damage the system, and even then, it wouldn't prevent the RAM from failing due to excessive heat.
RAM doesn't naturally dissipate heat through the air (which is why heatsinks are mostly just for show). It releases heat into the motherboard's ground plane. If you manage to approach thermal throttling, the amount of heat being sent to the board will be extremely high, leading to additional complications beyond just overheating the RAM.
The temperature thresholds for both RAM and VRAM are well above 100°C (roughly), so it's important to calculate how much heat each component generates over time. For typical setups, running LN² behaves differently since it involves frequent BCLK adjustments, which influence bus speeds and consequently the internal speeds of the RAM and memory controller.
Micron memory operating temp details:
TC max up to 95C
64ms, 8192-cycle refresh up to 85C
32ms, 8192-cycle refresh at >85C to 95C
These temperatures haven't been widely reported. Memory usually becomes unstable and causes crashes long before reaching them. It either functions properly or fails completely.

Also worth noting, overclocking in a stable environment can make a small temperature difference crucial, especially with B-die configurations.
