At 1.5V it’s important to have a fan moving air across the memory modules. This depends on the RAM type you’re using. Larger modules like 32GB generate more heat compared to smaller ones such as 8GB, and having multiple modules—like four instead of two—adds extra heat.
Avoid running at 1.5v unless you truly require it. It’s not advisable for regular use. For casual overclocking, just stick with what you have—don’t push beyond what your hardware can handle. If you need more power just to maintain stability, lower your RAM speed instead. These voltages are quite high for everyday operation on chips that usually default to 1.35. A 1.4 setting is fairly safe, while 1.45 is best for short-term use with proper cooling. 1.5 or higher is mainly for extreme overclocking and applies only to DDR4 memory.
He seemed to refer to buying memory paired with an XMP profile at 1.5v. That might not be accurate—it could just reflect how the original poster phrased it.
Ideally, aim for a lightweight setup around 50 cents under heavy load. Without proper heat dissipation, temperatures can rise rapidly. Place the fan directly on the memory module and you’ll avoid extra effort. Consider purchasing a dedicated memory fan kit.
