RAM Voltage

at 1.5V you definitely want some fan to blow air on the sticks or at least have some airflow there. 

 

Honestly, depends on what kind of RAM you use. 32GB sticks will put out more heat than 8GB sticks. 

You will also have more heat with 4 sticks than with 2 sticks for example.

This is a bit of a gap in my knowledge. How much do temperatures increase between 1.35v and 1.5v and what kind of cooling solution would I need to run 1.5v RAM?

Don't run 1.5v unless you actually have a need to run 1.5. I would very much not recommend that for daily use.

 

If you are trying to OC for fun and don't plan on using these settings for long, sure why not. IF you need that much voltage just to keep your day to day OC stable, drop your RAM speed....... Thats a lot of volts for day to day usage on sticks that are likely defaulted to 1.35. 1.4 is relatively safe, 1.45 is the highest I would ever recommend for daily use, and that is with directed airflow. 1.5+ really should only be for overclock runs.

 

These numbers apply to DDR4, and DDR4 only.

I think he was talking about purchasing memory that comes with an XMP profile consisting of 1.5v.

Might be wrong, it's just the way the OP is worded.....

 

 

 

Yes, I was looking at RAM with an XMP profile set at 1.5v, sorry for not clarifying.

Optimally, under 50c heavy load is where you want to be. 

Temps can increase exponentially without good case flow. 

Put fan right on the memory, and you won't have to worry about it. You can buy a memory fan kit.
