Additional RAM

[dylsh]

Hi. I have 16GB of RAM in my machine. If I continue adding RAM, will that help with KSP and the many mods we all love to add? Or does the KSP engine only allow so much RAM to be used?

 

Thanks!

Adding RAM only helps, with any application, if you're running low.

With 16 GB, adding more will unlikely help much unless you have a ton of mods installed.  If you're not running into issues with insufficient memory, then adding more will do nothing.

How much does your KSP use?

I can’t tell how much my install is chewing up right now. I recently had to send my machine back to MSI to be fixed. But I’m a stickler for seeing the yellow colored Mission Time in the upper left of the screen. Haha. And yes, typically I have a excrements ton of mods

While adding RAM might see some improvement in load speed due to better disk caching, it will be minimal.

Past 16GB the benefit is reduced that.

The money would be better spent on moving from an HDD to an SSD, which would see great improvement, getting a video card with 6-8GB of texture memory if using a modded install, or 4GB if using a stock install or the upgrade to a processor with faster single threaded processor speed.

As of memory speed.  Dual channel DDR4 is fast enough to have the CPU be the sole bottleneck.  If you are still running single channel DDR4 or running DDR3, using high performance memory will see improvement, as will upgrading your system in a manner that allows the usage of Dual Channel DDR4. 

You can test how much memory is being used by switching out of the game while it's fully loaded (you can pause it) and looking in a system monitor utility that shows memory usage.

If you have at least 1GB between free memory and disk cache, you have enough memory for your setup.

Thank you both for your great answers. I’ve been playing KSP since 2012? 2013? And I am still astonished at how helpful and nice the community is.
