128GB RAM but build mentions only 64GB #2

Closed likewise closed 4 years ago

Hello,

I was searching how to support 128GB with Ryzen 3900x, because many motherboards do not support 4 slots at high DDR speed, only 2 slots.

In your title is says 128GB but in your build I think you mention 2x32GB = 64 GB.

Can you please elaborate this?

The column Count has the value 2. In other words two of these https://www.corsair.com/us/en/Categories/Products/Memory/VENGEANCE-LPX/p/CMK64GX4M2E3200C16

Total RAM is = 2 2 32 GB = 128 GB

I don't have access to the computer right now so I can't check the DDR speed, but I remember that

cat /proc/meminfo | grep MemTotal

showed that it had 128 GB.

Thank you. If I am not mistaken, ASUS does not mention a QVL for 128GB in 4x32GB configuration:

This is the reason I chose for i7-10700K + 4x32GB DDR4-3600 for one of my builds, whereas my preference was slightly for 3900x. (Although my main application is single-threaded).

Thanks for sharing your build.
