Upgrading from 64GB to 128GB Memory

[eyeangle]

I'm thinking of upgrading from 64GB to 128GB Memory. I checked the manual of my Motherboard (Gigabyte B550 AORUS ELITE AX), and this is what is says under memory:

 

- 4 x DDR4 DIMM sockets supporting up to 128 GB (32 GB single DIMM capacity) of system memory.

- Support for DDR4 3200/2933/2667/2400/2133 MHz memory modules.

 

Then I ran CPU-Z and my current Corsair memory is running at a frequency of 1066MHz. (4x16GB modules).

 

The manual doesn't say anything about supporting 1066MHz which it's currently doing, so would I notice a difference upgrading to 128GB 3200MHz? I use my PC for 4K video editing in DaVinci Resolve and occasional gaming.

That's because DDR is Double Data Rate, so two DIMMs is 1066x2=2132 (roughly, 2133). That's JEDEC speeds and XMP is not enabled on this memory kit.

A clock speed of 1066 MHz is equal to 2133 MT/s which is marketed as 2133 MHz (DDR = dual data rate, two transfers per clock cycle).

 

Having more or faster memory will only help if the RAM is the limiting component in your machine. Otherwise you'll likely not see much benefit and would be better of upgrading anything else.

Thank you (both) so much for clearing that up for me.
