Expanding from 16 GB to 32 GB of RAM on X570

[nathan_s]

Hi guys,

I currently have 16 GB of Crucial Ballistix Sport LT BLS2K8G4D32AESCK 3200 MHz, DDR4, DRAM, CL16. I would like to expand to 32 GB but that kit is no longer available. I am on Aorus X570 AORUS ELITE mobo.

So what is the best option, performance wise (don't mind spending more on a better option):

• Buy a "similar" one like this one: Crucial Ballistix BL2K8G32C16U4W 3200 MHz, DDR4, DRAM, Desktop Gaming Memory Kit, 16GB (8GB x2), CL16
  
  
• Buy some other 2x8 kit altogether and add to my setup
  
  
• Buy some other kit completely in a 2 x 16 setup and get rid of my existing RAM
  

Any recommendations please?

Four DIMMs would give two DIMMs and hence per rank giving command interleaving, which would boost CPU limited gaming performance.
(basically comparable to 3600 MHz single rank)
.

I can't say that I understood all of that but are you saying another set of 2x8 would be the way to go?

The more I read the more confused I am. Now thinking about buying 4 sticks of Crucial Ballistix BL2K8G36C16U4W 3600 MHz so will end up with 32GB but @3600 and the price difference is negligible (assuming I will sell my sport LT). Thinking that this may eliminate any compatibility issues. Or am I getting it completely wrong?

Some good pointers. Totally forgot about GamersNexus. Watched some videos and you're right. There won't likely to be any noticeable difference between 3200 and 3600, plus 2 vs 4 sticks is academic given that I do no plan to overclock and differences are not huge. Case closed I think.
