Ryzen 9 9900X and 128-192GB RAM, is it possible?

Hello AMD Community,

I am planning to purchase new Ryzen 9 9900X with Asus ProArt X870E-CREATOR WIFI or Asus ROG STRIX X870E-E GAMING WIFI.
Need to use a large amount of RAM in my work (128GB+), and its volume and overall stability of the system are more important than ultra high speed characteristics.

Will the system work with any of these memory modules?

  • G.Skill F5-5200J4040A48GX2-FX5 (Flare X5, DDR5-5200 CL40-40-40-83 1.10V, 96GB (2x48GB), AMD EXPO) x 2
  • G.Skill F5-5600J4040D48GX2-FX5 (Flare X5, DDR5-5600 CL40-40-40-89 1.25V 96GB (2x48GB) AMD EXPO) x 2

Is it even possible to combine two sets of the same memory to get a total of 192GB?
Or do I need to purchase a 128GB set of 4 modules?
Will the system work stably and how much will the memory performance decrease be (up to JEDEC instead of XMP)?

Sorry for the possibly strange questions, I also used the Intel platform for a long time and there were no particular problems with using the maximum amount of memory supported by the CPU memory controller

Need to look on Asus website for ram compatability and Amd website for Max ram supported for CPU. Combining sets of Ram is not recommended.

 AlienForever007, find the 9900X specifications here. Do an expand all to answer most of your questions. Two sets of dual channel memory sticks should work fine just keep them paired in each of the channels. I suggest you have enough power to support the memory, processor and GPU. I have always had good results with G.Skill but cannot answer concerning your specific sticks. Hopefully others will. John.

Combining kits may work, this is directly from GSkill Website.
