Looking for the fastest Intel DDR5 64GB (2X32GB) memory

[guruabyss]

I've been looking for the fastest DDR5 64GB (2X32GB, putting in max mem of 128gb) memory and all that I've found so far is the:

G.SKILL Trident Z5 RGB Series (Intel XMP 3.0) DDR5 RAM 64GB (2x32GB) 6800MT/s CL34-45-45-108 1.40V (Model: F5-6800J3445G32GX2-TZ5RK)

Are there faster options or is that brand/model it? Any advice would be much appreciated!

1. Because they’re not sold to be combined. Once you combine them, the frequency, voltage and timings binned by the memory vendor are no longer valid.

Let’s put it this way; The memory is overclocked once EXPO/XMP is applied, how is any controlling party (CPU, memory or board vendor) supposed to know if the DIMMs will still be stable when you enable XMP? 

F5-6800J3446F48GX2-TZ5RK is fine. As you’re looking for memory for an unreleased board only so much one can say. 14th gen CPUs likely have stronger memory controllers, but all the above still applies. As max validation states 8000MT, any 48GB kits in the region of 7200-7600 should be your aim if looking for best chance of plug and play.

@Shinchan0125 Is the "DOMINATOR® TITANIUM First Edition 64GB (2x32GB) DDR5 DRAM 6000MT/s CL40-40-40-77 1.1v" faster than the G.SKILL Trident Z5 RGB Series (Intel XMP 3.0) DDR5 RAM 64GB (2x32GB) 6800MT/s CL34-45-45-108 1.40V?

G.Skill is faster with lower latency.

Agree, when I used to make adjustments with DDR4 memory, I calculated effective speed by dividing the RAM speed by the CAS latency. It's a simplification, but all things being equal, the 6,000MT/s kit has an effective speed of 150 while the 6800MT's kit has an effective speed of 200. I believe this still holds true for DDR5, so it's about 33% faster overall.
