RAM - What Makes More Sense

Posted by Pilot-Candidate@reddit | buildapc | View on Reddit | 2 comments

I'm building a replacement PC and am trying to understand how to pick ram for the CPU/motherboard; the build is higher budget and aimed at gaming.

-9800x3d
-ASRock Phantom Gaming X870E Nova

I had originally figured that more speed (8000 vs 6400) would be better, then came across an article comparing a slower speed 6000/6400 vs 8000 and it came out that the 6400 outdid the 8000 in general, especially in regards to heat and power efficiency. Plus 1:1 and 2:1 stuff that is a bit past my grasp on components and theories.

tl;dr: I was looking at "TEAMGROUP Xtreem 48 GB (2 x 24 GB) DDR5-8000 CL38 Memory", but then came across stuff like this "Corsair Dominator Titanium 96 GB (2 x 48 GB) DDR5-6400 CL32 Memory". Help explain to me what I should buy, and why.

DDR5 6000 CL30/CL28 for AM5, nothing else.

If you're that adamant about wanting a <1% improvement, DDR5 6400 CL32 will beat DDR5 8000 CL38.

However, it's an extremely small difference. You're better off just getting DDR5 6000 CL30, which has the highest chance of working out of the box, and calling it a day. Ryzen doesn't benefit much from going past 6000MT/s.
