What's the Best RAM Speed and Timing for My 9800X3D?

Asked by TechieGamer99
I'm trying to figure out the best RAM configuration for my build, particularly with the 9800X3D processor. Initially, I was eyeing a 64GB kit with a speed of 6000MHz and CL30, but prices have surged recently. I want to know how much I can lower the frequency and how high I can go with the CAS latency without experiencing a significant drop in gaming performance. Should I prioritize a higher speed with slightly higher latency, or should I go for lower frequency with lower latency? Any recommendations would be greatly appreciated!

From what Iโ€™ve seen, CL30 at 6000MHz is ideal. Just a small dip to CL36 will be fine. Avoid going down to 5200MHz CL40 as that could mean an 8-15% performance drop, but this is less critical with X3D chips.

From my experience, moving from 6000MHz to 8000MHz didn't make much difference gaming-wise. Iโ€™m using 8000MHz with G.Skill RAM, and I suggest sticking around 7200MHz to 7600MHz, especially since RAM prices are all over the place right now.

I'd say stick with 6000MHz. Whether itโ€™s CL30 or CL38, it wonโ€™t impact performance much on an X3D chip. You'll be fine going either way.

Honestly, whether you go for 6400MHz CL34 or 6000MHz CL30, it shouldnโ€™t matter much in gaming. Just be cautious with those timings.
