I'm searching for a suitable match for my build. I have a GSkill with 32 GB, 6400 MHz, and 32-39-39-76 CAS. I'm curious if pairing it with another GSkill of 32 GB with 32-39-39-102 could cause any problems. There are two options listed:

One can be found here:
Memory Model F5-6400J3239G16GX2-TZ5RK
https://www.newegg.com/g-skill-trident-z...MjU5Mjg1OQ..

Another is available here:
Memory Model F5-6400J3239G16GA2-TZ5RK
https://www.amazon.com/dp/B09QS2K59B?ref...title&th=1

They seem very similar, except for the CAS value.

Combining memories can cause various problems. Using 100% matched memory provides the optimal outcome. A 2x32GB matched configuration is recommended.

Even with small or negligible distinctions, could conflicts still arise?

When the system starts up, it attempts to locate compatible timing with the slower components. It might succeed or fail to boot. You may need to use different tools like CPU-Z to check timings and adjust settings accordingly. Sometimes a 'cross reference' appears in JEDEC specifications. Regarding memory stability, issues can lead to gradual performance drops that resemble hardware faults.

Two modules of RAM tend to be more reliable than four, often linked to the motherboard's VRM and power delivery. Based on my experience, Intel generally handles mixed RAM better, especially on older boards, whereas Ryzen tends to be more sensitive. The outcome remains uncertain.

This can occur even without any differences, but when sticks aren't properly matched and tested together, they might not be grouped the same way. The memory controller is located in the CPU, yet all adjustments are handled through the BIOS, which may or may not recognize changes. That's why some RAMs are sold as kits and QVL lists are provided for MBs—actually for their BIOS, which is often updated to improve compatibility.
