5 Things to Know When Mixing RAM Speeds

All sticks run at the slowest speed If you mix 3200MHz and 3600MHz RAM, the system automatically downclocks everything to 3200MHz to match the lowest stick’s JEDEC profile.

XMP or DOCP needs manual adjustment Disable XMP/DOCP to run at default 3200MHz, or manually set the speed to 3200MHz with the tighter timings from the 3600MHz kit if you’re lucky. Letting the motherboard handle it is fine—the real-world performance difference is negligible.

Match capacity per channel for dual-channel Keep matching capacity per channel (e.g., 8GB+8GB on one channel, 8GB+8GB on the other) for proper dual-channel operation. If you don’t, it still runs in flex mode.

It’s a money-saving option Mixing speeds is a perfectly fine way to save money instead of buying a full matched kit.

Don’t overthink the timings The performance difference between 3200MHz and 3600MHz is negligible in real-world use, so just let the motherboard handle the downclocking.
