Hey folks,
With RAM prices being what they are right now, I'm wondering if saving some cash by going for a 24GB configuration (using a 16GB stick alongside an 8GB stick from the same brand with the same speed and latency) on the AM5 platform is a wise move. Could this lead to system instability, or is it generally acceptable?

Mixing RAM sticks, particularly with different capacities, can lead to stability problems. When you do this, it usually runs in flex mode rather than true dual channel. This means that while 16GB will operate in dual channel, the extra 8GB kicks in as single channel, potentially causing a performance hit when it comes into play.
It could work, but AMD's RAM compatibility can be tricky. You'd be best off using identical sticks. But if you have these lying around, it's worth a shot to see if they cooperate—just be prepared for potential headaches.
Generally, using mismatched DIMMs can introduce instability, especially at higher speeds. Some scenarios allow for stable performance at the base 4800 speed, but even then, it's not guaranteed. It's always risky to mix modules that didn't come as a kit, and there's a chance of getting different memory chips as well which complicates things further.
Definitely think twice about mixing different capacities with DDR5 RAM. It can work but it often leads to issues, especially if you plan on utilizing higher speeds. If possible, I'd recommend sticking with a matched 2x16GB kit for optimal performance.
Honestly, I wouldn’t recommend this setup. Even identical RAM sticks can sometimes cause issues, and using mismatches might lead to boot failures or worse on AMD systems due to their weaker memory controllers. If you're considering it, think about going for a single 32GB stick instead—it might save you some hassle and could be cheaper.
For anyone reading this, just know that while flex mode isn't ideal, it's still much better than running out of RAM and relying on your SSD or HDD as a page file.
