Are both RAM models functioning correctly?
I owned a system with 32GB of RAM, featuring DDR4 3200 MHz, a link to the product page, and a photo of the setup. I also added another set of RAM two years ago, which was replaced after an RMA due to issues. The two sets are installed in four slots. I'm checking if they function properly together or if it's better to stick with the original 32GB Corsair RAM. I want to confirm CAS latency is 16 and verify all modules operate at the maximum 3200 MHz speed. Details include my specs: AMD Ryzen 7 5700x, ASRock B550 Phantom Gaming 4/AC AM4. Attached are five screenshots for reference.
I prefer using just one RAM kit rather than combining different ones. If it functions properly, I'm happy; but if instability or BSODs appear, you should check the RAM first.
I was curious about these two RAM sets—do they work well with this system that has four slots? Should I stick to the current setup or replace it with 32GB of Corsair RAM I originally had? Are the CAS latencies around 16 on these units, and are all of them capable of reaching 3200 MHz?
If you check the forums, you'll notice mixing RAM kits is generally discouraged. It's best to choose a single kit with matching sticks. Buying another Corsair kit would be risky because they only source ICs from one vendor, which affects PCB revision numbers.
Everything seems okay. You need to adjust the command rate to 2T for better stability. (1T handles 2 module setup). Also, try testing the RAM with memtest86. What kind of motherboard are you using?
The main point about RAM is you only truly understand its behavior after testing it. Either perform thorough tests yourself or purchase memory kits from a QVL list where others have evaluated the memory for your motherboard. This isn't completely guaranteed since actual chips can differ between boards and even within a single memory stick.
Ultimately, you start with something like memtest64+ and let it run overnight. You can then fine-tune the settings to improve or reduce performance until stability is achieved.
In this specific scenario, for your particular memory and motherboard, it will function optimally at certain configurations.
The general advice is to avoid mixing different types of memory. There are limited sets available from manufacturers that closely match each other's performance. Since you've invested in them, the best approach is to experiment until you find stable settings with high performance.
