Comparing Flex Mode RAM with simply skipping the third button.
Comparing Flex Mode RAM with simply skipping the third button.
I understand the concern, as many similar queries appear online. My current configuration includes a Ryzen 7 3700X with ASUS ROG Strix B550-E, 16 GB Corsair Vengeance Pro 3600MHz. I had two RAM sticks, but one was damaged, so I replaced both with identical models.
Regarding your question, you should consider whether to use 32 GB (two sticks) or 48 GB (three sticks). Running the two new sticks in dual-channel mode and the third in single-channel is a common setup. The "flex mode" you read about might offer flexibility, but it’s not ideal for heavy workloads.
Given your usage—primarily Cities Skylines and Star Citizen, both demanding a lot of RAM—the risk of performance drops with three sticks is higher than with two. Stick to the dual-channel configuration for better stability and efficiency. If you still want more capacity, you can always upgrade later. Let me know if you need further clarification!
When RAM hits the limit at 32GB, opting for three sticks is more effective. Even without enabling flex mode and operating in single-channel, the speed of RAM far surpasses that of a hard drive, improving overall performance compared to using the page file. If possible, experiment with your setup to observe the results. You already have the RAM capacity. Consider running a benchmark such as Aida64 to evaluate both configurations and verify if flex mode functions properly. Flex mode allows dual-channel operation until you reach its limit, after which it switches to single channel on the final stick. In theory, this provides the optimal balance, though real-world compatibility with your apps may vary. It's safe to try it out.
