Question about dual channel RAM performance
Question about dual channel RAM performance
Hello, your HP laptop has an 8GB DDR4 3200MHz RAM with a Samsung branded model. You're planning to add another RAM stick for dual-channel performance, but you're unsure whether to get the same model or a different one that matches the frequency and size.
When using dual channel, it's best to stick with matched sticks for safety. However, many users experiment with different configurations, and most still function well. If you're upgrading due to low RAM, adding more RAM is always the smarter choice, no matter the speed. Look into Kingston and Crucial's configurators to find their suggestions.
It's advised to purchase a compatible set. I've managed without matching RAM before, but others have reported problems. If you skip the matching kit and just buy another stick, aim for similar speeds—3200 MHz is ideal. Otherwise, both sticks will operate at the slower rate.
Running JEDEC standard speeds/timings is possible. You can freely combine elements as needed. This isn't about premium RAM upgrades for maximum stability.
Yes, but also no. It's generally accurate that any two sticks tend to perform similarly under JDEC conditions, even if they weren't originally matched. Ideally, a stick rated above JDEC should remain stable with others, but in practice this hasn't always happened. I've successfully used matched sticks from a kit at full speed (3600), yet when kits were mixed up, stability broke down completely.
More testing is essential yet opinions have persisted without solid evidence. In the past, issues with DDR and possibly DDR2 existed, but I believe they weren't as significant as commonly thought. Differences in timing and speed could be a factor, though others claim it runs slower than expected. Missing even numbers of RAM doesn't affect performance much. The J2C video addressed this quickly, yet many overlook RAM speed. I had to lower my RAM clock speed to make it function properly. Updated September 19, 2024 by thrasher_565
It's actually quite straightforward: with complete BIOS control, you can easily adjust timing and select kits that don't match. Performance might not hit XMP levels, but it should still function properly. Many factors influence the outcome, including CPU memory controller, RAM modules, and motherboard trace lengths. For devices like Jedec—often found in laptops or prebuilt units—make sure your components are compatible; otherwise you'll face slower speeds or issues.
