Yes, you can maintain dual-channel performance at the same speed and latency even if the capacity differs slightly.

I own an Asus M570DD (X570DD Software Reported) laptop. I purchased a stick from the same brand, with identical speed and CPU latency (Micron/Crucial), but it doesn’t match the original capacity. Could my machine actually support dual channel or similar technology? I’ve researched this subject extensively yet still haven’t found any suitable options for laptops. Since I can’t open the device myself (lacking certain tools), I’m taking it to a technician who told me it won’t work. I’m curious what others think...
Specifications: CPU – Ryzen 5 3500U, GPU – GTX 1050, Mobile RAM – 4GB, 1x Micron 8GB DDR4-2666 CL19 (per CPU-Z), Pre-installed Storage – 256 GB NVMe SSD. The stick I’ll install is a Crucial (Micron brand) 4GB DDR4-2666 CL19 at 1.2V. Thanks in advance!
Edited December 31, 2020 by GorujoCY – It was CL19
It operates on dual channels until the 4GB drive is full. Consider purchasing an 8GB stick for better performance.
yeah if I don't see a significant improvement in gaming or other workloads, I'll return the 4gb stick and get an 8Gb identical specs stick from crucial Edited December 31, 2020 by GorujoCY Spelling mistake
You wont know until you try unfortunately, in the past i mixed up a lot of different ram together, different speeds, different brands, different capacities, sometimes it worked some times it didn't. Just like the name implies its volatile, and quite honestly finicky. While it should work, there's no definitely it will work as this is ram we are talking about, i'm sorry but nobody can guarantee you with a straight face that its going to 100% work, like Prodigy said though even if it does work once you hit that 4 GB threshold it might have a performance impact though if you ask me i think its going to be negligible.
