Hello, your recent video has definitely impacted your RAM decision. For your AMD Ryzen 5700G build, you're considering Crucial Ballistix 16 GB (2 x 8 GB) DDR4-3600 CL16. From what you've seen, single-rank memory is a key factor. It seems the Crucial model you're thinking of is indeed single-rank, which aligns with the video's emphasis. You might want to explore white-colored DRAM options for a themed build, though availability can vary. Let me know if you need more guidance!
This component is seldom advertised by manufacturers. You may discover it via reviews, though the situation gets more tricky because they produce many comparable modules with identical names or release dates but distinct differences. Generally, 8GB units are typically single-rank today, except for very old models. Some early DDR4 variants offered dual-rank options. 16GB units were dual-rank until around a year ago, after which single-rank models became common. No personal observations, but 32GB units are likely still dual-rank. You can achieve a similar setup by using two modules per channel, such as four for dual-channel. I own a Corsair Vengeance Pro 4x16GB 3200 in white, though I didn’t plan for a color scheme. It was simply available.
In the video they were using Samsung modules as an example. Samsung list more details about their module than pretty much any other manufacturer. I think in the latest video the issue they are talking about is more a problem with laptop ram for space savings than desktop memory. Depending on the design of the memory chips on the ram stick, it can affect latency by quite a bit. Having more smaller capacity memory chips on 1 stick of ram can be better than fewer larger capacity memory chips on 1 stick of ram. When your PC switches to a different memory chip on the same ram stick it saves a bit of latency, the other chip was ready waiting to be used, so it can respond faster to a request. Even though both chips can have the same speed, the difference in reaction time over time all adds up to quite a bit lower latency. Your PC keeps jumping around switching chips and saving a bit of reaction time vs waiting on the same chip to be ready for the next request. Laptops use fewer large capacity chips to save physical space. Latency is the same reason dual rank is better, your PC can switch ranks and save a bit of latency. Ranks is what desktop owners should consider Since your buying new, it's definitely recommended to get 4 total ranks, 2 per channel. The easiest way to get this is with a 4x8GB. 16GB modules are hit and miss as to whether they are dual rank, only expensive ram is guaranteed. Very cheap desktop memory can have the problem Linus was talking about in his newest video, but its pretty rare on desktop ram sticks.
Density refers to the number of chips within a given capacity, while rank describes how those chips are organized. Each group can be addressed separately, and inside each group, individual chips remain addressable. When you broaden the view, every channel stays addressable, and within each channel, each DIMM is also individually accessible. Essentially, the goal is to maximize parallel memory access. More paths mean faster storage and retrieval, but adding more DIMMs or ranks increases pressure on the CPU’s IMC. This means simply running everything at full capacity isn’t always optimal. For instance, Ryzen performs best with four ranks—either two dual-rank DIMMs or four single-rank DIMMs. The video and findings highlighted another complexity: understanding the actual composition of a rank, specifically its density, is crucial. Greater density generally improves performance, but the real impact depends on how much of a difference it makes in practice.
