Comparing dual rank RAM sticks to four single rank options highlights different performance characteristics.
Comparing dual rank RAM sticks to four single rank options highlights different performance characteristics.
I didn't mention anything about dual channel. The 256 bit is also in RAM, as confirmed by GN.
The 256-bit performance is limited to quad-channel only, while two dual-rank configurations offer better speed compared to a single rank.
That's all. However, finding a true 128-bit DDR4 stick isn't possible. One module typically offers 64-bit performance, whether single or dual-rank. I didn't imply that dual rank isn't advantageous, just that it doesn't make much difference. It depends on your specific needs.
Consider skipping the unused spaces for more growth (like moving to DDR5 when 32GB isn't enough). Grab 4x8GB. If you need a profile that supports memory speeds up to 4000MHz—preferably higher if possible (since Zen 3 should run at 2GHz FCLK after fixes)—then 2x16GB will be more dependable.
Thanks for the video. It looks like the results are quite comparable, though you might still achieve better outcomes with four sticks of single rank, albeit at a different configuration. I won’t be upgrading anytime soon; I suspect my setup is nearing the end of its life for AM4 and DDR4. It’s unlikely I’ll consider an upgrade until DDR5 becomes widely available and affordable. I plan to aim for a 4000MHz RAM module, but if only 3800MHz is offered, it should still suffice. I talked to a Crucial representative last night—they mentioned their 16GB sticks are available in both single and dual rank, but you can’t confirm the exact part number until you receive the package, which isn’t very reassuring. You might ask them to verify the specific model on the box, though they won’t disclose their internal selection process. My guess is it’s likely the presence of M16 rather than M8 in the packaging, which doesn’t really help when buying online. I’ll follow up with G.Skill later. As far as I understand, they offer similar options in comparable price ranges using Micron chips, so performance should be similar—just possibly a bit slower (timings 16-19-19-39 versus 16-18-18-38).
Single-rank refers to a single set of memory chips used during read or write operations. Dual-rank functions similarly by having two single-ranks on one memory stick, but only one can be accessed at once. Results can vary depending on how the software is designed to use system memory, which the OS permits. TLDR – The performance gap in gaming is minimal, making the discussion largely unnecessary.
I understand your perspective. Right now I’m not taking any action, and if I end up spending the same regardless, I’d like to maximize the results I can achieve despite the effort cost.
Relies on the context you choose for discussing performance. At 3000mhz or 3733mhz, dual rank 4 settings versus single rank 2 settings.
