Intel’s memory controller operates at either 100 or 133 MHz, producing multiples of 200 or 266.6MHz at integer ratios.The easiest way to exceed DDR4-2666 on any of this hardware is to use a Z-series (Z390, Z370, Z270) chipset with a K-series Core i5 or higher processor. We also experienced a firmware locking out ratios higher than DDR4-2400 when using a Core i3-8350K on the Z370 we used as a baseline in in our initial H370/B360 roundup. Intel’s LGA 1151 processors have memory controllers that are stable well beyond DDR4-3600, but the firm figured out a way to get non-Z-series chipsets to instruct any CPU (even a K-series) to lock out higher ratios.If you’re using a lower-model processor or anything less than an X470 motherboard, we recommend reading other user’s findings before buying anything faster than DDR4-2933. Earlier Ryzen 2000-series processors could typically accept at least DDR4-3467 without crashing, but higher frequencies induce noise (often in the form of signal cross-talk), and the pathways between the CPU socket and DIMMs of some boards weren’t up to the task.Our initial review of G.Skill’s Trident Z RGB DDR4-3600 showed that performance dropped when setting DDR4-3733 as AMD’s default controller limitations reduced those ratios, but a retest showed that performance improved at DDR4-3733 when those limits were disabled.

Organized in rows and columns of cells in a similar manner to a spreadsheet (or very large table), Random Access Memory is able to access any of those cells in whatever order is instructed by the memory controller. SDRAM stands for Synchronous Dynamic Random-Access Memory.Some compact desktop boards use SODIMMs, typically (but not exclusively) to make room for four modules on a motherboard design that might otherwise only support two. DIMM stands for dual inline memory module: Today’s DIMMs have two 64-bit interfaces, one on each side, and are generally sold as either UDIMMs (aka DIMMs, long DIMMs, etc) for desktop or SODIMMs (small outline DIMMs) for notebooks.
But unless you’re working with a system that’s several years old at this point, you’ll probably be dealing with DDR4. Most of the terms we’re using today also apply to previous generations of memory. We’ll focus today on DDR4 because that’s where the industry has standardized over the last four or five years.
