Product Information

Hier erhält man natürlich für den Preis auch keinen ausgefallenen Kühlkörper oder sogar RGB-Beleuchtung, sondern ganz klassische grüne Riegel die optisch nicht viel leisten. Each dual inline memory module (DIMM) has two 64-bit interfaces (one on each side) connected in series. Each interface supports one rank of memory, so that a single-sided module usually has one filled rank, and a double-sided module usually has both ranks filled. (Caveat alert: Though less common, some memory has through-paths, or “vias,” that connect both sides to a single interface.) Since the two sides of a dual-rank module are connected in series, one might not expect the added rank of memory ICs (integrated circuits, i.e. “chips”) to improve performance. This is where interleaving comes into play. Interleaving allows two different operations to occur simultaneously, such as accessing data on one rank while transferring data on the other.

It may be an Intel technology, but enthusiast-class AMD motherboards are also designed to support XMP. As motherboards are often programmed to slightly alter certain timings to further stabilize AMD’s different memory controllers, motherboard manufacturers have occasionally applied their own names to this setting, such as Asus and its D.O.C.P.Moreover, most of that gain can simply be achieved by moving from one rank per channel to two, something that you might accomplish by simply adding another two matched-spec modules to a machine that has two empty slots. So bear that in mind as you shop the sales. This is where we start to get into the geeky stuff. Let’s start with the short answer: While a higher data rate usually has a greater impact on measured performance, optimally “timed” memory kits such as DDR4-3200 CAS 14 can often outperform poorly timed kits such as DDR4-3600 CAS 20—despite the optimized kit’s lower data rate. (More about what “CAS” is in a moment.) Even though these two are completely different platforms, both support DDR4-3600 at a synchronized FCLK. AMD recommended DDR4-3200 at the time of the launch of the Ryzen 3000 Series, and buyers who can’t afford DDR4-3600 at reasonable timings (CAS 18 or lower) might wish to consider this less-expensive option. ▶ Intel Z390, H370, B360, and Z370 Chipset Motherboards (With 8th and 9th Generation CPUs) When it comes to a PC component as opaque as system memory, the idea of value-for-money often gets put aside when considering the “best” choice for a performance machine. But there’s a big statement that should be made here: Most programs see very little gain from high-performance memory with elite specs, and even the most memory-impacted programs we’ve used have showed less than 6% performance gain in going from ordinary DDR4 to an optimized configuration.

But that long familiarity we have with DDR4 doesn’t make memory upgrades today any less complex. How do you go about buying the best memory configuration for your PC? Whether you are building a PC new or upgrading the one you have, the answers come easily—but only once you know the right questions to ask. How does one determine whether a module is dual- or single-rank? Specs may tell you, but you can’t count on that. If not, physical examination is another way. A look under the edge of a module’s heat spreaders would reveal how many ICs are used. Since the ICs on most performance-oriented memory modules have an 8-bit interface, eight of those make up a 64-bit rank. (Some low-end memory uses four 16-bit ICs per rank. These “chips” tend to be rectangular.)The memory controllers of most consumer processors support up to four ranks of memory per channel, which is why so many dual-channel boards have four slots and why so many quad-channel boards have eight. If every module used in these boards was dual-rank, the memory controller would be “full.”
