Crucial RAM 16GB DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Portable Memory CT16G4SFRA32A

Product Information

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. 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. Man bekommt hier einen guten und günstigen Marken-Arbeitsspeicher. Ich habe mich für die 16GB Version entschieden, die ich in einem SFF-Rechner mit Debian benötige. Mir war weder die Geschwindigkeit, noch die Timings wichtig. Nur günstig und von einem renommierten Hersteller sollte er sein. 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.

Yes, that's some in-the-weeds math. But this explains why in our lead example, DDR4-3600 CAS 20 (11ns) can underperform DDR4-3200 CAS 14 (8.75ns) in certain operations: It takes 2.25ns longer for DDR4-3600 CAS 20 to respond. Most memory buyers won’t get down to that level of granularity, but that explains why you can’t weigh just a single specification in assessing performance memory. Beyond that is overkill for most folks. Programs that run optimally with 64GB or more are generally designed for experienced or professional users who already know how much they need—or at least, who know that they need all they can get.That leads to our general capacity guidelines. We recommend 16GB of main system memory for most users who want to multitask without incurring the above-mentioned slowdown, and 32GB for heavy multi-taskers or those running memory-hogging programs such as video editors. 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. 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. 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) 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.”

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.) One thing to remember is that most systems require a matched pair of modules to run dual-channel mode, or four matching modules to operate in quad-channel mode. While past platforms have occasionally allowed for mixed modes using different modules, those didn’t perform optimally. That doesn’t necessarily mean that you have to ditch an old pair of modules when a pair of empty slots are available, as we’ve had good experience adding a new matched pair to an old matched pair of the same data rate, but doing so may make XMP mode unworkable. We’ve even added 2x 8GB kits next to 2x 4GB kits without breaking dual-channel mode, creating a 24GB (12GB per-channel) configuration as 8GB-4GB-8GB-4GB, by simply leaving the board at default (non-XMP) settings. You’ll just want to make sure the matched pairs are inserted into the proper paired DIMM slots recommended by the motherboard maker. DDR4-3200 could be a better choice for users who can’t afford DDR4-3600 at CAS 18 or lower latency, though. And given the age of these platforms, even slower (and thus, cheaper) memory could be appropriate. Investing in premium RAM for a venerable PC may not make sense within your budget, especially if you think you might upgrade the whole system before long.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.) Der Arbeitsspeicher hat ein wirklich tolles Preis-Leistungsverhältnis. Jedoch ist er im Vergleich zur teureren Konkurrenz doch mit relativ schlechten Timings ausgestattet. Maximal nutzt der Arbeitsspeicher eine Geschwindigkeit von 3200Mhz, kann aber je nach Mainboard/CPU auch mit niedrigeren Geschwindigkeiten genutzt werden. Jedoch, wie oben erwähnt, mit maximalen Timings von CL22. Hier bieten teurere Modelle Timings bis CL14 auch bei 3200Mhz an. Ob einem die Timings wichtig sind, muss jeder für sich wissen. Mir war es egal und daher habe ich ihn auch gekauft. The search ends here for some PC upgraders, as some machines simply can’t be upgraded. The above screenshots, for example, come from an old, DDR3-equipped notebook that doesn’t support modules of 8GB each and already has its two slots filled with 4GB memory modules. A key thing for starters: DDR3 is a sign of an older PC, and you can’t simply swap in DDR4 modules in their place. On both laptops and desktops, DDR3 and DDR4 memory are keyed differently from one another and are incompatible. But if you’re not getting this information from the manufacturer, there are other ways to figure it out.
