Tend to be more RAM Modules Greater for Gaming?

It is really common to get this type of issue debated in tech community forums, so nowadays we’re getting a think about the performance impression of having 4 DDR4 memory modules in a very twin-channel method, opposed to just two modules. Within this situation all modules are operating at the exact same frequency, use a similar timings, and provide exactly the same full memory potential.
Twin-channel platforms including AMD’s AM4 or Intel’s LGA1151 need two matched memory modules for dual-channel Procedure, including a second pair will only broaden memory capability and gained’t up grade you to quad-channel memory, for that you choose to’d have to have a Threadripper or Cascade Lake-X processor.
Having said that, we have seen tests close to showing an increase in effectiveness by including two more modules, allegedly devoid of raising memory frequency, or increasing timings.

DIMM Module Rank Configurations

This may give the 4 DIMM module configuration an advantage as it permits many open DRAM web pages in Every single rank. Although the ranks can’t be accessed simultaneously, they are often accessed independently and This implies the controller can mail generate information to 1 rank, even though it waits for read through details Earlier selected from One more rank.
Simply how much of the influence this has on effectiveness depends on the applying along with the memory controller’s ability to make use of open webpages. But what all This suggests is, Indeed it’s doable for 4 modules to boost overall performance above two modules inside a twin-channel procedure.
Demonstrating that we’ll look at a number of benchmarks performed employing a Main i9-9900K and Ryzen nine 3900X processor. Supporting this investigation is Group Group with their T-Force Vulcan Z DDR4-3000 memory. They’ve furnished two 8GB modules in addition to 4 4GB modules, all utilizing the exact same timings.


First up Now we have Connect with of Duty: Modern Warfare where by we see no discernible difference between 2 and 4 RAM modules, for equally AMD and Intel twin-channel platforms. This is probably the kind of overall performance you’d hope to find out for the most part, but it’s not constantly the situation.
It’s an identical story with Shadow in the Tomb Raider. The Intel program noticed up to a 4% performance Raise, undoubtedly not enormous, but it absolutely was a change that we could reproduce again and again. On Ryzen it didn’t issue, two or four modules produced the same end result.
Testing with Assassin’s Creed Odyssey was fascinating, we noticed gains for the two AMD and Intel when applying four memory modules. The Core i9-9900K’s effectiveness was boosted by as much as seven%, and 5% for the Ryzen 9 3900X. Plainly dual-ranked memory is of advantage During this title, at least under these disorders. A powerful 1% minimal efficiency bring about Much Cry New Dawn With all the 9900K. Overall performance was boosted by nine% and although the common frame amount is hardly improved, it’s even now feasible you’d recognize the enhanced one% very low body price. The Ryzen 9 3900X program was persistently a few frames speedier with four RAM modules, although not on the degree where you’d observe a variance.speakers(zvučnici)

Wrap Up

Installing four memory modules inside of a twin-channel procedure can boost functionality in specific situations. Having said that it should be created very clear that this may not immediately translate right into a 5-7% functionality Improve in video games. For that to happen you might want to be a lot more CPU restricted than GPU restricted and that’s seldom the situation when employing fantastic graphics high-quality settings or components configurations.
For instance, we have been tests that has a GeForce RTX 2080 Ti at 1080p. Raising the resolution to 1440p will probable end in neutralizing any gain we just saw While using the two extra modules as online games turn out to be predominantly GPU bound. The same would be true at 1080p employing a lesser graphics card.
It’s also worthy of noting that four modules may also limit memory functionality within the perception that you simply may not be capable to realize the identical frequency and timings that you could possibly with just two modules. To paraphrase, a straight comparison becomes quite tricky to make as There are a variety of variables that must be regarded as.
The Ryzen nine 3900X is limited to DDR4-2933 when employing 4 modules, whereas AMD’s official spec suggests the CPU will tackle DDR4-3200 with just two modules. Dependant upon how very good the silicon is, the integrated memory controller may do a lot better than that. Our chip handles right up to DDR4-3600 CL16 memory with 4 modules, but Regardless of the limit, The purpose is, it will eventually go larger with just two modules.
