Dual Channel Vs Quad Channel Ddr3


Upgrading your random access memory, or RAM, is one of the easiest ways to improve your computer speed instantly. Whether adding additional RAM or changing your channel configuration, you’ll experience a heave in speed and processing power when upgrading your RAM.

We mentioned the existence of quad-channel RAM in our previous commodity near single and dual-aqueduct RAM. Nonetheless, we didn’t get a chance to hash out quad-channel RAM and its merits and downfalls. And then, let’s deep dive into quad-aqueduct RAM and compare it to standard dual-channel RAM.

Dual-Channel vs. Quad-Channel RAM: What’s the Difference?

Dual-aqueduct and quad-aqueduct RAM are substantially and direct comparable to each other. Therefore, virtually quad-channel enabled RAM tin can run in a dual-channel setup. However, the dual-aqueduct slots will bottleneck the quad-channel RAM.

The price point volition exist the nearly significant difference between quad-aqueduct and dual-channel RAM. Thus, the applications of the units will be different. The other principal departure is the speed of the units. Quad-channel RAM is faster than dual-aqueduct RAM as its connection to the board uses each of the 4 lanes on your motherboard to the fullest capacity, improving speed for users with additional power to spare.

This additional ability does come at a cost, though. Upgrading to a quad-channel setup typically requires a pretty hefty cost increase. In addition, perchance shockingly, the operation of quad-channel RAM isn’t typically that much better than dual-channel RAM, bold all other factors between the ii units are the aforementioned.

Is Quad-Channel RAM Better than Dual-Channel RAM?

While it may audio like a unproblematic doubling of speed to the uninitiated, quad-channel RAM is non necessarily that much faster than your current dual-aqueduct setup. This is because when upgrading to quad-aqueduct RAM, you’re increasing the memory bandwidth, non the clock rate. This ways you’re boosting the speed with which your RAM tin transfer information between itself and the motherboard, not its bodily speed.

Succinctly, your retentivity’s clock rate tells you how many processing cycles your retentivity tin can perform in a second. Conversely, the memory bandwidth is how much information tin be sent from the CPU to the memory.

Bandwidth is generally considered a more accurate metric when measuring your RAM’s speed. However, fifty-fifty a higher metric won’t necessarily mean better overall functioning.

But, allow’s look at what PC World discovered when they tested dual and quad-channel RAM in a head-to-head comparison.

PC World’south Tests: Is Quad-Channel RAM Significantly Faster?

We’ll start by defining the methods and variables PC World used to exam the two RAM units. Both units were tested in the exact aforementioned build. The simply divergence between the builds was the RAM sticks.

Since the testing required a full-sized X99 motherboard, a PC outfitted with an ASUS X99 Pro was used. The PC likewise included a GTX 970, a hexacore i7-5820K, and 16GB of DDR4 RAM. In quad-aqueduct mode, iv sticks of four gigabytes each were used. In dual-aqueduct style, two eight-gigabyte sticks were used.

The first test they ran was to benchmark the memory bandwidth. As expected, the quad-channel RAM performed significantly improve than the dual-aqueduct RAM, with 47 GB/s to the dual-channel RAM’s 27 GB/south. However, this category was the only category with a significant divergence in metrics.

The next test PC World performed was to test how fast the system could encode a video. They used Handbrake to encode the video twice to the same profile, and the quad-channel RAM did perform amend, though not also much. It took effectually 26.1 minutes for the quad-aqueduct build to encode the video and approximately 26.four minutes for the dual-aqueduct build.

They also tested the 2 builds confronting PC Mark viii’s Creative Conventional test, which aims to simulate high-intensity processes like photo and video editing. Instead of the GPU examination, they used the conventional CPU test, which was a test of the RAM, not the VRAM.

In this category, the dual-channel setup actually performs very slightly improve than the quad-channel setup. The dual-channel structure scored 5,397 points on the Creative Conventional test, while the quad-channel design scored 5,389 points. Not a huge departure, but disappointing nonetheless.

In that location was as well a slight merely ultimately inconsequential departure when using PC Mark’s Home and Work tests. However, the tests were so similar that they didn’t carp publishing the charts for both tests. The quad-aqueduct RAM scored 4461 on the PC Mark viii Habitation examination, while the dual-channel configuration scored 4664.

Next, PC Earth tested the RAM’s performance when compressing and decompressing files. Both WinRAR and 7Zip were used in the test, and at that place was a balmy improvement in both when using quad-channel RAM compared to dual-channel. The quad-aqueduct configuration was only a bit faster when using WinRAR, scoring 17,183 on WinRAR’south pinch test to the dual-channel RAM’s 16,803. With 7Zip, there was a more noticeable boost with a score of 3,483 to the dual-channel RAM’s 3,251. All the same, neither of these scores is so much higher that they would brand much of a difference to someone’s daily life.

Lastly, PC World benchmarked the two systems using gaming metrics. They selected older games more aligned with the GTX 970’due south benchmarks. Notwithstanding, the quad-channel system did not perform noticeably better than the dual-channel organisation on any game in terms of the frames per second.

After all of these performance tests, information technology’south prophylactic to say that you won’t experience a significant performance bump when going from dual-channel to quad-channel RAM unless you’re besides increasing your RAM allotment.

Co-ordinate to PC World’due south tests, dual-channel RAM and quad-channel RAM performed very similarly, all other factors abiding.

When Should I Choose Quad-Aqueduct RAM?

The all-time way to put information technology is that if you have the option to install quad-channel RAM already, you might also. But, suppose y’all’re looking to buy or build a new organisation, particularly a very compact one. In that case, you lot won’t feel a meaning functioning decrease if you opt for a board that only runs in dual-channel.

At present, if y’all are going from single-aqueduct to dual-channel, y’all’ll definitely want to get the dual-channel setup. Dissimilar dual-channel to quad-aqueduct, single-channel to dual-channel will give you a performance boost of about 15%, assuming both sets of sticks are otherwise identical. So, upgrading from single to dual-aqueduct RAM is highly recommended to meliorate your computer’s operation.

Additionally, using quad-channel RAM puts more pressure level on the reckoner’s retention controller—the component in the motherboard that allows the computer to read and write to the RAM. Every bit a issue, it may crusade additional wear-and-tear and cause the system to require replacement parts earlier in its lifespan, mainly if the computer is used often.

Tin can I Mix Dual-Channel and Quad-Channel RAM?

Technically, yeah, you tin can mix dual and quad-channel RAM sticks. However, doing this will crusade the motherboard to run exclusively in dual-channel mode, as a number of the sticks will be unable to support quad-channel manner. So, you won’t get the aforementioned efficiency as buying a RAM kit.

Additionally, y’all may notice that mixing RAM sticks causes internal errors that can only exist stock-still past removing the offending RAM sticks. It’due south possible that—for no other pertinent reason—your estimator will be unable to boot if the RAM sticks don’t match.

Thus, we recommend buying a RAM kit if you desire to upgrade to quad-channel RAM.

Quad-Channel vs. Dual-Channel RAM: 5 Must-Know Facts

  • Quad-channel RAM has twice the memory bandwidth of dual-channel RAM.
  • Quad-channel RAM puts more pressure on the motherboard’s memory controller.
  • Dual-channel RAM performed almost the aforementioned as quad-channel RAM when stress tested in otherwise identical PCs.
  • Quad-aqueduct RAM is significantly more than expensive than dual-channel RAM.
  • Quad-channel RAM must exist purchased in kits of iv sticks to ensure compatibility between the RAM sticks.

Concluding Thoughts

Upgrading your RAM is just one manner you lot can customize your PC to accommodate your exact needs. While at that place may non be a huge performance boost from upgrading your RAM to quad-aqueduct, there are tons of other components y’all can upgrade that will requite you the functioning heave you’re looking for!
