If we look at the best, DDR5-6400 C36 was 11% faster than DDR4-4000 C16. So naturally, you can minimize the difference even more if you use DDR4-4000 C14. But, unfortunately, our Ballistix memory kit was not up to the task. As of July 2023, there are no laptops that can house more than 192GB of RAM; at least not “traditional” laptops. Intel's Extreme Memory Profile (XMP) extension evolves alongside DDR4, so now we have the third iteration of XMP. So, what has changed with XMP 3.0? Well, there are now up to five XMP profiles, and users can modify and save two custom XMP profiles directly onto the SPD. ECC Memory - Error-correcting Code Memory, RAM capable of automatically detecting and correcting errors on the fly, generally used in highly sensitive applications, like scientific data collection or banking. Typically only used and supported on servers and workstations, most desktop boards can run it as non-ECC. So, how does it perform? As is always the case with high-performance memory, the benefits are application-specific.When compared to a common DDR4-3200 kit you do get the odd bump, though any benefit is hidden when you move to higher resolutions and graphical details. You will see the benefits if you want to extract every last frame with a high refresh rate monitor.
To ensure a level playing field, both DDR4 and DDR4 memory modules must operate in a similar configuration with identical density and an equal number of memory ranks. Yep, they're exactly the same in terms of actual latency, but since the 3,600MHz kit is faster that's the one we'd recommend. What is the difference between DDR4 and DDR5? Best suited to high-performance Intel builds, the Trident Z Royal makes for the perfect high-speed pairing. This kit will keep your CPU fed with the data it needs at a rapid rate, and it comes out among the top in every benchmark we could throw at it. Like the rest of the RGB lineup, the Dominator Platinum RGB is controlled via Corsair's iCUE software suite. If you have any other Corsair RGB products, you'll be able to import and synchronize your lighting profiles across all devices. We had some issues mirroring our custom keyboard lighting profiles, but the 11 different predefined lighting link settings worked perfectly. That’s because at the time of writing, there are no DDR5 memory modules (so called SODIMM) with 64GB capacities, the current ceiling being 48GB. Mobile supercomputers or portable servers, on the other hand, are essentially desktop replacement/transportable computers with a screen and an input peripheral attached, and can offer up to 2TB of RAM (yes, RAM, not HDD).
Whereas you may want to choose a slower 3,600MHz kit for AMD Ryzen, the Trident Z is a great option for most other high-end PC builds still run on DDR4 memory. Essentially you want to aim for 3,600MHz memory for Zen 2/3 (Ryzen 3000/Ryzen 5000) chips. Though for Ryzen 5000-series chips it has been suggested that 4,000MHz kits are your best bet.
The 7670 sits at the very top of Dell’s product line and competes directly with Lenovo and HP in the brand-new vertical of non-Xeon, 16-inch mobile workstations. It is more expensive than the competition, thanks partly to the adoption of a new technology called CAMM which stands for Compression Attached Memory Module. This is essentially a new proprietary memory technology that reduces the size of memory modules and makes any future upgrade likely to be expensive.Predictably, not every type of workload will benefit from DDR5's higher bandwidth. Take your everyday tasks with Microsoft Office, for instance. The delta between the best (DDR5-6000 C36) and the worst (DDR4-2133 C15) was only 4%. Generally, file compression sees a big benefit. Rendering doesn’t, but then some encoders, like our Handbrake test, show very decent gains. The gaming benefits when using faster RAM, however, are specific to the individual game. Some see benefits while others gain nothing. You still get a 12th generation Core i5 CPU (12600HX with four performance cores and eight efficient cores), a 256GB PCI-E NVMe SSD with OPAL/SED features and TLC (rather than QLC) technology. That means you'll need a newer motherboard and compatible CPU to run faster, newer DDR5 memory. Essentially you have to build a new PC for the new memory specification. Do I need RGB LEDs on my memory DIMMs? He does have some examples of +20%-ish more performance for DDR5 6000 (at 1080p), in a few games, but there are other games with regression too (where DDR4 wins), which this article does not show... and that's important.
The performance benefits vary even in more specialized workloads. For example, we compared the fastest DDR4 and DDR5 memory kits in Adobe Lightroom (DDR4-4000 C16 vs. DDR5-6400 C36) and found that DDR5 is 28% faster, but the gains in Adobe Photoshop (DDR4-3200 C15 vs. DDR5-6400 C36) and Adobe Premiere (DDR4-3600 C16 vs. DDR5-5600 C36) were less than 1% and 3%, respectively. Modern DDR4 16GB memory modules can feature single-rank (1Rx8), or dual-rank (2Rx8) designs with 16-gigabit and 8-gigabit ICs, respectively. DDR5 16GB memory modules, on the contrary, only come in a single-rank layout with 16-gigabit chips. Therefore, we compared the single-rank 32GB (2x16GB) DDR5 memory with an equivalent single-rank 32GB (2x16GB) DDR4 memory kit for an apples-to-apples comparison. This set of Neo RAM from G.Skill runs at 3,600MHz, which puts it in the sweet spot for red team gaming PCs for low latency operation. As a result, this is definitely a more budget-friendly option for mid-range builds with some flair, especially if you can't afford to stretch to the Corsair Dominator kits. Unlike the last transition from DDR3 to DDR4, DDR5 doesn't have more pins than its predecessor. Instead, DDR5 retains the arrangement with 288 pins, but the pinouts are different. As a result, the position of the notch has changed and will help prevent less-experienced users from trying to insert a DDR5 memory module into a DDR4 slot, or vice versa. That's only a small change, though. The real game-changer resides at an architectural level that you don't see on the outside of the DIMM. However, there is a section of laptop users that will benefit from it. Scientists, creative professionals, and students are some users that might require laptops with 128GB of RAM; notebooks that usually go by the name of mobile workstations, as there are hundreds of applications that require such a large amount of memory. Are there laptops with more than 128GB of RAM?DDR4 memory modules sport a single 64-bit channel (72-bit if you take ECC into account). In contrast, DDR5 memory modules come equipped with two independent 32-bit channels (40-bit with ECC). JEDEC also doubled the burst length from eight bytes (BL8) to 16 bytes (BL16). The upgrades, as mentioned earlier, improve efficiency and reduce data access latency. On a dual-DIMM setup, this transformation essentially turns DDR5 into a 4 x 32-bit configuration rather than the conventional 2 x 64-bit configuration on DDR4. InvalidError said:There is no point in using DDR5 for "futureproofing" when you are going to ditch your overpriced DDR5 anyway because today's DDR5 will be considered garbage by contemporary standards in 2-3 years.
When it comes to the actual performance you need, well, that's a whole different story. Bandwidth tests easily show the relative benefits of running faster memory (well, duh) but really that’s not what’s important. What matters is does faster RAM makes a real difference to your PC experience. The true answer is both yes and no, depending on what kinds of tasks you perform and the individual application or game. DDR5 marks a radical change in voltage regulation, too. The motherboard is no longer responsible for voltage regulation because the memory modules have a power management IC (PMIC). (12V on server-grade DIMMs and 5V on mainstream DIMMs.) If you buy 12900k and RTX 3090 and other halo/premium stuff then you don't care about price at all, so of course you buy DDR5, preferably 6000 or higher, because 4800 is really bad, actually. But those people are in the minority 5%, everyone else can skip it with ease and peace of mind, because it's not worth it. At DDR4-4000 with 15-16-16 timings, the Trident Z Royal kit is probably the perfect combination of high frequency, low timings, and broad platform compatibility. It does require 1.5V to operate at that spec—which is at the high end for a default voltage—but fear not, it will be able to run year after year.DIMMs - Dual In-Line Memory Module, the physical circuit board that holds the RAM chips that plugs into the slots on your motherboard. No, it won't. Even though both types have 288 pins, DDR4 and DDR5 memory is electrically incompatible. The two types have a different notch position, to prevent anyone from inserting a DDR5 module into a DDR4 motherboard, or vice versa.
