CORSAIR VENGEANCE LPX 128GB (4x32GB) DDR4 2666 (PC4-21300) C16 1.2V Desktop Memory - Black

Product Information

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%. Estimated delivery times are provided to us by the respective delivery companies. We pass this information onto you, the customer. We used MSI's MAG Z690 Tomahawk WiFi motherboard in both DDR4 and DDR5 flavors. They're essentially the same motherboard with different RAM slots, making them directly comparable to each other. It helps us eliminate or reduce the performance delta to a minimum instead of using two different motherboards from different brands or product tiers.

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. Also on the list is a 15.6-inch 1,000 nits full HD display that is bright enough to be read in bright sunlight and three (yes three) 1TB SSDs that should be configurable in RAID-5 mode (for extra redundancy). Last but not least, Getac bundles a 3-year accidental warranty, which is what we’d expect on such a costly piece of equipment. There’s also no option for an embedded 4G/5G modem.

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. Corsair's Dominator Platinum has been one of the best gaming DDR4 RAM kits for quite some time now. Its sleek exterior, patented DHX cooling technology, and unrivaled performance has made it a formidable flagship over the years. Corsair's most up-to-date Dominator Platinum RGB DDR4 RAM now comes with RGB lighting using the company's Capellix LEDs, and they're pretty lovely to look at. To throw a brief bit of maths at things, the real-world CAS latency is measured as (CAS Latency x 2,000)/Memory Speed, which in the case of the DDR5-5600 CL28 kit comes in at 10ns. For reference, that's the same as DDR4-3200 with a CAS latency of 16. 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. A 5-megapixel camera is probably overkill but I'll take it; I do also appreciate the built-in Tile feature that help you locate your laptop if you misplaced it as well as the MIL-STD 810H rating.

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?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. If you’re interested in the highest FPS, then you’ll definitely want to add some fast RAM to your system, otherwise you could be leaving a chunk of performance on the table. Why do I see MHz and MT/s when referring to RAM speeds? Dell has been making workstations for more than a quarter of a century, so it knows a thing or two about what makes a good device.
