Help Me Choose: Memory


Random access memory (RAM) - Commonly known as system memory is the workhorse behind the performance of your system. RAM serves as the temporary storehouse for the flow of data. It remembers what programs, applications and documents you use most frequently so it can access these as quickly as possible.

Without sufficient RAM, a computer’s operation can slow down considerably as the computer starts using hard drive space to handle the data flow.

Adding memory at the time of purchase can be more cost-effective and convenient than upgrading later.

Memory speeds

  • Offering DDR4 2666 MHz and DDR4 2400MHz
  • Maximum memory speed depends on the processor. For example:
    • 2666 MHz memory automatically clocks down to 2400 MHz when paired with Celeron, Pentium or i3 Processor on Dell OptiPlex systems.
    • 2400 MHz memory automatically clocks down to 2133 MHz when paired with 6th generation Processor on Dell OptiPlex systems.
  • With 32-bit operating systems, such as the 32-bit version of Microsoft® Windows® 10, the system may utilize up to 3.5GB of memory for system performance (out of 4GB), while the remaining 0.5GB is allocated to address space for various hardware components.
  • 64-bit operating systems can utilize more than 4GB of system memory and can require applications designed for 64-bit. Majority of business applications today are designed for 32-bit. However, the trend will continue toward 64-bit operating systems, as system memory plays a greater role in application performance.

Memory modules should be installed in pairs of matched sizes, speed and technology. Pairs of matched memory size are also referred to as dual-channel configurations, which yield the highest performance. If the memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.

For configurations supporting Intel® Optane™ memory.

Intel® Optane™ memory is a system acceleration solution that is paired with slower storage devices such as SATA HDD/SSDs to accelerate performance to near PCIe/NVMe Solid State Drive levels. The most-used files will be stored in Intel® Optane™ memory for faster access using the smart adaptive SW to improve overall system performance. The hard drive and Intel® Optane™ memory will be seen as one drive volume, allowing it to be used just a like a standard drive. Adding 16GB of Intel® Optane™ memory to a system with a 1TB HDD and 4GB DDR delivers better responsiveness than a system with a 1TB HDD and 8GB DDR w/o Intel® Optane™ memory.

Requirements for Optane:7th or 8th Gen Intel® Core™ processor platforms with 7th or 8th Gen Intel Core™ Processors and Intel® Rapid Storage Technology (Intel® RST) driver (factory installed by default when Intel® Optane™ is purchased).

Frequently Asked Questions:

What is Intel® Optane™ memory, and why is it called memory?

Intel® Optane™ memory is a system acceleration solution for the 7th Gen and 8th Gen Intel® Core™ processor platforms. This solution comes in a module format and by placing this new memory media between the processor and a slower SATA-based storage devices ( HDD, SSH or SATA SSD), you are able to store commonly used data and programs closer to the processor, allowing the systems to access this information more quickly and improves overall systems performance.

Does Intel® Optane™ memory replace DRAM?

The Intel® Optane™ memory module does not replace DRAM. It can be, however, added to DRAM to increase systems performance.

Will Intel® Optane™ memory also accelerate an SSD? If so how much?

Yes! Intel® Optane™ memory can be sued to accelerate and type of STA-based storage media, including SATA SSDs. However, the performance benefit of adding Intel® Optane™ memory will be greater on slower storage devises like an HDD.

Why should I choose Intel® Optane™ memory instead of simply using an SSD?

You have choices based upon your requirements. Typically, if you need high capacity storage, you will choose an HDD. SSDs are often lower in capacity and tend to be more expensive. Paired with a HDD, Intel® Optane™ memory delivers increased responsiveness of an SSD with the high capacity of a HDD

Why would I need 32GB capacity instead of 16GB? What is the difference in performance?

The main difference between 32GB and 16 GB is the number of applications that can be accelerated. The 32GB module is ideal for power users who often use a variety of intensive applications, such as prosumers and gamers. It is also recommended if you play more than one game at a time.

How many times do I need to launch and app or a file to get the full acceleration from Intel® Optane™ memory?

The second time an application or file is used, it is accelerated and you will experience a huge benefit. One the third launch is when the fill effect of Intel® Optane™ memory kicks in. Note: Intel® Optane™ memory prioritizes frequently used applications and files thus, infrequently used files and applications will fall out of cache.

How many games can I accelerate with Intel® Optane™ memory?

This is highly dependent on the size and architecture of the software you are using, as well as other software being used and the configuration of your platform.

If I use Intel® Optane™ memory with an HDD to accelerate my games, game launches and level loads become faster and close to that of an SSD experience, but what about the game play? Is the game play impacted?

Game play will not be that different between an SSD and an HDD based systems since the games are loaded into DRAM during play.
