It may be due to chip density, especially if you have an older DDR3 based system. Your system may require 2Gbit (Gigabit) density DRAM chips and the memory you installed is using 4Gbit density chips which is not compatible. Not to be confused with the term Gigabyte (capacity of the memory). 2Gbit chips are no longer being produced by the DRAM chip manufacturers therefore we're unable to manufacturer compatible modules.

- Shut down and unplug your computer.
- Reinsert the memory module(s) with the largest capacity in the first socket followed by the smaller capacities in descending order. To ensure the memory modules are installed properly, line up the memory notches with the key in the memory socket, then push the memory firmly into the socket until the tabs lock the memory into place.
- Make sure all the cables in your computer are connected properly. You may have failed to connect a needed power connector to the motherboard or accidentally disconnected a cable to your hard drive.
- If you are receiving a blank screen after the installation of DDR5 memory, please allow the system to remain powered on with the blank screen displayed for at least 10 minutes. After such time if nothing happens, power cycle the system and confirm if it boots successfully. If you receive the blank screen again, let it sit idle another 5 minutes. This is done to allow some systems the time it needs to optimize the new RAM.
- If you have properly installed the recommended memory and the PC still does not boot or recognize the memory, you may need to download the latest BIOS from your computer manufacturer’s Website.

Additional memory will not necessarily increase the performance of your computer. It will allow you to run more programs or processes at once or more memory intensive programs. There may be a performance increase if the original amount of memory installed was close to insufficient for the programs and processes you use the computer for.

Parts sold in kits (denoted by "K2," "K4" or “K8” in the part number e.g., KF572RH38RBK8-256) are packaged for use in dual, quad, or octal channel configurations. The desktops workstations, and laptops that support these configurations are designed to access multiple identical memory modules, aggregating their bandwidth for more performance. Kingston ensures that only modules with matching components are packaged into dual (K2), quad (K4), and octal (K8) channel kits. Single modules purchased at different times may feature different components. While it’s unlikely to cause any performance or compatibility issues, it’s recommended to always buy kits for multi-channel systems to all components are the same.

Electrostatic Discharge (ESD) is the discharge of built-up static electricity. ESD should not be taken lightly as this is one of the few things an individual can do to damage or destroy their electronic components.
Static electricity occurs naturally because of friction, such as when walking barefoot on carpet on a dry, windy day. When static build up occurs on a body it will discharge when in contact with a conductive surface, like metal. This includes conductive electrical components like memory modules. A discharge of ESD onto a memory module may go unnoticed when installing into a PC, but the charge introduced may cause serious damage to the circuits. The damage may be immediate, or manifest overtime.
How to prevent ESD
The best method of preventing ESD is to ground yourself before handling electronics. You can also use ESD protective equipment, such as an ESD wrist strap or a grounding mat to reduce the chances of ESD. The following steps below will also help reduce the chance of ESD:
Standing – It’s recommended to stand when working with components inside a computer. When sitting in a chair, it’s common for people to lift their feet off the floor, which removes the path to grounding for ESD.
Cords - Ensure all cords are removed from the back of the computer (power cord, mouse, keyboard, etc.).
Clothing – Do not wear fabrics that are more likely to build up ESD, such as a wool sweater.
Accessories - To help reduce ESD and help prevent other problems, it is also good practice to remove all jewelry.
Weather - Electrical storms can increase the ESD risk; unless necessary, try not to work on a computer during an electrical storm. Very dry areas and wind also contribute to electrostatic build-up

If you have properly installed the memory and the Notebook still does not boot or recognize the memory, you may need to download the latest BIOS from your computer manufacturer’s Website.
Note: Kingston is in no way responsible for any problems resulting from flashing the BIOS. Flashing the BIOS is merely a troubleshooting suggestion. Customers who flash the BIOS do so at their own risk. All instructions on how to upgrade the BIOS will be provided by the computer manufacturer or the 3rd party BIOS manufacturer and not by Kingston.
Not all Notebook systems will support overclocked memory. There may be limitations with the processor model and type that prevent these from working at higher speeds/lower latencies.
However, overclockable memory can also operate at industry standard speeds and timings. To enable standard speeds, you may need to go into the BIOS and set the memory to the default settings. Contact Technical Support if you are unsure of how to do this, as some Notebook manufactures may limit access to these settings.

In many cases, the BIOS or a diagnostic program will report the memory bus frequency, which is half of the frequency for DDR type memory. As its name implies, DDR (Double Data Rate) data rate is twice the memory bus frequency. So if the memory bus speed is 800MT/s and you are using DDR3-1600 memory, the RAM is running at the correct speed.

To increase the density, DRAM semiconductor manufacturers must continually improve their design and shrink the silicon wafer process (measured in nanometers or nm) to increase the number of memory cells, generally within the same package (chip) footprint as the previous generation. By doing this, the same JEDEC PCB (Printed Circuit Board) designs for memory modules can be utilized.

32Gbit DRAM refers to memory chips with a density of 32 gigabits (Gb). These are planar (non-stacked) chips, that enable high-capacity modules without the use of 3D stacking technologies like Through-Silicon Via (TSV) or Dual-Die Package (DDP). Instead, DRAM semiconductor manufacturers use advanced lithography techniques to fit more memory cells into the same physical chip area. Compared to earlier 16Gbit or 24Gbit DDR5 chips, 32Gbit DRAM significantly increases the capacity of memory modules. This allows systems to support higher memory capacities using the same form factor, helping reduce reliance on more complex and expensive stacked DRAM solutions. 32Gbit-based memory modules are compatible with most Intel and AMD systems, but a BIOS upgrade may be required. Check with the Kingston Configurator to see which systems are confirmed compatible.

AEMP is an acronym that stands for ASUS Enhanced Memory Profile. This is an ASUS BIOS tool (only available on select ASUS motherboards) that analyzes JEDEC industry standard memory modules based on their DRAM components and creates an overclock profile in the BIOS with increased speed, lower timings, and higher voltage. While overclocking memory can be beneficial for many applications, keep in mind that doing so using a module that isn’t engineered for overclocking may be risky. The DRAM components used on standard memory modules may not be stable beyond JEDEC standard speeds. If voiding your memory warranty is a concern, we recommend using an overclockable solution, such as Kingston FURY™, designed and tested for extreme performance with a lifetime warranty.

When booting a DDR5 system for the first time, when the memory configuration has changed, or when the BIOS/firmware has been updated, a process called memory training is initiated during POST (Power-On Self-Test). Some DDR5 PCs may take 3-5 minutes to complete training, while some DDR5 server/workstation systems may take up 15 minutes to complete. This is often mistaken for a system freeze or problem, especially if the screen remains blank. If there is a memory error or other issue, these are typically indicated by LED lights or codes on the motherboard, or an error reported on the screen. If there is no such error, it’s important to let the system complete memory training.
Memory training is a critically important step for DDR5, which requires optimization between the memory controller, BIOS, and DRAM components. Failure to do so can cause instability or performance issues. Once training is complete, all subsequent boots are significantly shorter. We do not recommend changing settings to bypass training in any way. Training time can vary depending on the amount of RAM installed. More installed RAM capacity usually means a longer memory training period.
When memory training is complete, the system will either reboot or proceed to the operating system.
