Why can't I get my HyperX module to run at the advertised speed?
HyperX memory is built with more aggressive timings than industry standard (JEDEC) memory. HyperX modules are specifically engineered to meet the rigorous requirements of PC enthusiasts. HyperX offers faster speeds, lower latencies, and higher data bandwidths. Using HyperX memory may require that you go into the BIOS and set the overclock profile manually in order for the BIOS to recognize the memory properly. HyperX memory is tested at the advertised speed at the factory, and is also tested and qualified on a broad range of motherboards by the world’s leading motherboard manufacturers. However, because of the unlimited options available to users for their custom builds, we cannot guarantee HyperX to be compatible with every possible configuration. Motherboard design variation and other system components, such as power supply, processor model, graphics card, and system cooling, may affect the ability of the memory to overclock to the advertised speed.

Before setting the timings it's a good idea to have the latest BIOS. The BIOS can be downloaded from your motherboard manufacturer's website. It's also a good idea to set the BIOS to the default values to rule out any other possible conflicts. Please check your processor’s documentation to make sure it supports the speed of the memory you're installing. Also check the specific motherboard’s Qualified Vendor List, and any special instructions they have for using overclocked memory.

If you are unable to successfully overclock the memory, please contact our Technical Support department for assistance. We can help you find a memory module that is compatible with your system. FAQ: KTM-021011-HYX-01
I've installed HyperX in my system and I am manually setting the timings in the BIOS. I see entries like "CAS Latency" and "RAS to CAS Delay", but I don't see "Command Rate". Where can I set this timing?

Many motherboards automatically set the "Command Rate" and do not allow it to be manually set by the user.

FAQ: KTM-021011-HYX-05
I have set the timings that you list, but there are many other timings shown in the BIOS. What should I set these to?

If there are timings in the BIOS we do not list in the latency timings for your HyperX memory, please leave these timings at their default setting.

FAQ: KTM-021011-HYX-06
What do the memory timings listed for the HyperX memory (i.e. 10-11-12) mean?
Timing Timing Definition Abbreviations What it does
10 CAS Latency CL Delay between activation of row and reading of row.
11 RAS to CAS (or Row to Column Delay) tRCD Activates row.
12 Row Precharge Delay (or RAS Precharge Delay) tRP or tRCP Deactivates row.

CAS latency:
CAS Latency is the ratio of the memory's column access time divided by the current system clock. The column access time turns out to be a constant value, so you can see as you in increase the system clock it becomes harder to achieve a lower CAS latency (e.g., the denominator grows, but the numerator stays the same).

RAS-to-CAS:
This is the latency between the Row Address Strobe and Column Address Strobe. Basically the delay between accessing the Row and the Column memory addresses.

Row Precharge Delay:
The number of clock cycles taken between the issuing of the precharge command and the active command.

FAQ: KTM-021011-HYX-09
I installed HyperX memory and my system fails to boot or it locks up intermittently.
HyperX memory is built with aggressive settings. Not all systems will be able to run at these aggressive settings.

Please verify that your HyperX module is compatible with the specific Intel or AMD chipset on your motherboard. If your memory uses XMP profiles for overclocking, change the memory settings in your BIOS to “auto” and/or clear the CMOS to return it to default settings. If the memory fails at the default settings, please contact our technical support for assistance.

Note: HyperX Predator modules feature two overclock profiles (XMP). Profile 1 is the most aggressive, and the advertised speed of the part. Profile 2 is less aggressive, in case the first profile is too extreme for your system. FAQ: KTM-030615-HYX-10
I've installed the HyperX memory and it does not run at the rated speed. Why?
HyperX Predator and Savage memory use XMP profiles to overclock, however these modules ship from the factory at JEDEC standard values. Some systems do not support overclock speeds and latencies upon first installation, so in order to give every customer the best experience, Kingston sets the module to the JEDEC standard values, giving the user the choice to overclock using the XMP profiles if the system supports it. The XMP profile can then be enabled within the system BIOS.

Plug-N-Play (PnP) modules, such as FURY and Impact, ship from the factory at the advertised overclock speed and latency. If the system is not able to run at the overclocked settings, the system may either use the next highest timing profile or default to the JEDEC standard timings. FURY and Impact also featured an XMP profile that matches the advertised speed and latency. This can be used to force the system to overclock the memory if it does not overclock automatically. A second, less aggressive profile is sometimes available, in case the first profile is too extreme for your system. FAQ: KTM-030615-HYX-03
How do I change the color and patterns of the Predator DDR4 RGB DIMMs?
HyperX Predator DDR4 RGB DIMMs come from the factory featuring a rainbow wave pattern, which will work on any DDR4 motherboard. To change the color or pattern, an RGB compatible motherboard with customization supported through the BIOS or an RGB application is required. HyperX has worked with ASUS, ASRock, Gigabyte, and MSI to enable color and pattern changes through their respective RGB applications. Please check your motherboard’s compatibility with Predator DDR4 RGB, as not all models or chipsets support the ability to customize the RGB effects (effects may be limited). On compatible models, the latest BIOS and version of the RGB application are also required to customize Predator DDR4 RGB. Please contact the motherboard manufacturer for questions or issues regarding their RGB software application. FAQ: KTM-060818-HYX-11
Why do the FURY Plug N Play DIMMs not work out of the box at the advertised speed in my AMD Ryzen system?
AMD Ryzen processors override the Plug N Play feature of HyperX FURY memory, forcing them to run at slower speeds or timings out of the box. To enable the advertised speed, Profile 1 must be selected within the BIOS. This will force the Plug N Play speed and timings. Note that not all AMD Ryzen processors will support all FURY speeds. Check with your motherboard manufacture for a list of tested overclock speeds or refer to our AMD Ryzen compatibility sheet.

What systems/motherboards support the Predator DDR4 at 4000MHz and above speeds?
Only select motherboards can achieve speeds of DDR4 at 4000MHz and above, typically limited to Dual or Quad channel configurations with only one memory bank group populated (one K2 or K4 kit). We recommend checking the memory Qualified Vendor List (QVL) of the gaming motherboard manufacturer to verify the extreme Predator DDR4 kit is supported, and in which configuration/sockets. You can also check the Intel XMP certified memory list here for verified systems with the Predator DDR4 kits.

Since the memory controller resides within the Intel processor, it’s critically important to use premium cooling for the CPU and the system case for improved stability. We recommend Intel X or K series processors as well. You can find a list of these models here. FAQ: KTM-060818-HYX-13

When I installed memory in my Notebook, the system did not boot or did not recognize the memory. How do I resolve this?
If your Notebook did not boot, there may be an issue with the installation. Try re-seating the memory to be sure the memory is making proper electrical contact. To do this, first shut down the Notebook, then remove the battery pack and unplug the power cord. Reseat the memory firmly into the socket and then push down on the memory to lock it in place. Replace the battery pack and power cord and boot the system.

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. FAQ: KTM-012711-GEN-12
When I installed memory into my desktop computer, the system did not boot or did not recognize the memory. How do I resolve this?
If your desktop did not boot, there may be an issue with the installation. Try re-seating the memory to be sure the memory is making proper electrical contact. Shut down and unplug your computer.

Reinsert the memory module(s) in the sockets and sequence designated by the manufacturer of the system or motherboard. 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 have properly installed the 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.

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 systems will support overclocked memory, especially at higher speeds. There may be limitations with the processor model, insufficient power, and/or cooling that have affected the memory overclock.

HyperX Predator and Savage memory use XMP profiles to overclock, however these modules ship from the factory at JEDEC standard values. Some systems do not support overclock speeds and latencies upon first installation so in order to give every customer the best experience, Kingston sets the module to the JEDEC standard values, allowing the user the choice to overclock using the XMP profiles if the system supports it. The XMP profile can then be enabled within the system BIOS.

Plug N Play (PnP) modules, such as FURY and Impact, ship from the factory preset to the advertised overclock speed and latency.

Will additional memory speed up my computer?

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 insufficient for the programs and processes you use the computer for.

FAQ: KTM-012711-GEN-07
How do I install memory into my computer?

For desktop computers, shut down and unplug your computer and open the case. Please refer to your motherboard manual for proper order sequence for installing the memory. Installing memory in the incorrect order could result in lost potential memory performance, or in some cases failure to boot.

Remove the memory module as shown in Fig 1. Push the tabs (1) outward and the module will gently pop out of it's socket (2). Remove it completely from the socket.

To Install the new memory module see in Fig 2. 

Push the tabs (1)that are at the ends of the memory socket outward and align the memory notches with the key of the memory socket (2), then push the memory down FIRMLY into the socket so the latches lock the memory in place (3).

If the memory has been installed but is not detected by the computer, repeat the process of removing and then reinstalling the memory to be sure the module is firmly seated. If the memory is still not detected, please contact Technical Support to be sure you have the correct memory part for your system.

For notebook computers, please note that before you remove/install memory in notebooks you need to shut down the unit and remove the battery pack and power cord. Push the memory in FIRMLY so that it makes good contact (it is important to push the memory in FIRMLY) into the socket before pushing it down to lock in place (See figures below) . Once the memory is installed please put the battery back in your unit and give it power using the power cord and not solely from the battery. If the memory has been properly installed and still not detected and you do have the correct memory you should make sure you have the most up to date BIOS* from your computer manufacturer's website.

*BIOS - Basic Input/Output System is installed on the computer's motherboard. It controls the most basic operations and is responsible for starting your computer up and initializing the hardware. It is data that is usually held in a ROM chip, which can be updated by "flashing" the BIOS as it's called. BIOS upgrades may correct errors, support new CPUs, support new hardware, including memory etc. BIOS updates are usually obtained by the computer's manufacturer's website.

NOTE: Kingston in no way is responsible for any problems resulting from flashing the BIOS. Flashing of the BIOS is merely a trouble shooting suggestion. Customers that flash their 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.

XX FAQ: KTM-012711-GEN-18
What is the difference between the part numbers that are in kits and the parts that sold individually?
Parts sold in kits (denoted by "K2" or “K4” in the part number are specifically packaged for use in Dual (K2) or Quad (K4) Channel motherboards. Although Dual and Quad Channel technology resides on the motherboard itself (inside the chipset), the memory modules need to be installed in pairs or identical groups Dual or Quad Channel mode to function properly. Identical modules packaged in a kit work best because the motherboard will be accessing all the memory modules as a single memory location with a wider bandwidth.

FAQ: KTM-020911-GEN-19
My BIOS or a diagnostic program such as CPU-Z shows the memory is running at half the frequency. Why?

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 800MHz and you are using DDR3-1600 memory, the RAM is running at the correct speed.

FAQ: KTM-071015-GEN-20
What is ESD?
  • ElectroStatic Discharge, ESD is simply the discharge of built up static electricity, like when you rub your feet on carpet and then you touch something etal. ESD should not be taken lightly as this is one of the few things an individual can do to damage or destroy their computer or hardware components. ESD can occur without feeling a shock and can occur when only working on the inside of the computer or handling hardware.
  • How to help prevent ESD
  • The best method of preventing ESD is to use an ESD wrist strap or a grounding mat or table.However, because most users do not have access to these items, we have included the below steps to help reduce the chance of ESD as much as possible.          
  • Standing – We recommend that you are standing at all times when working on the computer. Setting on a chair can generate more electrostatic.
  • Cords - Make sure everything is removed from the back of the computer (power cord, mouse, keyboard, etc).
  • Clothes - Make sure not to wear any clothing that conducts a lot of Electrical Charge, such as a wool sweater.
  • Accessories - To help reduce ESD and help prevent other problem, it is also a good idea to remove all jewelry.
  • Weather - Electrical storms can increase the ESD risk; unless absolutely necessary, try not to work on a computer during an electrical storm.In very dry areas, the air itself becomes a part of the electrostatic build-up mechanism every time there is an air flow (wind, air conditioning, blower) passing over an insulated surface.Do not let high humidity levels build a false confidence, and beware of corrosion problems with interconnects and other electrical interfaces.
