This memory is built with more aggressive timings than our other product lines of memory.HyperX modules were specifically engineered and designed to meet the rigorous requirements of PC enthusiasts. HyperXoffers faster speeds, lower latencies, higher data bandwidths and lower power consumption. Using HyperX memory may require that you go into the bios and set the optimal timings manually in order for the BIOS to recognize the memory properly. Because this memory is not tested for compatibility with any particular system we cannot guarantee that it will be possible to overclock the memory, the success of which depends on the overall system configuration.
Before setting the timings it's a good idea to have the latest bios if the modules do not work after setting these timings as the BIOS could be limiting the proper detection of the memory. The BIOS can be downloaded from your motherboard manufacturer's website. It's also a good idea to set the bios to their default values to rule out any other possible conflicts.Please check your processors documentation to make sure it supports the speed of the memory you're installing.
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. You may also visit our memory configurator at:
You will need to manually set the speed, timings and voltage appropriately or use one of the XMP profiles if your motherboard supports it. Some systems are not able to properly operate at the lower latency settings offered by HyperX modules. Some diagnostic programs will only read the default settings on the Serial Presence Detect (SPD) on the module. So it would not take into account the settings you manually changed or the XMP profile you chose.
Please refer to the spec sheet for your specific HyperX memory product for the appropriate setting.
Many motherboards automatically set the "Command Rate" and do not allow it to be manually set by the user.
If there are timings in the BIOS we do not list in the latency timings for your HyperX memory, please leave these timings at its default setting.
|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 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).
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. In this times the sense amps charge and the bank is activated.
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. These will be listed on the product pages on the HyperX website. If your memory uses XMP profiles for overclcoking, change the memory settings in your BIOS to auto.
If the memory fails at the default settings, please contact our technical support for assistance.
With HyperX memory that uses XMP profiles, the default settings used are JEDEC standard values. Some systems do not operate at speeds greater than JEDEC settings and 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 support it.
With PnP modules, 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.
In Windows, click on the start button and open "Control Panel".Use classic view for Vista and 7. Then open "System". This will display basic information about the computer including the amount of RAM installed.
In MacOS, select "About This Mac" or "About This Computer" from the Apple menu in the upper left corner of your Desktop. This will provide information about your Mac's total memory (built-in memory plus DIMMs or SIMMs installed).
In Linux, open a terminal window and enter the following command: cat /proc/meminfo
This will show the total amount of RAM as well as other memory information.
First, make sure you have the correct memory for your Notebook. Please refer to Kingston’s on-line Memory Search at www.kingston.com for assistance. After you confirm that you have the correct memory for your system, do the following:
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.
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.
For desktop computers, shut down and unplug your computer and open the case. Please note: The higher capacity memory should be installed in slot 1 followed by the next lower capacity memory in slot 2 and so on. Please refer to your motherboard manual for proper slot identification.
Remove the memory module as shown in Fig 1. Push the tabs (1) outward and the module will gently pop out of it's slot (2). Remove it completely from the slot.
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 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.
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 there 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.
Parts sold in kits (denoted by "K2" or "K3"in the part number, e.g. – KVR400X64C3AK2/2G) are specifically packaged for use in Dual or Triple Channel motherboards. Although Dual and Triple Channel technology resides on the motherboard itself (inside the chipset), the memory modules need to be installed in pairs or sets of three for Dual or Triple 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. Kingston suggests the use ofmodules sold in kits for Dual or Triple Channel enabled motherboards.
Yes. In most cases if the computer supports a slower speed, it will clock down to a slower speed as long as it is the correct memory type (DDR, DDR2, etc). But be aware the function of clocking down depends on the computer and it isn't guaranteed to work in every case
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.
ElectroStatic Discharge, ESD is simply 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 computer or hardware components.It is like when you rub your feet on the carpet and you touch something metal.ESD can occur without the user feeling a shock and will 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.
