Knowing your RAM’s serial number is important for verifying authenticity and warranty claims.
The serial number is stored in the RAM module’s SPD (Serial Presence Detect) chip. It can be accessed usingsystem commandsorhardware monitor apps.
The data includes memory specifications likemaximum speed, voltage,memory rank, chip manufacturer, serial number, etc.
However, some RAM may not display the serial number or show NULL. In that case, you’ll need tophysically check the labelon the module.
This article will guide you on how to check your RAM’s serial number effectively.
Using Command Prompt
you may simply type a singlecommand in Command Promptand the system displays all RAM details.
But I suggest you get the manufacturer, and slot detail along with the serial number of your RAM. This could be useful if you havemultiple memory sticksand want to know the serial number of the RAM.
In Powershell
Alternatively, you may also use PowerShell to check RAM serial numbers. Although the command is different, bothPowerShell and Command Promptdisplay the same information.
Using system commandsis the easiest but definitely not very effective. Users might get confused when multiple memory modules are connected.
It may not display the slot used correctly. So, if I have four memory modules connected, getting data on each of them will get confusing.
Furthermore, the serial number column might also display000000. To get around this, I suggest using a third-party hardware monitor application.
From Hardware Monitor Application
you may find an application that displays all theinformation about the system. Thisincludes the motherboard,graphics cards, and everything in between.
As for memory, it displays DDR type,number of channels used, size, and all the information coded into the SPD chip.
you may also find several other applications that read memory information like HWMonitor or HWiNFO. But personally, I prefer CPU-Z.
The applicationcould display N/A as the serial numberfor your motherboard. You may even see this section grayed out.
This means thememory manufacturerdid not program the information about serial number into the SPD chip.
In that case, you need to check the label on the memory stick physically.
Check the Memory Stick Label
The label contains all the necessary details about your RAM. This includes RAM speed, frequency,Memory timings, memory rank, and most importantly, serial number.
To check the label on the memory stick, you first need to remove it from the motherboard.
Once the RAM is out of the board, check for a label. This will have several writings.Check for numbers or writingsnear the bar/QR code. Number/writing under the code is your RAM’s serial number.
you may also use a barcode or aQR scannerfrom your phone to get the serial number.
When checking for the serial number, ensure that you don’t confuse it with the product model number. These are unique.
RAM with identical specificationsmay have the same product model. Serial numbers, on the other hand, are completely unique.
To distinguish the two, check for writing like 8G,16G, or 32Gdepending on the memory capacity of the product model. It may also have itsRAM Frequencywritten.
