Our sales department is always ready to guide you in your choice and to provide you with appropriate advice. We provide advice on frequently asked questions here:
Consider carefully which memory is suitable for your device. The memory module for your device must be of the correct type to function. You can find this in the specifications in the manual of the motherboard. Consider carefully which type of memory fits in your device.
SERVER / DESKTOP / NOTEBOOK
First of all, pay attention to the following rules of thumb:
|Desktop memory||DIMM (UDIMM)||UNBUFFERED||NON REGISTERED|
|Notebook memory||SO-DIMM||UNBUFFERED||NON REGISTERED|
|Server/Workstation memory||DIMM (RDIMM)||ECC BUFFERED||REGISTERED|
DIMM and SO-DIMM
Desktop memory and Server memory is also called DIMM
Memory modules for notebooks are indicated with SO-DIMM
However, each type of DDR memory has a different shape and a different number of connection points. These connection points are called pins. Different types of DDR memory cannot be combined with each other in one system.
(S)DRAM and SRAM
Modern computers almost always use dynamic RAM, the abbreviation for dynamic RAM is DRAM.
SDRAM is the current DRAM generation and can be found in almost every computer, smartphone or tablet.
The term SDRAM is followed by the addition DDR. We make a distinction between DDR-2 / DDR-3 / DDR-4
SRAM stands for static RAM and is often used in a computer as a CPU cache, a kind of memory aid for the processor in the computer.
In addition to the SDRAM type, it is also important to look at the clock frequency or clock speed of the memory. This is indicated in MHz (megahertz). A motherboard usually only supports a certain number of clock frequency types, so you have to buy memory that is supported by your motherboard.
It is recommended that you install RAM in pairs because this improves performance. If you have the choice, also choose two modules from the same manufacturer with the same specifications. For example, if you want a total of 8 gigabytes of main memory, you are better off buying two modules of 4 gigabytes than one of 8 gigabytes. This is advantageous because the motherboard can activate the dual-channel functionality this way, which improves the transfer speed.
Hard drive part number
If you are going to replace your hard drive, you can find the replacement item the quickest based on the item code that is on your hard drive.
There are multiple article codes and serial numbers on each hard drive.
In our webshop we usually use the item code that you can find here (1):
If you do not know this code, you can also search for a 'Bare Drive' (2) or 'Assembly' (3) Harddisk number
On our invoices, we usually use the serial number (4) that starts with 'CT:'
SSD and HDD
The most common drives are the HDD (Hard Disk Drive) and the SSD (Solid State Drive)
Unlike an HDD, an SSD contains no moving parts. The data is stored and read from memory chips, instead of a rotating magnetic disk. An SSD is therefore more advanced and faster than an HDD.
The storage capacity of an HDD is usually larger than that of an SSD in a comparable price range.
LFF and SFF
Hard drives come in various sizes. The most common ones are:
|LFF||Large Form Factor||3.5 inch|
|SFF||Small Form Factor||2.5 inch|
SAS / SATA and SCSI
Hard drives have different types of connections.
The most common ones are:
|SATA||This is mainly used with desktops and notebooks|
|SAS/SATA||This is mainly used with servers and workstations|
|SCSI||Precursor to SAS, was used in older-generation servers|
