SO-DIMM PC2-5300 Memory Gets Your Mid-2000s PC Up and Running

After the launch and subsequent adaptation of the first RAM modules that used the first DDR standard, the memory industry saw rapid improvements afterward. The succeeding standard was DDR2 and promised faster bus speeds and bandwidth than its predecessor, promising twice as much MHz bus speeds and more GB capacity.

What Is PC2-5300 DDR2-677 MHz Memory?

  • PC2-5300: There are two different designations for this particular 200-pin module. PC2-5300 denotes the industry name for this type of DDR2 SDRAM, where PC2 indicates that the RAM uses the DDR2 standard while 5300 is the module name. This unbuffered laptop memory that uses the SO-DIMM form-factor.
  • DDR2-677 MHz: DDR2 denotes the standard the SODIMM module uses. The 677 MHz measurement tells you the total front side bus speed of the DDR2 SDRAM. Depending on the motherboard, it could support a maximum of 8 GB DDR2 memory, which means you will need two 4 GB sticks in a dual-channel motherboard to get 8 GB of total DDR2 RAM.
  • SODIMM: This form-factor is called "single outline dual in-line memory module". This is the standard physical design for laptop memory and small desktops like all-in-one computers. They are shorter in length but taller in height than desktop DIMM memory and have 200-pin terminals used to interface with the motherboard through the SODIMM slots. Its physical attributes promote slim and streamlined laptop designs because it is installed at a flat position so it lays against the motherboard. 

What Can I Do With PC2-5300 Memory?

  • Run Legacy Applications: Despite newer standards being available, some people still use this type of SODIMM memory to run a computer because their work requires software that only runs with older hardware. Some factories or government offices still use laptops with 4 GB of DDR2 PC2-5300 memory for particular software to run manufacturing machines or to do particular governmental tasks.
  • Restoration Project: You can also get an old laptop up and running with this type of memory, especially those released before 2010. But first, you need to check the motherboard specifications on your laptop of choice to ensure compatibility. You will usually find it in under the Memory category; expect to see a range of frequencies like 1333/1066/800 MHz. This means that the motherboard can take any DDR2 sticks running at those clock speeds.
  • Desktop Use: SODIMM RAM can be used with desktop motherboards too. Some ITX motherboards have SODIMM slots on them. But for DIMM-only motherboards, you can use a SODIMM to DIMM adapter. It's shaped just like a DIMM stick but has SODIMM slots that allow you to mount a SODIMM stick.
