Dual-channel kit for desktop upgrades

This 4 GB kit contains two 2 GB DDR3 modules rated at 1600 MHz. It targets owners of older systems who need a straightforward capacity increase without changing platform.

240-pin unbuffered DIMMs at 1.5 V

The standard desktop form factor fits typical DDR3 slots and the non-ECC, unbuffered design matches consumer motherboard requirements. JEDEC-compliant chips from Micron, Samsung, Hynix or Elpida provide baseline compatibility.

Matched pair enables dual-channel operation

Installing both modules together activates the board's dual-channel controller for improved bandwidth. No extra software or configuration is required beyond normal BIOS detection.

Perguntas sobre este artigo

What speed does the DDR3-1600 PC3-12800 interface cap the memory at in practice?

The modules run at 1600MHz with a PC3-12800 bandwidth rating, delivering that data rate when the motherboard supports the JEDEC standard.

What physical slot and pin count does this 240-pin UDIMM need to fit a desktop motherboard?

It requires a standard DDR3 240-pin DIMM slot on a desktop board; the notch position matches the DDR3 keying so it only seats one way.

How is the kit installed and which step do builders often get wrong?

Power off the PC, open the case, align the notch on each 240-pin stick with the slot key, press down firmly until both side clips click shut, then power on to confirm 4GB is detected.
