4GB DDR3 1333 desktop memory

This 4GB DDR3 SDRAM module runs at 1333 MHz with CL9 latency and 1.50V operation. It uses a 240-pin unbuffered DIMM form factor and non-ECC design. The stick is suited for upgrading older desktop systems that accept DDR3 memory.

Fits standard DDR3 desktops.

The module targets desktop PCs with DDR3 slots that support PC3-10600 speeds. It will not fit laptop SO-DIMM sockets, nor does it provide error correction required by some server or workstation boards. Buyers needing ECC or smaller form factors should look elsewhere.

Single 4GB 2Rx8 density

The kit consists of one 4GB module organised as 2Rx8, delivering 4GB total capacity in a single slot. This density determines whether the board can recognise the full amount, so verify the motherboard supports 4GB DDR3 ranks before purchase.
