2GB DDR3 desktop module

This single 2GB DDR3 DIMM runs at 1333MHz with CL9 latency and 1.5V operation. It is an unbuffered non-ECC module built to JEDEC PC3-10600 specification for desktop and workstation platforms.

240-pin unbuffered DIMM

The 240-pin form factor fits standard DDR3 desktop slots without requiring registered or buffered memory support. Installation uses no special tools and the module operates at the standard 1.5V so no voltage adjustment is needed in the BIOS.

JEDEC compliant sustained operation

Every module is tested to meet JEDEC and RoHS standards for reliable long-term use. The CL9 timing at 1333MHz delivers consistent throughput during extended multitasking sessions without thermal throttling or voltage drift.

Questions about this item

Does the 2GB DDR3 1333 module hit a capacity wall before speed or latency become the bottleneck under sustained workloads?

The 2GB limit is the first constraint you will reach; once the operating system and applications fill that space the system must swap to storage, which is far slower than the PC3-10600 CL9 data rate.

How much heat or fan noise does a single 1.5V unbuffered DIMM add when the PC runs all day?

The module draws only 1.5V with no heat spreader, so it adds negligible warmth and zero acoustic output; any extra fan activity comes from the CPU or GPU, not from this stick.

What must the desktop already have to accept this 240-pin non-ECC UDIMM?

The motherboard needs a free DDR3 240-pin slot that supports unbuffered non-ECC memory at 1.5V; the board’s chipset and BIOS must also recognise 1333MHz PC3-10600 modules.
