Simmtec 8GB DDR3 1333 Kit

This Simmtec kit provides 8 GB of DDR3 memory in a matched pair of 4 GB modules. Rated at 1333 MHz with CL9 latency, the dual-rank UDIMMs operate at the standard 1.5 V. The 240-pin form factor fits desktop motherboards designed for PC3-10600 memory.

Who this suits and who should look elsewhere

Builders upgrading or repairing a desktop that takes DDR3 UDIMMs will find the speed and voltage match the platform requirements. The low-density dual-rank layout helps compatibility with many chipsets of that era. Buyers who need higher capacity, faster speeds, or ECC functionality must choose a different kit.

Deciding specification — DDR3 1333 dual-rank UDIMM

The single detail that decides fit is the DDR3 1333 dual-rank UDIMM specification at 1.5 V. Only motherboards that explicitly support this speed, rank configuration, and voltage will recognise the full 8 GB. Verify the board manual before purchase.

Questions about this item

Does my motherboard need a 240-pin DDR3 slot for this 1333 MHz kit?

Yes, each 4 GB module is a 240-pin UDIMM built for DDR3 1333 (PC3-10600) operation at 1.5 V.

Will these dual-rank sticks run with single-rank modules I already have?

The kit uses 2R8 dual-rank organisation; mixing ranks is possible but the system will run all channels at the slowest module's speed and tightest timings.

How can I confirm the memory is detected at the rated 1333 MHz CL9 after installation?

Enter the BIOS or use a tool such as CPU-Z; the SPD tab should show DDR3-1333, CL9 timings and 1.5 V for each 4 GB DIMM.
