Simmtec, Inc 2x 4GB DDR3 1333 CL9 1.5V UDIMM

SKU CH-CTS4-7FZ5M

Two 4 GB DDR3-1333 CL9 UDIMM modules at 1.5 V for desktop upgrades

  • Total capacity4 GB
  • Rated speedDDR3 1333 (PC3 10600)
  • CAS latencyCL9
  • Dual-channel kit doubles bandwidth for smoother multitasking
  • CL9 latency at DDR3-1333 keeps response times tight
  • 5 V standard voltage fits most desktop boards
  • 240-pin UDIMM form factor installs in seconds

Kit details

This kit provides two 4 GB DDR3 UDIMM modules rated at 1333 MT/s with CL9 latency. It suits owners of older desktop platforms that use 240-pin slots and 1.5 V operation. The matched pair enables dual-channel bandwidth on supported motherboards.

Upgrade path

It replaces single modules or slower DDR3 kits when the board accepts PC3-10600 speeds. The jump is worthwhile when the system currently runs one stick or memory rated below 1333 MT/s. Builders needing higher frequencies or lower voltages should look elsewhere.

Questions about this item

Will these 240-pin DDR3 UDIMMs fit my desktop motherboard?

Yes — they are standard 240-pin DDR3 UDIMMs, the form factor used by most desktop boards that support DDR3 memory.

How do I install the two 4 GB modules correctly, and what step is often missed?

Align each module’s notch with the slot key, press down firmly until both side clips click into place, and ensure both sticks are fully seated so the system recognises the full 8 GB.
