Four green DDR3 SODIMM sticks with black chips in a clear tray

Timetec

Timetec 32GB (4x8GB) DDR3 1066MHz CL7 204-Pin SODIMM Laptop RAM

SKU CH-AYBR-AR272

A 32 GB kit of four 8 GB DDR3 1066 MHz CL7 SODIMM modules for upgrading a 27-inch 2009 iMac

  • Capacity32GB (4 x 8GB)
  • Type204-Pin DDR3 SO-DIMM
  • SpeedDDR3 1066 (PC3 8500)
  • CAS LatencyCL7
  • Voltage1.50V
  • ECCNo

Capacity 32GB (4 x 8GB)

  • 32 GB kit expands multitasking headroom for demanding workflows
  • CL7 latency at 1066 MHz keeps data moving with minimal delay
  • 5 V DDR3 modules run cool and stable in compatible systems
  • Four 8 GB sticks fill all slots on supported 27-inch iMac (Late 2009)
  • 204-pin SO-DIMM form factor drops straight into the memory bay

Capacity and Fit

This 32 GB kit contains four 8 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 latency. It is built for the 27-inch iMac from late 2009 identified as iMac11,1 and uses the 204-pin form factor required by that system.

Sustained Load Behaviour

The modules run at 1.5 V and are unbuffered non-ECC dual-rank parts based on 512x8 ICs. Under continuous multitasking workloads the CL7 timing and selected ICs maintain stable throughput without throttling or error correction overhead.

Thermals Noise and Power

Operating at the standard DDR3 voltage keeps power draw predictable for the iMac's original cooling design. The low-profile 30 mm height allows unrestricted airflow inside the compact enclosure, so fan speeds and acoustic levels remain unchanged during extended use.

Questions about this item

How much power and heat will four 1.50 V DDR3 modules add to an iMac running all day?

Each 8 GB stick runs at 1.50 V DDR3 1066; the four-module kit draws standard DDR3 power for that voltage and speed, so thermal load matches other PC3-8500 SODIMMs in the same slots.

What tools or parts do I need before installing this 4 × 8 GB kit in a 27-inch Late 2009 iMac?

Only a screwdriver to open the memory door; the 204-pin SODIMMs are plug-and-play with no extra cables, adapters or firmware updates required.

Will these CL7 1066 MHz modules work alongside the original 1067 MHz memory Apple shipped in the iMac11,1?

Yes — the kit is rated DDR3 1066/1067 PC3-8500 CL7, matching the factory speed grade, so the system will run all populated slots at the common 1066 MHz frequency.
