System-Specific DDR3 Upgrade

This 8 GB kit contains two 4 GB modules rated at DDR3 1333 (PC3 10600). It is intended for Dell-compatible iMac systems that require this exact memory specification. Buyers who need a different capacity, speed or form factor should look elsewhere.

Sustained Operation

The modules run at the standard JEDEC DDR3 1333 frequency without overclocking headroom. Under continuous workloads they maintain rated throughput and latency because no higher speeds or tighter timings are specified. Builders expecting enthusiast-grade headroom will not find it here.

Deciding Specification

The single figure that determines fit is the PC3 10600 rating, which equals DDR3 1333. If the target iMac calls for a different DDR3 speed grade or a later DDR generation, this kit will not be compatible.

Questions about this item

How much power does the DDR3 1333 kit draw when the system runs all day?

Standard DDR3 1333 modules operate at 1.5 V and consume only a few watts each, so the pair adds minimal load to the power supply during continuous use.

What must my iMac already have for this 2×4 GB kit to work?

The Mac needs two free DDR3 SO-DIMM slots and a firmware that accepts PC3-10600 memory; the modules are notebook-sized sticks, not desktop DIMMs.

Will these PC3-10600 modules run reliably alongside the original memory I keep installed?

The system will clock all installed DDR3 to the lowest common speed, so the original memory and the new kit run together at the same reduced rate.
