Computer Memory Solutions CM256645300SO 4GB (2x2GB) DDR2 667MHz PC2-5300 SODIMM memory upgrade

Purpose-built upgrade for mid-2007 iMac

This 4 GB kit delivers two 2 GB DDR2 667 MHz SO-DIMM modules designed specifically for the Apple iMac (Mid 2007). The unbuffered, non-ECC memory operates at 1.8 V with CL5 timing and uses major-brand chips. It targets owners of that model who need a straightforward capacity increase without compatibility guesswork.

Capacity and headroom

The kit provides 4 GB total across two 200-pin sticks, matching the PC2-5300 speed rating. The supplier notes the Mid 2007 iMac can address up to 6 GB when populated with a 4 GB and a 2 GB module in its two slots. This kit fills both slots with 2 GB each, leaving the upper 2 GB of the system's maximum addressable memory unused.

Thermals, noise and power

These modules have no heat spreaders and draw power only from the SO-DIMM slots at the standard 1.8 V DDR2 level. They add no moving parts, so acoustic output remains unchanged. Power consumption stays within the original platform's memory-bus budget, requiring no extra cooling or power-supply headroom beyond what the iMac already provides.
