Targeted upgrade for the 24‑inch iMac (Early 2009)
This 8 GB kit (2 × 4 GB) of DDR3‑1066 CL7 SO‑DIMM memory is built specifically for the Apple iMac “Core 2 Duo 2.93 24” Early 2009 (model MB419LL/A, A1225). It matches the original 1.5 V unbuffered, non‑ECC specification so the system recognises the modules without configuration changes.
Fits the two factory SO‑DIMM slots
The iMac ships with 4 GB across two slots; this pair occupies the remaining sockets and brings total memory to the platform maximum of 8 GB. No heat spreader is included, keeping the low‑profile form factor required by the slim all‑in‑one chassis, and the 204‑pin DDR3 interface aligns with the board’s native memory controller.
Replaces the stock 2 GB modules when all four
Builders who have already filled the first two slots with 2 GB sticks can swap them for this 4 GB pair to reach the 8 GB limit in a single step. The upgrade is worthwhile when the machine runs memory‑intensive macOS versions or creative workloads that exceed the original 4 GB; it does not benefit systems that cannot address more than 4 GB total.

商品問答
Does the DDR3 1066MHz CL7 timing limit bandwidth under sustained workloads?
The kit runs at 1066 MHz with CL7 7-7-7 timing, so sustained throughput is capped by that DDR3 8500 specification.
How much heat or power draw should I expect from these unbuffered SODIMMs running all day?
Each 4 GB module operates at 1.5 V without a heat spreader, so thermal output and power draw are low for typical all-day use.
My iMac currently has two 2 GB sticks installed — do I need to remove them before adding this 2×4 GB kit?
Yes, the system has two slots total and maxes at 8 GB, so the existing modules must be replaced with this pair.
