Targeted iMac Upgrade
This kit delivers 4 GB of DDR3 memory in two 2 GB SO-DIMM modules built for the 21.5-inch Mid-2011 iMac with a 2.5 GHz Core i5. Unbuffered, non-ECC chips run at 1333 MHz with CL7 timing at 1.5 V. The 204-pin form factor fits the factory slots without modification.
Ideal for Mid-2011 Owners
Owners of the specified iMac model seeking a straightforward capacity increase will find guaranteed compatibility and a lifetime warranty from the manufacturer. Systems already at the maximum supported memory or users needing ECC registered modules should consider other options.
Capacity and Limits
The 4 GB total spreads across two ranks per module, providing the density this platform accepts. Everyday multitasking and period-correct applications run comfortably within this limit. Workloads demanding larger datasets or modern virtualisation will exhaust the available headroom quickly.

이 상품에 대한 질문
My iMac currently has 4 GB of memory installed; will adding this 4 GB kit bring the total to 8 GB?
Yes, the kit adds two 2 GB modules for 4 GB total, so a system that already has 4 GB will reach 8 GB once both slots are filled.
Does the CL7 latency of these modules match the timing of the original Apple memory in the Mid-2011 iMac?
The modules run at CL7 with 7-7-7 timing at 1333 MHz, which is the standard specification for this iMac model.
After installation, how can I confirm the Mac recognises both 2 GB sticks at 1333 MHz?
Open About This Mac → Memory; it should show 4 GB total with two 2 GB DDR3 1333 modules listed.
