This article covers CT2K4G3S1067M [8GB Kit (4GBx2) DDR3-1066 (PC3-8500) CL7 SODIMM 204pin for Mac].

Overview

The Micron CT2K4G3S1067M is an 8GB DDR3 memory kit consisting of two 4GB modules. It uses the SODIMM 204-pin form factor, making it suitable for laptops and compact desktops, with explicit compatibility for Mac systems. The memory runs at 1066MHz (PC3-8500) with a CAS latency of CL7, which was standard for the DDR3 generation. This kit is specifically designed for older Mac models such as MacBook, MacBook Pro, iMac, and Mac mini from around 2009 to 2012. Upgrading from the typical 2GB or 4GB to 8GB can significantly improve system responsiveness, especially for web browsing, office work, and light multitasking. While DDR3 is now a legacy standard, this product serves a niche audience looking to extend the life of their aging Macs without investing in a new machine. Priced at around ¥13,499 (as of August 2026), it is more expensive than used DDR3 kits but offers the reliability of a new, Mac-certified product from a reputable manufacturer.

Compatibility Guide

Form Factor: SODIMM 204-pin — fits laptops and some all-in-one desktops (e.g., iMac). Not compatible with desktop DIMM slots (240-pin). Memory Standard: DDR3-1066 (PC3-8500) — operates at 1066MHz. Can be installed in slots rated for higher speeds (e.g., DDR3-1333 or 1600), but the system will downclock to 1066MHz. Platform Support: Mac models from 2009–2012 (MacBook, MacBook Pro, iMac, Mac mini) and any Windows laptop that supports DDR3 SODIMM. However, Mac-specific tuning may cause issues on some non-Apple systems. Capacity: 8GB kit (2x4GB) — dual-channel operation is supported if the motherboard has two slots and the chipset supports it. * Voltage: Standard 1.5V. Compatible with DDR3L (1.35V) slots, but the system will supply 1.5V, which is safe for DDR3L modules.

Product Info

The CT2K4G3S1067M is a genuine Micron memory kit, originally released around 2012. It remains available through retailers like . The price is approximately ¥13,499, which is higher than used alternatives but reflects the new-in-box condition and Mac compatibility guarantee. Warranty varies by seller; Micron typically offers a limited lifetime warranty on their memory products. Market positioning: entry-level legacy upgrade. It is not suitable for modern gaming or high-performance computing, but it is a reliable choice for extending the usability of older Macs.

Best Use Cases

Mac users with 2009–2012 models: If your MacBook or iMac feels sluggish with 2GB or 4GB of RAM, upgrading to this 8GB kit can breathe new life into the system. Ideal for web browsing, email, and light productivity. Budget-conscious users with a legacy laptop: If you have an old Windows laptop that supports DDR3 SODIMM and you want a reliable new memory kit, this could work — but verify compatibility first. Not recommended if you can find a cheaper generic kit. * Users who prioritize reliability over cost: New memory from a major brand like Micron offers peace of mind compared to used modules that may have unknown history. This is for those who want a drop-in solution without hunting for used deals.

Things to Consider

Mac-specific design: This kit is optimized for Mac systems. While it physically fits many Windows laptops, some users report boot failures or instability. Always check your motherboard's qualified vendor list (QVL) before purchasing. Speed limitation: If your system supports DDR3-1333 or higher, this memory will run at 1066MHz, potentially leaving performance on the table. For maximum performance, match the memory speed to your system's native support. Price vs. used market: New DDR3 kits are becoming scarce and expensive. A used 8GB DDR3 kit can often be found for ¥3,000–¥5,000. The premium for new-in-box may not be justified unless you specifically need Mac compatibility or warranty coverage. No future-proofing: DDR3 is obsolete for new builds. This purchase is strictly for extending the life of an existing machine. Do not buy this with the expectation of using it in a future PC. ## FAQ
Q: Will this memory work in a MacBook Pro 2011 (Early 2011)? A: Yes, the MacBook Pro 2011 supports DDR3-1066 SODIMM and can accept up to 8GB (2x4GB). Some models support 16GB, so check your specific model's specifications on Apple's support site. Q: Can I use this in a Windows laptop? A: Physically yes, but compatibility is not guaranteed. The kit is tuned for Mac systems, and some Windows laptops may fail to boot or exhibit instability. For Windows laptops, consider generic DDR3 SODIMM kits from Crucial or Kingston. Q: Can I mix this with DDR3L (low-voltage) memory? A: It is possible but not recommended. This kit runs at 1.5V, while DDR3L runs at 1.35V. Mixing them forces the system to use 1.5V for all modules, which may stress the DDR3L modules. For best stability, use identical voltage and timing modules.
