Compatible MacBook Pro upgrade
This 4 GB DDR3 SO-DIMM is built for the Apple MacBook Pro "Core 2 Duo" 2.53 13-inch (Mid-2009). It installs in a 204-pin slot and runs at 1066 MHz with CL7 timing. The module is unbuffered, non-ECC and uses major-brand chips at 1.5 V.
Replaces factory 2 GB or 4 GB modules
The MacBook Pro 5,5 (A1278) ships with two sockets and a 4 GB ceiling when updated to Boot ROM MBP 51.007E. B05 and Mac OS X 10.6. Swapping the original sticks for this 4 GB unit lets you reach the 8 GB maximum in a 2 × 4 GB configuration. Buyers who need more than 8 GB total cannot use this platform.
Steady operation at rated speed
Rated at PC3-8500 with 7-7-7 timings, the module maintains its 1066 MHz data rate without a heat spreader. Unbuffered DDR3 at 1.5 V keeps power draw low during extended workloads such as video encoding or virtual machines. No thermal throttling is expected under normal laptop airflow.

이 상품에 대한 질문
Will this 204-pin DDR3 SO-DIMM fit the memory slots in my MacBook Pro 13" Mid-2009?
Yes, the module matches the 204-pin DDR3 SO-DIMM form factor used by the MacBook Pro "Core 2 Duo" 2.53 13" (Mid-2009) and seats directly into its two SO-DIMM sockets.
What is the correct way to seat the module so the Mac recognises the full 4 GB?
Insert the stick at a slight angle until the gold contacts disappear, then press down firmly until both side clips click — the common mistake is stopping at the first click and leaving the module partially seated.
When should I consider replacing this memory stick?
Replace it if the Mac fails the memory test at startup, shows repeated kernel panics, or will not boot after a macOS upgrade — otherwise the module has no moving parts and requires no scheduled maintenance.
