Compatibility check for the 17-inch MacBook Pro

Before ordering, confirm that the target machine is the 17-inch MacBook Pro "Core 2 Duo" 2.8 from Mid-2009 with model identifiers MC226LL/A, MacBookPro5,2 or A1297. The system must accept 204-pin DDR3 SO-DIMM modules running at 1066 MHz. Verify the board has two available slots and supports a maximum of 8 GB total capacity. Ensure the existing configuration can accommodate unbuffered, non-ECC memory with CL7 timing at 1.5 V.

Kit contents and practical effect

The package delivers two 4 GB sticks that together raise the notebook to its 8 GB ceiling, enabling smoother multitasking and faster application switching on the supported platform. Dual-channel operation is achieved when both slots are populated with matched modules. No heat spreaders are included, so the sticks fit the slim SO-DIMM profile required by the 17-inch chassis. Product appearance may differ from reference images.

Should I choose the 8 GB kit or a different capacity for my MacBook Pro 2.8 17" Mid-2009?

This 8 GB kit (2 x 4 GB) matches the maximum memory supported by the MacBook Pro "Core 2 Duo" 2.8 17" Mid-2009, which has two slots and an 8 GB limit.

What does the PC3-8500 1066 MHz rating mean once the modules are running in my MacBook Pro?

The memory will operate at 1066 MHz with CL7 timing at 1.5 V, delivering the standard DDR3-8500 bandwidth for that system.
