MacBook Pro 13" 2009 memory upgrade
This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Mid-2009 MacBook Pro 13-inch model MB990LL/A. It targets owners of that specific notebook who want to reach the machine's 8 GB ceiling. The sticks are unbuffered, non-ECC and run at 1.5 V.
Sustained load behaviour
CL7 timing at 1066 MHz gives low latency for everyday multitasking and older macOS workloads. Major-brand DRAM chips and the absence of a heat spreader keep the modules within the notebook's thermal envelope during extended use. Lifetime warranty from the manufacturer backs long-term reliability.
Deciding specification
The kit is validated only for the MacBook Pro "Core 2 Duo" 2.26 13" (SD/FW) running Snow Leopard 10.6 with Boot ROM MBP 51.007E.B05. Systems lacking that ROM version or a different model identifier will not recognise the full capacity.

คำถามเกี่ยวกับสินค้านี้
How much power does the 1.5 V DDR3 1066 MHz kit draw under continuous load?
The modules run at 1.5 V with no heat spreader, so they draw minimal power and stay cool during all-day use in the MacBook Pro 13".
Does this 204-pin SODIMM set need any extra parts or firmware before it works in the Mid-2009 MacBook Pro?
No extra parts are required; the MacBook Pro must run Mac OS X 10.6 Snow Leopard and have Boot ROM version MBP 51.007E.B05 installed for the full 8 GB to be recognised.
Will the CL7 1066 MHz sticks run stably alongside the original 2 GB or 4 GB modules that came with the 2.26 GHz Core 2 Duo?
The kit is designed as a matched 2 x 4 GB pair for the two slots; mixing with older modules is not recommended because the system maxes at 8 GB and timing mismatches can cause instability.
