I recently bought a a pair of DDR3-1066 SODIMMs to upgrade a Mid-2010 MacBook Pro.
On the packaging for the memory, it says "Compatible with MacBook Pro: Mid-2010, Early-2011, Late-2011". However, according to Wikipedia, the 2011 models require DDR3-1333.
What would happen if somebody bought this memory and installed it in a 2011 MacBook Pro?
Would the memory run at 1333 speed (and if so, could this cause issues)? Or would the machine slow down to accommodate the slower RAM?
Edit: The memory is Corsair CMSA8GX3M2A1066C7. A picture of the packaging is below.
Is it really true that Corsair is recommending memory of the wrong speed?
