RAM Compatibility?

the specs are compatible with your 2011 MBPs so you should be fine

 

The RAM is compatible. The Kingston Value RAM does not mean poor performance. It has the same CAS timing as the factory Apple RAM, OWC, Samsung, etc. The CAS latency the RAM is capable of is just not as aggressive as their other RAM. Mac's don't have a BIOS where you can adjust your RAM timing. Kingston is also doing this to differentiate from their HyperX extreme performance RAM with faster bus speed and more aggressive latency. The MBP will take advantage of faster speed if it has PnP. The SNB MBP's will do 1600MHz.

I've tested the Kingston Value Memory 16GB kit (8GB x 2) in my 2011 15" Macbook Pro with Rember and its passed 4 cycles without issue.

Hi
I bought Kingston Value Ram ( 2x 4GB SO-DIMM 1333 mhz cl9 ) month ago to my brand new Macbook Pro 2.3 gh 17". It worked - that's what I thought.

After a week or two, strange things started to happened - apps started to crash, macbook had problems with waking up ect.

I thought is a system/driver problem like it almost always does.
I have re-install system many times, switched to lion, switched back to snow reset PRAM, SMC ect.

Then I thought - maybe it's the Kingston Value Ram.

I switched to ELIXIR and I don't have any of problems.

If I ware You I would not try Kingston Value Ram.
