I'm looking to upgrade the RAM in my MBP 13" i7 2.8 to 16GB.
I saw a youtube video HERE where the guys states @25 sec(ish) that the timings need to be 9-9-9-24.

The RAM I'd like to use is Corsair Vengance SO-DIMM. The 8GB (2x4GB) kit has CAS of 9-9-9-24 LINK and I have seen a review stating it works OK in an MBP.
The 8GB sticks of the same are 10-10-10-27, so if I want 16Gb I would use 2 of these. LINK

My question is this: Does the Latency actually mean the RAM won't work at all? Or not as fast as it might? Or be unstable?

Many thanks.

Mine's got new kit of ram with different Latency and have had no problems whatsoever. Never heard of this giving trouble to people neither.

Your MBP will run slightly slower, but you won't notice it unless you run benchmarks. The RAM timings are stored in tables in the memory chips, along with other manufacturer's data. The system reads the tables and the memory controller will adjust its timings accordingly.

Thanks guys.

The Ram arrived today and I installed it.

About is now showing 16gb running @ 1600 Mhz. Graphic memory is up to 512mb too.

I also bought a 240 GB SSD.:)
