[QUOTE="bobtomay, post: 1572428, member: 24160"] Lower CL timings = faster memory = higher price. With the particular work you have mentioned, you "might notice" an improvement with the lower CAS ratings. None of the part numbers match anything Kingston recommends for your Mac. They may all work, could be none of them will work. There is an issue of memory not working at the lower 1.35 volts. We recently had a member (was either in Sweden or Poland I think) that had purchased an upgraded RAM from the local Apple reseller with his new Mac - wouldn't work - they actually replaced his Mac twice before they figured out the issue was the 1.5v RAM they had been putting into his computer. Down to your issue - no Apple reseller close - can you walk in to that shop - if it doesn't work, what is the return policy of that store? If you can walk in - I'd carry the MBP with you and try the Blue modules right there in the store. The higher end modules will have both a lower CAS rating (CL) and typically will run at a wider range of voltages. These are what the overclockers are buying. I'm personally not a fan of the "value ram" from any manufacturer and don't recommend it unless the manufacturer states it will work in a Mac and the user of that Mac doesn't do much of any CPU/memory intensive work on their machine - purchasing "value ram" not specifically for a Mac is where you're going to see the highest percentage of incompatibility.
