Well, I switched out the ram in my new Alubook from the standard two 256 dimms to a total of 2 gigs of ram from OWC. Now I was assured that the ram is the same specs as Samsung and there is a life time warrenty, so i am not too worried there. and that the CL 2.5 was accurate. But I am having a few troubles that is making my work suffer or actually just me! Firstly my computer doesnt seem as fast as it was. One major symptom is that when I right click for context sensitive menu. I get BEAcHBALLED! I hate that and was happy when i first got the powerbook, that i never had that happen. But it seems to me that after the ram change, I lost some speed when i thought that I would gain! Now during this time I also installed alot of apps. So i question the slow down to either bad ram. or my HD slowing down for some reason. As always I am hoping that the minds and experience of the Macrumors members have the answers.
