Hi, Corsair just released new XMS-2700LL SO-DIMMs for laptops with a CAS latency of 2. Apple's hardware documentation says that PowerBooks run at CL2.5. I am assuming that if I take out the CL2.5 RAM and replace it with CL2 RAM, it will run it on the new timings based on the SPD chip in the RAM. Am I right in saying that or is it locked to run at 2.5. Is there a firmware command to set RAM timings?
