Hi, I have an early 2011 MBP 13" (i5). According to crucial, I need: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.35V • 512Meg x 64 • lead free • halogen free • for Mac • Part #: CT3309331 I've noticed a few sellers on ebay mention that the DDR3 204-pin RAM they are selling isn't compatible with Apple. Which of these specs are critical and which are not? For example, would this kit work? http://www.amazon.com/G-SKILL-204-P...-8GBSQ/dp/B004U3MQQY/ref=cm_cr_pr_product_top Q1: The main difference is the voltage is listed as 1.5v instead of 1.35v. I assume 1.5v will work? Q2: If I see other RAM that's CL-11 instead of CL-9 does that matter as well? I know it CL-11 is slower, but assume it would still be compatible.
