I purchased the Patriot memory (specs below) for my MBP, 2.33 ghz, installed it and tried to power up and all I got was a black screen. I thought the specs matched perfectly but apparently something went wrong. PC2-5300 (667MHz) Data Rate 200-Pin Dual in-line memory module Non-ECC Unbuffered 2 Rank Double-sided module 7.8US Refresh Interval (8192 CYCLES/64MS) 1.8V Power Requirement Auto and self refresh capability PCB height: 1181 (mil) Serial Presence-Detect (SPD) 100% Tested Lifetime Warranty RoHS Compliant http://patriotmemory.com/products/detailp.jsp?prodline=3&catid=2&prodgroupid=37&id=614&type=5 Any thoughts? Did I miss something? Thanks a bunch!!!
