I recently bought 512 of RAM made by Kingmax, I believe. Popped it in, and 2 days later, I get crashes and kernel warnings. I cannot play Ages of Myth without a crash. Safari crashes frequently. I tested the RAM using TechTool Deluxe and it said the RAM was good. However, I googled 'bad RAM' and read that these tests are unreliable. Is there a way I can be certain if its really the RAM?? Help, my 1.25 PB has never behaved like this!
