How do you know what the latency of your RAM is? I just bought some from PNY, and it didnt mention anything of it on the box. Right now I have the latency set to 2 (was 3) in my BIOS, and there aren't any visible problems. I'm just wondering what kinds of issues I should be looking for (random freezing? video corruption? smoke coming out of the case?) Thanks for any insight.
