I'm wondering, has anyone noticed if their AI7 clocks higher (stable figures only) if you use tighter timings versus looser timings? I know that seems counterintuitive but that's what I've discovered after going through another round of overclocking after switching to the 1.6 Beta BIOS.
Background:
With my setup using BH-5 Kingston HyperX, I've found that with 2-4-4-8 or 2-3-3-7 or 2.5-3-3-7 timings with 5:4 divider, I can only reach max stable (prime95 24hr) OC of 3.1GHz although I can clock up to 3.5GHz unstable. After much headbanging (you DON'T want to know how long... ) I've found that with 2-2-2-5 timings and 5:4 divider I can run 100% stable at 3.5GHz. Yeah I know, WTF is going on? If I use a 1:1 ratio, I can overclock higher using loose (2-4-4-8) timings. If I swap out the AI7 for an IS7 keeping all the components, I can stable OC higher using looser timings versus tighter timings so it's not an issue with my CPU or memory.
Anyhow, I am definitely NOT complaining about this latest find as it gave me a huge performance jump. I'm just wondering if this is particular to my setup or if other people have noticed the same thing.
