[SOLVED] Asus P6T Deluxe V2 overclocking - QPI

[6-core]

Im trying to oc my Asus P6T Deluxe V2 again. Last year I got a decent 980 in cb15. Now I cant get close to that, 900 at best. Im sure I did everything like last year.
How does QPI work regarding ocing? The higher the QPI.....? Or is it the lower the QPI.......? For my current oc it is at 7200gt but I think it benches lower like that, so I keep it on auto.
Can some please explain QPI throughput to me and its relation to ocing. Thanks.

Did you use CB15 again or the latest version of it?

Did you upgrade anything? HDD, SSD,....
Windows updated?
BIOS updated?

QPI is the connection between the northbridge and the CPU. The higher the better, but wouldn´t alter it.
