This DFI board is simply amazing. It is 1.2875 CPU-NB voltage and 1.290 NB voltage
The key to NB stability actually lies in CPU voltage.
To prove my point, I could do 3.8ghz at 1.424v and run small fft all day and night with no problems. However, I would fail a blend test even at stock 2000mhz NB. Now when I bumped my CPU voltage up one notch to like 1.45v (droops to 1.44v under load) I could pass a blend test finally. I started slowly upping my NB until it wouldn't boot. It didn't POST at 2800mhz. So I cleared CMOS and backed down to 2600mhz and it ran blend for quite some time. In my opinion 2 hours blend is more than stable and I'm kinda scared to let it run any longer :S
I got lucky on this CPU. It is a later batch. Even though it doesn't unlock, it overclocks really really well. I could probably get 4ghz if I wanted, my load temps right now are 42 degrees with a mugen 2
I really don't want to go higher as it is already faster than I need it lol. I like to be sensible with overclocking. I just need to add a fan to my NB as it run close to 60 which is too hot for my liking.
