BTW, nice job getting your NB up to 3300mhz, that's just awesome!
I will when I get home. I'm at work right now and don't have access to my bios. However the CPU-NB VDD and CPU-NB Voltage are very important to achieving a high NB frequency, other than cpu temps itself.
CPU-NB VDD voltage adjustments shouldn't be necessary as I used AUTO up until 3300mhz in linx and have posted at 3600mhz NB. However, if you adjust your CPU-NB VDD voltage up it has the ability to become severely unstable and in a lot of cases not even post.
Conversely, the CPU-NB Voltage is the key setting for NB frequency. I use approx 1.55v on this setting, but the odd part is if you adjust the CPU-NB VDD voltage to appox 1.48v it's no longer in red on the CPU-NB voltage @ 1.55v. Although, not stable at all and won't even post @ 3300mhz for me until I drop down the CPU-NB VDD and up the CPU-NB. Actual NB voltage doesn't seem as important to NB frequency as the CPU-NB and CPU-NB VDD voltages.
Your results may vary b/c I'm actually using some spare i7 ram I have (dominator gt's) until I get iandh's ocz's. Apparently i7 ram isn't that great of a choice on amd 790's.
When I get home I'm going to start playing more with the NB voltage and ram dividers to see what effects those have.Edited by NCspecV81 - 11/10/09 at 7:40am
