Been playing with an Asus P5N-D and having a terrible time getting it to overclock past a 1500FSB. I increased the NB voltage, the SB voltage and could get to 1550, but the system or NB would idle at 45C and really soar when running orthos 55C or higher.

Anyway I was researching trying to find out what the heck the HT voltage option was in Bios and what it did. I found out it is another name for the CPU VTT voltage, think it showed up here in another Asus MoBo thread.

Anyway, increasing the HT voltage really helps the stability and the ability to run lower NB and SB voltages. With the CPU at 1.35 volts in bios, 1.31 volts in Hardware Monitor and AI Suite, CPU VTT (HT) at 1.5 and NB at 1.3 I am now currently running a 1610 FSB stable. Woot! Or in other words I now have a 2.81GHz E6300. Idle temp for Core0, which runs the hottest is up to 54C. Running Othros as I type this.

Just thought I would share in case anyone else had this board and was having difficulty overclocking it.
