Hey all. First post here, just wanting to make sure of a few things, as I'm not very experienced in overclocking in general, and have no previous experience with C2D/Qs

I am running an Core2 Duo E4400, with a Zalman 9700, on an Asus P5K SE, at 3.33 Ghz (333 X 10) , currently. Now for questions

To get the Cpu to overclock this far, I'm setting it at 1.45v in the BIOS. The cooling is quite capable of handling the extra heat, running at 57-8 degrees on Orthos after a few hours. I'm just wondering if it's safe to run it at this high of a voltage?

Idling on the desktop, the Vcore shown in CPU-Z and core temp is lower than my setting in the BIOS (hovering around 1.42v) and under full load, it shows as 1.368v.
Is this level of droop in voltage normal for this motherboard?

Would I be able to run it at a higher Vcore, and achieve a higher OC, since the actual voltage going through the CPU is lower than what I tell it to do in the BIOS?

Also, In the future, probably ~ 6 Months, I intend to upgrade to a quad core CPU. Would this motherboard be decent for overclocking The current generation of Intel quads? Would it be better to wait and go for a 45nM quad core instead? What kind of overclocks would I be able to expect on this cooling that I have, running quad core?

Thanks in advance all.

SE is not a good overclocker. P5K vanilla is. Or Deluxe or Wifi.

P35 is the best quad overclocker. Is P5K P35? You tell me.

On air, up to 1.5v is safe. If you have good air cooling, that 9700 is good. Not the best air cooler.

I don't think that's how you measure vdroop. You should compare the differences between load and idle temps in the SAME program. Speedfan, I presume. Provided you disabled everything in bios
