I put together a rig with the 805 D on an ASUS P5P800, so I could keep my x850 XT PE agp card and use my old DDR memory. With watercooling I was able to get to 3.4 GHz totally stable under stress for 8 hours. Anything more and I got bluescreens galore. I'm using Corsair XMS3200 DDR400 memory rated at 2.0 CL.

To try to eck more out of the motherboard, I put a fan on the northbridge heatsink that lowered the temp considerably, but I couldn't get anything more out of the chip. I tried raising the voltage to levels similar to what the guys did in the Tom's Hardware article on the 805 D, but the motherboard did not like that at all.

Somebody mentioned in another thread that the regulation on the P5P800 isn't good enough to get a decent overclock out of the 805 D, and that's probably right considering it's a bargain board. I'd just like to see some other people weigh in on what they got with this board and this processor, just to find out if it's really the power regulation that's putting the choke on everything.

I forgot to mention that I'm using a SilverStone 460 watt powersupply with an old style ATX 20 pin connector. At the same time when the computer's working (graphics, hard drive, etc.) I can hear little electrical noises from the power supply that match the hard drive noise and 3d happening on the screen. Anyone think that might be a problem?

THE WORLD NEEDS MORE 805 THREADS,
DON'T ACT LIKE YOU DON'T LIKE READING THEM.
DON'T ASSUME I HATE YOU GUYS FOR POSTING THIS,
JUST ASSUME I WANT TO DO YOU HARM UNSPECIFICALLY.

Ok... You sure it's not your memory thats cousing problems? you set the divider to allow your memory to run at a stable frequency?

I don't know anything about that processor but I own that exact board and I can tell you the amount of power a p4 530 3.0e uses at 3.9ghz means that on that board with that powersupply you cannot expect to go past 3.9ghz on a single core... and you are running a dual core close to those speeds, keep that in mind. Also, you take a look at your vcore voltage at the time you get a bluescreen? you might notice at full load the voltage might drop to dangerously low levels, also the northbridge on that board can't have it's voltage increased so it will start becoming unstable when you raise the fsb past 266.

Does this info help you understand where you stand as far as how much you can expect to push that system? If so great if not.. well I tried :p 

*Edit* Just Remembered, if you increase the cpu voltage past 1.55v you will find that even one of those huge zalman coolers won't keep the processor under 70C so you will need watercooling.
