alright boy! now you need to tell me all your settings!
Tell me vcore, fsb, nb, sb, ht, all the ram settings and your temps!
Have you updated the bios to the latest, and do you have the latest drivers on the motherboard and graphicscard also have you overclocked the graphicscards

Then I will be able to help you!
This was a lot, but you can make it

Okay. I've been using these settings:
vcore 1.5 (tried upping it gradually with no improvement, so it's back to 1.5)
fsb 1423 nb/ht 1.48 sb 1.58

Sometimes my system will not boot to windows at all while overclocked - it tries to load the windows desktop and shuts down and reboots again and again until I remove OC settings in bios.

Overclocked, my CPU temps were 45c idle and 65c under full load with prime95 2.56.

I have not changed any ram settings. Using 4GB (2 x 2GB) Kingston DDR2 667. I checked it with memtest and it tested okay.

This is interesting. I just tried some experimenting and removed that ram and put in some older ram I have that is 2GB (2 x 1GB) Corsair DDR2 533. It will not even post while overclocked - gets to the ASUS screen and freezes until I shut it down. If I turn off OC in the bios, then it works fine.
Question: Are the OC settings you provided dependent upon having 800 speed memory? Or do you have any other ideas?

J_Smyth

Oh yes. Updated everything. BIOS 0601, Chipset drivers 9.46, NVIDIA driver 175.19.

The video cards are factory overclocked to 700MHz (vs. 600MHz stock) BFG 8800GT in SLI.

The settings I used was with 800mhz ram, but I think it should be okey anyways! About that you cant get to windows when overclocking, I had a similar problem with my new 780i, and the problem was that it didnt like 4gb of ram!:/ so I would recommend trying with only 2gb`s of ram!
And PLEASE get another cooler for your cpu! that is just to high temps on idle! you can run it like that for a while, but not to long! so get a zalman 9500 or something:P

I discovered the memory speed has nothing to do with it. It will sometimes boot up and I can play Crysis for hours, the next morning it will reboot several times before Windows will load. This is only when it is overclocked - no problems at 2.4MHz. I'm stumped. I will try using just 2GB memory and let you know. Also, I just installed an Arctic Freezer 7 Pro CPU cooler. I'll report new temps, too.

lol that Arctic Freezer 7 Pro has been fail for me.... i am thinking of getting something else.

good that you got some better cooling, but its not that good for overclockers:/ The sad thing about the Asus P5N-D is that it is quite unstable.. A other guy I talked to had it running at 3.2ghz for 3months and then suddenly it crashed and would not work properly..

I did have some problems my self, and what I tried was to pull out the battery, and all power, then letting it be like that for 2 hours and then put it back again. That will maybe work.. But no promises..

u also have to move the cemos jumper to the 2-3 pins when u remove the battery to reset everything.
