Hey, really hoping someone can help as I'm really starting to tear my hair out over this.

I have just bought the Aus P5N-D mobo and I'm running into problems. I was using bios 0402(latest) and had my Q6600 OCing to 2.7Ghz but then hit a wall and it wouldn't boot into windows. I tried upping the FSB significantly to 1600, in case there was a hole in my cpu's OCing ability, with my ram running in sync mode. Again I didn't make it into windows and ever since when I take my FSB & Memory Config settings off Auto, even if I leave them on default settings (1066Mhz & 800Mhz) they revert back to Auto on the next boot up.

I can change other settings and they'll stick so I'm pretty confused. I've changed from 0402 to 0304 to see if this would help but same results. I still have a working system but seemingly without the ability to overclock.

I'd really appreciate any help you guys can give me.

My setup:
ASUS P5N-D
Q6600 GO
4GB OCZ Vista Performance Gold DDR2 PC2-6400
Xpertvision 9600gt Sonic
250GB Samsung HDD
Samsung DVD Writer
OCZ 700W GXS PSU
CoolerMaster Elite 330
XP Professional

UPDATE: Solved the problem, I removed the battery and the GPU(as it was in the way) and reset the CMOS jumper for 10 seconds. Put everything back and powered on and now as good as gold.

Have my Q6600 GO running at 3Ghz (Vcore : 1.325, Vmem: 2.1, Vht: 1.3,Vnb: 1.3,Vsb 1.5), 20 mins into Prime95, no errors, temp sub-60C.

Think I can probably take Vcore down a little but still not too hot as is.

Wanna do me a favor and next time you get the chance to place things back on auto, put the fsb back on 266 and vcore on auto, leaving speed step off, and run core temp version 0.96.1 and post the VID value? Then run prime 95 and watch the core temp VID value and make sure it doesnt chance when your processor is under load!

Just gathering a bit of info from various people about their q6600's! So many VID's and so few people having multiples of them with different VIDs to pit against one another to see if that factor matters or not to OCing!

Alright - Sup guys - Heres a lil help if your still stumped.

Overclocking
Stable at 3.4GHZ
vcore1.43 - might be like 1.4375 or something.
ram 2.11 - im using OCZ 800MHZ Ram - stock is 2.1Volts
ht 1.4
nb1.4
sb 1.52

Bios Settings
Everything Unsynced - 1510 FSB, 850MHZ Ram
Ram Timings - 4-4-4-12-2T (4-4-4-15-2T Stock)
CPU Configuration - Everything disabled, 9X Mutliplier

Under Hardware Monitor make sure you have all Q-Fan Settings on Disabled. Theres a lil fan that comes with your motherboard - DO NOT HOOK IT UP.

Installation:
Make sure you have The Latest Bios - 0402
Im running windows XP X64Bit, Installed Service Pack 2 X64, AntiWPA - , Latest 8.43 Nvidia Motherboard Software, Did not install anything off the original cd, - Did not install Media shield and did not install Nvidia Forceware Network Manager. Installed latest Beta Geforce X64 edition software - 174.74. Heres my rundown of microsoft .net framework as well as Microsoft Visual C++.
Microsoft .NET Framework 1.1 Hotfix (KB928366)
Microsoft .NET Framework 2.0 Service Pack 1
Microsoft .NET Framework 3.0 Service Pack 1
Microsoft Visual C++ 2005 Redistributable
Microsoft Visual C++ 2005 Redistributable (X64)

Also have all latest updates from Microsoft.

Nailed 15,756 3dMark06 Points with a Single EVGA 8800GTS 512MB G92 Overclocked to 776,1942,1077.

Hope this helps you guys out, This took me a longgg time.

Put your VCore at 1.45, sorry about that.

The NB, HT, And SB Voltage settings are wrong.. Those Work but I have noticed problems. I have recently tried NB at 1.24, HT at 1.44, and SB at 1.5 I was runnen at 3ghz and finished 3dmark06 perfectly.. Give me some time to mess around with this.

Still messen with it.. If someone wants to jump in and help thats cool lol.

K anything I wrote before just say screw it.. I dont really feel like editing it lol.

cpu - 1.38
dram - 2.1
HT - 1.5
NB - 1.3
SB - 1.5
1422 FSB
800 Ram
Unlinked

15,146 3dmark06 points - Stable - Only 3.2 Ghz
Gimme more time ill figure out the higher ghz settings.

scratch the last one

CPU - 1.4
Dram - 2.1
HT - 1.4
NB - 1.4
SB - 1.5
1422FSB
850 Ram
Unlinked.

This board is very tricky and whenever you overclock it, even if its right sometimes it still messes up.. This is till a rough estimate so.. If it doesnt work, it probley wont.

Finished 3dmark06 with 15,167, hope that it remains stable.

VID!?

hey lupiron, here's some info on how my q6600 is running

cpu ->1.5v in bios, vcore ~1.46, and 1.424v under load
FSB 1600 (9x400)
38-42@idle, 57-61 encoding dvd, peak@70 under full load.

using generic super talent ram, but it's running ok 1:1 4-4-4-12 @2.0v
mobo is p35 ds3l

clownbaby what is your ht, nb, and sb voltages at?

"Under Hardware Monitor make sure you have all Q-Fan Settings on Disabled. Theres a lil fan that comes with your motherboard - DO NOT HOOK IT UP".

Whats the reason for taken fan? will it not build up more heat?

he say to not put my little chipset fan on my p5n-d?? why

You'll be fine using the QFan control in the BIOS. I am using it and it auto adjusts your CPU fan base on detect CPU temps.

Only reason I think they say not to use the NB fan is probably if you have stock Intel HSF. Because Intel HSF blows air downwards, along with the NB fan, then both will interfere with each others air flow. But, I'm just guessing here, so don't take this as gospel.

I have a tower style HSF(TR Ultima90) and have been using the NB fan since day 1.
