Strange problem when overclocking Q6600 & P5N-D

[Guest]

Hi all, I'm new to this forum but only because I can usually find most my answers here on Tom's Hardware, but in this case I have a problem I cant find an answer for

My Setup

Asus P5N-D (Nforce 750i)
Intel Core 2 Quad Pro Q6600 95W Energy Efficient 2.4GHz SLACR G0 Stepping
OCZ 4GB Kit (2x2048) NVIDIA SLI - Ready Edition DDR2 PC2 6400 800MHz Dual Channel EPP 5-4-4-15
OCZ 600GXSSLI-UK nVidia SliReady600W Power Whisper Technology Active PFC
ASUS Silent Square EVO Quiet CPU Cooler
2 x(SLI)512MB XFX 9600 GT, PCI-E 2.0 (x16), Mem 1800 MHz, GDDR3, GPU 700 MHz(OC'ed alittle)

BIOS-0701
mem : 5-4-4-15-t2
FSB : 1066
unlinked
Multi: x9
vcore: 1.42
nb: 1.48
ht: 1.48
sb: 1.50

PC is nice and cool 30C-40C max
My problem is when I overclock/change settings in BIOS all seems well, but after I F10(save&exit) I lose the settings for FSB(it reverts back to auto), the memory timmings/voltages save but just not the FSB!!!

I spent 6 hours last night trying to find a way to solve my problem but cannot find the answers I seek on the net, the closest I get is this:

http://www.tomshardware.co.uk/forum/247921-11-asus-saving-bios

but my problem if different as it happens even I i move FSB to 1060(DOWN) or 1070(UP) it always goes back to auto from manual in BIOS.

Is it my BIOS/setup/fault board I have no my ideas.

Please help wise people!!

Had the same problem after attempting to overclock my p5n-D. would not hold any settings and reverted to auto. I RMA'D the main board. Second board started to do the same thing after a couple of reboots. In my case almost any setting made would revert back to default settings. I resolved the problem by flashing my bios after getting the issue and have been able to overclock with no problems after that. I am running bios v801 now.

P.S. make sure to use the flash tool from the bios or from boot disk( I user bios flash tool ) as the windows flash tool is really flaky and I have killed a couple of main boards with it .

Hope this helps

with my p5nd i could not overclock over 3.2ghz my q9400. i raised the nb voltage and i believe that the board went to hell. i dont like that board because all i had was problems with it. yesterday i got an EVGA 750i FTW and wow i love it. 3.6 ghz 450mhz fsb no problem super stable. i would tell you to change that board with a evga 750i.

I was thinking it is possibly an incompatibility with the Q9400 but now im thinking that maybe the ram is incompatible.
