Overclocking Help..Memory/CPU/GPU problem, possible [H] stumper

[Dethman]

Ok, Im a intermediate overclocker, and ive ran into a weird problem here

specs

Asus P5B Deluxe
E6550 @ 3.2
2 x 1gig G.Skill HZ PC6700
Evga 8800gts

My comp was OCed to 3.2ghz..i think it was 465fsb

I had the main settings in my bios set
Ram was set to 5-5-5-15
Ram Voltage was set to auto
CPU voltage was 1.35

Northbrigde and south bridge were bumped up a little, dont remember exactly

The problem started when I would boot up my computer...and then games would run really slow...like COD4 would stay under 20fps...and then i would restart my computer and everything would be fine...80fps

All of a sudden the problem wouldnt go away...no matter what i did...i was lagging like crazy in all games, that I used to beable to play...(made no hardware changes)


First thing i tried was reinstalled the videocard drivers...didnt help..then i downloaded Gpu-z..and this is what i found

see that x1?...

So i set my bios to default settings..and then my computer just BSOD'd and restarted it self..

I thought to first check the ram, I pull out one stick..and it works fine....I put the other stick, and it doesnt post

So I think..well i had bad ram...so i put the 1 gig back in boot up...works fine..I check gpuz and it says @16x

Then i restart to go do a mild overclock while i wait for the stick to get back from RMA

I set the fsb to 450..
cpu Voltage to 1.35

and set the ram from auto SPD to 5-5-5-15 again like i had
lock pci-e frequencie to 100
and pci to 33.33

leave everything else at auto...

I boot up, and im back to the @1x problem again, cod4 lagging like crazy


Anyone know what Bios setting is throttling that?

ok well i think i figured it out

i set the southbridge to 1.55 and the north to 1.45

and reset my fsb to 465, and seems that the Video card is running back at 16X

im going to reboot a few times, and load up some games, and see if its stable

ill keep this up incase anyone else ever has this problem they can try this resolution
