Overclocking my 8800! :(

Well, I recently built a new system, ordered the parts from the wonderful newegg.
I am running:
Asus P5N32-E SLI Plus Mobo (nforce 650i)
Intel Core 2 Duo 6600 oc'd to 3.0ghz
EVGA 8800 GTX
2 WD Raptor's - Raid 0
4 gigs of Kingston DDR2 (1gig sticks)
and finally a couple of lite-on optical sata drives

Here is the problem, I am an overclocking fiend, and I always love stressing my parts to squeeze out as much performance as possible out of my system.

I have had great success with past video cards and processors, my 6600 is running smooth and stable at 3ghz.

However the problem lies with my 8800gtx from EVGA. I am wanting to overclock this baby in Windows Vista x64, I have read many posts with people having no problem, especially with the latest version of Rivatuner. However, whenever I use that program, and OC a modest 15-30mhz on the core/mem. about 30 min or so of play in battlefield 2, battlefield 2142, or even counter-strike causes a display driver failure and I get that damn error. "Display Driver has failed and Has recovered" message pops up and my game completely screws up, causing me to restart to get things back on track. Another thing is from what Rivatuner was telling me, my gpu temp never got above 74 degrees C, Ive heard of many many people with 8800s running there cards in the mid-high 80s. I am definitely ruling out an overheat issue, simply because im hardly overclocking at all and its unstable, where as when I dont overclock its perfectly stable.

I have also tried ATI tool .27 beta1, works ok but....no fan control.

The thing is, if I have absolutely no overclocking utilities up I can play for as long as I want, whatever I want completely stable with no display driver failure. I have tried several different nvidia drivers, 158.18 (which is the latest nonbeta) and the beta versions 158.25, 158.43, and the latest beta version 160.03. Switching to any of these drivers makes no difference at all with the problem at hand.

I have tried Ntune, its a piece of crap....It allows absolutely no fan control and NVmonitor simply refuses to open no matter how many reinstalls of Ntune I do...It just opens and then does not respond and windows tells me to close the damn thing. So with Ntune, I am not able to control the fan, nor can I view gpu temps.

Does anyone have any other piece of software or insight that would allow me to overclock, control fan speeds, and view gpu temps at the same time without a failure of the display driver??

Sorry for the long post, any information whatsoever would be helpful, thanks all. :)
 
Have you tried increasing your PCI-E frequency up to 105MHz? or perhaps give it a bit more voltage?
 
No I havent tried that, Im 100% sure its a software/driver issue tho.

Thx for the feedback

any other suggestions guys?
 
I said this because when I overclock my CPU my PCI-E becomes 1x instead of 16x unless I raise the PCI-E frequency above the default 100Mhz...

I assume you bought a good PSU...you need steady amps with that card...
 
hmm ill go give it a shot then, so 105mhz you say?

upping the voltage to what exactly in the bios?
 
yeah 102 or 105, you can check with cpu-z if its running at 16x

add just a bit more voltage, like 0.1, again a good PSU is important, alot of game crashes occur due to poor PSUs
