Really bad graphics performance with 8800gts.

Ok, I'm getting dreadful pgraphics performance, for instance in 3d mark 06, I'm getting 7 fps in the first level where I'd normally be getting around 70 to 80 fps. Also, on boot up, a window appears saying my vidcard is getting "insufficient power and will be restricted performance wise". Also, both rivatuner and Xperttool will not allow any overclocking whatsoever.
I have just installed a gigabyte P35-DS4 and Q6600, lapped the heatsink and temps are good, and orthos runs fine for about an hour, so I'm assuming that the prob is either power related, or I've missed or screwed summat up. I've reinstalled chipset, video and nvidia drivers, tried other connections to the vidcard and generally faffed around with the pc trying to see anything obvious but no joy. The psu is an enermax noisetaker 485w jobbie and has been running the system in me sig for a long while now (I haven't updated it yet), so I doubt that all of a sudden thats decided to pack up.
Can anyone help me out here?:)

That's the problem, if the PCI-e 6-pin connector isn't (properly) in on the card, it isn't getting enough power to run at full speed, so it throttles to stop itself from being damaged. That's why you're getting low FPS like in 3d06. So it's either defo a bad connection somewhere or the PSU is dying.

If the 6pin power connector is not in properly you wont get any screen on, you'll hear a high pitched scream come from the graphics card.

*shrug*, I've experienced the "insufficient power" warnings in Windows when the molex wasn't in, but it was AGP, thought PCI-e was the same.

Dont know, I know if its not in properly on the 8800 series you just get a loud scream.
 
Okies, heres an update. I've tried the 512mb GTS in me son's pc (e6300 @ 3ghz, 2gb geil, GA-965 DS3, 430w tagan and it works a treat! Tried me sons GTS 320mb in the new mobo (p35-DS4) and it works fine! Tried 3 different power supplies, 3 cpus (e6300, e6600, q6600, in various combinations (took about 4 hours) and my conclusion is that the P35 mobo just does not like the Gainward GTS!
It could be a bios version, load being applied to the psu, act of god, I just dunno, but I took the P35 out of the equation and I'm running me q6600 @ 3.2ghz, 512mb GTS, enermax 480w noisetaker, 4gb geil memory all working fine.
As soon as I put the 512mb GTS and P35 mobo together, it a no go at all, I get the message about insufficient power.
Any ideas on this?

You checked the bios for PCI-E voltage and all that?
 
I tried variuos combinations last night and the only the P35/gainward GTS combo fails to work like I said. I can't fathom why an 8800 gts 320mb and an1800xt work fine and not the 8800gts 512:confused:
I'll admit I didn't try raising the pci-e voltage (I can't remember if there is an option to do that) or locking the pci-e bus at over 100 (I suppose I shoulda tried higher than 100mhz locked.
I might have another play today ( was very early in the morning when I gave up on it) and try messing with the pci-e frequency and voltages.:)

One interesting thing I just noticed is that when scrolling up and down these pages last night, the text was "blurring" when it moved when using the P35/8800gts 512mb. while using any other combo, the text is fine and doesn't blur. Just thought I'd mention that.

Try taking all USB devices out, I wonder if its a problem with the USB power doing it then, I know when I plug my dads sat nav into the USB to charge the whole system goes laggy, I dunno about games tho but its awfull untill I unplug the satnav.
 
Can't say if this is your issue but, I remember reading somewhere that there is a timing loop in the graphics card that if within that loop it does not recognise that enough power is ready that this happens. I think it was the PSU behaviour that caused this issue. If you google around you can find some more details.
