Defective 7800gs agp card?

Just received and installed an eVGA 7800 GS-CO AGP card from newegg and am
having problems.



I deleted all the ATI driver files before doing the hardware install. After
putting in the new card, was able to get into Windows XP ok and and install
the latest drivers from Nvidia without a problem. I then tried to run an
older game - Civ3 and the system shut down completely. Tried restarting
several times but the system kept shutting off before the monitor would
display anything.

I then tried unplugging everythig and reseating the card and the system did
start to come up. A message was displayed saying the overclock had failed
and asking whether or not I wanted to reset the bios settings to default.
Guess I should have said yes, but I selected no and the system immediately
shut down.

At that point I took the card out and re-installed the old ati radeon card
without problems. I did notice what I thought was a burnt smell when
removing the old card.



This is the first time I've ever had problems like this installing a new
card or piece of hardware. Guess I've just been lucky in the past.
Anyways, does this seem to you guys that the card is defective? Should I
just return it to newegg for a replacement or is there something else I
should try?



Am running this off an asus p4c800-e deluxe motherboard with a P4 3.2
processor and 1 gig ram. The power supply is an antec rated at 480 watts.
I did a complete renistall of everything a few months ago and all has been
well with the system. And as I said, all seems to be working well with the
old card.



Thanks for any help on this.

Try restarting the computer by holding down the delete key. Then go into the
bios settings and be sure they apply to the new video card. Such as AGP 256
etc.. Then try it again..

Thanks for the tip. I did adjust the agp aperture size from 64 to 128.
Have had no problems yet.

Have to say I'm a little surprised that did the trick. I assumed that a 64
size would be fine on a 256mb card. When I put my last system together a
couple of years ago I was told that the aperture size should be 1/4 the
card's memory size.

Anyways, thanks much. This card is much quieter than the radeon I had in.

The aperture can be almost anything, as it has almost no effect on
performance at all with today's video cards.

I'm almost willing to bet that it was a coincidence that it worked after you
changed it, but I've seen some weird stuff when setting that. My system
slows down unbelievably if I set the aperture to 4MB. Any other value, it
runs fine.

On some systems, setting AGP aperture lower than 16 or 32MB will
disable AGP transfers altogether (transfers will run at PCI/33MHz or
even ISA/8.33MHz speed). This accounts for your slowdown.

Yes, I think you are correct. Could be that some other setting in the bios
was unintentionally changed by me which resulted in the correction of the
card's behavior. Or perhaps it was physically connected better the second
time around. It's been a couple of years since I put the computer together
and haven't done much modification of it till now, so am a little rusty at
this sort of thing. Most likely some misstep on my part.
Am still thankful for the poster's original suggestion because it did result
in a correctly working system.

When I first got my card. I tried 128 to see if there was any difference.
And for some reason it messed up more often. Set it up to 256 and it flies.
While at it you might go over to NVIDIA and download the latest BETA driver
84.43 It made a big difference in all of my Futuremark scores ! And the card
is actually running 2 degrees c...... cooler !
