graphics card settings

  simonsup 19:06 04 Mar 2007

hi just upgraded from an geforce 6 6600 agp to a geforce 7 7800gs overclock.
Im pleased with it apart from a few lock ups in games and the odd blue screen of death.
what should my bios settings be?
they are agp set at 1gig.
fast writes disabled.
i am using v91.47 drivers from the install cd.
the latest drivers v93.41 crash my pc all the time.
not sure what the problem is, any help would be gratefull.
My system:
abit kv80 mobo with via m800 chipset.
2 gig of ddr400 ram
250 gig pata harddrive.
geforce 7 7800gs graphics card.
creative 24bit live extenal usb sound card.
dvd burner.

I do not know what you mean by agp set at 1 gig. If you mean agp aperture it is normally 64. Lock ups are sometimes caused by lack of power, ether not enough or a cheap psu.

as citadel has stated, the cause of the lock-ups may be an underpowered psu.

I believe the 7800GS uses an extra cable from the psu, and with 2 Gb of ram I would suggest a minimum of a 450watt psu, and better with a 550.

hi peeps i am using a blue storm 500 watt psu and yes i have plugged in the extra power lead at the back of the graphics card, is 500 watts not enough?
i play mainly tiger woods pga tour 07 but is very jerky and crashes alot, i got the latest mobo chipset drivers installed from via. everything else seems fine just this game, direct x is ok aswell.

if i took out i stick of ram and took out one of the case fans (I have 3 case fans)would that reduce the load on the psu? and make things a little better?

There is no substitute for genuine watts from a quality PSU.

Re the AGP setting. This should be either 64 or 128MB - any other settings are unnecessary.

This will help you to understand the reasons:
