Re: 6600gt graphics problems (white lines / slow)
 

The 6800GT is a gutsy card for stealing power from the PSU.....I had a 500w power supply and had to change it the other week to a new 600w one as my comp kept rebooting. Its worked fine since. I'd check your PSU and do a fresh install.

Re: 6600gt graphics problems (white lines / slow)
 

thanks for the reponses guys. some games work pretty much flawlessly. my PSU currently is 400w (plus this is a 6600gt not 6800gt). maybe ill try a more powerful PSU then
quick q, as i said when i go into the BIOS, scrolling about makes the screen flick slightly and selecting things seem slightly slow. my ATI card was flawless in this area. Any ideas?

once again, thanks

Re: 6600gt graphics problems (white lines / slow)
 

Sry i wrote 6800GT in my last post by mistake....i was referring to the 6600GT though as i have one myself. I was having problems with my 500w PSU when i installed this card, elbeit not the same probs as yourself but im willing to bet its your PSU. As my last post stated change the PSU and format the comp.

Re: 6600gt graphics problems (white lines / slow)
 

OK i tried a new HD with just comlpete install of windows + GPU + drivers and still got the lines on the games i was having problems with
So thinking of getting a PSU.
Seen these ones on ebay, but from the reviews people are saying they are not really 600w? Can anyone shed some light

thanks people, getting there slowly...

this one seems the same but no reviews so anything about it not reaching 600w...

No and No

something like this is what you should be lookin at http://www.ebuyer.com/customer/produ...duct_uid=35884

Re: 6600gt graphics problems (white lines / slow)
 

ok then...what do i need then?

Re: 6600gt graphics problems (white lines / slow)
 

sorry link added

Have you tried the card in another machine?

Re: 6600gt graphics problems (white lines / slow)
 

sounds to me like a case of video card over heating and artifacts.
some of the older 6*** nvidia cards get really hot an if theres already heat build up in the pc then your gonna have video probs.
Also some of the lower price bracket cards have cheap n nasty fans on them that dont quite do the job there suppose too.
As for power, i ran a 2600xp @ 2.2ghz, 2 hdds, 1 dvd writer, 1 tv card, a nf7ver2.0 and leadtek 6800gt all on a bog standard 350watt psu with out any problems at all so i realy doubt this is a psu problem.
currently i run a amd64 3000, an8ultra nforce 4 mobo, a 120gig hdd, a 300gig hdd, 1 dvd writer, 1 tv card, 1 sound card and pcie 7800gtx all on a 400 watt hyper psu again no problems at all.

My moneys on heat. maybe worth you looking into better vid cooling or tryin to increase air flow within the pc itself by adding more case fans.

Re: 6600gt graphics problems (white lines / slow)
 

i felt the card to see if it was burning hot after playing some games after about half hour. it was hot but not burning hot... im gonna try it in another machine...

oh and also my case has got 3fans in it. 2 are wired up and on... so is the fan on the GPU...

6600gts are well known for overheating :erm: , and simlpy putting ur hand to the card to test is not gonna tell u anything, what ur feeling is most likely the heatsink which is sitting on the gpu which has a fan blowing onto it and keeping it cool, so its not going to be as hot as the core this however doesnt mean the gpu is getting equally cooled.
what temps does ur drivers controlls say the gpu is at?

Re: 6600gt graphics problems (white lines / slow)
 

i havent checked (im at work at the mo). how do i check the GPU temps?

Re: 6600gt graphics problems (white lines / slow)
 

My 6600GT is running on stock cooling and my AMD 64 3000+ is also running on stock cooling, with no extra case fans and all temps are well within normal range. Surely the GFX would have to be overclocked even more than what it is to get serious heat issues?

Re: 6600gt graphics problems (white lines / slow)
 

I havent overclocked anything. well not yet anyway as i dont really know how. what would explain the display in the BIOS flashing slightly and having a slight delay when scrolling through options...?

Re: 6600gt graphics problems (white lines / slow)
 

from what i understand rivatuner will tell u the temps roughly, you can get this at www.guru3d.com but some older drivers will display the temps in the driver options in the controll panel.
To give u an example my 7800 sits at 49c idle an it rises to 53c under load, i wouldnt expect a 6600gt to get any hotter than 55c.
But as ur intentin to try the card in another pc then that may be just as handy espically if there is no change in the way it acts.

Re: 6600gt graphics problems (white lines / slow)
 

It may also be that you have a faulty card.
