Hi guys

I have bought a psu from OCUK and i was wondering if it is maybe a bad choice for GTX260

I have horizontal line rippling across my screen when i enter 3D mode. Its very very annoying and sometimes after a few minutes it goes away but then comes back again worse or not as bad but always still remains on screen

19' Targa screen and i had a AOC 20' before that and it happened on both. I dread to think i have bought two bad screens, so i dont think that and am now thinking its something to do with the card drawing power form the PSU.

Its a Gainward GTX260 Golden Sample and the PSU is OCZ 780W ModXstream

I have the Asus P5B Premium Vista Edition

I have tried everything i think , i changed different refresh rate from 60 > 75 but no better or worse results. I have underclocked my card to just above 2d performance mode but once i enter a game , the lines come back.

I have reinstalled the o/s and tried all drivers from 182 > the current driver release.

I am at a loss now and i havnt a clue what to do. I do not know which part of my pc is causing this. I would really love to pinpoint where this is coming from so that i dont have to fork out 100s for a new card,psu & mobo


Any ideas ?

This is my first post i know, but am not here to just get answers, i hope i can become a part of this place as i do shop mainly with OCUK :D

The PSU is more than enough for the GTX260 also make sure that the card is not overheating as this could cause artifacts and the like.
 
Thanks for fast reply guys!

Some good info but i have tried most of that too :( I downloaded rivatuner so that i could force vsync in directx games but this does not make a difference either.

My cards fan is set to 40% default as the noise on it after that becomes abit too much hehe It peaks at 59c when playing Arma 1 but in Arma 2 it peaks at 79c , which isnt that bad either.

It happens in any game i play, once i go the card goes into 3D mode the lines appear. Its so sad really cause i have hit a sweet spot in terms of having the proper hardware for once but now being let down by this strain.

I matched my Q6600 to my default cards core clock and that did not make it any better either cos i thought maybe the GTX260 was bottlenecked by the cpu or the other way about . I have made use of the second 4pin cpu plug on this psu aswell ,although it had reduced the overall temp on my cpu which was handy, it did not fix this problem :(

I think i may upgrade to DDR3 shortly so maybe i better just go ahead and get a new mobo and get the 650W Corsair .


I read somewhere that the GTX260 needs a min of 36amp on the 12v rail and if that is true numbers then i think it could be this psu . It has only 20amp on any given rail although it does have quad rail @ 20amp each but maybe having a nice 40amp single rail would provide cleaner power to my system when it enters 3d mode.....idk


Thanks for advice guys, al try put fan speed to max now and see if that cures it.

Mate I use an OCZ ModXStream 500W PSU with my oc'ed GTX260 and I got no problem with it.Can you get hold of another PSU and test it just to be sure theres nothing wrong with the PSU?

This is good news in some way that if yours is working fine on 500W then it must not be my psu :DI was going to buy that very same one, only i got worried when i seen 600w or 650w min for teh 260, I should really stop reading those reviews :p

I have an old 500w OCZ here too, its the older model the OCZ500WSXS but that would be abit hairy running that cos it has only duel rail with 18amp on each. Do you guys think this would be ok for a test ?

Have you used a different video cable? Is there anything near that might be causing interference? Cables in fully?

The tft runs off a vga connection/lead and the card has only DVI . I have a small VGA to DVI adapter, sadly i will have to fork out for dvi tft screen to test that hehe, but that to me does sound as if it could be the problem aswell

I'd say this was almost certainly a problem with the monitor or the VGA cable. From my experience I've seen the same issues several times and it's always been a bad VGA (never DVI) cable or monitor.

:eek: i hope it is not the screen, its only a few months old. I shall buy a new vga lead, this one is very long looking ,maybe i get a shorter cable it will make this niggle go away. Cant buy a screen atm but that is worth a try with the cable first.

Thanks Alex
 
Hi all, just an update to the thread for the sake of anyone else.

I got a new male > male vga cable and it seems that the wavy lines was indeed caused by the cheap vga lead which is good news :)

But now i have another problem hehe. When i installed new lead, booted up pc and then the screen was all wrong , I had screen res upto 1920 when before all i could select was my native of 1440 x 900. 1440 wasnt on the list anymore and the drivers defaulted it to 1024 x 768.

I reinstalled the drivers and it did go 1440 for slight second but it popped back to 1024 again.

I then went in and added manually a new res of 1440 x 900 which stays on ,but once i reboot the computer, it goes back to 1024 again :(

How can i lead cause so much mess?
