Paranoid's probably a good approche with luck like this![]()
You really have tried everything, very odd problem
I'm not sure what if any differences there might be between nvidia cards and ati that might cause the mainboard to be ok with ati but not nvidia so it does seem as though there may very well be a fault with the nvidia card especially if it does the same in a differen board.
As for getting results with successful return/replacment under warranty comunication is key so that either you can help them replicate a fault or they can help you get it working properly so avoid getting all red in the face despite how annoyed you are. What details do you know about how they tested it? The more information you have the better chance there is of understanding what's going on with this strange fault.
Best of luck![]()
Well they sent an email today saying that they will fully refund me for the card "without testing it" but wont refund the testing fee because they tested it to the manufacturers standards whatever that means and they didnt find a fault. So i've opened a new customer support thread (think this is like my 5th) regarding it and asked them kindly to supply details of what tests they run and if they even bother to try any games on it when they get it back for testing.
I explained that it isnt detected by the motherboard unless the BCLK is at 103mhz and even then it still wont run a game more than 15-30 seconds without failing. I also explained that the card seems to be able to run thing like furmark/kombustor with no problem for up to 30-45 minutes(sometimes will only last 10-15 though) doesnt go over 80c but games just dont work.I reckon this might be why they said its working because it can sometimes run these things for a decent length of time and probobly didnt run games like crysis 2/BF3 on it to replicate the fault i have?
It isnt a windows or driver issue as i've done all that and the card didnt act this way when i first got it so obviously somethings changed......and the only thing that i can possably see changing is the graphics card since virtual every other component has been replaced. CPU and ram pass all the stress tests so thats not an issue either......unless it was the CPU's PCIe express controller thats borked but i just dont see that being the case tbh.
im going to try and get it working again for ****'s and giggles since i cant get playing any games and im bored out of my skull,maybe the god of computers will have mercy on me and fix all errors and give me a break for once lol. Not gonna happen

I need a new webcam anyway so i might get one and make a video just to show exactly whats happening and post it up here if my phone doesnt have enough memory to make a video long enough(i doubt it has).
This time i will be testing the card in another machine before i RMA it aswell so i can see with my own eyes this card working in another PC.(gonna cost me 15 quid in taxi fares to do that though)

do the ATi cards work at full x16 2.0 mode?
