The reason I recommend trying to underclock the memory is because electronics have a tendancy to breakdown over time, underclocking the memory will reduce heat and could possibly increase stability enough to render the card usable once again. Think of the card as if it already has an overclock, if you started receiving artifacts your first response would be to start reducing the clocks, add more voltage, or increase cooling until you stop seeing artifacts.
Just to make sure this is a last ditch effort. Have you tried driver sweeper and a fresh install of your video drivers? Have you tried manually setting your fan to a higher duty cycle (ie:100%) and then tried stressing the card? If you've done both then read the next section.
I assume it's no different for your card or mine, except the clocks of course. Start by downloading MSI Afterburner
. After you've installed it go ahead and open it up. You should see core voltage, core clock, shader clock, memory clock, and fan speed. Your memory speed should currently read 999. I'd start by reducing it to 900 then stressing the memory like you were before. Just drag the slider until the memory clock reads 900MHz and then click apply at the bottem. If it still artifacts you can continue reducing it in 25MHz increments and stressing it. Other than that I don't know what else to recommend. If you decide you want to try it you could always replace the thermal pads and paste. It's not that hard, but you should be as careful as possible.Edited by C.Jackson - 1/13/11 at 10:39pm
