Dragon Age: Origins
say you have a card with 1gb of video memory...
say every other game only access the first 512mb (quite common)
and then da origins accesses 756mb....and that last byte is broken...guess what happens , every time it accesses that byte....bam....crash
same scenario would work with regular ram or cpu cache
now for why its happening now....beta drivers....memory starts to overheat...but not in a catastrophic way....but it cooks a few bits or bytes....or maybe a gpu or cpu got cooked a little....only the cooked pieces fail...and if only one thing uses those pieces *shrug*
Now, the latest offical drivers have fixed the tree foliage glitches and sorted out the CTDs when I cast Ice Weapon. Maybe, as you say, somewhere along the line the components in my graphics card have been damaged and some random things in-game are causing the crashes. I'll keep testing DAO to see if it crashes again. You never know, this latest crash might have been random.
Do you know of any memory testing software that can check the RAM on graphics cards?
Regarding the possibility that there was faulty RAM on my graphics card, I found out that XFX have been known to use RAM that isn't always reliable. This was in the past though, so they might have improved it seince then.
I spent about a week talking to XFX tech support and we eventually agreed there was a hardware problem with the graphics card.
I have mailed it back to the place I bought it from to get it replaced under warranty. They have to send it to XFX so it can be diagnosed for problems. It is only after this that they will decide whether it needs replacing. I haven't even been told if I'm going to get the same model back, because it is a special factory overclocked version that isn't sold anywhere now.
Note to self: Don't bother buying XFX cards any more. I think that when the Nvidia GTX 380 Directx 11 cards are released, I'll be getting an Asus 'Republic of Gamers' version to match my motherboard.
tigerdirect might still sell the card (tigerdirect is the online version of compUSA)
Yes, my graphics card is still under warranty so I'll just wait and see what they send me. The annoying thing is that I probably won't have a new graphics card until after Christmas
