post #11021 of 38704
i believe nvidia and amd use different aproaches to xfire/sli. I know amd uses afr (alternate frame rendering) which allows for better scaleing but has a tendencey to be quite i.consistant interms of frame rate. I forget what nvidia uses but it allows for worse scaling but better fps consistency

They both actually use different techniques for different games.

Now I'm getting radom BSODs when I open something that uses GPU aceleration. With my old HD4850 everything runs fine, gonna send it to warranty tomorrow.

It does sound like something's wrong with the card.

sapphire-7950-pcb2.jpg

This red circled capacitor/resistor(i cant tell) is missing on my card. Can anyone measure its resistance or uF? I have sapphire radeon 7950 single fan. But i dont think that matters since they are all refernce pcbs.

I would be mega gratefull and hoping i can get that from an old card and solder it on.

Please guys:)

I had the exact same issue on a 6970. Had to send it for replacement.

Ah, anything that uses the GPU causes it? I had it where it would give me gray screens of death when I did anything GPU related. Had to return it since the other card I had (same model) didn't do it.

Question:

Anyone got hybrid PhysX working with a CrossFire setup? I was just wondering, is it worth the money? I can easily get a used GTX560 Ti for cheap now and use it as a dedicated PhysX card, even a 570 is going quite cheap used. Would PCIe X4 bottleneck the framerate with PhysX?

EDIT : Sorry, found the answer on YouTube.

Damn. I'm at work and YouTube is blocked. I searched the video out on my Android Tablet. I'll edit and put in the link when I get back home a bit later.
