Distorted GPU Still Good for Physx? - Page 2

If something is wrong with the actual GPU to the point where it's producing visible artifacts, it's quite likely to produce some massive errors (and problems) when calculating physics operations.

That said, if what's causing the video distortion is further down the line from any computational errors on the part of the GPU, it may work. I wouldn't bet on it though.

PhysX will not render graphics, it a the step lower in the pipeline. The complex motion of objects, elementary particles, fluids etc is based on a complex set of variables like gravity, density, wind and so on; general relativity.
Yes you are correct, sorry if my use of terms was not correct. However this was what I meant. It is taken from here:

Go Bucks indeed! Almost done with finals week...

Anyway, I am waiting to hear back from someone else as well on another (known working) card. I will shoot the seller of the broken card an email and see what else I can find out about the distortion problems.

I will update this thread when I make a move on either card.

I have heard of baking, but can you give me the quick and dirty how-to? I can find details later if need be...

EDIT: just posted this as a guide in the graphics card section!


Yep.

Take apart the card, remove heatsink, all thermal paste (get that sucker CLEAN!)



Once down to the bare card, put on a cooking pan, on foil. and try to lift the card with 4 foil balls on the corners so its a bit off the sheet, GPU down!





Preheat oven to 385-400. I usually do 385 first and if it doesnt work, I will try 400. Make sure your ovens thermometer is accurate. Let it fully pre heat, set a timer for 10 mins, and bake your card for 10 mins.

Take card out of oven, and let it cool off for 15-30 mins. I try to let it sit as long as possible.



Reassemble card, be mindful to cover all spots necessary with thermal paste and thermal pads.



Install into computer



Profit!

Sweet. Are those thermal pads on the RAM chips reusable?

They are to a point, however, If yours are like mine were, and covered with dust and falling apart, Frozencpu.com has new ones for fairly cheap!

I'd say if this was a friend you were buying from that you knew would take it back if you can't get it working, that'd be one thing. Buying a known broken card off the web ... unless it's like so cheap you wouldn't care if you dropped that amount of money out onto the street ... I probably wouldn't, myself.

Well I would be upset dropping an amount of money on the street more than a dollar... But, this amount is reasonable to drop for a weekend project I think.
