Can I fix a "dead" card?

post #1 of 16
Thread Starter 
I have a Galaxy GTX 460 768MB OC and I'm not sure what the problem is but all I know is that there is no display.

Is there any way to try and fix it?

If it is to old to rma then your only choice is to bake the card (I know it sounds crazy but it really works).

1. Remove Heatsink

2. Remove Thermal compound

3. Preheat oven 285 degrees

4. Place the video card in the oven with the GPU facing down on top of four balls of aluminum wrap (to keep the card elevated)

5. Bake for 10mins

6. Take it out and let it cool off for 1 hour

I'm only 90% sure on those steps, so you might want to wait until someone with more knowledge say's its ok

also make sure to wrap any plastic parts on the pcb with aluminum wrap to protect them from the heat.

No, do NOT preheat, the sudden increase in heat may crack the PCB, so have the card in the oven while you are "pre-heating" you it will not increase suddenly and risk cracking the PCB.

Edit: also have the card facing UP otherwise the de-soldering may have various components fall off the PCB if you have it faced down.

285 WHAT? it's gonna take hell of lot more than 285F i can tell you much i do reflows in excess of 220C, which is the best to repair a card because the flux will aid the solder in stick to the pads and rejoing if there are any cracks.

also BGA failure may not even be the problem some times the VRMs fail, http://www.overclock.net/t/1259614/nv-gts250-replacment-vrms-success

Like I said, I was going off of memory of what I read years ago, that's why I said wait until someone more knowledgeable comes along

i baked my dead gtx 470 a couple of weeks ago. baked mine at 240 degrees CELCIUS (yep I'm an idiot. the black stickers melted and fell off) for about 5-6 minutes ( I didn't preheat though). been working like a champ since then. I literally tried to kill it by running msi kombustor overnight while overlcocked, heaven benchmark for 3 hours etc. so far it's still working great

how are you supposed to re install drivers when you get no display? read the post carefully.

I suppose reseating, trying a different pcie slot, trying a different output, checking the PSU, using onboard graphics to check whether the bios is recognizing the card etc are all out of the question too

stick it in the oven bro laughingsmiley.gif
