Dead 9800GTX+, need advice - Page 2

post #11 of 30
Thread Starter 
I bought a kit at newegg for $10 lmao
It's lemon juice and a cleaning stuff.
It's works perfectly though

I just remembered, when I first opened that card, there was some thermal paste that dripped from the GPU and it was covering some pins around the GPU.
EDIT :

As you can see, there are pins around the space where you usualy apply paste.
Does it matter if it spread to the pins ?

EDIT 2 : As you can see, on this picture it the thermal paste did touch the pins since there is some residue.
Mine has the same can it be a problem ?

EDIT 3 : I will simply rub all those pins with a Qtip with some lemon juice, it just can't be a conductive TIM that nvidia applied first !

I've baked several cards (and a motherboard) back to life. I usually heat the oven to 360 F and put the card in for eight minutes.

However, on baked cards I generally alter the BIOS after I've repaired them so that the fans run at 85 to 100 percent and I also under-clock them to stock specifications (or less) just to insure they NEVER overheat again, so there will be NO MORE micro-fractures due to temperature fluctuation.

None of the cards that I have baked ever stopped working because I addressed the problem that caused the micro-fractures in the first place. Temperature fluctuation causes the PCB to expand and contract, which causes micro-fractures. If a card goes from room temperature when off, to 50 C on idle, to 90 C when running this may not damage the GPU, but it can easily damage the rest of the card as the expansion and contraction of the materials can warp the card.

To eliminate extreme temperature fluctuation I have done the following on repaired cards:
  1. turn the fan up to 100 percent via software or bios;
  2. under-clock the GPU to stock settings if it is an OC model; and
  3. improve air flow in case the the card is installed in.

A loud video card running slightly slower than it used to is FAR better than a dead video card or a video card that dies within a few months of use.

some of it you just might not be able to get off the GPU. If it comes to that it really wont matter. Just as long as you get atleast 98% of it off you are good to go!

I will indeed crank the fan to 100% (With my computer being in an other room, all my fans on my rig are at 100%)

I will probably try to downclock her if heat is still a problem.

As for the CPU TIM, I will clean it the best I can tonight.


On an other note, I've seen people baking cards because of artifacts, but mine just don't post.
Is baking still an option ?

It should be fine. Generally problems on computer parts are just something coming unsoldered. So i would say after all the troubleshooting and that doesnt fix it that baking is the next step to attempting to fix it!

Either it will work or it won't. As long as you have tested the card in multiple systems, you have nothing to lose. Just be prepared to unplug the system if you smell anything funny when booting it.

However, MAKE SURE THE card's teeth are clean before you consider baking it. Gunk on the teeth of the card that fit in the PCI express slot can be a false positive.

Another false positive is dead capacitors. Older cards did not always have solid polymer caps and often bulged or had electrolytic fluid coming out of the tips.

That's great !
Thanks a lot !
I will come back if it worked or not

+rep for everyone

What temps ? 290F for 10 minutes
GPU up or down ? facing up
If something melts, wouldn't be better to be facing up ? facing up
I know I need a pan and 2-3 bits of alu as feets so the card doesn't touch the pan. yes make 6 3 on each side of the card so the PCB doesnt flex
Do I need to remove the DVI ports ? (IE the whole connector thinggy ???) no

Ty for you reply, I will try to remove my GTX 560Ti and put that 9800GTX as main instead of second.

I also use tinfoil balls to hold the card above the metal tray.
