Never being able to leave well enough alone, I though I would pull the RAM sinks off my newly puchased - used GF3 (oem card pulled from a dell). The oem cards use that pesky epoxy, so they don't come off easy, even after a long stint in the freezer. Alas they did pop off and I cleaned things up, slapped on some newer/bigger sinks and slid the card back in the rig.

Boot up and the post text is completely garbled, and a cold chill runs through me. I tried the card in another machine and it was still screwed, so i pulled it and threw it on the junk heap, overcome with self-loathing.

A few days later I put the card back in a junker machine, booted it and started to bend the back of the card back and forth, the garbling would get worse and better, but it was still a hosed card. Then I started pushing on individual RAM chips and finally isolated 2 chips in particular that when pushed on one end would make the screen go bananas. Conclusion - must have broken some contacts on these when I pulled the RAM-sinks. I pushed down hard on the afflicted ends of the 2 chips and rebooted and voila, a clean screen.

Oh joy! I broke out the JB Weld (SUPER epoxy) and mixed up a batch. I put a dab on the afflicted ends of the 2 chips and clamped em for 12 hours and here I am typing away on my fully functional GF3, brought back from the dead.

Moral of the story? There are too many to mention, but if you have hosed a card in a similar manner, know that you may be able to fix it.

this is an excellent insightful post, and I really thank you for it.......

but I'm trying to get a very precise handle on what you're saying here:
are we talking about soldered in ram chips that have possibly had the soldered joints cracked under bending
pressure, or that the ram metal leads themselves have cracked or disconnected from the solder???????

a lot of people are buying GF4's now that boot up with garbled screens, and I wonder if the elaborate HS now
normal issue that span GPU and ramchips are warping card similarly after epoxy curing

this is really fascinating (opens up a whole new area of investigation) to me, errr.....

you couldn't pull it out and look at the area with magnifying glass possibly? (no hurry - anytime)

Edit: And maybe PM me with result

Bozo - seriously, i feel like the whole thing is a house of cards, so i want to leave well enough alone. i am pretty sure i broke some of the solder joints tho.

HowDoesItWork - i am confused as to why you would chose a nickname like yours and then ask me that question???

I almost killed a GF 4400 by the same way. The ramsinks don't come off easily because of the pesky epoxy. And when one of them did, a large surface mount capacitor was ripped off too. Exactly the same deep thrill came through my mind, luckily I've got a solder iron at home. :)

After so much hard work, the memory does't overclock any better. How ironic.
