View Full Version : My 6600GT exploded...

09-30-05, 03:45 PM
So I was playing a rousing game of Bridge-IT (http://www.chroniclogic.com) on Wednesday on my 6600GT when all of a sudden the machine turned off. I pushed the power button and smelled smoke. Having just swapped out my CPU to a dual-core Athlon 4200+, I thought I had fried the chip. No such luck (I still have the old CPU as a spare). Instead, I touched the back of the vid card -- youch! When I looked at the front of the card (see pictures linked below), it looks like some sort of power regulation chip quite literally blew up.

Anyways, here's a pic from my power strip's log.


Circled is the time the PC died. You can see the serious spike as the card ate it. The orange line is real power in Watts and the brownish-maroon is apparent power in Volt-Amps (basically Watts without the power-factor correction). I should note that this power strip is running my desktop, LCD screen and a set of Z-680s, as well as some other smaller things (cell phone chargers, etc...). The monitor takes ~35W and the speakers take another 40, so the pc was probably drawing ~300-350W when it died and (you can't see it in this graph, it's too long term) about 200W immediately before.

Pics of the card are available at my website (www.thirdnut.com/gallery/v/VidCard) (http://www.thirdnut.com/gallery/v/VidCard)

It's on its way to MSI for some warranty work, but I thought you guys might like to see it. :)

Oh, as you can see, the power numbers went back up... I replaced the card temporarily with a Radeon X300SE... cheapest PCI-E card they had at Circuit City and everything else seems to be working. It's a beast... ugh.

That's madness, I hope none of your other hardware has been hit....

What could make a card do such a thing?

09-30-05, 04:32 PM
Whoa, crazy, my 9600XT died to something similar to that. I changed the PSU and the card started smoking like crazy. So I got a new 6600gt

That's what happens when a video card manufacturer uses an ATI-style red PCB, especially with an NV product:)

09-30-05, 05:59 PM
None of the other hardware seems to have gotten hurt, thank goodness. You're right about the red card tho acrh.

I should mention that this card came directly from MSI, was put into an SLI rig (they gave us 2) and then taken from Austin, TX to NYC to Lincoln, NE in a static bag in a suitcase. I never really tested the card in 3d until Weds. Oh well.

You're not alone. :eek:


Woops, there goes my 5200. :confused:

I'm really amazed by the amount of power sucked by my 6600GT

It is supposed to be a "cool" chip, this graph shows otherwise http://www.anandtech.com/video/showdoc.aspx?i=2540&p=10. My Galaxy 6600GT came with a massive and heavvy custom copper cooler but still it reaches 70+ deg under load

With cards like these, it's mandatory to use high quality discrete parts. More than capacitors (which besides leaks, are not that prone to failures as many people believe) it's important that the switching regulators are up to the task and of good quality. I've seen a few cards RAMed with the power supply section burned. And even those where the capacitor were the culprits, you can bet it was an over voltage shot to cause them to burst.

another 6600gt frying, omg thats like the 100th time vie heard this in a few months, lol. hey i had a 5200 before, stayed pretty cool for me! heh i was goin for the gt, but bought the regular 6600 instead :) mine is a greenish color by PNY

Damn tacos! What the hell happened?

10-01-05, 06:33 PM
My jug of water fell into my PC case..:( And then I smashed it a bunch cause it was fun.

10-01-05, 07:49 PM

Good God...

10-01-05, 08:12 PM
What PSU have you got?

10-01-05, 08:53 PM
You're not alone. :eek:


Woops, there goes my 5200. :confused:

Wait...WHAT? That right there has to be fire damage from another source. There's no way a card could just burn up like that. It looks like somebody just held it over an open flame.

Man, I have heard about this many times already.

Somebody at NVIDIA probably made a mistake when designing the reference board. :p

I beleve many users had the inductor at the top of the 6600GT PCB blown up. It does seem to affect all the brands too. Probably not because manufecteurers using crappy surface mounted components in this case. I dunno.

Luckily XFX just launched their lifetime warantee. So if anything happens, I'd RAM it.

Only thing is... the rest of the components may be affected too. Not cool. The stuff in there are so expensive.

Thats bad.
I hope they aren't troubling you with the RMA. they can claim it as physical damage.

I sold an MSI 6600gt to a guy over at Anandtech forums. It burnt up three days after he installed it. I switched to my current 6800 card. The 6600gt cards SEEM to have a high failure rate.

Similar issues experienced by XFX 6600GT PCIe users.

I sent it out on Thursday Fedex 3day, so it should be there tomorrow or Tuesday. I really doubt this was from the handling. It was in a static bag and padded pretty well when I took it with me.

I'll let you guys know what happens.
