I ve got a gtx 580 without smd Crystal oscillator, anyone knows a compatible oscillator for this card? the card is from Gainward,thanks

Re: Nvidia GTX 580 crystal oscillator help!
i`ll put the card on the bench tonight. Mine its the phantom with black radiator.
make pictures and post themJust cook it! It's already broken. -

Post the pictures. Overall and close macroJust cook it! It's already broken.Comment

Re: Nvidia GTX 580 crystal oscillator help!
There are a few pictures here http://ixbtlabs.com/articles3/video/zotac-2-p1.html
Looks like a 27.000 mhz crystal
Check the internet images, you might see one like yours and be able to identify the crystalLast edited by R_J; 10-30-2017, 11:02 AM.Comment

Re: Nvidia GTX 580 crystal oscillator help!
i bought the 27mhz similar to this:

and the pcb is the same of this :

Re: Nvidia GTX 580 crystal oscillator help!
i will get the smd oscillator next week sent from england , i tried to solder a different type
http://thumbs3.ebaystatic.com/d/l225...87xJ0sPE3g.jpg
but doesn't seem to work,fan is spinning but the card works until i try to install the driver where it carshes in a black screen with coil whine noise...Comment

Re: Nvidia GTX 580 crystal oscillator help!
Can your power supply, supply enough current for this board? I know they take a lot of current via the extra 12 volt connectorsComment

^^ Can't believe you're still wasting power with that thing and have not at least reflowed it already.
A working TV? How boring!Originally posted by PeteS in CAComment

Re: Nvidia GTX 580 crystal oscillator help!
No, no wasting power - I haven't powered it on ever since I tested it a while back. I just been busy with other things, so that card's taking a back seat. I'll get to it some day, I promise.

Re: Nvidia GTX 580 crystal oscillator help!
LOL!!!
Funny comments!
I have a Graphics card that I;ve been trying to repair for a friend. if anyone has a link to a good website to diagnose them; please post it.
I'll take a look at the card and post the make and model tomorrow, if you need it.Disclaimer: Don't trust a thing I say-I am frequently wrong!!!
I have tons of spare parts, some used, some N.O.S. ham transistors and caps. Message me if you need any parts.
Some of the things I've fixed:
60" Vizio-bad LED's. iBook G4: Resoldered VCC Plug. Geo Tracker ECU: Swollen / Leaking capacitors. Windows Laptop: Soldered broken LVDS wires. Dryer: Burned contact on temp switch. Oven in R.V.: Bad contacts in relays-Exploded by the looks of them! Samsung Oven: Burned contacts on Relays. MSI Motherboard: BSOD-Swollen capacitors, bad graphics card, Moved SATA Input from SATA 1 to SATA 2 plugComment

Re: Nvidia GTX 580 crystal oscillator help!
I have a 27 MHZ Crystal sitting in my parts bin if you want me to mail it to you!?
It is a through hole mount. I can measure it with my chinese calipers. Let me know if/how you want me to test it.
Let me know, buddy.Last edited by NeedsMoreFlux; 11-03-2017, 02:12 AM.Disclaimer: Don't trust a thing I say-I am frequently wrong!!!

Re: Nvidia GTX 580 crystal oscillator help!
I figured it out!
At the end some capacitors are gone,the noise came out from broken capacitors meanwhile the chip is fine, i can even use the oscillator that i tried to solder before , it's working but i will use an smd type oscillator instead,smaller and fits betterComment

Re: Nvidia GTX 580 crystal oscillator help!
I though the noises it's made by coils.Just cook it! It's already broken.Comment

Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"
May complete this post at a later date with more details.
Basically issue is a combination of thermal dissipation of the chip with hotspot,... -

I'm troubleshooting a reel controller board for an IGT slot machine. The digital section seems to be dead. There is no USB communication, PC or utility program for flashing firmware do not see it but they do see good/working boards. I noticed the waveform on the crystal is very erratic/asymmetrical/glitchy on the bad one compared to the nice even waveform on a good board. My question is would this most likely be caused by a bad crystal or something gone bad in the circuit loading it down? I'm attaching a couple pictures of my scope probing the good and bad boads.
