Can anyone with a 9700PRO do me a favor? (updated)

UPDATE

Markings appear to be :
P25AD
FDS
6898A

And THIS is what happened to the IC... :Q

------------
Can anyone of you with a 9700Pro do me a huge HUGE HUGE favor, and that is, look on your card and tell me what exactly are the markings on that IC :

See the IC that's in the BLACK position? I want look for a new IC, but the top printing has been smeared off. >> uhoh.jpg

If any 9700Pro owner can help me with this, I'll be forever indebted to you!
 
cool I was going to same question for my 9500 pro. It has ram sinks that were attached by adhesive tape though.
 
Theoretically you should be able to gently but firmly twist (NOT pull) the heatsinks off the chips. Generally the heat sink adhesives are designed to have good tensile strength but poor shear strength. Doing it after the card is warmed up from operation may make it easier.
. Using one of those aerosol chip cooler sprays to dramatically drop the temp of the HS relative to the chip would also probably make them fall off.
.bh.
 
Woah, you guys are fast. Cheers! :beer:

Will give it a twist later..if that doesn't work, i guess in the freezer it goes :Q

JBT, did you fix your USB mem stick to bootable?
 
HOLY SH#T... I need some help guys

I just gave one of the heatsinks a twist, it came off alright.. but so did THREE of the transistors that were glued onto the heatsink!!!!! :Q:Q:Q:Q

They're fairly small... my only hope now is to re-solder them on right?
 
Transistors? What? The only transistors would be on the GPU itself.

Now Capacitiors maybe little round things? Or Power regulators which are like a black squareish piece of plastic with 3 prongs?

Voltage regulators would make sense to glue to a heatsync since they often get quite hot.

BTW are you talking memory heatsyncs or the GPU heatsync?

If it looks like that which is very likely, there are many resistors nearby the memory modules. Those are surface mounted kinda things so its very difficult to resolder them. I've done it before however. Also the fact that often those surface mount resistors when broken off no longer resist the same value that they are supposed to and could damage the card.

Click to expand...

hey man that's not a good thing...
ruh roh!
 
🙁

They're actually on the back of the card ...

if you click on that link, on the upper right you see that silver plate. there was a heatsink on tpo of that plate, and i yanked the whole thing off :brokenheart:.

Ii'm not sure if they're called transistors? But under that silver plate, there are those two black "things"... the ones I pulled off are the size of the second one underneath the plate. I guess they're not transistors... but .. resistors maybe?
 
I just pulled off one more heatsink off the square ram chip, thankfully the chip stayed on. It was stuck on using some double-sided tape...

Man, I didnt realize the silver plate came stock on the 9700... 🙁
 
Well those "Black things" are ICs which are integrated circuits, they can do anything from control logic to analog to digital converters. Likely since they apparently need extra cooling they are voltage regulators for like the memory and or GPU.

It is possible to fix something like that but you will need to find a good friend who knows how to solder REALLY well.

BTW this is a early revision of the 9700 which dosen't have that metal plate. From the looks of it the upper one is a voltage regulator, and the bottom some sort of IC (I dunno what it does).
 
D'oh... yeah they look really small and space is TIGHT between the legs... I'll have a hard time soldering it togehter. My friend told me about phone repairmen who use hot air guns to melt the solder, tis supposed to be better for smaller electronics.

At least one of those ICs have

4804
0219

written on them... dont know what they mean. Would these be available in electronics stores?
 
Sigh, yeah you're telling me 🙁
I wanted to put something in the PCI slot and that danmed heatsink was in the way...

But now it's really broke so I HAVE TO FIX IT!
 
If the part that came off was SMT then solder it back on. Use a low wattage iron with a real skinny tip. Once you know where the parts go. Glue the part you want to solder down first. Pieces should be thinned with solder before. Then just apply heat to part and solder will melt and join. Since it's already broke go for it. Don't try it in a good computer either. In case something is wrong don't want the card damaging other parts.
 
THANK YOU for those tips Viper... I searched around google looking for tips soldering small ICs, and one site mentioned glueing the part down. Is this superglue we're talking about.

 
Hot glue works for me 🙂 However, make sure the hot glue is completely dry before putting power into it. Hot glue is electrically conuctive when it is still cooling.
 
Take the ICs off the heatsink, read the numbers, order new ones, put everything in a bag and mail it to me. We have the ability to solder such things. No charge. Hey, you might get lucky...
