"The Ti4200 with AGP-8X support was based on this chip, and sold as the Ti4200-8X. A Ti4800SE replaced the Ti4400 and a Ti4800 replaced the Ti4600 respectively when the 8X AGP NV28 core was introduced on these" :p

Yeah I've read a few reviews on it and some say a 4200 and some say a 4400.

So the ti4600 8x card I have coming must be real rare then if it's supposed to be a ti4800.

At any rate wow did nvidia go out of there way to confuse everyone when in the end the 8x really didnt do crap to add performance. Barely a frame more in benches.

"In North America, manufacturers will be marketing their products as 4600-8X cards, while in the European market Nvidia has coined the name Ti4800 for their 8X enabled Ti4600 cards. This is not to be confused with the Ti4800SE cards, which are 8X capable Ti4400s. This confusing array of names is likely to cause stores and consumers no small amount of grief, but those of us in North America can at least rest easy with the fact that manufacturers MUST use the Ti4600-8X nomenclature in our market."

Need to know how to bake or use a heat gun on a ti4200 with memory heatsinks I cant remove.

I suspect it's the GPU die. Card bought on ebay and it white screens with red dots all over the place.

Former owner installed a Zalman gpu cooler on it and tightened the spring nuts too tight and the pcb was pretty bowed inward. The AFP fingers was bowed from it and slight burn Mark's in the center contacts. Was able to clean it up pretty good.

Picture and everything works great till I try to game or benchmark. Min in and white screen.

Tighten the heatsink and it happens quicker.

So hoping I can use a heatsink on her.

Edit: holy crap, I just bought a brand new sealed MSI ti4600 128mb 8x card on ebay! Haha only been checking for years and what a time for one to pop up! Haha.. wife is gona smack me!

Still need an idea about the above issue.

i want to give antipesto93 from ocforums.com the credit for this, he is the one that gave me the idea!

http://www.ocforums.com/showthread.php?t=606658


my 8800gtx died a little over 3 months ago. went ahead and ordered a new video card because i figured the card is completely dead without having to pay to send it in and get it repaired because i didnt register it when i bought it initially(dumb, i know...). anyway, i am posting this message running off my 8800gtx!

i got the idea from another forum, because some guy in the UK bought a dead 8800gtx off of ebay that had red vertical lines through the screen...my card had the same symptoms...one day it locked up on me, rebooted, then locked up on me even quicker...rebooted, red lines all over the screen and windows wouldnt even boot. i tried the card in a friends computer with the same result...

sooooooo, i removed all bits from the card including the i/o shield and placed it gpu side down with the card raised up on 3 sides by tiny balls of aluminum foil and placed it on a very thin cookie sheet. i preheated the oven to 385f, put the card in and waited around 8-10 minutes. i carefully removed the cookie sheet and placed it on top of the oven to cool down naturally. waited about an hour and voila! =D

supposedly this is similar to a trick used to fix dead xbox 360s. some sort of electrical connection gets frail and it eventually fails because of some tiny micro-fractures in solder joints or something....anyway heating the components up helps melt the solder and form new joints.

im now torn as to whether i should sell this card for cheap to someone or keep it as a backup...

akashi_tm
has been kind enough to provide a short, easy to follow video tutorial for the baking process. i would like to remind everyone please do this with utmost caution, care and patience.


Xtreme Bakeover - baking your video card to fix micro-fissures


link to akashi_tm's original post about the video




EDIT FOR LAPTOP BAKING!


it has been a good week for baking...

I bought a laptop with borked video because i was fairly positive it could be fixed by baking...

It is working now after 7m 45s @ 385f in a conventional oven. i noticed a heavy solder smell when pulling the board out of the oven.

PICS!

EVERYTHING WAS REMOVED FROM THE MOTHERBOARD! All protective covers/plastic.

gdonavan was able to get his broken 37" LCD tv to work by baking the mainboard. check out his post!


trick_m0nkey has shown us another method of fixing a dead gpu on a laptop motherboard using a heat gun. check it out here!

such a legendary thread

And the free 37" HDTV is still working like a charm since 2009!
It is currently the primary display for the video surveillance system for the house and garage but does see other duties time to time.

Just threw an M.2 SATA ssd in the oven that quit on me about a year ago. It stopped showing up in BIOS and I just replaced it. I threw it in an m.2 to sata adapter and using an external hard drive caddy, it would show up sometimes in windows explorer, but after navigating the drive for about 10 seconds it would become unresponsive and hang the system until it was unplugged. I soaked it in alcohol last night which didn't help anything, but threw it in the oven and so far it looks like it may be operational again. I ran chkdsk on it and it tested fine. Attempting to image it as we speak since I believe I had some files on there I had not backed up, which is why I've hung onto it for a year.

edit: it worked, backed up completely and I am able to navigate the drive without any problem. 10min @ 400F did the trick! Now I can have a fast boot drive in a non critical machine again :)

I love these stories. Reflowing at home makes me giddy.

Oh, does it release some noxious fumes that stick around in the cooking element? I wanted to try this with an old GPU or two, but if it does something like that I guess it's not a good idea.

Some things will more than others, but yeah, there are some chemicals that go into making circuit boards that would be released with high temps. Some stuff uses lead solder as well. That being said, my SSD didn't have any odor to it at all when I took it out of the oven.

turn on the hood vent and air out the oven when youre done. youll be fine baking a couple things.

I wonder if it would be better to just get a large stainless steel pot with a lid and then put the items inside of it. That way the fumes should be trapped (?).
