4890, Powercolor. But yes, reference.
I learn something new evertime I start browsing here reading that is quite excellent advise I am shocked I never thought about it untill I read your post.:nerd:
Sadly I somehow damaged my 4870 While doing this procedure. I've cleaned loads of cards. And everything went well until I put it back in the computer and turned it on and lines were all through the screen ;(
Sorry to hear that but the next time just use a can of compressed air every few months. Oven time or RMA it is then. DON'T NECRO
I gotta buy that electric duster, I'm using like 20€ a month on air dusters atm...
Don't use oven to bake your graphic card, there is less than 50% chance for procedure to work and you can damage capacitors (most of them are 105 Celsius rated, and you must use temperatures above 200 Celsius!) or plastic parts on graphic card.
Instead use this procedure: http://www.youtube.com/watch?v=by4yJ4fpJig ...with few modifications:
1). Instead HotAir station you can use Heat Gun with good temperature and airflow controll like Skill 8004 AA: http://www.skileurope.com/general/en/diyocs/Tools/1199/1023/heat-guns/heat-gun/ ...and use hot air reduction nozzle with tool like that.
2). Isolate all parts around graphic chip with 2 layers of alu-foil
3). Don't warm up PCB or any other part od graphic card around GPU
4). Don't use temperatures above 350 Celsius, guy on video uses 420 Celsius but there is no need for that, 350 Celsius @ max will be quite enough. So, on part of video where he is using 420 Celsius I recomend you to use maximum 350 Celsius. Air from HotAir station or Heat gun nozzle is always hoter than chip below, that's why you need to use a bit higher temperature of air to be sure that tin ball solders between GPU and PCB are melted propperly.
I always use one of these http://www.parkcameras.com/9264/Gio...rrer=Froogle&gclid=CNPR1-mD7rgCFU3LtAodmz4AgQ
In fact, that's the exact one I'm using.
Heavy guns here, I use something like this: http://www.google.rs/imgres?client=firefox-a&hs=ZcS&sa=X&rls=org.mozilla:en-USfficial&biw=1274&bih=891&tbm=isch&tbnid=MTaW8hNGsRQElM:&imgrefurl=http://www.garagejournal.com/2006/07/air-compressors/&docid=q0UZbrmJ-6bxBM&imgurl=http://www.garagejournal.com/wp-content/uploads/2006/07/compressor.jpg&w=400&h=280&ei=qKkDUtj4C4vAswbFnoG4DQ&zoom=1&ved=1t:3588,r:51,s:0,i:238&iact=rc&page=3&tbnh=188&tbnw=268&start=51&ndsp=29&tx=156&ty=58 ...when I turn that beast on mine dogs and cats and other dogs and cats in neigbourhood simply freak out
Sadly none who sell that electric duster will ship to Finland. Guess I'm stuck with air dusters.
I may be able to find my 4870 that I used a few years back if you are interested. Let me know and I will look.
