do you use the stock pre-programed profiles or do you have modified profiles?
my own. The humidity, temperature, and other factors of where ur machine is makes each persons profile uniquedo you use the stock pre-programed profiles or do you have modified profiles?

Reballing is THE BEST fix for RROD/GPU failure because it actually FIXES the problem instead of making it worse like the "xclamp" "fix" or a heatgun, etc. These fixes are all TERRIBLE ideas because all causes irreversible damage to the components on the board along the GPU.
When RROD happens its because little .6mm balls under the GPU have a bad connection or merged (think of them as cutting a wire). There are hundreds of these under the GPU and it only takes 1 to mess up to brick your console. Reballing replaces ALL of the spheres under the GPU to ensure a brand new connection between the board and GPU
Why the xclamp "fix" isnt a fix: The xclamp "fix" is basically tightening the heatsinks so the pressure between the board, chip, and heatsink becomes extremely large in order to make a "better" connection with the board. This isnt fixing it at all because the failed connection is still there and has not been sealed (like holding 2 wires together instead of soldering them) Although this might fix your problem this immediatly damages your console and every time you run it makes it worse and worse.
Short version: So much pressure causes micro fractures on the GPU, warping of the GPU, warping of the motherboard among other things that PERMANENTLY DAMAGE YOUR CONSOLE. Your console WILL fail again
Technical Version: Increased pressure on the BGA + GPU causes a so many problems heres a few:
1. Thermal stress: Not getting into thermodynamics but more pressure along with heating cycles causes GPU fractures, cracking, and permanent damage too it
2. Board warping: so much pressure from the 4 bolts on the board can cause it to warp under the GPU. This leads to #1 along with your board being permanently damaged.
*Note: I use the bolt mod often called the xclamp "fix" however there is NO overtighting of the bolts. Just enough pressure on the GPU to provide a thermal connection between the GPU, Thermal Paste, and Heatsink in order to disapate heat
Why heatgunning is bad!!!!:
Question: What store would you go to in order to fix you electronics?
a. Chipotle
b. Home Depot
c. Best Buy
d. Radio Shack
Well why are you going to Home Depot to get a paint melting gun to fix something as fragile as a GPU!?!?!?!
Problems:
1.Uneven heating from gun: leads to #1 #2 above.
2. Popcorning of GPU (dead GPU) ---> only option is reballing a new GPU
3. No temperature monitoring: A successful reflow involves hitting the desires temperature (217 celcius) with an even temp gradient along the GPU. A heatgun cannot come close to this.
Although a heatgun may fix your GPU failure your problem WILL come back again.
Why Reballing is a permanent fix:
When MS made the xbox 360 they used exclusively Lead Free solder on the whole board. Although this is perfectly fine in most situations, Lead Free solder is not as thermally stable as leaded solder. Since MS failed at cooling the GPU heatsink and used terrible thermal paste the GPU goes under extreme temperature changes that weaken the BGA (solder spheres) under the board causing cold solder joints and bridges.
Reballing involves removing the GPU chip and cleaning off ALL the lead free solder on the board and GPU in preparation for Lead Solder spheres to be used for a more thermally stable connection in addition to better pressure on the GPU (NO OVERTIGHTING) and high quality thermal paste in order to properly draw heat away from the GPU.
Reballs on consoles that have not been heatgunned, xclamp "fixed" can normally last 1+ year.
Yes as the original solder balls are non leaded, you would replace them with leaded solder balls (higher melting point than unleaded). Also a person can get stencils for all the chips that are BGA, just hafta make sure that a person gets the correct mobo revision.So you permanently fix RROD by reballing JUST GPU? Inb4 RAM breaks, CPU breaks, (H)ANA breaks.
