send it to me and ill reflow it for you for free. I fix E74's all the time. But ewww@ them quick fixes you did. I tell everyone to stay away from them xclamp fixes. Its not the xclamps that cause the red ring,its the cheap ass lead free solder used under the GPU. a good reflow should last you til the 720 drops.
Unrelated to the thread, but we switched to that lead free bullshyt at my job like last year. i fukking hate it b. shyt takes forever to heat up and it flows like shyt...and its shyt on components...everything looks like a fukking cold solder joint
