[quote]So I got Macfixit email quoting this from this thread:[br] Gunnar Forsgren wrote: Apple has declared these machines end of life so the days of class action suits is done with. But the best solution I found is sending the laptop in to guys who replace the GPU chip on the motherboard with a revised design new one. End of problem as long as overheating issues can be kept in check. ==============[/quote] WHAT GPU chip has a revised design, please? Last time I got mine replaced, I got this one:[br] [br] AMD Radeon HD 6770M: Chipset Model: AMD Radeon HD 6770M Type: GPU Bus: PCIe PCIe Lane Width: x8 VRAM (Total): 1024 MB Vendor: ATI (0x1002) Device ID: 0x6740 Revision ID: 0x0000 ROM Revision: 113-C0170L-573 Automatic Graphics Switching: Supported gMux Version: 1.9.24 EFI Driver Version: 01.00.573[br] ============[br] [br] And a year later I’m starting to see flaky behavior again. Where, oh, where is the source for a reliabl fix or replacement? Detailed answer please, as I foresee sending my late 2011 17” hi-res off to someone fairly soon, again.
