Hi, My iMac’s model is A1312-100 EMC: 2374. Where can I find if this iMac has a replaceable GPU? Thanks on advance

Your system is one of these EveryMac - EMC 2374 Here’s the procedure to replace your GPU MXM board: iMac Intel 27" EMC 2374, AMD Radeon HD 4850 Video Card Removal & Repair And here are the MXM boards the system came with: ATI Radeon HD 4670 with 256 MB - Apple P/N 661-5314ATI Radeon HD 4850 with 512 MB - Apple P/N 661-5314 You’ll need to clean off the thermal paste and apply a fresh coat and the VRAM chips thermal pads will need to be replaced as well. I do this even if I get a replacement unit with a heat sink attached.
