PLEASE READ THE ENTIRE DESCRIPTION BEFORE PURCHASING. THIS GRAPHICS CARD IS BEING SOLD AS FOR PARTS OR NOT WORKING DUE TO PREVIOUSLY REPORTED INTERMITTENT ISSUES.Up for sale is a ZOTAC Gaming GeForce RTX 4070 Twin Edge 12GB GDDR6X graphics card.The card was originally removed from a working system and tested without issues. However, a previous buyer reported intermittent display failures and system crashes. After receiving the card back, I performed additional testing and was unable to reproduce the reported problems.Because the cause of the reported failures remains undetermined, I am selling this card AS-IS, FOR PARTS OR REPAIR, at a discounted price rather than listing it as fully functional.Previous Buyer's Reported IssuesThe previous buyer reported the following problems while using this graphics card:Both monitors intermittently losing display output while the rest of the computer continued running.System crashes, freezes, and unexpected restarts.Windows Reliability Monitor showing multiple NVIDIA-related GPU timeout and failure events.LiveKernelEvent codes 117 and 141.A 0x116 VIDEO_TDR_FAILURE blue screen referencing nvlddmkm.sys, NVIDIA's display driver.The buyer also reported testing the PCIe connection at Gen3.A screenshot of the Windows Reliability Monitor hardware error was provided, referencing a GPU timeout involving the NVIDIA driver.These symptoms could be caused by the graphics card or other system-related factors. The exact cause has not been identified.My Testing After the Reported IssuesAfter receiving the GPU back, I conducted several tests to investigate the reported failures.Testing included:30-minute Vulkan graphics stress test – Completed without a reported GPU validation failure.27 GPU load/idle transitions – Completed without reproducing the reported issue.15-minute CUDA and OptiX Blender workloads – Completed without observed GPU errors.GPU memory stress test – Ran for 40 minutes and 22 seconds before stopping due to a sensor-logging failure. Saved test results showed no memory validation errors before interruption.10-minute idle monitoring – No reported GPU failures.During the completed tests, I did not observe GPU artifacts, graphics-driver resets, GPU device loss, or the display failures described by the previous buyer.Important: These results do not prove the card is defect-free. The buyer's reported failures could not be reproduced during my testing, but intermittent problems may still exist and could occur under different conditions.Physical ConditionTwo screws securing the fan shroud to the heatsink are missing.The fan shroud remains attached.Minor cosmetic handling marks on the backplate.Graphics card only; no original box or accessories.SpecificationsModel: ZOTAC Gaming GeForce RTX 4070 Twin Edge (non-OC)SKU: ZT-D40700E-10MGPU: NVIDIA GeForce RTX 4070Memory: 12GB GDDR6XInterface: PCIe 4.0 x16Display outputs: 3x DisplayPort, 1x HDMIPower connection: Single 8-pin PCIeIMPORTANT – AS-IS / FOR PARTS / NO RETURNSTHIS GRAPHICS CARD IS SOLD STRICTLY AS-IS, FOR PARTS OR NOT WORKING, WITH NO GUARANTEE OF FUNCTIONALITY, RELIABILITY, OR STABILITY.Although I was unable to reproduce the previous buyer's problems, there is a documented history of intermittent display failures and system crashes.The buyer acknowledges and accepts that:The card may function normally, experience intermittent failures, or fail to function entirely.The previously reported black screens, driver timeouts, crashes, and system restarts may occur again.Other hardware or functional problems, including problems not discovered during testing, may exist or develop.My testing results are provided for transparency and do not constitute a warranty or guarantee of future performance.The card may require troubleshooting, repair, or replacement of components.No warranty is provided.
