Defective Asus GTX1070

TL;DR

I recently purchased an Asus GTX1070 which booted, POST'd (sort of) but would not load Windows 10. It was defective and a replacement sorted it out.

The most important symptom is the BIOS/UEFI POST being in the wrong (non-native) resolution.

Long version:

I tried 30+ hours of changing settings, trying different things.

  • turning off Windows Fast Boot
  • UEFI only booting
  • non-UEFI legacy / compatibility only booting
  • Isolating the hardware in two machines to bare minimum (disconnecting SATA devices etc)
  • Two fresh installs of Windows 10
  • At least 4 different versions of the Nvidia Drivers, using DDU to uninstall the previous drivers in Safe Mode between installs.
  • Modifying window's power settings to maximum performance
  • turning off onboard Audio in BIOS
  • turning off VT-d in BIOS
  • running on a known-good installation of Windows 10, as well as a fresh install (twice)
  • resetting BIOS to defaults by clearing the RTC clock jumper and the RTC battery
  • Pulling and replacing RAM
  • Upgrading the Motherboard BIOS on both tested machines to the latest official bios versions.
  • Checking with the official ASUS tool that the Video Card VBIOS was up-to-date (which it was)
  • Updating Windows 10 to version 1709 (Fall Creator edition)
  • Changing the monitors, and trying different HDMI and DVI-D cables.
Nothing worked to alter the outcome.

In the end it was just defective card.

My motherboards were an Asus P8Z68-M PRO and a Asus H97-M Plus

Blender Skeletal Mesh Export to Unreal Engine 4

Notes on exporting animations from Blender to UE4

The FBX exporter takes note of where the meshes are when the exporter is run. Therefore it is important to have a frame selected (frame 0) that represents the Meshes in "normal" state.
Skeletal mesh will read which frame is currently selected when the exporter is run.

UE4 - Re-importing will work for mesh geometry changes.

UE4 plays animations back at 30FPS. Blender Defaults to 23.98, set it to 30 FPS.


Character Interaction
* Character Interaction requires a 1m offset in the mesh for doors
