Power On / Test Rig Checks

Tests / ChecksResultNotes
1. Observations (e.g. PCB heat noticed,
blank screen, power light on monitor,
bios screen, o/s loaded, artefacts, )
No picture.
No fans.
little heat (GPU), some warmth around back of VRM area.
Hard to probe with heatsink, hopefully safe to investigate with a small passive heatsink. There are voltages, GPU gets hot over time (>5 mins)
2. Voltage VCore (~0.88v)0.9vOK
3. Voltage VMem (~1.4v)
4. Voltage PEX Rail (~1v)
5. Voltage 3.3 BUS
6. Voltage 12 Ext
6. Voltage 5v Rail
7. Voltage 8.8v Rail

GPU: Antigua PRO (215-0877000) This is available, but quite expensive (Aliexpress £45)
