Seller Note “untested, suspected faulty”
Summary
- Voltage rail issues, found 3.3v, 1.8v, not 12v, Vcore and Vmem both very low ~0.5v. Needs dismantling and thorough resistance/voltage checks)
- Resistances
- Vcore – 0.5
- Vmem – 59.7
- PEX – 11.5?? Not sure if this is PEX
- 1.8v – 5K
- 5v – 1.3K
- 12v – 6M
- 3.3v – 3.6M
- Voltages
- Vcore – 0.7+v OK, the core is getting warm, not hot
- Vmem – 0v
- PEX – If this coil is PEX it has 0v
- 1.8v (present)
- 5v (present)
- 12v (present)
- 3.3v (present)
Investigate Vmem 0v
Not sure, but perhaps a lack of Vmem voltage means no PEX either.
