Seller Note: “seller note: Was working until I changed my power supply, now fan spins for few seconds then stops, no output. I tried with old power supply but still the same”
Suspected Issues:
- Excellent general condition / clean
- Sounded like a possible short.
Summary:
- After testing resistances, nothing abnormal was spotted.
- Power on testing, shows a working card!
- The fan is temperature dependent, I would say it could do with cutting in sooner (need to test more extensively)
- Runs a little hot, hopefully new thermal paste is all thats needed before more benchmarking.
Next Steps:
- Need to improve thermals before I would be happy to sell this card.
Analysis
Since card is working (pending more stress tests), there isn’t a great deal to report.
TODO Complete/correct this section anyway in case of similar cards in future and maybe help others.
Pre Checks / Multimeter Only
| Test / Checks | Result | Notes |
|---|---|---|
| 1. Visual Inspection Eye / Magnifying Glass | OK | Appears very clean, no damaged components, very good condition like new. |
| 2. Visual Inspection Microscope | – | |
| 3. Check for shorts on 12v PCI, 12v PCI-E, 3.3v | OK | Couldn’t find any obvious shorts. |
| 4a. Resistance VCore (~0.5 or very low) | ||
| 4b. Resistance VMem (~30-60Ω) | 60 Ω | |
| 4c. Resistance 1.8v Rail (~800Ω+) | Cannot Locate | |
