|1. Observations (e.g. PCB heat noticed, |
blank screen, power light on monitor,
bios screen, o/s loaded, artefacts, )
|Have BIOS picture. Blank screen on driver / windows load. Area behind GPU quite hot, a despite quite large heatsink it is necessary to run the fan to avoid a very hot GPU after several minutes. Passed MATS memory test.|
|2. Voltage VCore (~0.88v)||0.9+ OK|
|3. Voltage VMem (~1.4v)||1.5 OK|
|4. Voltage PEX Rail (~1v)||OK|
|5. Voltage 3.3 BUS||OK|
|6. Voltage 12 Ext||OK|
|6. Voltage 5v Rail||OK|
|7. Voltage 8.8v Rail||–||–|
- Resistances and voltages seem fine, although worth checking voltages more closely in case of power stage issue.
- BIOS screen fine, no artefacting seen, passed memory test, cannot load driver – possible GPU issue.
- Hot behind GPU – Will repaste.
- GPU is GF116-400-A1
- Memory is Hynix 2 different codes
Update: After cleaning and repasting, now there is no picture! All voltage appear present and the GPU area gets pretty hot. I am starting to think this is probably a GPU issue, possible reflow / replace candidate. The card was not expensive and it’s resale value isn’t likely to be much even if fixed. I also don’t think this is a particularly great type of graphics card i.e. doesn’t seem much better than a GTS 450 and doesn’t have great thermals.
Update: A day later, the card seems to display the BIOS screen reliably, attempting to boot windows results in black screen and reboot. I have rechecked the voltages, which seem ok. If the card is fine from a power delivery perspective (not 100% sure) and the memory is ok (test passed), then the GPU seems the main suspect.
