As inspired by "Actually Hardcore Overclocking": Power bridge mod testing.
Mod basically bridges not-switching inductor leg, with vGPU pads under chip. On such low power GPU it's not very effective, however it was fun to made.
As material i used solid copper wire of fi=1.5mm in heat-shrinking black isolation.
Here are some data:
| Power Loss |
||
|---|---|---|
| Before Rail | After Rail | |
| Idle | 2.25mV | 0.45mV |
| 1% Max | 9.3mV | 2.9mV |
| 100% Load |
9mV | 2mV |
| GLMark2 Score | 585 | 587 |
