I ment to say it is a V2 board On a V1 they are not there

These are caps for the second power rail for the RAM chips. V1 has only two the V2 has four.
They help to smooth the power and even out the power delivery over the two RAM chips.

That corect after I checked a V1 board I noticed this that has two.

The diode reafing I am getting on the V1i and v2 boards is very low 0.179 approx

Is this normal I be thinking it is very low and should be up around 0.3

Could anyone verify the diode reading across these caps on a good power up switch-Thanks

6

Diode mode readings at those caps should have 0.180V drop
