well, it's been some time since my 1st Pulsar complained about a 'Ram error' and didn't initialize anymore.
As this card carries most of my licenses, some even unrecoverable, it was a pretty pity.
I even bought a heatgun to replace the chips, but never dared...
Anyway, inspecting it closely revealed one of the 4 caps beneath the voltage regulator had come loose. They sit close to the 2 Ram chips and seem to buffer those.
Resoldered and it was up working again
So if anyone runs into similiar messages, it may not be the part itself failed, but something more simple connected to that part...
cheers, Tom
