I have no image with memory mod. the 5v drop down to 2.5/2.7 in pin8 of each memory/slot. Is this value under load ok? ..mmmmmm
Removing the 4516 ic the system "start" with black screen. And the chips are very hot after a few minutes on.
The mod is about quit L2 and L3 and join +5v point. May be a part of the 5v is lossing on the way, may be a short circuit. But with 4116 are no problem. The system start normally.
