Idea is the following:

Across an agp riser, an estructure and with a multimter to measure voltage pin by pin (gold test socket pin) and later to compare it with my Rampage. I still thinking the Rampage Chip does not get the right voltage. If I find what pin is not good I can follow traces and check what V-rail is doing the problem and work there.

Main problem- I dont have enough time free to work there. Summer is very busy here.

Rampage CHIP re-balled with great success. It works perfect with new balls. Rampy #B001 comes back his original stated.

Not too much time for working on Rampy but the most important is 4 POWER RAILS gives the right power, one for CHIP the others 3 for DDR memory. This is the most important. Only I wish the card has not broken any internal trace.

Regards,
Oscar.

Now, I need to find where is the SWITCH makes the card wakes up. Now testing values Ohm across of each pin/pad hoping to find an alterated vaule that can show me the way. Regards, Oscar

This afternoon I will follow the trace from the pad and I will see where it goes. I hope to find the problem there. Regards, Oscar.

FOUND THE PROBLEM- I checked pad by pad with a multimeter set in ohms until I detected an anormal value. Following the trace I detected one resistor 100ohm soldered in wrong place. I unsolder and solder it in right place and voila!!! Card waked up!!!! We have antoher 100% functional card!!!

Really I still cant believe it!!!! Cheesy

ps. My friend you already own a 100% fully functional Rampy card. EnJoy it and take care of the QUEEN!!! Cool
