Hi,
Just gonna say a big thanks to you guys. From the info on this site I was able to repair my AOpen AK77-600 Max board. It worked for 4 years then developed random crashes.
I checked the board and all the 2200uf KZG caps in the CPU VRM had failed. I replaced them with Panasonic FC's and prime95 has been running for 12 hours now with no problem and vcore is rock stable.
As an interesting aside, the mobo manual devotes 2 pages to these caps, describing them as:
"The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation."
Regards,
Achelon
