ground Posted July 17, 2020 Share Posted July 17, 2020 (edited) currently have 3 dead/damaged rex here. #1 - dead vcore fujitsu + some conductive thermal paste near NB shorting the nb vrm. Board appears to be working fine again. #2 - dead vcore fujitsu, vcore shorted to 12V. Found dead mosfet, replaced it + driver + controller, it blew straight up again. with lab psu it goes beyond memory training during post, so I assume with proper epower it should work properly. #3 - dead vcore fujitsu, vcore not turning on. lots of corrosion. With controller removed + epower it doesn’t attempt going beyond 00. other unnecessary chips have been removed. tried powering SB with lab psu to check current draw, it only draws 15mA at 1.05V which seems very little. Suspicion is dead SB but beyond that no idea. resistances appear normal on all 3 boards after faulty parts have been removed/fixed.
