Device : Dell N4030, DJ1 Discrete Ver : 01 Problem : Over voltages. 3.3v : 3.7-4V. 5v : 5.20V 3.3V ALW : 3.30V 5V ALW : 5.05V Vga Core : 1.50-.160V (Too high Ati 216-0774008) Cpu(62882HRTZ) : 1.52V RAM(RT8207GQV) : 1.80-2.10V PCH VTT : 1.40-1.80V It came with short circuited network chip(lan) and usb power cores. Chipsets were heated. Power button was runnig but there was no video and beeps. So I changed these parts; -Atheros ethernet chip -USB Power Cores -EC Nuvoton NPCE781BA0DX -Reflashed EC, Main flash. -HM57 I heard error beeps but no video -ATI 216-0774008 Finally I see startup screen but now it started to blue screens. I tried with 65W and 90W power supplys still same. When the card is cold voltages are normal for 10 seconds and then gets higher. Second changes, Sys Charger = BQ24745 (I fixed this situation before by changing sys charger on dell n5010) DDR voltage = RT8207GQV 3.3-5V Core = (RT8205B(CK=XX)) Cpu Core = 62882hrtz Voltages are still same. Can somebody tell me what is wrong with this motherboard... |
