Now you need to check the health of all mosfet's from pq711 to pq742 source-drain, and maybe change pwm u3017. Do you have an oscilloscope? |

here - vr_ready, it is - pwr_good. if voltage is ok - this pin HI. if no power on CPU - is LOW. look around pwm - smd elements is ok? |

check rp892, rp942. and resistance from GND |

rp892 in 2.0 mega ohm also 2ohm Posted after 3 minutes 40 seconds: rp942 it is 2.7 mohm |

ok ,i will do it ..Also i have some problem on one board asus p8h61-mx when turn on i have beep code no ram ..I have check slot voltage everthing is ok ?maybe you have some idea? |

check socket - all pin must be ideal. change CPU and RAM. check 3.3v on pin 236 all ddr slot's. if no result - made new post in asus motherboard. |

aleksros intel DX79TO Maybe you have schematic or board view ?I dont have enable on pwr controller and cant find from come from signal.I search but i colud not find board view.. |

no, I don't have schematic or boardview for Intel motherboard. |

aleksros hi ,i please you if you can help for some problem ..I have motherboard ga-h61m-ds2 ,I will send you schematic because no board view for this model..Ok ,problem is that on phase CPU coming instead 1.1 v is 2.7v , I folow vcore line also is 2.7 v ,I alredy have change PWM controller but same ..I never before have this problem ,very strange..Maybe you can advise me ..PS VR-on is ok 1.1 V.. Posted after 16 minutes 32 seconds: this is pictures of motherboard and voltage .. |

are you have oscilloscope? you have to see pulse voltage on DL2, DL3, DL5. not constant voltage, pulse - is ok. look around PWM DU1. SMD elements must be ok. no scratch or damage. |

| bokin021 [ 09 фев 2019, 00:25 ] | |
| Заголовок сообщения: | Re: problem asrock z97 killer |
no,i dont have oscilloscope ,but any way is to hi voltage?I have watch around but, nothing is damage ..,there is maybe another way ? |
|
| aleksros [ 09 фев 2019, 00:49 ] | |
| Заголовок сообщения: | Re: problem asrock z97 killer |
yes. 2.7v - it's to hi. measure all mosfet's gate-source, drain-source. measure all smd near pwm du1 and voltage on pwm du1 pin's from 1 to 40 (page 27). |
