Hello everyone, I'm a bit stumped on this one. I have a new build (my 2nd ever) I put everything together and then plugged in the power flipped the switch on the psu and I get LEDs on the board. I press the power button no luck. No fans spin no beeps no visual changes. I took everything out put it back in. Replugged every cable still no luck. I then took it out of the case and plugged in cpu and mobo power and had the motherboard on a cardboard box. Ram in a2 and b2. Then did the screwdriver trick with the pins. No luck still no fans nothing. I returned the board and got a replacement. Rinced repeated. Still no luck (did cardboard box setup as explained above). Thermal paste was applied properly it wasn't overflowing to pins. No bent pins (at least that I can see). I was very careful took precautions and worked slowly. Any help or advice would be greatly appreciated. Specs below: Cpu: Intel I7-8700k Ram: Corsair vengeance LPX 16 gb ddr4-3000 Mobo: Asrock z270 extreme 4 Psu: EVGA supernova 750 watt |

" rel="nofollow - Ummm..... I don't know how to tell you this, but you are using a CPU and MB combo that WILL NOT work together. https://www.asrock.com/support/cpu.asp?s=1151&u=1041 |

" rel="nofollow - Yeah that sounds like something I'd do lol. I thought I double checked and saw it would match up. Guess that's on me though. Thanks for the fast reply it's greatly appreciated. Is the cpu most likely dead now? |

The CPU should be fine. As far as I know, the only reason 8th gen does not work on 100 and 200 series boards is because they need more power, they are pin compatible and no, there is no different mapping to the pins. All this means that the CPU should still be OK so long as you didn't damage it when assembling/disassembling the system. Pick up a Z370 board and you should be fine. -------------

The 8th gen is software locked from working on z270 boards, they require more power to work, so if they were not software locked, the 8th gen would boot in a z270 board, but once you pushed the cpu, when it needs need more power, then the system would not be stable and then you would have problems! That why they were software locked!

Yup, it's already been proven that the 8th gen i3s work on even Z170 boards, an ASRock board no less. It requires some serious messing around with the BIOS programming but it has been done. I wouldn't recommend it, no doubt the unofficial nature of it will cause issues but it is interesting none the less. I may give it a look myself if I can pick up an 8th gen i3 on sale, I have a few 100 series boards laying about I could try it out on. An 8th gen i3 with 16gb of DDR3 could be interesting. It's a pity we won't see any official support, I highly doubt intel would allow it. -------------
