Hello, newby here building his first home server.

Got my CPU, Memory and fans plugged into the motherboard and power supply. Powering up turns on all fans but no post, no beep, no bios.

 

Motherboard: ASRock Z170M Pro4s

CPU: Intel Core i5-6600k LGA 1151

CPU Heatsink: Thermaltake CLP0556-B

Memory: Samsung DDR4 2133MHz 8GB (x2)

PSU: EVGA 80+ 600W ATX 12V

 

Here is my fear. I initially did a breadboard build without the heatsink fan installed. I've read online that this could have fried the CPU... Could that be the issue? Anything else I can try to troubleshoot why I'm not getting a post? I realize this might be a vague and open ended question...

 

Thanks in advance!

I have a few suggestions - they are listed below;

 

- Take out the motherboard and check that there are no standoffs where there are no mounting holes. If a standoff shorting out the board is your issue, you may need a new board.

- Re-seat the CPU. Sometimes there might be a pin in the socket that is not making contact with the CPU

- Check that there are no bent/missing pins in the socket. If this is the case, no manufacturer will warranty that board.

- Try using only one of the DIMMs and see if that fixes the issue

 

About your concern with the CPU potentially overheating - most CPUs are designed to withstand up to 100 degrees Celsius. If the CPU wasn't under a load when you didn't have a heatsink on it, it is most likely not the issue.

I pulled the board out, sure enough, there is one standoff without a mounting hole... great...

safe bet that the board is toast?

That is most likely the case. But, I'm curious about the CPU socket. Can you take a picture of the bare socket so I can see the pins?

Looking at the socket, I feel like ALL pins are bent... uniformly. But maybe I'm wrong.

When I close the clasp on the chip to secure it to the socket, it makes a bit of a grinding noise, but keep in mind, as a newbie, this all might be fairly standard.

Other than that, try contacting ASRock and see if they will warranty it. If not, you will need a new board.

The pins are fine - none of them look bent. The grinding noise is normal when you close the retention arm.

Telling them why the board might be shot (the standoff)? or playing dumb and asking for a new one?

Uhh.... I wouldn't play dumb with support. Tell them exactly what happened and see what they say.

Try resetting the BIOS back to factory default; I have had two instances where the CMOS settings were preventing boot. Resetting solved the issue. For bench building, maybe a suggestion here will help.

I realized that my DIMM was ECC while the motherboard does not support ECC... that matters, apparently!

Unbuffered DIMM installed and successful post. Luckily CPU and Mobo are all good!

 

Thanks for the help guys.
