POST error GA-B150M-D3H -- five beeps

[arby10101]

I have a new build with a GA-B150M-D3H, Rev. 1 and an i5-6500. On initial boot attempt, I get five POST beeps.

The old AMI BIOS beep codes say that 5 beeps means CPU failure. A current list of UEFI codes from AMI shows "No Console Input or Output Devices are found."

I won't go through the static and handling precautions I took but I'm confident I caused no CPU damage. For the second possibility above both input and output devices are known good from other computers.

Question 1: Is a bad CPU the most likely problem? This is, I think, my 11th build over 15 years and never had a bad CPU before. I've tried re-seating, visual inspection, compressed air, etc. Both the chip and the socket look perfect.

Question 2: Is there a way to determine whether the problem lies with the CPU or with the motherboard? I don't have a PCI checkpoint card (POST card).

Thanks for any information or advice.

What are you using for memory? We have seen a lot of problems with any thing over 2133 memory.

Memory is G.SKILL Ripjaws V Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000). Those are the same units listed on the "works with" memory list except Gigabyte lists the 16 GB part number.
