Z170 Extreme7+ not rebooting

One name. G.Skill.

They don't pass the buck. You have questions, they have answers.

Here's the link to memory that G.Skill themselves have tested on your MB. Compatibility is guaranteed.

And did send them a ticket asking about the compatibility.  Should get back to me in a day or two.

Your MB Manual will show you which memory slots are A1 and B1.

Looks like my type and speed of memory is supported up to 8gb sticks but the 16GB sticks aren't listed. Could be not labeled as compatible or they just haven't updated the list since the 16gb chips have come out I don't know.

When I try to reboot or start it up and it doesn't post the code on the board gets stuck at 55.  Any idea what could be causing this?  Would a bios update fix the problem?  Is this a known issue with this board?  Would really hate to have to disassemble it all and RMA it or return it if its something I can fix.  Very aggravating issue that while I can work around I really don't want to have to.

Your problem is not a known issue with this board. I have this board, and mine does not do what you described.

Your board is this model: http://www.asrock.com/mb/Intel/Z170%20Extreme7+/

What UEFI/BIOS version are you using?

We need the full model number of your memory to check for compatibility, which you could check with the link wardog provided, or check the Memory Support list on your board's information page, above.

No idea what speed your memory is, the greater the memory capacity being used, the more difficult it is for the CPU's memory controller to deal with. Are you using the XMP profile?

DIMMs greater than 4GB in size should be used in the A1 and B1 slots.

What version of Windows are you using?

In the UEFI/BIOS, OC Tweaker, DRAM Configuration screen, all the way at the bottom of the screen, setting the MRC Fast Boot option to Disabled. That will cause memory training to occur during POST, which may help with the 55 POST code.
