Guys I'm also having the same issue with the Z170A-X1 board.
I got G. Skill F4-3000C15D-16GVR RAM Mine is also stuck at 2133 ...any time I try to move it up to a faster speed I can't boot my PC. Is there no way that we can get the better performance out of our RAM? I feel like I wasted money buying the faster speed if I can't go above 2133. I got this board specifically because I thought I would be able to use the faster RAM speeds. /sigh

Wait... what...  I just noticed in one of your pictures, the CPU Cache speed is 4200, while the CPU core speed is 3500.  Does the PC boot with things set like that? The CPU Cache speed cannot be higher than the CPU speed. That cannot happen by itself. Was that supposed to be a CPU over clock? Regardless, that needs to be fixed before anything else! This is an excerpt from the Z170A-X1/3.1 Memory Support List:  Find the line with your F4-3200C16D-16GTZ memory, second from the top of 3200 speed. Note it shows "1pcs", meaning one piece, in the column whose heading (that is not shown) is Single Channel. That means only one DIMM may be used at that speed in single channel mode. If you check the memory support list for your board, you'll see as the memory speed becomes higher, the amount of memory you can use is lower, and at the highest speeds, only one DIMM may be used. Sorry to say, your board is not included in G.SKILL's list of compatible board for that model of memory. New UEFI/BIOS versions may enhance memory compatibility, but all mother boards are not built to the same level of ability to over clock memory. Your CPU, and all other Skylake processors, are only guaranteed by Intel to work at a memory speed of up to 2133. Any speed above that is an over clock, that is not guaranteed: http://ark.intel.com/products/88191/Intel-Core-i5-6600K-Processor-6M-Cache-up-to-3_90-GHz#@specifications I know the memory manufactures give the impression that you can simply put their high speed memory into any mother board and it will work, plug and play style. If only that were true. I'm surprised you can't get the memory working above 2133 at all, even at 2400. Are you using the A1 and B1 slots? DRAM voltage set to 1.35V? All memory options besides speed and voltage set to Auto? MRC Fast Boot disabled? Just noticed the CPU Cache clock setting in your picture, moved my comments to the top. How long has it been like that?  |

I've also tried the manual overclock to 2400 Mhz and have the same issue. My cpu is a i5-6600k so I doubt it could be that but who knows. I also don't think I can return this motherboard to the store since I cut off the serial number for the mail in rebate.
By the way I just want to say thank you guys for helping me, appreciate it. Edited by Evilvito - 18 Oct 2016 at 5:11am |

Huh... maybe, just MAYBE your CPU's IMC is utter garbage and can't handle 2800mhz, though I'd be really surprised if that was the case. Try loading all the settings as before, but using 2400mhz or 2666 instead of 2800. See if it boots.

I didn't know that certain memory doesn't work with certain motherboards, figured ddr4 was the same for all. I went and exchanged the ram for something that works with z-170. I bought the F4-3200C16D-16GTZ.
http://www.gskill.com/en/product/f4-3200c16d-16gtz I loaded the XMP profile of 3200 and had the same issue as before. It so far only works at 2133 mhz. By change the bios I meant if I had made any changes in the values in the bios. Edited by Evilvito - 18 Oct 2016 at 3:39am |

Your memory is not listed as compatible with Z170 boards by G.SKILL, only X99 boards. Click on the QVL tab on this page, and then the ASRock entry. If you check any of the other manufactures, you'll only find X99 boards:
http://www.gskill.com/en/product/f4-2800c16d-16grr Fortunately, your memory does function at lower speeds on your board, but it was designed for use with X99/Haswell-E and Broadwell-E CPU systems. As I said earlier, try a speed less than 2800. One other thing to try, set VCCSA voltage back to Auto, which has a small chance of helping with memory meant for X99 systems. Otherwise, you need a different model of memory that is compatible with Z170/Skylake systems. I'm not sure what you mean by "change the BIOS". If you clear or load the UEFI defaults, the default value for the video source is Onboard, meaning the Intel graphics in your CPU. If you mean you just changed the memory settings, that won't change the setting of the video source. In the Advanced screen, Chipset Configuration screen, the Primary Graphics Adapter option is used to select the video source. If you use a video card, set it to PCI Express. |

Still have the same issue after putting in all those values. After I press apply changes and exit the computer will reboot, stay on for 4 secs, automatically turn on for 2 secs, turn off again. Turns back on but I get no display on my monitors. I then have to reset the bios to get it at 2133 mhz Ram in order for me to see something on display.
I took pictures in case I missed something Here is the main page showing that my RAM sticks are in A1 and B1  Putting the ram to 2800 MHz  Disabling MRC fast boot  And lastly the voltages  This may sound dumb but when I change the bios, does it automatically put the display on the inboard video card?

My ram is G Skill 16 GB (2 X 8GB) Ripjaws 4 2800 MhZ ( F4-2800C16D-16GRR), rated at 16-16-16-36 at 1.20 Volts.
I too happen to have them on the A2 and B2 Memory slot. I will switch them to A1 and B1 and see what happens. I'll be back here to post results. Not sure if this matters but the Ram model above is what my retailer/sticker says while the Program RAMExpert tells me the model is Fujitsu F4-2800C16-8GRR.

What is the exact, full model number of your memory?
I can't tell from your first post if you have 4 x 4GB DIMMs, or 2 x 8GB DIMMs. Is all 16GB from one kit of memory, or from two kits, etc? We need to check your memory for compatibility, and hopefully not a mix of multiple kits. That is not always an issue, depending upon the manufacture. Given the DRAM voltage I see with the XMP profile enabled, you might have Crucial memory. If you have 2 x 8GB DIMMs, they should be put in the A1 and B1 memory slots. In the UEFI, DRAM Configuration screen, all the way on the last page of that screen, find the MRC Fast Boot option. Set it to Disabled, which will enable Memory Training. That helps with higher speed memory. Your board does not seem to have a VCCIO voltage option. That is not critical. You can increase VCCSA from its Auto value, but I've found you don't need 1.20V for the VCCSA with even higher speed memory. Try 1.15V, and if you get 2800 to boot and is stable, you can slowly reduce it from there. You can try disabling the XMP profile, set the memory speed manually, and have all the other memory options set to Auto (except MRC Fast Boot.) Set the DRAM voltage to 1.30V, since the XMP profile seems to set it to 1.25V. Using the manual memory configuration method above, try increasing memory speed in steps. Try 2400, 2600, or 2666 before 2800. Hint: If you want to post pictures of your UEFI screens, put a USB flash drive in a USB port on the board's IO panel. When you are in the UEFI on a screen, press the F12 function key, and the current image on your monitor will be written to the USB flash drive. You can look at those pictures, or use them in a forum post. |

On the motherboard manual, it says VCCIO in the Bios table (though it doesn't tell me where). From what your saying
VCCSA voltage = 1.2 volts Ram voltage= 1.35 volts Also I'm keeping the XMP 2800 mhz profile on? Edit: It seems like the only voltage numbers I can change are?<span style="color: rgb7, 15, 20; font-family: Verdana, Tahoma, "Nimbus Sans L", arial, sans-serif; : rgb243, 244, 246;">DRAM voltage,Vccsa CPU Vcore voltage and GT voltage.? It won't let me change anything else you see.?</span> Edited by Evilvito - 17 Oct 2016 at 10:13am |
