Fatal1ty Z170 gaming itx/ac wont post

Greetings ASRock forum, 
So I got this board at first a week or so ago.  Here is the full list of specs that I am trying to put together:

MB: ASRock Fatal1ty Gaming Z170 ITX/ac  BIOS version P1.50
CPU: Core i5 6600K unlocked socket LGA 1151
CPU cooler:  Corsair H100i
RAM: G.Skills Ripjaws V DDR4 3000 2x8GB
PSU: Corsair 750W modular PSU (yes I know it's probably overkill)
GPU: MSI Radeon R9 290X
Case: Corsair Graphite 380T
Monitor: Asus MG279Q connected via HDMI

So the problem I have had since I got this board is that it apparently doesn't post.  I get no video signal coming to the monitor via either HDMI port on the board.  I am trying to breadboard start it outside of the chassis, with just the RAM, CPU, PSU, and CPU cooler hooked up.  I hooked up a speaker to the board for troubleshooting.  If I start the board (using the cases switch), then the fans all turn on but I get no signal output via either HDMI slot.  If I start it without the RAM, then I get 3 long beeps from the speaker that pause and then repeat.  I tried putting just one stick of RAM in either slot in all possible configurations, but no joy.  I never got any other beep codes while changing RAM configurations. I tried to put in the GPU while breadboarding to see if I could get video output from there.  Unfortunately, that didn't work either.  I tried multiple displays, but couldn't get output on any of them.  Not sure where to go from here.  I RMA'd the board initially last week, but clearly that wasn't the issue.  I'm on my second one now.  I tried it with another PSU that works and got the same result.  I thought it might be the CPU, but that seems highly unlikely.  It is a brand new skylake processor. I really want this board to work because of the features, but I'm getting really frustrated with it.  Any suggestions are welcome.

	Sorry but must ask, is the 4/8 pin CPU power cable connected to the board? The board will not POST without memory installed. Every time major hardware is changed, like memory to different slots, or adding/removing a video card, the UEFI/BIOS must be cleared. Try one DIMM in the memory slot that is the farthest from the CPU. The BIOS version that is on your board is shown on a white sticker on the BIOS chip. What version do you have? Your memory might need a later version, but I don't know exactly. Did you look at the CPU socket for bent pins?

	Yes, the CPU power cable is connected. I went through the whole Tom's Hardware forums checklist. I have tried using a single DIMM in either slot with both DIMMs that I have available. I get the same result every time. I did examine the socket for bent pins and could not see any. I actually suspected that BIOS version might be a problem. I will check the BIOS chip when I get home and update the thread with the BIOS version. I thought it might be an issue because the specific serial number of that memory kit is not one of the ones that was tested by ASRock on their QVR. I thought it should work anyway, but it seems newer than most of the ones on their list. Additionally, I have another kit coming tomorrow that is on their QVR by serial no. (HX421C14FBK2/16). Hopefully that will work so if it is a BIOS issue I can flash it and then use the other RAM that I originally wanted. (Edited original post to include BIOS version) Edited by KingTruffle - 29 Jan 2016 at 8:10am

	So I tried out the Kingston hyper X with the same result. I made sure to clear CMOS first, but I still have the same issue as before... Not sure what else I can do.

	The 6600k should have been supported since the release BIOS so with 1.50 you should not have CPU compatibility issues. The 3 beeps when there is no RAM installed means the board begins the post process and is probably working. Unfortunately that board does not have a DR. Debug LED display so we can't tell where the system is getting hung up. You can try removing the mini PCIe Wireless card and disconnecting mouse and keyboard from the system. Basically try and power up with just the CPU/cooler, 1 module of RAM and PSU connected. It is rare but on occasion USB devices connected to the system can cause Post failure. Your issue sounds like RAM compatibility problems but you say the new kit is on the support list so we need to dig deeper to determine what is happening. It is very unlikely that 2 boards could be dead in the same exact way so maybe it is time to examine the other components. If the above does not work then remove the CPU and examine it thoroughly for damaged contact pads/debris as well as check the socket for bent pins/debris. Also make sure the RAM is firmly seated into the slots, on my recent review of the H170 combo I noted that the DDR4 slots in particular were a very snug fit and it took a little more force than I am used to in order to seat the RAM. Obviously within reason With the board out of the system you should easily be able to see if it is seated correctly though. It may also be worth clearing CMOS using this method. It should ensure that the CMOS is fully cleared. Also, you can try not replacing the battery for the initial power up after the clear. If the battery is damaged or defective it could cause post issues. It is possible that 2 boards could have been fitted with batteries from the same bad batch. That is all I can think of for the time being but hopefully it will be enough to get you posting.

	You're on BIOS P1.50 now and you really really should find a way to get flashed to the current P1.80 revision before sinking more money into memory. Try using only ONE stick in rotating it among all four slots beginning at the slot furthest from the CPU. If you find it boots this way, first prove stability BEFORE flashing so you don't hose out a bad flash in the process. And seeings that 2133 Hyper is the slowest of the two kits you have I would start with using one stick of that. Rotating it between slots only after powered down and properly grounded.

	So I finally figured it out. Turns out the CPU was bad after all. As unlikely as it is, they sent me a lemon 6600K. Luckily I had ordered it from Amazon. So getting a replacement was really easy and uncomplicated. As soon as I got the new CPU and installed it, everything started working fine. So I guess the moral of the story is not to overlook the unlikely possibilities. Thank you everyone for your attempts at helping me troubleshoot the issue. Now I have to go start the return process for these extra parts I don't need. Edited by KingTruffle - 06 Feb 2016 at 5:16am

	Its rare but it does happen, glad to hear you have your system up and running now

	I have the HDMI problem too. Like sometimes after being shutdown for a long time, the HDMI doesnt give out any signals, after 2-3 restarts its back to normal. Weird problem, wonder if its mobo or CPU related.
