Hi all, I bought the motherboard in subject for my new pc. The cpu is i5 6600 and i have installed samsung 950 pro ssd on m.2 slot. The motherboard arrived to me with 1.60 firmware and i had same issues to get ssd recognized from bios and, also, some times my display reports incorrect input signal and black screen, but this just sometimes. So i decided to upgrade firmware to 1.9, and the process finished correctly. but now I'm not able to verify if there are same recognition issues yet because display, after a few seconds (20-30) from start , continues to report incorrect input signal but now it happens every times i turn on the machine. I tried to change display, it is the same model but different one, but i have the same issue. display is connected to motherboard through HDMI. How may i understand if it is a gpu issues (ie gpu integrated in cpu) or if it is something else? is there something i could configure from bios to resolve this problem? and then, but at this point it is secondary  , what is the correct bios configuration to allow motherboard to recognize samsung 950 pro?thank you very much P.S. i hope my english is enough undestandable

updating... i was able to enter in advanced bios page and set "full hd uefi" to disbled before display becoming black and after restart i set in advanced/chipset configuration page "primary graphic adapter " to Onboard. Well now display don't became black definitively but sometimes i have an image flickering or one second black screen. At the end now i am able to use bios configuration tools. probably i still have a problem but now i may work. Suggestions ? regarding 950 pro recognition, i have different information. If i look "boot" page in bios i find in boot option properties- boot option #1 samsung 950, pro but if a look in "advanced\storage configuration" page in M.2 (pcie) slot i find "not detected" and also if i look in "tool\boot manager" page i am not able to select 950 pro in boot device. All this makes sense? thank you very much |

new update... i noticed that enabling CSM and setting all parameters to legacy only in bios, my 950 pro was recognized by bios as bootable device. So i tried to install win 10 pro from dvd and it was installed on ssd directly. The system start now and seems quite stable but there are some things that don't convince to me: -if i turn off the system and then i turn on all works, but if i restart system from windows, display became black but machine doesn't reboot, i have to turn off it manually. -from samsung magician software in system information i see 10 Gbps is correct? (i remember it was 32 Gbps) -during win 10 updating sometimes display reports incorrect input signal although system still working. thank you very much |

Hi i recently bougth the same motherboard and i have the same exact problem with the video. Another guy has the same problem on this italian forum: http://www.tomshw.it/forum/problemi-post-assemblaggio/552098-artefatti-grafici-pc-appena-assemblato-urgente.html I partially solved using a dedicated gpu. I said partially because the main problem is that i paid for a working motherboard and this is not. I'm using ASRock H170 pro4s with Intel Pentium G4400. Can i ask you a question? Did you power your cpu with 4 pin or with 8 pin? Thanks, Stefano Pace.

hi Stefano and thanks for reply, i plugged in "ATX power connector (atx12v1)", it is n°1 in page 1 in quick installation guide, 8 pin did you refer to it?

Yes you can use only 4 of the 8 pin if you don't need more power. For example my PSU doesn't have the 8 pin connector at all and i was forced to use 4 pin. I was wondering if it could be a power problem but if you are telling me that you are using all the 8 pin i can exclude this. Have you solved the problem with black screens using the motherboard video outputs?

little update, i forgot to mention during my attempts to recognize 950 pro i disabled sata controller and, until i enabled it again, display image stopped flickering, it could be helpful to more expert people! @Pasuxable: yes i use integrated gpu on hdmi connection

Hi guys! I wanted to join the discussion as I have the very same problem (exccept the ssd issue, I had no problem with that): I have a AsRock H170 Pro4s motherboard along with a Samsung S22E391HS/EN monitor and I am using an HDMI cable to connect those two. I am using the integrated HD 530 gpu of my cpu (i5-6400). No matter if I am in the uefi or in win10 I keep getting random screen flickering (only the bottom of the screen) and black screens, sometimes they do not appear fo at least 15-20 minutes but sometimes they make it impossible to use the PC. The weird thing is that if I use the Pc with a TV there is no issue. If I connect a lapotop or a PS4 to the monitor there is no issue. The problems only occur when the PC and the monitor meet each other. I have tried putting the RAMs to other slots, tried to disable PC case fans to save power, I have checked all power connectors, removed every drive but the ssd with win10 and an optical drive but nothing helped. Oh, my psu has a 4pin ATX12V connector but I use it with a 4pin-8pin adapter so all 8pins are occupied on my mobo. I also tried to change colour palettes and refresh rates but nothing helped (I thought the problem might be an incompatible screen setting). I have the latest drivers for every component along with the latest uefi from AsRock. It is really annoying as I do not want to purchase a dedicated gpu, I want to use the integrated one. If you have any updates please share it, I will do the same. EDIT: The issue is still there when using a DVI-to-HDMI adapter, blinking and black screens are still there.

| Replacing the board solved the problem for me. Seems that the VGA part of the board was faulty. |

I have the same problem with H170 pro4s. I use VGA-to-HDMI adapter for the monitor. And i have no discrete graphics card. Evry time when I reboot computer I have black screen. I have to swithch off computer manually and wait for 10-15 minutes. When I turn on computer again the problem is disappear. I try to change BIOS setup: select the built-in graphics card as main. But it doesn't help. Has anybody solved this problem?

I also had a problem with no HDMI signal. But my DVI and VGA worked. Very strange The problem with my mainboard was the following: the Ram was installed in the Memory-Slots A2 and B2. Once i switched the Memory-Modules to the Slots A1 and B1 i got an HDMI signal :-) Yeppi!!! I was looking for a solution of this Problem for some days now, i already got the mainboard changed but nothing helped. I am so happy that i found a solution for me that's why i am writing here and hope this information is might useful for someone else. |

I'm glad your HDMI output is working now, and I can't say it did not happen, but it just does not make any sense that moving your memory to the other slots fixed the HDMI output problem. If another user or two did the same thing, move their memory from the A2 and B2 slots (the recommended slots to use with two DIMMs) to the A1 and B1 slots, and that also fixed their problem, I would think that there is a problem with the UEFI/BIOS, or the board itself. After reading that several users had the same problem, I began to think something might be wrong with the HDMI connectors on these boards, or the soldering of the connectors to the board. I also know that bad cables, usually the connectors on the cables, can cause screen flickering and no signal to the monitor. Any type of adapters, like a VGA to HDMI adapter (that must be a powered adapter, that is converting an analog video signal to a digital signal, or digital to analog video, which is not a simple thing to do) can not work properly if not used correctly. Also enabling the SATA controller in the UEFI apparently fixed the video problem for someone?  Sometimes when we work on our PCs, we move things by pressing or pulling on the board, which usually breaks something. But it can also cause a bad connection to be accidentally fixed. I wonder if that is what happened when the memory was moved to the other slots? I would love to know what is actually happening that is causing and fixing this issue.  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Normally having CSM Enabled and all its options set to Legacy doesn't allow a 950 Pro to be used as a bootable device. I don't know if you are correct about the CSM settings, or what is going on. The Magician software shows the speed of ONE PCIe/DMI lane for some reason, instead of the four PCIe/DMI lanes that a 950 Pro uses in an Ultra M.2 slot. One PCIe/DMI lane has a maximum transfer speed of 10Gbps. I assume it is easier to check how fast one of the lanes is, but harder to tell how many lanes are being used, which could be two or four lanes You are right about the 32Gbps speed. That figure is for four PCIe/DMI 3.0 lanes, which are 10Gbps each. But there is "overhead" in the transfer of the data, so instead of 40Gbps (10Gbps x 4) we get 32Gbps. That's caused by 10 bits being transmitted for every 8 bits of actual user data. So the calculation is 8Gbps of data per lane X 4 lanes = 32Gbps. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Sadly i have to say that after some mails with asrock it turned out that my memory was faulty. That's the reason why switching the memory modules in the other slots helped. I changed it now to some other brand (now kingston) and that helped. At least i am getting partially a HDMI picture. The memory i used before seems to have had a bad batch with faulty memory modules on it (16-GByte-Kit Crucial CT2K8G4DFD8213 - micron modules with labels C9BDG or D9RGV on it). These modules also showed errors with memtest and therefore it did not give a picture to me. Anyway ... with a short cable (2 meters) i am getting a signal now - with my 10 meter cable i have flickering :( and with higher resolution it is a bigger problem. The board is also changed meanwhile - therefore i do not think this was a hardware failure of the first board. If i test with my 5 year old laptop with hdmi connected through the 10 meter cable it gives me a clear signal without problems. That is even more strange. And with the asrock board it just shows a picture and then goes black, shows picture again goes black, and so on I tested several bios versions now. Downgraded to 1.30, 1.50 and also tried 1.90 - all have the same problems with the defaults loaded. Could it be that the HDMI signal strength of the H170 board is not strong enought? I also have the feeling if i have other outputs (for example DVI attached) makes it more worse. And somehow it looks like it makes a difference if i have the cables screwed to the bracket or just plugged without screw connection (sorry if i explained it a bit strange/confused but i do not know how to explain it better in english) PS: I forgot to mention... In Linux it gives me a lot of EDID errors... i am not sure if that's a kernel/driver problem (because there are some bugs filed already) but anyway it looks like there is a problem in the connection/handshake. |

What i found out after trying several cables... The HDMI Port of the Mainboard seems to behave strange (loose/bad contact with HDMI cable). First i removed the I/O panel. Then after pushing the cable with my hand to the side it seems to become a connection and show's a picture. Then after pushing to the other side it seem's the connection is lost. This i tried with several cables - all the same. With my old intel board i did not have such problems. As this board is the second one because it was already changed once from the online-shop it seems that this might be a common problem. Having the I/O shield installed seems also to be a problem for me because this forces the HDMI-Cable into a position which causes the cable to have a bad or no connection at all. Maybe someone can verify this. This problem really drives me crazy. I am thinking about buying a DisplayPort to HDMI Adapter ... |

This is exactly what I thought was wrong in an earlier post, a bad connection with the HDMI port. We also know now that moving the memory to the other slots did not fix the problem with the HDMI connector. The memory you were using was apparently the problem. Before you tried some of the memory in the other slots, you did not have a signal from the HDMI port because the PC never completed POST or booted because of the defective memory. The DisplayPort to HDMI adapter is not a bad idea. But this thread is about the H170 Pro4 board. The H170 Pro4 does NOT have a DisplayPort output: http://www.asrock.com/mb/Intel/H170%20Pro4/" rel="nofollow - http://www.asrock.com/mb/Intel/H170%20Pro4/ So you are using a different ASRock board. The lack of information like this in your posts makes me wonder what else is missing.  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Having problems with the H170 pro4 monitor flicker? I replaced the motherboard and that did it! It also fixed another problem that I had blamed on Win 10 and that was that it would hang after doing a power restart. ------------- chill |
