Good afternoon! I'm new here. Before I explain my problem, I just want to tell that my english is not perfect, but I will do my best to make me understand So, I just bought a new motherboard, a new processor and new ram: Motherboard: Asrock X370 Gaming K4 Processor: Ryzen 5 1600X RAM: G.Skillz F4-3000C15D-16GTZ BIOS: 2.40 (lastest update) I've made some test during the last days. Everything run smooth except the RAM. I'm stuck in Single Channel in the bios. My ram are in the a2-b2 slots. As soon as I change the frequency in the bios, my computer start to bootloop like power on power off and after It starts and the frequency is stuck to 2133 and in Windows, it says that I have 16Gb, but 7.5Gb usable. I've tried with other RAM (Geil EVO X 16GB 3200) and I'm having the same issue I'm desperate, I don't know what to do

Hello, just want you to know that some people reported the same problem (me included): http://forum.asrock.com/forum_posts.asp%3FTID=5312&PN=1&title=ram-stuck-in-single-channel" rel="nofollow - http://forum.asrock.com/forum_posts.asp?TID=5312&PN=1&title=ram-stuck-in-single-channel http://forum.asrock.com/forum_posts.asp%3FTID=5053&KW=&title=bios-no-detecting-dualchannel-memory" rel="nofollow - http://forum.asrock.com/forum_posts.asp?TID=5053&KW=&title=bios-no-detecting-dualchannel-memory |

I will bring it up with Tech Support. I do know that there is a UEFI update in the works for the X370 Gaming K4 that will likely resolve a lot of memory incompatibility issues. I am afraid I don't have a time-frame however. -------------

" rel="nofollow - i've had that problem on my board and it was defective ram. Since you have tested other ram and the problem is still there it may be a faulty motherboard in your case. Have you tried the other ramslots? Try with only one stick slot by slot, if you find a slot that doesn't boot you can be certain that the mainboard is the culprit.

| If you tried with the same RAM module and it worked in one slot and in another it didn't then it's the Mainboard. |

A bent pin/pins on the CPU can cause issues like this. Check the CPU and make sure there are no bent pins. If there are none then return the board for replacement. -------------

| The weirdest thing beyond this is that I see the RAM in slot b2 but when I try to start it alone, it dosent work |

First, the Ryzen memory controller does not support a memory speed of 3000. It must be set to 2933 maximum instead. Memory compatibility and problems are the main issue with Ryzen boards. The boot loop, power on and off cycling is the AMD Advanced Boot Training feature, that is performing memory training. That happens with Ryzen systems when it detects the memory will not work at higher speeds. The AMD Advanced Boot Training feature is an option in the OC Tweaker screen. Are you only changing the memory speed/frequency? You should be setting the DRAM voltage to 1.35V when you set the memory speed above 2133/2400. The XMP profile on the G.SKILL memory was designed for Intel Z170 and Z270 boards, and will not usually work on a Ryzen system. Check the QVL list here: https://www.gskill.com/en/product/f4-3000c15d-16gtz" rel="nofollow - https://www.gskill.com/en/product/f4-3000c15d-16gtz Some memory like this that was designed for Intel systems will work with Ryzen, but normally that is memory that uses Samsung memory chips. Have you tried both memory sticks/DIMMs of both memory models in the B2 memory slot? Are you sure that the memory was completely seated in the B2 slot? Since you have the same problem with the B2 slot with both models of memory, it is possible that the board has a problem. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Thank you for your answer. I've just made the test to make sure. When I tried both on A2 B2 slots it bootloop and get stuck on 0d code. Pretty sure now that I have an issue with the board. Asrock support told me that I have to remove the cooler, the cpu and the ram and after to clear cmos and then put in everything back. I have a question. Could it be because my Water Cooling is higher then 95W? In the book it write that the cooler has to be lower then 95W |

The cooling capacity of the CPU cooler has nothing to do with memory compatibility or memory over clock potential, except if it is too low. It is impossible to have too much cooling for a CPU. The more cooling you have, the better it is for a CPU. Where does it say in the manual that the cooler has to be lower than 95W? Do you mean this from the specifications: Supports 95W Water Cooling That does not mean the CPU cooler cannot be better than 95W. The best Ryzen 7 processors have a TDP of 95W, and this and other ASRock AM4 boards will support CPU coolers that are capable of at least 95W. Some of the fan connectors on your board will provide enough power for custom water cooling pumps, that can provide much more than 95W of cooling even with small radiators. That specification is a little confusing, but I can assure you that your CPU cooler's cooling ability is not causing your memory problem. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Please read 0d Code reference at: http://www.asrock.com/support/faq.asp?id=334 What video card are you using and what PCI(e)slot does it occupy? |

| " rel="nofollow - [URL=][/URL]I've just think about something that can cause this. I know that the guy who make my build have use a drill to enlage the holes where the cooler is mounting because my current cooler was not fitting. He looks under my board and said that there is not circuit. I was reticent but he said that there will be no problem. I also didnt see any circuit on the board, where the hole is located but could have one in second layer? |

There is the problem  Never drill the holes larger on any modern board, they can have 8 layers or more. Particularly the ones around the CPU socket as those areas are extremely dense with traces. What is worse is that your warranty is void too  I am using my Corsair H105 with the standard AM3 bracket, I have not been able to get an AM4 bracket for it. My solution was to mount it using only 2 of the 4 mounting points and it works just fine. Never modify the board in any way unless you know exactly what you are doing and what effect it could have. Also be sure you don't care about the warranty. -------------

It looks like you are stuck with single channel on the board, it could be a lot worse I guess. For most tasks and gaming it shouldn't be noticeable. I wouldn't trust that friend with your PC from now on though  -------------

" rel="nofollow - Ok then now I'm fixed of what is the issue. I will not take it any further. Then I have another quetion. I have an idea to "fix" my problem 1 - Should I buy a new motherboard? 2 - I have 2x8gb G.Skillz Ram at 3000mhz. Should I exchange it for 1x16Gb at 3000mhz? Will the result be the same if I run like that? Its for gaming so I want the best at all Thanks |

The key with Ryzen in the fact that the infinity fabric runs at the same frequency as the RAM, dual channel makes no difference to that so it would make little to no difference if you swapped to a single 16gb module. The only difference I could see being possible is being able to achieve a slightly better overclock on your RAM when using a single module. Given it is a 16gb stick it may not work that way because 16gb sticks can be harder to overclock. Personally, I would replace the board in case there is other damage to it that will over time damage the rest of your system. -------------
