Hello There, My config Motherboard: ASRock X570 Steel Legend Processor: AMD Ryzen 9 3900 X RAM: HyperX Predator 2*16 GB Kit - HX432C16PB3K2/32 Power suply: FSP Hyper M85+ 650W Bios version: 2.30 Operating System: Windows 10 64-bit Pro Power cable connection: Tried two configs 1. 4-pin in ATX12V1 and 4-pin in ATX12V2 2. 8-pin in ATX12V1 and ATX12V2 not connected. When I put the two RAM modules in A2/B2 slots the PC resets 3 times and after that it can POST successfully (with fallback default config). Before enterning bios there is an error message visible on the screen: Memory PMU training error at socket 0 channel 0 DIMM 1 When I enter bios, on the main page only RAM in A2 slot tells 16 GB, DIMM B2 sias none. This is the case for default UEFI settings and for XMP profile also (tried both XMP-3000 and XMP-3200). However in OC Tweaking under DRAM Information both RAM modules are visible in slot #3 and slot #4, with different serial numbers. Also CPU-Z (in Windows) can see both modules and a total size of 32 GB. I am able to boot with 2 RAM modules in A1/A2 with default bios config (DDR-2400) and also XMP-3000 and XMP-3200 works fine. With a single RAM module in B1 or B2 the PC won't POST, unable to reach bios. (I cleared CMOS every time I changed the RAM placement) Do I need to connect all 12 pins of ATX12V1 and ATX12V2 connectors? (This section of the user manual is quite ambiguous in my opinion. A detailed explanation of the different powercable connection options and their effect would be helpful.) What further config may I try? According to the datasheets I consulted my RAM kit is in the QVL Matisse list, also the Ryzen 9 3900X should be compatible. What am I missing here? I started to think that my motherboard is damaged somehow and I am struggling in vain here. If that is the case is there a way I can get proof of that? Any help would be appreciated. I am troubleshooting this issue for way too long now. (on the expense of work time in the solitary of home office quarantine) Best regards, Balint |

well ... for one .. you have a higher power requirement for your CPU .. if your current PSU doesn't have the outputs to plug into ALL your motherboard power ports .. ie .. 24pin .. 8 + 4 pin plug ins ..then I recommend getting a new PSU and then go from there. I run the same mobo and memory without issue.... and even run my memory at 3600mhz with infinity fabric set to 1800 ------------- |Ryzen 5 5900|ASRock X570 Taichi-BIOS 4.60|2x16GB HyperX Predator RGB 3200@3600 1:1 IF|ASRock RX 6700XT|2 x PCIe 4.0 M.2 Drives for OS & Games|850 WTT Seasonic 80+ Titanium PSU|Noctua NH-D15| |

You need to plug the 8 pin. Generally, connecting 8 pin is enough, this provides 235W of additional power (some also comes from the 24 pin). Additional 4 pin is excessive on AM4 and can be ignored. 650W should be sufficient with a low to mid-end GPU. If you have a 250W+ GPU (even if it's an old one), you will probably need 750+W PSU. |

Thanks for the answers guys. My graphics card is Radeon??RX 580. It consumes 185W according to its specifications. I am getting a new 1000W PSU from a friend for try, which have enough pins to connect all 8+4 power connector pins. Other question from my post: Is there a way to detect if my motherboard is permanently damaged? |

Is there a reason for you to suspect the board is damaged? Did you buy it used or something? I guess these are dual rank sticks which is harder for the memory controller to drive. Make sure you enable Gear Down mode and disable Power Down in memory settings. Then you can try 2T command rate instead of 1T. Then try running them at lower speed, like 2933 MT/s, or play with voltage and timings: try running with 1.4-1.45v, or increase tRCDRD a couple of ticks. |

The only reason why I think my board might be damaged is because I cannot think of anything else. I bought this mobo new from an official Hungarian reseller. I think I might have damaged it somehow inserting and pulling the memory sticks in and out a couple of times now... Thanks for the tips. I try these out then post the result here. |

I tried Gear Down mode enabled and Power Down disabled, command rate at 2T. Tried with XMP profile 3200, and default 2400 MT/s with default timings, and also increased tCAS, tRAS, tRCDRD, tRCDWR. All configs had same effects. POST fails, then reset, this happens 3 times, then the PC boots with default BIOS config. I am loosing hope here. Thanks anyways. |

bios version 2.6 says something about improve memory id be inclined to try the latest bios remember to reset bios to defaults first and i would STRONGLY SUGGEST only one stick of ram in slot a2 ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

I updated the BOIS to 2.60. I see a new menu point in OC Tweaking called DRAM Profile. But that seems to be for Corsair RAMs only. However I gave it a shot anyway at 3200 MHz. Also 2400 MHz and 3200 MHz with XMP profile. Still no luck, same effect with the 3 times resets then default settings. |

i feel safe to say there seems a problem with your board to be honest ram on later ryzen platforms should be relatively easy we left all the wierdness behind with x370/ryzen 1000 series ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Yeah, unfortunatelly I feel the same. But I give one last shot and test it with another PSU 850W with all 8+4 power pins connected. I read at a couple of places that others had issues with Ryzen 9 3900X when only 8 pins were connected. https://www.evga.com/products/product.aspx?pn=220-p2-0850-x1 Others also wrote that the video card installed in PCIE slot 4 caused them trouble. However I also purchased a too big cooler that blocks PCIE slot 1. (BE QUIET! Dark Rock 4) But is there of a way to get proof of actual hardware failure? I want to try every option before going down the hole of RMA. Because the PC is stable when I do not install the memory to work in dual channel. |

| Try anther memory kit if you can. Maybe it's the memory that's buggy, not the board. |

Phew, so I am not the only one with this problem. When I place both memory dimms in the first to or the last two slots there is no problem. When I try any dual channel configuration it just gives the memory training error. I did not use any overclocking options, did not even select the 3200 speed yet, just kept it on default for a while. Could the board really be broken? |

With this kind of thing I have noted that it tends to either be the RAM, not compatible or the CPU has a defective memory controller. If you search the forums you will see other threads where forum members tried multiple boards, different RAM and even different board manufacturers, only to discover it was the CPU itself that was the issue. When memory controllers were integrated into the motherboard these issues typically were caused by a faulty board but these days the memory controller is integrated into the CPU (IMC) and the CPU is by far the more common cause of RAM related issues like this. I don't mean memory compatibility, that can be improved with BIOS updates etc but when dual channel doesn't work it's either the CPU, bad RAM or the RAM isn't fully inserted into the slot. Make sure the RAM is all the way seated in slots A2 and B2, it may work fine in single channel but not in dual if one side is not properly seated. -------------

| Thanks for the advice, I think I will order just in case a new set of ram. (if the new set works it means I have more ram) and if that did not fix the problem I guess the problem will be the CPU or the board and I will still have more ram when I replace the CPU and MOBO at the end of the year. |
