Working without BSOD in single channel mode now. Just wish it would work in duel channel mode too.

Wow. Glad I found this post. Same issues with RAM on my z890. I?™ve got Corsair ddr 5 6200 mhz Ram. Having issues with BSOD all the time. Have to under clock just to get past BIOS screen. Wont run at XMP speeds or enters reboot loop. Got some different brand of RAM coming today. Will try that. If that doesn?™t help. Boards going back.

Even having the same problems with the Z890 Steel Series. I've went through all the same rigorous trouble shooting as you all have. Only B1 and B2 work. ram tests fine cpu tests good not just with the cpu diagnostic tool but also in another z890 board. This happened with an older asrock board with a 13th gen cpu. went through cpu's and ram before i figured out it was the board.

Been also dealing with this issue. Been having a lot of BSOD and Random Crashes. Tested everything out and it feels like my MB is really the culprit. Tried rolling back bios versions but didn't help and noticed there was a NEW* Bios version 12/27, but even after the updates the problems still persists. I am thinking of switching it out completely this month.
Current Build: i9-13900k G.SKill 6400Mhz/64GB (Dual Channel) AsRock Steel Legend WiFi Z790 RTX 3070 Samsung 980 PRO 1tb Please let me know if anyone solved this issue everyone is having. |

If you have both RAM modules in the A slots then you are not running in dual channel.
A and B indicate the channels, if you have RAM in A1 and B1 or A2 and B2 then you are running in dual channel. 2 RAM modules installed does not mean you are running in dual channel, they must be in the correct slots: A2 and B2 (recommended) -> Dual channel A1 and B1 => Dual channel A1 and B2 => Single channel A2 and B1 -> Single channel A1 and A2 -> Single channel B1 and B2 -> Single channel The confusion is caused by how DDR5 works. As far as I understand it, DDR5 modules function as if they are 2 modules in one (ie, Dual channel). If the information I have been looking at is correct that means that dual channel is actually quad channel with DDR5. This is irrelevant when it comes to performance however because regardless of it being "dual channel" you are still losing half your bandwidth with both modules in the A channel. Once 3rd party monitoring apps are updated for the new standard properly it will stop being reported as dual channel with a single module or both modules in a single channel. The TLDR is that you should return your CPU if you are unable to get the RAM to work properly in slots A2 and B2 or A1 and B1. That is a strong indication of a weak or even bad memory controller on the CPU. I hope this makes sense. |

Yeah, it's still not very common but it does happen more than it used to. Given
that this is a manufacturer's forum it's not odd that we see it more often here. Most people immediately suspect the motherboard, which makes sense, some part of it isn't working right. Not many people are aware that the memory controller is on the CPU. |

It was the CPU for me, returned it and got a replacement and it worked just fine.
I haven't had a CPU issue in forever, not a pleasant experience. |

Unfortunately, most of the time when I see this issue it turns out to be the CPU.
The CPU contains the memory controller and they are quite prone to dying and even be DOA. Dual channel = 2 memory channels and it's quite common for one to be dead or die, both on AMD and Intel. To put your mind at ease however, they will almost always be dead on arrival or die within a very short time (hours to days). It tends to happen when the CPU only barely passed the testing phase after production. Edited by Xaltar - 12 Apr 2023 at 2:45am |

I've tried another motherboard (MSI Z690 Carbon) Same problem, so seems not to be motherboard issue.

I9 13900K
Z790 Steel Legend Wifi Kingston KF556C40BBK2-64 x 2 64GB kit I got the same issue, DRAM led on, restarts and tries again endlessly. Managed to get it to boot with 1 stick in A2, upgraded BIOS to the latest version (Z790-Steel-Legend-WiFi_7.04.ROM) to no avail. Tried disabling ASRock optimizations and choosing XMP1 still to no avail, won't boot with A2-B2 or A1-B1, similarly to single stick in B1 or B2. Boots fine with 1 stick A2, didn't check A1 Ram is good since I used it and tried it again in an older configuration (a Z690 with 12th gen) with no issues. Is there no chance to run this? Is this ram simply not actually working on this card/bios? What alternatives do I have except returning the MB? Help! |
