Hi, Just built a pc... asrock b450m steel legend motherboard, but my 2 memory modules don't run as dual channel. Paperwork says to use A2 and B2 slots... which I have. Ram is: Crucial Ballistix Sport LT BLS2K8G4D32AESBK 3200 MHz, DDR4 Any Ideas please ? |

Thanks for the swift reply... reseated the ram, swapped them over, even tried the other 2 slots and it's exactly the same :-( bios screen sees each module, and reports the full 16gb - as does Windows. Downloaded cpuz and it reports dual channel! so now I'm well confused.. is it really running dual channel or not? Running bios 2.9 as supplied - all the pictures ive seen actually say dual under the ram on the main page, so I'm lost here. Any more ideas please ? |

| If you put the sticks into proper slots (staggered), and have the full capacity available, it runs in dual channel, that's just how the slots are wired, there's no software toggle. |

so are we saying that it IS in dual channel mode ? I was relying on the bios screen (v2. 9) reporting that, unless they have changed it ! |

It's hardwired. If you are using A2/B2, and you have 2 8GB sticks, and it's reporting 16GB memory total, you are necessarily running dual channel. There's no other possibility. The A slots are wired to the A channel and the B slots are wired to the B channel. |

Looks like it working properly then... they must have removed the option from the bios - which is what caused the confusion. Thanks to all who replied... far better support than from ASRock (who never seemed to grasp the issue) Thanks again, stay safe guys. |

Just got an email from the techs... would have removed all the confusion if they'd left it in.. : Thank you for the update. Dual/Single channel is indeed not reported in BIOS anymore. As far as I know it has been removed from the latest AGESA version. I will ask my colleagues in Taiwan if they can bring it back in a future BIOS version, or ask AMD to integrate it in a future AGESA version (if it is really AGESA related). Thanks! |
