What is B450 Matisse memory support status?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   At ASRock site, none of the B450 motherboard specs are updated to show Matisse memory support.

Do the motherboards with B450 support DDR4-3200 natively with Matisse?

Thanks!

	On B450 ITX/ac with its current BIOS it doesn't even boot on anything higher than DDR4-2133. Even memories running at 2400MHz stock are having boot loops, not to mention XMP profiles :)

	Hmm interesting, but perhaps you just need a bios update? Other B450 boards seem to have some updates that B450 ITX/ac does not have. Also ASROCK B450 Gaming-ITX/AC AM4 MITX is not listed at ASRock site anymore... is it EOL? I would not mind using the system with decreased memory speed if the issue will eventually be fixed with an update. It would be annoying if there was some hardware issue. On the other hand I do not want a X570 with chipset fan. I think I have to see that motherboards with failed fans will not become junk first.

	With the current problematic AGESA bios part from AMD for Matisse it is Not too bad, that this CPUs cannot be found in the Specs of these boards. Anyway all (or the most) B450 boards at least have AMD AGESA Combo-AM4 1.0.0.1, the first for Matisse. But these version doesn't make any user happy. I would stay away from that until final Bios versions will come up. At the time when the AMD 3950X will be available, the bios firmware for the current Matisse will be better, i believe...

	@Ray62 not sure if the problem is AMD here. MSI has many modules working with B450M boards even cheapest ones... See: https://www.msi.com/Motherboard/support/B450M-MORTAR#support-mem-19 They have updated to AMD ComboPI1.0.0.3ab Perhaps the beta bios can help @PeterCxy :) Do you know how come some random german store has access to this bios and nobody else?
