You might want to consider the x570 Steel Legend ..it officially supports 4 x 32gb modules .. or a different x570 chipset mobo ..

Hi ThreeDee

Thanks for coming back again on this, much appreciated.

I did look at the x570 options before I decided to go for the x470s. They are, generally, a lot more expensive than the x470s for performance and spec I simply don't need, but the main thing is that they all (except one, which is eye-wateringly expensive) have active cooling on the chipset. I am deliberately targeting a near-silent build (I have a BeQuiet 750W PSU and a NoFan CPU cooler rated at TPM 80; the x3700 is rated at TPM 65) and an x570 board with active cooling will completely ruin all that. Hence looking to ensure I can get an x470 board that'll work.

I know the x470 chipset CAN support 128Gb; I was looking at the MSI range initially (Gaming Pro/Plus Max; Pro Carbon etc) which all list 128Gb as official max RAM, and I know they all CAN support the x3700, but, initially at least, they needed a BIOS upgrade to do so; like I said I can't do that here as the Taichi doesn't support USB Flashback (unless someone can confirm otherwise...?)

The only other option I guess is to find a vendor who'll ensure they flash a board for me before they ship it..? But I was hoping now, about a year after initial release, they'd come with a BIOS that supports these two points out of the box ...?

Do you (or does anyone) have any thoughts (or ideally be able to confirm) here please?

Cheers

The active cooling on X570 boards is manageable. If you don't install anything into PCIe and M.2 slots connected to the chipset (the lower ones), it won't heat to the point the fan needs to be spinning. Otherwise, you can set the fan to be running at lower speeds and only fully spin up when the temps are in the 80s C. Even a little airflow is much better than convection, and you won't hear the fan running at 30%.

Memory support mostly depends on CPUs these days due to the memory controllers being integrated into the CPUs instead of motherboard chipsets. I guess the 64GB quote for X470 boards is there because the boards were released with Ryzen 2000 generation that officially supported 64GB. Ryzen 3000 CPUs support 128GB.

i also use scan
they used to offer free flash when bought with a 3xxx cpu

but hey ho
to be fair theres a good chance now 450/470 boards are coming into uk retail chain already with ryzen 3000 bios
my wifes 450 came already flashed from asrock last month with 3000 bios

as a tip check your box the 470 comes in
if its got a ryzen 3000 ready sticker/label ask for the tenner back
