Seems like it doesn't apply to older machines, I have AX41-NVMe, it's not on the list, I also didn't get any notification from them (and they usually send some) - no need to panic if you're longterm customer.

I hope it stays like that for a while, but I suspect it won't.

Advertised prices for my setup are now roughly 2x what I'm currently paying.

Seems the driver is DDR5 memory, DDR4 servers are not affected from my quick look.

That'd be nice. The only server I can't host at home is basically just ferrying bytes to and fro, to have the right IP address for email deliverability. I'd buy DDR0.5 and a Pentium 2 if they'd offer it
