Good news! On the firmware side there is some serius work being done to support it!

https://www.basicinputoutput.com/2025/01/amd-opensil.html?m=1 is AMDs work to opensource hardware intialzation

https://opensourcefirmware.foundation/projects/ Has a good list of mostly BIOS/UEFI replacements.

Idk about memory, Usb, sata or PCIe controllers though. (something else?)

If that was an option I’d still be rocking my i7 920 with tri channel ram. That sucker could take anything I threw at it until the mobo started dying in 2021.

The only new mobos I’ve found with an lga1366 are dual socket server boards.

Had my i7-920 for 11 years. Started with 6 GB RAM and updated to 12 GB later. Went though 4 GPUs (just upgrading, none died). Changed from HDD to The machine was still going when I replaced it with a Ryzen a few years back.

What do you mean? It is a delight to program a riscv chip (compared to the bag of legacy of x86)

I have very mixed feelings about RISC-V since the non-profit organization moved their headquarters to Switzerland after taking a bunch of US tax dollars and grants to develop it at UC Berkeley.

With how things are going in the US right now. I’m not mad about people moving certain groups out of the country. I’m sad, but not mad.

Note: I know the reason they moved to Switzerland is unrelated.

It’s an open source platform: if an american company makes and arm device, they need to pay tax to a British company. RiscV require not to pay IP tax to any foreign country.

Also, it’s not like “they move”: stuck there in the US, they would simply shut it down. So I don’t see how your tax money went in better use.

The firmware is probably going to be the hardest part. I have heard that people who write micro code are rare and far between.

That chips for modern boards need to connect to multiple buses. I’m not saying it’s impossible, but it might make a board significant larger.

Yes, a hardware person I met through a family member said it’s hard and had they known how complex they would have chosen another dicipline
