AMD will reinstate memory encryption on Ryzen 9000 CPUs via BIOS update in July (opens in new tab)

> TSME isn't a critical security feature for most consumer desktops, as it protects against attacks where the attacker needs physical access to the device.

If you think it's hard to gain physical access to a consumer desktop, you're out of touch. Most desktops aren't locked inside a datacenter. Memory encryption is a valuable desktop (and laptop) security feature.

I'm a little puzzled by the uproar given that all the oneline chatter seems to suggest nobody is using this. If this was AVX512 or something I could understand the give it back reaction...

They’ve been doing a bunch of stuff in agesa updates regarding memory stability lately, and also recently broke and fixed setting manual speed on DDR5 memory with ECC enabled (basically any setting higher or lower than 5200mhz or something was ignored).

I wonder if this was also something they just accidentally broke, or if it was an incompetent attempt at larger segmentation.

I wish they could enable use of non-ECC ram on Threadrippers.
