- This sort of shenanigan is why it’s important to have a competitive market for CPUs.
- If my memory serves me correctly, this feature was never marketed by AMD for these CPUs and was unstable.
The only mistake AMD potentially made here is not being transparent why it was disabled.
by ChocolateGod - If it can be silently removed was it a security feature?
Whilst I hate companies paying engineers to make things worse just to segment their market; I am not really seeing this as an important feature outside the data-center? If an evil-maid has hardware access they hack the USB and/or PCI not the RAM surely?
by ZiiS - I don't know how this works but does this mean if someone gained physical access to your locked running computer, they could gain access to your full encrypted drive and anything saved on disk?
My reasoning there is if you used an encrypted drive, the decryption key you type when booting up would be stored in memory for the duration of that boot.
This seems alarming because it means if someone broke into your living quarters they can bypass all forms of disk encryption if your machine was on and locked. Encrypting your disks seems like a reasonable thing to want to do with consumer grade hardware.
by nickjj - I had this enabled as it protects against RAMbleed/ECC errors, so it's not limited to physical attacks.by Integer
- It's pretty crazy that we have this entire segment of features that companies artificially restrict from the average person and overinflate the price of, for no real reason. GPU virtualization is another example of such a feature.
The market segmentation arguments don't really work either, enterprises are paying the big bucks for more than just these standalone features.

- This was never marketed as a feature of the consumer CPUs and if some malignant actor does get physical access to my (consumer) hardware, then them being able to read out bytes through cryo-freezing the RAM really isn't high up on the list of things I'm going to worry about.by thg
