Ryzen APUs, which include almost all AMD laptops, actually have ECC fused off in silicon unless you buy the "Pro" variant.

- vladvasiliu 4y agoHuh. I didn't know that. My particular laptop does have a "pro" CPU. However, I would be surprised to no end to learn that it supports ECC. This particular model sports an MBP-level price tag [0], but is absurdly cheaply built. Even for "customer facing components", that are easy to compare, such as the screen (terrible colors) and case (creaks if you look at it wrong). HP doesn't offer ECC RAM, not even as an upgrade, so I really don't think the additional lines are physically present. --- [0] I don't remember the specific number, but it was within 100 € of a 14" M1 MBP with 32 GB RAM and 512 GB SSD. That's counting a RAM (8 -> 32) and SSD (256 -> 512) upgrade which were made with components bought separately (though they were rather high-end).
- throwing_away 4y agoI have a Ryzen 2600 (CPU not APU) and ECC works. I wonder what generation ECC fuses became a thing?
- my123 4y agoECC fused off was never a thing on the CPU-only dies, just on the APUs.
