Any word on official ECC support? (And I don’t just mean it can use the RAM, I mean for it to gain the actual benefits of ECC)

Any word on official ECC support?
(And I don’t just mean it can use the RAM, I mean for it to gain the actual benefits of ECC)
- cesarb 4y agoThe most official thing I've found about it so far is a line at https://www.amd.com/en/product/12166 https://www.amd.com/en/product/12166 (source: https://www.amd.com/en/products/cpu/amd-ryzen-5-7600x https://www.amd.com/en/products/cpu/amd-ryzen-5-7600x) which says "ECC Support: Yes (Requires mobo support)"
- Already__Taken 4y agothe line they've had for a while is that's entirely up to the motherboard vendor to qualify
- devonkim 4y agoDDR5 JEDEC specification includes essentially a form of ECC so it may not be _as_ big of a deal for many users. It also means that setups on AM5 will have some level of ECC handling functionality on both the chipset and the CPU.
- wtallis 4y agoThe ECC that is standard with consumer DDR5 is purely on-die, protecting the data at rest but not providing any ECC for the memory bus. It's transparent to the host system. As a result, the CPU and other components do not even have the option of participating in that ECC. It's not a substitute for and does not preclude the use of module-level ECC as in previous generations. On-die ECC also isn't new with DDR5; it's been used for years on at least some LPDDR4 and LPDDR4x memories (eg. https://www.micron.com/about/blog/2017/february/the-advantage-of-ecc-dram-in-smartphones https://www.micron.com/about/blog/2017/february/the-advantag...) and even longer for special-purpose DRAM parts.
- lodi 4y agoI'd be surprised if it didn't support ECC; every gen since Ryzen 2000 has supported ECC (although it's unadvertised and you have to be very careful with motherboard selection). I currently have proper ECC running on a 3000 series Ryzen with an AsRock motherboard.
