Yes, the article mentions it:
> What if I have ECC-capable DIMMs?
> Previous work showed that due to the large number of bit flips in current DDR4 devices, ECC cannot provide complete protection against Rowhammer but makes exploitation harder.
- hinkley 5y agoIt sounds to me like ECC isn't being included in the DDR5 spec due to magnanimity so much as because it doesn't function without it. That ECC has become 'load-bearing'. Does that mean we need an extended ECC to deal with critical systems that require additional robustness?

- RedShift1 5y agoIt's just a matter of time before someone finds a way to exploit the ECC part, calls it Hammerrow and brings us back to square one...
- aaaaaaaaaaab 5y agoRowhamming would be a better pun, as DDR5 uses a Hamming code for error correction.
