Is it possible to get DDR3 memory that's not affected by rowhammer? ECC is reportedly not a full fix and not viable since the boards I'm looking at don't support ECC anyway. I've seen claims that, because the issue is density, smaller modules (possibly 512MB, 1GB, or 2GB) are less likely to be affected, but no actual guidelines for reliably purchasing rowhammer-immune ram. For example this paper suggests that at least some brands are not affected in small sizes:
Does anyone have actual reliable information for buyers?
