« on: October 26, 2016, 06:35:11 PM »

but you can protect your home PC's by adjusting the refresh rate of your ram in the Bios

Mobile phones are going to be difficult because they are all factory set with no way to adjust them :no:

For computers, after running memtest, I thought it should be fairly obvious that you shouldn't be using memory settings (or bad RAM modules) that don't pass the tests.

Reading further into this, DDR4 and above ram will be most affected, especially if over clocking on tight timings.
Slowing down refresh on fast memory will reduce the chances of the rowhammer effect.
