I added two sticks of the identical spec for spec memory to my system, I've done two Memtest86 v10.6 Free version passes with 0 errors, but there's this message in the notes.
Ram my be vulnerable to high frequency row hammer bit flips
Not getting the error with the original two sticks.
Everything I'm seeing online is saying it's more to do with a security vulnerability and that changing the sticks probably will not make a difference. Someone else said they updated Memtest and it went away, but I'm running the latest atm. Although the original two sticks that were in the system were ver 8.3, were is the new sticks I added are ver3.24.
This sounds like an old exploit, but I'm more concerned with the stability of the memory and not getting corrupt data. Again, I'm on my 2nd pass with 0 errors. I don't understand this error.

This doesn't sound good
The Hammer Test is designed to detect RAM modules that are susceptible to disturbance errors caused by charge leakage. This phenomenon is characterized in the research paper Flipping Bits in Memory Without Accessing Them: An Experimental Study of DRAM Disturbance Errors by Yoongu Kim et al. According to the research, a significant number of RAM modules manufactured 2010 or newer are affected by this defect. In simple terms, susceptible RAM modules can be subjected to disturbance errors when repeatedly accessing addresses in the same memory bank but different rows in a short period of time. Errors occur when the repeated access causes charge loss in a memory cell, before the cell contents can be refreshed at the next DRAM refresh interval.
