Memtest’s note “ram may be vulnerable to high frequency row hammer bit flips”. Is it a matter of concern?

[Liby]

Hi guys,

I’ve recently bought a used DDR3 Kingston’s RAM from eBay (HYPER X FURY HX318C10FRK2/16 (2X8 GB) DDR3-1866 CL10) for my old pc because my 8GB (2x4GB) RAM was bottlenecking. I’ve run a memtest at the clock speed and I’ve got no problems, but a note: “ram may be vulnerable to high frequency row hammer bit flips”. Is it a matter of concern?

I can give back the RAM and buy another one, if this could be the better option.

thanks for your advice!

The first pass of Memtest is "maximum hammer rate", second test is at a reduced "hammer rate" so that means under normal use your RAM will be totally fine, since the warning means the memory failed the first test but passed the second.

So would it be advisable to return it?

Are there other tests that I can do to test them?
