How to test and safely keep using your RAM

How to test and safely keep using your janky RAM without compromising stability using memtest86+ and the memmap kernel param.

    Well done. I recently revived the BadRAM kernel patch in order to do something similar; memtest86+ supports that functionality too, using <F4>, <F4>, <F10>, <F10>.

      I’m curious: What’s motivating you to do that when the memmap param can do the same without patching?

        BadRAM specifiers can apply to stripes of memory corresponding to certain physical hardware failures. The memmap hack only allows for contiguous allocations. BadRAM’s intended for repurposing consumer-grade RAM that might normally be thrown out, not for reconfiguring motherboards that have strange layouts.
