I am casting about for a thorough, reliable memory test that can be left running for a while, stopped and then resumed from the address/position it was stopped at if I make my meaning clear. Case in point: I have been recommended Memtest86+ and I assume it does the job well but for obvious reasons you have to run it from a bootable disc. Which of course means that the PC is unavailable for the duration. This morning, before leaving home at 8 am, I booted into memtest figuring that by the time I'd be back at 4-5 pm it would be done, but no; it was still chugging along when I came home. That's 8 solid hours and yet I have only for 4 GB's of RAM. So, a memory test that would let me do the operation in chunks as described above would be the answer but is there such a thing? Thank you.
