NO. The RAM here is all DDR4, same speed, and the only difference is one stick is 8GB. (I may add another 8GB sick at some point, but it won't be soon.) When I said I *saw* no performance difference I meant exactly that. I have a simple attitude about stuff like this: if I cannot*perceive* the difference in normal use, I don\t *care*. I have better things to do with the time than spend it running MEMTEST to detect a performance difference I won't *notice* in use. My needs are modest, I don't push the envelope on my system, and what I have is actually overkill for what I do. My concern is a stable system that Just Works, and I have one. I appreciate your concern, but the only reason I ever ran MEMTEST was if I had a memory fault, and the last time was years back.. > Felix Miata *** http://fm.no-ip.com/ ______ Dennis _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
